[Q] Downgrade GT-i9500 to Android 4.1.2
For my employer, I developed an app which needs Android 4.1.2 to be executed. Some employees will be equiped with S4 GT-i9500. I would like to downgrade those phones to Android 4.1.2.
I need to know if S4 GT-i9500 is compatible with Android 4.1.2 and if the downgrade from 4.3 is safe.
Thanks in advance you for your help.
