I haven't done anything with the partitions. I'll go through in detail.
Began with 20GB stock DMS.
Backed everything up.
Followed procedure from Windows Hack Procedure linked above.
When I first inserted DMS after hack, the unit immediately booted into normal mode and started playing the first song on the DMS.
I checked the logs and here they are.

I tried again by reinserting the DMS and it began working and kept rebooting and giving me a "no cartridge found" error. I expected this and kept changing back to the phatbox source, but it happened at least 50 times and never changed. The logs didn't change either.
I tried one more time but right after I inserted the DMS I accidentally unplugged the cable.
Ever since then I can't even switch to the phatbox source and when I plug in the DMS the lights start up and both blink forever even after I remove the DMS until I pull the plug.
I used my backups to restore the DMS to how it started and get the same thing. I then updated the firmware, same thing. I then reapplied the hack, same thing.
