This means that TWRP will not allow modifications to any of the partitions that make up the Super partition on the stock ROM. All backups and restores will include the full Super partition rather than the individual dynamic partitions.
In order to flash the individual partitions, you will have to boot into fastbootd.
Current and past versions of TWRP can be found at one of the mirrors below:
If you already have TWRP installed: Download the latest img/installer and flash the image using TWRP to both slots, or simply flash the installer.
If you do not already have TWRP installed: Download the img. You will need to have fastboot binaries and the correct drivers installed. Power off your device completely. Hold volume down and turn on the device. Your device should now be in the bootloader. Connect the device to your PC. Open a command window and run the following command from the proper location:
fastboot boot path/to/twrp.img
This will temporarily boot TWRP on your device. At this point - if OOS is installed - it’s recommended to take a backup of the current recovery as it will need to be restored for incremental OTAs to install successfully. Now, either copy the TWRP installer zip to the phone and flash it, or go into adb sideload option from the booted twrp and execute the following command:
adb sideload path/to/twrp-installer.zip
Note: OnePlus 8T is a Virtual AB device with dedicated recovery partition. So, flashing TWRP will not mess with root or boot partitions, unlike the true Virtual AB devices like Pixel 5, Poco F3, etc.
