Hi,
Plz help me to solve this problem.
I have an iPhone 3Gs 8gb i recently downgraded it to 4.1. Now i want to upgrade it to iOS 4.3.5 but i have no SHSH blob saved for it and i think theres no need of shsh blob for upgrading... So when i tried to restore it in dfu mode by deleting the line gs.apple.com in host file it gives the error 1600 then i used ireb and again do the restoring but now it gives error 21.. What should i do...
And how i do the restoring from ios 4.1 to 4.3.5?
