OK the way i see it the LV0 Key's allow us to make the boot thing on the PS3 load what ever we want right.
and Because of some LV1 checks the PS3 won't let us install Modified CFW. Though XMB Menu or VIA USB.
so whey cant some 1 make 4.30 CFW and use an E3 Flasher to flash the 4.30 CFW on 4.30 OFW? (or the new 4.31 Firmware) after all your replacing The firmware.
