Hell guys, I recently unlock the bootloader of my red magic 3 global version (NA) but now i want to lock it back, is there any way to do this?
! it just fixed it, ised adb and connect the phone to the usb and open the adb terminal and write: adb reboot bootloader, then use the next command: fastboot flashing lock
nothing more, you're done!
I'm curious to see if anyone else can confirm this with Global version before I unlock bootloader. Thanks in advance.
open recovery mode like before you unlocked and write this to adb
fastboot oem lock
fastboot flashing lock
fastboot oem relock
Once bootloader is locked. Reboot your device with the following command:
fastboot reboot
Its works for me

Hi, I have problem with unlock bootloader in my moto G7 power because my firmware is broke I have Unlock Code from Motorola site when use command fastboot OEM unlock #code receives a message (bootloader) Check 'Allow OEM Unlock' in Android Settings > Developer but I can't enable developer options because my firmware not work, I can only enter fastboot mode. I tried to run developer option from ADB but I have empty list devices even though I have installed drivers Android ADB Interface. I tried to install stock firmware but I need to unlock bootloader first. Does someone have an idea for this problem??
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

Hello all!
I am attempting to re-lock my A30.
I have flashed the stock firmware and unlocked Developer mode and USB debugging
I've tried via adb in the following way (because flashing stock firmware alone did not re-lock)
enter command -> reboot bootloader
phone goes into download mode
enter command -> fastboot oem lock
Phone does nothing and adb Powershell window sits there with "waiting for device"
Any assistance would be magic, thanks so much

After having problems restoring my Lineage OS (TWRP Restore), I found a guide that recommended to do a "fastboot flashing lock" and "fastboot flashing unlock" to delete the data partition. In a fit of mental derangement I did exactly did that. Well, at least the the first part. Stupid move - really. Now I'm stuck with a locked bootloader. I can't unlock it via fastboot commands:
c:\fastboot flashing unlock
FAILED (remote: 'Token Verify Failed, Reboot the device
')
fastboot: error: Command failed
Same results for "fastboot oem unlock".
Fyi:
c:\fastboot oem device-info
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: false
The Mi Unlock tool gives me a charming "Please add your account in MIUI's Settings > Developer options > Mi Unlock status." Which isn't possible because I had Lineage OS running and I can only get into Fastboot now. If I try to boot regularly the phone says "The system has been destroyed".
Well, I almost accepted that I have to dismantle the phone to get into EDL mode, but then I discovered hints that I might need some kind of authorization to update the phone via EDL mode. And a lot of shady offers to do exactly that ...
Did I brick my phone for good, or is there any hope to fix it?
Thanks a lot!
Hi, did you solved it?
If not, try to ut the phone in fastboot mode, then download exactly stock firmware (global, india, china,...etc) version for this phone, then flash it via Miflash.
