Ok thanks you. Using kernel from this thread, my video recording is broken, static picture only sound. But after using DOTS kernel, it's solve the problem.

Sorry, i want ask one more thing. If i want flash to stock rom, is it necessary to copy abootbackup first or directly use LGUP to flash stok rom ?
[LG V20 Guides, News, & Discussion] rachentp:
AME

If anyone has these files, I would greatly appreciate it. I could even pay for it if necessary. I have the H990DS AME version. The first time I tried root I think it didn't work because I used the TWN firmware. I'm looking for the AME one before 2017. And then the most recent kdz to update it after root. Thanks.
[LG V20 Guides, News, & Discussion] hotcell:
You'll need 10d version for root.

After that I had 10g version. The current I'm using is version 10h.

Note: The link names contain month and year [formatted as MMYY] ids, so you'll see the 10d is from Dec 2016, 10h is from Jan 2018 - don't let to mislead yourself and take the number 0117 as LG (un)intended typo:highfive:

[MENTION=1057334]hotcell[/MENTION] I could kiss you right now :victory:

Can I skip right to h after d? Or do I need g inbetween?
[LG V20 Guides, News, & Discussion] hotcell:
Glad you could get the root, enjoy it!

I have not tried to skip directly from d to h. I'd guess you can try. If it wont work, just download 10g.

And remember to share your findings here!
[LG V20 Guides, News, & Discussion] rachentp:
I just wanted to report that the root went flawlessly. So thank you again [MENTION=1057334]hotcell[/MENTION] for the right files. I know now that it was using the wrong firmware (TWN instead of AME) that I failed before. Thank you again everyone for all your help!:victory:
[LG V20 Guides, News, & Discussion] hotcell:
So AME 10d straight to 10h went fine?
[LG V20 Guides, News, & Discussion] rachentp:
Yes. I used the kdzwriter tool and d to h was fine. No need for g though I did download it just in case. Now I'm just having a little trouble with Xposed. First time I messed around with it I got a "system ui is not responding" or something like that and had to do a factory reset. Which has now made me paranoid moving forward. So starting over again but then none of the modules would work. So I uninstalled Xposed and am waiting for the phone to boot to reinstall. -_-
[LG V20 Guides, News, & Discussion] hotcell:
It's good to know 10d to 10h is working, thanks!

Can't help you with Xposed, I'm trying to avoid the thing so far.
[LG V20 Guides, News, & Discussion] rachentp:
I'm just so happy I got everything to work. Like, so happy I could cry. I've been with LG for a long time and have always had root. So when it didn't work out the first time I was so disheartened. Every since you gave me the files, I have been so ecstatic. JUMPING UP AND DOWN WITH JOY!! Thanks again, [MENTION=1057334]hotcell[/MENTION] :D

Hopefully I can return the favor someday.
[LG V20 Guides, News, & Discussion] hotcell:
Yeah, I just pointed you to the right file links as I have the same variant. Glad I could help.
[LG V20 Guides, News, & Discussion] sptw:
Xposed not work for me too. Tried all versions and none of them seems to be working. In my case, the phone got a bootlooper, so i need to use a zip file and twrp to uninstall.

I give up xposed too.

So I tried to root my h990DS with the method described in the first post and evreything seemed to work fine. But after step 16 when i executed "fastboot reboot", the device rebooted but there were strange stripes on my display so I couldn't read anything (after the first lg logo just looked normal), so it began when loading the os. The sound played just fine....

When I try to boot to recovery the "Reset Data" Dialog looks completly fine as always but then there are this graphical glitches again when it should enter TWRP, it also seems to just delete the data and then reboot normaly...

When it is booted (or not, I cant see what it does), the screen goes black and i try to wake it up there appears a Kernal Crash messsage

When connected to the pc there is only "LGE AndroidNet USB Serial Port (COM 14)", also with fastboot (vol Up + usb cable)

What can I do now?

