Hi - thanks for the video!
I'm sorry you'e had troubles with this pretty much out of the box. It sounds like you hit the issue @fanoush mentioned.
Basically if the storage had got corrupted somehow, the 2v15 firmware had some optimisations and those unfortunately didn't check for the corrupted data and caused it to hang when booting. I'll release a 2v16 firmware that has it fixed soon, but until then you can use a 'cutting edge' build that has the fix in (these have all the latest changes in).
Unfortunately because the watch is not booting into the Bangle.js firmware you can't use the firmware updater app to re-upload a new firmware, so instead you'll have to use the fallback method using an Android/iOS app - there are some instructions here:

Sorry again about this - and hope that helps!
