  1. do not flash gpt.bin and bootloader.img/motoboot.img files. this lines made mt day, thanks brother 🙂

    1. Hi. You’re welcome!

      Those two files hold immense importance. Flashing an older gpt.bin (partition table) or an older motoboot.img (bootloader) can potentially brick the phone, mostly beyond self-recovery. I have gone through this mishap back with Moto E 1st Gen, and it taught me a lesson; to not miss any details when meddling with anything.

      Most novice users nowadays think that processes like rooting, unlocking the bootloader, flashing ROMs, and even restoring stock firmware, is quite easy. However, they forget the details, the processes may vary from manufacturer to manufacturer, sometimes even different between devices from the same manufacturer.

  2. Hi,
    I have a moto G5 S plus which suddenly entered in a boot loop last month.At first I tried to factory reset my phone through boot loader but it didn’t work out.I then unlocked my phone and tried to flash a custom ROM through TWRP.I followed the exact process by wiping the partions and then tried flashing the Rom.I did not take any backup of the files. The flashing didn’t work I repeatedly got the error 7.I Google for solution it asked me to use the latest TWRP software and to delete the asserts.I did exactly what it asked me to do.I still keep getting the same error over and over again.I even tried flashing other ROMs and even stock rom. It won’t work.Can you please tell me why is this happing and I wanna try the above process I understood every step but how would I know how may system.img_sparsechunk files my device has and how may should I write in the command.please help!

  3. Please tell me what to do in order to relpck the bootloader. I unlocked my phone and now i am having some glitches and bugs with power and network. So i would like to relock the bootloader. I know i hv to flash the custom rom but then next what to do?

    Please yell tell me.

    Thanks for your help on this topic. I couldn’t find this anywhere else on the internet.

    1. Hi Ansh. Unlocking the bootloader has nothing to do with the software-related bugs. It’s just like a hardware switch that has no relation with the software’s performance whatsoever.

      As for unlocking the bootloader on Motorola phones, I think it is not possible. Instead of that, I would suggest you take a full backup of all the data including internal storage and then flash the latest stock firmware available for your phone.

      And don’t worry, an unlocked bootloader would not affect your phone’s ability to receive OTA updates in future.

  4. fastboot flash partition gpt.bin
    target reported max download size of 536870912 bytes
    sending ‘partition’ (45 KB)…
    OKAY [ 0.005s]
    writing ‘partition’…
    (bootloader) Validating ‘gpt.default.xml’
    (bootloader) Security version downgrade
    (bootloader) Image primary_gpt failed validation
    (bootloader) Preflash validation failed
    (bootloader) Cancelling ‘gpt.default.xml’
    FAILED (remote failure)
    finished. total time: 0.082s

    1. Please avoid GPT.bin if you’re flashing a lower firmware. It might brick your device beyond recovery.
