Touchscreen and LCD not working after reconnection
So I got a working iPhone 3G from my friend, but there was a little dust under the digitizer, so I opened it up and cleaned out the glass, (blow-dryed it out on cool) and reassembled it. Then phone was on while doing this. I also pull a little bit of plastic covering off of the gold part on the top of the LCD. Completely resembled, the LCD/touchscreen doesn't work. Removed/re-installed logic board, nothing. Restored the software, nada. Cleaned the contacts with alcohol, still nothing. It receives calls and the vibe switch works so I know its not the logic board.
I have no idea what i did wrong, I read somewhere that you're supposed to remove the battery. I have no idea what went wrong, everything was working before. help!
Is this a good question?
