Hello!
I have a problem with my moto g3, he gets stuck at fastboot screen at gives error "version downgraded for boot, failed to validate boot image" after an ota update.
I've tried with different factory ROMs and everyone of them says error "(bootloader) Preflash validation failed
FAILED (remote failure)"
What can I do? My phone won't work ever o there's a solution?, I've tried and I couldn't get it to flash anything.
I can't get it to claim warranty nor do I believe there's a specialized motorola service where I live.
Thanks in advance.

What did you do to it before this occurred? try to flash lollipop?
what model number, country, carrier; what was the last working rom you had on it.
Have you done this?

Thanks for answering friend.
Is an XT1540. US retail. Unlocked. It had 6.0 before the ota that i think ir was a security update because it was aprox. 300mb.
Yes, i tried that with several images (factory) it wont ley me flash anything, gives me the errors that i mentioned before when i tried to flash gpt, system an recovery, it only flash logo.bin, nhlos succesfully.
I've tried to flash the 6.0 image corresponding to my model(xt1540 RETUS 2GB).
It says in the fastboot "invalid PIV image" and un the cmd "invalid signed image" or something like that.
You think is solvable?
Thanks a lot.
what twrp have you flashed?
No one, bootloader's locked, therefore i couldn't flash either twrp nor custom roms.
I suppose it had factory recovery, but it i choose to go to the recovery, il'll loop and go to the fastboot screen. I can only acces to the fastboot and fastboot logs.
Hang on a few minutes I'm working on a new guide...
If you do, i guess ill have to buy some marble to stand a statue un you honor man, thanks.
plastic's fine.
Start at the beginning and alert me if there's any confusion so I can fix it. Thanks.

Friend, it's pretty clear. Le probleme est that i dont hace and unlocked bootloader, but un order to unlock it i hace to check the box un developer options and i cannot do that cuz im stuck un bootloader mode, is a vicious circle, do you get me?
Can you boot to stock recovery - same as with TWRP but you will get a luing down android - press vol-up and after a few secs you will be in stock recovery. Do a factory reset. Maybe then you can boot. If not I am out of ideas.
It wont ley me boot to recovery, i ve done several factory reset vía fastboot mode.
Thanks forma taking the time trying to help me, i appreciate that.
you're welcome!

okay, thinking more on this - since you can do fastboot factory reset, can you do a fastboot flash recovery? - show me a pic of the commands and results when you try it. Grab squid's latest and see what happens. Or will it just block it because you're locked.
haven't had a chance to look fully at this. Most need recovery, but...

Hey, you came back!! Haha.
Well, trying to flash anything will give me the error "failed remote failure" and "preflash valiudation failed", I've tried to flash either factory recoveries and TWRP with the same result. Addtionally, If i try to flash any sparsechunk it will also give the error " invalid signed image".
I'll have to say that trying to enable USB debugging vía fastboot is an excellent idea, i did't try that, i hope i can do it without the recovery cuz i can't boot to it and until now, i couln't flash any recovery.
Thanks again!
Edit: I've read quite a bit and seems like in every case you would need a working recovery to allow USB debugging, so I think I can not do it in the actual state of things haha.
Edit2: I have a pair of questions:
1. Do i need to check allow oem unlocking in developer options in android 6.0 in order to unlock the bootloader?
2. In order to use RSD lite and it recognizing muy phone do i have to have USB debugging allowed?

I don't know - I did.
Probably. I didn't know you could use RSDlite on the Moto g3 - paste a link if you find one!
What do you say you did? Didnt understand that

Sorry - I believed I switched on that switch for allow bootloader unlocking as well as USB Debugging.

Hey friend, i don't want to be a pushover. You're taking the time to help me and i see that, but i saw the video, and he starts the phone by making a data erase, i already did that, and the phone refuses to start. Same error. "version downgraded for boot" "failed to validate boot image" "fastboot reason: fall-through from normal boot mode".
And says in big red letters "Start up failed: Your device didn't start up succesfully. Use the software repair assistant on computer to repair your device."
I feel like i've tried everything.
Thanks again.
My phone is totally ****ed - Device does not have DRK, please install DRK first...
I try to flash stock firmware but this just comes up when it boots. If I leave it a whilst it will just load into the stock recovery and it says 'device does not have drk, contact to SW PL, please flash ENG binary and install DRK'.
Can't find any guides or anything in the internet hmm.

Did you ever figure out the fix for the DRK error. I have the S8+ and just got the same thing, and I can't find a fix for it. Sounds like from another thread, that it's going to be pretty tough to overcome.
DRK means BL file

If you get DRK problem in your samsung mobiles, it means install correct BL file (Ap, Bl, Cp, CSC )
first check your BL file using odin
how to chek:
1 open odin
2 click on BL
3 select correct odin file
4 put your samsung mobile into downloading mode ( volume down + home button + on/off )
5 connect your mobile via original usb cable to your pc or lapptop
6 click start button in odin
if you got error or fail it's not your correct BL file and you i'll get DRK problem
BL file problems :
DRK error
DRK not find
No support single_SKU
supported API: 3
Dm-verity error....
failed code : 0*02
E:failed to find /misc partition

Me funciono rooteando el equipo en el s6ede g925t, pero en el g925i no funciono rooteando...
Hi guys:
Once again it's me... I have tried with no success to "covert" my Axon 10 Pro from Mexico (Guess US model, 855A03 no NA 855A03_NA) to EU, I have downloaded several zip files from XDA and other sites. I have tried with QFIL, MiFlash and the EDL tool as well.
But none of them work, do you know if this is possible or a guide to do it?
MiFlash: Download Fail:System.Exception: Unable to download Flash Programmer using Sahara Protocol
QFIL: Error (can't remember right now)
EDL: Error (can't remember right now)
Or maybe a way to recover fastboot to try the Lineage ROM, since I don't have it... I tried with adb reboot bootloader (no go, the phone restarts and goes directly to the carrier logo, no fastboot) I have tried with the vol - and power keys (no go, the same).
Ooooooorrr.... Maybe a way to install TWRP from EDL since I haven't fastboot, I've tried with emmcdl:
emmcdl -p COM4 -f prog_ufs_firehose_sdm855.elf -b recovery twrp.img
It appears to flash it, but after that it reboots and the old recovery is there.
Kind regards!
So... I've finally installed TWRP using a ROM from other forum, but in the end it didn't end as expected, I could install recovery, then I tried to install lineage but... Bootloop.
I´ll try again later.
JUst to let you know, is possible to install TWRP. I'll post my tutorial later. Regards

I have the same version (telcel) es una lástima que Telcel ni ZTE le den seguimiento para actualizar, si pudiste cambiarlo a la versión de EU o internacional, agradecer
