Jailbroken iPhone stuck on apple logo after reset

So I erased all content and settings on my iPhone 3G on iOS 4.1

Now it is stuck on the apple logo and won't show up in iTunes.

I've tried tiny umbrella but it doesn't show up in there either. Redsn0w does see it when I put it into DFU and attempts to rejailbreak but at the end it still doesn't work.

Any ideas?

Thanks, but it doesn't show up in iTunes. Even when in DFU.

Hi intell,

From the stuck apple logo I hold down the menu button for five seconds, then both the sleep and menu buttons until it turns off. Then I start iTunes with the iPhone plugged in, hold down the sleep button for five seconds, then both buttons for 10 seconds, then let go of the sleep button. Nothing happens. If I do the same in redsn0w the iPhone will enter DFU. (I just tried it and now it's trying to jailbreak again.)

Thanks einmusiker.

I tried that and it came up with the
connect to iTunes graphic. I think that means it's in recovery mode and not DFU? But anyway it's further than I got before.

iTunes still didn't recognise the iPhone but a dialog box did pop up saying iTunes couldn't connect to server. So I connected to the internet and tried again. This time iTunes detected the iPhone in recovery mode and I attempted to restore to a custom firmware I made with PwnageTool.

The process seemed to stall saying "preparing iPhone for restore" and then an error popped up.

I'm going to try putting the iPhone in DFU again but make sure I'm connected to the internet.

Redsn0w will try to jailbrake the phone (and fail) immediately after DFU.

Pwnage tool normally works better to get the phone into DFU but...

At the moment the phone is stuck in recovery and even after kicking it with tiny umbrella it goes straight back.

Update!

I finally managed to sort it out. If it helps anyone else here's what I did:

• reinstalled original iOS 4.1 from iTunes
• used most recent redsn0w 0.9.6rc8 to put phone in DFU
• restored to custom iOS 4.1 I originally created in Pwnapple
• downloaded ultrasn0w from cydia
• restored settings in iTunes
