edit.. apparently i have ls99720a and theres no option for root..f

this is probably a stupid question but how do I tell if i have zv7 or zv8 or something else? Just got this phone and trying to get root
[LG V20 Guides, News, & Discussion] C D:
Sorry, you're already on Oreo.

In case anyone else needs to check, go to Settings and search for "Software info". Under "Software version" it should say "LS997ZV7" or a lower number than 7 at the end, and the date under "Android security patch level" should be no later than May 1, 2017.
[LG V20 Guides, News, & Discussion] smonnier:
The link to the VS995 "KDZ" (I'm new to this and have no idea what "a KDZ" is) is broken.

Any idea where I can find this firmware?

[ I have firmware ZV6 and am trying to install LineageOS on it, so I was hoping to follow your instructions. ]
[LG V20 Guides, News, & Discussion] smonnier:
Never mind, I found it by starting from "https://lg-firmwares.com/" and searching for "vs995". I think the corresponding link now should be "https://lg-firmwares.com/downloads-file/4889/VS99512A_06_1114_ARB00"
[LG V20 Guides, News, & Discussion] C D:
The link to the ZV7 firmware is now broken, so I have mirrored it in case someone still needs it:

I'm in the same situation. The hidden menu does not show an ARB version, it has the following options: Device Test, ELT Test, Factory Reset, Log Service, WVDRM Keybox. Any suggestions?

My Exact error is: Error: 0x81000402, TOT antirollback version is smaller than device version.

I'm on ZV8. I also want to add that the LGUP Version column in the application detects LS997ZV3, shouldn't it be LS997ZV8?

I never was able to find my ARB version either on zv9 then zva... Sorta why I took the updates never knew what arb I had so...

The option is simply not there.

I've been researching and have had no luck verifying which ARB version I have. Is there an alternative to the method linked in the third post in this thread? That hidden apk doesn't work on ZV8+
[LG V20 Guides, News, & Discussion] runningnak3d:
WIthout access to an LS997 I can't give you guys any more pointers unfortunately. If you look at the posts in the "Do you need help rooting" thread, there is one post that says ZV8 is ARB 1, and another that says ZV9 is ARB 0. So they either made up the posts, or typo (0 is a LONG way from 1 on the keyboard :) )?

Either way, if LG UP is saying that the ARB check is failing, then this may only be good for ZV7 or lower -- that has been tested.

WIth the LS997 not having a KDZ, I have to rely on you guys to tell me what ARB version a certain firmware revision is.

Until we can get to the bottom of this I am going to edit the title and first post.

[LG V20 Guides, News, & Discussion] vlad48:
Just to put some light here:

ZV6 and up has patched Dirty Cow exploit.

ZV7 has patched and reduced Sprint Hidden Menu

ZV8 is ARB1 (a lot of devs here bricked their devices trying to revert it back to 0)
[LG V20 Guides, News, & Discussion] runningnak3d:
Thank you very much. Since the ability to check for ARB was removed in ZV7, not sure how the people that told me that ZV9 was ARB 0 were even determining that.

I apologise to anyone who I got their hopes up for root on ZV8 and ZV9 -- at least this will work for ZV6 and ZV7.

[LG V20 Guides, News, & Discussion] runningnak3d:
Well, you can flash back to stock and see if you still have the problem. I have no experience with how well the LS997 works with the US996 engineering aboot.

As in this

https://xdaforums.com/v20/how-to/how-to-return-sprint-lg-v20-to-stock-t3665954

Or just running the stock rom? (I am on stock rom)
[LG V20 Guides, News, & Discussion] runningnak3d:
No, it is much easier than that. Well, are you running the stock ZV7 system image, or did you flash another ROM? If you are, cd to the did with the firmware that you dumped:

adb reboot recovery

Once in TWRP

adb push aboot /sdcard/

adb push boot /sdcard/

adb push recovery /sdcard/

adb shell

cd /sdcard

dd if=aboot of=/dev/block/bootdevice/by-name/aboot

dd if=boot of=/dev/block/bootdevice/by-name/boot

dd if=recovery of=/dev/block/bootdevice/by-name/recovery

If you aren't running the ZV7 system then you will have to push / dd that as well.

