Root HTC One VX Rooting

[SQA Engineering]

Hello,

I have an HTC One VX with 4.1.2 and would like to install KitKat 4.4.4 or Lillipop 5.0.1/5.1.1
(I am using appium for test automation)

So I have a couple of questions and would appreciate any help or pointing me in the right direction.
(I am using appium for test automation).

1) Has anyone installed either of these versions and if so are there any issues?
2) Which versions do I need to install, propagate through, to get to KitKat or Lollipop?
For example 4.1.2 -> 4.2.2 -> 4.3.1 -> ...?

Thanks

Gaspar
