Similar problems for two reasons occur: either the new version of the firmware has become available to users in too raw form, with errors in code and flaws, or the device that has been updated has been able to endure for the loads created by the new version of IOS.

Note that the rollback of any device for any version is not possible, detailed information about which device to which firmware version can be returned, you can view the next site - http://appstudio.org/shsh. All data are located in the table format.
