Videos: getting started with your Flame device

Flame reference deviceThe Flame Developer reference phone is currently on its way to developers who either are Mozillians, bought them or have created apps for it.

You can buy the flame device online at everbuying, for $170 including postage and packing and world-wide delivery. There is no contract and not obligation to a mobile provider. This is a developer phone to be used with any SIM you have at hand.

Today we’re going to show you in four short videos what the Flame device is, how to set up your Flame device as a developer phone once you have it, how to flash a new Firefox OS image onto the device and how to throttle the RAM to simulate slower devices.

For all of this you need a few things:

  • A USB cable to connect the Flame device
  • You need ADB and Fastboot installed. You can get this by installing the full Android developer suite or using these small and simple installer for Windows or Linux and OSX

Say “hello” to the Flame device

In this video we quickly introduce you to the Flame Developer reference phone, explaining its features and specifications.

Setting up your Flame device

In this video you will learn how to set up your Flame device as a developer device. This includes enabling the developer menu and getting detailed information about the running apps using the Developer HUD. This tool tells you not only the detailed memory consumption of your apps, but also the frames per second they run on and where you memory went. All of which directly on the device itself.

Changing the RAM of your Flame device

Out of the box the Flame device comes with 1GB of RAM which is a good number for a daily use phone, but much more than a lot of the commercially available Firefox OS devices have. That’s why we made it easy for developers to simulate less powerful devices by throttling the RAM using ADB and Fastboot.

Flashing a new Firefox OS image to your Flame device

In most cases, the over the air OS upgrades of Firefox OS should be enough for developers to stay up to date. If you want to live closer to the edge though, you can easily flash images provided by Mozilla to your device. All it needs is rebooting your device from the command line and running a shell script.

That’s it for now – stay up-to-date on the Wiki

We hope these videos have shown you how much insight into your apps and Firefox OS you get on a Flame device. All the information is also available on the Flame Device wiki page and will get updates as new information is available.

    It would be nice to have something like clockworkmod right from the box.

      What do you mean by Clockworkmod? This *is* the free version of the system. No manufacturers blobs anywhere… (except for kernel drivers, but these just unavoidable pain). What is missing in terms of opennes? You can build whole system (which is identical to the one provided by Mozilla) from sources (

        Clockworkmod = CWM, the modded recovery mode on Andoid phones.
        You boot into the recovery menu, select a file and install it on your device. No flash scripts are be required for that, just the files on phones internal memory or sd card.

        The Flame has a recovery menu, but there are no files out there to update the flame through it.

        Also there is no “native way” for Windows users to flash their Flame device to a nightly build (1.4, 2.0, 2.1). The available script is only for Linux and MacOSX.

        Of course Windows users could setup e.g. Ubuntu in a VM and flash the device through it, but thats not the ideal solution in my opinion.

    See MDN for detailed instructions on how to flash your device with a newer pre-release version of Firefox OS.

    Tip: Flash one of the production builds if you want to get daily OTA updates.

    Thanks for the videos. My developer menu looks completely different. For one, I don’t have a Developer HUD. OS version is 1.3 pre-release. Is that the issue?

      Yes, the OS showed in the video is a later version.
