Hi, my son dropped my iphone in toilet couple months ago. I got a new one, but I wasn’t able to retrieve all my pictures and video, even some documents that were stored on that iphone. After carefully reviewing all the visor an guides I decide to repair iphone myself. I got a new battery and cleaned logic board, watch the YouTube videos and repeated all the steps. So far after putting it together iphone is still not turning on, but I feel the back of it getting warm. It’s was doing same thing before I start repairing it. Is it completely broken or still have a hope?!
I have the best success rate fixing water damage on Iphones compared to any other phone and would say to use this guide and try fixing it again, Repairing iPhone Liquid Damage, the guide is for an I3 but use the same methods on your 4, also I would say try a sonic cleaner to take it one step farther, try taking the logic board to a phone shop that has a sonic cleaner or take it to a jewelry store that does sonic cleaning, with the logic board out of your phone it shouldn’t cost much to get it cleaned, if these steps don’t fix it then you would be looking at changing hardware on the board, good luck, If this Answer is helpful please remember to return and mark it Accepted.
Well I’ve been having the same problem and I was experiment with my 4s all night. I’m now at a point where the phone oscillates between this overheating issue, and a flickering yellowish display. I solved the overheating issue after fully disassembling the phone. When you remove the circuit board you will notice a spring contact which is meant to bond the board to phone’s body. In my case I found it be compressed therefore there would be no contact. You just need to pull the contact beyond its normal position to ensure contact when the board is replaced. When reassembled correctly the phone should turn on fine. As for my flickering yellow display issue. I’m willing to take the fault there. While going over what I’ve done it noticed my mistakes of scratching and slightly bend the digitizer connector leads. I’m still trying…
