[OnePlus Nord 2T] garylawwd:
Hello everyone hope you are all keeping well.

Here is a little guide on how to Unlock/Lock the Bootloader and Root/Unroot our Nord2T.

I cannot be responsible if you brick your device. Your phone, your choices, your responsibility!

​

Unlock The Bootloader;

​

If you haven't done it already...beware that this will erase all of your user data. To do so, you must:

Enable developer options

Enable the "OEM unlocking" option

Enable USB debugging

Have both adb and fastboot, from SDK Platform Tools available on your PC

Connect your phone to your PC using the USB cable and run the following commands:

adb devices

(just to make sure that your phone is, in fact, recognized by your PC and that you're able to run adb commands)

adb reboot bootloader

(so your phone will reboot into fastboot mode)

fastboot flashing unlock

(device should now unlock)

fastboot reboot

(device reboots with an unlocked bootloader and data partition wiped so set up the device from scratch again)

Rooting Guide;

​

Unlocking the Bootloader is necessary before continuing​

1 - Download Nord2T stock boot.img that you may find later on this post,

that matches your current build

.

Copy the boot.img to your devices internal memory

Leave a copy of it on your PC (on the same folder you have adb and fastboot...you never know if you will need to use it again in the future...to restore the stock boot.img, aka revert to stock...)

2 - Download latest Magisk Manager from HERE and install it on your phone

3 - Open Magisk Manager App and press:

Install

Select and Patch a File

Browse to the path where you saved stock boot.img and select it

Magisk Manager will now patch the boot image and store it in [Internal Storage]/Download/magisk_patched.img

4 - Copy the patched boot image from your device to your PC (Store it on the same folder where you have adb and fastboot)

5 - Flash the patched boot image to your phone by running these commands (remember, you must have patched boot image on the same folder you have adb and fastboot and, of course, your device must be connected to your PC...)

adb reboot bootloader

​

fastboot flash boot magisk_patched.img

​

fastboot reboot

​

6 - After the phone boots up, hopefully with a normal boot (almost feels like nothing happened....), install/open Magisk Manager App again and watch Magisk doing it's magic!

7 - Enjoy!

All credits goes to topjohnwu and his incredible work with Magisk.

System Updates;

​

For system updates. Just apply the OTA update as normal.

Once updated you will have no root and you must follow steps above again with the new boot.img that corresponds to the firmware version you are on.

Unroot;

​

To unroot simply flash the stock boot.img.

Relock Bootloader;

​

If you have TWRP installed flash the stock boot.img (same as your firmware version from earlier in this post)

This is so as you can access fastboot properly.

1 - To relock Bootloader first download Oxygen Updater app from the Playstore.

2 - Download the firmware which corresponds to the firmware which you have currently installed.

3 - Move/copy this firmware.zip to your PC and extract it. (inside you will see a folder and a couple files. The only file we need is payload.bin)

4 - Download/install Fastboot Enhance on your PC

5 - Reboot phone to bootloader mode so it gets detected by Fastboot Enhance, from there boot to fatsbootd.

6 - Flash payload.bin in Fastboot Enhance

7 - Wipe data in fastbootd from your Nord 2T, reboot and finish phone setup.

8 - Enable developer options, enable USB debugging from developer options.

9 - Reboot to bootloader and run the command;

fastboot flashing lock

The device will be now successfully locked.

Hope this helps out 🤙
