I was looking for an update for the past few months for my Intex Cloud Fx , which is up-to-date to 1.3 I then realized that a new version is under development (Firefox OS 2.0 unstable), still I am stuck with the same touch lagging operating system even though its stable. It was hard for me to get the adb working without the android sdk installed ,by searching for the right driver for Spreadtrum sc6821 for windows. Once I paired it , the Webide worked fine with the phone and I enjoyed the app install experience! My main censure is that I do not know how to install my own build of Firefox OS(OS currently in GitHub, code name Tarako Supported) without unlocking the firmware device(by the way the carrier is unlocked). Developers mentioned in the Firefox forum stating that, my device is firmware locked. Here is the question, there are tools for the ZTE variants for unlocking the firmware but is there a tool for my device ? I had googled couple of times and searched various forums but I could not find it! There is no hope of my device getting an official update! (Intex has a worse reputation as a Smartphone provider, still I bought it for the hopes of Firefox OS ecosystem )
