CPU heats up a lot and smells weird
how did this ISO bath info get around.?
its a cruel hoax of BAD info.
this trick might have worked for someone somewhere, but as a default procedure for anyone who dunks and iphone? !&&* no. Best thing is if you have the means of taking it apart is to VERY CAREFULLY remove the batter connector from the main board and send it to your nearest repair facility.
The "chip" that you knocked off was probably something very important to the performance of the phone. whatever the case this now beyond your capability to fix.
my feeling is you damaged the main board by trying to run it too soon after your ISO bath. whatever they how, it dosent matter. its pooched.
