          You need a unlock key from Motorola, which require your device id and imei number to unlock the bootloader.

            Not all Moto G2 support bootloader unlock. Check your device for that (https://motorola-global-en-uk.custhelp.com/app/answers/detail/a_id/87215)

      Are you flashed the original firmware? Download correct firmware for your model (search on XDA) and flash it. It will solve your issue

        You will need to reflash your phone back to stock firmware or flash TWRP and install a custom ROM image. Before do anything inside your phone, triple check everything.

      It means you have not use the proper key combination to boot into recovery. Alternatively use the adb command to boot into recovery

    • Kannan

      Feb 19, 2016 at 4:43 pm

      Simply unrooting and locking bootloader will not let you install OTA update on your Moto G. TYou have to follow other methods to update your Moto G to Marshmallow.

        hi kannan,
        i need your help on something about moto g 2014 retails version..i have cm13 installed in my phn and want to go back on stock 4.4.4 how can i directly flash the 4.4.4 firmware using twrp. and one more ques. is gapps needed in same ?

        • Kannan

          Apr 21, 2016 at 11:32 am

          If you backed up the stock firmware using TWRP, you can restore it via TWRP. To flash the stock recovery, TWRP recovery is not required. You need to flash it via ADB. Gapps is not needed.

    Hello Mr.Kannan
    I am very new to this world of rooting my android device and such, so please bear with me.
    I own a moto g2, i intended to install Cyanogen so i unlocked the bootloader. After unlocking it, i decided not to put Cyanogen and keep the original ROM.
    Recently i saw an OTA update for the -Stage fright bug fix (something along those lines)- after the installation of the update my moto g2 intended to restarted as you would expect after updating. But however it has been stuck in the : “WARNING BOOTLOADER UNLOCKED etc…” screen ever since.
    Recovery mode does not work since it just says ‘no command’
    Factory reset does nothing except bring it back to the bootloader unlocked screen.
    Please can you give me some advice and assistance.
    If anyone else knows anything that can help me out i welcome it.
    Thank you for your time.

          To get OTA update you need to relock your bootloader.

    • Kannan

      Jun 8, 2015 at 1:26 pm

      Most probably, because you cannot lock its bootloader once it is unlocked

      • Siddharth

        Jul 16, 2015 at 5:06 pm

        Sir, I think there is a command to lock it.

        mfastboot.exe oem lock

        Won’t that work?

        • Kannan

          Jul 16, 2015 at 8:42 pm

          Once you unlock your Moto G 2014 officially, the command will not lock again (that was my experience)

    mfastboot.exe flash system system.img_sparsechunk.0
    mfastboot.exe flash system system.img_sparsechunk.1
    mfastboot.exe flash system system.img_sparsechunk.2
