iPhone 5s bootloop after waterdamage repair
I have an iphone 5s that went through the washing machine about last year in august and was sent in for repair one day later, and it was fixed and worked fine, but last month, this phone started to enter bootloops ramdomly. For the first 2 times that it entered bootloop, I could get it out by connecting it to itunes, restoring it and praying for error 9 or error 4014 to not appear, but now it is completely stuck on “looping” between the apple logo screen, a black screen and a off screen and is not detected by itunes. I know a logical person will probably buy a new phone at this point, but I want to know if it is a small issue like a bad battery or something that I can fix for cheap or if it is something like a dead logicboard. Thanks!!
I forgot to mention that occasionally, the phone exits bootloop and works for about 10 seconds to 5 minutes.
