Its been rooted with Kingo v184.108.40.2060 and has downloaded Kitkat 4.4 Software version N900VVRUCNC4
Is it safe for me to take the upgrade with the phone rooted?
If not, should I attempt to un-root with the same version of Kingo, a later version of it or something else before letting the phone take the upgrade?
Do the problems with not being able to write to an SD card still exist?
Is there currently any way around this?
Thanks for all advice
