Chosen Solution
I recently dropped my phone in the toilet, and it still worked for about 4 hours, but then it shut off and wouldn’t turn back on. I put in it rice an hour later and left it in for about 10-14 hours and then my mom said that the battery logo turned on. It charged for an hour and then wouldn’t turn on. I googled it and they said hold the power and home buttons simultaneously for 10 secs, so I did and now it is flashing the apple logo over and over again and hasn’t stopped for 15 minutes.
Hello Haylee, if you read ifixit articles, you will find that you did everything wrong. Rice is not to be used on mobile phones, keep it to make risottos or whatever you like best. The reasons are explained in length here https://www.ifixit.com/News/rice-is-for-…. Also water damaged devices are never to be charged less they will be most likely damaged. My advice is to visit a local repair shop and hope for the best, although according to what you describe I would not expect much, water damaged devices are hard to repair and since this is an old phone it may not be cost effective to repair it.
