My Sansa Clip+ suddenly started having bad checksum errors during boot

If you can mount the device and access files on it, I would just download a build and copy it over.

However if the Sandisk firmware is also having trouble, I don't think a new build is going to help.  It sounds like something is wrong with the player, computer, cable, etc and not the software.

dpitch40:
The behavior when connecting it to a Linux machine is the same: Autodetect freeze the Rockbox utility and "ejects" the player when connected with crashed Rockbox, and doesn't detect anything when connected with the original firmware running. I'm starting to suspect I'll need a new player, so I may as well just try reinstalling Rockbox on it, right?

dpitch40:
Totally uninstalling Rockbox, updating the Sansa firmware, and reinstalling Rockbox seems to have done it. The .m4a files no longer seem to be causing problems.

Ambush:
I had a similar problem, fixed after rebooting into original sansa firmware, formatting storage, then reloading rockbox.

I had this same problem and this worked for me too. I rebooted into original Sansa firmware (using Power and left buttons pressed together). I backed up everything on the Sansa first. Then I went into settings and formatted it. Then I used the Rockbox utility to reinstall from scratch. Everything worked then, though it was obviously all new settings and so on.

I also was able to get my original settings back in an interesting way. Just to see what would happen, I copied over my backed up .rockbox folder. When I did that, the errors came back. Not a surprise. Something was bad in that folder. Then I went and ran the Rockbox installer utility again. This time it went quickly and it seems like it just reinstalled whatever file needed fixing and left the rest. Now it's working just as it did before with all my settings but with the error fixed.

So if you have this problem I recommend first going in using the Sansa firmware option and backing things up. Then try just running the Rockbox utility on it and it may just fix what isn't working. If not, then do the whole process and format it, reinstall from scratch, copy over your backups and then run the Rockbox utility one more time.
