Hi everyone! I was going to replace the screen of my iPhone 4s, so I bought all the tools needed for that. I removed the two screws of the bottom of my phone to remove the back cover. I then wanted to unscrew the two screws of the Battery-Connector, which are very small, I removed one, but couldn't remove the other one, it looks like it is stripped. I can't unscrew it. I googled to find a solution, but didn't help much, I tried the following : 1- Using sharp blade. 2- I used a rubber band to unscrew it. None of the above methods did work. In the attachment is a picture of the screw I wanna unscrew, you can notice one is OK and I can remove it and the second one is stripped Does anyone experienced similar situation and was successfully solved? Thanks for any help.
