I think you have a chance to get your speaker back.
I loaded a firmware using a different ConsumerUpdate and it KILLED all my internal memory.
I thought it had been finished so I ordered a MiniSD card so I could use my player.
Anyway I used another ConsumerUpdate with another firmware and I got the memory back again, but I lost the screen and I couldn't get into upgrade mode. So I had to do a hardware reboot to get it into upgrade mode, luckily it worked and when I reloaded my working firmware back the internal memory came back again!

It is risky using a different ConsumerUpdate because you could disable your button pad, and then you would have to do a hardware reboot to get into upgrade mode, but I found doing a hardware reboot quite easy and I posted a short guide to show how I did it.

I seems a small part of the firmware is in the ConsumerUpdate install, and it seems to affect the hardware a lot.
