I was run lollipop custom Stock rom Optimized (root, etc) and have trwp recovery.
Every things works fine and I use the fone about 1 week and today the phone turn automatically on bootloader screen.
I was unable to boot proprely on Normal Powerup and go to recovery.
error message: failed to validate recovery image - boot up failed
I then try to flash stock firmaware and I go these error:

What version of TWRP are you running? Some of the older ones aren't supported anymore and have trouble flashing on the Moto G 2014. You should be using v2.8.5.0

It looks like the partition tables have been completely removed because the "failed to write primary gpt is a Linux error". Since none of the commands will access the partitions, I would guess the partitions need to be rebuilt. I don't have a clue how to do that on a mobile though.

[Q] Help: Device locked: 5.1 fastboot flash fails

I have a Moto-maker-made Moto X with T-mobile sim (I think XT1053) and never installed any custom ROMs. The soak from couple weeks ago soft-bricked the phone (factory reset from fastboot menu just powers off the phone). I can get into fastboot, but the device is locked (status code 0). Do I have to unlock it in order to apply the factory image? The steps below fail currently.
I got the TMO_Retail_XT1053_5.1_LPA23.12-15.222.21.15.ghost_row.Retail.en.US.tgz from motorola, and ran all fastboot steps until "fastboot flash boot boot.img" which failed:

Well you can't Flash the retail firmware on that device. You need to flash the exact same firmware that was on the device before you bricked it. You can definitely use ADB and fastboot if you can get the phone into fastboot mode.
it's failing because you're trying to install an older firmware than the one you have. You're lucky it did not succeed flashing the GPT. That is the partition index. if you had successfully flash that and the bootloader from an older firmware than what you had you would have a hard brick on your hands with no chance of recovering it without a blank flash file.
Run
Fastboot getvar
To see what version of the software you have on your device. then use fastboot to flash the same or a newer version that is correct for your device.
Look here

Try cricket or att

Hello and thanks for answering, yes i use this rom https://mirrors.lolinet.com/firmwar...ubsidy-CRICKET_regulatory-DEFAULT_CFC.xml.zip to restore my phoen but no luck, and retus rom the problem started but i see this rom is for moto g(6) play, i don´t know if cricket has another rom , my moto g6 forge has jeter OCP27.91-42 and I can not find that rom anywhere.
I have reviewed and donwloaded the att, retus and cricket but internally (3 roms) all are for moto g(6) play and tried with fastboot both with the same error result.
I've seen on Youtube a person who has moto G6 Forge with rom motorola/ jeter_a/jeter 8.0.0 /ocp27.91.41/43 and i think all the roms for this model should be the same but I can not find this rom.
sorry for my english i hope it is understood, any idea?

i have this with fastboot getvar all:

You may have yours updated to a build version that hasn't been released yet for download. I can't really help with that. You're supposed to check for a download of your current firmware before trying to flash anything. you're probably going to have to just wait until that firmware is either posted here in the Forum or uploaded to that website.

You are right, I thought that it was rom of my phone. It was the update of my phone and that with the retus I could return to retail but apparently I am still learning.
maybe someone upload the rom or I'll wait for it to be published, like you say.
pd. if it possible that make a rom with other moto g6 forge without root and install with fastboot with the bad moto g6 forge
Thank you,

today with XT1922-9_JETER_A_CRICKET_8.0.0_OCPS27.91-62-7_cid1_subsidy-CRICKET_regulatory-DEFAULT_CFC.xml my phone works again
i have a question, how can I do to unlock my moto g6 forge and use other sim?
I have tried to unlock (by code) it with 2 companies but they can not

What commands do I need to put when I flash the rom? Thank you

Use the commands in the file. You can use RSDlite with a Windows PC and it will flash it all for you. Or use RSDlite XML to batch to convert it to a .bat file for one click in fastboot. It converts it to a batch file to perform that flashes for you.
If you want to wipe data and start fresh, choose the flashfile.xml in the firmware. If you want to try to keep data, use the servicefile.xml.
If you are using official firmware, you don't need the bootloader unlocked
Find the tools here
Use RSDlite 6.2.4
works fine on windows 10.
Great tools on that page.
Get firmware from https.mirrors.lolinet.com

It looks like I'm in a similar situation. Today I went to upgrade my Cricket Moto G6 Play (XT1922-9) to Android Pie, which is available for the XT1922-9 but only for the RETUS channel. I ran the batch file in fastboot and received the "Preflash validation failed" on the boot, recovery and system partitions. Now the device only boots to the bootloader because it fails to validate the boot image. Likewise, recovery mode is inaccessible because it can't validate the recovery image. (Interestingly enough, neither of these images were actually flashed.)
Now the locked device seems completely bricked. Motorola wouldn't allow me to unlock the bootloader, and trying to flash the latest Oreo ROM for the Cricket channel also fails validation. (I had OCPS27.91-62-10 installed, but that doesn't seem to be available for download. I tried OCPS27.91-62-19.)
So am I really stuck on the bootloader with no inability to flash known-good (and properly signed) OEM firmware? How can Motorola create a system that's so fragile?

I've checked lots of other posts here, but none of them worked for me.
I've installed a somewhat quirky custom ROM (Pixel experience 12) on my Moto G5S Plus, and now I can't get into TWRP, because it bootloops.
When I try to erase/format any partition that might solve the problem from fastboot, I get:

Also, the custom ROM is working fine, the only problem is TWRP not starting.
Do you guys have any clue on how to solve this?

Made a mistake trying to flash my XT2041-4

I followed steps to install the original build onto my g power and wiped the partition but then the flashing the bootloader failed. Now I can see I needed to unlock the bootloader first and I had not done that. I wiped the partition. I can get the phone into fastboot and that is it. Trying to go into recovery mode fails with "No valid operating system could be found. The device will not boot."
My device is the XT2041-4 and I was intending to revert back to Android 10 and now I'm stuck. I'm not sure how to unlock the bootloader. What can I do to recover? Or is there a way to get a build back on it?
Code:

Dang, I got a code to unlock the bootloader but I didn't enable a setting before wiping the partition. Any tips?