(I cant post links yet)

//Edit

Ok after posting this I found a solution by myself:

If found USB Drivers for the device shown, and after I installed them LGUP was able to detect my phone again and i could refurbish to the system i was before trying to root

Driver: http://mirror2.helpjet.net/LINK-VAL...itedMobileDriver_S497CA20_WHQL_ML_Ver_1.0.msi

No I will try to root again

//Edit 2

After doing the steps again with the drivers now installed and another usb-c cable used i get to the same point as last time

The system I used should be correct (security patch from december something 2016)

What could I do wrong?

//Edit 3

Found my misstake eventually, executing "fastboot reboot" caused the problems with my device. So just skipping that and taking out the battery did the trick.

Now I seem to be stuck with the version I use, since TWRP prompts for a password all the time no matter how often I do "format data" or "wipe"...
[LG V20 Guides, News, & Discussion] zeguym:
Hi, i want to ask about returning to stock room.

Is it really necessary to flash back abootbackup?

What happen if i flash using LGUP with out flash abootbackup first?

I ask this because i don't know is the abootbackup is the correct one. When i root, i have to try several time, and stuck at step 2 (when backup abootbackup).

[LG V20 Guides, News, & Discussion] Phoenix591:
Did you actually root with Magisk or SuperSU? If not then everytime the system boots it'll reencrypt /data. Regardless if you switch to my twrp it should be able to get decrypt just fine (it'll only actually ask for a password if you set require pin/password/pattern at startup). You can install it using twrp itself by (if you don't have an sdcard you can push it with and a PC) going to install>install image (browse to where saved and tap it) recovery>swipe, alternatively an app like flashify will work if you have root.
[LG V20 Guides, News, & Discussion] Incredible_Max:
I rooted it Magisk and installed the Kernel in following order:

System Wipe

Format Data

In 1 Zip install queue:

-Install Kernel

-Install Magisk

Device seems to be rooted fine (checked with RootChecker App) but TWRP just wont let me in, I did set a pin but when the os prompted me i chose not to use it for startup, and the pin also does not work for twrp, neither do Google Password or 'default_password'
[LG V20 Guides, News, & Discussion] Phoenix591:
The old twrp which the thread has you install has broken decrypt and so won't work (not sure why if rooted format data and typing yes isn't clearing the encryption then), but my twrp builds do handle encryption just fine
[LG V20 Guides, News, & Discussion] Incredible_Max:
Ok so what do I have to do then to get that encyrption away?

And why hasn't the original post not been edited?

Found the TWRP you mentioned and installed it from the twrp which was on my phone (twrp->install->install img). Rebooted to system, then to recovery and evreything seems fine now

I have a problem !!!

I have a V20 device H990 with nothing after that

With 10B rom with a security level of 11 \ 2016

I want to do a root to the device that I return from the custom rom Super V20

But after I installed the rom of lg i can not seem to do a root because i get the error in step 8

Type "run-as con" <-- If you get unknown package error, means your latest security patch patched it out; go back to step 3. LGUP should be able to downgrade you to an earlier firmware update.

Although my rom is the lowest there is today 10B as I wrote earlier

i Need Help

That's what I tried

I'm running USB debugging

I am running an OEM opening

I tried different cables

I tried different USB

I tried 3 different computers

Yes i have access to device in usb i can send files and get them

Yes I have approved ADB

What have I tried already

Install a different rum which is also 10B

Upgrade to a new version and lower back both through the device and through LGUP

Reset device several times

I am open to Suggestions

Hey guys the earliest stock rom that i can find for my H990TR is 2017-01-23 10e rom, is it impossible for me to root this phone after all?
[LG V20 Guides, News, & Discussion] Redline:
Try the V10c TWN region KDZ file. It should work fine for your phone to get setup and rooted at the start. Then you can use KDZ Writer to update to latest KDZ for your region and keep root.
[LG V20 Guides, News, & Discussion] hotcell:
What matters is the date of the security patch. What is kdz file timestamp is irrelevant. What is full name of the kdz file?
[LG V20 Guides, News, & Discussion] MuradinB:
It's H990TR10e_00_OPEN_TR_OP_0110.kdz and 2.63gb file size.

didn't know that was possible
[LG V20 Guides, News, & Discussion] hotcell:
Looks like ROM dated as 10th of January 2017. If the year 2017 security patch is already applied, you won't be able to use DirtySanta exploit with this version. But, I don't know that for sure, so I'd guess you can try to root or use the other user's suggestion to get the root. The key is to make backups as described so you'll have a chance to roll back.

