Hi there, i unlocked the bootloader of my Moto G 2015 XT1540 to play with it and install custom ROMs, but now i want to relock it because i want to gift it to my mother.
I've tried several tutorials about it but it fails. (I used XT1540_OSPREY_RETUS_2GB_6.0_MPI24.65-25.1_cid9 firmware from the index on XDA).

The build you're flashing is older than the one that's installed on the phone. That's why you are getting the 'preflash validation failure' message.
Also, I don't see the need to lock the bootloader even if you are giving it to someone else. Just flash the stock firmware. Skip the bootloader and gpt files, flash everything else.
Actually, you are doing this completely wrong... You don't mix oem commands (lock begin and fb_mode_set are exclusive of each other, at least I have never seen a guide that uses them together, so it's deduction), but that isn't your core problem... @adityak1303 hit on that, you are getting "preflash validation errors" which generally means the pieces you are flashing are older than is what is installed. Very common actually since we do not have the latest factory images currently. The kicker here is although you can likely get it functional again, you can't lock the bootloader without being able to flash each piece of a complete ROM image, which you can't do without having a newer image, meaning ALL pieces, you must flash gpt.bin and bootloader, and every piece to relock.
Why the urge to relock? You know it will never go back to the way it was, you will still have to use the modified logo.bin to cover the unlock warning page (that never goes away) and the bootloader and getvar will always show it has been unlocked... There is no point except pure security to relock the bootloader, but you will still know it was once unlocked.
Thanks for your help, I flashed stock ROM (without gpt.bin and bootloader.bin), custom logo.bin and yep it works also I got the January OTA.

Good day everyone, I got a moto g bricked I assume because whenever y restart it when it gets past the moto logo yt just stays in a black screen, tried to use recovery but whenever y do it says boot up failed. Read somewhere that this can only be used when the phone is unlocked, tried to do it following moto's homepage instructions but after I use the key they provide me it doesnt unlock it, on fastboot it keeps saying its locked eventhough on the terminal it says succesfully unlocked.
Was thinking to flash a stock rom but I dont know wich model this moto g is and what android version it was, any suggestions are appreciated, really new with dealing with moto so I dont even know if theres a flashing tool for this tried searching for it and didnt find it.
Thanks a lot, regards.
Edit: I just found how to flash images , used a us stock rom and when Im trying to use fastboot it gives me several errors

Plese tell me what i have to do now ?
Thankyou
I unlocked mine to get this working so I don't think you have much choice. But I'm glad I did it: Marshmallow was a mess on my G3.
Hi,
I recieved a sms with a question, "is this you phone", as i was replying my phone rebooted.
Then my moto G XT1032 was hanging on the android startup screen.
I dicided to do a recovery.
It did not work,it got stuck on the erase of user data part.
Then I dicided to flash the moto G with XT1032_FALCON_RETEU_5.1_LPB23.13-56_cid7_CFC.xml.
Al went well until i got to the part "fastboot flash system.img_sparsechunk.1, 2 and 3" there i got an acces denied message.
The device rebooted.
After the reboot te only thing i get is a flashing dead android guy.
What should i do or what can i do next.
Greetings
zzoemie

Hi,
How can i do that with a blinking dead android guy laying on his side on my screen.
OK, can you switch the phone off? Just press and hold the power button. If it worked, then you have to press and hold the power button and volume down button for 3 seconds and then let go.
Yes, but when it restarts the blinking guy is back.
Wat should i do when i AM in the bootloader? I'm a newbe.
Install log and errors
I can't unlock the bootloader.
Below you find the install log.
So bootloader permissions are denied.
Help, anyone.

ok This is what I did.
Go Motorola Moto G 3rd Gen. Android 5.0.1, than I download the KingRoot App, to uninstall some bloadware apps. was fine. than few days ago, I updated Motorola to Android 6. Next day I watched some youtube videos and it went to hard reset mode. Since than I can do nothing. Cant unlock the boot loader even with the code from Motorola. Cant flash it just nothing. Im out of ideas. Would like to take a hammer and just smash it. Please someone help me. And I cant turn on the developer mode. take a look on the error which I get, over and over and over again.

Thank you for your Info. never thought that it would be so quick here. So yesterday I downloaded android 6, did the flashing again. and it works fine now.
So for all the other Motorola Moto G 3rd generations users.
When you root the phone in Android 5, and you update it with official OTA Android 6, don't root the phone again with some App like KingRoot, as the phone OS might be bricked. Also to flash the Motorola, in that status which I got. You don't need the boot loader unlocking code from Motorola, eather you don't need to activate developer mode. Just download Android 6, and flash it. FASTBOOT DEVICES - code to be sure your phone is recognize it by your PC.
Thanks again to the XDA people and (therealduff1) which help me very quick
Hi There,
I hope someone can advise and possibly provide help resolving this problem.
The Moto G4 XT1622 is not able to boot to OS, It only boots into bootloader, cannot go into recovery and cannot go into Factory Mode etc.
The error i get on the phone is....

ERROR: Failed to pass validation, backup to fastboot
Fastboot Reason: Fall-through from normal boot mode
I have tried to clear fb_mode and tried to unlock the bootloader without success.
I have tried various stock roms to get this fixed. The phone has never been unlocked and not been rooted.

It looks to me like you're trying to flash a firmware that is a downgrade from what was already on the device. It's probably blocking you because it won't allow a downgrade. Flash the version that the device already had on it or flash a newer version.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE
I throught that would be the case but i have tried the 4 roms available for this device and even the 7.0 OTA rom but nothing if able to flash. I cannot even unlock the bootloader.
Thanks

You may have to faatboot flash the individual .img(boot, system, cache, recovery, etc..) files by themselves.

Do you have USB debugging enabled?

Hi,
I dont think so as I cannot check due to the phone not able to get pass bootloader. I tried to use the fb_mode command but still goes back to bootloader saying filed to start.
Thanks..
