A2017 How to unlock BL after relock

Hi all,
I've unlocked my A2017 Chinese bootloader,
Installed TWRP and B29 base rom.
Everything worked great until I made a mistake and relocked the bootloader.
Now the phone just showing the ZTE blue logo and turn off.
I can boot to the bootloader with holding both volume up+down but when I try to oem unlock it i get:
FAILED (remote: oem unlock is not allowed)
The system is not booting so I can't allow oem unlock from developer menu.
What can I do?
Thank you in advance.

Hi, you need to flash the bootloader accepted recovery.img first. Download the latest B13 chinese official rom and extract recover.img. Use the command to flash it:
fastboot flash recovery recovery.img
Then reboot to this official recovery, and flash the B13 official rom. Now you can restart your previous bootloader unlocking process( actually I have no idea of how you succeed on the A2017 model). Good luck!
----second thought:
I doubt if you can successfully execute the command
fastboot flash recovery recovery.img
since your bootloader is locked. Just wish you good luck!

Help please, endless bootloop

I have tried downgraded my phone from nougat, but has ended in at bootloop only showing the red Huawei Logo.
Now i can´t enter recovery, can´t update using 3 button method only thing i can access is fastboot.
My problem is my bootloader is locked and therefore i can´t flash an recovery. And now i cannot figure out how to obtain my product key, so i can unlock the bootloader.
Any1 who can help me with this would be much appreciate.

What did you do exactly to end with endless bootloop?

I used the rollback file from this Thread:
https://forum.xda-developers.com/hu...torial-rollback-n-to-mm-c432-devices-t3563955
Update went fine but afterwards it ended in a bootloop. The only thing i can access is fastboot.
The weird thing is that in fastboot it says my bootlader is unlocked with red, but i cant install an recovery. Its says acess denied and ask if i'm sure my bootloader is unlocked.
And thats why im back to trying to unlock the bootloader but i cant get the product id for my phone when i can't turn in on.. seems hopeless

I suppose that you did 3 button update metod. You have to factory reset phone. Press volume up and power button together and keep pressed until you see erecovery option for factory reset phone. Do it.

I cant. Have tried all the button combinations to enter both recovery and update mode but nothing works, only vibrates and showing huawei logo. Only thing i can access is fastboot through computer

With huawei extractor extract (from B160 or what ever firmware is your phone) system, boot, and recovery img and flash with adb. Than you have to do reset.

Thanks for the suggestion.
When i try flashing it with adb it starts writing but then says "Failed (remote: Command not allowed)
Should have installed the proper drivers but still not working.
Same thing if try flashing with the L31 toolkit. Here it says "Something went wrong! - Maybe your boot-loader is locked?"
The only thing i can think of, is trying to unlock my bootloader again and see if its work. Even though it says unlocked in fastboot mode. But for that i still need the product id for my phone which i can´t get???

unlock bootloader code is not eligible for that IMEI (14 days limit...)
anyway, if you can not enter in fastboot mode, you can do anything...
go to service center or try DC Phoenix via a small fee (10-20 euros)...

i can enter fastboot, what next?

I have entered fastboot. It said phone unlocked, FRP unlock. Then, what else I have to do?

for unlock code you have to login your Huawei ID atleast 14 days...
i suppose you can't do that...

relock bootloader

Hi,
Can I relock my bootloader while TWRP is installed? I want to get OTA updates back as I am not getting them because of the unlocked bootloader..

To relock the bootloader you have to flash the oeminfo.zip or use the dload method to install stock ROM

You must have stock recovery...
A booting system..
Your bootloader unlock code...
Make sure you can boot to your system first:
1.Do a factory reset using stock recovery
2. immediately after doing the factory reset go to bootloader and relock your bootloader
fastboot oem relock xxxxxxxxxxxxxxxx
3. Boot to your system and go to developers options and enable oem unlocking
If you try to use TWRP for the factory reset you will brick your device
It has to be the stock recovery.

Cannot boot Mi A1 after locking bootloader

Hi could I ask because i lock my bootloader on Mi A1 but unfortunately the device didn't boot up.
Now, I am trying to unlock bootloader to fix my device and it won't unlock FAILED (remote: oem unlock is not allowed).
I am on May latest security patch build. Please help me.

Did you try reflashing ROM with Mi Flash tool? Use "Save user data" option there.

I think you tried to lock your phone after rooting your device. You'll have to try to switch to fastboot mode by volume down + power after vibration. Then use flash using Mi flash tool

I cannot do that, the bootloader is locked and I am on May security patched. Those fastbook oem unlock and fastboot flashing unlock methods won't work. I believe only testpoint is the solution to my problem.

Stuck with the exact same problem....did u find the solution

Reboot to fastboot power+volume down then reboot to edl mode by typing "fastboot oem edl" in your adb your phone will turn black. Open miflash and click "refresh" if you see "com#X" it means its connected then flash the fasboot file you downloaded in mi forums after finish press and hold power until it restarts.
