1. Identifique el reproductor: Descubra el número de placaback to top

To know with Firmware file will work on your player, you must get the board number. It's the only safe way to identify your player.

Once you've found your board number, you may see if there is any tested firmware for your player at the Firmware list.

0) find a clear table / desk to work on, make sure the floor is not to messy. It'll be a LOT easier to find back those tiny little screws / plastic buttons that tend to fall out exactly the wrong way

1) stick a screwdriver/knife/needle between the USB plug and the bottom plastic part (the one that holds the battery) . Any gap large enough to fit a sharp edge in will do.

2) lever the bottom plastic of the rest of the player. It's not welded or glued tight, so it'll come of easily. Be forceful, but gentle, if necessary. Don't worry if you hear plastic "snapping" it's just the clips coming loose, you are not breaking anything.

3) in the four corners of the PCB (the printboard with all the chips) you'll find four screws, find a screwdriver that fits, and unscrew them PUT THE SCREWS IN A CONTAINER! Anything will do, from an egg holder to tupperware to an ashtray, JUST DON'T LOOSE THE SCREWS!!!! You can now lift off the main PCB. Be carefull, as the LCD connector cable (brown flat cable) is quite fragile. Don't break it!

4) You can now safely remove the chrome/silver/shiny ring from the player. Note how it fits UNDER the main PCB, and how the LCD connector cable goes through it. This bit is a bit tricky to reassemble later, so if you remember how everything was in the first place, It'll be easier to put it back together.

5) you can now see the back of the LCD board. there should be two screws in it. Again, take your screwdriver and unscrew them. Put these screws in a (different) container! Again, Don't lose the screws! you NEED them. Put them in a different container to make sure you don't mix them up with the four "main PCB screws", as that will cause trouble when you put the player back together. After all that, you can take the LCD board from the front of the case. Remember, the brown LCD connector cable is FRAGILE, don't break it!

Congratulations, you have now disassembled your S1MP3 player! To reassemble it, just follow this guide in reverse order.

well, I hope this little guide is of help to you, anyway, report back the results, even if it fails, even if it succeeds, and why it worked/failed. It'll be education for all of us.

3. Instale los drivers y haga que Windows detecte el reproductorback to top

First, uninstall the "mp3 player tools" you have installed previously. Install the 1.45 version available at the Aplicaciones y Utilidades.

Unplug the player and remove all the drivers related to USB at the device manager

Now, click "SCAN FOR HARDWARE CHANGES" button. Finally after the new USB drivers are installed, plug in your player.

If you have problems with drivers, they may be obtained at the place you've installed the MP3 player utilities(program files/MP3 Player Utilities/) At folders "Windows98Drv", and "Dissipate/drivers".

If you follow all this steps and windows still can't recognize it, you may try to push ALL the buttons while connecting it to the USB hub. Try every button, and keep the button hold. You may also try to plug it on another computer.

If nothing works, don't get desperate, you can still try to short-circuit the memory chip to make it run the "recovery mode".

4. Instale un programa de actualización compatibleback to top

Skip this step if the updater program runs on your machine.

Firstly, make sure you have done the previous steps, and disable any anti virus/anti spywares.

Try to plug your device with and without the batteries, and see if holding the buttons solves the update program start errors.

If you are still getting errors like "UNKNOW FLASH TYPE ", "FLASH NOT RESPONDING", "DEVICE NOT DETECTED", "DEVICE IS BUSY", You should uninstall you current updater program and try other ones. (see the Herramienta de actualización del reproductor)

If you still can't make it work, you can try to short-circuit the memory chip to make it run the "recovery mode".

5. Ponga el aparato en modo de recuperacion (cortocircuito)back to top

You must disassemble your mp3 player. If you haven't done this yet, check the disassemble the s1mp3.

Recognize the memory chip, near the ATJ2085 chip. It's usually a samsung chip, and it's the biggest silicon on the board. To help identifying the device components, check the Vista interna del s1Mp3. We have seen players with 2 memory chips, too. If you have one of those, you have to short the memory chip near the ATJ2085.

Now, without the batteries , with a flat screwdriver, touch any of the 8 IO legs of the memory chip. Then, with the screwdriver on, connect the player to the USB.

If you are successful, windows will recognize an ADFU server device. Now, let windows install the drivers. Now you may flash any firmware to the player, after finding a compatible update program.

You may need to do this process lots of time before getting a successful short.

6. Encuentre el firmware para su reproductor de mp3back to top

With your board number in hand, check the Firmware list . If you find a firmware compatible with your board, your 're lucky, try it.

But, if you don't find your board there, them you will have to find it yourself, by attempt and error. We unhappily CAN'T help you hunting. (Google can.)

All the firmwares we have collected so far are on the forum, get them and start trying. Post your complete experiences on the forum, so, with some time, we will catalogue all the FW files.

If you have a friend with a identical player it's easy, just ask him to extract the bin file from his player using La aplicación de Wire.
