As is, you can't dirty Santa. But I'm not familiar with all the downgrade options. Do some research. You might be able to downgrade to a version that can use dirty Santa. Maybe someone here on your version knows. Also the answer probably is here in this thread somewhere. It's an awesome device when rooted. Best I ever ran and I ran a few. Good luck.
[LG V20 Guides, News, & Discussion] RBEmerson:
Thanks for the reply. :)

With 344 pages, reading them one by one is ...um... not happening. I did search for US Cellular and nothing I found says how to rescue this thing. >:(

What V20 do you have and what procedure (not asking for step by step) did you use to root it?
[LG V20 Guides, News, & Discussion] Dr_DjEnder:
The anti roll back on 10n is 0 as reported on another thread via a hidden menu so you can probably use lgup / uppercut to flash a lower firmware like 10f is what I did dirty santa with just be sure to back up anything of value up

Mine came with a higher patch not exactly Nov 2017 / 10n but I downgraded it using the former method to 10f then rooted it.

hi, just got my LG V20 yesterday,

I tried to follow instruction on the first page

but when stuck at step 3.5

adb shell

is my LG V20 rootable with your DirtySanta ?
[LG V20 Guides, News, & Discussion] cityneversleepz:
Right you can't root unless you find a way to downgrade. You'll have to research or see if someone here knows if your model has a method

---------- Post added at 03:52 PM ---------- Previous post was at 03:47 PM ----------

You have the right security patch but it's possible that that variant of AT&T isn't going to work. But I can't say for sure. You could try to see if someone else with the same variant will answer you here

can't access bootloader LG VS995

Hey guys, this is my first attempt at rooting a device and I'm having a lot of trouble accessing the bootloader on my Verizon LG V20 VS997. I have downloaded all the files listed in the above post and followed each step but can't get any of it to work. I've tried following Youtube tutorials and I'm not even getting the same prompts as the guys posting the videos. When I try to put it into the bootloader it just restarts my device normally. Maybe it's because this is my first time trying but if anyone else has ran into this same issue or knows what I'm talking about and you know how to get it, any help wold be great. Thanks

Hi, I got My LG V20 H910PR root by following instructions on this Thread https://xdaforums.com/v20/how-to/root-h910-v10m-t3664500

[LG V20 Guides, News, & Discussion] Ampicillin:
Search for KDZ extracter look for modem file if there's any and, in LGUP I think there are certain options you could google up.
[LG V20 Guides, News, & Discussion] runningnak3d:
[MENTION=4499573]atarashi[/MENTION] You said you made a backup.

Extract the h910-10r.zip file that you flashed. It will contain a bunch of files like (xbl, hyp, modem, raw_resources, etc)

You dump that you made will be a bunch of files like xbl_COMXX where XX is the COM port number that you used. You can ignore that -- just go by the filename.

Get into fastboot mode: with the phone off, hold vol DOWN and plug in the USB cable.

For each of the files that are in the zip do:

fastboot flash xbl_COMXX xbl

fastboot flash modem_COMXX modem

replace XX with whatever the actual number is.

Do that for all files that are in the zip. Do NOT flash an other files from your backup.

When you are done, you will still have TWRP if you don't let the phone boot.

When you are done flashing, pull the battery, and enter recovery via the key code. With the USB cable disconnected, hold vol down and power. When you see the LG logo, release power and then IMMEDIATELY hold power again till you get to the factory reset screen. Choose yes, and it will take you to TWRP. Format data, and then flash Magisk or SuperSU. You will be rooted AND on your H910PR firmware.

No matter what, do NOT flash aboot.

I doubt your going to get into ADB without accessing your phone first. I think recovery is your only option. This phone is easy enough to open from the back and fix the buttons. I think that's your only option at this point. YouTube has completed teardown.

[LG V20 Guides, News, & Discussion] cityneversleepz:
It's a supported device. Just make sure you're security patch is a 2016 date. Then follow the steps in the OP. once you are rooted you'll have many options to remove bloat possibly by just flashing a custom ROM. I like magisk root and a bloat removal module that works very well.

any other way to flash 'just' the modem?
[LG V20 Guides, News, & Discussion] runningnak3d:
That isn't the partition name...

This is what you are typing:

fastboot flash xbl_COM9 xbl.bin

This is what you need to be typing:

fastboot flash xbl_COM9 xbl

You can't flash just the modem -- well you can, but it isn't going to work. The H910PR hardware is different enough that you need the full firmware stack.

hello,

I just got my LG V20 LS997 but it's software version is LS997ZVA

is there any way to unlock bootloader? or can I roll back the software?

thanks in advance for your answer!
[LG V20 Guides, News, & Discussion] Ampicillin:
I own F800L. DirtySanta works but do not flash boot image part it will give static screen. Instead flash Swiftchy kernel and it'll give SuperSU root access and also lag free device.

If you want to remove bloatware, install Titanium backup. Backup all system apps and remove one by one and if error comes up just restore the app. If you do, please let us know also

is it still working with the LG V20 H990DS? I can get one for about the price of an xperia xz1 here which makes it an interesting option if it's stilll exploitable.
[LG V20 Guides, News, & Discussion] emdroidle:
The H990* family have a slightly different procedure due to different hardware. Notably rooting a H990* requires replacing the kernel with one which fixes weaknesses of the DirtySanta bootloader, and fixes the "static screen" (which is otherwise much worse than any of the US models). There is a thread for the H990.

