Hi all,

As the title says on itself, I tried to update iphone 3G with iOS 4.2.1. I followed the onscreen instructions and now the phone is not working.

Your help is really needed.

Thanks. Josef

Do a hard reset: Hold power + home button until the Apple logo appears. If it goes to Recovery Mode (USB + iTunes screen) restore with iTunes and then jailbreak with other means. You can try redsn0w Monte if you have 4.2b3 or 4.1 SHSH blobs.
If it boots normally, just do Monte. If you haven't SHSH blobs, use PwnAge Tool or Sn0wBreeze (recommended, but requires full system restore. Better than Monte).

Just restore to stock 4.2.1 and then use Redsn0w 0.9.6rc8 for an untetheerd jailbreak, forget about shsh talk,you'll never need them, you'll never need to downgrade to jailbreak coz 4.2.1 is jailbreakable and you will always get 4.2.1 restore signed via itunes as it's the end of the firmware update road.

The only thing that can put a spanner in the works is if you have or take the ipad baseband for service, then you'll have to restore to custom 4.2.1, but still no need for shsh's for that.

Yep but Monte (the last time I checked) needed 4.1 or 4.2b3 SHSH blobs on saurik's server. No 4.2.1 support.

What's Monte got to do with it?

Thanks all for your great help. I did a restore of the whole phone and restored to 3 days ago.
