IPhones are now very reliable smartphones, since Apple places great emphasis on their quality, but this is still a technique and, like any technique, be it a computer or a TV, it tends to break down. All these problems with a smartphone put you before a choice, take your smartphone to a service center, where they can rip off a round sum from you, or try to fix it yourself. These instructions are general and will work for all iPhone models.
Let's see what the iPhone firmware is for:
- In case of software failure.
- In case you need to install the current version of the OS.
- If you forgot your password (not to be confused with Aplle ID activation lock).
- To create a clean system after changing the owner of the device.
In this case, you can do very simple steps in order to restore your device to a working state, this does not require the knowledge of a programmer, everything is very simple. One of the easy ways to restore iPhone is to reflash it, for this we need a computer and iTunes. By the way, the same actions are done in the service center.
Before starting the process, do not forget to do Backup your data, music, photos, contacts and other important information, because after the iPhone is flashed, all information will be completely deleted.
Preparation in iPhone firmware
Download the required firmware version with the extension .ipsw... There are different versions for each iPhone model.
You can find out the version of your iPhone very easily, in the firmware files (4s, 5s, 6S, 7, etc.) they usually indicate a set of letters and numbers that can be seen on the back cover of the iPhone, for example: Model A1332.There is a small problem with choosing the firmware, but it consists in the fact that there are GSM and CDMA models that work in different cellular networks. Therefore, you need to choose the model that suits you. Firmware for GSM won't install on CDMA.
After you have determined your model, download the firmware on your PC that is suitable for your gadget, here is the site where you can -
Important!!! Apple does not allow downgrading the OS version, but there is a time window of several weeks after the release of the official ios update, during which the previous OS version will be available to users. 
Another important feature is the ability to return to the latest official version of ios from the beta version installed on the device. 
First, you will need to go to the settings and disable the function Find iPhone without this, you will not be able to flash your device, as iTunes will give an error. Download the latest version from the official website.
IPhone firmware in action
There are two ways to flash an iPhone, via Recovery Mode and DFU Mode. Rcovery Mode, this is an emergency recovery mode. Designed to recover after the smartphone has stopped working normally.
DFUmode - performs actions bypassing the iPhone OS and makes the firmware directly through Firmware... This method is also recommended for owners who have Jailbreak.IPhone firmware via RecoveryMode
Turn off your phone and wait for the screen to turn off and hold down the Home connect it to your PC. The computer recognizes the smartphone in recovery mode.
We launch iTunes and wait for the program to detect the iPhone, you can get out such a window, click OK. 
If iTunes does not react in any way, click on the smartphone icon in the iTunes program and look for the item Restore iPhone press on it while holding the Shift key (for Windows OS) for MAC, hold down ALT. Also in this menu there is such a function as updating the iPhone:
The file manager will appear in front of you, we are looking for our firmware and click Open... Then iTunes will do everything by itself, we are waiting for the download to finish. After the download is complete, disconnect the iPhone from the PC and long press the button Power turn off the smartphone. Then by quickly pressing the button Power turn on the iPhone. That's all the iPhone is ready to use.
Flashing iPhone via DFU Mode
We connect the smartphone to the PC and turn it off, then hold down the Power and Home buttons for 15 seconds. Then release the button Power continuing to hold Home until iTunes recognizes the device in DFU.- Choose your device in iTunes.
- In the control menu we find restore iPhone
- Click on this item while holding down the Shift key (for Windows) or ALT for MAC
- In the window that opens, select the file with the firmware, open it.
- We are waiting for the completion of the firmware process.
- We turn on the device and use it calmly.
This method is suitable for those who have Jailbreak does anyone fail to flash an iPhone through Recovery Mode.
The apple company has long conquered the market with its innovative technologies that delight their fans with new products every year. Many owners of Apple products often face the problem of updating an old version of the OS, especially those users who do not receive updates via Wi-Fi. And today we will talk about how to flash an iPad without the help of specialists. Let's take a closer look at this issue: find out what is required for this process, and also choose the best way to carry it out.
What you need to flash or update your iPad
The required devices, programs, etc. depend on which method you choose to flash iPad 2, iPad 4, iPad mini or any other model. With a regular update, the main thing is to have a stable internet connection and a well-charged device. Well, if you use a computer, then iTunes, a USB cable and various modes of your device.
