I have iPod Touch 4G with 4.3.5 with iTunes 10.5 (last version) and I'm trying to update to iOS 5 through iTunes.
- All updates (Windows and iTunes)
- Firewall / anti virus protection disabled etc
- all USB devices disabled
- rebooted pc and ipod many times
I tried both update button and using the ipsw file, but I always get the same file. Tried on two computers, one win 7 x86 other win 7 x64 - same problem.
EDIT: Looks like for some reason (probably because I installed tiny umbrella) I had the redirect to cydia hosts file. Removed, problem solved.
What could I do?
