I bought a 1+6t (8+256) on the small yellow croaker (the screen fingerprint is damaged). I wanted to install win11, but due to hardware problems, every time I installed it, it was stuck in the state shown in the picture below, so I wanted to check a different system.
This problem can also be solved
Press and hold shift+f10 (or shift+Fn+f10), enter regedit, find the registry HKEY_LOCAL_MACHINE\SYSTEM\SETUP\STATUS\ChildCompletion\SETUP.EXE, double-click it, change 1 to 3, and click "OK". Close the Registry Editor and click OK on the error message box. The computer will restart, and then the problem will be solved, but after entering the system, many drivers are found to have problems, so they give up the installation. If you want to flash win11 arm, you still need Xiaomi mix2s
First prepare the 9008 rescue brick package
So I chose lineageOS 20, which is equivalent to android13
LineageOS Downloadshttps://download.lineageos.org/devices/fajita/builds
Download both packages from the official website.
In addition, it is really convenient to unlock the bl lock of OnePlus, just open the developer option, turn on the unlock switch, enter fastboot and run fastboot oem unlock
After entering the fastboot mode, flash into the recovery image
fastboot flash --slot=all boot boot.img
fastboot reboot recovery 
Then enter the recovery interface, this is made by lineageOS itself, not twrp
Install via adb sideload
adb sideload lineage-20.0-20230309-nightly-fajita-signed.zip 
Then restart, and then hit data reset.
