[Recovery] Twrp v3 for Lg Aristo [metropc/t-mobile]


The stock boot image has dm-verity, which prevents you from booting if you swipe to enable system modifications after flashing twrp!


Flash a root such as SuperSU or phh-superuser. You should also flash no-verity-opt-encrypt.zip.

Prerequisites :

Enable OEM Unlocking and usb debugging in developer options!


- reboot into fastboot [ adb reboot bootloader ]
- fastboot oem unlock [ this is going to wipe your data ]

If you have problems with the device drivers installed , you will need to install lg bridge app from lg that contains the device driver

How to flash the recovery:
With your phone off, connect your usb cable to your phone while holding VOLUME DOWN to boot into fastboot mode or just type [adb reboot bootloader] in the adb terminal

Open a command prompt and type "fastboot flash recovery <path_to_recovery.img>” without the quotation marks.

Example: fastboot flash recovery C:/Users/John/Desktop/recovery.img

[don't forget to extract the downloaded recovery zip to get the recovery.img]

WHEN THE FLASH COMPLETES: (Takes about 2 seconds)
On your phone, unplug the usb cable and power it off by taking out the battery and putting it back in.

HOLD VOLUME DOWN + POWER until you see the LG logo and then temporarily release the POWER button, immediately pressing and holding it back down until you see the white prompt [factory reset] screen. You will NEVER release the volume down button in this process!
Use the hard keys to select "YES" and then "YES" again to boot into TWRP!

How to Disable encryption & flash super su
1. In TWRP, go to Wipe > Format Data. Enter the keyword ‘yes‘, in the provided space and enter. This will wipe the automatically encrypted filesystem, and decrypt it.
2. Once the wiping is done, reboot back into recovery. Go to Reboot > Recovery.
3. When the recovery boots again, connect your phone to the PC and Enable MTP under the Mount section.
4. Transfer the downloaded ‘no-verity-opt-encrypt-2.1.zip’ and ‘SR1-SuperSU-v2.78-SR1-20160915123031.zip to your internal storage or EXTSD
5. Disconnect the device now.
6. Tap on Install. Now, navigate your phone’s storage and select ‘no-verity-opt-encrypt-2.1.zip’. Finally swipe the ‘Swipe to confirm Flash’ button on the bottom of the screen.
7. The flashing process will merely take a few seconds. And when it’s done, follow the same method to flash the root package – SR1-SuperSU-v2.78-SR1-20160915123031.zip
Wait 1 or 2 minutes after the zip files are done flashing then reboot system and PROFIT! Your phone may take 3-5 minutes to boot the first time and it might boot-loop once or twice at the Metro PCS splash screen but don’t worry this is expected.

All required files [supersu+dm-verify disable] can be found in this thread :

well, I was able to flash the recovery after several failed attempts, however - I may have flashed over my boot partition to do so.

Ignoring the problems I was having that led to my decision to do this, I now have working TWRP recovery!

But, if anyone could upload their stock boot.img (for MetroPCS Aristo) then I can get back to using this for anything other than recovery - I'd be ever so thankful! :p

If it helps, I have fastboot, adb, and twrp access. Unlocked bootloader. Just need to flash my boot partition w/stock again. Waiting on KDZ download if I can extract it from there before anyone uploads a boot.img I'll post it myself (for anyone else that has a lapse of judgement).

did you get KDZ download to download I have this file if you need it
#3 Nextel69, Feb 7, 2017
Okay, so I'm kinda running out of ideas. So, I'm thinking of doing something drastic. If I delete the system with the fastboot commands, will be able to boot in TWRP the manual way?
#4 LG Fanatic, Feb 7, 2017
no don't go crazy with your device or you will break it.
#5 messi2050, Feb 7, 2017
Okay, so I made some progress.:D I reflashed TWRP and used the format userdata and cache fastboot commands and I am now able to boot into TWRP. Once there, I restored the backup I made, cleared cache again and I no longer see the "Encryption unsuccessful" screen. My new issue is the phone gets stuck at the LG boot screen. Maybe, I'll need to flash the stock boot image? I'll try a few things and report back.

