Internal flash failure in Sansa Clip +

[maxerist]

Hi,

My Sansa Clip Plus turned into semi-usable state. The symptoms are
- The boot loader freezes at logo or checksum screens most of the times, only rarely (1 out 20) getting into the rockbox player.
- The internal disk when accessed from one PC shows the structure and info very slowly after about 10 minutes of background work. Another PC doesn't see even this (the letter is here, but no size information, no file browsing).
- The Sansa original firmware started successfully (on Home-Power) until recently. Now it complains it has no space for Music DB. If I press the central button during this, I will get into original player, otherwise, it will power off. I didn't update SD card contents after this symptom started to appear, I suspect the "Refreshing your media" will probably introduce some new surprise to me.

I suspect that internal flash memory became invalid or something. But what choices do I have? If I try to re-install Rockbox, I will probably fail since the main RockBox OS files are installed in the internal memory  which became unusable (CMIIW). If it would be possible to load them from the SD card, I could install Rockbox at SD, but I don't know whether it's possible or not.

Any help will be appreciated,

Thanks,

Max

I don't think anyone has made a bootloader that could load from the SD card.  Its probably possible to develop one, but to even flash it you'd have to have the OF working reliably enough to do a firmware update.

The low chances of installing to the SD card led to new attempts to overcome the problem. Finally I managed to format the internal drive from the original firmware and install Rockbox with Rockbox utility without installing the bootloader. Currently everything works fine.
