Not sure, what to do now? Starting with flashing TWRP again? If you can imagine, what I could do wrong, please let me know
Same issue actually.The only time I could install Magisk with Evolution ended with a boot loop. This was the the situation, when a button appeared left beside "add zip" to add Magisk. I saw this button never again, and when I try to add Magisk with the menu, I get the message in red, that it is missing.