Worked great on H990DS, followed the instructions and got it unlocked and rooted in no time. This may seem difficult at first but in real its simple step by step process. Great work by emdroidle and whosoever involved in the process to unlock this device. Simply without unlock there is no fun using any android device. Thank you very much emdroidle, its just because of your efforts I will be using this device otherwise I would have sold it like the LG G5 the very next day. Great work, thanks again :D.

Hi Everyone!

I have a LG V20 H990DS running firmware V10-f-IND-xx. I am planning to root and i decided to go through this thread for tips. Most people here from my region, who rooted their phones seems to be facing issues with Volte after rooting. Anyone here can clarify if the issue can be fixed and also which firmware should i download for my BACKUP Plan as i could not find the firmware for my region online.

Also, does ViPER4ANDROID works with this model after root?

TIA :)
[LG V20 Guides, News, & Discussion] Redline:
You can get firmware KDZ to flash from here (this has IND region firmware): https://lg-firmwares.com/lg-h990ds-firmwares/

If you have issues with VoLTE after rooting (maybe it is not enabled in the region of firmware you downloaded from (TWN, AUS, etc.) ) then you can use KDZ Writer in the thread for it to flash /modem part of firmware from other region KDZ that has VoLTE enabled (also update /system, etc. as explained in its thread).

I recommend TWN version firmware as your backup, as that seems to work in the most regions (I know with this region you need your phone to be on v10c-TWN firmware to use DirtySanta root method) and seems to be the most kept up to date, as well as has the smallest bloat apps to uninstall after setup (I use Root Uninstaller Pro to do this). As for Viper4Android I am not sure if it works or not but if you search for its thread in these V20 forums you should be able to find it.

Work is being done in the LineageOS 15.1 thread for H990DS. Soon hopefully.

Not sure which version for IND region but you can use V10c-TWN region KDZ to flash and root.

So I bought a 2nd hand LG V20 H990DS TWN today and the guy didn't mention anything about root.

When I try to boot the phone it says "Your device is corrupted and cannot be trusted" after that It boots normally, but I can't get super su to work, so it does not seem rooted.

I do however can get it to boot in TWRP, I only have no idea which steps he has taken already, and which other steps I need to do in order to get root. Anyone can help?
[LG V20 Guides, News, & Discussion] orlandofc:
I want to do root, but after everything is ok, in the subsequent boots all will have this red triangle with a warning message? I would later decide to sell the cell phone not having this warning .. is it possible?
[LG V20 Guides, News, & Discussion] faeterov:
Yes, you can revert to stock by flashing a stock kdz with lgup, and everything will go back to normal.
[LG V20 Guides, News, & Discussion] faeterov:
So he unlocked the bootloader with dirtysanta. To check if root is enable, use any of the store apps that check root.

Maybe he is using magisk, and that doesnt enable you to install super su.

If neither magisk nor supersu is present, then trought twrp you should be able to install any of them.
[LG V20 Guides, News, & Discussion] fedort:
Thanks, unfortunately neither supersu or magisk is present/working yet.

But I'm able to get into TWRP, does that mean all other previous steps have been taken succesfully?

So the only thing I have to do now is flash "h990-kernel.zip" and then flash SU implementation (Magisk.zip or SuperSU.zip)?
[LG V20 Guides, News, & Discussion] faeterov:
If you have twrp installed and you are able to boot to the os, then al thats remaining is to inplement root like youve said

Thnx!
[LG V20 Guides, News, & Discussion] Electrolite_XYZ:
Ok this was kinda nightmare inducing. Had some problems like LGUP not detecting my device etc but managed to overcome all problems.

The worse part when I was in TWRP and would install Magisk and somehow it was corrupted, I removed the SD card reinstall Magisk and reboot to recovery again using TWRP and it worked but I got to say my heart froze.

Also the first time I tried I was locked in the secure boot so I went back to TWRP and wiped the cache and data and installed the kernel and Magisk again.

