BangleJS 1, cannot install default apps after firmware update.

I have an old BangleJS 1 that I am trying to use again. I installed the latest firmware 2v15 and tried to installed the default apps.

It is happy having the time set, refreshing the installed app list (none) but it seem to be timing out installing the first default app (bootloader).

From the browser console...

I have also tried ti with 2v10 and 2v14 (same problem installing the apps).

Any ideas?
