How to disassemble your S1mp3
By disasembling your s1mp3, you may identify the board ID of your s1mp3 and identify your s1mp3 with this information. As there are many different S1mp3s, there are also many different ways to open them, and there is no way to cover all on this guide. If your s1mp3 looks like the standard s1mp3 type, skip to the How to disassemble a standard s1mp3(link) section.

Look for screws
First, examine the exterior of your s1mp3 case and look for screws. If there are no screw on the exterior of the case, take another look. A plastic cover may be hiding a screw. Some s1mp3s can be quite tricky to disassemble. When/if you find screws, take the appropriate screwdriver (probably there will be small screws, and you will need an equally small screwdriver) and remove them.
Look for gaps
If the s1mp3 did not dismantle automatically after you remove the screws, or if your s1mp3 does not have screws, you should try to force your s1mp3 to open, in some gap, using a screwdriver. Note that this may break your plastic case, so take care and be very gentle with the case, DO NOT force it too much. And be sure there is NO SCREW before trying this. If you aren't sure on how to open your s1mp3, it's best to take some time to think and ask help from a friend.
Remove the internal screws
Probably there will be screws in the internal part of your s1mp3. Remove them. After this, your should be free to explore all over the s1mp3 hardware.
Explore your hadware
This is the first bit of information you should seek in your s1mp3. The Board ID code is the only trustworthy identification of the device.
The code is written in white on the green board. It's located usually behind a plastic sticker, near the minus battery pole. If you are having problems to find your board ID, it may be behind the LCD cable. You might have to lift it carefully to see the bard ID. Seek everywhere! Both sides of all the boards! Some people take a bit of time to find the small white words. We qualify anything printed in white on the green printboard as the board ID.
MP-482C MAIN V8
The ATJ20xx chip is the "processor" of the s1mp3. There are some variations, such as ATJ2085, ATJ2087, ATJ2051, AMP2051, AMP2085, and others.
NAND memory chip
This is the chip with holds the physical memory of your s1mp3. The chip number of your s1mp3 is a useful information when having Temp:Memory_problems.
FM radio chip
This is the FM radio receiver of the S1mp3. Usually, it's a Philips chip. If this chip is not present on your S1mp3, it means that your device will not support the FM radio feature.
How to disassemble a standard s1mp3
(Written by Crunchy )
- 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
- 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.
- Separate the bottom plastic from 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.
- 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!
- 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.
- 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. Extra attention to see if the buttons are well fit on the case, for not to force then while closing the case.
Now you have an open player, just seek everywhere on your player's PCB for small-written letters. Anything written in white on the green board qualifies as a board ID. Some people take some time to find the small white boardID info, but it's present in MOST of the s1mp3's out there.
