I've got a Moto G4 Play and with LineageOS I can't make any calls. So I wanted to downgrade the firmware to the stock-firmware which I downloaded here: bit.ly/2lvXpgC. There are instructions how to downgrade the firmware here: bit.ly/2kPAuNS.
The first command - "fastboot oem fb_mode_set" - is accepted.
But the second command - "fastboot flash partition gpt.bin" - produces the following:
"target reported max download size of 268435456 bytes
sending 'partition' (32 KB)...
OKAY [ 0.008s]
writing 'partition'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.442s"
Can anyone tell me what I'm doing wrong here?
[EDIT]:
I simply run the other commands and ignored those that failed. Now my Phone boots into the bootloader and if I press start, I get into an endless boot-loop. If I start the TWRP recovery-image with "fastboot boot twrpxyz.img", the device restarts and stops in the bootloader, i.e. the recovery-mode isn't started.
Can anyone help me from here?
[EDIT2]:
I've got the problem: I tried to boot the bootloader without a battery in the phone and just the USB-cable attached. So I suspected this was also the problem when flashing the stock-image and I run through tge commands to install it. I simply ignored that "fastboot flash partition gpt.bin" didn't work (according to someone who had the same problem here in this boadd) and every other command was successful. The phone booted the stock firmware and everything is fine now.
Thanks you so much
Work fine for me, only i found the solution here, seriously, thanks!!
GOD BLESS YOU

Hi guys!
I hope you can help me, since I've looked everywhere but can only find people with similar but not the exact same problem.
I tried flashing TWRP in order to migrate to a custom ROM. I am currently running official 7.1.1.
When I try to flash twrp (tried several versions) the command window shows me this:
c:\adb>fastboot flash recovery twrp.img
target max-sparse-size: 256MB
sending 'recovery' (14522 KB)...
OKAY [ 0.049s]
writing 'recovery'...
(bootloader) Image recovery failed validation
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.068s
I tried using Moto fastboot as well but with the same result. I'd really appreciate your help. Please note, that I am not a pro like most you guys so I might have follow-up questions
Are you sure you flashed the right image? And that your bootloader is unlocked?
And what happens if you use
Code:
fastboot boot twrp.img
?

Yes, I am sure that I am using the right image. I tried several, always checked that they were for addison.
I also unlocked the bootloader in developer options - although now that you mention it: in the fastboot screen it still says oem_locked. So maybe that is the problem?
c:\adb>fastboot boot twrp.img
downloading 'boot.img'...
OKAY [ 0.047s]
booting...
(bootloader) permission denied!

Okay, I managed to unlock the bootloader with the unlock key I got from Motorola.
Now when I try to flash it says:
c:\adb>fastboot flash recovery twrp.img
target max-sparse-size: 256MB
sending 'recovery' (14522 KB)...
OKAY [ 0.049s]

Oh Jesus... Bootloader unlock is not just the option in Dev settings. Google it, you'll find a website from Motorola that guides you through the process and provides you with everything necessary
Yes, I did that by now as I said in the post before. Sorry, but I'm a beginner
Now it says that the image is not signed or corrupt. IDK what to do anymore.
Booting in TWRP works but when flashing Lineage from SD card I get the error:
recv error on unevent
and
failed to mount data.
I wiped everything using TWRP and I also tried to use another version of TWRP, so a corrupted file can't be the problem.
I figured it out.
I had to restore the file system by only checking the "System" box when wiping with TPWR - just in case anybody else has the same problems.
So a factory data reset solve the problem? Having your first issue with moto e5 cricket and you can't unlock three bootloader

well, i had it unlocked via the settingsbutton and after read this here , via the website where you can get the 20 bits code, but it is the same result with a code that is the same as the adb devices code, just as before! Only thing that is changed is a warning when you starts the phone up.

