`reset();` in Web IDE gives error and makes Bangle.js 2 stuck

I'm trying to follow this tutorial: https://www.espruino.com/Bangle.js+Devel­opment

When I get to reset(); the Web IDE answers with following and Bangle.js 2 is stuck with screen which says just "Reloading...".

>reset();

Also Bangle.buzz(); doesn't seem to do anything and Bangle.beep(); makes watch vibrate.

Are all your apps up to date? That usually happens when the bootloader is seriously out of date.

Once you're sure they are all updated you can run load('bootupdate.js') in the IDE just in case to force an updatre of the .boot0 file that is giving you that error

How would I know that or update apps? I just updated firmware, is that enough?

ps. Also that tutorial doesn't say anything about needing to update apps.

ok, that was it (although Bangle.buzz(); still doesn't do anything after all is updated).

Ok, great. Is it possible you had Vibration set to off in settings?

No, and also it would be strange if that setting disables Bangle.buzz(); but not Bangle.beep();.
