PS3 Slim Downgrade Brick

Hello everyone and thank you for this amazing site.
I have one problem with my ps3 and decided to ask for your help.
One year ago i tried to downgrade my ps3 slim from 3.55 kmeaw to 3.41 firmware (custom i guess from ps3 dashhacks if my memory still serves me right)
and i was able to first get it to 3.56 (spoofed i think) and then all hell broke loose i tried to downgrade and suddenly when it was completed
i tried to boot the console the button color went green-yellow and then beeping red without stopping......

Any help or advice would be appreciated.

RED light came out??

is that the signed of YLOD...any good luck fixing...hope somebody will help u here...

did you try to get into recovery mode?

have you been able to put it back into Factory/Service mode?

it is probly still in FSM if he downgraded to 3.41 modified....

put the last firmware (before it brcked) and the lvdiag file on the root of the usb and try to force the update that way, i have fixed many RSOD like this believe it or not.

dunno if it will work, but hell its worth a try
