Bangle.js 2 stuck in boot loop

Thanks Gordon - no idea how I missed that...

Unfortunately there is no way to take those steps. This is what happens while there is battery capacity (without touching the screen or button):

1. White bootloader appears (is this right term?)
   
2. Loading meter fills
   
3. Black Bangle.js OS screen appears
   
4. Checking storage...
   
5. Storage Ok.
   
6. Return to 1.
   
   

Is there any lower level way to reset it? Bit worried it's bricked.

EDIT
Quick thought - could there be some kind of contact inside the button which gives it pressed state constantly? I was fine until I took it off my wrist - no idea how that could have caused it, but perhaps an option?
