Hi; I got some problem I hope someone can help me out, I have a 3g iphone, with firmware of 4.2.1 on it, locked and jailed, when I got it, I did unlock it since i could not use it otherwise, I used Resn0w 0.9.6b6 ( it was couple of months ago), the jail breaking and unlocking went smooth and I was using my iphone since then, since the baseband has been updated to 6.15, then Gps was not working and I was aware of that, time to time I searched online to see if there is any solution to make it work. somewhere it was solution that if I downgrade to 3.13 it is possible to make gps work, so i did follow the instruction as using the os 3.13 to update iphone with itune and use 3.12 with Redsn0w 9.4, so I did and got the iphone with cydia installed, tried gps for couple of hours no chance of working. so i decided to get back to Os 4.2.1, since I used a software to backup and noticed that I can not use my backup while using 3.13 on my iphone, so decided to get back to the 4.2.1, but can not make it work, hopefully someone can help my out, my intention is to use itune to restore to 4.2.1, and then use Redsnow 0.9.6b6 to install the cydia on the phone. I managed to load the 4.2.1 to itune and iphone started to restore, but then i get an error that the iphone could be restored an unkonw error, error 3014, and iphone stays on a recovery mode ( a circle itune logo with a usb icon) I have tried couple of times, there is no problem when i use os 3.13, but with 4.2.1 cannot be restored and giving an error. I also used 126.96.36.199 gs.apple.com on my host file when using 4.2.1. I use pc running win xp sp3. anyone know why I can not get back what I had? Thanks for help.
