| ====Notes About Terminology====
| | This page [https://wiki.mozilla.org/FirefoxOS/TCP/Flashing_your_device/ has moved]. |
| * Firefox OS is frequently referred to by its code name (and original name) ''B2G''.
| |
| * The files we use to flash the device are referred to as images, [http://en.wikipedia.org/wiki/Read-only_memory ROMs] or builds.
| |
| * The proper abbreviation for Firefox OS is ''FxOS''.
| |
| * The process of [http://en.wikipedia.org/wiki/Flashing_%28technology%29 ''flashing''] refers to writing the ROMs to the device to update the operating system to a different version.
| |
| * ''Flatfish'' is the code name we use to refer to the 10" tablets being tested.
| |
| ==Flashing Your Device==
| |
| <div class="note error">'''Mac users:''' It is currently not possible to flash Firefox OS builds to Flatfish from a Mac. We are working to remedy this.</div>
| |
| Before beginning, it is best if your device is not almost dead (if the battery's red, it's almost dead).
| |
| * Download [https://www.dropbox.com/sh/b2py1btcwstqldl/AABblbq_csa1IHQwdvLdfptTa a recent build] you would like to flash.
| |
| ** Tip: Using the ''Download'' (as zip) option will save time and make for a much smaller download. [[File:dropbox_download_button.png]]
| |
| ** Check the [https://etherpad.mozilla.org/CmJbD8V0QX build status] page to see if there are notes about major issues with the listed builds.
| |
| ** If none of the listed builds are viable ("good"), download the build in the stable folder.
| |
| * Turn on your device and plug it in to your computer via the USB cord.
| |
| * ''Linux users'': If you have not, you need to [https://developer.mozilla.org/en-US/Firefox_OS/Firefox_OS_build_prerequisites#For_Linux.3A_configure_the_udev_rule_for_your_phone add udev rules] for the device (use idVendor '''18d1''' and '''0bb4''' - that's ''two'' separate rules).
| |
| * Extract the zip file you downloaded into a folder and run the ''flash'' file.
| |
| ** On Windows the file will be called '''flash''' or '''flash.bat''' (if you have file extensions unhidden). The icon may have gears in it.
| |
| ** On Linux the file will be called '''flash.sh'''
| |
| ** On Mac the file will be called '''flash_mac.sh'''
| |
| * You should then be asked if you want to flash user data. Saying yes will clear any user data such as apps you have installed and emails. Some data, such as that stored on an SD Card will survive. <br>If you are moving between a major version of FxOS (e.g. 1.4 -> 2.0 or 2.0 -> 1.4) we recommend that you choose to flash the user data (thereby deleting it).
| |
| * ''Windows users'': If the tablet is plugged in to your PC but you see <code>error: device not found</code> then you probably need to [https://developer.android.com/tools/extras/oem-usb.html install the OEM USB drivers] for your computer.
| |
| * After making your userdata selection the tablet will reboot into "fastboot" mode and display the Firefox OS logo. In the command window, if you see <code>< waiting for device ></code> for longer than 30 seconds, try unplugging the USB cord from your computer and plugging it back in.
| |
| * The flash will take a couple of minutes and the screen may display random colors. Do not unplug, disturb or mock the device during this time.
| |
| * Once finished, press any key to reboot.

| A technical note: Our current packaged zip does not include ''boot.img'' (aka gonk) or ''recovery.img''.
