please help me to unlock the bootloader again,
My RM3 was already bootloader unlocked,
at developer option, the Oem Unlock switch was grayed can switch on or off,
when check on fastboot, Device State - Locked
Your bootloader is still unlocked. It just means everytime you wana flash something through ADB you have to send first the following code:
Code:
fastboot oem nubia_unlock NUBIA_NX629J
.
My bootloader is unlock my rom is global latest 2.15 Everytime I fastboot flashing lock my rm3s. my device always gets corrupt.. how to lock it properly? or is there any other tricks or fastboot commands? To properly lock the bootloader again
After successfully installing MIUI EU and using it just fine, I then attempted to lock the bootloader as the phone is going back tomorrow for a screen repair. Upon using the command fastboot oem lock in fastboot mode, the bootloader was locked, but I am now in a bootloop returning me to the fastboot screen no matter what I try. WIth my bootloader locked adb does nothing and same with most fastboot commands. Whenever I try to reboot my device regularly or while using any combination of volume buttons, it shows the MIUI boot screen then straight back to fastboot and repeat.
Any help appreciated, thanks.

Strange idea to want lock bootloader for repair a screen. Even if you must send to Xiaomi warrantly center / agreed shop, unlock bootloader do not cancel the warrantly. Only desimlock is forbidden.
You must lock your bootloader only from your native official/legit ROM (EEA or Global or CN, etc), but never from a custom MIUI or AOSP because these roms have need to have bootloader unlocked for working.
For now you must
1- using Mi Unlock and Unlock again your device, like the first time (from waiting unlock period) but you will lose all your data, data partition (internal) is wiped.
2- using MiFlash for flash the lastest MIUI fastboot legit rom from your device (EEA ? Global ? CN ?) and be careful , by default (on the bottom right) app install / erase and lock bootloader, choose install / no lock.
I managed to fix it by using Mi Unlock with my sim in another phone for verification, I was just worried I would be faced with the wait again. Thanks.

No problem, as soon as you have unlock with success your bootloader the first time, you do not have period unlock anymore
I was trying to install Pixel Experience rom for my device.But when I flash the recovery image of pixel experience it was not installed and I was stuck in fastboot mode.Then I tried to somehow the Pixel Experience recovery load and phone go in a loop show logo poco and restart again and again. The fastboot mode did not coming after that i tried to install a rom using sp flash tool and it was not worked but fastboot mode now coming and I now tried to flash using miflash tool it shows boot in lock state.My bootloader was locked again somehow. Then to bypass this I used some python commands and unlock the bootloader and using flash I flashed my original rom but after that, another problem occurred like google and mi account not being connected google services not working, and mi account also another thing was ok. How can I solve this.?please help. I can't use google services and can't log in mi account also. My OEM unlocking status permanently on it doesn't have an edit option. I used these files to unlock the bootloader.I follow this article
Load the MTKClient: https://github.com/bkerler/mtkclient
After the install (drivers are needed for windows / using linux is preferred) type:
"python mtk da seccfg unlock"
and connect the device (off) with vol- and vol+ buttons pushed.
You may have to use the command "fastboot flashing unlock" or "fastboot oem unlock" in fastboot afterwards.
Good afternoon everyone I have a problem with my redmi note 9, when I try to unlock the bootloader and then enter fastboot using the keys on the phone as written in the program procedure mi unlock does not detect any phone, while when I enter fastboot from android using adb reboot fastboot not only do I enter another version of fastboot but the phone is identified with a read error, how can I solve this?
