It's an iPhone 4, J/B and unlocked. I used it for 1 month in Europe with no problems whatsoever. Now it's stuck in the recovery mode (the plug to iTunes pic). I tried fix recovery 43 and redline.dll (I think it's called) to boot it out of recovery mode but I get a message on my phone saying that "cannot fix or find"... something. Tried that twice. I finally got it to enter DUF mode. I am trying to restore it using tiny umbrella but I seem to be getting the 2005 error. I switched the cords, tried a different USB (using Windows btw), I repaired iTunes and still getting the 2005 error. I have no idea what else to do. Please help.
