Poorly functioning home button on a nearly 2 year old iPhone 4. It was either try to fix it or cough up the skrilla for a new phone
It went well except for breaking the corner off of the logic board. I didn't realize there was a specific guide for the Verizon version and I missed a screw hiding under some tape. I managed to piece it back together and everything seems to work fine so I guess I got everything grounded sufficiently.
Like the video, having a screw tray or separate cup for each step's screws makes it so much easier to get back together.
Also, the logic board comes out much easier if all the screws are removed...
