Has anyone rooted their LG G4 I would like to try and update my os,  I'm a bit nervous because the last time I tried a factory re set It wouldn't boot and had to have a new motherboard as it a common fault on the G4.  But lucky as it was covered by warranty and had to send it to Auckland and they installed a new motherboard and its like a new phone with out the updates! 

But just curious if any one has any experience with the procedure, or are LG phones locked so as can't be rooted?
