Hi,

my bangle.js 2 has a bootloop after an firmeware update and I can't get in the recovery mode. I'm getting:

Watchdog
BL 2V20

Check Storage
no new FW

booting

I try to get in the recovery mode as described in the tutorial, but it do not work. When I hold the button, the bangle boots like described above.

Hi,

It looks like the standard firmware update mechanism has failed in your case. You'll just need to go back to the fallback mechanism I'm afraid. The easiest method is to install an app called 'DFU' on your phone.

(ignore the bit at the start about it suggesting you use App Loader, as that won't work now)
