There is NO unlock if not unlocked prior to 98.16.3.

You can't downgrade versions. However, that system version is rootable, though. With that being said, go through those threads that Avi posted or download your firmware from this website and flash in RSD. Your battery needs to be charged prior to doing this, though, so if it's not, put it on the charger now.

Hello everybody, I am a newbie in these things and I need some help.
Also, sorry for my bad English
I've got xt907 and I wanted to install CM in it. I've tried to root it following this http://www.droidviews.com/root-verizon-droid-razr-m-on-kitkat-firmware/ instruction but failed because of "(bootloader) Preflash validation failed FAILED (remote failure)" error. After that I downloaded http://forum.xda-developers.com/showthread.php?t=2207419 utility, tried to use 1 and 2 options, got some errors and after that when I'm trying to boot Android i get stuck with frozen touch screen (like here: http://www.droidforums.net/threads/touch-screen-and-touch-sensitive-buttons-not-responding.240136/ ).
Any ideas why I failed to root my razr and how to fix that touch screen? Thanks in advance!
Try to use rsd and flash the stock 4.4.2 firmware... Then go ahead and root it and unlock the boot loader if touch returns... If touch doesn't after rsd you may have a hardware issue... All links are posted here courtesy of ATTACK... I believe your root failed because you were on 4.4.2 and didn't read the whole article... I may be wrong but it sounds like you attempted the first method of rooting posted in that article... Rather then where it says update

Hi everyone,
I would like to know if is possible to dowgrande to a different country firmware (I'm not interested in the dual sim option). Anyone know if this is possible? I have a locked and non rooted moto x play. I've tried to follow this thread REMINDER HOW TO DOWNGRADE from 6.0 to 5.1.1, but the installation fail with this error:
(bootloader) Invalid signed image
(bootloader) Preflash validation failed

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).

Ooops, sorry. It was a typo, I've just fixed it. Yes, right now I'm waiting for the release of EU 6.0 full stock rom and then I'm going to retry to flash it!

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.

You can flash it directly On any XT1562
Currently I have installed latest official nightly LineageOS 14.1 on my device. I want to return to stock ROM and lock bootloader. Previously, before bootloader unlocking, I had 6.0.1 stock, version with january security updates (probably).
I have downloaded latest stock 6.0.1 MPD24.107-52 ( https://github.com/motoxplay/stock ).
Unfortunately, I got an error when tried to flash it:
HTML:
$ fastboot flash partition gpt.bin
it returns:
HTML:
(bootloader) Preflash validation failed
same with recovery.img
To lock bootloader I have to flash all stock files.
Any ideas? Thanks
skip it. You cant flash same bootloader and same gpt.bin again.
https://forum.xda-developers.com/mo...de-return-to-stock-relock-bootloader-t3489110
NOTE: You must use a factory firmware image that is the same version as what you have installed or newer to successfully relock the bootloader, you cannot just grab the old (shipped) version from Moto's site. If you attempt to use a firmware image that is older than what you have installed currently, you will receive a Preflash Validation Error indicating such when you attempt to flash the partition table (gpt.bin). At this point you can either continue the flash and NOT lock the bootloader at the end, or stop until you can find the most current image. Moto used to be quite willing to hand these out when they were requested, so if you have a very new firmware installed you may not find one that you can use to relock with on the Internet. Part of the requirements to lock the bootloader is you must successfully flash the partition table (gpt.bin) in order to complete the lock process, if you can't then the bootloader lock process cannot be finished.

so i have to wait for the official nougat flashable file.

any workaround?
Good morning everyone, i have a horrible problem with my Moto G5 Plus XT1685.
I had the stock version NPNS25.137-33-11 of the firmware a couple of days ago, and i decided to unlock my bootloader and flash one custom rom.
Well, i did it but i realize i can't use Android Pay and i need it.
I tried to flash a firmware via ADB but i'm getting this error when i write "fastboot fash XXX XXX.img"
Code:
(bootloader) Security version downgrade
(bootloader) Image o failed validation
(bootloader) Invalid signed image
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 1.689s
I would RELOCK my bootloader and FLASH the original firmware but i can't because of this problem. Who can help me?
Thanks in advance
Unfortunately, to lock your device, you'd likely need the NPNS25.137-33-11 stock firmware to flash; generally, only stock firmwares of the same build or newer than what you have will be able to re-lock your device. Currently, I can't see that particular firmware having been released/leaked.
If you need Android Pay, you may wish to look into rooting and using magisk to hide your unlocked bootloader status, which may give you SafetyNet and Android Pay. I'm not familiar with rooting and with magisk on G5 Plus devices though.

