What you need:

LG USB Drivers

Tec's LG DualMode Installation Guide

Specific KDZ Installation

Useful Links

These should help you reflash the firmware.

Then try to root your phone again from this page:

Root your LG Aristo 2/2+/K8+, remove encryption/verity & install TWRP and Magisk

[Miscellaneous Android Development] kittyinfinity666:
okay, I need some help I got the oem unlocked, flashed the necessary files got into TWRP recovery and found out my touchscreen no longer works. Now I cant approve the connection for adb to work so I cant use adb or fastboot it seems..... am I missing something or how do I fix this.... thanks
[Miscellaneous Android Development] NonStickAtom785:
Okay so this can be from one or two issues. Either your using an Aristo and accidentally flashed Aristo 2 stuff or the other way around. Or you've got an Aristo 2+ or K8+ that is very few in alot that are glitching from it.

Do you have TWRP installed and working? Or is it unresponsive to touch as well.

If you don't you need LG Up to reflash your firmware.
[Miscellaneous Android Development] kittyinfinity666:
Okay so the actual model of my phone is LM-X210MA and I have TWRP installed and can get to that screen but it also is unresponsive. I was going to try using adb to try and push the vendor keys and maybe re flash a different firmware.... Though I'm not too terribly sure if that will work or not.... Haha I guess I'll keep you updated on that, meantime any suggestions are totally appreciated
[Miscellaneous Android Development] NonStickAtom785:
You could try flashing the TWRP with the 10L kernel from here:

https://androidfilehost.com/?fid=11410963190603862817
[Miscellaneous Android Development] kittyinfinity666:
So I still haven't been able to access anything other than download mode (lg flash tool is what I have on PC) but where do I find the drivers for lm-x210g? What my device shows up as has changed since I messed up the first flash, and I can't find them anywhere. I think I am going to have to go back to stock before I can into TWRP as useable

*Update installing lg bridge hopefully I can update the software with that ~fingers crossed~ also on a side note.... Will the flashing I did that bricked it in the first place mess up my sim chip?
[Miscellaneous Android Development] NonStickAtom785:
Oh geze. :p

So do you have the Aristo 2.kdz?

If you don't here you go:

https://androidfilehost.com/?fid=11410963190603847051

I don't think the LG Flash Tool is gonna work download this instead:

http://downloads.codefi.re/autoprime/LG/Flash_Tools/LGUP/UPPERCUT_1.0.0.0.zip

And finally your drivers. There's been a lot of issues with them but try this:

http://tool.cdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425

Then After you have the drivers and everything set boot into download mode. Select the KDZ using Uppercut and flash it. It take around 20 minutes on a slower computer but 10 min on a quicker one.

Let me know if I helped in gettting your firmware back to original state. Then we can continue onward to flashing TWRP.

Leave a Thanks!
[Miscellaneous Android Development] kittyinfinity666:
:highfive: teamwork makes the dream work, I am downloading files now and will keep you updated, thanks soo much for helping
[Miscellaneous Android Development] kittyinfinity666:
Okay sorry I'm a little new at this but I keep getting the error about DLL not matching or something. I'll try to get a pic uploaded. But it says LAF protocol version is not match DLL and a string of numbers after
[Miscellaneous Android Development] NonStickAtom785:
What are you flashing it with? Uppercut only uses .kdz files the last time I checked, but all you have to do is restore your phone. I would give direct steps but I don't have direct access to a Windows PC. Check out tecknights lg aristo 2 tutorials. He has the full guide on how to restore using LG UP and stuff.
[Miscellaneous Android Development] kittyinfinity666:
OMG I'm getting network error cause I am on my phone network as I don't have home WiFi so I am having trouble uploading any pics .... anyways... So I am using LGUP_ver0.0.1.18.zip, uppercut1.0.0.0.zip, I also have downloaded LGH830_DLL.msi, LGH850_DLL.msi, and LGH850_DLL-V2.msi and still am getting an error message when I get uppercut running and my kdz file put in, check upgrade and start

Error: 0x81000302, please use latest DLL

LAF protocol version is not match DLL =95575216 DEVICE =98820128

So I am guessing I am missing something but I can't seem to find it.....

