This "4.23 jailbreak" was a modified version of a SEX firmware, 4.23 is the firmware on demo consoles in stores.
That's why all these "jailbreaks" resulted in people stuck in demo mode..
NOTE; No PKG's were signed for this firmware either, it was simply a scam to get kids to download this update JUST because it has the option to install package files.. All it did was suck kids into being stuck on a demo firmware.
