Remove the four 4.2mm screws with a Y00 screwdriver.
Did you use iFixit tools? I just checked and I believe Y00 is correct. Y0 slips too easily. My test was with the Y bits from the Pro Tech Toolkit.
I too had to use an Y0 screwdriver (from Ifixit 64 bit driver kit....). Y00 just don't grip, may be some batches of the watch used different screws??
One screw just doesn't want to move, any suggestions/tips how to remove it?
Problem solved: after 2 times of careful WD40 application and blunting the Y00 a bit it came of with a lot of patience.
I also had a problem with one of the screws and flipping to Y0 worked for that one.
Yo use Y 0.6 y anduvo perfecto!!

Wedge the metal spudger in between the back cover and the frame along the seam.
-
Use force to pry the back cover away from the main watch frame.
Il est plus facile et moins domageable pour le joint de commencer par ouvrir le cache de connexion situé à coté de l’axe du bracelet long. On peut alors glisser la broche sans détériorer le joint, qui est plus éloigné du bord à cet endroit.
I’m pretty sure the seal is equally far away from the edge on all sides.
This was the hardest part. I did use thin flat head screw to dismantle it. Using the metal spudger felt like impossible due to its thickness.
Did using the screwdriver damage the case in any way? I’d recommend being careful using a tool with smaller surface area as that will apply more pressure at the point of entry. As the guide states, a Jimmy may also be used instead of the spudger.
Not sure if it's a gasket or some sort of sealant paste/gel. Just took my case off, and the gasket seems intact (fused to back cover of the watch. Quick search for waterproof sealant yielded lots of possibilities - don't know which one to choose. Can anyone with experience provide advice?
most things I have seen online say use an RTV like permatex black sealant. pretty available at like autozone or o'reilly or walmart.
Ma questa guarnizione impermeabile si puo sostituire ? Come controllare se si è danneggiata? Come evitare che entri acqua dopo averlo aperto ?
Il est préférable d'utiliser, si possible, un outil adapté pour l'ouverture des boîtes de montre.
Avec précaution, le joint n'est pas trop abîmé. Il est distendu. Possibilité de le couper et de le réajuster correctement.
I have used a the Jimmy and I didn't need to do any force at all
Que puedo usar para poner en la tapa y cambias el sellado ya que se me arruinó.
Quiero que vuelva a ser hermético.
Gracias

Detach the three connectors on the motherboard using your fingernail.

Separate the motherboard and front screen assembly using a spudger.
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
Better replace the 2 bolts from next step first.
The guide has you remove the screws second because it makes it possible to remove the whole assembly without snapping any cables.
Ok... Woher bekomme ich die Displayeinheit ???🤷🏻♂️

Disconnect the battery ribbon cable from bracket.

Separate the chassis from the motherboard.
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 broke my ribbon :( ordering a new one. How do I stick it on?
I also broke the ribbon for the motherboard. What adhesive should I use to reattach it
I'd like to know too please
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.
You should first detach/separate the buttons ribbon cable from the side of the plastic casing so you don't tear/break it accidentally. (orange box, the cable is soldered onto the motherboard cannot detach it from there)

Separate the battery from the motherboard.
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.
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.

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.

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.
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.
I also detached my ribbon. What did you guys do to reattach it?
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?
quisiera saber si cambiando la placa madre se puede acceder ya que tiene una cuenta y no me deja restablecer de fábrica se restablece pero vuelve a aparecer todo de nuevo
Pixels are on the screen and nothing else wen I turn it on
