Default [Q] Hoe to root Alcatel One Touch Fire

Hello everyone.

My english is not so good, so forgive me if I make a mistake somewhere...

I am from Serbia, and I have Alcatel One Touch Fire mobile device that I have purchased from Telenor with postpaid agreement.

Version of Firefox OS on my device is Firefox OS 1.1.0.0-02009A that I installed as standard upgrade. After that, I have problem which is reflected in the inability of show me name of caller that I have in my Contact. So, I can never see the name of the person who called me, whether I have it or do not have the contacts, I see just phone number. That frustrate me very.

I've seen versions after 1.3 have a number of improvements, and I wanted a newer version of the OS to install, but do not know how.

I do not know if it's Telenor locked the phone and whether they can install the new version of the OS.

Any help is appreciated. Thanks in advance.