Reboot

Factory reset your phone, and it will be like you never rooted.

If you are still having a problem, you can then take your phone to Sprint and they will be none the wiser.

If you aren't, then the US996 aboot must not like ZV7, and if you want to root, will need to find someone on a lower firmware version that is willing to dump it for you. ZV3 I understand works fine with it.

Thanks. I am on stock rom from the dirty Santa thread. Zv3. And werewolf kernel.

2 questions. Because i just pretend that i have any idea of what I'm doing..

What does"dd" refer to?

And

"dd if=boot of=/dev/block/bootdevice/by-name/boot"

Is by-name to be replaced by what adb devices calls my phone?
[LG V20 Guides, News, & Discussion] runningnak3d:
dd stands for destroy disk ... yea, someone had a sense of humor. :)

It takes whatever is supplied as the input file if= and writes it block by block to what is specified as the output file of=

Actually by-name are just a bunch of symlinks to the actual devices.

For example boot is /dev/block/sde1

[LG V20 Guides, News, & Discussion] runningnak3d:
You must not have pushed aboot or your would not be getting the red triangle. The stock aboot is locked, so no warning. I am guessing you can't get to TWRP anymore? If so, yes, you will have to flash the vs995 KDZ and start over.

Ok I'll do it again but I think i did push aboot. I also just copied system to my ext sd card and transfered it because it was taking so long.

The triangle screen was slightly different then what I've seen in the past. it had a "press power button" message just above the normal message that says the device will power off at some point. anyways here is what I did encase this helps.

Or is it saying you have only 10 tries our something like that?

If that's where your at I think you can do a factory reset to correct it. I'm trying to remember. I ran into that scenario. I think i booted to recovery (power on holding vol down and power button. As soon as logo appears release power for 1 sec while still holding vol down then hold power down again with vol down still for like 5sec. Say yes to both questing.

I think that's how i corrected for that.it's real late here and my brain is fuzzy so no warranties expressed or implied and all that.

Edit: if you don't have twrp installed yet then to get to recovery you use the process i described above just switch to power and VOL UP instead

When you hear the voice at boot put your finger over the proximity sensor then press the power off just turn the screen off and the whole thing goes black keep your finger over the proximity sensor and turn the screen back on and the static should go away but have to do this for every boot unless you change the kernel or use a different ROM

Thanks for the help! I was trying to read through the entire Dirty Santa thread to find the fix but it's like looking for a needle in a haystack in there. I got my phone running the Sprint ROM, older firmware for now, but noticed that it doesn't have wireless service. I checked the network settings and a lot of the settings are missing. I wrote down the following network settings off of my phone before starting this whole process, maybe someone can use this. I tried to enter some of the missing values in network settings but it seems to be un-editable, I cannot type anything in the settings.

This current LS997 ROM should have something in the 4G settings, no wonder 4G isn't working. Since there's no way for me to edit the network settings in it, I decided to flash the most recent update of Resurrection Remix 5.8.5-OMS 7.1.2. I got LTE now and the phone is a lot faster and smoother. No more static screen either. I really like Resurrection, I always use this ROM during my Samsung Galaxy days.

DevDigital's ZV7 and Werewolf kernel.

What I did was flash Verizon KDZ, flashed the Sprint ZV7 in the DirtySanta thread, flashed various stock-based ZV7 ROMs, found out that they didn't have the modem included (kept getting no service, obviously), came back and got the ZV7 firmware (that includes modem) from the first post (might have tried booting it in case there were any post-flash scripts, bootlooped I think, naturally), then flashed DevDigital's ZV7. Everything here has Werewolf kernel attached.

Pretty sure flashing various stock-based ROMs can be skipped.

One last clarification,hopefully. After you flash the zip from this thread and reboot, did you have to boot into twrp or did you wait and your phone booted into twrp on its own? Thanks
[LG V20 Guides, News, & Discussion] lvlrdka22:
You'll be able to see in "About phone", "Network", "Mobile network type". eHRPD requires APNs, while EVDO doesn't, so if you're getting eHRPD, I'm not sure why you're not getting LTE.

Battery pull, then manually boot into TWRP.
