I see that you can access the device in Recovery Mode.
Let’s try something different. Download the following file: 1.00.12. Connect your e200 in Recovery Mode, and run the executable file. You will see a SanDisk splash screen on your computer, and the program will find the connected Sansa.
This application will install the base firmware on your device automatically.
Once it’s running (after the file transfers, slide the HOLD switch back to the normal position, so the Sansa will start once unplugged), your e200 will be running wiht the base firmware.
You can then upgrade this firmware to 01.02.24, the final version, following the manual installation instructions in the firmware thread. The basic firmware is to get you running; it lacks featues like the custom EQ.
Let us know how it goes!
