Completely Wiped Fuze-No Better Than A Flash Drive

[Just1MoreThing]

Well, I have a 8gb Fuze that was originally a FuzeV2.  I'm not sure what it is now, seeing as I (because I temporally had no brain ) deleted everything off of the player.  That includes the .rockbox folder and the fuzpa.bin file.  So now it's basically just a 8gb flash drive.
A short history of how this occurred:  Everything is sunny and wonderful.  Then my player with latest version of rockbox on it shows that all the folders on it are empty.  No music, no audiobooks nothing.  This can not be because when I plug in the player it shows that all the files are still there and they play, on the computer that is.  The player is functioning just fine except that there is no way to play anything.  I try everything, changing themes, deleting all info, putting info back on, nothing works.  So I delete everything off of player.   Then I try to reinstall rockbox.  It says it can't install without the original sansa bootloader.  O.K, I put a fuzpa.bin file (for V1 fuze, I also tried V2) on the player along with the bootloader-fuze.sansa file.  Then I put on the .rockbox folder on the player and start it up.  Full of hope I look at the screen.  Rockbox screen appears briefly then comes the black screen with white letters saying 'loading firmware file not found' then 'bad checksum' with a bunch of numbers that disappear before I can write them down.

Basically I just want a list of 1,2,3's that will give me some options.  I really don't want to spend $35 again for another player.  I know this one works I just need to figure out how I screwed it up.  Actually I really don't want to know that, I just want to know how to fix it.
Thank you!

Probably installed Rockbox for a different player then the one you actually have. Go back and reinstall the correct build.

That includes the .rockbox folder and the fuzpa.bin file.

The file fuzpa.bin is only required for updating the firmware on the player. You don't need to keep it sitting around once you have installed the bootloader.

No music, no audiobooks nothing.  This can not be because when I plug in the player it shows that all the files are still there and they play, on the computer that is.

Sounds like you accidentially set the "Show Files" setting to "Playlists".

Rockbox screen appears briefly then comes the black screen with white letters saying 'loading firmware file not found' then 'bad checksum' with a bunch of numbers that disappear before I can write them down.

As saratoga said, this usually happens if you installed the wrong build. I recommend to try Rockbox Utility's autodetection (but make sure to delete the wrong .rockbox folder first, since it otherwise will detect the existing installation and assume that to be the correct one, which isn't the case).

Thank you for answering so quickly, but I have tried to do what you recommended and it's not working.
1. I used the rockbox utility 'device' then 'change'
2. I selected the player (E:/) then clicked 'autodetect'
3. The message 'Could not detect a mountpoint. Select you mount point manually.'
4. So I picked the Sansa Fuze V2 (Stable) version.
5. Went into instillation tab, clicked 'install the bootloader'
6. Now it said (roughly translated) that I needed a copy of the original Sandisk firmware (bin file) and that I needed to download this file myself.
7. I clicked on the links in this pop-up and downloaded a fuze02.03.33.zip file from http://daniel.haxx.se/sansa/amsfw.html.
8. And there was the bin file.  I put it on the player, then tryed the bootloader process again.  Now it works, and I go to the 'install rockbox' under the installation tab and install rockbox the stable release. However I noted that it says that the latest stable release is 3.11.2 and I used the fuze.bin file for 2.03.33.
9. Now the .rockbox and the fuzepa.bin are on the player good it should work right?
10. I turn off the player, and turn it back on.
11. Now the rockbox screen comes up saying it is 'Boot Ver 2.0' but then...
12. All this comes up:
Loading Firmware:
Length: 9E398
Checksum: 3F4CF40
Model name: fuz2
Loading rockbox.sansa
Sum: 3F4CF27
13. Then 'Plug USB cable' on a black screen.  When I plug in the cable it says 'Bootloader USB mode'

So what am I doing wrong?  I though I just had the wrong .bin file for the version, but I downloaded the latest I could find.  I just need to know exactly what I should do. :'(
