I have found two ways to root Alcatel Onetouch Fierce XL so let's get started. Without An Computer: 1. Go into your phone settings and click on security. 2. When you enter security settings click the checkbox that says unknown sources (ignore the message). 3. Go in your web browser and click on this https://kingroot.net/wap and download the app. 4. Install it and wait for a message if it pops up and it says something about can't install don't exit the message just click more and it installs. 5. Click try to root and your phone is rooted.
