hi guys have made an absolute mess of this
heres what i did manged to install TWRP / Superu / unlock bootloader and root the phone with no issues
decided i wanted to go back to stock so via TWRP i flashed the stock image
that left me at stock - BUT bootloader still locked
so I went in and enabled USB debugging and FORGOT to tick the allow oem lock option
did an mfastboot oem lock - and it said success
then i did fastboot reboot - this where it failed
saying "boot up failed - failed to validate system image
but it was the corrrect image as of this thread
http://forum.xda-developers.com/mot...dows-tool-moto-g-2015-xt1072-restore-t3124915
Am stuck in that screen with options Normal Powerup/ REcovery / Factory / Barcodes / BP Tools
Currently it says "failed to validate system image"
and on next line
"Fastboot Reason: Fall-through from normal boot mode"
!00% my own fault for not being careful -
are there any utilities / batch files / tips or tricks
that can get me back on the road to stock firmware again ?

Just unlock it... There's no point of locking it again.

Hi Luk
the problem is that i DID NOT set the option for "Allow OEM UnLock"
and it will not unlock for me
its says (bootloader) - Check Allow OEM Unlock
it says FAILED (Remote failure)
Please help
long story short, my relative came to me for help after he decided to install a new ROM and made a simple error of forgetting about the OEM unlock option in the settings menu beforehand. an error occurred along the way and he tried to go back to stock. now when the phone boots it goes into the bootloader (which is locked) and gives a start up failed message saying to use Software Repair Assistant.
trying to go into recovery gives a
Code:
AP Fastboot Flash Mode [Secure]
Fastboot Reason: UTAG *bootmode* configured as fastboot
failed to validate system image
ERROR : Failed to pass validation. backup to fastboot
Boot up failed
i tried flashing TWRP but its giving errors too. are there any known workarounds to unlocking the bootloader or forcing a recovery/twrp to work?
thanks, all
Hi guys, I buyed a phone used phone with this problem. The original owner tryed to flash a custom rom and at the middle of the progress the phone shut down because low battery. Then, when they turned on the phone, it only boot in fastboot mode. In fastboot mode, Recovery option wont open, Normal boot wont open too. The bootloader is unlocked. Then, i tryed to flsah a 5.0.2 stock rom but the console show me up an error like "FAILED" or "bootloader FAILED" The phone shows "recovery downgrade" in purple. I tryed 6.0.0 too and Kit Kat for the XT1064 USA version. I cant flash nothing, always the same error. i installed Motorola drivers, ADB, etc. Any help?
Bootloader version is: 48.07. I serarched this number in google and it shows a 5.1.1 custom rom. Propably this rom was the same that he tryed to flash before, i dont know. Unlocked status also is 3.
Edit 1: When a choose "Normal boot" it says: Invalid boot Image Header! Fastboot reason: Fall-Through from recovery boot mode.
When i choose "Recovery" it says: Invalid boot Image Header
boot up failed
When i choose "Factory": The phone just restarts into fastboot again...
Checking Motorola Device Update, the firmware inside this phone is: 21.11.17.titan.retuaws.retuaws.en.us what it means, it have android 5.0.2 Lollipop, right?
Hope you can help me
Thanks.