You can flash any potter fastboot you want, upgrade/downgrade, whatever; just don't flash the bootloader or gpt.
As long as you skip these, you won't have any issues.
FYI, flashing a stock fastboot file will NOT relock your bootloader.

Agreed, magisk is the way to go for root and solutions for rooted devices on the g5.
Thanks both for the replies, very helpful.
But how about relocking the bootloader? There is nothing I can do? I know you reply me yet about this, but I just wanna be sure..thanks again

Until the NPNS25.137-33-11 or newer stock firmware comes out, I think you cannot re-lock your bootloader (and as I mentioned, I see no sign of such stock firmware). Only stock ROM firmware of the same build or newer than the bootloader patch level on your device can re-lock your device.
Many thanks sir, very helpful.
I think we solved the problem.
hi now I no you prob see this title and think oh another 1 but hear me out as I cant find any thing the same as the issue I'm having.
so I followed a rooting guide unlocked bootloader installed twrp all good installed supersu phone wont boot reinstalled twrp systemless installed supersu still nothing I have followed every guide I can find phone will only boot into twrp or bootloader I have flashed custom and stock roms however I do keep getting

I have tried every way I can find still nothing when I try to boot it freezes on the screen saying my phone is unlocked and cant be trusted I'm now lost don't no were to go from here I did not back any thing up as the first thread I read don't say bout it and iv neva had any problems with any of my other phones or games consoles I no games consoles are different any help would be amazing
Most likely the flashing wasn’t complete or corrupted or the stock ROM wasn’t the correct one (Remember to be safe you’d have to flash the original ROM when you bought the phone) that being said. My suggestion you should try flashing TWRP again and boot into TWRP. Then flash stock ROM which will overwrite the current config. Not guaranteed, but it’s worth a shot.
Good luck.

Sorry to sound dumb flash it through twrps? I can get twrps to boot but thats it iv flashed through bootloader putting all commands in separate but when i tried to boot it came up with no command with the andriod dude with a red triangle above him but i can flash and boot twrps after this
1) If you're rooting on stock Motorola Nougat ROMs, you need a custom kernel - attempting to root on the stock Motorola hudsoncm kernel usually results in a boot failure or bootloop as you've found. https://forum.xda-developers.com/mo...de-root-moto-g4-plus-supersu-android-t3587918 for a useful guide, you can root with either magisk or SuperSU.
2)That security downgrade error suggests you're attempting to flash stock firmware older than the firmware matching your device's bootloader. If you need newer firmware, you could look into this thread: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 You'll need to flash this firmware via fastboot/the bootloader.
3) Try first of all booting into TWRP, copy a custom kernel to your device via a computer and USB cable, and then flash the custom kernel. See if that gets your device booting. If not, you may have to re-flash the stock firmware to get your device booting again (or use a backup, if you had one).

Unfortunately you'd have to wait for a newer firmware, the NPJS25.93-14-13, NPJS25.93-14-15 and NPJS25.93-14-18 firmwares are for retail devices. Amazon devices are on a different firmware and as you've partially flashed the Dec 2017 firmware, you'd likely need AMZ NPJ25.93-14.7-3 or NPJ25.93-14.7-5 (Feb 2018 update), however neither AMZ build appears to be available at the moment.
If you're desperate for a working device, your best bet may be to talk to Amazon or Motorola support, or if your bootloader was previously unlocked, you could try to unlock your bootloader and flash a custom ROM.
I will wait for a new firmware amz
