rebug downgrader pup (after using rogero one )
tried installing ofw 3.55
cfw 3.55
4.46 rogero

& nothing

Any help will be much appreciated.

Have you Qa flag your ps3?
Have you verified that QA flag is enabled by going to network settings and pressing the same time:L1 + L2 + L3 (press left stick) + R1 + R2 + dpad_down??
Be sure to enable in Debug settings>System Update Debug> switch to on.
Afterwards, turn off ps3 get into safe/recovery mode install Rogero 3.55 CFW v3.7
