Root and TWRP After 20i Update

Hi all, new to the G4 and had a quick question. The day i bought my G4 the MM update came out and updated overnight. Im looking to get root and TWRP on the 20i update and I'm having some difficulties finding a guide on how to accomplish this. I have read through autoprime's guide on how to OEM unlock but I'm not positive that it applies to me in my situation. Can anyone verify that his method will work on a stock 20i ota rom? Thanks in advance!

i echo this request. any help much appreciated

you need KDZ and LGUP. look here. i know 10n its lollipop
20i its marshmallow and latest its 20o. are you planing on rooting and use twrp.? if not you can only root 10n with locked bootloader. so you need to stay on 10n.. or upgrade to 20i MM. but do not flash 20oMM and go back downgrade to 20i- or 10n it will brick phone.
you need drivers-LGUP and KDZ. i think in the links you find everything

root can be on locked bootloader on 5.1 only using rooted system.img
10n and 20i antirollback V2. you can flash this 2 if you stay there.. 10 is lollipop and 20i is MM.
20o-20p-20q-and latest 20R is antirollback V3 you can switched to any onf this once you flash 20o or higher.
you cant unlock bootloader if you are in lollipop.
you need to be on 20i and do the procedure.

didnt you see he says hes phone says is a sprint..
(when upgrading i've seen an ls991zv6 i don't know)
either hes board is not h811 tmobile and flashed a h811 kdz to sprint phone..... or he has a h811 and flashed a sprint kdz..
i have not seen this on G4 in G2 yes alot of places would say it was d800. in stickers and all but the motherboard were replaced with anothe variant. so a phone put up togethe of othe phones parts..

well... here am not so sure.. like i said in LG G2 there were franken phones made from different parts of other variatns.. but the motherboard was the one to pay attention to. the only way was to open phone and read the motherbard. as they could edit the numbers in software but not on print in motherboard.... this is so odd tough i have not heard this on G4... likei said i dont know what the other guy did. did he downloaded a wrong KDZ.? of did he had right KDZ and motherboard not matching H811. ??? only way is to read the model name number in motherboard..
i dont know... when i got my phone it had 10n lollipop.. never seen m or h. i know theres kdz in a page but i have never use..

he flashed 20i ( (h81110m build lmy47d)
after upgrading it with LGUP + kdz img file H81120i_00_0201 (to mm) ) his build # is same as mine..... my board is msm8992 does it matches with yours or its fake hardware... @MicroMod777 H811 One Click TWRP will this method work on 81110m?

i see. i was helping there as well. but since i have not had USBHBULK and since then there was no way to fix. i see now they have some thread about unbricking.
i had that same brick on LG G2 but running KDZ. fix it on G2.. i think here is a different way with G4.
i wonder if that is the same situation. changed motherboard. and am not really sure if motherboards can be use in different variants.. only way is to physically see it.. but since you have warranty. then you are good.

am puzzled... i know in G2 they did that.. so could that be the case here.??
that doesnt help.. that app.
as i already told you. in G2 they can change IMEI and model number.. outside of phone would be a at&t housing then removing phone apart would show other model number for behind battery housing.. so they can edit software it could say d800 in about phone and version , ect d800 housing . but motherboard would be sprint...
guys am just sharing what i have seen in G2.. am not saying its same way.. its just my opinion and my toughts . what else could it be.??
nooo that program does not help. they can edit software info.. but not motherboard printed model.. what am saying is.. to make sure you have a real h811 in case they are building phones from other variants.
is to open phone and physically see the motherboard printed number.

yes since 20i-20o-20p-20q-20r-20v all are the same. procedure.. we use the 20i procedure it came first.. BUT dont flash 20i when it ask you to.. since you already in 20r you will be doing this same procedure in 20r so step that says to flash 20i skip you have 20r firmware already... make sure you have LG drivers and for fastboot i used mininal fastboot adb.
