Fixed water damaged iPhone iTunes error 9?
I purchased a week ago a water damaged iPhone 6 (it has a little crack on the glass too), the device didn't turn on at all. After cleaning the Logic board with contact liquid and changing the battery with a New one, the device fortunatly did show some sign of life!
Now the problem is, when I turn it on the apple logo appears for 2 seconds long and then I get a black screen with backlight on. I tried connecting it with the latest iTunes version (it says the iPhone is in recovery mode) but trying to restore it is unsuccessful due to error 17. I tried to restore it with my laptop with an older version of iTunes and after starting the restore iTunes gives error 9 (hardware problem I suggest) and the iPhone screen gets red for a second. I tried kicking it out of recovery mode with iReb and iReboot but it keeps looping the recovery mode.
Any ideas/tips on how I could fix this before giving up and re-selling it? Thanks in advance.
