If you have tried to upgrade your player with the wrong firmware and you find it no longer turns on or is not recognised by your computer this guide may help you to restore your player. I suggest you read the whole guide before starting so that you understand what you are about to do and have everything you need. It is not fool proof there are no guarantees. If you have backed up your players firmware you have a much greater chance of succeeding if not then you will have to search for a firmware version that is compatible with your player. Look for versions that have the same features as yours and similar layouts and menu pictures. If you know the version number then look for that version. If you do not then get a few versions
First arrange a space near your PC where you can work. Make sure that your player is switched off and disconnected from your PC. You will need a fine screwdriver and a pair of metal tweezers. If you do not have any tweezers a second fine screwdriver or a bent paperclip even will do. I suggest that those without a firmware backup download a selection before starting.
Remove the 4 screws 2 on either side of your player.
Gently remove the stainless steel backing taking care not to lose the switch from the top of the player
Now connect your player to your PC and turn it on.
Using the tweezers or other metal item gently make a connection between the pins on one side of the chip. I have found this can be quite random you may also have to do it a few times.
Your PC should now detect your player as a ADFU Server and install the drivers. If this happened you can skip the next section and continue after the red text.
If your player is detected as a USB device then you will have to follow the next steps in Red. Windows will try to install a driver for your USB device and fail. Right click on My Computer icon and select properties, then go to the Hardware tab and select device manger. Here you will find your USB Device.
Right click on the device and select properties. When the properties dialogue opens select update driver
Then select “Install from a specific location” and “Don’t search. I will choose a driver to install” then press next.
When the next window opens choose “Show All Devices” then next. In the next window select “Have Disk” then “Browse”. Now you will see you are looking for AdufUpdate.inf which you will find in the Windows Folder.
Once selected you will be asked to select the driver and it will be installed
Now the player is in a state where you can upload firmware so open the MP3 Upgrade Tool and you will be presented with this dialogue.
