Requirements:
- To Unlock Bootloader On Nubia Red Magic 3 (NX629J), you will need a computer.
- Charge the Nubia Red Magic to at least 50%.
- You need a USB cable to connect your phone to PC. (Users reported better luck with usb 2.0 port vs usb 3.0.)

Connect your rm3 to your windows 10 pc without developer options enabled. It will be a cd drive, and you can double click it to install the usb drivers

1) Enable the Developer Options
- To Enable Developer Options, Go to your Settings -> About -> Software Information -> More -> Now Tap on the Build Number 10 Times until you see a toast message “Developer options enabled“

2) Go back to settings -> Now you need to enable the OEM Unlock by going to Settings -> Developer Options and check the box for OEM Unlock and USB Debugging

3) Connect your phone to Computer using USB Cable.

4) Open a command prompt window on your computer and type: "adb devices"

5) You will see a pop up window on your phone to allow USB Debugging on your phone. Click ok.

6) Now type the commannd "adb reboot bootloader"

7) Once your phone has rebooted into it's bootloader, type in the command prompt "fastboot devices". This will list the devices connected, your phone should show up.

8) Then, enter "fastboot oem nubia_unlock NUBIA_NX629J"

9) Then enter "fastboot flashing unlock"

9) Finally type "fastboot reboot" into the command prompt.

10) From here you can install twrp, root your phone, etc.

TO RELOCK BOOTLOADER Restart into fastboot on your phone, and use the commands:
"fastboot oem lock"
"fastboot flashing lock"
"fastboot oem relock"

Sure thing! I'm assuming you have access to fastboot & are using windows.

Download the right global rom for your phone: https://eu.redmagic.gg/blogs/news/red-magic-3-global-rom-flash-instructions

Once you've downloaded the rom, extract the folder. Use the following commands.

cd "path of folder" (example: "cd C:\Users\Worldchamp\Downloads\NX629J_Z69_EN_WPJ0O_V111") - dont use the quotation marks.

fastboot oem nubia_unlock NUBIA_NX629J

fastboot flash parameter parameter.img

fastboot reboot

fastboot oem nubia_unlock NUBIA_NX629J

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash splash splash.img

fastboot flash modem NON-HLOS.bin

fastboot flash system system.img

fastboot reboot

So what I do if there is no system.img after extracting to flash?

On global rom, the fastboot flashing unlock does not work... even if i change ports from 3.0 to 2.0... The TWRP is available only for China rom ? On Global does not work ?

LE: Make sure you have latest ADB Drivers 1.43, after i updated to these, the flashing unlocked worked
