[Android Central Question]

okay so this is a bit complicated but im desperate and i would appreciate all ideas!

i rooted my redmi 4 prime a few weeks ago and it worked very well and i was super happy. but yesterday i did something really dumb, i accidentally clicked on a system update and the update removed my root access. i really want to root it again but since i rooted my phone my computer doesnt rcognize it anymore. i read that thats a common thing and its easy to solve - if you have root access. so now i dont have root, i dont have twrp and i dont have mtp/adb.. how can i solve this? it feels like a vicious circle..
if anyone has an idea on how to fix the connection problem without root access or how to root it without a pc connection (i already tried kingoroot) please help..
