Hi All,

New to the game but successful unpack the boot.img from the stock firmware (.pac). 

Copied boot.img to the tablet, applied magisk patch the boot.image (said successful).

Copied file back to PC and flashed boot.img with Research tool, said successful but stuck in a boot loop.

Flashing back the stock boot.img fixed the boot loop.

What step am I missing?
