First thing's first, what SHSH blobs do you have saved for that device?

They are signature files for any one particular IPSW for any one particular device. They are absolutely essential for getting proper restores of iOS device's firmwares. Originally Posted by Narusada

EDIT: Error 3194 is Apple's code for "no SHSH blobs."Last edited by Orby; 01-13-2011 at 10:45 PM.

Restore to iOS 4.2.1 from DFU mode (custom firmware preferred) and then jailbreak (if necessary) from there. Originally Posted by Narusada

EDIT: You ran "Save ALL SHSH" with your phone plugged in via USB, and it didn't even show iOS 4.2.1 (8C148) or (8C148a)?

can i download a similar shsh blob for my phone or are they all unique?
i have a 3gs but isnt there only tethered jailbreak for 4.2.1 i tried that with my itouch and the tethered jail didnt work. i want to unlock my iphone too for tmobile.... and i know how to do all of that for 4.0.1 down but there is no way to downgrade with no shsh files?

No SHSH files, no downgrade. The SHSH files are all unique per-device, so if you don't have them for your phone, you're SOL. Originally Posted by Narusada

We can preserve your baseband (and thus your unlock) under either circumstance with a custom PwnageTool firmware--if you cannot make one yourself, I can link you to one.

Run redsn0w 0.9.6RC8 and only check tether boot and watch this video to get your iphone up.

Why do you want to do dfu mode, you are stuck at apple logo right ? It is because you update some essential stuffs in cydia and needed a reboot, a tethered jailbreak will sometime end up in apple logo.
