I picked up this phone on Thursday because the Rise I had started boot looping. I was able to root my phone by following the same steps as on the below link.
Ok, so the link I posted here is now dead. So instead, I am posting a step by step tutorial. Keep in mind that I did not come up with this procedure. The thanks all go to other people.
1) Make sure you have USB Debugging enabled by going to Settings>Developer options. USB debugging should be checked.
2) Download Poot from the following link:
http://db.tt/0HqxEURT. I downloaded this from my phone and my phone put it in the Download folder on my SD Card, but you can download it onto your computer and copy it to your SD Card.
3) Download Ministro II from the Google Play store.
4) Download Superuser from the Google Play store. There are several, but the one that works for me is the one created by CHAINDD.
5) Run Poot-debug(W100).apk from your SD Card. Run the Poot application. There is a button at the top called "Press here to poot".
6) Poot pushes su to xbin.
7) Open Superuser application. Slide the screen to the right, going into the "info" tab. Under the "su binary" section, hit the "tap to check for updates" and update binary.
8) If done right you now have root. You can check by installing an app such as Titanium Backup and opening it. It should request SU permissions.
If you have any problems with this, restart your phone and run Poot and Superuser again.
I did end up with one problem where applications were not requesting SU anymore. I just went into Superuser and updated the su binary again to the newest version.
