whole problem description:

SOLUTION:
The problem was that the second NAND flash chip contained wrong data.
But I found the way how to erase both chips and load the firmware to the clean memory.

The chip can be erased by special SCSI command.
1.) Get the SCSI Utility from http://logix4u.net/.
2.) Connect the player to PC and initiate the Recovery Mode with updater.sb that works (in my case it was 1GB firmware v006.003.260)
3.) Run the SCSI Utility and press F5 to refresh list of connected devices
4.) Right-click on the player in the list and choose "Execute Custom CDB"
5.) Then fill the table with these values:
Code:
BYTE 0: c0 
BYTE 1: 7 
BYTE 2: 0 
BYTE 3: 0 
BYTE 4: 0 
BYTE 5: 0
Other cells leave blank, so the CDB Size will be 6.
(Values are in the hexadecimal form.)
6.) Then press Execute, accept the warning and wait a moment (10 sec.).

Now the first chip is clean.
The problem is that when you have 2 chips.
You must do a "reconnection" in order to access the second chip. But don't worry, it isn't so hard as it sounds. :wink:
1.) You must disassemble the player
2.) Check the NAND chip (there is only one physical flash chip, but it consists of 2 separate logical chips)
3.) Google the datasheet for you memory chip.
4.) Now you must short-cut (make a connection) the CE1 (Chip Enable 1) pin to Vcc=3.3V (if it is the specific voltage for 'logical one') to disable the first chip.
5.) Short-cut the CE2 (Chip Enable 2) pin to Vss=0V (GND) to enable the second chip.
6.) Do the erase process with the SCSI Utility again, now with the second chip.
7.) Remove the wires (the shortage).

Now you can boot (initiate Recovery Mode) with the 2GB uploader.sb and flash the 2GB firmware (select the Format Data Area in the flasher utility).

This is how I did it. Now I have whole 2GB of capacity back.
Maybe it should be enough to erase only the first chip. I have erased both and it works.

Example NAND flash datasheet:
http://www.datalabs.ru/files/HY27UH08AG(5_D)(Rev0.6).pdf

Complete list of SCSI commands:
Code:
 
byte 0: 
SCSI_OPCODE_SIGMATEL_READ_COMMAND  0xc0 
SCSI_OPCODE_SIGMATEL_WRITE_COMMAND 0xc1 
 
byte 1: 
GET_PROTOCOL_VERSION        0x00 
GET_STATUS                  0x01 
GET_LOGICAL_MEDIA_INFO      0x02 
GET_LOGICAL_MEDIA_NUM       0x03 
GET_ALLOCATION_TABLE        0x05 
ALLOCATE_MEDIA              0x06 
ERASE_LOGICAL_MEDIA         0x07 
GET_LOGICAL_DRIVE_INFO      0x12 
READ_LOGICAL_DRIVE_SECTOR   0x13 
SET_LOGICAL_DRIVE_INFO      0x20 
WRITE_LOGICAL_DRIVE_SECTOR  0x23 
ERASE_LOGICAL_DRIVE         0x2f 
GET_CHIP_ID                 0x30 
CHIP_RESET                  0x31
If you have any questions, please ask. If you really want I can take some photos of the process.

Hello.
I have a SigmaTel MSCN Lavod Mp4 player
Its is 1 cm thin. black, has a 4/3 screen, a round pad with really odd simbols.

The problem is that the memory (2GB) can not be found anymore. not by the player itself nor by the PC.

These firmware tricks are cool and all. but how can you apply them when you can't go into the directories needed?

Thanks for the guide...

I have a mp4 watch 2gb like this...

MP4 Watch Link

I desperately need the firmware for this watch, as mine is dead, it recognizes as flash disk and when I put it in recovery mode it shows STMP3500 (I believe this is the chip in this watch)

If anyone has this watch can you please extract the firmware and send it to me?
