PBZChucker
What it is
An (incomplete) Android app to install Pebble PBZ firmware files.
How it does it
Pretends to be a working companion app but then betrays the Pebble's trust and uploads firmware.
What it needs to be
A full lightweight firmware flasher that can be independent of any other apps.
Requirements
Build
I strongly suggest just using the pre-signed releases, but the app has no special requirements that don't come pre-installed with Android Studio
