[Android Central Question]

So i tried to update my system
And after downloading and waited for it to complete i says update failed . I tried to reset everything but its still stock at bootscreen (startup).

Yep
Im rooted (coz i need it)

Now wut do i do

will it work if i....or is it possible to unroot my phone even though i cant open it..so it wont fail whn trying to update it.. [sorry not really good at English] ▪

will REPROGRAMMING fix everything?

Thanks ♡