***Update**** sooo....I got the LGUP program to work but to no avail....still the touchscreen is unresponsive, it's also to high up so the problem must be with the twrp file I flashed though now I don't know how to go about removing it or replacing it as I have no ADB funtions cause I can't confirm anything even when I boot to recovery

.....

......
[Miscellaneous Android Development] NonStickAtom785:
Wait. Do you have TWRP installed and working? Or is it glitched out and raised to?

If anything you might have mismatched partitions that won't correspond with each other. If you have TWRP try installing Tec'sRootedAristo2v4 ROM from his thread. He has all the info on how to restore your phone properly.

Cant flash and cant root - adb reboot bootloader not working

Hello guys,

Im facing same problem that [MENTION=9587762]valerio.piccinini[/MENTION] ...

here is my status:

DEVELOPER MODE - OK

OEM UNLOCK - OK

DEBUG MODE OK

USB MODE tried every options.. from charging to midi - no success.

adb reboot bootloader just reboot device

adb reboot recovery, reboot device and brings me an screen with a little bot and under it is written "no command"

press vol down and connect usb cable, phone just starts in security mode

press vol up and connect usb cable, phone turns on in firmware update mode

I tried to disable developer options and enable again, and tried to get bootloader again but and no success...

One thing I believe that's important to say...

I'm in Brazil and here this phone is called LG k9 but I can't find anything about it like k9 root or k9 bootloader, then I went to settings and found model number LM-X210BMW then I google it and found this aristo 2 as same phone that here is LG k9 , so to be honest, actually I'm not completely sure if my phone is this aristo 2 phone...

I cant find any guide how to root LM-X210BMW or get the bootloader

any ideas?

thanks in advance.
[Miscellaneous Android Development] kittyinfinity666:
Yea twrp is also all glitched out... Techknight sent me a .img file to flash but I don't know how to flash it, at this moment the only thing I've been able to get to work is LGUP and that is for kdz files
[Miscellaneous Android Development] NonStickAtom785:
You can flash it by adb sideload... or if TWRP is working enough to install you can flash the .img
[Miscellaneous Android Development] kittyinfinity666:
Well I have no idea what I've done now but ADB isn't recognizing the device at all though my pc is but I am unable to access any kind of files for it or use the touch screen so it seems I'm going to need yet another work around, :eek: this kind of thing will drive a person mad
[Miscellaneous Android Development] NonStickAtom785:
I think it has to do with your drivers. They could be outdated or not the right kind. In my case I had to install Google Platform drivers manually to get adb to work. The R/W capability of your device could be encrypted by the system's OP folder. Did you try flashing a Rooted Version of the ROM, or reflashing a custom system.img?
[Miscellaneous Android Development] DeanDeanDean:
Stuck after reboot bootloader.

Thanks for your tutorial, but I'm getting stuck after step 4 in the Windows section. I have successfully put my phone in developer mode, turned on USB debugging, and enabled OEM unlock. I see the phone in "adb devices" and running "adb reboot bootloader" causes the phone to enter the black screen with the tiny text.

And this is where I'm stuck. Once my phone boots to the black screen with the tiny white text, it is no longer detected properly by Windows. Instead, it comes up in Device Manager as an unknown USB device called "Android" with the yellow error icon over it. Because the phone isn't recognized, fastboot can't detect it to unlock it.

* I've tried uninstalling and re-installing the latest LG USB drivers, v.4.2.0.

* I've tried using an older driver, v4.0.4.

* I've tried using various USB modes (MIDI, MTP, PTP, etc.).

* I've tried different USB ports, USB cords, and different PCs.

My phone is an LG Aritso 2, software version: X210MA10j, build: N2G47H, Android version: 7.1.2.

