This news can concern both versions of Blacksn0w and iPhone 3GS users.
Some users have seen that Blacksn0w works during a certain period with their iPhone 3GS and then one day, the iPhone crashes and reboot in loop.

The issue seems to appear because of a corrupted baseband.
Even with a Custom Firwmare 3.1.2 with Blacksn0w, the fix is not solved !
Then, this only concerns iPhone 3GS with Firmware 3.1.2 and baseband 05.11.07

Here is a method to try to solve this issue. And, if you have not recover your ECID thanks to Saurik, it can avoid you to restore to Firmware 3.1.3 !

Required :
  • Transfer with SSH on your iDevice these 3 files in /tmp.
  • With iTunnel Suite, start Putty.
  • Identify : su root
  • Type the password by default : alpine
  • Type these following command lines :
  • cd /tmp
  • chmod 755 BBUpdaterExtreme
  • launchctl unload /System/Library/LaunchDaemons/
  • ./BBUpdaterExtreme update -f ICE2_05.11.07.fls -e ICE2_05.11.07.eep

Wait for the update (few minutes) and then reboot your iPhone 3GS by typing "reboot" in Terminal or manually by pressing Home+On buttons together.