We recommend that before performing any manipulations, make a backup copy of all files on the device that matter to you. Of course, this is not necessary at all, but it is possible to remove them if the procedure is not very successful. To make a backup, you need to connect the gadget to a PC, launch iTunes and activate the corresponding function. So in any case, the firmware will require an original USB cable.
Updating iPad firmware without a computer
It is not at all necessary to come up with complicated methods if you only need to update the firmware to the latest current version. Most likely, in this case, you only need your device, as well as an Internet connection. It is recommended to change the firmware via Wi-Fi with a high speed and stable connection, otherwise you will have to wait a long time, and it is best to carry out this procedure through a computer.
Important! Do not confuse updating with recovery. When updating, all data such as contact photos and applications remain unchanged, and when restoring, everything is reset to factory settings.
To use this method, open the main section of the mobile device settings and select the section called "Software update". The system will immediately notify about the availability of a new version of the operating system, which is compatible with the version of the gadget. There is a single button that starts the update procedure, so it is impossible to get confused - all processes take place at an automatic level.
Firmware via Recovery Mode
Unfortunately, it is not always possible to update the firmware using standard methods. Although very rare, it still happens that the program crashes, and an error message appears on the screen. You can try to restore the gadget by returning its state to factory settings in Recovery Mode. First you need to activate it:
- Turn off the tablet, hold down the Home button.
- After 5-10 seconds, connect the USB cable to the device - the iTunes logo, an arrow and a plug should appear on the display. This means that you did everything right.
- Open iTunes on your PC, agree to transfer the gadget to Recovery Mode, click on the "Restore" button.
- The system defaults to the most recent one available. If desired, you can select a different version by holding Shift or Alt.
- After this operation, the firmware will be replaced and just in this case a backup copy is required, since all data is deleted.
It is also recommended to use this recovery method if you have forgotten your device password.
Not everyone knows that you cannot roll back a device to an older version of iOS. Only if you are using the beta version then you have the opportunity to return to the old firmware only within 2 weeks.
Updating with iTunes
If it is not possible to update the operating system using wireless technologies, we recommend flashing the iPad through a computer. This is also one of the most accessible and simplest ways:
- Launch iTunes on your computer.
- Connect your device to your computer using a USB cable.
- In the program, open the main section to find the name of the current operating system. In this case, the next version that can be installed on your device is indicated below.
- Here is the "Update" button, after clicking on which, it remains to wait for the completion of the procedure.
We recommend that you carefully ensure that iPad is placed on a level surface to avoid accidental shutdown. If such a situation occurs during the update process, serious errors in the system and further problems are possible.
But what if the suggested OS version doesn't suit you - how to manually change the iOS version using iTunes? To do this, follow all the steps of the step-by-step instructions:
- Take a close look at the back cover of the tablet - you need to find the exact digital model number.
- Download the required version of the operating system according to the number. There are dozens of file sharing services and other resources for this (download files only from reliable sources).
- Have you downloaded the firmware and has the extension “.zip” in its name? Be sure to rename the file by changing the extension to ".ipsw".
- Launch iTunes on PC.
- Depending on the operating system installed on the computer, press the Shift (for Win) or Alt (for MAC) buttons. As a result, a new window should open with a proposal to download and install the required iPad firmware file yourself.
- The system will check the version and ask for the user's consent to install it via iTunes.
It is recommended to use the same method if you want to test a beta version of a new firmware (that is, not yet officially presented) on your device. Forgot your account id - iTunes has a feature to reset it.
DFU update
There is also a more complicated way to flash an iPad 3 or other gadget model, which is abbreviated as DFU (firmware update). This method is not worth using if you just want to update the tablet operating system, for example, to iOS10. It is recommended to use DFU mode to restore the tablet if it does not turn on due to an incorrect update procedure, freezes occur when Jailbreak is installed, or errors occur directly during the recovery process. If you have no idea how to reflash the iPad in DFU mode, it is worth saying that this method is quite complicated, to successfully complete the procedure, follow the detailed instructions:
- Connect device to PC
- Launch iTunes
- Hold down the power button and turn off the device
- Hold down the power and home buttons at the same time for 10 seconds
- Release the power key, but keep holding Home for about 20 seconds. If a message about connecting a new device appears on the computer, everything worked out
- At the same time, the iPad display should remain black all the time - this is how it happens in DFU mode.
- Further actions do not differ from firmware in Recovery Mode. here you can also select the required firmware version or install the latest available. Keep in mind that data loss is essential when using this method, which is why backups are so important.
