Help me, please. Point me in the right direction (H918) - LG V20 Questions & Answers

Okay, first off, I've looked around for guides but only found ones dated years back, so I'm sure if they are still relevant (I don't want to brick my phone).
All I'm trying to do is install TWRP on my phone, I've only gotten as far as unlocking the bootloader. Maybe I'll root it later but for now, I just want TWRP installed.
Someone please help (be newbie friendly?)

This one?
Yeah, that's the one I found originally, it looked super promising but I'm stuck at two spots that he doesn't really explain, like the following:
"You must have a version of laf that has the COPY opcode." -I have no idea what that is/means, or how to even check that.
"This is NOT a guide for flashing KDZs -- there are plenty of those out there -- search." -I've searched, really. I searched "Flash KDZ H918 10t" and only found guides for 10r and earlier, and then the one 10t guide I did find wanted to have my phone already rooted... which brings me back to square 1.
I might be asking for a lot here, but I figure someone out there can guide me.

I recommend you go back and read through the thread thoroughly as numerous people have been able to root their 918 on the later firmware also there's an laf what is it thread you should check out as well

So he did put a link to the KDZ you need. Later on I'll give a Dropbox file for LG up and uppercut. Not at my PC right now.

FRP Locked LGV20 H918

Reading up on some things, Maybe I could flash it back to stock using LGUP (Not sure if i can do that without usb debugging and dev settings) and hopefully use dirtycow? I have no idea

I worded that really weirdly, sorry LOL I mix up my sentences quite a bit :laugh:
There's plenty of guides online to bypass frp lock. Not sure of the legality of it, but there's quite a lot. I would look around on YouTube first.

Depends on the model. I've heard H910 doesn't have a kdz. If you can find a kdz for the phone, you can use LGUP or something else I've heard called UPPERCUT, which is the same as LGUP but better in some ways... I haven't done any flashing, especially since just unlocking the bootloader on my model is nearly rocket science.

H918 does have some KDZ's but I can't seem to find one for H91810D
This is the closest i've found so far. https://build.nethunter.com/misc/h918/v10d/
I have 0 clue how to flash that at ALL.
There's plenty of guides to flash kdz files. Wish I could help, but like I said, I haven't done it myself. Search around, see if UPPERCUT is better.

Just purchased an H918 10k - should I take OTA update?

Is there anything I should know in particular to 10k? It sounds like rooting isn't enabled unless i downgrade to another firmware version (is it even possible?).

Yeah don't update. You need to downgrade which is possible.

Same thing with me. Recieved h918 with 10k. Downgraded to j, unlocked bootloader, flashed twrp and custom rom.
Is there a specific page you'd suggest for me to follow our search term? Sorry I'm very new to this and thanks.

Find the post with LGUp (restore even for bricked devices) and follow the instructions to downgrade. There are also some youtube videos which are very helpful, in order to downgrade or after, unlock bootloader and so on..

Need help to root H91810k

Hello,
First off, thank you for clicking on this post. I'm new on XDA and rooting LG phones. However, I've searched help on posts and other sites on how to root LG V20 H19810k (T-Mobile Variant) and many told me to downgrade first and then root. But none exactly gave any instruction or step by step on how to do it.
My worries are these ARB (Anti-Roll Back) software updates and if you were to downgrade, you will brick your phones and things like that, it's LG (I mean like there are a lot of complains about hardware faulty after phone updates and lawsuits about it), and different steps on each variants. I bought this phone like 2 or 3 months ago, and my thought on this phone's software is sucks so bad. It's so bad, I've had many problems like my mobile data often times stopped working (no network) even though signal is full bar, my live pixel background suddenly gone after playing this specific game, serious low fps in some games, RAM is full all the time, and many more. The phone itself has amazing hardware and specs, but damn why is the software so bad?
Right, so all my problems aside, I think switching ROM or downgrade probably a good idea and rooting for removing bloatwares. But many had problems installing twrp recovery to root and risks like bricking and bootlooping. And in this post, I'm hoping for help to downgrade and root H91810k.

