Sansa Fuze with Rockbox formatted by mistake

My sansa fuze had the stock FW as well as Rockbox. My son booted to Rockbox and accidentally formatted it. Now I can boot only to stock Sansa firmware, but it can play only media from the external sd card. PC also does not detect it.

I want to reinstall Rockbox, but that's not possible as PC is not detecting it. I tried MTP, MSC, AUTO, all failed.

Please help.

I would re-format it using the Format option in the Settings > System Setting menu. That might set things right again. Note, this will also erase all files (music, etc.) that you have stored in the internal memory

Thanks, I did that, but the problem persists. The player charges when connected to PC, and I tried in 4 machines, Win2000, WinXP, Win 7, all fail to detect it, and there's no yellow "?" in device manager. I'm stumped!

Don't know if this will help, but have you tried a different cable? As I recall, there is a 30-pin port on the bottom of the Fuze. If a particular one (or more) of these has bent or broken, it still could be charging correctly, but not making a data connection. The fact that it won't connect to any of 4 machines with different OS's and regardless of USB mode is suspicious and is probably worth trying a different cable.

Re: Sansa Fuze with Rockbox formatted by mistake

First, a corrigendum is called for : I mentioned that my son formatted thru Rockbox menu, it was in fact thru the Sansa FW. Does this also delete Rockbox?

Coming to the cable, well, unfortunately, I don't have another cable to test with and it sure looks OK to me at both cable and device ends (though of course that's no guarantee that its OK). I tried connecting it to my Samsung Galaxy phone thru USB OTG, but it too doesn't detect the player. As I mentioned, the player currently can access only the files in the microSD Card, because the files in internal memory are gone. So my question is can any utility or FW file be kept in the microSD that can resolve the USB problem or even reinstall the FW (stock and/or Rockbox)?

If you format you lose everything on the internal disk, but retain the sandisk firmware and the rockbox bootloader which are not stored on the disk. You can either do a firmware update to remove the rockbox bootloader, or copy a new .rockbox folder to the internal memory.

Re: Sansa Fuze with Rockbox formatted by mistake

Here's what happens when I try to boot Rockbox (without depressing Rewind button on scrollwheel, I switch the player ON) :

 

Screen displays :

 

Loading firmware
File Not Found
**Rockbox logo comes here**

Boot ver 2.0

 

Then, it displays :

 

Plug USB Cable

 

I plug in USB Cable, it then displays :

 

Bootloader USB Mode
File Not Found
Plug USB Cable

 

Does the above indicate that the bootloader is also corrupt. As stated earlier, I cannot access the internal memory, so I cannot "deposit" any file there. What are my options besides trying with another cable (which I do not have)?

No thats normal. You can't boot because you don't have rockbox installed anymore. You need to reboot into the sandisk firmware and either reinstall rockbox or uninstall the bootloader.

>You need to reboot into the sandisk firmware and either reinstall rockbox or uninstall the bootloader.

Can you explain in detail how to do both in my situation?

Thanks