Conclusion
Now, knowing how to flash an iPad yourself, you may not take your device to a service center, since such a procedure can be completely carried out on your own. There can be many reasons for flashing: updating the operating system, eliminating errors, restoring the tablet, etc. By carefully following the instructions, any user will be able to complete the procedure quickly and free of charge.
Currently, iPhone is the leader in the global mobile phone market. This is due to its features in service, great capabilities, a variety of functions, options and services provided. This phone can boast of high quality and long years of trouble-free operation. But, nothing in this world lasts forever, including electronic equipment. Over time, the device stops functioning well, and some incomprehensible errors constantly pop up. Quite often, and for no apparent reason, the smartphone restarts. In addition, each user may face a problem when the last update of a personal mobile device was not very successful, or the new version of the operating system did not like it. In this case, the first thing the owner thinks about is how the iPhone firmware of the corresponding version, including 4s, is carried out. We will talk further about how to properly reflash the gadget on our own.
Features of flashing a smartphone
The listed problems make one think and make a choice. Take the iPhone to a service center, where it will be 100% repaired, but you will have to pay a rather large amount for this, or try to find a solution to the problem on your own by simply reflashing the gadget. The service center specialists most often use the same method. There is no need to be afraid to carry out a flashing on your own, since it is not as difficult and long as it seems at first glance.
Flashing an iPhone is restoring the phone to a usable state. You should pay attention to the fact that flashing will lead to the loss of all information from the phone.
Before starting the procedure, if the gadget is in working condition, you need to connect it to a PC and create a backup copy. You should copy personal photos, videos, as well as audio materials to your hard drive, because flashing the device will lead to the fact that it will return to the factory settings and be completely clean.
You should also take into account the fact that regardless of the iPhone variation, be it 3, 4s or 5s, the flashing procedure is carried out identically in all cases. Therefore, you do not need to worry about the discrepancy between the instructions for your phone, you just need to carefully and clearly follow the steps described.
Below, the firmware procedure will be discussed in detail using the example of iPhone 4s.
Preparatory actions
Before starting the operation in question, the subscriber needs to download the firmware with the extension .ipsw. For a specific iPhone model, there is a corresponding version.
Determining which version is needed for a particular smartphone is very easy. The firmware files contain the version of the device (iPhone 3, 4s, 6), as well as its model itself, which is an alphanumeric combination located on the back of the gadget below the logo.
The main difficulty in selecting the firmware version according to the models is that there are GSM and CDMA models of Apple devices. Their difference lies in the fact that these devices function in various cellular networks. The GSM iPhone 4s firmware will not work with the iPhone 4s on CDMA.
After determining the model of your personal device, you need to download the necessary firmware. Each subscriber can pick up the latest version of iOS, or, if he doesn't like it, you can download a slightly outdated one that was on the smartphone earlier. The main condition is that the old version, which is downloaded again, has been signed by Apple.
Also, before the update, the subscriber must turn off the option called "Find iPhone". Otherwise, it will not work to reflash the iPhone 4s, since this function interferes with the procedure in question, therefore, iTunes will knock out an error.
In addition, it is better to once again make sure that the latest version of iTunes is installed on your smartphone, for this you just need to launch the program. If a new version is available, the program will automatically notify you of this and will be able to update. Having completed all the preparatory steps, you can safely proceed to the flashing process itself.
Flashing procedure
In general, to solve the problem under consideration, iPhone 4s owners are offered two options, each of which is absolutely valid, effective, and also allows you to restore your smartphone quite easily and quickly:
- With help
- Via DFUmode.
The first option is emergency recovery mode. It is most often used to restore the functionality of iOS gadgets after the moment when their proper functioning began to malfunction.
The second method does not differ from the first in almost nothing. The only difference is that the procedure is carried out directly using the firmware, bypassing the iPhone operating system. This method is often used when the device is jailbroken or when flashing using the first method is impossible.
Flashing with RecoveryMode
To carry out an operation using this method, the subscriber should turn off the iPhone and wait until the smartphone screen is completely extinguished. Then it needs to be connected to the computer while holding the Home button. The PC will accept the device in RecoveryMode.
Subsequent actions should be performed in this sequence.
It is required to launch the iTunes program and wait for the moment when the program finds the iPhone, there may be two options:
- iTunes will prompt the user to restore the connected device. In this case, click OK.
