starts restoring than 3/4 way through it gives unknown error and screen shows itunes on phone. how can i restore without error

You got updated iTunes?

[zedbra]

works with iTunes 10.5

Run Tiny Umbrella, Under General Tab you should see 4.3.3 shsh blob. If you don't see it download from Cydia.
Under adv tab : Select : set hosts file to cydia.
Start Tss Server.
Create a custom firmware of 4.3.3
Put iphone into pwned dfu mode
Run itunes : shift + restore to cfw of 4.3.3

i did all that
half way through it starts saying verifying but the line on iphone is not finished and back to itunes logo on phone

[iYeow]

What error in itunes ?

[darenl]

Error with no number just stops half way and boots back into restore mode

Do you have wifi sync installed on your pc ?

you need to put it in a pwned dfu state. i always use sn0wbreeze and have no probs. if your on mac you can probably use pwnagetool for the same result
