Sansa Fuze+

<< < (91/162) > >>

pamaury:
Jean-Louis Biasini sent me his first Fuze+ which suffers from the same problem (internal memory is not writable anymore). I'm looking at the problem but I have no solution for now. I will add support for booting from the sdcard if the internal storage fails. That will not fix the broken ones but hopefully prevent total failures for the others. Has anyone of you tried to send it back to sandisk ?

luetzel:
No, I haven't sent it to sandisk. Meanwhile, I managed to see all partitions.
Looks actually exactly as in other posts that I've seen:

Disk /dev/sde: 15.9 GB, 15925772288 bytes
1 heads, 1 sectors/track, 31105024 cylinders, total 31105024 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Device Boot      Start         End      Blocks   Id  System
/dev/sde1   *      109568    31105023    15497728    1  FAT12
/dev/sde2            1024      101375       50176   53  OnTrack DM6 Aux3

 fdisk can remove/create them and write to the table, however, when trying to format it with "mkfs.vfat, /dev/sde1" it fails with an error.
Post Merge: April 22, 2012, 06:27:34 AMAh, I forgot to add that the OF starts, but shuts down because of a database error, requesting a reformat to fix it. The rockbox build installed is from 120417.

megal0maniac:
I'm sad to say that my Fuze+ is dead.
Plugged it into my computer (while off), had the bootloader "USB mode" screen.
When I unplugged it, the screen was very bright (more than the usual CRT effect)

Could only see half of the icons, if I went into a menu and back to the main menu, all the icons were gone until I went into another menu.
I went into settings, got a "Divide by zero" error and turned it off.
Now it won't turn on, regardless of what I try.

Have even opened it and de-soldered and reconnected the battery, but it won't do anything.
Battery was low at the time, but still had about 2 hours of play time.

RIP Fuze+...

pamaury:
Have you tried the recovery mode ?

megal0maniac:
Absolutely nothing is working.
Not recovery mode, no charging, nothing.
It's totally dead.

Got it into recovery mode... But now what?
Does this mean there's hope?
Can I dump a firmware image like this?

It seems as though the player can no longer locate the internal memory whatsoever.
A slightly more severe failure than most, but internal memory related once again.

I've been told that the only foreseeable method of recovery would be to modify the i2c eeprom to boot of a micro SD card, which wouldn't exactly be recovery as the internal memory would still be inaccessible, but would make the player usable once again by circumventing it completely.

The eeprom is write-protected, but this should theoretically be possible to change by pulling the write protect pin to GND.
Then it's a matter of knowing what to write and where to write it, I'd imagine.

Any credit for useful information goes to pamaury.
Just thought I'd post this for informative purposes.

Bottom line: My Fuze+ is essentially dead, without chance of recovery at this stage.
(It isn't possible to determine whether this is Rockbox related or not, but as it says on the wiki, you install Rockbox at your own risk.)
