I currently have a g4 version h81220u and I want to downgrade back to Lollipop. Guides on xda tell me that I need a lollipop kdz and i was wondering if a h81210f would do the trick. I know 20x means MM and 10x means LP but I do not know if the "u" and the "f" make a difference. Help is appreciated

From what I understand, (google search did not return ANY results for "h81210u") when downgrading, just start with any stock KDZ H81210x ?? I'm not 100% sure.. That's why I bumped this topic.

HELLO guys I recently bought an LG G3 2do hand but it came rooted, so I want to go back to stock, it is runnig lollipop 5.0 I don´t know how to do that, because there is a lot of tutorials but altmost all are for kit kat versions, so please guys if you know something about it please let me know, and would apreciate if you explain it in many steps as you can, or guiding me to a lynk or video where I can watch it.. Im native from mexico so if it be in spanish I will apreciate your time, if you cannot translate to spanish there is no problem I will try to do my best..
You'll need to use either the KDZ or TOT method to flash back to stock...

Hi Folks
After running 6.0 MM (UK G4 H815 unbranded) for a week or so, Im finding it not quite a good as LP, and Ive noticed the only kdz file i xan find is v10d, but theres a few more 511 revisions until 20A.
Ive read up on Reburbish mode on LGUP, but is it possible to downgrade to or flash the last LP revision before MM, isnt it 10m or something..
Once 10d is "reburbished" on my G4, an OTA will take it straight to 20d..
Is there a way to stay with final LP
Thanks
Hello everyone.
I've updated to marshmallow recently but i want to try rooting the phone.
I want to do this without unlocking the bootloader because I don't really know how much trouble LG will give me with warranty issues.
So I've found a couple of guides here and there about using LGUP to flash a KDZ file. For the H815 model there are many different versions with different country codes. Does that matter? I have a Dutch G4 but I see the Polish version being much more recent. What difference does that make? Or is it better to flash the Open version? They do not seem carrier branded.
Is it even possible to downgrade?
Thanks.

How do I downgrade LGG4 H812?
Android Ver: 6.0
Software Ver: h81220X
I dont think I can root the 6.0 right now, I've been looking around and it seems like I need to downgrade?

using KDZ file and LGUP as long as its okey to downgrade on mine tmobile h811 we have antirollback.. so first you got to make sure search and read. if people have downgrade.. they are in atiroll version V0-V1-V2-V3 so if you in V3 you cant do back to V1-2 if your phone doesnt allow you to.. as am not sure but i think some phones have 0 always. meaning it doesnt matter.
I have the Canadian G4 which is H812 and there is no anti-rollback features. Check out the Canadian thread under the G4 general forum for more information and instructions on rooting. For downgrade you can use the files from that Canadian G4 thread but if you search for the LGUP thread there are good instructions for downgrading using that program which some have said is safer and less risk of brick.
