I got one DirecTivo hacked completely. Now I have started on my 2nd - a Samsung 404.
I actually had recordings I wanted to save while upgrading the size of the disk. I used mfstools2.0 to do copy everything from one to the other. This took something like 8 hrs.
I then went into Sleepers and skipped the first 2 steps. Surgery went fine, but during the Hack stage it blew up. I believe it could not find a file on the CD for some unknown reason. I rebooted and tried again, but it failed somewhere else. I tried this a few times and kept getting errors. So, I decided to go back through Surgery again. It bombed also.
Anyhow - is there someway I can get back to a pre-Surgery state so that I can re-run everything and not have to go through the 8 hr wait again????
