Hi guys,
actually I have the Version ALE-L21C55B160 installed on my device. I would like to downgrade to another version because this version is branded (TIM Italy).
I downloaded the Stock firmware from this thread, copied it to the sd card (in the dload folder) and tried to upgrade/downgrade the firmware. I get immediately the Error "Software install failed!".
I tried via the EMUI Upgrader and via Power+VolumeUp+VolumeDown Key but without success.
Somebody has a suggestion? I don't want to unlock the bootloader or root the phone (company phone).
Thx in advanced!
