Well, I tried to install the stock rom, but even in the first attempt that popped up. I had Lineage OS before the installation

The error comes up when the bootloader is locked. Is your bootloader unlocked?
If it's unlocked follow the guide by fireball0093 on getting to stock firmware and recovery,.

hello
I have the same problem but with the bootloader unlocked and when I try it, it comes out failed remote failure
i have done a month research and found this https://www.youtube.com/watch?v=IRa97F14RKE&app=desktop
it's not in english thou u could make use of the links in the description not the video. even i had the same preflash validation failed error with an bootloader version 81.12 with bootloader status 0 on my xt1602. just flash it like u flash a stock rom. the reason for our error is we still didn't have the proper stock nougat 7.1 rom for our device. roms available in the internet are not working but this one works. be sure not to downgrade your'e phone and take an ota coz. the bootloader can't be downgraded and when it installs an older ota boom phone is bricked. make sure u flash some blank flash files of harpia before doing this. first u need to soft brick ur device from hard brick that have occured
my issue with xt1602 appears to be incorrect (I can't really properly comment on this) blankflash - I get stuck with 0x69 CID and phone suggests using verizon tools (while the phone is just RETIN originally). At this rate I can't re-hardbrick the phone into Qualcomm loader (qloader for "qboot" tool to work) so I can't even flash stock rom provided in Your, @keerthi perumal, link. So I am currently at a real loss here with non functioning device. My only hope is that someone actually helps to re-hardbrick device - No combination of fastboot commands (and different versions of adb&fastboot) to boot into "edl" (fastboot reboot edl) worked for the thus far.

Hey guys.... I have a Motorola xt1563 dual sim. A week ago I was trying to flash my phone with this rom:
XT1563_LUX_RETCA_5.1.1_LPD23.118-10_cid14_subsidy-DEFAULT_CFC.xml
But unfortunelly doesn't boot. The display only show me a text:
AP Fastboot Flash Mode (Secure)
failed to validate system image
ERROR: Failed to pass validation, backup to fastboot
Fastboot Reason: Fall-through from charger boot mode
My phone is not unlocked and no root.
I really don't know what to do, anybody can help me? Any idea?
Thanx a lot....

Aldo.
I do it, I try to unlock this device but nothing happends.
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
finished. total time: 0.053s
Do you have any other idea? Thanks, man.
I assume you have a mexican or brazilian XT1563 the firmware you used is not made for it. I looked around and found a file factory page
http://www.filefactory.com/folder/dd05c058d3ff8dbe/?sort=created&order=DESC&show=100&page=1
My BLIND guess is
XT1563_LUX_RETLA-IUSMX_5.1.1_LPD23.118-6.2_cid12_subsidy-IUSMXLA_CFC.xml.zip
this based on the IUSMX (which I assume means U.S and MEX)
Again it is a blind guess so double check, then triple check and proceed with caution.
not sure if I can actually link out to another page if not mod let me know and I'd be happy to take it down. Otherwise I have previously stumbled upon some forums in Spanish and Portuguese which point to the right firmware. I'd suggest look into those as well.
As usual google is your friend.
Hope it helps.
hey Joeanca....
I read your comment and that's true I have a Mexican XT1563, I will download all the firmwares and I try it, thats interesting.
About your blind questions.
IUSMXLA means
IUSACELL (name of the cellphone Company)
MX means Mexico
LA means Latinamerica
I will do it with caution, but let me explain you. I even downloaded the original firmware from motorola's webpage and also follow the instructions but nothing happends, the phone still show me the bootloader options with this message.
AP Fastboot Flash Mode (secure)
failed to validate system image
ERROR: Failed to pass validation, backup to fastboot
Fastboot Reason: Fall-through from normal boot mode
I'm not sure what's happening. And you say it, google it's a great tool, but I have a week searching for a solution but I can't find it.
Thanks for the advice Joeanca. Have a nice day. And if you know any other idea please let me know.
Go to About Phone in Settings.
Then click build number 6-9 times until it shows 'you are now a developer'.
Then go to Settings > Developer Options and select OEM unlock.
Then unlock you bootloader.
Flash a custom recovery (TWRP).
After that root your device.
And finally flash a custom rom.
Hey Sid.X
When I turn on the phone only shows the display in recovery mode, unfortunelly I can't do it all con can say. And the phone can't load Android, so that´s the problem. I can't find the solution because my phone is not working. I try to install the original rom from motorola's web page and nothing happends.
The phone also is oem locked and never root, and I buy it 2 months ago.
Do you have any other idea? Thanks for the advice, I hope somebody can help me.
All comments will be wellcome.
Thanks anyway, have a good day.

how were you flashing RSD LITE or manually??? dis you flash bootloader. bin and gpt.bin ??
if you have the bootloader blocked even have guarantee of purchase go claim it...
about warranty thing...they are saying motherboard is locked...they have to change it...which cost too much...also try using RSDLite...I am having same problem but RSD Lite could not recognise my device...Try fix it through varizon wireless repair assistant...If that doesn't work too let me know which version of firmware you were using before you did this to your phone.

