      Locked boot loader, can't unlock due to "Allow OEM Unlock" not being checked. Now can't flash any gpt partition files or system images.

      Pls Help me if the problem is resolved..

  6. Man, I just unlocked the bookloader and my phone got on normally and bootloader is unlocked.
    Now i installed TWRP.

    Til here everything is okay, but as soon as i tried to reboot in system through TWRP it asked me to root my device, so i swiped and rooted it and from that moment my phone is hanged on that bootleader screen which says "WARNING BOOTLOADER UNLOCKED".

    Please let me know if by flashing stock firmware will my problem be solved?
    BTW I'm having Indian XT1550 model of G3.

  8. I rooted my moto g 2015 xt1550(osprey) and tried few Custom ROM's.
    Then I switched back to stock rom to marshmallow with the help of the file which was provided by lost101 . I did exactly how it was written every thing went well, my cell booted normally. Then I replaced the recovery by TWRP file. After that I installed SuperSU file from TWRP and when i restarted in system it got stuck on boot loop.
    1. I tried installing ROM again and TWRP that time it started well but as i install SuperSU it gets stuck
    2. When i install TWRP and just boot after some time wen i try switching to TWRP it says no command.

    PLZ help i really want my root privileges back. I am unable to understand how to resolve this.

  9. I min a bootloop or my device is bricked.
    When I flash commands it says
    Preflash validation failed
    FAILED .
    I ignored and started putting next command at the end my device powered off but not rebooted.
    Please help me to prevent preflash validation… Please help me I am in a really bad situation.
    Thanks .

  10. This is what I got. please help

      What am I doing wrong?

  14. I'm facing some different problem, i got OTA update for android 6.0 on moto g3 (xt1550) i installed it and my phone is stuck in bootloop, then i tried your method, again and again i'm flashing android 6.0 but everytime it stuck in bootloop.
    I cant even unlock bootloader because usb debugging is disabled so can you tell me is there any other way to flash stock rom without getting into bootloop. THANK-YOU…

  15. Right now I am using cm12.1, thinking of switching to stock 6.0 Now, i wanted to know 1) whether i will get future OTAs after flashing stock 6.0 and 2)which recovery it will be after flashing stock twrp or stock ?

  17. I DID ALL THE STEP U SAID NO ERROR FOUND IN ANY STEP BUT STILL MY MOBILE IS NOT BOOTING. ERROR IS "FAILED TO VALIDATE SYSTEM IMAGE, ERRROR FAILED TO PASS VALIDATON, BACKUP TO FASTBOOT"
    FASTBOOT REASON: FALL-THROUGH FROM NORMAL BOOT MODE

    • It's weird to say but, yesterday I was using "kingroot", after an hour of doing some processes, my Moto G 2015 with 1gb ram, 16gb and dual-sim started to restart. Few minutes before that, I could see that the phone was to slow, so I decided to restart it. Due to that as I said my Moto G3 started to restart but there were two problems. My net and my wi-fi are not working. This morning I decided to hard reset, everything was okay. No bootloop or brick, but my net and wi-fi still not working.
      I don't know what to do. I'll try to install stock rom lollipop and see what happens

  18. Awesome! Worked perfectly. Although i had to change the commands to lowercase as it didn’t recognize them in uppercase. Thanks 🙂

  19. Hey there, my phone still looking better with these steps, but hen it boots its still stock on the “warning bootloader unlocked” and then it says “erasing…” and it loops these two messages?

    do you know what should I do?

    Thank you very much for any help!!

  20. I’m having trouble unlocking my bike g3 xt1541 8g rom because I found all pack are not 2016 and can enable developer mode
    I need to find the rom that is to pack 2015

  21. Thank you!

    The gpt.bin step didn’t work. But the rest of your steps got me out of bootloader loop and back to the way my Moto G 3rd Gen was when I bought it.

    I had to tried to root it. I unlocked the phone and installed TWRP successfully but SuperSU broke my phone somehow.

  22. bro u are like god to me my phone was stuch at bootloop and i tried it in your way and it worked and please tell can we install OTA updates now
