weird rsod problem

hi guys,

m8 got kweam cfw installed the other day and all was running grand.he was playing killzone 3 when the ps3 frooze and could not be switched off unless power at back was turned off.when he switched it on he got the rsod.i tried to sort it by recovery mode no joy there.i then tried to downgrade it from 3.55 to 3.41,all went well,ps3 turns on,you see the wavey lines for a sec then the rsod,but sound plays in background for a while.its a 80gb pal version.it will now not go into recovery mode just switches off.

tried sticking in a non formatted hdd ps3 just turns off,but if i use the original drive ps3 gives wavey lines then rsod.any idea as to what is wrong.is it totally bricked or can it be repaired?

p.s have included an update log from downgrading.

Sorry mate, you need to read through the foums, this has already been asked... I will give you something to search for "nand flash".

Best of luck.
