Device Read/Write Problems

This page describes errors that might happen using the "MP3 Player Update Tool"(see Software tools), and delivers possible solutions:

Device Write Protected

In some cases this issue can be resolved by flipping the hold switch. It's similar to the write-protect tab on a floppy disk.

In simplier cases the switch may have become inadvertantly moved to the lock position - or - sometimes flashing a different firmware file can cause the hold switch to become reversed in its operation and so setting it in the locked position actually unlocks the device.

In cases where the device remains write-protected regardless of the position of the hold switch, this is a more serious problem, you will need to put your device into recovery (ADFU) mode as described in the Dead Recovery Guide in order to be able to flash a good copy of the correct firmware file.

Device Not Detected

If you get this error when you try to run software tools such as the formatting tool or the firmware update tool, it is possible that the software tool is not compatible with the device and trying a different version of the tool (if available) can sometimes resolve the issue.


Alternatively, the device driver/s may be suspect - check the device status (see USB modes) in Device Manager (Windows). Sometimes simply rebooting your computer can re-initialize the drivers and allow the device to communicate. Temporary conflicts with other software/hardware can also sometimes be leared with a re-boot of the host computer. You should also disable anti-virus and other services running on Windows as a last option.


It is also possible at this point that the hardware in the device has itself developed a fault. The USB ports on your computer can be eliminated as a cause of the communication failure by plugging other devices in to test them. If you normally use a USB extension lead then the lead should also be eliminated as a cause of the communication break-down. Plug straight into a port without a lead.

Unknown Flash Type

If you get this error when you try to run a software tool such as the formatting tool or the firmware update tool - It is possible that the software tool is not compatible with the device and trying a different version of the tool (if available) can sometimes resolve the issue.

It can also mean that your NAND flash memory is physically damaged, or the solder on the s1mp3 is bad, not allowing code to be rewritten. This is a unusual event, but it might heappen.
