How to Unroot Motorola Moto E and Re-lock the Bootloader

Motorola Moto E is a budget device and will be the first Android smartphone of a large number of buyers (especially in developing countries). After the release of Moto E, there were tons of articles on media sites describing the procedure to Unlock the Bootloader and then finally gaining Root access to the phone’s file system. If for some reason you want to Unroot your Device and re-lock the Bootloader, you must continue reading.

Just Unroot the Motorola Moto E

If you don’t need the root access anymore and want to Unroot your Motorola Moto E (without re-locking the Bootloader), you can easily do that from within the SuperSU app that you flashed onto your phone while rooting.

  1. Open SuperSU
  2. Tap on Settings
  3. Choose Full unroot under Cleanup.Full Unroot option in SuperSU
  4. Tap on Continue.
  5. Wait a few seconds as SuperSU un-registers and removes itself.

Unrooting and Re-locking the Bootloader of Moto E

If you want to also re-lock the bootloader of your Motorola Moto E, you need to flash the stock (factory) firmware onto your phone and then lock back the bootloader. Bootloader is locked only after the phone verifies all files to be original and unchanged. Flashing the factory firmware will also delete all your user data and any apps that you’ve installed. In short, your phone will be returned to the same state as it came when you purchased it.

Re-locking the bootloader does not guarantee a service under warranty. It is up-to the Motorola Authorized Service Centers to acknowledge your warranty or not. But it definitely adds to your chances of getting a service under warranty as they will not be able to detect the previously unlocked bootloader so easily (unless they check the logs)
  1. Download and Install the Motorola Drivers from here
  2. Download the Stock Moto E Firmware from here. Extract it to a particular folder. Make sure that the firmware package that you download should match what is shown in (Settings> About section on your phone)
  3. Download mFastBoot from here and extract it into the same folder where you extracted the firmware.
  4. Turn your phone Off. Press and hold the Volume Down and then press the Power button.You will boot into the fastboot menu.
  5. Connect your phone to your PC via a USB Data Cable and browse to the folder where you extracted your firmware and mfastboot files.
  6. While keeping the shift key pressed, right click on an empty area in the folder and choose Open command window here.
  7. Type or paste the following into the command prompt and press Enter key.
    mfastboot.exe oem lock begin
  8. Now enter the following code to the same command window. The processing should most probably start immediately if you are pasting the code. So you will be needed to press Enter for the last command (erase userdata) after the other processing is complete.
    mfastboot.exe flash partition gpt.bin
    mfastboot.exe flash motoboot motoboot.img
    mfastboot.exe flash logo logo.bin
    mfastboot.exe flash boot boot.img
    mfastboot.exe flash recovery recovery.img
    mfastboot.exe flash system system.img_sparsechunk.0
    mfastboot.exe flash system system.img_sparsechunk.1
    mfastboot.exe flash system system.img_sparsechunk.2
    mfastboot.exe flash modem NON-HLOS.bin
    mfastboot.exe erase modemst1 
    mfastboot.exe erase modemst2 
    mfastboot.exe flash fsg fsg.mbn
    mfastboot.exe erase cache 
    mfastboot.exe erase userdata
  9. Finally enter the following last line of code to finish locking the bootloader of your phone.
    mfastboot.exe oem lock
  10. Reboot your phone.
The above method can also be used if you just want to reset your phone to clean factory state. Or to recover a bricked phone. Whether the phone is unlocked or not, the same command must be used to flash back the stock firmware.
