I have the same problem with one of my daughters sansa mp3 players (m240 firmware V4.0.44A). I purchased it in Dec 06 and it began freezing In Jan 08 1 month after the warranty was up.
I have tried all options on resetting this unit and it appears to be unrepairable. Really such a shame, I am very happy with the other sandisk mp3 players i have purchased for my other children (differnt model #'s as well as different firmware versions)
This unit was used very little and taken very good care of. It certainly didnt begin to freeze up on the startup screen because of use but because of the defective firmware vesion.
I guess my point is there are probably alot of people who just went out and purchased a new one, or didnt take the time to mess with support or get their unit rma’d- because they were not aware that the problem was from a defective firmware version , but an actual defective unit. Even if it freezes after warranty,most of these units would all still be ok if they had a functional firmware to begin with. I’ve always taught my kids to take care of their things and they will last much longer. that just is not the case with a defective product. I think any 200 series players with this specific bios version and this specific problem should be recalled, replaced regardless of date of purchase. Some people can afford to buy a new one every year, I however cannot. I wouldn’t normally expect something to be replaced after warranty - only if it was a defective product. Only if my daughter would have used it more often it would have probably began freezing within warranty.
I sent them an email today. If they take care of me I’ll gladly continue to purchase their products in the future.
