I got a new phone and lost my photos and twitter account and Facebook account but it says it could still be logged into another phone. It’s the reason i am going back to this phone to get my account back. So would it it work after laying there for a year or so with water damage?
@scarscarlett anything is possible. By now you should definitely find the corrosion on the board etc. since you have nothing to lose I would suggest that you try this. First off you must keep in mind that water damage is the hardest to troubleshoot and to repair. It does not matter if is was exposed for 2 seconds, 2 hours or a year. What matters is where the water (particulates) did the damage. As with any other liquid immersed device you need to follow a few steps for proper troubleshooting. The very first step I would take is to disassemble your phone. Use these guides iPhone SE (1st Generation) Repair to help you disassemble your phone. Take a careful and close look at all components and connectors. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. You will have to remove all the EMI shields. If you do not remove the shields, you are not cleaning the board. Once you got the gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for an Apple iPhone 3G but it is still pertinent to your phone as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on. You do not need to leave it to dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. It would of course be best to get it professionally cleaned After it is cleaned properly and extensively you must replace the battery. This is a must and not an option. After that, reassemble your phone and re-evaluate. For as long as you have not cleaned your board and replaced the battery, everything is just a guess. Of course, you can always post some pictures of what the board looks like etc. with your question. That would allow us to see what you see. Adding images to an existing question