Search this forum there's numerous threads on how to root
Sent from my LG-H910 using XDA Labs
Downgrade to 10j and use DirtySanta, or use lafsploit.
IMHO they are about equally difficult. In the lafsploit thread, I state that you have to be on 10p or 10q, but I will update the post stating that you need to be on 10q or LOWER.
DirtySanta doesn't require you to use FWUL, so it does have that advantage.
Bottom line though, you can't stay on ARB 0 firmware and use any of the current ROMs -- they all require 10p or higher firmware.

Thank you for the reply,
Seems I got it a little bit. So what I've been looking at this dirtythis and that unlock stuff for quite a while. I've been wondering if anyone asked about H918. I just realized that this dirtysanta bootloader is an exploit for other variants that don't support unlocking via fastboot.
So then I proceed to unlock my device and it successfully unlocked. (Follow this post to unlock).
I will try downgrading my device via lgup and will follow this post to flash and root.

Be careful about your rolling back to root, check your current software version and and if you're arb 1 you'll brick. If you're arb look up the laf exploit thread

He said he is on 10k, so he is safe to rollback to 10j which can use recowvery.
@ignoll Whatever you do, DO NOT flash the engineering aboot, or you will brick your phone. Follow the procedure in the post you linked, and you will be fine. DirtyCow gets you a temp root shell that will allow you to dd TWRP onto the recovery partition. If you get an error when you do run-as con, then you are NOT on 10j or lower. If you try to downgrade and you get an error about ARB, then you are NOT on 10k.
Just keep all that in mind and you will be fine.

Thank you for the reply,
Just to make sure, 10k is the software version which you can find in the software info inside the settings app, right? This software info will show stuff about "Android version", and down on the list, there's the "Software version" and below it is the 10k coming from (H918xxx). Or, check it via svc menu and version info through the dialer app. All that is to check whether I'm in the correct version or not, yes? (Sorry for this silly question, I just want to make sure. I'm really new to this)
And yes, I won't flash this engineering aboot, just follow the instruction and I'll be good. But just to make sure again, there's no this "engineering aboot" thing in the post that will brick my device, yes?
That said, I really appreciate for your warning and advice.

Yep, that means you are on 10k, so you are safe to rollback.

Please, i am also stuck and confused, as i understand LG devices, downgrading may cause device to go dead completely, i want to be sure before i begin this process. Here is my device Software Info:
Software Version: H91810K
Build Number: NRD90M
My device is locked to T-mobile, and i want to unlock using Octopus Box as i have credits. Unlocking requires root, is it possible to downgrade to the mentioned version 10j and not brick device? Any one can help me on this.

If you root your phone it will be unlocked no need to use an octopus box.

That is only true if the engineering bootloader is used. The H918 still needs work to get it carrier unlocked.

LGv20 US996 Root, Trying Dirty Santa, Now I am stuck at trying to configure LGUP

I've spent the past 3 days trying to root my LGv20 US996. Apparently I purchased one that isn't capable of being rooted by the official LG website. When going through the dirty santa hack, I just discovered that my phone has been patched and the hack no longer works. I've read that I can flash 12a using LGUP to then apply the hack.
Goodness this is complicated.
I can't seem to figure out how to configure LGUP or find the 12a firmware. Can anyone help? I am reading the guides for LGUP and when I load the program it asks for passwords, countries of origin, all sorts of stuff. Also I can't even seem to find the appropriate 12a firmware.

Is the LG G4 H81220x MM rootable?

Sorry if its too much of a 'newb' question, but I've been reading up on this for days, and I'm still not sure, if there is an exploit for the h81220x (Marshmallow, Fido/Rogers(?)) variation of the LG G4. I've seen messages from 2017 that say "not yet, for this one anyway", so it's all quite confusing. I only want to install a ROM with as late a version of Android as possible (beyond MM). I know the bootloader is hard as nails to crack, and there are alternatives, like "USU", and one wrong move and this thing goes into a permanent bootloop. So is it now doable for a Fido-branded G4 with the H81220X firmware installed, and if so, which would be the best / safest method to go with? Thanks!
