Thanks a lot man.Terribly sorry but I am not familiar with what you're experiencing. I've never seen that and don't know anything about 30 attempt key anything.
The orange message is that the boot loader is unlocked, have seen that a million times, and there's nothing u can do about that happening.
I did find the needed boot image with magisk patched. I know it says v50 but it's indicated to work with g8 also. Be sure to back up current one and name it so you'll remember what it is and what it isn't
Finally i resetted it successfully.
I think ill try the rooting part tomorrow.
Again thanks a lot man. Ill try with this boot partition tomorrow. Ur a lifesaver. Thanks for all ur replies.
