Is patching the boot.img in magisk mentioned in step 4 an option in magisk? How do I "patch" the boot image?
How do I do this portion of step 5?:
Install the patches boot.img to your boot
Mount opposite partition if A then mount b, if b mount a
Does magisk store the patched boot image somewhere (and it tells you where) that is accessible in TWRP? then we need only go to that file path in TWRP under the "install" tab?
What does this mean?:
And repeat flashing patched boot.img like you did the first time
Do you mean on the partition you were originally on?
So if we're on A, mount B, install the patched boot image on A, remount A, install the patched boot image on B, and then reboot?
How do we "install to th boot?"
Download latest platform tools, canary magisk apk and you'll need the boot.img from the android 10 ota
Copy the boot.img file from the Android 10 zip to the root of your phone.
Install canary magisk, choose to install, install, select and patch file, navigate to root of phone and choose boot.img
Copy the patched magisk_patched.img from the phone to the current platform tools folder (adb, fastboot, etc) on your computer.
adb restart bootloader
Fastboot flash boot magisk_patched.img
Fastboot reboot
You're now rooted.
I only did this once for the active partition and works fine.
