I know this is an old Post... But can anyone tell me if root is still achievable for the AT&T H910 variant or has the vulnerability been patched? ( I've had my V20 since January and don't recall taking any updates from AT&T. ) I tried the method described and can't get past the first step. It appears that Terminal emulator doesn't like my command of applying the Dirty Santa patch to the system. Am I just wasting my time?

Edit:

Crap!!! Just checked my software info. Apparently there was a security update in April. ( How did I miss THAT? ) Lol. Has anyone out there tried this recently and got it to work?
[LG V20 Guides, News, & Discussion] markmessier8888:
Yes please root for F800K it would be paradise and greatly appreciated!!
[LG V20 Guides, News, & Discussion] me2151:
Said it again in the last page. Dec 2016 or earlier. for security patch
[LG V20 Guides, News, & Discussion] mmmmmmmma:
Mark, try asking this user how s/he managed the rooting process for the F800K. S/he claims to have rooted his F800K with processes written by the OP. Also, check to see if your build number matches to what s/he says to have had before rooting.

And yes, I was able to successfully root my LS997 with instructions written by the OP.

Let me know if you have questions. I will try and be helpful. Good luck.
[LG V20 Guides, News, & Discussion] me2151:
Honestly just about getting there. I barely read new posts on here.

It SHOULD work provided there are little differences between the F800L and the F800K. I believe someone WAS successful in getting the F800K rooted using this method.

[LG V20 Guides, News, & Discussion] me2151:
If your securtity date is after dec. 2016 then you do need to downgrade to a version that is before the patch.

phone getting hot and green screen

Hey looking for a little help! Purchased a v20 Sprint LS997 for my daughter needed to be rooted. So I paid $35 to an online company to root the phone with dirty santa remotely over my PC. I know, should have done it my self but I was working overtime. The phone is now running hot and slow and during some heavy use, we got the green screen of death once so far. My question is can dirty santa be flashed again over the original install? The way it was done the first time took hours and I kept losing my online connection with guy so it was a poor install at best. I'll make the time and do it myself next time.Thanks James

BTW: I did pose the question " can dirty santa be installed again " in the search bar with no results.

Try a different kernel. Flash it in recovery

You can do Dirty Santa again and your bootloader is already unlocked so that's fine to skip in the instructions if you go that route.

I was successful downgrading to 10e from 10y.

I noticed 10e is for around sept.2016. Since we cant root past the december 2016 update, should I stick with 10e or upgrade firmware as close as possible to december 2016?

I noticed after downgrading to 10e that when I go into the update menu..it shows i can upgrade to 10i but I didnt
[LG V20 Guides, News, & Discussion] emdroidle:
For the devices where KDZ files are available, KDZ Writer is now available.

This is simply a program for updating /system and /firmware via KDZ file. While downgrading is currently the only way to get DirtySanta installed, afterwords you really should be on current firmware if possible.
[LG V20 Guides, News, & Discussion] markmessier8888:
Ok thanks

So if i downgrade to get dirtysanta installed, can i go back up to 10y without losing root?

I was previously at 10y but downgraded to 10e for rooting purposes but of course id like to be at 10y

It isn't taking the "apply patch" command.

It basically is giving me an example of what the command looks like.

Anyone know why?

Reinstall Dirty Santa root

Hey guys when Dirty Santa was first installed on my daughter's v20 I used the stock LS997 OS provided with the install instructions on page 1. I found a stock deODEXd-singed.zip also provided by me2151. Any info as to which is better? Or do I flash the stock one first then the ODEX in recovery or skip the stock one and just flash the ODEX version. Thanks Again James
[LG V20 Guides, News, & Discussion] me2151:
Should be fine just follow directions

the stock deodexd-signed one you found is a universal one that simunlocks the phone. just use the one on the first page or use one of my later ones
[LG V20 Guides, News, & Discussion] markmessier8888:
Ok thanks me2151!

If i am successful rooting will i be able to go up in firmware from 10t to 10y or will i use root?

I think 10y is the latest for the F800 model

YouTube has a couple of helpful videos "how to root lgv20". The one that's 14 minutes 13 seconds is a Verizon model. I think he covers it but it's been a while since I rooted. It's worth watching though. He's following this guide.
[LG V20 Guides, News, & Discussion] Ephemera:
Do not claim the device was stolen, the device was purchased and the original owner was in contact. I asked him simple questions which he refused to answer so I can aid him. You're just full of assumptions and accusations. He has no proof and if he did he could've supplied it upon arrival a full refund would've been his. Surely I did him a favor not involving law enforcement with the amount of evidence I have on the matter.

None that I know. Things that are not working have all been mentioned by OP in the first post I think. Other than that, everything seems working fine.

A valid point indeed. Come to think of it, I removed the /system installation on my current build and just have it installed as a user app.

So assuming that custom roms need to be the carrier specific right or can we use 996 roms on vzw?
[LG V20 Guides, News, & Discussion] me2151:
Should be able to use 996 roms. Keep in mind the device will think its a 996. And you will need to flash the boot2.img after and reinstall supersu. We cannot use custom kernels right now
[LG V20 Guides, News, & Discussion] Bread Bucket:
I did all the steps, including the very last step to prevent continual lag, battery drain, etc. But the phone is noticeably laggy still, anything I miss?

There will be some lag for a little while the device will be setting it self up and even out over a couple reboots

So this?

1. Flash 996 rom of choice

2. flash boot2.img

3. Flash SuperSU?
[LG V20 Guides, News, & Discussion] AlkaliV2:
This may be anecdotal, but switching themes to a darker one helped the lag on my device. I could not even begin to guess why or how (or if it just looks faster with a dark background) but it was noticeable enough that I'm mentioning it here.

