When i disconnect the power after sucessful flash without errors, and then power back on with power and eject (with a PS3KEY dongel connected that has the right files on it)
My system just power on for about 2-3 sec then shuts it self off, and all off the lights goes out aswell.
And i have tried to restore with my original 3.73 backup NOR (witch is error free, checked with NOR Dump Checker) but the problem remains, power on for a few seconds then powers off and power button light goes out.
the ps3key puts it in service mode and shuts down after a few seconds this is normal
why the red light shuts off is a mistery to me
the next step should be the actual downgrade to 3.55
did you try to use the usb stick with lv2diag.self and the ps3updat.pup files after you have put it in service mode with the ps3key?
