I currently have the LG v20 (the h910 variant running off of the latest update 10m) which apparently is not root able at this current time because of the latest security patch. Mainly my question is how do we go about about setting up a bounty thread for this particular device (within the allowed rules here) and would be greatly appreciative if someone could lend me a hand with this. Maybe two of us can maintain it or however bounty threads are handled.
H910 is rootable on 10m.
Search for the patched LG UP thread and I posted the full procedure, but the general gist is:
* Use patched LG UP to backup your current phone
* Flash H915 v10e KDZ (you will have no modem right now -- no worries)
* Root with DirtySanta
* Install TWRP
* Flash the modem that you backed up in step 1
You can now proceed to flash any rom for the H910 -- I recommend NATF, but WETA is good as well.
My H910 is with LG being repaired at the moment. I bricked it, but coming up with this procedure had nothing to do with it -- unrelated.
When I get it back, I will be posting 2 zips. One that will take you back to stock if you need to, and the other will flash the remaining partitions so that you are back to 10m (minus the eng aboot that is needed for root ).

According to everything I have read the h910 variant running on 10m, anything after December's security patch cannot be rooted without resulting in a brick. I'm getting highly confused on what is what at this point as I've heard many different things from different people and I also cannot find this patched LG up thread you have mentioned above? Is it not in the LG v20 thread here?
Link to patched LG UP thread: here
Dirtycow was patched after the December security patch, and that is why you have to flash H915 v10e which has the Dec security patch, and is still vulnerable to dirtycow. H910 is obviously not an H915, so that is why you have to fix your modem after you have rooted it.
AT&T is still on ARB 0 even with 10m. I am guessing it is because there are no KDZ firmware files available for the H910, so AT&T probably figures there is no reason to increment it. So for now (until AT&T gets wise of this and increments ARB), we can flash old firmware.
Do NOT flash just any variants firmware. For example, flashing an H918 KDZ will brick your phone. I am fairly certain that the PBL is the same on the 990, 990DS, 910, and whatever the Verizon and Sprint models are -- that is why they can all use the same engineering aboot. The US996 and H918 I believe have the same PBL. All of that is purely speculation though. The only cross variant testing that I have done and proven works / doesn't work, is the H915 and H918.
H915 on H910 - works, broke modem, fixable
H918 on H910 - Brick. Must go back to LG
-- Brian
So this method is not currently tested? I might be able to help if it hasn't been tested yet to attempt doing this on mine. I just have to gather everything I need to attempt this and make sure I got the steps down right behind I do
Oh yea, it has been tested. This is the second time I bricked my H910. The first time, when I got it back from LG, they kindly loaded v10m (yes, that is sarcasm). The first thing I did was check the ARB version, and when I saw that it was still 0 I started looking for ways to flash the H915 firmware. I knew it was safe to flash H915 on H910 from past experiments.
I was having little luck since LG UP *really* doesn't like to flash cross variant firmware, but then I came across that thread on patching LG UP -- viola -- problem solved.
Since H915 firmware is safe to flash on H910 phones, and v10e was still Dec 2016 sec. patch, I flashed, and rooted.
After that you only need to flash the H910 modem, and you have a fully working, rooted, H910 that had the April 2017 sec. patch.
Good luck. If you need any help, or get stuck (it really is straight forward), shoot me a PM (or give me a mention in a thread) since I don't subscribe to thread
Now when we see talking about the dirty Santa exploit method are we talking about this thread here?
https://forum.xda-developers.com/v20/how-to/v20-h915us996-dirtyelf-bootloader-t3568013/post71300441
I also found another thread similar to this one for the h990 I think it was
I think i have found the correct thread for the dirty santa method now which i will list below for reference
https://forum.xda-developers.com/v20/development/ls997vs995h910-dirtysanta-bootloader-t3519410
Is this correct?
Hi, I've recently moved on from my ZUK Z2 to V20 and I'm loving this phone. Recently discovered very little-to-none info about my puerto rican V20 though. Its H910PR v10j claro stock rom with 1st December Security Patch.
Can anyone guide me if there is a possiblity to root/TWRP this set with failsafe? I'm just noob to these recent terminologies about ARB/flashing etc for the case of V20. I have had G3 before but this V20 stuff is totally new to me.
Also, if in future, LG releases Oreo for V20, will the claro v20 get it?
Kind regards,
Since you are on the December security patch, you can use the normal DirtySanta root method.
As for getting Oreo, even if Claro doesn't give you Oreo, you will be able to flash the H910 version (if ANY V20 gets Oreo -- I am starting to have my doubts).

