What to do when my iphone won't turn on or reset?

I dropped my phone in the toilet about 3-4 weeks ago and it worked fine til now. I was playing an app and the screen randomly went black. I've charged it and it won't even go on to that apple screen.i've tried to hard restore and that hasn't worked.

Buy a new one

Try putting it in DFU mode and restore or put it in DFU mode and take it out

If you don't know how to put it in DFU mode there are many vids on youtube

Don't know sorry

  • Will the MAC address of my iPhone reset if I reset my iPhone to its factory settings over iTunes? I have jailbroken my device and used terminal to change my MAC address so that I could connect to school's Wi-Fi. But when I wanted to change it to its initial number, I typed in a wrong value and it just messed up my Wi-Fi, I can't connect to Wi-Fi anymore. Wonder if resetting to factory settings would help…
  • Reset my iPhone 5s and now it won't turn on? I got a new phone today and someone is meant to be buying this phone tomorrow so i went to factory reset the phone but when i did it went completely black and wouldn't turn on or do anything. I plugged it into my computer and went on iTunes, it told me my phone was in recovery mode and that i need to restore it through iTunes and so i did. 2 hours of waiting went by and when it was finished it said my iPhone was not "eligible". Has anyone else had this problem?
