Downgrading and Upgrading questions



Hello XDA.
I've got the LG G3 D855 and I got it with android 4.4.2 and than I upgraded it to lollipop (right now I'm with v20H) and I knew that the device is capable with 4G so I talked with my carrier and I finally had the 4G enabled on my phone.
But I suddenly faced the bugs of lollipop and I decided to downgrade back to 4.4.2, it was alright but the 4G capability dissapeared of anything even in the menu there was no option for LTE :( so I upgrade back for lollipop again and it was ok and I got my 4G back :good:
So my question is why did it happened ? and I want to know what to do if i'll downgrade back again and still have the 4G enabled and not lose it.
Thank you.
