I have been trying to repair a lot of rsod systems most L01 models which suck. I have fixed several that had bad sectors in the CVTRM.
For some reason the l01 models while I have found bad sectors in the CVTRM and edited them it still did not fix the rsod. I am able to get them all to 3.55 rsod bypass fw but they dont play games and upon installing ofw 3.55 they go right back to rsod. I have ran both rsod repairs on them but still no luck. I read a member by the name of Susoft is very good with the rsod.
