After flashing to the wrong stock (used a US one instead of a Tesco GB one) using a premade program, I am flashing to the Tesco GB Moto G stock .
When I enter "fastboot flash partition gpt.bin" it comes up with:
Code:
C:\Users\Ryan\Desktop\tesco>fastboot flash partition gpt.bin
target reported max download size of 536870912 bytes
sending 'partition' (32 KB)...
OKAY [ 0.102s]
writing 'partition'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.461s
How could I resolve this error?
Thanks.
Got the same error here, (also trying to go back to tesco) did you manage to resolve this?
The most likely cause is due to your Bootloader being locked.

Hi! i've been a long time lurker of the site for a couple of years now, I've happily been able to solve almost all of my problems just by searching the forums. but know I have no idea what to do, so i made an account and see if anyone has any insight on this
Here's the rundown:
recently bought a used moto g and started playing around with it and when i tried to upgrade the firmware manually. i kinda bricked it.
right now it's stuck on the bootloader screen (the one with AP fastboot flash mode (S))
my device is locked, from what i understand this particular model of moto g, the AIO wireless one, can't be bootloader unlocked.
i tried flashing US_retail_XT1032_KXB21.14-L1.32_CFC using the guide on [GUIDE] Moto G - Restore stock firmware
mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot flash logo logo.bin
those commands worked correctly, but the next one,
mfastboot flash boot boot.img gives me the following error
target max-sparse-size: 256MB
sending 'boot' (10240 KB)...
OKAY [ 0.354s]
writing 'boot'...
(bootloader) Preflash validation
FAILED (remote failure)
finished. total time: 0.850s
On the phone it says "hab check failed for boot"
after about an hour of research i was able to figure out which firmware was the original one, using the getvar all command, and it gives me this one
motorola/falcon_aio/falcon_umts:4.
4.2/KXB20.9-1.10-1.9/12:user/bldac
fg,release-keys
: Blur_Version.173.44.9.falcon_umts
: .AIO.en.US
now i was able to get that firmware after a while, and i tried to reflash it to the phone, but now i get these errors
mfastboot flash partition gpt.bin
target max-sparse-size: 256MB
sending 'partition' (32 KB)...
OKAY [ 0.071s]
writing 'partition'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.458s
on the phone it says "version downgraded for primary_gpt"
on the next command i get this

target max-sparse-size: 256MB
sending 'motoboot' (1940 KB)...
OKAY [ 0.147s]
writing 'motoboot'...
(bootloader) Motoboot: Preflash validation for tz
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.493s
and on the phone it says "version downgraded for tz"
the logo flashes fine , but boot gives me another error

OKAY [ 0.401s]
writing 'boot'...

and the phone says "version downgraded for boot"
now ive tried pretty much all the 4.4.2 retail US and 4.4.3 retail US firmwares and i get the same errors, or a combination of them
i have no idea what to do now, and i cant seem to find a 4..4.3 firmware for AIO wireless, and there does not seem to be one
does anybody has some information to signal me in the right direction? i'm afraid i just bricked it, and i barely even used it lol
I recently flashed my Moto G to stock android from a custom ROM, and now my device does not fully boot up. After showing the boot animation it just shows "starting services" for about a minute then shuts itself off. Whenever I try to reinstall the ROM and flash the partition, this is what it tells me
C:\Users\Kyle\Desktop\AndroidSDK\adt-bundle-windows-x86_64-20131030\sdk\platform-tools>mfastboot flash partition gpt.bin

Is there any way this can be fixed or is my device potentially bricked? Any help would be appreciated

Flash stock rom, then you can flash custom recovery and custom rom
I have a bootloader unlocked XT1032 MOTO G on UK EE network. I have been trying to flash stock 4.4.4 (so that I can upgrade to OTA lollipop) but am getting a 'Preflash validation failed error'.
I've tried various things to get it to flash the images but nothing has worked.
Can anyone suggest how I might get this work?

Just skip flashing the gpt.bin and motoboot.img but flash the rest. The phone should still work.

Thanks for the suggestion, however there's others that fail too:
boot.img won't flash
Recovery does flash but I get the broken android with 'No command' message when trying to boot to recovery
System images won't flash

It will still boot normally after that. Any ideas?
Crazy question but are you sure you are flashing the correct rom for your phone? Was it on gpe before?

I'm pretty sure I am. I did try and convert to GPE using the AIO tool (when trying to resolve the issues) but I've seen nothing to suggest this has actually worked.
The phone has previously been rooted, but isn't currently.
System version is showing as:
210.12.40.falcon_umts.EESL.en.GB
Build number:
KXB21.14-L1.40
Kernel version:
3.4.42-gb89c9dd

Update for lollipop in moto G Don´t work, ota Says "Updated"
HELP..
Same problem here preflash validation failed for Logo, GPT and Motoboot
(Downgrade from Lollipop 5.1 (XD1039 RETBR) To Kitkat 4.4.4
BOOOTLOADER is Unlocked.
Dear all,
I own a XT1541 and updated to Marhsmallow via OTA few weeks ago. I encountered some troubles with the performance. I also had the issue that a single app was attempted to be optimized on every boot. Therefore, I decided to reset it to factory settings. However, it seemed that this process failed (waited nearly for an hour to complete but nothing happened).
After rebooting then manually, I am stuck in a fastboot message
AP Fastboot Flash Mode (Secure)
failed to validate boot image
ERROR: failed to pass validation, backup to fastboot
Fastboot Reason: Fall-through from charger boot mode
CID Read Failure
Invalid CID status 0x69
I can access the device via my Linux using fastboot command. What do you propose to recover from my problem.
Thanks

One thing that confuses me is the fact that the tool tells me that I shall turn on the USB debug mode. However, since Android does not boot any longer, I have no chance to do this in the Settings. Is there any way to enable this debug mode in another way?
OK I HAVE A MOTO G3 , SKU=XT1541 , VER=P2B , BUILD MP.124.107.55 , SYS VERS=24.61.55OSPREY
It is an unlocked euro version with 1gb ram , i.e not locked to any carrier or ever has been.
I was able to unlock the bootloader , I then followed very carefully the instructions on this site to get the image , usb drivers and everthing required.
However once ono entering the commands at the dos window to start flashing a new rom it comes back with an error , I think I have the incorrect image or there is not one on this site.
I am a complete nuubie can anyone help me please.
