How to Unbrick a Bricked Moto G4 Plus

1. Install Motorola driver and connect your Moto G4 Plus to your PC. Under Device Manger, your device should be detected as QualcommLoader or something like that.

2. Unzip the BlankFlash zip file you have downloaded and save the content inside the ADB installation directory.

3. Run ‘Blank-Flash.bat’ file. A command window will be open and it will flash some files to your phone. After few seconds, your Phone will reboot to Fastboot mode (First sign of life!)

4. Now, unzip the Bootloader and GPT files you have saved and save the content inside the ADB installation directory.

5. Inside ADB folder, open a command window (Press Shift key, right click and select ‘open command window here’ menu) and issue below commands.

fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader

Note: Once done, you will see the Fastboot mode on your screen. You are now ready to flash stock firmware on it, but you just can’t flash older ROM (cannot downgrade), otherwise will brick your device again.

      If you can boot into stock recovery, try installing stock ROM.

      Once unlocked the bootloader, probably you will not be able to install the OTA update. Also, relocking the bootloader will not help.
