A few days ago I used the rockbox utility (v1.2.13) to install rockbox on my sansa clipzip. (I forgot which radio button I clicked for the version to load, but I believe it said that this was the recommended choice). I tested it for a while and everything worked fine. The text was too small however, so I loaded the "runners" theme which fixed that problem. I turned the brightness to max since I usually need only a few hours before recharging. Then I deleted the music, added perhaps 5 or 6 new albums, refreshed the database, and went on a run. It said 90% in the top left corner (which I presume is battery life remaining) when I started. It played the first album great and was about half way thru the second album when it suddenly stopped. Blank screen ... couldn't restart. Also unsuccessful booting to orig. firmware. 30 second power button reset also failed. My computer no longer recognizes it as a clipzip, but it shows up as a drive letter. However it says that it must be formatted before use.
Did I brick my device, or is there a way to recover from this? Should I try to reformat and if so, should I use a FAT32 quick format? Would the rockbox utility then work or would a manual install be required?
I'm not using an external memory card, although I could get one if that would help. I'm not adverse to taking apart the device if that turns out to be necessary.
Thanks in advance for any help you can offer.
