Untethered iPhone 3GS stuck in boot

[Dartgh]

So my iPhone 3GS just got stuck in the middle of something and it has happened sometimes, no big deal.. Like usually I just reboot/reset the iPhone and it works like charm... But not today. So iPhone somehow got stuck and when rebooting it just stays on the Apple logo. What to do?

Specs:
iPhone 3GS 4.3.1
Snowbreeze untethered jailbreak
baseband 05.13.04

Never had any problems that my UNTETHERED iPhone would be stuck on rebooting.

What I have done:
General reset
DFU mode
Connected with iTunes -> No results..

Put your iphone into recovery / dfu mode and do a restore again.

Okay. No serious action was needed. The phone was in boot lock for about an hour and suddenly it started working.

Now that your iphone is working, you should go download the latest tiny umbrella and request shsh blob from Cydia.
