I bought an allegedly "water damaged" phone off of ebay (iPhone 4 16GB VZW), but upon taking it apart, none of the water damage indicators were red. They were all white. I cleaned the entire logic board with contact cleaner nonetheless, and reassembled everything. iTunes will start the restore process, but when it gets to the screen that says "Waiting for iPhone" in iTunes, it freezes. The progress bar on the iPhone is empty, and it doesn't move. I've tried pwned DFU with redsn0w, Jailbreaking it to 5.1.1, restoring to 6.1.3 in iTunes and redsn0w, and I've combined that with performing the custom IPSW restores with tinyumbrella running to allow the custom firmware to be loaded - but nothing works. Any hints as to how I can get this thing going again? I've been searching for about 4 hours now, but can't find anything relevant.
