I am trying to upgrade to 6.1.3 from an iPhone 4 on 5.0.1 with BB 01.59.00 and got Unexpected Error 2831. I tried fixing it holding Home Button through all the process, I didn't get the error but Redsnow never finished and I got stucked on Recovery Mode (itunes logo). Any ideas how to fix it?

I also got "Couldn't restore" "Unexpected error (2831)" and my phone came back on just the way it was before I began. I'll keep scoping this out to see if there's a fix. I will also try using firmware 6.0 instead of 6.1.3 and see how that goes. I'm running iPhone 3GS 4.2.1 Modem Firmware 5.13.04. Thanx
