I found my bricked Sandisk Sansa E250 in a pile in the basement. I thought I’d give it one last try to get it going. After much faffing about, I found that applying this fix – Corrupted version.txt/Fw update not working in recovery mode? The solution !!! – Sansa e200 FAQ – abi>>forums (which resulted in a failed boot saying something about an mi4 not being found) followed by Recovering a bricked Sansa had it working with the fairly awful Sandisk firmware. So it was off to Rockbox for the latest version.
I have to say, Rockbox 3.4 is pretty neat. They’ve now got proper USB reading/writing/charging, so that you never have to see the clunky Sandisk UI again. When plugged in, the player acts as a USB keyboard for controlling your music. Apparently the E250 can now support MicroSDHC cards, which it couldn’t before. But best (and least useful) of all, is that you can play 3D Deathchase and other ZX Spectrum games on it …
