Do you currently have TWRP installed ?
What firmware are you running currently ?
I have TWRP 3.2.3.0 installed I am pretty sure. I will check when I get back home in a few hours. I am running an Oreo Rom made by the user/Dev nonstickatom. I am not sure how it would differ but I can help in anyway possible. Just send me a link with instructions on how you want me to test it and I'd be more than glad. Thanks

Thanks. One item I could use is a copy of your OP partition.
I has some provider specific files and it is used to map certain configuration items. It does not contain any user specific or sensitive data--Any one with your phone model and carrier should have identical OP folders.
If you don't mind a typing a shell command for me, it should be easy to pull the image.
Here's how you do it:
1. Boot into TWRP.
2. Select Advanced->Terminal. You will now be at a root shell prompt.
3. type:
dd if=/dev/block/bootdevice/by-name/OP of=/sdcard/Download/OP.img
4. dd should create a file named OP.img in your Download folder. It will be very quick, likely less than 5 seconds.
5. Upload the file somewhere online (Google drive possibly) and send me a link to the file. You can post it or PM the link to me if you like.
Thanks. I actually have the ROM ready for testing, but I want to see your OP image first, just in case there is a surprise in there.

it seemed to dump a bigger file running the command from adb shell with su privilege

can you help me with this, i did it all and my screen wont work i cant swipe or anything
I have actually created a procedure and 2 installers for this:
TAT TecKnight's Aristo 2 Tutorials series
Restore your Aristo 2 / 2 + Images/Animations & Carrier Software to stock
Requirements:
  • An LG Aristo 2 or Aristo 2 plus with TWRP installed
Note: This procedure will restore the OP and carrier partitions on your phone to stock. This will have the effect of restoring all bootup and shutdown screens and animations to stock for your phone. It will also restore the stock carrier software (T-Mobile or Metro PCS). As these partitions never get updated when flashing from a .KDZ file, this may be the only way to restore these partitions

1. Download one of the following TWRP installers. Either download the file directly to your phone or download it to a PC and copy it to the phone.
OR
2. Boot your phone into TWRP. Once in TWRP, select INSTALL then browse to and select the installer downloaded in step 1.
3. The installer will flash the OP and carrier partitions to a stock image. Select REBOOT SYSTEM

Please hit the Thanks button at the bottom of this post if you appreciate my work.

_________
Change Log:
06/03/2019 Created initial procedure.

Missing Touchscreen Driver on LG G8

Hello

---
Background
---
I have an LG K8 that I recently purchased, and decided to root. My phone was manufactured 01/2019, and has for its Model Number "LM-X210ULMG". The box advertises this phone as an unlocked (carrier) smartphone. I have read the following guide written by brad2192, and revised by parcek (Titled "lg-aristo-2-root-t3746425": Further Updated for Rooting Noobs: 10 Steps), and decided to follow through using this as a reference.

As I use Ubuntu, I was able to successfully install the appropriate packages for platform tools ADB and FASTBOOT, and connect with my phone. I acquired Magisk 16.0, and newtwrp.img, but unfortunately root_boot.img in the first post of the guide returned a 404 not found error. Later on though, I acquired root_boot.img through another link further in the thread (From Android File Host, with File ID 673956719939818308)

I then rebooted the phone into its bootloader, and flashed the boot partition with root_boot.img found in the guide. The flash was successful, so I decided to test the phone out by rebooting without flashing recovery. However, upon the entering Android setup workflow, I noticed the touchscreen did not work. The phone did not register any touch presses, but would register volume up, down, and power.

---
Questions
---
a. Has anyone tested this particular model of phone with rooting?
b. Has anyone else had touchscreen issues where they were not able to use the phone unless they restored from an earlier backup?

