Hello everyone
I am new here.
I need some assistance with my moto g.
I previously unlocked my Moto G's bootloader but realised that I just wanted it on stock and locked so I didn't damage it, so I managed to relock my
phone's bootloader and got it back to a stock rom.
After installing a system update a few days ago, my phone came back with the
"Warning - bootloader unlocked!" logo after installing a system update.
So I decided to try and reflash the stock firmware and original logo.bin from the XDA Site.
However, my flashes are failing and my moto g is stuck in a bootloop with no rom to boot up to, I have adb minimal fastboot and motorola drivers
/ adb drivers installed.
What happens: I power on the phone into bootloader mode, then I try to flash the ROM I got from droid-developers site, but whenever I try to relock
my bootloader it shows the following:
...
Ready to flash signed images!
OK: (time)
I do fastboot flash partition gpt.bin and I get:
Preflash validation failed!
SST lock failure!
Also trying to issue the command to relock the bootloader gives me
SST lock failure!
I get other errors too when flashing the sparsechunk images, it gives: Invalid PIV signed image! and for motoboot and boot images it gives: Preflash validation failed!
version downgraded for boot.
etc
I cannot recover my stock rom due to these errors, I've searched everywhere (on google) and here and I am desperate to flash the stock rom back and relock bootloader again so I can use the phone.
I am really stuck and my phone will not get out of a bootloop
Any help is really much appreciated as I need to get my phone working so I can use it
You don't need to relock the bootloader. Just follow this tutorial:

I followed the tutorial, but when I get to the flashing stage, I get:
Preflash validation failed,
SST lock failure!
And version downraded for gpt.bin
it seems to be failing to flash these files.
What do I need to do?
You need to provide more information for people to help you. Have you upgraded to 4.4.4?
I had a similar issue when rooting my phone, and all I had to do was unplug the phone from the computer, restart the phone and computer, and then try again.

But did you downgrade from 4.4.4 to 4.4.2?
What model do you have?
Can you explain us all the steps?
Thanks
First unlock your bootloader again. You have to downgrade from 4.4.4 to 4.4.3 then to 4.4.2. During the downgrades you have to follow the same kind of firmware (example: 4.4.4 retail EU -> 4.4.3 retail EU -> 4.4.2 retail EU). When you're done if you want you can relock the bootloader.
HI
I was flashing the GPe image on my XT1033 and while flashing the boot.img and logo.bin i got an error - out of memory , but rest of the parts like system.img etc flashed properly and now my phone won't boot giving me the error "failed to validate boot image'.
I am stuck at the bootloader screen and now neither can i flash some other image since my phone isn't being recognized anymore with cmd showing the message 'waiting for device'
Can someone please provide a solution?
Hello.
I faced the same problems when installing the 4.4.4 br firmware and trying to revert to my original firmware.
This happens because you have a locked bootloader and/or maybe you flashed a wrong boot.bin and you can't reflash boot.img because the bootloader is locked!
What I did is unlock the bootloader and all my problems vanished.. -_- reflash all the files using mfastboot, if it gives you errors on gpt.bin and motoboot.img dont worry and go on with the rest.
Oh, and one strange thing that I luckily figured out, is that to get the device recognized by the PC in the fastboot mode you got to enter fastboot MANUALLY. THat is, press volume down 3 seconds and then power on.
It's gotta say: Fastboot reason: Volume-down key pressed.
If you try to boot and it enters fast boot and gives you the error, for some reason doesn't recognize.
im trying to flash stock 4.4.4 firmware on my XT1032 Retail.en.Us i did everything correctly, everything rturned with an OKAY, when i try to reboot i get a failed to validate boot image and im stuck in fastboot. Does anyone know how to fix this ? i really need help fast. my bootloader is unlocked
Having major issues. The bootloader on this device is locked and I accidentally flashed The wrong firmware. Now I just get a " failed to validate boot img failed" message. Cannot flash anything except for bootloader.img and a few other files in the stock firmware.
Hi i was trying to flash the oos on my device i did some mistake and the device now has no OS and it's stuck in fastboot and when i try to boot the twrp img it shows error that Failed to load/authenticate image and i can't install the rom please help
Well it's Solved i used the StockFirmware guide to unbrick the device but still no recovery was present but also i was able to access adb then so booted the twrp image file and just flashed the oos rom on slot b and it booted into the os. I am now using stock recovery and stock os.
