Hi!
What happens if you don't have permission to unlock bootloader and you still try to do it using fastboot oem unlock on Xiaomi Phones?
I have already got the permission and I've rooted my phone, so I didn't really try it because I was simply afraid. Has anybody tested that?
Also, if I relock my bootloader again using fastboot oem lock, will I be able to unlock it using fastboot oem unlock or will I have to use MI tool?
Aaaand the last question - I haven't installed custom rom or TWRP - I booted TWRP using fastboot boot xxx.img, then installed SuperSU package. Is it dangerous to lock bootloader with phone rooted? Recovery is still stock, so ....
Hi guys,
I got a bootloader unlocked ANE-LX2J and I want to lock it again but I dont know the next step.
I still have the bootloader unlock code and already flashed FULL OTA using TWRP and did factory reset.
So now, my P20 Lite is running pure stock again and ready to be locked right? or still not lol :silly:
Based on what I read here, after relocking bootloader using fastboot oem relock command, the warning/alert that shows when the device is booting is still there and I want to get rid of it.
Thanks :highfive:

Yes, you're ok to relock your bootloader if all partition and recovery are stock and your device is working without issues. After relock the recovery will do Factory Data Reset and no more warnings "your device has been unlocked and can't be trusted"
Boot into Fastboot&Rescue Mode and use this command:
Code:
fastboot oem relock [I][B]yourcode[/B][/I]
Then you enter into Lock Bootloader menu and just follow the instructions.
YES -
NO -

Does the Lock Bootloader menu will automatically show after relock command? I'll give it a shot later. Thanks :highfive:

Yes, if your code is correct.
If my phone was rooted, will relocking the bootloader unroot it?

it will show a red text saying your system has been tampered with and turn off..
you will need to restore a completly stock rom with sdcard before you can boot the phone.

I accidentally relocked the phone by using the hstool method of flashing a full firmware.
it does relock the phone and required me to unlock it again using the fastboot oem unlock code

That's interesting. So all your data was wiped when you used the hstool?
Someone else said flashing firmware via dload method also relocks the bootloader.
hmm i'm not sure.
I'll explain the whole situation.
I had just unlocked the bootloader and installed magisk.
after installing magisk, I installed a few modules, one of which made my phone bootloop.
I managed to get back into fastboot mode, use hstool to select my firmware (224) along with the patched hisuite from funkyhuawei.
after my phone recovered, it seems to have been completely reset and locked.
*edit*
I guess I should also add, I've never installed TWRP on this phone, only patched the recovery_ramdis.img for Magisk

After locking, can you use the same code to unlock it again ?

Yes
ok just an update, while mucking around I accidentally softbricked my phone.
I used the external usb method (where you update using the code *#*#2846579#*#*) and it 100% relock the phone.
*edit*
and yes, the same code works to unlock it again. KEEP THE CODE SAFE!

You need an external usb-c drive with some firmware on it.
I initially used v187 from this thread
https://forum.xda-developers.com/mate-20-pro/how-to/firmware-update-187-brings-oem-unlock-t3897301
Since then I downloaded a v206 which works over USB but I cannot recall where I got it from.
Note that you will loose all user data since the phone will be fully wiped.
Also this method requires a phone that is working, as in able to boot and access the dialer and menus.
If I find out where I got the v206 I will post it here as well.
I should also add, maybe it might work with a memory card as well... But this method requires an external source for the firmware since it formats the entire phone
@ xeroxide Thx for your help.
I Try this at the weekend.
If you need to relock your bootloader, this is the process:
Using eRecovery, restore your phone to stock
Once done, boot into recovery and RESET your phone (if you dont, it will not allow you to lock the bootloader)
Boot into fastboot mode (Holding Vol-DOWN, plug in usb cable) , and run the command
fastboot oem relock < bootloader unlock code>
the phone should now ask you that it will wipe your device, confirm,
Enjoy locked phone!

this worked for me thanks loads!
to relock the bootloader I tried the "fastboot flashing lock" command without quotes via adb pc fastboot the device will ask you to reset the system once you start the phone go to the developer settings and deactivate the 'unlock oem' check then restart and play original device is made for future joyui11

After my bs2 enters boots mode the system doesn't not recognize again.... It give error waiting for any devices
I already unlocked my device once and flashed a custom rom but due to issues in custom rom, I reverted back to stock MIUI and relocked the bootloader with
"fastboot OEM lock"
Now i can't find any methods to unlock the bootloader again and it shows error "token missing" in ̶m̶i̶ ̶f̶l̶a̶s̶h̶ mi unlock tool when I try to unlock bootloader again.
