Sansa Clip+: connects to PC but looks bricked

(1/1)

sdf5:
Hi,

I have a Clip+ that looks bricked (no signs of life) but it is recognized when connected to a PC, see below. Any suggestions what I could try to get this Clip+ working?

Thanks


# echo "This is a NON-working Clip+"; fdisk -l /dev/sdc

[Saint]:
The 4MB storage being presented is the classic symptom of a bricked Sansa AMS player.

All we know about the "recovery" (you'll see why I refer to that in quotes later on) procedure for these devices is listed in the SansaAMSUnbrick wiki page.

The wiki page seems to suggest that the procedure is straightforward, or repeatable, or reliable. It isn't. In fact, its none of those things. Hence the quotation on "recovery".

If you decide to attempt this procedure please make sure to do so while actively communicating with us on our IRC support channel for live, realtime assistance. If I am present and available at the time I would be happy to walk you through the process.

Thanks, I'll see what I can do.
