[Moto G 2014 LTE Q&A, Help & Troubleshooting] enricocava:
Hi all,

I had a XT1072 with Android 6 and wanted to go back to 5 due to problems with GPS.

I unlocked the boot loader, flashed stock ROM with Android 6 and all was fine.

I next tried to flash stock ROM with Android 5 and was stuck in fast boot with errors like "invalid system image signature" or similar.

Next I messed around with TWRP, stock again, lock, unlock... a mess.

Now it's stuck in fastboot with status "LOCKED, status code 2" (0 is LOCKED, 3 UNLOCKED, 2 what is it?)

I tried flashing stock ROM both 5 and 6 in different versions:

RETDEALL_XT1072_5.0.2_LXB22.46-28_cid7_subsidy-DEFAULT_CFC.xml

RETESALL_XT1072_5.0.2_LXB22.46-28_cid7_subsidy-DEFAULT_CFC.xml

RETGBALL_XT1072_5.0.2_LXB22.46-28_cid7_subsidy-DEFAULT_CFC.xml

RETGBALL_XT1072_5.0.2_LXB22.99-24_cid7_subsidy-DEFAULT_CFC.xml

RETGBALL_XT1072_5.0.2_LXB22.99-24_cid7_subsidy-DEFAULT_CFC.xml

Motorola_Moto_G2_XT1072_MPB24.65-34_CID12_6.0

But all fail with "failed validation";

Unlock fails, but I cannot boot in Android to change mentioned option:

mfastboot-v2> .\mfastboot oem unlock XSVDURWNGOWYDFMGU5ZT
...
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
finished. total time: 0.057s

RSD Lite to flash stock ROM doesn't see my device.

Rescue and Smart Assistant cannot proceed due to "missing version-baseband:" (see empty var listed below).

Do you have any suggestions to restore it?

Let me know if I can give you more information.

Thanks
