Problem with jailbreaking 5.01 on my 3GS with Redsnow
I tried to update my 4.2.1 iPhone 3GS with the iPad Baseband to iOS 5.01.
I used the newest Redsnow (build 3), created a custom firmware without updating the Baseband.
Then I set the iPhone to DFU-mode (with Redsnow) and did a restore with the latest iTunes.
After that I did the Jailbreak using Redsnow, installed ultrasnow 1.2.5 to unlock the iPhone.
Everything worked fine so far, but i wondered why the Jailbreak is still tethered.
I thought it should be untethered with the newest Redsnow?
OK, but I could live with that.
But now the big problem:
After restoring the backup with the old settings, apps etc, the iPhone falls in a deep sleep.
Direct after the restore, everything works fine, but when the iPhone goes in sleep-mode after
one minute, I can't get it back to life. Pressing the homebutton has no effect. It seems to be in DFU.
I even can't boot it with Redsnow, when I do this i only get a white screen with some coloured stripes.
Restoring in iTunes brings failure 35.
After that, I did the trick with opening the iPhone and short the golden pin on the right.
That worked, so I could do the jailbreak again. But it ended the same way like before.
It worked until I played back all my data to the iPhone. When the iPhone goes to sleep,
I can't get it to work and I get the white screen when I try to reboot with redsnow.
Can you tell me what I did wrong?
