Rooting (via Magisk):

3. Grab the stock boot.img image for the corresponding NOS version from here (extract the -image-boot.7z file to get it)
4. Open magisk app > install > patch the stock boot image to get the magiskpatched boot.img. Move this patched boot image to your pc
5. Reboot to bootloader.
6. Assuming you have installed fastboot drivers properly type the following cmd:
fastboot devices
fastboot boot <drag and drop the magiskpatched-boot.img>
NOTE:
Using fastboot flash boot at this stage will break OTA updates so make sure you use fastboot boot only!

8. Open Magisk app > Install > Direct install.

Your device is now rooted.
Relocking bootloader:
DISCLAIMER:
Take data backups prior to relocking as data will be erased!
1. Flash the stock rom [Stock ROM Images | Flashing Script | Visual Guide by Techticks]
NOTE:
The above step is mandatory if you are / were previously in a rooted state or made some changes to your partitions. Locking in such a state would brick your device! It is still recommended to clean flash the stock rom once to be safe.
2. After Step 1, reboot to bootloader and type in:
fastboot devices
fastboot flashing lock
3. Select the on-device options via vol and power keys to lock accordingly.
4. Device will be formated and your device will reboot with a locked bootloader.
Your device is now locked!
