If your intent is to root, you'll need to downgrade to a security patch prior to Dec 2016 you can use LG up to flash a kdz, then use the dirty santa exploit to unlock the bootloader and root.

Since you have a 990ds you can downgrade with no problem because anti rollback has not been incremented on the 990. You can find kdz files for your device at lgfirnware. Com. You should be able to get lg up software from LG's website.

I'm making this thread to have a centralized location where people can come looking for stock OTAs and flashable monthly security patches which our device gets.
Stock 6.0 MRA58V (Thanks to @AC DC for these)
For White variant : https://r3---sn-85po58p-itqe.gvt1.c...d745d585625bd9c565ce9e80693.s031-full-ota.zip
For Gold variant : https://r3---sn-85po58p-itqe.gvt1.c...587bf89bff5bdaa8b444b398bff.s110-full-ota.zip
Security Patches :
I am putting up the link grabbing procedure for OTA updates here so that anyone can help me keep this index updated
1.When you get the notification, download the OTA but DON'T install it yet.
2. Fire up a terminal, go root, then type :
Code:
bugreport> /sdcard/ota.txt
3. This will take some time (two to three minutes). When that's done, type this in :
Code:
grep system_update /sdcard/ota.txt
4. You should see a similar screen : http://i.imgur.com/9ywII0q.jpg
5. Only common sense is needed from here on
NOTE : I manually remove all verifications from each security patch I upload here, so the signatures will be broken.
Security Patches :
WHITE VARIANT
March Security Patch : https://drive.google.com/file/d/0BwL6sFI5X7ahcFJZVENMU3A1ZWs/view?usp=drivesdk
April Security Patch : https://drive.google.com/file/d/0BwL6sFI5X7ahMEt5bXR6U2ZWZUU/view?usp=drivesdk
May Security Patch : https://drive.google.com/file/d/0BwL6sFI5X7ahUHhjYmktSDFwTW8/view?usp=drivesdk
June Security Patch : Google couldn't care
July Security Patch : https://drive.google.com/file/d/0BwL6sFI5X7ahclFHcWhTZnczcnM/view?usp=docslist_api
@aaryan45, if you can contribute links for the Gold variant it'd be great!
HOW TO INSTALL THE FULL MARSHMALLOW OTA CORRECTLY
Google shipped out a buggy updater-script with their marshmallow OTA update so you cannot simply flash it normally without any modifications. You will have to replace it with the one @AC DC provides in his thread here : http://forum.xda-developers.com/lav...-to-upgrade-to-marshmallow-bypassing-t3315319
HOW TO INSTALL A SECURITY PATCH CORRECTLY
This may not be a question for some people, but there are some *complications* you must keep in mind. I remove ALL checks from the updater script. ALL. I do it to reduce flashing time but this also increases the chance of you ending up in a bootloop. There's only one thing that has been an issue for me as of now, and that's XPOSED. Uninstall it, flash OTA, boot, and install xposed back. In my case I just wiped my system partition, then installed stock 6.0 full OTA, then March and April security patches and it worked. Please make sure to use systemless root whenever possible and REINSTALL it after each OTA or patch.

If you're using systemless root, you can restore your stock boot.img and go ahead with the security patches, otherwise it's a full system restore first. Use the full OTA links on the first post to do a full system restore if the need arises.

The updater script has to be replaced only for the OTA 5.1 -> 6.0
The terminal method is to *grab* new links of the security patches that arrive each month. The patches I provide need no changes, just download and flash.

Typing those commands will show you the link from where the update was downloaded, you will have to post that link here so that I can mod the updater script to make it TWRP flashable.

Thanks for the appreciation! The white and gold variants differ in the button placements, since the gold variant has capacitive touch buttons at the buttom for navigation while the white variant has on screen navigation buttons. The Pixelv1 received the 6.0 OTA, then subsequent security patches upgraded it to 6.0.1 . I'm still waiting for the June patch, if you can go back to stock (I can't, testing out CM13) and see if it arrives. Use the steps in post #2 to get updated to the May security patch (you won't get June OTA without it)

I've been looking to root my phone, but it has the January 2018 security patch and I read you can't root with the latest security patch unless you downgrade. So my question is, is there really no way to root without downgrading because I would prefer not to downgrade.

Ok so just to be clear, if this was a Samsung Galaxy, I would not be asking questions. That's my "safe zone".
So first, how do I update to 8.0? I'm rooted, using mk2000 kernel and I have Xposed installed.
Do I have to uninstall Xposed? Do I need to find the stock kernel?
What about TWRP? Does that have to get updated first?

I'd suggest if you want to retain root, wait for someone to upload it with a root patched boot IMG as far as xposed you probably have to reinstall after updating to oreo

What I don't understand is that with my Samsung Galaxy S5, all I had to do was gain root with Odin.
I never had to flash TWRP to flash any custom ROMs or any updates. I used mobile Odin Pro for all of that.
ChainFire developed FlashFire which does the same thing and it supports many devices. Not sure why it can't work with LG devices.

Can't say much about Samsung maybe @runningnak3d might be able to pitch in with his super brain.
The H918 never had full fastboot. It was rootable when it was ARB 0, because there was a kernel exploit that gave temp root and then you could dd TWRP onto the recovery partition.
As for the S5 and older phones in general, Qualcomm security pretty much didn't exist, and therefore Android security didn't exist (same for Apple and jail breaks).
Qualcomm has upped their game drastically by adding security into the CPU. Android and the OEMs take advantage of that to lock us out.
The TMO G7 no longer has an unlockable bootloader, and the V40 won't either.
If you want a phone that can be rooted with an SD845 chip, buy a dev friendly phone.
