Only for unlocked Bootloader
For anyone interested in going back to Stock/Original English Firmware with fixed OTA.
Just run AUTO INSTALL.bat and relax while the Firmware gets flashed.
If you have bugs or note a bad behavior, do a factory reset after installing the Firmware.
There is a typo in the installer script, so please use this .bat file instead of the original: https://mega.nz/#!MlwmBQRA!xre2zimVd...6WqS1oewVygPs8
