Re: MBR/Flash problems = dead V2?

So, you didn't successfully flash recently?

If you hold F1 when you start it up, it should load any ajbrec.ajz in
the root directory. So you should be able to load Rockbox by doing
that. Then just "play" either rombox.ucl or rockbox.ucl. Don't know
about updating the bootloader.
