Once again a maybe silly question. Yes, I already tried the search.
I have bought the 4K mantis stick and unlocked it. But on the last step, where I have to execute sh script to boot to twrp (and flash magisk), I had to stop there, since I had a problem with my laptop. That's fixed now, but how can I enter twrp again? Do I need to do everything again, since i don't have su permissions?