Can you tell me how you got the phone twrped, pls?
SOLVED I will make a topic about it https://forum.xda-developers.com/g5/help/how-to-revert-moto-g5-xt1670-to-stock-t4183425
Hello, how are you all over there? I here in trouble with this XT1670. I have installed several roms but now i want to go back to the official one, but it dont lock the bootloader.
Tried the following command (twice) to lock the bootloader: fastboot oem lock
And i get the following result:
Code:
(bootloader) Flash valid Android images now
(bootloader) Then re-run this command to lock
OKAY [ 0.016s]
finished. total time: 0.016s
Now i use the following command: fastboot flash boot boot.img
And the following was obtained:
Code:
target reported max download size of 535822336 bytes
sending 'boot' (16384 KB) ...
OKAY [0.545s]
writing 'boot' ...
(bootloader) Security version downgrade
(bootloader) Image boot failed validation
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.747s
I have already tried several. Boot, gpt, oem with official rom. All showing the error "Security version downgrade"
I also tried Lenovo's Rescue & Smart app, but it says the SKU is wrong and doesn't recognize the mobile phone.
I don't know how to continue. I could put an official rom, but when you restart the phone the bootloader appears. It only starts when press start.
Not only does that happen. Every so often, the phone turns itself off and remains in the bootloader. And then when you start up, bug reports pop up to share with who knows what.
I do not know what to do. You are the experts.
Ty in advance
So, here I was thinking things couldn't hurt to do some customisation.
This evening, I flashed a custom logo... using fastboot. (fastboot flash logo logo.bin)
That was the last thing I saw on my device, it won't show anything anymore.
Any advice on how to get any connection to my device again?
Right... So as before I found the solution myself.
I used the BROM to reflash the logo with the proper image.
For whoever wants to know. I used the MTK bypass utility to bypass the authentication stuff, and the SP Flash tool to flash.
I did have to use libusb-win32 for the python part, took me some hours to figure that one out. All sources told me UsbDK would work for that.
Kind of relieved I actually managed to unbrick my phone.
Did you get solution?
As mentioned in the post right before you; yes.
Hello,
I'm a beginner in the field of flasing custom roms but I would really like to abandon using google on my phone and find your work here really awesome. So yeah, I hope my question doesn't sound stupid but I'm seriously stuck and hope I didn't completely break my phone.
I am using a Redmi Note 8 (2021) and wanted to flash lineageOS. So I unlocked the bootloader via my mi account, booted into fastboot mode (usb-debugging was of course enabled) and tried to flash twrp to recovery using the cmd-window via platform-tools.
This didn't work because when I typed:
./fastboot flash recovery twrp.img
I got the reply:
Sending 'recovery' (65536 KB) OKAY [ 1.743s]
Writing 'recovery' FAILED (remote: 'This partition doesn't exist')
fastboot: error: Command failed
I therefore started googling and found a threat on xda where someone had solved the problem by replacing 'recovery' with 'boot':
./fastboot flash boot twrp.img
What I got was:
Sending 'boot_a' (65536 KB) OKAY [ 1.818s]
Writing 'boot_a' OKAY [ 0.827s]
Finished. Total time: 2.681s
After that my phone was bricked. I cannot enter recovery mode anymore and even fastboot mode appears a bit different (I don't see the bunny anymore, all I see is the word 'fastboot' in orange letters on a black screen). When I enter fastboot mode, the device is detected by my computer - the only sign that still gives me an inch of hope. When I'm not in fastboot mode my phone keeps vibrating and then turning of, then suddenly it vibrates again and turns on, the logo 'redmi' appears and then it suddenly turns off again - and it just keeps repeating this procedure.
I downloaded the mi flash tool and tried to flash the Xiaomi ROM, but that didn't work either - after about five minutes of waiting I get an error. I tried different versions of MIUI but keep getting errors. When I try to flash the Xiaomi ROM via cmd-window, as suggested here ( https://www.droidwin.com/unbrick-redmi-note-8-fastboot-commands/ ) I get this:
fastboot flash xbl_a xbl.elf
Sending 'xbl_a' (3449 KB) OKAY [ 0.105s]
Writing 'xbl_a' FAILED (remote: 'This partition doesn't exist')
fastboot: error: Command failed
Is there anything left for me to do or should I give up and save money for a new phone?
I would be very, very grateful for help
You could try this: fastboot --set-active=b

Try this

I guess you have used a wrong recovery file, maybe one for another device
The problem is that the command 'flash recovery' does not work, because it says th partition does not exist....

wrong forum ! , see Biloba forum
on some devices, boot+recovery are on the same partition, but not for Biloba
boot partition (+dtbo on some cases) is the kernel
i think you should look for official install of miui rom since it has IMG of most partitions ...

Use this tool:
https://forum.xda-developers.com/t/flash-tool-guide-use-xiaomi-flash-tool.4262425/
First off: don't go punching in commands you don't understand.
You literally flashed an incompatible image to your boot_a.
You could try and set the active partition to b using: fastboot --set-active=b.
Other option, if you have the firmware image for your boot partition, flash that image to boot_a.
you only need to flash the original boot.img from firmware lol it's so easy
