You broke it!! I’m telling Mom!!!
Nah, I have a theory for you. As long as this is a v1 device. Do you remember if the splash screen, when you power it up, looks like this?
The v1 has a recovery mode. The v2 is different, less susceptible to this issue. Remove the back of your machine, careful that you don’t lose the four wee screws. At the top of the device, you’ll see a large black rectangular area. Within this area, press down gently on the grey rectangular foam block. This will reseat the memory module. The v1 can “lose its mind” if the daughterboard isn’t properly seated.
Let us know if the Sansa springs back to life after this check. If there’s nothing under this black area, you may have a v2 device, but again, the “blue ring of death” is common to the v1. Does the device power up when plugged in to the USB port?
Let’s take things one step at a time. There’s plenty of information nestled in here about recovering a dead v1 with e200tool , but it isn’t for the faint hearted. Hopefully, the issue is simpler than having to recover your I2C ROM.
Let us know if the device responds. A word of caution!! NEVER attempt to format the device using the Windows Format function, while in Recovery Mode.