Anyone know what I'm doing wrong? Thanks!
[Miscellaneous Android Development] kittyinfinity666:
It was a rooted copy and a custom recovery. And I'll look into the drivers and update if they work.... I've got fastboot working now, and flashing new .img for recovery, do I need to flash a new ROM again as well since I used lg up to flash the stock .kdz file ???? What are the ramifications of... Say.... Hypothetically of course, just continuing to flash new roms/recoveries several times without any useable results? Also *update** I can no longer access TWRP mode... When I try to boot to recovery it's a black screen
[Miscellaneous Android Development] rogeliomalpa:
I have the very same phone as you and the very same problem. The only thing that works for me is flashing 10K KDZ and i'm able to recover touch and phone works again (Display's image is stable too). As soon as i flash TWRP, root_boot.img, or any other thing that is not 10K stock KDZ i lost touch and the image begins to glitch.

Behind the battery, in the info sticker i have

DATE: 10/2018 ***BAR CODE***

MODEL NO: LM-X210MA

FCC ID: ZNFX210MA

H/W: 1.0 S/W : V10K

S/N : XXXXXXXXXX

IMEI : XXXXXX-XX-XXXXX-X

**BAR CODE**

MADE IN CHINA

I was thinking that could be 2 versions of this phone, i think the one we have is a 2nd release and that's why it has V10K out from the box (Which is a recent software release for the Aristo 2). I've tried downgrading to no avail but as all versions are ARB 00+0 i can downgrade safely without bricking it, just that touch doesn't work and image keeps glitching and of course, i can't root:cyclops:.
[Miscellaneous Android Development] kittyinfinity666:
Well I havent actually gotten anywhere yet but someone is working with me on this with much more experience than me, hopefully he will be able to figure this misery out and I will post it as soon as we get it all worked out!
[Miscellaneous Android Development] NonStickAtom785:
Okay so both of you have the V10K version of the firmware. Interesting, as I have the V10J. As long as you don't have the V10L, the latest security patch you should be able to root. Kittyinfinity, you have TWRP installed correct? Both of you should upload your device boot.img's for me. I can manually patch them so you can install Magisk and achieve root.

What I don't understand is how you have the 10K firmware but it's not letting you install TWRP, or if I understand correctly, it's not allowing touch in either TWRP nor is it when you boot up. I'll try to remake the TWRP.img we already have, so that it might respond to touch. However I need your fstab.cv1 file for this.
[Miscellaneous Android Development] rogeliomalpa:
I have the V10K version of the phone because is the only one i can flash. If i flash, let's say V10C or V10H i lost touch functions and the image becomes glitchy. Doesn't matter if i flash root kernel, twrp or anything. If i go lower than V10K i will lose touch function and image will glitch. While i'm in V10K stock touch and everything works. As soon as i flash anything that is not stock the problem appears.

Behind the battery of the phone, in the info sticker i see it was released with V10K. I had another X210MA the last week and it said V10D and i was able to root that one. That's why i'm pretty sure there are 2 somewhat (hardware maybe?) different versions of the X210MA. While i'm in TWRP i lose touch so i can't make a backup.

Connected to the computer i can see it's ADB device being recognized in Device Manager but adb devices return it as unauthorized, i guess because i have to move the bar to the right to allow changes in TWRP, but once again, i can't because i don't have touch function.
[Miscellaneous Android Development] kittyinfinity666:
So, techknight has been trying to help me out with this issue as well and he asked for fastboot getvar all and flashing unlocked.... I dont know if it will help but I also sent this same info to him,

What you need to know about LG's Oreo firmware for the Aristo 2 and variants

TAT TecKnight's Aristo 2 Tutorials series

What you need to know about LG's Oreo firmware for the Aristo 2 and variants

If you update to stock v20c (Oreo firmware) using LGUP or OTA update, you will be unable to root your phone from Oreo. The Oreo firmware does still have the OEM unlock option under Developer options. You can also boot into bootloader mode and execute the fastboot flashing unlock command.

HOWEVER, fastboot will not flash any partitions under the Oreo firmware.

This begs the question, How can I update to Oreo and still have root ?

There is really only one way to do it. Use TWRP to flash a rooted Oreo image.

