Water Damage: Works for a little while...

If there is enough water damage that there was visible corrosion on the board, it is likely that there is similar corrosion under the EMI shields. Removing these shields is not a good idea, as you will likely break the logic board in the process.

Your best bet may be an ultrasonic cleaner. These are often sold as jewelry cleaners, but when used with a high purity isopropyl, will ensure that every microscopic bit of water vapor, and often the corrosion that goes with it, will be scrubbed away.

These can be a bit on the expensive side to get the high quality ones, but if they work, almost all of them are less expensive than a new phone.

Worth noting that I never suggest using these except as a last resort. While they can sometimes work miracles with phones that no longer work, they can just as easily ruin a phone that simply needed to be carefully dabbed out, and put into a bag of rice.

Hope this helps. I chose to invest in an ultrasonic cleaner for my cell phone repair shop, if there is a local tech repair shop around, it's possible they've invested in one as well.

Take the back off the phone.

Take a portable hair dryer and put it on warm.

NOT HOT.

Let the hair dryer blow warm air across the RF shields

and logic board and all the iphone guts for like....a day

or two. It's the hours-n-hours of blowing warm air across

the parts that dries it out thoroughly. The rice trick is good

but it doesn't drive out any moisture. Rice will only absorb

moisture that happens to evaporate into the surrounding air.

Liquids in small spaces may not evaporate easily without

forced blown air.

Take the heat shield off, clean gently with toothbrush and everclear! works every time!

Ok, just experimenting with this-if you take the sharp point of a paper clip and insert it into the little hole on the right middle side of your phone, it breaks it out of "temperature mode". Not sure for how long, but phone seems normal for now. Hope this helps :)
