In the spirit of honesty and candor, I have an iPad 2 16 GB WiFi with a busted display glass that I've been using with an iOS 5 beta 4 build that I paid 10$ for online. I know it's my own fault for violating terms etcetera but I still want to ask the community for tips as this is still a good iPad. 5 days ago (Aug 7) I noticed that the system wasn't downloading apps I chose to install from the App Store so I did a reset with the Home and Power buttons, releasing the power button but continuing to hold the home button once the white Apple logo appeared. At this point the device flashed to black and started displaying a few lines of code in white text on a black background and then it rebooted to the "Connect to iTunes" screen with the picture of the cable and the iTunes icon. I have iTunes 10.5 beta 4 and iOS 5 beta 4 installed. I use an iMac 20" C2D Late 2006 with Snow Leopard and all the latest updates. If I attempt to restore normally, I get the error 1604 message. If I put the device in DFU mode and restore normally, I get the error 1600 message. Sometimes it gives me the error 3194 message but mostly 1600. If I use the ALT+restore option and select either the stock 4.3.5 or the 5b4 ipsw it still fails with 1604. I've tried on other computers with the latest stock version of iTunes but I get the same errors. As it is now, the device will get so far as to begin the restore process but it freezes with the Apple logo and the spinning wheel (not the beachball from OSX) and iTunes halts at "Preparing the iPad for restore". After a few minutes, error 1604. Any ideas or hints are welcome, as I really don't want to be without this iPad, broken though it is.