Thank you,
I pasted version screenshot from LGMenu. Please advice.
did you make it ?
any good news?
Can you please guide me how to manually update my AT&T v20 to be stock not rooted oreo, my h910 is stock never touched, not rooted of version h91010m which can't get updates as it is unlocked and am not in US.
All i want is just to update it manually to the stock oreo software.
Thanks a lot

Use this to root.
Instead of flashing the 10v att image like the last step suggests, use the 20g Oreo image instead
H910 Oreo 20g: https://androidfilehost.com/?fid=1322778262903991071
Thank @clsA for the Oreo link
Thank you
Thanks a lot for the clarification...
i have read more, i believe this rom will let me stock oreo so am worried i can't update the phone again in case of future updates.
is there a way to update in future? Also is there a way to change the software from h910 to h915 so that i can recieve ota updates normally in future?and is it safe as am afraid to loose signal or brick phone etc...
Thanks a lot in advance.

After you flashed the 20g Oreo image, it will be stock as if you took the ota update itself. You'll be able to accept ota updates after words. Follow the root thread, amd you'll be fine

The problem is i can't recieve ota updates even i am stock, it is AT&T restriction because my phone is unlocked am using other network (am not in us)
ota updates need to have a working AT&T SIM inserted in phone. It is very stupid policy for AT&T.
So my question now is, is there a way to convert h910 to h915 safely? Because Canadian operators allow ota to unlocked phones...
Or is there a way to manually upgrade in future after i upgrade to stock oreo?

why are you worried about updates when you can't take them now ?
Yes you can convert your phone to 915 it's the first step in the rooting process
if you want to stay 915 use the H915 Oreo KDZ > https://forum.xda-developers.com/v20/how-to/h915-oreo-kdz-link-t3826812
If you want a H910 on Oreo use my zip. If another update comes along their will always be another zip (provided we get root and TWRP for Oreo)
In case i will just flash the h915 oreo kdz, should i flash all partitions? Including modem, bootloader, etc...
Is it safe? Because in the guide it say i will loose the signal after flashing h915...
Also Should i still root first or can just flash directly?
Also is it safe to get future ota updates when software is for h915 and treat my phone as if it is h915 from the beginning?
Many thanks in advance.

You flash all partitions for non rooted stock which should work like normal with everything working.
My guide is for those trying to keep root intact so to preserve the dirtysanta eng aboot so there are problems with data at the moment.

I'm in the same situation as the creator of this thread, I can not update my phone from OTA
Assuming I do this to update. Would Android Oreo be rooted? Could I enter TWRP ?.
Since If I do this procedure and update my phone to Oreo and I don't have root or chance to get into TWRP . I would be stuck until there is some way to root the phone (if it comes into existence)
PS: I bought an AT&T sim card from eBay, but I couldn't activate it. Do you guys have any idea if the sim being activated I could update my phone despite not being in an AT&T network?

You will loose root and be back to stock bootloader so no twrp. It's stock oreo with no way of rooting it for now.

Just to clarify this statement a little. If you want to run Oreo now, you can't have root. However, you CAN downgrade back to Nougat and root when we finally have the Oreo + engineering bootloader issues worked out.
The US996 will be getting Oreo eventually, and that firmware is what is going to allow us to have rooted Oreo on models that use the engineering bootloader.
If the US996 wasn't getting Oreo, then I would waste the time trying to get things sorted out -- but that is just a waste of time.
We have waited for Oreo this long, waiting another couple of weeks isn't going to hurt.
As a final statement, I have had a chance to play with Oreo on my H910, and I am NOT impressed. What a ****poor, crap job that LG has done. It may get better with future updates, but I wouldn't bank on it.