- iTunes is completely unresponsive. Then you should click on the phone icon, find the item under the name ", after which you need to select it, while holding down the Shift button (if the operating system is Windows) or Alt (when the operating system Mac is used).
Next, the File Manager will open, where the subscriber will need to select the firmware. You need to find the file that contains the firmware downloaded before the start of the operation. Then you need to select it and click the "Open" button.
After that, the program will do everything on its own, you just need to wait for the process to finish. After completion, the device must be disconnected from the computer. Then you need to turn off the phone by holding down the Power button. After that, again pressing the same button, the smartphone must be turned on. That's all, absolutely all iPhone settings have been fixed, and it is ready for further use.
Flashing with DFUmode
Even before the start of the process in question, the smartphone needs to be transferred to DFUmode. Then the phone needs to be connected to the computer and disconnected. After that, on the device, simultaneously hold down the Home and Power buttons and count ten seconds, after which the Power key must be released, and the Home key must be held down until the iTunes program recognizes the customized smartphone in DFU mode.
The subsequent actions must be performed in strict sequence, and they are almost completely identical, as in the case of RecoveryMode:
- First you need to select the required device in the program.
- In the phone management menu, you need to find the item "Restore iPhone".
- After that, it must be selected by pressing the Shift button (if the operating system is Windows) or Alt (when the operating system is Mac).
- In the window that opened as a result, you need to specify the path to the file with the previously downloaded firmware, and then click on the "Open" button.
- After the performed actions, the subscriber needs to wait for the moment when the program will bring the proceeding procedure to the final.
- It remains only to turn on the restored smartphone, after which you can absolutely calmly and confidently use a perfectly working iPhone 4s.
The considered solution to the problem will be useful to those subscribers who installed Jailbreak on their own device, or due to certain reasons, the flashing in RecoveryMode did not lead to success.
Each of the considered flashing options is absolutely valid, and should help solve the problem in question. The subscriber does not need to be afraid to independently carry out this process, since there is nothing complicated about it. You just need to have the slightest skill in using a smartphone and be extremely careful. Actions must be performed in strict sequence, and then a successful ending is guaranteed. The main advantage of the process is that there is no need to spend any money, as if it happened in a service center. Despite this, a person receives a phone with not nearly the worst settings that a gadget service center provides. But if you still doubt your abilities, or for some reason you failed to cope with your goal, then it is better to seek professional help or at least the advice of specialists. This can be done in almost every district of any city in the country.
The beta version of the new operating system from Apple, and then rolling back to iOS 6.1.3, I finally noticed that we still do not have detailed and understandable instructions on our website on iPad firmware... More precisely, there is no instruction whatsoever. This is of course a mess and instructions are still needed, even despite the fact that the firmware of devices from Apple is a very simple process and it starts literally with two mouse clicks (or two finger taps). What you will see now.
For many, the flashing procedure seems complicated due to the fact that there are quite a few ways to flash the iPad. In fact, ordinary users only need two of them. A standard situation - a new iOS has come out and you want to update to it. This can be done through iTunes or through the iPad itself. But in both cases (and in all others too), it is highly advisable to make a backup first, so that if something happens you can restore your data (although in 99.9% of cases you will have everything saved). This is usually done automatically when you connect your iPad to your computer. But if you have old dates in the list of recent copies, you should use the "Create a copy now" button (1).
Pay attention to the "Update" button (2). If you press it, then in a few minutes, if you have fast internet, you will update the firmware of your iPad. It's that simple.
Updating is even easier with the iPad itself. It automatically tracks the appearance of new firmware and signals you about their appearance in this way (3).
Go to the "Software update" section and press the "Download and install" button (4).
In some cases, these two methods are not suitable. For example, you have a very slow internet connection. Or you want to update to a beta version that has not yet been officially released (the same iOS 7 beta 2). In this case, you need to download the firmware file of the appropriate version for your iPad model. If you don't remember your model number, it doesn't matter. You can always see it on the back of your iPad (underlined in red). As you can see, I have an iPad A1458, that is, an iPad with Retina display + Wi-Fi.
The iOS 7 Beta 2 firmware can be downloaded. Just find the one you want by the number in the title.
