Yes you can. The LGH631 and the LGMS631 are both the same devices essentially, same exact hardware on the same exact network. I personally used the 5.1.1 T-Mobile bootstack and the returntostock zips which I flashed via TWRP after rooting. Stay stock unrooted 5.1.1 and then jump on your wireless network and wait for the update. I was able to keep my Metro apps this way.

Thanks for your contributions to the Xda Community and also helping us Stylo Owners even though you jumped ship to the G4 but i dont blame you for advancing to better technology im the same way, I was a Boost Stylo owner but switched to the Metro variant because it has better specs. Anyways Thanks again Draken

I don't believe LG Flash tool works anymore, at least not for our phones. I was lucky enough to get Marshmallow through the OTA after reverting back to stock, but when I first got the phone back in October last year the first thing I did was try to root it and bricked it. If you download LG Bridge there's an option for "Update error recovery" on the bottom right of the software update tab and you can sideload a kdz file there.
Here is where you can get USB drivers for the Stylo.

Thank you. Just trying to get this figured out in case Draken is unable to get his zip fixed. I'm currently rooted on 5.1.1 and trying to go to marshmallow

Not a problem. Happy sideloading, but keep in mind that a kdz is a full return to stock and you'll lose everything on internal storage and you'll be setting it up like a brand new phone. Then again if you're going to root it using the guide on here you'll lose all internal storage data anyway so...
Regardless, good luck!

There is a method to flash the T-Mobile kdz file 10j and then OTA update to 10L and then to MM.
I was rooted on Lollipop/Katana ROM and did this method and am on MM/T-Mobile variant, then rooted after MM update.
LG Flash tool was used to flash the Tmo kdz 10J file (lollipop).

I haven't been able to flash the MM kdz with flash tool only able to recover using earlier kdzs. Has anyone been able to use the 6.0 kdz in flash tool?

@DrakenFX are you still around? you dont have this phone anymore right? does that mean you wont be able to make a flashable zip of the metro mm kdz that is finally out? heres the link just in case http://www.mylgphones.com/metropcs-...receiving-android-6-0-marshmallow-update.html
just another question to anybody that might know regarding that lg up tool...i just used the lg flash tool to flash back to stock so that i would hopefully get the metro mm ota...well it worked perfectly and i was able to get back to stock just fine, but now i still havent received the ota...so im wondering, if the flash tool worked for me, can i use it to install the metro mm kdz instead of using lg up?

Hey,
LG UP is a new and easy tool from LG Official. It can flash kdz/tot/dz files.
You can use "LG flash tool 2.0.1.5 or above" to flash kdz/tot/dz files.
The LG flash tool 2014 is a tool modified by some one from Vietnam, I did not test it.

I encountered the same problem with my LG F600L when I was trying up upgrade from MM to Nougat. But before you start did you check the Anti-rollback version first if you are in V0 then you should be good to go. What I did to revive my phone was I use Uppercut. To do this, look and download for Uppercut get it here Uppercut. Once you have downloaded Uppercut close LGUP. Just pull the battery of your phone and re-insert it will boot to download mode automatically, plug it in now DO NOT launch LGUP click Uppercut as this will call LGUP to open automatically then select refurbish and select your KDZ then click start. Tell if this works for you. By the way, make sure to turn off your antivirus as this will detect Uppercut as false positive and it will not run.

Restore v20 to 100% Stock (!!even for bricked devices!!)

This is a simple method to restore your v20 to stock, I have tried with my bricked H990DS with wrong bootloader flashed.
1. Download .kdz file for your v20 model from the following links. Currently v20 models available are:
F800K, F800L, F800S, H915, H918TN, H990, VS995, H990N and H990DS
H990DS https://lg-firmwares.com/lg-h990ds-firmwares/firmwares/
H990N https://lg-firmwares.com/lg-h990n-firmwares/firmwares/
https://lg-firmwares.com/
2. Search, download and install LGUP ( LGUP_Store_Frame_Ver_1_14_3.msi ) and a file called LGUP_common.dll
2a. Copy the LGUP_common.dll to C:\Program Files (x86)\LG Electronics\LGUP\model\common (May need to modify folder access right)
3. Search, download and install LG Driver ( LGMobileDriver_WHQL_Ver_4.1.1.exe )
4. Completely Power off the v20 ( or to remove and put the battery back )
5. Plug the USB end of sync cable to your PC
6. Press and hold "Volume Up"
7. Plug in the USB-C end of sync cable to the v20. The phone will enter download mode (or Firmware Update). Now you can release the "Volume Up".
8. Run LGUP. The program will regconise the v20.
9. At the file path, click "..." and chose the .kdz file
10.Choose "UPGRADE"
11.Click "Start" and wait until the process is complete.
Now we have a safe method of restoring bricked v20. Hope developers can start trying to root without worrying of bricking the phone.
This method is verified on my H990DS. If anybody successfully flash using this method please let us know. Thanks!

