it could be at first that the MM install was corrupt..but it wouldn't go back to XMB without
reporting the "corrupt install" error..and a BARE install is enough to run..but for example if he releases an update..then u cannot skip any update or its corrupted aswell...
like playerkp420, the 800xxx17 error could be from e.g running the DEX version on retail/CEX console = that error/fself.....
if the BD drive would be broke, then installing and running qa_toggle
would also fail..correct?! that other guy got it with "blackbox" only..then i thought...the qa_toggle maybe can run..cuse i'm not sure where it writes to = eeprom or such? but again it would fail on installing with bad BD drive
that other guy with the identical problem on kmeaw, another guy fixed it by a "full format"...he failed at it...now a full format for a PS3 HDD can be done many ways to....perhaps he did not fully format the HDD afterall?!
u could try connecting the HDD to the PC and use the tool "HDD low level format" thats a real great tool to fix HDD problem like e.g OtherOS stuff etc.... but u should not do the "quik MBR format" in the tool but the "full way" instead...it depends on the size of the HDD how long this gonna take ofcourse....it's worth a try....else no clue hehe
just thinking along..
... yes noticed it...sucks indeed..
