phone got water damage. screen flashing when charging, doesn't turn on
So, I have an iphone 5. I took it with me to kayaking in the lake and wanted to take pictures with it. Unfortunately the sealed bag I put the phone in was not perfectly sealed so water went it and the phone got water damaged.
I dried it immediately when I took the phone out and then put in rice. After 24 hours, I bought some tools and opened the phone, brushed the logic board and all connections with 91% alcohol. The logic board does not look corroded at all. It looks pretty. After that, the phone worked perfectly! I also had an incoming phone call right after that and it worked just perfect. All apps seemed working fine as well. However, then I was too excited and was stupid enough to plug the phone into the charger...
After 2 minutes est, the phone shut down and I immediately unplugged the phone. After all that, the phone won't turn on and whenever connected to charger, it starts flashing screen with apple logo. When I connect it to my Mac, the screen starts to flash and iTunes will recognize my phone whenever the phone is in restoration mode.
Now I am getting a new battery for this phone and hope it's the battery that is fried. I really hope the logic board still works. Any suggestions? What exactly happened?
I will appreciate any help!!!!
Is this a good question?