The latest version for iPad 1 iOS 5.1.1 can be downloaded from the link:
iOS version 6.1.3 for all other iPad models can be downloaded from the following links:
iOS version 7.1.2 for iPhone 4, iPhone 5, iPod touch, iPad 2, iPad 3, iPad 4, iPad Air, iPad mini and iPad mini 2 can be downloaded from the following links:
iOS 9.3 for iPhone 4, iPhone 5, iPhone 6, iPhone 6 Plus, iPod touch, iPad 2, iPad 3, iPad 4, iPad Air, iPad Air 2, iPad Pro, iPad mini, iPad mini 2, iPad mini 3 and iPad mini 4 can be downloaded from the following direct links:
These update methods will suit you 99% of the time. But if you have errors while flashing, or you want to get a "clean" iPad, you can flash it in a special Recovery mode ("Recovery Mode"). In order to get into it, you need to turn off the iPad, then, while holding down the Home button (or, in Russian, the Home button), connect it to your computer. If the iTunes icon and cable image appear on the screen, you did everything right.
After the launch, iTunes itself will greet you with such an inscription.
Here you can simply click "Restore". In this case, the iPad will be reset and the latest official firmware will be installed on the machine.
If you need an iPad just from the factory (let's say you start life anew), feel free to choose "Set up like a new iPad".
And finally, the most serious flashing method is flashing in "DFU-mode" (Device Firmware Upgrade). In it, the iPad is stitched directly, bypassing the operating system. It is recommended if you are having problems even in Recovery mode (although some comrades are always sewn through DFU). To enter this mode:
Connect iPad to Computer
- Close iTunes
- Turn off iPad (for a long time by pressing the power button and moving the "Turn off" slider).
- Hold down the Home and Power buttons for 10 seconds.
- Release the "Power" button, but keep holding "Home" until the computer detects a new USB device (you will hear it "flash"). In time, this will happen in about 10-15 seconds. The iPad screen will be completely black. This is normal and it should be.
- Launch iTunes.
To exit the "DFU-mode", you need to hold down the "Home" and "Power" buttons and hold them until the first signs of iPad life appear.
That's actually all the wisdom. While writing this manual, I reflashed my iPad 4 times. I hope that my work was not in vain and it will be useful to someone, otherwise the instructions on many resources are already outdated. If you have any questions about the firmware, write in the comments, I will try to answer.
Reflashing an iPhone means installing new software in the device. But this procedure does not always mean that the newest product will be installed, sometimes it is required to make an older firmware. Among the fans of smartphones from Apple, there are many who remain faithful to a certain version of iOS. By purchasing a modern iPhone model with the latest operating system, they change it to an older one. Fortunately, this procedure is possible. Like the iPhone 5C and many other models of Apple gadgets, any user who is even a little versed in mobile devices can flash the iPhone 5 on their own.
How to reflash an iPhone 5S yourself, and whether it can be done in different ways, is described in the instructions below. Of course, it is easier to flash an iPhone 5 from specialists by contacting a service center, but today this type of service is quite expensive. Considering that the "fresh" version of iOS comes out almost every year, it is better if you reflash your gadget yourself. Moreover, it is not as difficult as it might seem at first glance.
In total, there are 2 types of iPhone flashing:
Recovery, when the device returns to basic settings and all information stored in memory is deleted. The operating system remains the same, or the version that the user chooses is installed.
An update when the iPhone 5S or other device receives a new version of iOS instead of the previous one, but all data and content on the device is preserved.
It should be noted that the manufacturer did not provide the user with the opportunity to "downgrade" the version of the operating system. For example, when the device has iOS version 7, then it is not possible to return to, say, the fifth version using the usual means. Similarly, it will not work to switch to the latest version of iOS from the beta version.
However, as with any rule, there are exceptions. During the first six months after the release of the new operating system, the owner of the "apple" device has the right to return to one of the earlier versions of the software, if the new one does not suit something. In addition, it can use unofficial products like RedSnOw, but they only work on outdated iPhones.
How to reflash iPhone: preparation
Before flashing a smartphone, you need to carry out a number of preparatory steps for the operation to be successful, namely:
Upload the firmware file to a PC or laptop. Finding a resource where you can do this is very easy - there are many such sites on the network. But the iPhone 5S firmware must meet the following criteria:
- Modifications iPhone 4S, 5S, etc.
- Communication standard. In the process of searching for the firmware file, an attentive user will notice that on the resources where they can be downloaded, they are divided into 2 groups - GSM and CDMA. Here you will need to select the first standard. CDMA gadgets do not have a SIM card tray and this is the easiest way to identify them. The manufacturer decided to block such phones for work with only one communication company, so their price is much lower. But such devices cannot be found in Russia, they can only be purchased in America or China.