If you are already running stock Oreo, you will have to downgrade to Nougat based firmware (I recommend 10K or earlier), then flash TWRP from fastboot, then use TWRP to flash a rooted Oreo ROM.

Here is my tutorial for flashing my rooted Oreo ROM:

Install a custom pre-rooted ROM to your LG Aristo 2 or Aristo 2 plus using TWRP

Thanks to @jmanc3 for confirming that he was also unable to flash from fastboot under Oreo firmware
[Miscellaneous Android Development] Technically21:
Is it possible to root Aristo 2 Build X210MA20c With this method?
[Miscellaneous Android Development] tecknight:
Yes, but you will have to

1. downgrade to an X210MA10 build (Nougat)

2. Flash TWRP to your phone while in Nougat.

3. Flash my rooted X210MA20c ROM via TWRP.

Instructions are here:

Install a custom pre-rooted ROM to your LG Aristo 2 or Aristo 2 plus using TWRP

I Need HELP!

Hey guys

I was following a tutorial from LG ARISTO blog website on how to install the TWRP on my LG ARISTO 2 phone

But I can't get past the last step:

I installed the "Minimal adb and fastboot" and I typed "fastboot flash recovery recovery.img" and I get this-

"target reported max download size of 262144000 bytes

sending 'recovery' (16376 KB)...

OKAY [ 0.585s]

writing 'recovery'...

FAILED (remote: unknown command)

finished. total time: 0.595s

Can someone help me? Thanks in advance!
[Miscellaneous Android Development] tecknight:
Are you running an Oreo build (Software version v20c or later) ?

If so, you will need to downgrade to Nougat first.

Full instructions are here:

Install a custom pre-rooted ROM to your LG Aristo 2 or Aristo 2 plus using TWRP
[Miscellaneous Android Development] dphiljoe:
After obtaining root on lg aristo(the previous model...i think it was lg210) I've been unable to install system update to the phone and got stuck with the current android os at that time. Would it be the same for aristo 2?.

Are you able to download and install system update after root?

---------- Post added at 08:03 AM ---------- Previous post was at 07:54 AM ----------

I think i got the answer on this thread....a manual upgrade
[Miscellaneous Android Development] NonStickAtom785:
Yah. If your running the Oreo firmware while trying to root, you get trapped with stock recovery until you downgrade to Nougat. Nougat was root able so we installed TWRP recovery before the upgrade so we could flash the Oreo Rooted Firmware. Fortunately for us Nougat didn't have a locked up fastboot. They locked up Oreo pretty tightly so you can't flash with it bootloader.
[Miscellaneous Android Development] maqsur:
Related to the other thread (TechKnight's Tutorials); is the MetroPCS rooted Oreo rom working? Maybe just the A2P is not? I may try the MetroPCS variety soon. I can't get Nougat to root, either. I dunno!?
[Miscellaneous Android Development] qwazy2:
Hi tecknight, thank you very much! I followed your tutorials to root my Aristo 2 and everything went smoothly. I had no problems during the process.

Again, Thank you! ;)
[Miscellaneous Android Development] NonStickAtom785:
Let us know if there is anything wrong with the ROM and if there is anything that isn't working right, such as substratum, or fast charging. Stuff like that. That will help in the development of further ROM's.
[Miscellaneous Android Development] maqsur:
Substratum hasn't worked for me on the rooted Oreo rom. Also tried with Andromeda and still no dice.

[Miscellaneous Android Development] CosmicDebri:
I still cannot get past 2nd step

I have ab LG Aristo2 that was upgraded to Oreo. I downgraded to Nougat as suggested by tecknight as I am following his tutorial. I can get the phone to boot into fastboot, but after that adb or my win 10 computer won't recognize the phone anymore, so I can't continue. It just sits there saying "Waiting for devices." I have installed the mobile drivers, more than once to make sure, installed LG Bridge and LDUP as well. I cannot fathom why it will not go past the fastboot screen. Please help whoever can cuz I am ready to throw this thing into the forest.
[Miscellaneous Android Development] eheinzeiii:
hey i did this successfully and the hotspot does not work, is there a fix for this? thank you very much for this man, very good job.

