and then "uncaught error I2C", which fills the screen

Ok, thanks - that's interesting. So that means that the Bangle can't communicate with the Touchscreen IC, so either the chip has locked up, or the physical connection to it has become disconnected.

It's pretty rare that happens, but in the past I'm pretty sure someone reported this several years back and power cycling the watch did fix it...

but can't scroll or touch anything so can'r access the flatten battery option.

Ahh, sorry - yes, of course. Please can you connect with the Web IDE and paste the following into the left-hand side, that should have the same effect:
```
      Bangle.setLCDTimeout(0);
      Bangle.setLCDPower(1);
      Bangle.setLCDBrightness(1);
      if (Bangle.setGPSPower) Bangle.setGPSPower(1,"flat");
      if (Bangle.setHRMPower) Bangle.setHRMPower(1,"flat");
      if (Bangle.setCompassPower) Bangle.setCompassPower(1,"flat");
      if (Bangle.setBarometerPower) Bangle.setBarometerPower(1,"flat");
      setInterval(function() {
        var i=1000;while (i--);
      }, 1);
```
