I've got a firefox os flame phone. I installed the version 2.2 following this guide https://developer.mozilla.org/en-US/Firefox_OS/Phone_guide/Flame/Updating_your_Flame four days ago. Now I'm trying to change the update channel to the nightly, I followed the guide on the same website, everything seems to went smooth but after my phone rebooted nothing has changed. It seems that I did everything right but it doesn't work. Any help would be appreciated. Thanksv
You are able to change the update channel inside the developer menu. Please scroll down there to the end. The is the update channel, at my phone "nightly-b2g37" for Firefox OS 2.2 and the URL of the update server.
