How do I update Firefox OS?


I have a ZTE Open Firefox OS device. It is currently running build 20130723181018, which according to the Git commit information is over a month out of date. However, the device says that I'm on the nightly update channel: how do I get the nightly build onto my device?

Additional System Details


  • User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:23.0) Gecko/20100101 Firefox/23.0

That seems to have updated the apps, but has not updated the core OS. On update, it remains at the month-old version, and not the latest build (that presumably was generated yesterday).

I have this problem on the same phone with the same build. When I check for an update it just says "Checking for update..." and then nothing. No output what so ever, not even "No update available".

I do get a pop up at the bottom saying there was an error downloading updates.

  1. Is there a way to manually update the OS?
  2. How can I enable logging so that I can see the error when trying to update the OS?

Firefox OS updates can only be pushed out by the device maker. Much like Android and other mobile operating systems, the device manufacturer must compile the OS in order for the firmware update process to work.

Alternatively, you can compile Firefox OS and flash it to your device, but this is unsupported and only recommended for advanced users. While ZTE has not confirmed it yet, it is very likely Firefox OS 1.1 will be made available by ZTE in the coming weeks/months.

It is 14th of December 2013 and no update from ZTE.

Would compiling of an entire operating system be a viable option for a person who has never compiled anything from source codes in his entire life?

Thanks for making an effort in resolving the issue I was having. I realize that I have some learning to do with the netiquette of mozilla support.
