    @ Sharon January 22, 2012 at 6:46 am I have found the solution! You have to edit your hosts file! I have put an # before a Apple server, and that did the trick. See option 2 here for details: http://www.ipad2iphone5.com/how-to-fix-unknown-error-when-restore-iphone-4-with-itunes It is possible though that you should alter the hosts file with one of the other 2 suggested options. Good luck!

I rename the hosts file again to original name. only problem now is that I don have an network which I can see my carrier but reflect no carrier list....

    I had the 1604 error message on my iPhone 4 with 5.0.1. firmware and ran the program and now it's successfully custom restoring! Thanks so much!

    I followed instructions here and on RedmondPie. Typical advise is to launch iTunes, enter DFU, close iTunes, iReb, launch iTunes then shift-click restore. Gave me an error every single time on 3G and 3GS.When I entered DFU without being in iTunes, I was able to get it to work every time. If you keep getting 1600 errors, try skipping step 1 of opening iTunes first.When it would work, I noticed two things:1) Entering DFU while not running iTunes, my computer would install a driver (recognition of device despite already being plugged in). If entering DFU when iTunes was running, it would not install the driver.2) While iTunes is "preparing to restore", the screen will flash, then display an install progress bar.

    No results, here. I've tried this as well as other methods (Tinyumbrella, holding down Home and plugging in, moving the "C:\Program Files (x86)\Common Files\Apple\Apple Application Support" directory, etc) and nothing seems to work. I have an iPhone 4 with iOS 4.2.1 and 03.10.01 Baseband. I've looked everywhere I can and there doesn't seem to be an answer that works for me. There has to be a way or at least an explanation why it doesn't work.
