Problem with cool down mode.

[BoredDude]

well, my phone fell into the toilet yestedey, i pulled it out inmediatly, dried him, and turned it off. I waited 20 min and when i thought it was dry (yes, i now know that it was REALLY STUPID to do that) i turned it on, it booted normally and it works perfectly fine, but after 40-30 min, it enters in cool down mode. Thought it was because it still wasn't fully recovered so i turned it off and on again, but this time 5 min after it booted it entered in cool down mode.
After researching more, i put it in rice and left it all night, when i woke up i tried again, everything works fine, but it enters again in cool down mode in 40-30 min.
The phone doesn't overheat when it enters this mode, however i think it might be because some circuit enters in shock with residual water or is already damaged. My question is, how long should it be in rice ? and if the problem persist, i havel use alcohol to clean the components?

Try using a hair dryer on medium heat on the phone (heat the phone to approximately 40 centigrades by blowing warm air on it. This will generate evaporation and disipation of any water that is inside
the trick is to have the whole phone warmed up .. not just a little in one corner. The rice will absorb water, true, but not "large" quantities.

I waited all day and turned it on again, now this is interesting, the phone seems to be ok, but it entered cool down mode again, instead of turning it off i leave it on and waited, the battery was draining so i decided to charge it, it seems it can't charge from the usb. I turned it and connected the charger, everything normal, but instead of the normal battery metter it shows up an empty battery with an ? on it.
I know the battery is fine because the phone actually responds, but i'm afraid the usb port is damaged.
I connected it to my computer, it appears it has a false contact, my pc recognizes it, and the phone for a seconds shows the normal battery metter, but it goes to the empty ? again.
What should i do?

You have water in the protection circuit of the battery itself. That protection circuit is measuring constantly the battery parameters and currently is reading something wrong.
Al you can do is wait longer ...

If I were you, I would open the phone and dry it from the inside (I opened mine to change the bezel after a drop and it is quite easy). All you need is some precision screw driver set and some patience.

i decided to wait more, so i left it in rice these days. Now, i tried to turn it on, but it won't do nothing, i supposed it was the battery so i connected the charger and left it like 30 min. When i plug it to the charger, the green leed appears and it vibrates, but it doesn't do anything aside from that.
I might open the phone tomorrow and clean it with alcohol, then assemle it again and wait another hours before giving up, really thanks for helping and idiot like me.

You could have removed CoolDown mode *.apk from the system -- but it is risky since as said before something is being read to the system wrong in order to enter in that mode, could be an over current sensor in the SoC that triggers that (maybe by the lowered resistance by the residual water in the system). Good luck!

IT LIVES ! IT WORKS AGAIN !.
I cleaned it and now it works ! Thank you very much !. The only damage was made to the power button, now it's a little bit harder to turn on but i can live with that.
