Chosen Solution
I ordered kit for replacing my iPhone 4S battery. While following the guide, I came to know that the screw head of bigger phillips screw inside is damaged and the screw driver keeps spinning and it is not letting screw to come out. Please let me know if you have a solution for this.] Thanks in advance!
I use these small pliers for screws where I can grasp the head: Screw Extracting Pliers The screw extractor set is good for screws that cannot be gotten to used the pliers: Precision Screw Extractor Set Using a Demel type tools with a cut-off disk to make a single slot for a flathead works well.
