- Enter twrp and flash the system and magisk (can be done using adb sideload).
Note#
According to the description in this article, due to the mismatch of the version number of the security firmware, the screen will lose touch in the Opposite partition's Rec. The official also mentioned this issue, and it can be solved by using the adb sideload method:
First execute this line: adb shell twrp sideload
Then execute this line: adb sideload your_prepared_zip_file_name.zip
Alternative solution#
After flashing twrp img, use adb sideload to install twrp installer, and after installation, enter bl to change the partition to partition a to solve the touch loss problem.
# Check the current partition used by your phone
fastboot getvar current-slot
# Change the partition to B or A
fastboot --set-active=b (if it is partition a, change b to a)

Additional Notes:#
- Method to solve the red exclamation mark on startup: When adb is available, enter
adb reboot "dm-verity enforcing". - It is recommended to flash twrp-installer immediately after flashing the system, and then flash magisk after restarting. This is safer.
