The plan was codenamed "BBX": Chan hoped to raise $6 billion, and then approach BlackBerry with this takeover plan, outlined in a PowerPoint deck on the following pages.
BBX — which we noticed when it was mentioned on The Verge — would have replaced BlackBerry's management, and ditched the phone's operating system. In its place, Chan would have the company use an Android "fork," meaning a version of Android with some of BlackBerry's own tweaks and styling on top.
The plan didn't get enough backing and came to nothing.
Here's how Chan and his team envisioned the takeover of BlackBerry. You can download the deck in its entirety from Slideshare.
