Instructions on Flashing a Daily Build

Daily builds are created from a manifest file, that contains commits from different parts of the stack. (gaia, gonk, and gecko). Our Engineering team has set up a daily repository for daily builds being built against specific devices.

Downloading a build

• The main builds are stored daily in the FTP directory. Note: These are proprietary and cannot be distributed.
  • For directory access, please see someone from the Mozilla QA team. (tchung@mozilla.com, jammink@mozilla.com)

Pre setup

• Mac/Linux: install Android SDK and tools
  • Add adb to your path (lives in /platform-tools)
• Windows: install Android SDK and tools
  • Add adb to your path (lives in /platform-tools)
  • install cygwin

• NOTE: Make sure the debug settings on the phone are turned on.
  • Example for Inari: Settings > Device Information > More Information > Developer