Great thread! Just want to add a quick PSA for this:
This may update your phone to the latest firmware which may patchs the current recowvery exploit. While this will unbrick your phone, you should make sure that you have the a firmware below 10i (w/o patch) to flash. If you still have access to TWRP and don't have a 10d firmware for your device, use this instead.

This will update your phone to the latest firmware, 10i (your phone came with 10d). The latest firmware patches the current recowvery exploit we use to root our V20s.

Thanks for the reminder. Actually it depends on what .kdz is available. For H990DS there is actually v10b firmware for download. So after I flash using this method the dirtycow exploit is still there. Take a look at the filename of the .kdz (e.g. 990ds10b_00_OPEN_TW_DS_OP_1125.kdz is v10b released at Nov 25) Seems that versions below v10i are still ok for dirtycow.

Ahh! Nice! Hadn't considered that. I'll update my OP

Darn. Got my hopes up. No VS995 in the list. No T-Mobile and no Sprint either. I don't need it....yet...but I would love to have a restore method for my VS995. Though I've had an LG G3 rooted and flashing custom roms, kernels, and mods for 30 months and never once restored it to stock so perhaps the V20 will be the same

are you using uppercut for the model .dll in LGUP?
i have tried this method a few times over the last week, no luck. but i was pretty rough with my phone to be honest, no backup and tried all the other v20 variant roms.
right now LGUP detects my phone as a US99610D so will not flash the H990DS firmware, tried to edit the kdz in hex editor for name value but it detects the kdz as corrupt now. any experience with this?

What do you mean?
If this method worked for you & a few other users, it should probably become a sticky rather than closing the thread...
Unbricking a device & restoring to 100% stock is an important feature to most, so if a few users are having issues we should probably help sort out those issues rather than abandoning the thread...

don't close it off, if it worked for you it should work for others that haven't broken the phone quite as much as me (boot, recovery, aboot and system changed).
the dll looks to be a requirement, perhaps uppercut worked for you prior to you AV killing it. i used it despite the AV alert.
so that part works fine, my phone is detected as version US99610d (files used during root attempt) which prevents me running the KDZ with "Error: KDZ file is invalid. US996 -> H990"
i tried to edit KDZ file to change version from H990 to US996 but this just corrupted the file.
i edited the model in build.prop of a rom and flashed it but it failed to make a difference to LGUP.
in a last ditch effort i restored aboot.img but phone is still detected as 996 instead of 990. but now no more twrp or unlocked bootloader.
any idea what LGUP reads the version info from or how to force it to run a KDZ from a different model?