- IPhone models. This figure is the alphanumeric character set found on the packaging and on the back of the machine.
Taking into account the above information, the user will definitely not go wrong with the choice of firmware. Of course, if a locked device was purchased, whether it is possible to do a flashing is a question purely for specialists.
Download and install the "fresh" aytyuns utility, if it is not available on your PC. It is better to do this from the official resource of the Apple company.
Lock (disable) the iPhone search function. To do this, go to the icloud settings and deactivate this option. If this is not done, it will not be possible to reflash the device through aytyuns due to an error.
Make a copy of personal information from the phone to another carrier, since during the operation the data may be lost.
Reflashing iPhone via iTunes yourself
This procedure is done through the following steps. The user needs:
- Connect the phone to a PC or laptop (depending on what it works with and where the aytyuns utility is installed). To do this, you need to use the original USB cable.
- Run the utility manually if it did not happen automatically.
- Go to the smartphone control page by clicking on its icon.
- Hold down the shift button, and then the restore button. A window will immediately pop up in which you need to find the previously downloaded firmware. Its format is IPSW . If the utility does not find a file with this format, it will inform the user that the recovery has failed.
- Confirm your decision by clicking on the system update button.
Then the whole process will go automatically. The utility will erase all previous data and install a new operating system. The device will be in Recovery Mode. And its settings will be reset to factory settings.
The user can save time and not search the network for a file with firmware, because it can be entrusted to aytyuns. However, the utility will install on the device a different version of iOS, which is currently installed, and another - the newest one available. If this is what the owner of the "apple" phone needs, at the 4th stage it is necessary to press the iPhone restore button (no buttons on the keyboard need to be pressed).
Jailbreak iPhone Recovery Method
If a jailbreak is installed in the smartphone, you need to do a self-flashing through the DFU mode. This method is also recommended if, for some reason, recovery through the methods presented above failed.
So, to reflash the device in this way, you need to act in accordance with the following instructions:
- Press the home and power buttons, at the same time, and hold down for 10-15 seconds. Then release the power button.
- Connect the gadget to a PC or laptop via the original USB cable.
- As in the previous method, you need to click on the shift and the restore button, select the desired file and download it.
The procedure will automatically start and end, after which you need to take the phone out of DFU mode and wait for the Apple logo to appear on the display.
Methods for updating iPhone
This procedure can be carried out in one of 2 ways: using the aytyuns utility or a wireless WiFi network.
To use the utility and update iOS, you need:
- Connect your smartphone to your PC or laptop.
- Run the utility and enter the iPhone management section.
- Click on the update section (but not restore, as in previous operations).
- If the device already has the latest version of iOS, the utility will inform you about it.
If the user has a ready-made firmware file, do not waste time and wait for Atlus to download it. You need to click on shift, and then on the update button and find the file in the system.
Wait for the end of the process, and then enjoy using the "new" smartphone. All settings and information that were on the device before the update will be saved.
To carry out a similar procedure via WiFi, the user must:
- Activate the control center and click on the wireless icon.
- Go to settings, and then to the WiFi section and connect to any available network.
- Return to the settings, but now to the main ones.
- Go to the software update section.
- Wait until the end of the check for new software. If the utility finds a more "recent" version of iOS than is already installed on the user's device, the display will prompt you to download and install it.
You need to agree with this proposal, and the process will start. In no case should you do an update with a jailbreak, this may lead to a system crash. The device can enter the “eternal apple” state or fall into a loop. The origins of this problem lie in the fact that the jailbreak for new versions of the operating system came out with a significant delay, and when the update is launched, it is done "into the void." To update jailbroken gadgets, the manufacturer recommends using only the iPhone restore button.
Reference. For the first time, the ability to update "apple" devices was implemented on iPhones with iOS 5. Firmware via 2 and 3G connections cannot be performed, tk. Internet speed is too slow.
Thus, owners of non-jailbroken Apple smartphones shouldn't have any problems with self-flashing devices. All user actions in these cases are simple and straightforward. You just need to connect the device to your computer and use the "services" of the aytyuns utility. And those with jailbreak devices need to be more careful. To reset the settings in order to avoid losing the jailbreak, it is better to use specialized software, such as Semi Restore, rather than aytyuns.
