So I don't want this for PSN at all now that Rebug has enabled PSN again and will not be using it for downgrading period. I am grabbing all my content since launch day again and disconnecting from PSN. What I do want to do is preserve my flash as I switch from Cobra to TB at least twice a week. Now I know there were problems with Cobra after hardware downgrade, what I am curious is once I install it I just need to set one bank for one CFW and one for the other correct without the need to dump my flash or anything like that right? I am going to make a backup just to be safe but I have debug updates enabled so no system updates from the dash but you never know with Sony being sneaky with adding updates to the latest Bluray disc. Anyhow what is the best tool to verify I have a working dump? Or should I just keep dumping till I have a matching set via MD5?
