iPod touch Itouch 4g 4.3.3 to 5.0.1 (error 21/1601/1602/3194)

Here's the list of the methods i tried but still no success.

1. Tried restoring it in DFU Mode
2. Using Ireb,tiny umbrella
3. already edited the hosts file

anything i miss that might be the solution? and fyi, don't have shsblob for previous ios.

You need the SHSH saved for 5.0.1 to upgrade. Otherwise 5.1 is your only option.

oh i see. 5.1 is only tethered right? so let me get this, 4.3.3to5.0.1=can't be? and 4.3.3to5.1 = yes?

Exactly.

Apple's not signing 5.0.1 anymore. You'll need to go to 5.1

what do i have to back up in case i want to downgrade it again to 4.3.3? just the shsblob?

Yeah. Download iFaith and you can save the shsh blobs for the firmware your iPod is already on.