---
Troubleshooting Steps Taken
---
- Rebooting the phone does not work
- I've acquired LG Bridge, which is able to recognize that a device is connected, but after perhaps 20 seconds or so, LG Bridge gives up and says "Unable to detect the handset" or some similar message.
- LG UP does not recognize the device at all
- I have tried re-flashing root_boot.img to boot to see if perhaps the flashing process was botched. The touch screen still did not work. Interestingly, adjusting orientation causes artifacts where the screen is offset from the bottom by perhaps 80 to 100 pixels or so, and the screen appears to be interleaved, before more orientation adjustments cause it to go blank (backlit but all black pixels).
- I have flashed newtwrp.img to the phone, but am not able to boot into recovery using "fastboot reboot-recovery". Not sure if I have correct syntax there.

Other notes:

- For fastboot to recognize the device when in the bootloader, the USB cable **must** be plugged in to the computer first, then inserted into the phone with the volume down button held to enter fastboot mode.
- Only fastboot commands work. This is probably why it is called fastboot.
- Download mode can be launched when the USB cable is plugged into the phone with the volume up held
-- Neither LG UP, LG Bridge, adb, or fastboot recognize the device at any point in this mode

Updated Notes:

- Acquired LG UP Developer edition per Techknight's "Install LGUP Dual Mode(Dev/User) on your Windows PC". This was able to detect the com port over USB for the phone. Am now able to flash KDZ images. Going to try something close to my model, as I have not found the exact stock model image to restore to.

More Updates:

- Failed hard. Overwrote boot partition with latest TWRP recovery (TWRP with 10L kernel). Then, wrote this same image to recovery partition. Was able to reboot into Downloader mode okay (that still worked). Decided to try booting into Recovery and "adb sideload 'TecsAristo2pv2.zip'" which the command completed successfully. Then rebooted. Then bad things happened.

Now the device does not boot at all into either recovery, or fastboot. But if plugged in via USB, this device does show up as "Qualcomm HS-USB QDLoader 9008".

lol.

Welp. I'm gonna try this guide out later. "[GUIDE] Fixing hard bricks [Qualcomm HS-USB QDLoader 9008]" If anyone has any suggestions, I would love to hear them.

I'm having this exact same problem, did exactly the same thing, flashed the root boot.img to my LM-X210ULMG and now my touchscreen does not work. Can anyone help out with a way to fix this problem?

Looking for hope

I'm having this exact same problem, did exactly the same thing, flashed the root boot.img to my LM-X210ULMG and now my touchscreen does not work. Can anyone help out with a way to fix this problem?
I have the LG K8+ (2018) LM-X210ULM for U.S. Cellular and am hoping to get TWRP and a ROM with equal functionality as the stock ROM but without the bloatware. I am eager to try this out however this is currently my only phone and from what I've heard, the touch screen doesn't work after flashing root_boot.img. I have a little amount of experience flashing recoveries since I flashed my Amazon Fire 7, 8, and TV Stick. If someone can point me in the right direction to bring my LG K8+ to fill glory. I am trying not to brick it in the process.
Another question I have is does the cellular connection work the same on the LineageOS ROM? Or better? How about data? 4G? 2G? NoG?
I like to have a good idea if what the outcome will look and feel like before I start messing around with the phone.

Yes i can help you. You should buy special cable like this one https://www.amazon.de/UGREEN-Kabel-...sc=1?source=ps-sl-shoppingads-lpcontext&psc=1

Then :

First step: Make backup all your phone with LGUP then.

1. Put in your phone and put in bigger one entry mouse from PC - You will be able to control the phone

2. Go to settings and choice facetory reset

3. After reset you will go to Recovery TWRP , connect your phone to PC and upload file https://androidfilehost.com/?fid=11410963190603906259 on your phone.

4. Now connect your mouse to phone and with TWRP make flash this file AR.Oreo.Rooted.v6.zip ( It's working with LM-X210ULMG )

5. Reboot and now your Phone will work fine with touch.

Ok so what is the easiest way to root my LG Aristo 2 K8 from Metro PCS? I am stuck on step 9 on another forum post and wonder if there is a way to root my phone without all the extra work. My ADHD is really messing with me.
