Stock Firmware for LG V20 H990 - LG V20 Questions & Answers

I have an LG V20 H990 & I understand in order to unlock the bootloader & root the phone the security patch needs to be pre 2017. However, I'm unable to find the correct firmware & region for my V20 that predates 2017. Any help is appreciated.

Yes not much advice or help for the H990 V20. I wouldn't meddle with it if I'm honest, especially if it's your daily driver. Just install a firmware from a different region but same model number.

Lgup v20 h918

Hello i have the LG V20 64GB H918 10t I see lots of links to patches some to the tool but with the wrong .dll
I must be an idiot because i can get this working so i can update via KDZ and then use lafspot. I set up what i think is the right version of LGUP and patch.
I get DLL for H91810t is not properly installed. Any link to the uncracked and cracked h928 10t.
I hear ya man. I'm trying to find dll for 10p but no luck.

I have a question about H870's kdz file

Can i install the H870's Oreo kdz file using LGUP to my H870TR? The update is not available to me with OTA or LG Bridge. If i can install it, is there a guide to it? I looked through this forum and couldn't find anything.

yes you can, nothing will go wrong. Go ahead...
i did that with LG V10 about a year ago when i have H960A and flash a H960TR kdz so, will work for sure.
I advice you to wait because no one know if it works and how to restore in case of brick.

Need some help for rooting H990

Hello everyone, I try not to ask these kind of questions since people have already asked similar questions.
But I decided to verify some of the steps to follow rooting V20 on internet and I got confused a little bit.
Information about phone:
V20 Variant: H990 TR Single Sim
Android Version: Oreo (8.0.0)
Security patch: November 1,2018
Now from internet, it is as easy as rooting any other phone. ADB and TWRP, then proceed to your favourite ROM.
But when I look at DirtySanta it tells another story. (Also I have no idea if I will ever need KDZ writer)
So can anyone with H990 tell me how they have rooted their phone? After rooting I think it won't be a problem to go for Lineage 16.0
Thanks for reading!

Just follow the dirty santa thread for the H990, almost certain you'll have to flash a kdz to an earlier version to take advantage of the dirty santa exploit

Sorry I was out of the city,
In order to flash to downgrade I use the Patched LGUP, and I selected all the partitions, then the software ask me that some partitions will change and I click Yes, the phone runs incredible fine.

Lg h873 refurbished update

I bought a lg g6 here in bangladesh , it was refurbished , however the imei is massed up , imei.info says its a galaxy grand. In about phone it says h873 and if try to update my phone it wouldn't let me update saying phone is not registered yet, my question is can i update to oreo using lg up and be safe ? Or would it brick the device.. Current os version is 7.0
I have the same phone and it wouldn't update automatically so I did it manually
but I did not have the Galaxy problem
so flash at your own risk
