Bricked E280, help please?

[joelberg]

I rockboxed my e280 successfully and ran rockbox for a few months with zero problems, I frequently updated to the newest daily builds, until about a couple weeks ago when I updated to the newest daily and my sansa failed prior to boot.  When I press the power button, the blue light in the scroll wheel goes on but nothing will display on the screen, when connected via usb the computer fails to recognize any device present.  I tried the instructions on this page: http://www.rockbox.org/tw...iew/Main/SansaE200Unbrick but my player will not even load into the "recovery mode" by turning on the hold switch and holding the record button then pressing the power button.  Can you give me any pointers or suggestions here?  Maybe I am doing something wrong. 
 
Thanks a lot for being willing to help,
Joel

Connect it in manufacturing mode (see "Manufacturing Mode" at http://daniel.haxx.se/sansa/e200.html)
Download e200tool from http://daniel.haxx.se/sansa/e200tool.html
Download your player's firmware and bootloader from http://daniel.haxx.se/sansa/mi4.html and put them in the same folder as e200tool
Run "./e200tool recover BL_SD_boardSupportSD.rom" (without the quotes) while holding record on the player.
You will enter recovery mode. Copy the firmware and bootloader over (create a blank file called "sansa.fmt" [without the quotes] if you want to format).
Once it is recovered. Run "chkdsk /r" on it.

That should do it.

So you're saying I need to install linux and get a compiler ay?  What distro should I get to fix this problem and nothing else?  I'm not interested in running linux long term, but if I need to get it to fix this, I'd like a suggestion on the best one to run for this and only this.  Or is it possible to get a simple windows c compiler and run it?  Also, which boot loader .mi4 do you recommend?

[Chronon]

Knoppix is a good LiveCD, in my opinion.

[joelberg]

Ah crap I just realized I have no idea which firmware I have on my san disk.  I never updated it ever.  

[joelberg]

Can I use e200tool to put whatever new .mi4 file or do I have to use a specific one?

[zajacattack]

Pick whatever firmware you want, just make sure you download the bootloader that matches that firmware (they will be on the same row in the table on the link I gave you).

Well I'm in Knoppix right now fooling around and I can't get it to detect the player as connected.  I tested my camera and that worked just fine, I actually preferred the ease that it connected to windows.  But not a bleep from my Sansa.  The blue light comes on when I plug in the cable and thats it.  I was also able to run the e200 tool and it was unable to detect the sansa either.

It looks like rockbox killed my player   unless there's something else I can try.

[Chronon]

Are you sure it doesn't do anything?  Knoppix always detected devices pretty well in my experience.  What does lsusb give you?

[Llorean]

Also, please don't jump to conclusions. The problem you're having happens before rockbox even runs. Updating to a new build wouldn't reasonably cause this. Assuming it even could make your device stop booting normally, if your device really won't detect (which is still uncertian since there are tests yet to run) it would indicate a failure most likely of hardware.

Please follow my directions again and tell us exactly what e200tool outputs to you.
