Hi, I recently became involved in replacing cracked screens for iDevices for folks. I know next to nothing about iOS or any Apple anything but am learning new stuff everyday and loving it. Go Apple! A customer brings me his iPad 2 WiFi/GSM after a botched DIY screen replacement. The volume/power ribbon was torn as was the WiFi antenna. The pins on the dock connector ribbon are smashed with a few missing. I replaced all the above items as well as a new digitizer but before applying the adhesive I'd like to ensure everything works OK. When I power it up the connect to iTunes image is displayed, so I did, on my PC. This was the first time I've ever attempted a restore on anything so it is all new territory for me. To sum up, I've now had this iPad in my possession for a couple months, the customer is extremely patient. I've had numerous error codes during my repeated restore attempts on all the available computers in my home and at my friends, I've learned how to disable security software, everyone I know now has the latest version of iTunes and the last few attempts have given me error -1. I feel this is progress as at least it's the same error over and over and not a different one every time. So a couple days ago my new (refurb) MacBook Pro arrived Yay! I found this forum yesterday and read all eight pages of this thread then joined today. I have followed the tutorial and everything seemed to be progressing but for over 45 minutes the progress bar on the iPad has not progressed, it is stuck at approx two thirds complete and iTunes has been at the Restoring iPad firmware screen. Then finally the -1 error message popped same as during previous restore attempts but this is the first time I've restored from DFU, on a nice, fresh, up to date, working perfectly, Apple Computer and I am curious as to what 'service' the device needs to get past this. The Apple support pages I've read all say after eliminating security, USB, latest versions etc issues then the device may need service but nowhere does anyone expand on that statement. Since first receiving this device I have repaired dozens of cracked screens, replaced several dock connectors, power ribbons, wifi antennas, GSM antennas, pounded out dents, replaced volume buttons and feel very comfortable with the components that make up an iPad 2. Software is still somewhat baffling to me but if its a hardware issue that is preventing me from completing this restore I sure would like to know what it is. Can you help me?
