So i replaced my screen after it suddenly just went black on me after charging it overnight. Asurion wanted a $220 deductible and they didnt have any s21's in stock so i would be waiting without a phone for who knows. I went on ebay and found an oem lcd screen for $200 and replaced it when i got it. Now, i have "greyed out" service bars and no mobile network detected. 😑 i know my sim card works fine because i put it into any other phone and i have service and data and everything. I tried swapping over antennas from my old lcd to the new one and even with the correct tri wing bit, the screws stripped out. I had to carefully dremel the screws down and pull the antennas out. I successfully pulled the old antenna from the old lcd except for breaking the first screw hole connector, i noticed it has a tiny square connection that is gold in color and has 4 sections. Not sure if that is important, and do these screw holes need to be connected to the metal they are held down to? For a ground or something? If so i was going to solder the holes down because there are now shaved off screws in place of where they should be held down at. I am hoping i just need to reinstall some firmware or something. Ill order a new antenna as soon as i get my paycheck. Sorry if i lost anyone ill post a picture of the "greyed out bars".