Sounds like ill wait until all thr bugs are worked out. Awesone job finding root process tho. For sone reason I cant make my external sd card work as a internal storage..
#7 MrMadMike, Feb 7, 2017
It works fine, I just made one boneheaded mistake.:p
#8 LG Fanatic, Feb 7, 2017 Last edited: Feb 7, 2017
Guide updated with more detailed instructions
#9 messi2050, Feb 7, 2017
Is it possible to flash the "no-verity-opt-encrypt-2.1.zip" with fastboot commands? I think not flashing that is what is preventing my phone from booting properly.
#10 LG Fanatic, Feb 7, 2017
Okay, I can flash zip files through fastboot but, it's failing because of the partition's unlocked status. I'll try a few more things. This has been quite the learning experience. Next time, I'll follow instructions more closely next time.:p

So, I earlier this morning I was finally able to fix my Aristo. I had to use LGUP tool to flash the stock firmware on my phone. I made another mistake when reinstalling TWRP by not formatting the data in the "Wipe" area if TWRP. That put me back into the "Encryption Unsuccessful" error screen. However, this time even reflashing the stock firmware didn't fix that error screen. What did was reflash the TWRP image file, format both the userdata and cache with fastboot commands. With that, I'm back in TWRP and I followed your steps to the letter this time and now have a fully functional, rooted and TWRP'ed LG Aristo.:D

In a weird way, I'm kind of glad this happened. I feel like I've learned quite a bit about fastboot, fixing errors like this and increased my google-fu skills.:D

question regarding this part

3. When the recovery boots again, connect your phone to the PC and Enable MTP under the Mount section.
4. Transfer the downloaded ‘no-verity-opt-encrypt-2.1.zip’ and ‘SR1-SuperSU-v2.78-SR1-20160915123031.zip to your internal storage or EXTSD

where do i navigate to because my phones folder isn't showing up under this pc like it used to
#13 WNDRazoR, Feb 8, 2017
I'm happy that it's finally working for you , i hope this gives you and the others an idea on how difficult this work specially when you don't have the device to test on it ;)
#14 messi2050, Feb 8, 2017
Did you tap the "Enable MTP" option? The phone should show up after that.
#15 LG Fanatic, Feb 8, 2017
It really does. You guys absolutely rock!:D
#16 LG Fanatic, Feb 8, 2017
i did and it didnt :(
#17 WNDRazoR, Feb 8, 2017
Check the device manager to see if the drivers are installed correctly.
#18 messi2050, Feb 8, 2017
also, i have unlocked the bootloader but when i try to download a reboot app from the play store it says root permission not accessed
#19 WNDRazoR, Feb 8, 2017
That's because you haven't been able to install the 2 zips in the tutorial, one of which is the su.zip which gives you root access and superuser privilege. You need to get those zips installed. So yeah, either you don't have a working driver for mtp, you can try a different usb port perhaps, or place the 2 zips onto a physical sdcard (if this device has one) and install them from that instead so you don't need mtp at all.
#20 iowabowtech, Feb 8, 2017
i saved the files to my sd card and installed from there
#21 WNDRazoR, Feb 8, 2017
First off id just like to say thank you to all the wonderful minds who have helped me root over the years. This is my first time posting. If someone where to compile a one click method I would gladly donate in any way I could to support their cause. This phone is a giant pain in the ass and I'm glad I didn't get rid of my LG L70 of which I rooted long ago using this forum. I had 3 of the L70 and didn't worry about bricking it. This Aristo is unlocked, own unlocked. And badly requires root. Its advertised as having 1.5 GB of ram and only in fact has 1.3GB of ram. Its slow and often lags from not having any ram free while sitting at the home screen. Its sad that my L70 runs circles around it with half the cpu and half the ram. I would try the above method but of I brick I'm sol and I'm not afraid to admit that my coding skills are nowhere near the bleachers of the ballpark you're in Messi. Lol.
#22 DeathsKlown, Feb 9, 2017
You can unbrick the Aristo. I made a mistake during the rooting process a few days and bricked my device but, I found a guide to unbricking it that works and now have a rooted and TWRP'ed Aristo. Just follow Messi's directions to the letter and you shouldn't have any issues.

I had the L70 myself and I enjoyed using but, the Aristo is better than it in every way in opinion. Just give the OS a day or two to settle in. It's very smooth and lag free after that.
#23 LG Fanatic, Feb 9, 2017
So I ended up giving this a shot today, but I'm not getting very far. I unlocked my bootloader and flashed TWRP from fastboot, but when I try to boot into it for the first time I get a screen saying my software can't be checked for corruption and it tells me to push the power button and then boots into initial setup. Anyone run into this problem or know how to fix it?
#24 ManWithNoFace, Feb 9, 2017 Last edited: Feb 9, 2017
Getting that screen means the bootloader is unlocked. Don't worry it's normal. Which step have you gotten to in Messi's guide?
