Chainfire has released a rooting file to root I9505XXUAMD2 firmware on the Qualcomm Samsung Galaxy S4. The CF-Auto-Root for Galaxy S4 i9505 LTE can now be used to root your smartphone. We also sawanother root coming for SGS4 i9500 but since the device has not started being shipped, it can't be confirmed. But this one is coming from a popular developer of widely used CF Auto Root.

Those of you who have got test devices can use this to get root access. But do not try it on i9500 since this would only work with SGS4 i9505 models.
