SBSettings messed up 3GS and won't reboot
On a 3GS with 3.1.2 that was jb'en and unlocked using blackra1n, I have restarted and tested it with t-Mobile several times and everything worked fine.
First app that came in mind to install was the SBSettings from Cydia. After installing SBSettings it showed the message that it had to reboot: It shut down then restarted showing the apple logo. It displayed the logo for 10-15 seconds then went to a blank screen.
I've connected it to a pc with usb cable, same thing happens, tries to power up, lights up the logo for a while, then goes to blank screen. Pushing the Power button again repeats the cycle.
Appreciate any help, am pretty much out of ideas. I've just upgraded from an iPhone 2G and am fairly familiar with these steps but nothing worked so far.
Thanks in advance,

It is not SBSettings that caused your problem but a common system enhancer that is required by SBSettings.

Yes, it is generally a good idea to take a backup before upgrading thongs like mobile substrate. It pays to take note of all the packages to be installed not just the main package.
