[Q]Lg g stylo (h635) custom roms

Hello. I have been searching for a while but Is there any custom rom's on my lg g stylo h635?

Lg g4 h635 (stylus)

Recently purchased this little gem....only to be horrified about finding no info on root capabilities and/or unlockable bootloader..... my phone came with 5.0.1 but i upgraded to 6.0 thinking all would be well...

First off, is there a way to root this device??

Can the bootloader be unlocked like the other G4...or is it already unlocked?

Can I downgrade should the need arise? as in back to 5.0.1

i'm actually really stuck now and I kinda feel like I wasted my £££'s.... I already owned a G4 but this was all I could get my hands on.

Any help would be greatly received.
