I just tried jailbreaking a friend's 4.1 3GS and it is now in DFU mode. But when I try to restore the IPSW I built, iTunes says it's going to update it to iOS 5. How do I restore with the IPSW 4.1?

I always jailbreak with the newest OS, so this is a bit new for me.

When you click restore, are you holding down the shift button and then clicking restore?

And have you started the TSS server using TinyUmbrella?

No, I wasn't holding down shift. I just tried plugging in to try it but it won't show up in iTunes and the battery is showing as empty and it's not charging now.

I suggested he wait until iOS 5 jailbreak was out so it'd be much easier for me, but he's concerned with legginess with iOS 5 on his 3GS.

**UPDATE**
Okay, I held down shift and clicked Restore" but it asked me if i wanted to backup (i clicked no), and it proceeded to tell me iOS 5 would be downloaded and installed.

Wondering if I should just restore it to iOS 5 and jailbreak it when the untehtered comes out. How does 3GS run on iOS 5?

Download TinyUmbrella

Start TinyUmbrella

Press the Start TSS Server button

In iTunes, hold Shift and press Restore. It will ask you to choose the ipsw. Choose your ipsw and away you go.

I used Tiny Umbrella, but iTunes still says it's going to update to iOS 5.

Thanks anyway. But, I think 4.1 is too much hassle for me to keep bothering with.
