Yesterday I have upgraded from 4.1.1A using the OTA download, but after the phone rebooted and selected Update Firmware, I got “Firmware is corrupted”. After that, I have tried to clear data multiple times, but the phone keeps restarting continuously, like it has a timer or something after 10-20 seconds after restart.
In the meantime I downloaded the full 4.1.2A ROM, but I cannot copy it in the phone, since the phone reboots very quickly.
In recovery mode I don’t have access to the main partition when I connect the USB cable.
I also tried in fast-boot mode to flash the full ROM, but doesn’t work.
Does anyone know if there is a way to fix it (except sending it back to Meizu)?
