First of all. i want to instal CM13. I rooted my device it all went smooth. I even tick "enable oem unlock" in the developer settings.
Now things get out of my hand.
I booted up stock recovery. Format dalvik/cache and (its the mistake) i formated userdata. now i try to flash TWRP with fastboot. It say it cant flashed becose of OEM is locked. Alright . I try to boot the stock rom but it wont boot. It goes back straight to the stock recovery without touching any volume button.
Now i read through almost all forums , even other phone brands. The thing i need is the oem key. but The offical huawei page where i can get one is say that i need the model name, serial number , imei number and product ID. I can enter 3 out of 4 becuse its on the back of the phone. But to get product ID i need to boot into the ROM than enter a special key combination to the dial and i get the code. Question . IS there anyway to get product id or unlock oem without ROM?
Things i try but didnt work :
-Unlock oem through bootloader (fastboot ouem unlock and unlock go)
-fastboot boot recovery.img (it say that the device locked)
I really hope that someone could help me with this problem. Thank you folks.
PS.: sorry for my poor english i try my best.
No way to unlock y560 bootloader. I asked Huawei support also but they said that for this model they don't provide unlock code!

First, let me say this because i've used xda for a while and i know im going to get these responses:
I know this wont reinstate my warranty...
Why? Because I want to. I understand you think it's useless but it's not your phone...
I have tried "fastboot oem lock" and it doesnt work...
I've searched Motorola's site, got on a chat with them which was useless, and searched xda...
So I booted into AP fastboot and connected to my computer. Opened CMD and typed "fastboot oem lock begin"
That seemed to start the process so then ran RSD lite (as admin) and flashed a signed xml of 4.1.2
Yes, I edited the XML first and removed the 2 lines with "getvar" in them
RSD finished and the phone rebooted (which was great because before it was hung up on the unlocked bootloader warning)
Unfortunately after turning the phone off and then back on, the unlocked bootloader warning screen still came up.
And after booting back into AP fastboot it still said UNLOCKED.
did i miss a step?
I need to relock the phone. if anyone has useful information it would be extremely helpful. in the event it just cant be done thats fine. but i feel like it can, because after fastboot oem lock begin the command prompted told me that now i can flashed the signed images.
well crap. i may have just answered my own question. do i have to flash manually through CMD (ie fastboot flash system system.img) AND THEN run fastboot oem lock at the bottom? i'll try it tomorrow.
before i started this the phone was stuck on the bootloader warning screen so if anyone is stuck at that point this will allow you to boot up your phone. and if my results are typical, it did not relock the bootloader (obviously). hope I helped someone. hope someone can help me. thanks.
most likely not feasible
unlocking razr m involves phisically blowing a q-fuse, so you can't go back to locked
even if you could, it would be traced forever that you've unlocked the BL
You can relock the boot loader on the Dev edition, but once unlocked you can never go back to original status 0 of the boot loader and the boot logo will always display the warning even if you relock the boot loader. You have to flash that partition with another logo image to avoid that.
You also need to wipe the user data partition in fastboot first for the fastboot oem lock begin command to complete successfully.
Once that is done, when it reboots you will see that in fastboot it will display status 2 locked instead of status 3 unlocked.
This is a physical change that happens to the hardware when you unlock the boot loader an efuse on the board is blown and that memory location is permanently programmed. Its not even a question of them knowing, even though they do of course, the device itself is altered.

Hello,
I want to relock the bootloader and go back to stock.
I tried flashing stock firmware using fastboot.
fastboot oem lock begin
flashed stock firmware
fastboot oem lock
But Bootloader is still unlocked.
I got message as first flash full stock system. Something like that. Don't remember as I tried this a week ago.
Any help will be highly appreciated.
Thank you in advance.
Edit : I also tried the Windows tool provided by one of the members but it failed too.
I used the same to unlock in the first place.
I think it depends on what you want to achive. While you might be able to re-lock the bootloader (which means it can't be flashed without being unlocked again), you will never ever get rid of the unlock message again. This - to my understanding - is an efuse which is permanently set. If you want to remove the unlocked bootloader boot message, I'd stay unlocked and would just flash a different boot logo (logo.bin) where the unlocked gfx are replaced with the standard gfx thus showing the standard boot logo.
I would like to relock the bootloader altogether.
I don't think you can. You can lock it but you can't remove the warning that it has been tampered with.
I don't care about the warning.
I just want to re-lock it.
Flashing the Official firmware for my Country - India did the job.
Last time I tried with firmware for ASIA.
I don't see any reason for that to fail but you never know.
Thanks for replying.
hey can you give me the link for that rom im also using the indian version but unable to lock the bootloader
Friends please be careful about OEM lock in an unlocked bootloader.
Since lollipop , google introduced an option in developer menu
'Allow OEM unlock'
It allows fastboot unlock.
Also it prevent unlock while it disable.
The problem is we can't unlock second time after OEM lock.
It makes device bootloop.
My advice is
Don't lock bootloader after unlock.
Don't lock bootloader if your device rooted and/or custom recovery installed.
My phone is in service centre now

Hi everyone,
I have made a terrible mistake... I flashed twrp before unlocking my bootloader. The phone boots then shows a message like "please update to the authorized image", and the get stuck into bootloader, do you have any idea how to recover that, because now we need to login on the phone to get bootloader unlock code and, obviously, I can't.
I flashed twrp by doing, once rooted with kingroot, dd if=/path/to/twrp.img of=/dev/block/by-name/recovery.
When I try to flash with fastboot I get FAILED (remote: Command not allowed), is any alternative flasher available or another way to get the unlock key? I thought about useragent modification to make huawei website thinks it's the phone. So if anyone could send me is useragent by PM I'd be thankful.
I was using lineageos in my moto g4 plus. I wanted to flash stock again, so i did that. my bad I downloaded an update. After that i could pass the bootlaoder it shows an error message "failed to initialize partition table" . Recovery mode is also not working. since oem is locked i can not flash recovery, or any rom. what should i do to unlock the oem and flash a rom?

almost the same here. my girlfriend´s moto g4 entered into bootloop, even though we havent tampered with custom roms, root or anything. so its got everything just like lenovo intented, rom, recovery, everything.
we managed to unlock oem at moto´s website, but since the system doesnt start, we cant enable it from developer options.
the bootloop takes us out of fastboot. and within fastboot we can scroll through the options but cant select any option.
is her phone a brick? or is there something we can do to save it?
we cant afford another phone nor tech service (right now), and she cant afford to be phoneless because of her job. so if anyone knows of anything it could help us a whole lot.
edit: also it doesnt charge
