I meant 'System Update Debug' was one of the QA flag Debug Settings which is reset. Sorry for the confusion
Well we already have that, lv2 patching with bdemu.bin. lol just kidding, do you mean like the X360key. I haven't heard of any devs working on something like that.
Just a question, how many people are actually using my dev_flash for their FW 4.00 ps3s. I just want to know if someone has found it useful.
