I've created custom firmware using latest pwanage tool to ensure my bb wont update but get the above error message in redsnow. The IPSW generated is iPhone2,1_4.2.1_8C148a_Custom_Restore.ipsw and its a 3GS phone.

Can you advise best course of action please?

cheers R

um why did you make a custom framwire? r you unlocking? I would have stayed away from making a custom firmware. just bc one it's advise to apple. two there is no way to go make to normal firmware. I would have gist waited till a new unlock came out. and jailbreaking with redsnows is inpossable. with a custom firmware. look into gp to see it will do it. but idk about that one too.

hi there,

I am trying to upgrade 3GS from 4.0.1 without updating my baseband. Instructions below are provided by your colleague knight4u on this site:

You will need the custome firmware (above), the official firmware 4.2.1 (from apple) and redsnow 0.9.6rc8. 1- Prepare the phone for custome firmware (pwnd DFU mode) Run Redsnow (if vista or win7 make sure you run it with Win XP cpmatibility) select the official 4.2.1 IPSW (official not custom) make sure only the boot into DFU checkbox is marked and follow the steps of redsnow. 2- once in pwnd DFU use iTunes to retore to the custome firmware run itunes connet the phone in pwnd DFU hold the shift key and click "Restore" in itunes This will load FW 4.2.1 to your phone but will preserve your baseband 3- Once done you can use greenpois0n rc5b2 to jailbreak untethered or redsn0w0.9.6rc8 to jailbreak (with redsnow the jailbreak will be tethered if new bootrom, it will be untetehred jailbreak if old bootrom) I hope i helped you clarify a few things here.

Im at step 2..
