@ebstventer56504 you are not telling us if you did anything about the water damage. Letting it dry and hoping it will work again is not a good strategy.

For now, you must stop continuing to try to charge, sync or otherwise use your phone. This potentially can make a bad situation worse. This may further damage your phone. The next thing to do is to clean it.

The very first step I would take is to disassemble your phone. Since ifixit does not yet have a guide for this phone, use something like this video to help you disassemble your phone. remove the main board and the charging board. You will have to remove all the EMI shields. If you do not remove the shields, you are not cleaning the board.

Take a close look at all components and connectors and 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. . Once you got any 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 all the steps are 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 the boards 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 ultrasonically cleaned Do not forget to replace the battery. This is a must and not an option. It will fail if you do not take care of it now.

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.

In your case you want to pay particular attention to the connectors for the front panel. Make sure those have no corrosion, damage etc. You will have to consider replacing the display assembly, since it may have gotten damaged through the water immersion. If the cleaning and a replacement display do not fix the issue, then you are looking at failed components (short circuits) on the main board. That would require board level repair. Unless you have the special tools, schematics, and experience to work on this, you may have to consider finding someone that does board level repairs.

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 or 2 hours, what matters is where the water (particulates) did the damage. Most repairers do not take on water damaged devices due to the low chance of repair success.
