Tried to fix water damage, but I think I failed.
One of my friends gave me this iPhone 7 Plus that apparently was water damaged. The liquid indicator was red, there were some signs of corrosion, all that.
I tried the standard way to fix water damage, which was to take out the logic board and use isopropyl alcohol and a toothbrush to clean off the corrosion. I tried that with my 70-something% alcohol, and it did work, but only for a little bit. The phone had small text on the bottom of the screen saying "Press home to recover" on a white screen. But it showed that I had to enter the passcode, which I didn't know. Throughout the time, the phone restarted and went back to that "Press home to recover" screen. And then, it happened. This was where I started losing hope drastically.
The phone shut off, and started boot looping.
Each time the phone boot looped, the duration of the Apple logo started going down and down in time, to a point where it flashed for less than 300 milliseconds, and finally, the phone was completely dead.
I believe that I failed to revive this phone, unless if I did something wrong since I have never repaired a water damaged phone before. This is my first time.
If anyone has suggestions, please leave them in the comments or answers. However, I may need them simplified since I don't really understand all the complicated stuff yet.
I just started my hobby for repairing phones, and my first task is to fix water damage on this iPhone 7 Plus.