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

i had this problem as well, i ended up using a linux machine to use fastboot. i would like to see if you get it working tho.
[Miscellaneous Android Development] CosmicDebri:
Great. I USED to have a dual boot machine, Win 10/Mint Linux. I was trying to survive on Linux and not use Windows unless I had to. Alas I was into gaming at that time, and too many didn't have linux versions, and when I got my newest computer I just did a fresh Win 10 install. I might be able to dig up a Live Mint disc and maybe can do it with that. Thanks for the heads up.
[Miscellaneous Android Development] CosmicDebri:
Got it!

Well, I got mine to work finally. I tried booting a live linux mint but it wouldn't let me use root to install adb. So I tried on my Lenovo laptop instead of my desktop. It has Win10 on it like my desktop, but it hasn't been updated in about 6 months or so. I installed the LG mobile drivers, the adb suite and assorted images and whatnot.

I hooked up the phone and ran the adb reboot bootloader command. It did that. When I did that I heard the windows sound of a usb being disconnected, then the sound of it reconnecting. All of which happened on my desktop. But then a window popped up saying readying Android device. That never happened before. I waited what seemed like a few minutes, nothing else happened. Then I did a fastboot oem unlock command and I got the waiting for device line, and it just sat there. I was bummed thinking it had failed again. But I apparently didn't wait long enough because it then had a few lines show up in the adb window, and a window popped up saying Android setup complete. I was then able to do the rest just fine.

So it seems the issue is between the drivers and the latest updates to Windows 10, or it just didn't like my Inspiron 5675 desktop. So if your having the same issue, I would try a different computer as long as it's not fully updated, or maybe even a Windows 7 or a linux box if ya got one.

I'm just kinda confused right now, even though I gave AppMgr III SU privileges, I still can't delete any of the Metro apps on the damn thing.......
[Miscellaneous Android Development] NonStickAtom785:
Hey you wouldn't mind helping develop would you? I noticed you said you have linux mint. Me and my friend are having trouble getting the kernel to compile.
[Miscellaneous Android Development] CosmicDebri:
I wouldn't mind developing, however I don't have Mint installed. I was trying to use a Live CD which just lets you put the disk in your system and reboot into it off the cd. But it's too limited that way, doesn't allow root or saving or anything good.
[Miscellaneous Android Development] NonStickAtom785:
Do you have Windows 10? The latest version has a Linux Subsystem that you can enable from the Programs and Features. Just enable that and download Ubuntu 18.04 from the Windows Store.

Changing the boot animation

I found a way to change the boot animation. Just remove it from /OP/MPCS_US, and then there's a symlink for it somewhere else. I forgot the location. I removed that Symlink, and then applied my boot animation manually by overwriting the bootanimation.zip in /system/media.

I don't remember the exact folder. When I have time I can investigate further and try and find the symlink. :)

---------- Post added at 03:06 PM ---------- Previous post was at 02:58 PM ----------

Yes. If you use Magisk, and install snapchat before installing any modules, then it works.

Remember that installing Xposed will cause snapchat to not work. So before you install Xposed, install snap, and any other apps that use SafetyNet and get those set up before installing Xposed.

[Miscellaneous Android Development] firekiddie:
It would probably be easier for you to use LG Bridge's recovery tool.

What you're gonna do is power off the device in question. Then you're gonna go to LG's website and install LG Bridge, and LG Universal Drivers. Follow the installers.

Reboot your PC,

Then you're gonna connect one end of a USB cable into the phone, and press VOL Down, and connect it to the computer at the same time. You'll see a little dialog saying "Download mode" (I can't attach attachments to my posts, sorry.), and then something saying "Firmware Update."

What you're gonna do is open LG Bridge, go to Software Update, click "

Update error recovery"

Then just follow the flow of instructions from there.

When you're done, you're gonna want to follow the instructions for O to downgrade to N to root.
