Hi

When a device is water damaged the best thing you can do is work fast!

So the first thing you are going to want to do is unplug the battery and completely dismantle the phone

Here’s a video guide you will need

Once fully dismantled you will want to clean off any corrosion with a soft toothbrush some cotton buds and some isopropyl alcohol

I would also help to have it taken to a reputable repair shop to have it put through a ultrasonic cleaning bath

If you have cleaned it and you still have no luck on getting it working have a look for any components that look damaged(burned ,cracked,loose,discoloured)as they could need replacing

Like I said if it sound like a lot or too much for you I would have it seen to by a professional as it will raise the chances of survival

Hopefully this helps

Any questions please ask

Thanks:-)

Hi albert,

Well, unfortunately I can't offer you a lot of hope here, as salt water is very bad for electronics. First off, do not try to turn the phone on or charge it until it has been cleaned!

About the best you can do at this point is to either take it to a repair facility that is experienced in liquid damage for a thorough cleaning and repair, or you can see about doing that cleaning yourself. You'll need to be comfortable completely disassembling your phone, cleaning it and putting it back together. Here's a Wiki on what to do when your electronic device gets wet.

You'll need to take the phone apart and clean everything. Here's a teardown for your phone that should give you what you need to know.

One final note: Buy a new battery! Salt water is extremely conductive and has probably destroyed the battery, and if it hasn't already, it will.