Anyway everything is working fine, all issues I had were not really related to the ROOT method so I think it's working well. Thanks for this now time to install Viper EQ and all the other sweet stuff.

Help!

I attempted to root my h990ds with the dirtysanta method, and took great care to follow the instructions to the dot. After the fastboot step, I entered download mode and when it was supposed to reboot into twrp, the phone just displayed static on the screen. After trying multiple times (booting into twrp as well as standard boot, just for the heck of it), and getting the same strange static, the kernel crashed. The device refuses to do anything other than go to static after the LG logo. Any help would be greatly appreciated. Thank you.

No luck for H990 South Africa

Unfortunately no luck for me.

Using a H990 from South Africa, hopefully someone else with the same phone and model can get something from this.

I saw someone posted in the comments and they didn't do the fastboot reboot, I followed steps to the tee. After the fastboot reboot I just get static all over my screen. Luckily I've loaded a new ROM via LGUP enough times to know what to do.

I'll probably try to just pull the battery tonight according to that post which might do the trick. But all in all loading the ROM for pre-November 2016 security patch removes service provider bloatware which was nice.

Added* I've also tried to contact LG to try and find out if they would release the unlock key for the bootloader but no luck.

---------- Post added at 02:12 PM ---------- Previous post was at 02:05 PM ----------

Hey Man

Try taking out the battery and put it back in. Then while the phone is off have have your usb connected with your computer. Then as you plug the USB into your phone press the volume up button. This will take your phone into a downloading option. If you saw static from where it was you'll probably still see static here but you can at least recover your phone. Download a previous kdz file from your region for your phone then use LGUP to "upgrade" your device with that KDZ file. That should solve the trick.
[LG V20 Guides, News, & Discussion] jl10101:
I fellow South African! Ha!

Can you get into TWRP? (Pull the battery, then volume down and power, quick release power and press again on LG logo, yes to both questions.)

Flash DOTS kernel and see if that solves the problem?
[LG V20 Guides, News, & Discussion] Henry8th:

TWRP

Okay well I managed to get TWRP loading. When I install the kernel and supersu I after the reboot it asks me for a secure password for user data which I don't have. So I tried formatting from within TWRP and clearing the data then reinstalling the kernel and supersu but no luck unfortunately. Will keep on looking how to bypass that secure password.
[LG V20 Guides, News, & Discussion] cnjax:
Did you actually use format data where you have to type yes or did you just wipe data?
[LG V20 Guides, News, & Discussion] Henry8th:
Thanks

Hey

Thanks for the response. First time round I didn't do that, tried to boot and it got stuck at LG logo screen, probably for 10 minutes. Maybe I'm to impatient.

Second and 3rd time I actually used that option where I needed to type yes. Did that, then installed the h990 kernel and supersu. After that it happened again where it's stuck on the LG logo screen after reboot.

Not sure if I should/can load a kdz from TWRP as well? After I've loaded the kernel.
[LG V20 Guides, News, & Discussion] cnjax:
Maybe your not waiting long enough for the first boot it can take about 15 to 20 minutes to get to the welcome screen
[LG V20 Guides, News, & Discussion] Henry8th:
Found the problem

Thanks for this response, helped me a lot in my trouble shooting process. I knew I might be doing something wrong since this should work. So what I did after I've formatted in TWRP, I deleted all the data as well, but I deleted the system data too. Once I excluded that folder and installed the kernel and supersu everything worked. Booted up now and configuring my phone.

Thanks all for the input and help on this.
[LG V20 Guides, News, & Discussion] Redline:
I recommend updating to the latest Kdz for your variant using KDZ Writer (this allows you to update your stock system while keeping root) and then switching from SuperSU to Magisk, and installing the D.O.T.S 1.5 kernel.

Then maybe perhaps consider joining us in the newly available LineageOS 15.1 for the H990/DS :D

Glad you got setup and working!

Downgrading to a root vulnerable KDZ is just because LG managed to patch the exploit in newer KDZs. So once it's been rooted, KDZ Writer can update parts of the system and leave root intact (the exploitable part) I'm on the latest KDZ for the H990 and have root running without hassle.