I apologize for being a dirty non-search-bar-user... but thank you for the direction! This seems to have at least gotten me rooted according to a root checking app, but the phone feels really laggy now... :crying:

I see the note in the main guide that says "WARNING:This is a required step for non sprint users, it prevents background crashes and fix's battery drain. If you do NOT follow this then the device will have bad battery life, be

laggy

and crashes will occur regularly." Is that referring to step 6 flashing bootbackup.img? Or is that referring to step 7 flashing SuperSU again and wiping dalvik and cache? Because if I don't use boot2.img (per the link you gave) in step 6 instead of bootbackup.img, I can't get back into TWRP recovery. If it's talking about step 7, then I'm not sure why the phone would be laggy now...
[LG V20 Guides, News, & Discussion] AnUnseenHope:
Reflash boot2.img and then reflash SuperSU following all directions.
[LG V20 Guides, News, & Discussion] me2151:
the lag is from the debug bootimage(boot1 and boot 2). needs bootbackup(which is the stock one) or a different kernel. then supersu install.
[LG V20 Guides, News, & Discussion] AnUnseenHope:
True. Guess I should've said to install a new kernel instead of assume they were already going to do that. Thanks me2151 for all you do!

Hey me2151 I'm sure you have been asked and I did try the search bar first. However I did install the Konverged kernel in the post 2. But my Ls997 v20 still has static on boot up. Tried installing the LS997 stock OS again then the kernel still no luck. Once booted everything seems to work fine with the kernel. Also tried to stall Chaz187 Classic rom to see if the static on boot stops. It won't let me install rom says rom is for LS997 and that my device is a US996. Of course this is not the case the device is a SPRINT LS997. Any help would be greatly appreciated! Thanks James
[LG V20 Guides, News, & Discussion] me2151:
Unfortunatly the method DOES install files however if does not flash their proper headers so the partitions end up corrupt. So its a no go for now.

Use the latest twrp found on the forums for elsa devices.

EDIT: I have finally finished the zv8 stock rom. I am unable to upload it until i get home tonight though
[LG V20 Guides, News, & Discussion] shatteredhalo0:
I was afraid of this. If I flash bootbackup.img, then when I do adb reboot recovery, I can't get into TWRP in order to reinstall supersu. It just gives me static screen for a few minutes instead of going to TWRP and eventually the phone reboots normally to lock screen. It seems the only way I'm able to get into TWRP using adb reboot recovery is if I'm using boot2.img.
[LG V20 Guides, News, & Discussion] me2151:
What you need to do is flash the bootbackup then flash the twrp recovery. THEN pull your battery out to shut the phone off. unplug the phone. and then put the battery back in. Then Hold VOL- and POWER until you see LG then let go of ONLY POWER then hold them both again. You should get a screen asking to factory reset. select yes twice. you will then boot twrp with bootbackup. from there install supersu
[LG V20 Guides, News, & Discussion] shatteredhalo0:
When I get to the part where I hold VOL- and power, the LG screen comes up, then I release power and hold again and the LG screen continues to display for 3-5 more seconds, then the screen goes black, and the LG screen comes back, and this just continues until I pull the battery again.

Actually, I think I got it.. I had to release power AGAIN after the LG screen came back the second time, and hold it once again, then it booted into TWRP.

I am getting a failed to wipe dalvik now so hopefully that's OK.

Ok I was able to fix all my problems except of course the very finals step.

Verizon v20 rolled back to base software of vs99513a_04_1205_arb00

Of getting grey screens, boot loops,and system not mounted errors (and password inquiries) I finally made it to the very end.

Last challenge, tbe boss level. I'm confused what I'm doing is taking me in circles and what is actually a fix.

Earlier I've flashed boot 2 plenty of times by itself. Also TWRP and boot 1. That was before the ckean TWRP wipe with proper mounts.

What is flashing boot backup? Do I do that? I don't have that image file.

When did aboot come into play? Will it come into play? What do I need to do to get past this logo?

Can you get the device to Qualcomm loader mode? I'm very new to the V20 but came from the Nexus 6P which I bored my GPT. In QDL mode there are commands to rebuild GPT and send partition images to build partitions. So working with a good device could be possible to create all the partition images. Obviously the partition with the IMEI and other valuable info would be no good but somehow Qualcomm restores those values from inside the phone. I have the ATT model I probably couldn't help you. I was just reading thru about root and since no ATT kdz exists in the wild I won't root.

No edl mode. MY GPT was actually fine after much digging last night. I killed my DSP core. Dont know how it happened either. Not related to dirtysanta.

Samsung sucks.. and it is my professional official opinion that you should therefore stay with the v20 :D

---Updated: I found the issue. It's new root method (systemless) and also need compatible rooted app to work

My phone is VS995 and Security patch level is December 1, 2016. I followed the guide to install TWRP and root. TWRP is installed and works well but root seem not work.

I can use TWRP to flash SuperSU v2.82 successfully. After V20 reboot to system, there's SuperSU in app list and it can run. I checked root status by Root Checker app:

Device Status: Rooted

SU binary: Found su/bin/su

Build Tags: Not found contains "release-keys"

Executing su: Successful

BusyBox: Not installed

but when I run another apps (root explorer, Hide my root) which need root permission, these apps doesn't ask root permission and can not work. "Hide my root" apps tell that "Can not find the su binary".

When I flashed SuperSU, there's some fail log as following :

Boot image patcher
