Bangle firmware 2.10->2.19 update problem

Glad you got it sorted in the end, but the watch DFU screen says:

RELEASE BTN1 FOR DFU
BTN1 TO BOOT
BTN1 + BTN2 TURN OFF

The bootloader text is small I know, and isn't super helpful, but it's trying to say the same as the webpage:

• RELEASE BTN1 FOR DFU - release BTN1 to enter DFU mode
  
• BTN1 TO BOOT - keep holding BTN1 to boot into Bangle.js
  
• BTN1 + BTN2 TURN OFF - (keep) holding both buttons to turn off
  
  

I just tried again here and it works exactly like that, BTN1 (top right) is what you need to enter DFU, and BTN2 (middle) has no effect - you can enter DFU by releasing BTN1 when ==== goes across the screen even while holding BTN2