I remember reading earlier this year about how LG was going to reform their mobile division, getting better at software updates and halting/slowing down the typical release schedule of phones.
Seems none of that has happened as far as I can tell, especially the software part. What a farce.
finally i updated my H910
i managed to updated my H910 by simply flashing the oreo H915 KDZ file with patched LGUP and it seems very good... signal is ok no errors so far except one after rebooting phone
ARB is still zero.
thanks a lot for all of you

Why do you think US996 getting Oreo helps? What if the eng aboot can't initialize the oreo modem properly (maybe intentional change)? I have a thought, maybe we can try if the stock nougat aboot, say H910, can boot the Oreo with data? We could flash everything Oreo stock and just leave the aboot nougat. Since signatures are still LG, it should boot up? And if it still can't have data, maybe eng aboot can never initialize properly, I don't know.
Questions about the H910 --> H915 Conversion
I have read several different postings on how to change the H910 to H915
I read the posting by runningnak3d and I am bit confused.
Sorry for the noob questions
1) If I flash H910 to the H915 v10e kdz, do I have to continue the steps to flash to oreo or can the phone be updated from OTA?
I really don't want the AT&T logos on my phone and I don't need my phone to be rooted or need dirtysanta.
2) Would flashing it with LG UP be enough to get Oreo?
3) I'm confused with the steps after downloading terminal emulator? - Do I need to do these steps if I want to keep the H915 Rom?
Sorry if my questions are dumb.
Thank you in advance.
Much appreciated

you can do as i did, just flash H915 KDZ Oreo file directly using patched LGUP and select to Partition DL all partitions.
you will have stock oreo H915 fully functional phone, there is only 1 error message that will appear every reboot of phone but will not make any harm.
there is no any issues or problems i have noticed so far, also the software seems more stock than AT&T version.

you can simply use lgup to backup your current setup (not userdata)
and use lgup to flash the 915 Oreo kdz
Note: someone said that converting to 915 caused google now to stop working but everything else was ok
if you want to return to 910 stock you'll have to do the root procedure and flash h910 10q or 20g back to stock rom from TWRP

Hi,
I currently have LS997 with ZV3 firmware which is rootable and dumped the whole system using LGUP before I do the dirtysanta on this.
Is it possible to use this dumped files to downgrade other LS997 phones with non-rootable firmware? (ex. ZV8 and up)
Did anyone try this before?
Thanks for reading!!

This would be a definite game changer if so that I could use myself. But unfortunately if I am not mistaking, I think (could be wrong) that firmwares are baked on the chips themselves so ARB is still an issue after implementation on ZV8.

I understand. Thanks for the reply!
arb is done with tiny electronic fuses that are part of the SOC (basically cpu) itself. Once the fuses are burnt there's no going back, the same fuse system also tells the SOC other very important things like "This is LG's signature and don't run bootloaders without it"
alright y'all, idk who's still kicking around but there seems to be a ton of **** all over regarding development non-rooted G5's and searching around for it all is a pain.
i'd like to put all that **** in one place so anyone coming along has all the cards and knows what's been tried and where to start.
what's the current status of all the non-rooted phones so far? let's compile everything together here and help get everyone with this excellent phone custom firmware!
currently i have a H820 running oreo i can dink around with. anyone else is free to join in.
LS992 with ZVF firmware on Nougat. Still no luck.
H830 stuck on 20A / 30C unable to root
I have an H830, anti-rollback level 1, can only flash either 20A or 30C KDZ image on, not possible to flash lower than 20A. Bootloader is unlocked but not possible to flash recovery via fastboot. recowvery method will no longer work with 20A apparently due to an LG patch.
My understanding is that recowvery requires 10j or lower but it's not possible to downgrade. ergoithz/magisk.g5.howto.md github page describes how bootloader on some models can be fully unlocked via official LG method to enable flashing recovery. Only G5 model that's listed is RS988.
Perhaps someone can modify the LG unlock.bin file to support other devices?
