    Same here, its impossible to get the screws off. They’re almost stripped now too.

    Sorry to hear that. Here are some tips on how to get those screws off hopefully: How to Remove a Stripped Screw

    Just started working on watch. Can not get the screws out. I purchased the recommended tools. Screws won't budge. I have not stripped them yet. How do I get them to loosen up?

    Same here. I did buy your Electronics repair Bundle. The Y000 is too pointy, we need a flatter tool

    Hi Ladies & Gentleman, please try as follows:

    Use a spray can of "WD 40" with a spray pipe/tube but DO NOT spray into the screw holes. Just spray shortly on a piece of paper, a drop of WD40 will remain at the end of the spray pipe. This drop I put into the screw hole position. Do this for each screw hole and leave the stuff approx. 10 minutes alone. Afterwards use the screw driver as normal to turn the screws out.

    *** After the drop is placed into the hole do not wait too long as WD40 is crawling into "even not existing gaps"

    *** just use a small drop of WD40.

    *** I intend for using 4 new screws as the head (Tri-Pont profile) seems worn out. But if I get new screws for sure I will go for a TORX profile because its the best as you don't need to apply axial force on screw driver.

    Very best regards from Harald (a German machine building engineer)

    Harald again to Robertob67:

    It is NOT the Tool Y000 but the Y00

    • Use an opening tool to get between the back cover and the metal housing of the watch.

    • Carefully pry the plastic back cover open.

    • Don't remove the back cover yet. There is a flex cable running to the core assembly inside.

    You may need to use a small screwdriver or letter opener to pry the case apart. I found with two different spudgers I could not get it to budge.

    • Lay down the watch and lift the back cover to access the sensor connector on the motherboard.

  4. Opening the Galaxy Watch: step 4, image 1 of 2 Opening the Galaxy Watch: step 4, image 2 of 2
    • Use a spudger to disconnect the sensor flex cable from the motherboard.

    My 2019 Gear Sport has no flex cable it used a post where the flex cable is. This plugs into the mother board.

    Much better for disassembly.

    • Remove the back cover.

    • When closing the watch make sure the rubber gasket is undamaged or replace it with a new one.

    Has anyone seen a listing for the gasket?

    anyone where can find the rubber gasket?

    Melvyn Chang - Reply

    is the gasket the Adhesive? If not, what adhesive suggested and how do you apply it?

    batato kr - Reply

    No, the gasket is not the adhesive. As adhesive you can use this under the battery.

    woher bekomme ich eine neue gummidichtung?

    Anja Müller-Dreßler - Reply

    Hat jemand eine Quelle für die Dichtung der Rückabdeckung (rote Dichtung, 3. Bild Schritt 5). Hat jemand versucht die erfolgreich selber herzustellen?

    Helge Korz - Reply

    Falls jemand die Gummidichtung im Netz findet, gerne hier posten. Wir konnten bisher noch keine finden. Selbst hat es nicht, und die haben recht viel für (Samsung) Smartwatches.

    Tobias Isakeit -

    Same question : has anybody found a solution for the rubber gasket ? I am not confident at all in the waterproofing of the watch now ...
