First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 2: Enable USB Debugging and OEM Unlocking on Nubia

Next up, you will also have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking process.

So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.

STEP 3: Boot Nubia Device to Fastboot Mode

3. Type in the following command in the CMD window to boot your device to Fastboot Mode adb reboot bootloader
4. To verify the Fastboot connection, type in the below command and you should get back the device ID, as shown in the image. fastboot devices
5. You may now proceed with the steps to unlock the bootloader on your Nubia device. Follow along.

STEP 4: Unlock Bootloader on Nubia Device

1. Unlocking the bootloader on Nubia devices is a little bit different. You will first have to get hold of your device’s model number as it will be used in the unlock command. So search it online from a trustworthy site and copy it down somewhere.
2. Now execute the below command in the CMD window. Make sure to replace the ModelNumber keyword with your device actual model number: fastboot oem nubia_unlock NUBIA_ModelNumber
3. For example, if you’re planning to unlock the bootloader of Nubia Red Magic 3 whose model number is NX629J, then the above command will transform to: fastboot oem nubia_unlock NUBIA_NX629J
4. As soon as you execute the above command, you “might” get a confirmation on your device. So use the Volume keys to select “YES”/”Unlock the Bootloader”/or any other related options and press the Power key to confirm it.
5. Your device will now undergo a wipe and subsequently, its bootloader will be unlocked.[Facing Issues? Check out the FAQ below].
6. Finally, you may now use the below command to reboot your device to the OS: fastboot reboot

If the aforementioned command didn’t manage to unlock the bootloader on your device, then you may try using any one of the two universal unlock commands listed below [Case 1 or Case 2], or the combination of the universal command+Nubia Unlock Command [Case 3].

1. [Case 1] First off, try this command: fastboot oem unlock
2. [Case 2] If that didn’t work out, then try using this command: fastboot flashing unlock
3. [Case 3] If both the above commands didn’t work out, then you will have to execute the below two commands, one after the other: fastboot oem nubia_unlock NUBIA_Model Number fastboot flashing unlock
4. For example, if you are unlocking the bootloader on Nubia Red Magic 6, then the above commands will change to: fastboot oem nubia_unlock NUBIA_NX669J fastboot flashing unlock
5. As before, you might get a confirmation message on your Nubia device. So use the Volume keys to select Unlock the Bootloader option, and the Power key to confirm it.
6. The unlocking process shall now start and could take a couple of minutes. Once done, you may reboot your device via the below command: fastboot reboot
