according to “Battery is soldered to the mainboard. Maybe i have to wait until it went flat.”, it may be the problem of battery. A new battery is needed.
@Vmax it is more likely either a screen issue that we have seen before or the OS has got stuffed.
The battery can be disconnected from the board - this is what you should try first. Just pull the flat board plug under the back cover and then re-connect after 30 seconds. Also try the “hold the side button in until the watch vibrates” operation. That will wipe the cache and re-boot it.
And if you go over to the firmware support section for these watches there is a photo of the main board . The flat connector at the bottom of the photo is the battery connector.
Well, that is very odd. My battery is not soldered. It has the flat silver topped connector you can see in the photo I mentioned earlier. I have even removed it from my old I2 as a spare…
Did you cleave watch to cradle first then connect them by USB to power? as the back case is metal part, the charging operation should be conducted step by step. otherwise it will cause short circuit very easily, which will damage the screen.
@Vmax oh damn !! This happened to me too though. If you go to device manager and go to update driver and select the previous mtp driver - it worked for me .
Worth a try…
