My bootloader unlocked RETEU 1900-7 is running 8.0 November 2018 update on slot B and received the OTA today. But no matter what I tried, it failed to install.
This is strange. I have received one OTA (8.0 security patch) once and could install it.
I tried
removing Magisk
fastboot oem lock
but still no luck.
So I have picked the OTA payload.bin and have converted it to several fastboot flashable images.
But I get more images than I have previously seen, e.g. cmnlib64.img. And flashing those images fail all the same way:
Code:
C:\Users\Olaf\Downloads\ROM9\flashable>mfastboot flash xbl_a xbl.img
target max-sparse-size: 256MB
sending 'xbl_a' (2247 KB)...
OKAY [ 0.062s]
writing 'xbl_a'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.078s
The usual stuff like system.img installs just fine, even with a 3 GB system.img. But when I say "fastboot set_active a" and reboot, booting fails. "fastboot set_active b", and I am back at 8.0.
What can I try next?

1) Keep bootloader unlocked.
2) Flash stock 9 retail firmware. Download it here. Make sure the flash script leaves 'userdata' alone.
It has worked well. Thanks!

I have tried everything I have read on here and I cant seem to flash recovery. I used pwnmymoto to gain root when I first received my moto x. When the camera update came I thought I unrooted and flashed back to stock becasue I was able to get the OTA. Yesterday I could not install the OTA 4.4 because it gave me a error sign. I tried to flash recovery using fastboot but everytime now matter what I do this shows up:
colins-air:Android Tools colinj22$ ./fastboot flash recovery recovery.img

Can someone please help me. I am fairly new to fastboot and I am on a Mac and I have read everything in these threads and nothing seems to help. Can I erase everything and somehow start from scratch?
Thank you all!

try using a different fastboot besides the one you are using. also make sure you are trying to flash the right FW version. you can't downgrade FW so it needs to be the FW version that is currently on the device.
try the second link in the OP of this thread for a different fastboot
http://forum.xda-developers.com/showthread.php?t=2489249
Flashing recovery requires a unlocked boot loader, you're obviously on Verizon and unless you have a DE moto you can't flash recovery due to your boot loader being locked

EDIT 3: Okay, just flashed a new kernel and the WiFi is working now. Must have been the stock kernel for some reason.
So all problems solved now
EDIT 2: Succesfully flashed the ROM, but unable to connect to Wifi. When I press the on button, it switches on for a second and then switches off again. Any idea guys why?
I've been trying to flash the stock ROM, but can't because as soon as I begin with the first step i.e fastboot flash partition gpt.bin, the following error is displayed- fastboot preflash validation failed.
Now I've been reading up on the forums here and a some have said that this error occurs when someone tries to downgrade. But I'm on the latest build and I don't know why this is happening?
Just so everyone knows, I'm unlocked and rooted.
Please, I need help since the ROM I'm on, which by itself is stock, is pretty much not working.

You can ignore gpt.bin and motoboot.bin. They won't flash if the same or lower version. Not a problem. Just continue flashing the other files.

Okay, thanks man, I successfully flashed the ROM. But now I have another problem. I'm not able to switch on my Wifi. When press the on button, it switches on for a micro sec and then switches off. Any idea why?
Don't know. Maybe a reboot. After that I would wipe dalvic, cache and data?

I did better, a factory reset. Nada.
Would flashing a different kernel help?
Did you do a
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
This is a wififix for the kernel

Oh I didn't know that this was a wifi fix, but yes I did perform the above steps as well.
But anyhow, I flashed a new kernel and it did solve the problem.

Didn't you read anything of the previous posts?
If you've unlocked your bootloader, and getting these errors, you can safely ignore them. Just carry on flashing the other files.
Carried on
I did carried on with the fastboot steps but I get this "UTAG "flashfail" is configured as fastboot" and I'm still stuck in Bootloader.
How do I change the Kernel?
Oh yeah, I updated to Lollipop about 20 days ago, worked fine until a few days back and suddenly I get these strange errors. What could be the cause though?
Hello guys, so yesterday I got into a bootloop on my Moto G 2014... Then I tried to flash the stock ROM to solve the problem, but every time I execute the command line:
mfastboot.exe flash partition got.bin

If you already updated the ROM, there are two images that can't be downgraded. The first is gpt.bin and the second is motoboot.img
Just ignore these two and continue flashing.
Thanks

Good evening guys...
I have a Moto X 2nd gen (XT1097) with Stock Retail BR Rom and it was working like a charm till this morning.
I received a notification of an OTA Update (security patch) and I wanted to patch the phone...
I know a rooted phone (like mine) could not receive OTA Updates, so I flashed stock rom again with RDSLite like I always do.
The problem occured when I try to root it... I picked a wrong file to flash with the TWRP and cel got stucked in the boot logo.
When I try to flash the Firmware stock 6.0 in the RDSLite, It returns a error like that:
Code:
fastboot flash partition gpt.bin
target reported max download size of 536870912 bytes
sending 'partition' (32 KB)...

I asked a friend of mine that have the same device and the version of his bootloader is 60.18 (sha-3b3b501 ... )
my bootloader, after I fuc*ed the device is 60.00 (sha-130760b ... )...
I can still turn on device, can flash the firmware if I erase gpt and motoboot lines from flashfile.xml but I cannot OTA and root, got some errors!
Anyone knows something about that? Can I try to downgrade to solve? Anyone knows this bootloader version???
Sorry about english...
I tried every ROM (4.4.4, 5.0, 5.1 and 6.0) and all of them returns the message "version downgraded for primary_gpt"... FU*K this SH*T!!!!
My bootloader is at 60.00 version and I really need to put the 60.18 version... How to do that?
Every time I try to lock my bootloader again on my Moto G6 XT1925-3 through the rom stock I get this error:

You're trying to flash an older firmware than the one you're on now. It's going to fail and if it succeeds it will brick your device. you'll need to find a firmware package the same or newer than the one you're on now.
Relocking the bootloader may not be possible many have tried and failed

Flashing stock will not re lock bootloader. But you can find some stock firmwares here
You'll have to see which one you need. I don't know what region your phone is or what firmware is on it.

It's almost inpossible to relock your bootloader because you need to have signed that not bad boot.img and ect. As long that you don't have those files you will be unable to relock the bootloader. I have noticed the same thing when i was trying to relock mine bootloader on my moto g6.
