Questions on the box

I am frustrated with my Z3x LG box which does not seem to be able to unlock any of my phones. Being new to the Octoplus box, I have some questions:

1) Is it easy to unlock LG phones like the MS95, L70, D415, and L90 ? Does it require any type of JTag or soldering, or is it a simple ‘plug in and unlock’ ?

2) Does it unlock software app phones like the Leon and Stylo ?

3) Does it repair IMEI’s on phones like the Stylo and V10 ?

Thanks for any help,
