So… let me tell you my story of fixing this.
Short story: Soldering the wire works for me too.
When you first take the watch apart you have to use a significant amount of force,
to pull out the black plastic frame from the steel frame.
Then you realize how small those tiny little contacts are. On the photos attached here
they seem like they are big, but they aren’t
So I immediately decided to go with the toothpick method because how small those thing are.
Let me tell you: DON’T EVER use the toothpick method. I managed to broke off the topmost
smd (closest to the back cover) next to the down button. Surprisingly the watch was still working
after this. (at least it seemed to).
So after this I had to go back to the soldering method. You will need steady hands and at least some
magnifying glass or very sharp eyes.
After soldering finished, I put everything back together just to realize that the backlight and the charging led
light are stopped working. So now I have working buttons and broken led lights.
Also… I had to take off the back cover several times now, because the contacts are randomly not contacting
sometimes causing the charging not working at all or all of the buttons not working. These are resolved by slightly moving the
whole frame a bit or putting some soft material on top of where the pcb has the contacts with the board itself.
But I could not manage to make the backlight and charging light work again. Anyone have some ideas what could cause this?
I mean yeah, I broke off that smd, but it seemed
that all of the buttons have 3 smds next to it, so I’m thinking it is only for the buttons and the
buttons are working now. Am I wrong here?
