it stopped charging it dop in to water

@aymen61167 you must treat it the same way as you treat any other water damaged device.

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 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 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. . 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. Do not use drinking water, if you need to use water, use sterile water. Also, 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 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. 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.

The not-charging can be related to a failed charging board (Sub Board) a bad flex cable from the charging board to the main board and of course a bad battery. I would replace the charging board, the battery and the flex if the cleaning won't work. Water damage is a pain and it will always creep back up, replacing the parts eliminates this.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
