S21 Ultra bootlooping after screen replacement
Hey all, I'm new to the forum, but I'm dealing with a rather big issue.
I replaced the Display (and the battery since my kit came with one) on my S21 Ultra and everything worked fine for a couple of days until suddenly it started to bootloop. However, I get to the lock screen for a few seconds before it restarts which seems strange to me. Online, I was told to replace the daughterboard for some reason, which I then did and made sure to reseat everything. Phone worked fine for the next few days, and then it started bootlooping again. Any pointers on what the issue could be? Thank you!!!