Yes, downgrading is possible with unlocked bootloader (locked bootloader doesn't allow downgrading). The first 2 commands ("fastboot flash partition gpt.bin" and "fastboot flash bootloader bootloader.img") always fail when downgrading, and can be skipped without any issues, so if the error you got was for one of the first 2 commands just continue with the rest of the commands.

Thanks, I was start to supposing that the locked bootloader was the problem and you just confirmed. Unluckily right now I can't unlock the bootloader so I think I must wait for the release of the complete EU 6.0 Firmware.

In your post you mentioned "unlocked" so i assumed you had unlocked the bootloader already. I'm afraid that downgrading is only possible if you unlock the bootloader, or you can wait for EU 6.0 full stock ROM to become available and try installing that (it might work as you'll be going from 6.0 ROM to 6.0 ROM).

Have you tried what panart said, about skipping the first 2 fastboot commands ?
I also downgraded to 5.1 skipping the first 2 lines and it was working fine.Only I had an unlocked bootloader at that moment ,but maybe it wil also works with a locked bootloader, not sure.

Yes, I've tried both. With and without the first two commands (fastboot flash partition gpt.bin / fastboot flash bootloader bootloader.img), but it fails in every case. Purposely I get the errors when I launch this commands:
Code:
- fastboot flash boot boot.img
- fastboot flash system system.img_sparsechunk.*
All the other instructions work fine.

Hello I have bought an Asus ZC520TL it is the X008DC variant with MT6737M, I have bricked the phone and the only frimware at my disposal was WW variant I need someone to do a readback with spflash and supply the stock boot.img and recovery.img I have access to a develpment rom that has come from stock roms it has full root access but fastboot is dead as the WW firmware re-locked the bootloader and my IMEI is gone I am also unable to get into meta mode because I am not on PCT firmware. The phone is mt6737m varient US_Phone. I can flash the readback recovery and boot with DD and then upgrade to nougat US_Phone variant. Any help is much appreciated many thanks in advanced I can supply scatter for readback if needed.
Actually I think any US_Phone recovery and boot will do or if anyone has any idea how I can flash boot.img from asus stock with the boot.sig by bypassing with adb that would be great too I have full root access in adb in recovery mode I flashed twrp with DD today and it will not work because it is not having the signature.
SOLVED IT only took me 3 days It was much easier then I thought
I will make a guide for full unbrick X008DC from WW to US
Could you give me the link to download the recovery.img for X008DC? I also bricked mine
Yes I wall make a backup for you
I just need to revert back to stock and I wall make a backup
Also are you completely bricked? or can you still fastboot? Also was your boot-loader unlocked

It all started with an error while in B330 oreo, try to install the latest version b343, and by mistake place the firmware of b151 naugat in the folder of HWOTA, without realizing I slipped in twrp and stayed in the logo, it was impossible to revive it by fastboot , the partitions had been totally erased, a technician revived it with a dongle box, installing everything from scratch. I am in b151 naugat and the boot manager unlocked but I got the OTA b343 Oreo and proceeded to install it, I tried to unlock the bootloader but it is impossible for me FRP UNLOCK, PHONE RELOCKED, try fastboot and ERROR FAILED, I wanted to get back the unlock code in DC_UNLOCKER and it is not possible so I am in B343 OREO, today return to NAUGAT by HISHUITE already being in b151 proceeded to unblock it with the code that did it before and the same error was failed and follows the RELOCKED boot manager, but not LOCK, even though it is a new firmware.

Mate 10 lite came with nougat
The at&t version from México originally come with Android 7.1 NOUGAT in the versión C121B100
Si many latinoamerica versions has the same version.
Fot the relock problem you must do the same ateos for unlock, but you have to wait 7 o 14 says, i don't remember, but after that you should be able to reunlock your Huawei with the same code because it's the same serial number.

I still think you're in the wrong place, haven't seen anything here even remotely connected to the lite version of the mate 10, I'd search and see if there is a forum for that phone. You should be able to unlock the phone again, unless of course there motherboard was changed (that hooking up to a dongle story by the technician is kind of suspicious as the hardware to do that repair is not a dongle and is very expensive)
I managed to unlock using dc-unlocker but I generated the same unlock number I already had, the strangest thing was that I paste and copy and unlock. I am confused because the codes are the same and with the first one it does not let unblock and with the second code if, in order and I already achieved what I wanted to thank you all.
I had several ROMs on my pP9 lite and after some time I decidet to unroot and go stock again. I don't remember how, but a locked the bootloader and installed stock rom.. everything OK, but after an OTA update I got no bluetooth and I can't install now any other rom cuz I lost my OEM unlock code and now I can't get it from Huawei... When I go to fastboot, I have PHONE Unlocked and FRP Unlocked too, but I can't flash the recovery... it's like the bootloader is unlocked, but it don't let me flash my EliteTWRP image... I get FAILED (remote: Command not allowed)
Any sugestions on how to fix this? I want to give this phone to my nephew, it is still a good phone for some games and whatsapp

Hello,
even if it says it's unlocked, it's actually locked.
So you need to unlock it again if you want to flash stuffs...
Good luck
P.S.: About your other post... You cannot flash with dload method on android 7,
you need to use Elite recovery and HWOTA method or Huawei Recovery Updater to flash the firmware
you want. ( be sure you choose the correct firmware )
Cheers
