The rear camera of an iphone 4 was broken and needed to be fix. Seemed like an easy challenge.
Everything went smoothly. The guide on ifixit was complete and accurate.
Make sure that the problems is not connectors being disconnected. I had to disassemble the iphone a second time because the problem was not solved. I don't know if it the loose connector was already disconnected or if it was my mistake, but I know that I'll make sure to verify before closing a phone next time!