You'll have a few choices. Not many. Very little development for our Sprint model. Check out classic ROM for a great stock experience and lineage OS for AOSP. Still worth doing it if you can get through the process.

Right, it won't work. Downgrading might be possible and that was discussed somewhere in this thread. Look for loopytea posts. This method is final as far as we know. Development for the v20 was very short lived because DEVS bricked trying to get past some anti rollback software on the device

[LG V20 Guides, News, & Discussion] cityneversleepz:

does ANYONE have a problem being UNABLE to remove ANY system apps (bloatware) ?

I have properly rooted phone. Every root function works except for removing system apps.

I tried multiple apps and they all fail to remove them.

Some would say "successfully" but its not removed.

Some would say "failed to remove"

No matter what system app remover i use, they all have same result.

I tried rooting with supersu and MAgisk, same result for both. No difference what so ever.

PLease help me.

It started doing it just recently. I never had this problem before.

I rooted exact same KDZ exact same root method with same files etc yet for some reasons doing it 10 times on the same phone is not produced different results as well as other issues i have with other apps.

I tried to wipe the phone, reset, KDZ reflash no help.

Any ideas ?I use Verizon. Downgraded from 15A to 13A in order for this to work (obviously required to do so)
[LG V20 Guides, News, & Discussion] cityneversleepz:
When you tried it with Magisk (module) Debloater) which terminal app did you use? After command su, what terminal command did you use to bring up the list of system apps?
[LG V20 Guides, News, & Discussion] tonycstech:
What are u talking about ?

I dont use modules. I downloaded some kind of (and the only of its kind that i was able to find) module that does not seem to do anything at all.

I am talking about apps like system app remover ROOT.

Before i was able to remove everything and now it does not.

Please understand this: (forget about magisk please)

Phone is acting more and more different each time i flash firmware and root it.

Right this moment, i reflashed again, unlocked bootloader, booted into TWRP and i get black screen saying Jump to XBLRamDup Mode. (or something)

I am using LGUP to flash and i think its not working properly because i get different results each time.

NOt to mention, when i reflash using LGUP, i get different bloatware preinstalled. How do u explain that ?
[LG V20 Guides, News, & Discussion] cityneversleepz:
You said you tried rooting with superuser and MAGISK. unfortunately, you didn't go far enough with magisk and for others reading this, it isn't a failure of the magisk module called "Debloater". That definitely works when it comes to removing system apps. I've personally removed several that way.
[LG V20 Guides, News, & Discussion] cityneversleepz:
For anyone wanting to uninstall system apps including priv system apps:

Install Magisk latest version currently 5.6

Let magisk install it's framework currently 16.0

From magisk downloads tab install Debloater and reboot. Go back to magisk app and open your modules tab. You should see the module you just installed - Debloater. Now open a terminal, su # then type debloat . Follow the easy instructions from there. Profit

[LG V20 Guides, News, & Discussion] cityneversleepz:
That could be fine but without seeing your device I can't be sure. You can try rebooting again but this time put something over your screen. Actually as long as the proximity sensor is covered that might be enough. But I would just go dark 100% room covered everything. Then give it a decent amount of time and hopefully it will turn itself off. Once it turns off you might be ready to use the Rom. Hopefully that's it.

Query: Currently running the 10r firmware on a F800k (because that's the latest version rootable by DirtySanta and I don't have a KDZ of a higher version). Before rooting, I upgraded to the 10z firmware only to discover that it was not rootable. I backed up that firmware using LG Dump, downgraded to 10b, upgraded using OTA to 10r, rooted with DirtySanta, then installed magisk.

Can I take the modem and boot files from my 10z dump and flash those with the 10r current firmware along with magisk? So that at least the kernel is upgraded.

I have the v20 us996 unlocked model and would like to root without voiding my warranty. I know I can unlock my bootloader and root that way but then I lose my warranty. I'm on the December 1, 2016 security patch so it should be vulnerable to this method, Would this work or will I brick it? Is there instructions for rooting this device elsewhere? I've had one user suggest that it should work but I don't want to brick it. Thanks
[LG V20 Guides, News, & Discussion] cityneversleepz:
It 100% works for your model and security patch date. If you follow the steps exactly, you will not brick. Look for YouTube videos where they use this method and watch them to the end before doing anything. At least one, if recall makes mistakes and then corrects them so if you followed without knowing, you'd possibly make them too. Rooting is worth it. I'd go straight to Alpha rom and install it after you gain root. It's the best that's been out there in a long time.

Your warranty is void though but that's with almost any root method unless you can revert.

I have a sprint phone I got everything flashed but it just boots up to static and i cant control the screen to get into recovery through adb. Also i cant use the hardware keys because as soon as I turn the phone on it shows that warning about not booting. Any ideas on how to get into recovery, or when I should push the power and vol down to boot into it. thanks
[LG V20 Guides, News, & Discussion] cityneversleepz:
The static is perfectly normal. Reboot by pulling the battery and powering back on. Either use your finger and cover the top left corner of the screen ( the proximity sensor is just to the right of the front facing camera) - you MUST cover it completely for several minutes on first boot. You can even put it inside something that will be completely without light for 10 to 15 minutes. The screen will finally turn off. Once it turns off, it's ready to use. For Sprint, I'd recommend flashing Classic Rom once you've got this working. No static and it runs very well. From there you can search for a good rom that gets updates or just stick with Classic. Once that screen turns off you can easily get to recovery. One very easy way is to install titanium backup. It has a reboot to recovery option. the key combo will work too.
