Question about SanDisk Sansa c150 MP3 Player
This isn't a full solution yet, but I found on rockbox.org the instructions for putting the c150 into "Production Test" mode: insert the battery into the c150, simultaneously press and hold "volume down (left end of volume bar)" and "AB (the bottom portion of the ring-shaped button)", and then press and hold the "menu (power on)" button for two seconds. The display will then show "Production Test" and "MENU Key to Continuou" [sic]. Press the "menu (power on)" button, then you get to choose between "Test 1" and "Test 2", use the ring button to choose which one you want to run. You will need to connect the c150 to a computer using the USB cable for "Test 2" (it doesn't matter that the PC does not recognize the c150). My c150 passes both "Production Tests", but when powered on normally, it is still frozen stuck on the last track (see my post above).
The webpage for the c150 on rockbox.org also provides a link to another firmware update (v2.0.008A), which needs to be installed using "tcctool". I tried this, and was able to install the v2.0.008A firmware (apparently successfully, no error messages), but this firmware update does not fix the frozen track problem, and it also changes how Windows XP recognizes the c150. Windows XP now recognizes the c150 as a "libusb0" device and not as a "USB TCC77x" device as it did in the past. It seems that tcctool makes changes in the Windows registry which causes Windows to recognize the c150 differently. I haven't messed with the registry to try to restore the previous TCC77x device manager.
