How to install TWRP after Magisk? How to install TWRP after Magisk?
I have a OnePlus 6 running Oxygen OS 9.0 and I managed to install Magisk by obtaining the stock boot image and using the magisk manager app to patch it to include magisk, then I flashed the patched boot.img using fastboot and ADB.
The reason I did it this way is that every time I tried to boot with twrp.img in order to flash twrp.zip, I would run into a screen saying Qualcomm CrashDump Mode and TWRP wouldn't boot.
Now I want to install TWRP and I was wondering if there is any way of doing it by using Magisk, so I wouldn't have to boot twrp.img.
Any help would be greatly appreciated.
There is different method from Android 9 and later.
For Android 9 and 10 devices, ensure to disable dm_verity by flashing an empty vbmeta before flashing magisk patched boot. Some devices most especially those using Unisoc chipset require that you generate your custom signed vbmeta.
Sorry, I don't know more but only this difference about Android 9 or newer.
