Doesnt worked. I read that i need to now format my hdd. How do i do that whitout other ps3

Because the fw is so messed up that it wont let me overwrite it

Dang. I wouldn't know what the problem is then? Hmm, have you used a different downgrader?

You have to toggle qa Before installing the v3.7 3.55 cfw.

Already done that and didnt work then. Problem solved now by changing the hdd
Thanks for tips still

My geusse is that you were on cex and your trying to get back to dex?

easy fix just install the right firmware.

what you are doing is right, just using the wrong pup.
