Is your device completely unresponsive? Did all of the other troubleshooting and replacement guides not fix your problem? If so, there's a good chance your motherboard needs to be replaced. Follow this guide.

    Oui tuto bien clair. Opération réussi !

    Bien qu’adroit de mes mains, et après avoir découvert la “bête à coeur ouvert”, je ne sais pas si je me serais lancé... C’est tout l’interêt de ce Tuto qui invite à le faire (car pas trop de détails), et qui suivit pas à pas permet de s’en sortir. Bravo

    Merci Dan.S

    Ustedes reparan el gear s3 Frontier? El mío presenta una falla, algunas veces se ve la pantalla, otras veces solo muestra un error y se pone oscura, no sé si sea la placa o la pantalla la que de el error. Gracias

    Better replace the 2 bolts from next step first.

    • Note how the end of the ribbon cable seats in the plastic chassis. Look for the plastic pin on the chassis when re-seating.

    What happens if the battery ribbons breaks?

    Hi the ribbon has come away from the mother board. How do I stick it back on? What type of adhesive do I use?

    I also broke the ribbon for the motherboard. What adhesive should I use to reattach it

    danieljchoe - 返信

    Be very careful with a ribbon that cannot come off on the opposite side of the red box on the motherboard when preforming this step. I found this and managed to avoid it.

  8. Separate the battery from the motherboard. The battery and the motherboard are secured with adhesive; some force is needed.
    • Separate the battery from the motherboard.

    • The battery and the motherboard are secured with adhesive; some force is needed.

    • Lithium-ion batteries are potentially dangerous. Handle with extreme care and do not puncture the battery.

    I just used this guide to do a replacement, the watch works perfect now. Pay attention to whats in your hand vs whats on the guide a couple of the steps are not as straightforward just take your time. Overall good guide though.

    Replaced the battery successfully with this guide. Take your time to carefully see whats on the watch compared to the guide.

    I removed the battery ribbon cable in step 7 by using a really small flat screwdriver to lift the cable from the housing. It's attached with adhesive tape.

    Eric Mulder - 返信

    Perfect. I just remove the two bolts form step 6. Battery was a little difficult to remove due to a tape that attached it on board.

    Works very well.

    It took an extra tool that isn’t mentioned (very small, thin, straight screw driver), but it took only 20 minutes! Great step by step instructions!

  9. When reassembling, place the battery into the plastic assembly first. Don’t stick it to the adhesive first. This way, it’s easy to position the battery cable. When securing the battery cable, make sure the hole that the peg goes through is round. The hole on your replacement battery’s cable could be malformed. You may want to widen the hole before securing the cable.

    • To widen the hole, use the Pro Tech Toolkit’s SIM tool, a small paperclip or similar fine-tipped tool. The tool can also be used to gently press the battery cable into the correct position. Do this carefully to avoid damage.

    • Follow steps 8-1 in reverse order to reassmble.

Where can I purchase a motherboard for my Samsung Gears s3. Cant seem to find them

Need motherboard for samsung gears

Mel Swint - 返信

Hello I was in MRI and my watch was unresponsive. What is the problem?

Shaymaa - 返信

My button Ribbon on my Mainboard has come detached. It seams like there was some adhesive holding it on so i pressed it together. put it back together but the buttons wont turn the watch on. it is charged. I can’t tell if the Ribbon was soldered on or some adhesive used to make those connections. Any help would be appreciated.

Rollins Gamer - 返信

I have the have the same issue! I replaced my battery, accidentally removed the power flex ribbon (the one with the power buttons) i bought two replacements, tried both, my watch won’t turn on. It does charge still and the LCD works, just doesn’t turn on. :\

Sal - 返信

EDIT: Just after posting this comment 10m ago, I took another look at the watch. You need to make sure the power flex ribbon is FLUSHED on the connectors on the board. I used scotch tape to test this theory and my watch turned on no problem. Consider getting circuit board adhesive from your local tech store for a cleaner install.

Sal - 返信

I also detached my ribbon. What did you guys do to reattach it?

danielhaugland13 - 返信

I found this : https://www.aliexpress.com/item/33051329...

But what about the software? will it be installed in the board? If i buy a mainboard from aliexpress will samsung allow me to update it?
