Restore original image?

I have a HDVR2 that I tried to mod. I went through all the steps, backed up original and burned a CD of it, loaded the U5 kernel, installed BASH ENV, but then screwed up when I got to the ethernet stuff. I didnt really think I would have the Tivo connected to the comp, so I started to skip this part. But some of the next parts require me to have the unit connected. I fear I may have made some mistakes. I would now like to erase my Tivo HD and restore my original or a copy of u5-151-hacked.mfs. I know NOTHING about linux. I need a step by step on how to restore this if anybody has a link or the patience to tell me. I am running windows98. right now I am configured with fat32 as prim master, CDROM as prim. slave and tivo HD as sec master. Thanks

It's covered in Hinsdale.

Probably the easiest thing to do is copy d:\u5-151-hacked.mfs to c:\tivo.bak Then when you boot Linux you can do

mount /dev/hda1 /mnt
mfsrestore -pi /mnt/tivo.bak /dev/hdc
umount /mnt

ok. I have tried this again. I am getting "restore failed: unknown backup format". I have tried the above mentioned commands, Hinsdale's commands, The Complete HDVR2/DSR7000 how-to commands, and variations of all the above. I either get the above message or "no such file or directory exists". Any help would be greatly appreciated and might just save the life of my comp AND my TIVO. Thanks

"No such file or directory" means what it says - you didn't give mfsrestore a valid filename.

Not sure what 'unknown format' means. Either the backup is corrupt in some way, or you're pointing mfsrestore at the wrong file.

When people say 'I followed the instructions', it doesn't give us very much information about what you actually did...
