Dropped to 2G

Hi Mates,

Yesterday I made some changes to my LG G4 H810

Succesfully instaled Xposed with 3 modules

Youtube adaway
Greenify
Smart Network (All setttings turned off)

And Also made this tweak to unlock Hotspot

But Now my phone is only working on 2g EDGE, already watched network settings and is configured to work on LTE but I don't know whats going on...

Any fix?

Or

Maybe I can flash my rooted SYSTEM or my system img to go back to stock?

Thanks!
