^_^ Ok, I just released
AutoDowngrade Generator V1.01
Like I said I would, here is the new release (Version .01), which now lets you upgrade to 3.10 OEA from 3.03 and below.
I also added an option 0, which lets you just get the files needed for upgrading to the new firmware, 3.10 OEA.
^_^ This needs the update eboots, so find:
1.50 Eboot, rename to 150.pbp, move to CoreData
2.80 Eboot, rename to 280.pbp, move to CoreData
3.03 Eboot, rename to 303.pbp, move to CoreData
3.10 Eboot, rename to 310.pbp, move to CoreData
Also, I had a hard time grabbing the 3.10 firmware due to the number of people trying. If you are having issues, try these mirrors:

One more thing, if your just downloading my file to update, you can create two fake files and call em 280.pbp and 303.pbp, and the continue like normal to speed up download time. My package is more like a tool to help others.
