Please don't PM asking for help again. That's against forum rules, and I really don't want to go reporting people to the forum mods.
As for your problem, try this out. It's a little long, but it should work.
1) Reset your iPod by pressing MENU+SELECT, then as soon as the screen clears and the Apple logo appears, immediately click the Hold switch to boot into the Apple firmware.
2) Connect your iPod to your PC, and try running iPodPatcher again.
If it works, you should be able to uninstall the bootloader. If not, then take these additional steps:
3) Temporarily reinstall the Rockbox software again from a current build.
4) Let Rockbox boot again, then connect your iPod to your PC.
5) Uninstall the bootloader first, then delete the .rockbox folder second, and then eject and disconnect your iPod.
If it still doesn't work, PLEASE don't PM me again. Just reply to this answer in the forum thread.
