It could be however little or much you want to rewrite. The firmware uploader seems to only rewrite the zero and first partition, unless you ask it to format the music partition as well. So yeah you could have just a small chunk to overwrite the firmware image, or just the second partition, or whatever. IOW, recovery mode works pretty much the same as regular mode. The only difference is that if your metadata on the music partition is trashed (corrupt smalldb for instance), the Karma will just reboot forever after the Rio logo is displayed, so you never get a chance to mount it in regular mode to fix it, whereas recovery mode doesn't try to read the stuff on disk. > Let me try to understand: you mean that once the dd restore is > finished, it is just a matter of unplugging the RK to get the > firmware copied to the RK flash.

But I don't know how it works. I tried it (from recovery mode), and the Karma switched to the 'Upgrading firmware' screen, but I didn't get the progress bars telling me that it was erasing flash etc. I had to paperclip it after that (luckily it still boots). -- Bob Copeland %% www.bobcopeland.com ------------------------------------------------------------------------- Take Surveys.
