Hi , i dropped my iPhone 4 in the toilet , the thing is that it didnt turn off when i removed it from the toilet, so it kept turned on till the second day then it was off, i put it in rice from 3 days ,and then plug it into the mains,the iTunes symbol shows up and if i remove the iPhone from the mains,it immediately turns off ,i tried restoring through iTunes , but i got an error 1611 .. i tried restoring in dfu mode also i got an error .. some guys told me that its a battery problem and i need to change it,any help ?the iPhone is 15 days old ,and i barely used it,i am so upset :( thanks everyone!
The first thing to do is take it apart and inspect it. Try this guide: iPhone 4 Battery Replacement and then let it dry for a couple of days. A iPhone 4 battery is cheap so I would try that first.
Hi definitely putting in rice will not solve your problem. If it is still under warranty take it back for a replacement. If not send it to a qualified repair tech. This phone will have to be disassembled cleaned up, restored and some parts will need replacement. Sorry. Have a niceday.
The first thing to do is to open the phone. You will need a P2 Pentalobe screwdriver to do this, which can be fond here. You will need a Phillips #000 to remove the motherboard from the phone, which can be found here. Here’s all of the guides iFixit has to help you open the phone. Once you do this, remove the motherboard from the phone. You will want to remove the EMI shields from the phone too, since these are known to trap moisture. With all of this done, soak the motherboard in 99% isopropyl alcohol. You will also want to brush it with something like a toothbrush. Do this for both sides. Once you do this, put the board in a place to dry for ~2 days. Once you do this, he board should be clean and safe to use at this point. There is a high chance of having to replace the 30-pin and headphone flex cable. These very often end up getting damaged in this situation. You are going to have to replace the battery on the phone. The battery will either be compromised or fail in a short amount of time. If you need further reading, here is the water damage guide, which you can follow. You can also follow this guide if you need further reading.
