deleting mman or incomplete cant make the ps3 not boot anymore..right..then it would
be the first time, mman wil only report the build is not supporting the firmware(04.18.00)
then update from mman/online or offline to 04.19.00, base or full, only installing an "UPD" would result in a incomplete/corrupt mman install
the only things i can come up with..even tho its going down after 3sec? with beeps?
pull/switch the power completly at the back of PS3
put back power cable/switch ON
quikly press after eachother on frontbuttons "power+eject" and see what the PS3 does, if lucky it does its magic and goes into FSM (the PS3 shutsdown by itself after awhile) so dont do nothing til its OFF (gives no beep), reboot into FSM.....if it boots ofcourse...this is atleast the way to "trigger" FSM on this 4.31CFW exitout with 202kb lv2diag.self