LG v10 H901 (with Korean board F600s) Update to 6.0/7.0 without Brick

Salam Everyone!
Today i'm going to post About Lg V10 model which says it is of T-mobile (from boot animation) but when you remove battery it show Model H901 (Made in korea) So it is huge confusion between users of this phone. Let me clear this one first, your phone consist of board same as LG v10 Model F600s so if your lg Bridge shows an update of something like "F600S30D 05.27.2017" dont worry it is saying this according to board requirement (Warning: Never update your phone using LG Bridge otherwise you are going to brick your phone). LGup is best for updating LG firmware’s.
Now let’s come to the point on how to update this model to Marshmallow and Nougat. And one thing Do this step by step as described in steps below (one thing i'm not a developer i just do little internet research and with help of some friends i was able to do it without bricking my device).
This you need is for update is Kdz for Marshmallow and Nougat and LG up Software.
Installing and fixing LGup ‘unkown model’ problem:
I've seen some people complaining about lgup not picking up this model so here is a fix you can do it to make it work:
Download LG up software using all the links given below:
Now do it as I say.
- Install LG UP LAB Ver. 1.10
- Install LG UP Store Ver. 1.14
- Install LG UP Ver. 1.14
- Now most important is this file LGUP_8994_DLL_Ver_0_0_3_23
(Now here is a Check whether your LGup is installed properly or not scroll through follow the following address and check is there “Common” folder have File “LGUP_Common.dll” If not please try this process again.
Address: C:\Program Files (x86)\LG Electronics\LGUP\model\Common
And after you are done with installing LGup now time to check if this is working remove back cover of your phone (unplug your phone from USB cable, remove the battery, insert battery while pressing the Volume up button and now plug the USB cable. Your phone will turn on automatically with Download Mode on and yes LGup will recognize your phone immediately without any further delay. Showing Model as “H901”
How to check Phone model using Lg info app:
There is one little check you have to do is… go on play store and download Lg info app install it and check your phone info.
Scroll down and See “Provider Name”: (Now here we will see the exact model number of your phone)
- If it shows SK Telecom This means your phone model is LG F600S aka LG V10.
- If LGT this means your phone model is LG F600L aka LG V10.
- If KTF this means your phone model is LG F600K aka LG V10.
Now after Confirming Model Number Now download the relevant firmware but keep one thing in mind do it step by step don’t try to flash direct Nougat on Lollipop okay this will brick your phone as well.
Updating Marshmallow from Lollipop (6.0 from 5.1.1Stock):
As assumed you have downloaded your concerned firmware (you can do a little search on Google and you will find relevant kdz if you need further just p.m me)
- As I have LG F600S aka LG V10 so I will tell you what steps I used.
- First download F600S20l_00_0503.kdz
Now same take your phone in download mode and let LGup recognize it now Select it under BIN File and (Check the Upgrade option) now press start and It will start upgrading. Leave it for a while and let it complete. Now your phone will turn on without any brick  V10 will download some OTA software updates (as it happened in my case). Check your software Update it will surely say 6.0 
Updating Nougat from Marshmallow (7.0 update):
Download the latest firmware from LG firmware website that says “ 7.x Nougat” in my case it was “F600L30e_00_0517.kdz” (Model F600s)
Do the same as you did while updating to Marshmallow. It will successfully update your phone to latest version. No further complications are there in this step it is so simple.
Some Warnings:
- If you are going to use my technique to update please do it carefully do not skip anything.
- I’m not responsible for any kind of brick phones SD cards. As I said I’m not a developer I’m just like you guys was looking for update my phone and done it will little research and help.
- Do not unplug your phone while LGup is updating your phone.
- I’m not developed any software or any update so it is all online stuff nothing personal: D
- And I’m here to help other please feel free to ask anything form me  I’ll try to help as soon as possible 
You can message me on Whatsap I’ll create a group for help on whatsap as well.

@hapyfaroq as you mentioned, you have flashed Marshmallow F600S20l_00_0503.kdz !!! and for Nougat you flashed F600L30e_00_0517.kdz !!! which are totally different models. could you please recheck if you typed F600L30e_00_0517.kdz istead of F600S30D_00_0510.kdz

Everything is double checked and then posted so no mistake in the article

Mine is KTF but now running fine on F600L Nougat (and the pcb says it's F600L), not sure what's really happen here. It was H901 Tmo before got bricked.

Thanks @hapyfaroq @runningnak3d for your time & help
Failed several times and gave up with LG UP. So i took my phone to a mobile service center who is good at software flashing. i gave him nougat kdz F600S30D. He converted kdz to dz format and flashed with Octoplus box. my mobile was on 5.1.1 android and directly flashed Nougat. Booted flawlessly and no network problems as well Everything is working just awesome. attached my video of Nougat Overview

All you need is to carefully install all the software and yes there is no need for DLL file after installing these softwares

Hey what if I have a T-Mobile H901 with VS990 motherboard in it? By the sound of things, I would need to flash vs990's kdz. However, wouldn't Tmobile's h901 kdz work as well? I don't understand how your modem and boot screen img(tmobile) wouldn't be affected by flashing f600 kdz to tmobile phone.

bro as i explained in detail that flashing H901 kdz on phone having different board in it cause it a brick so better to flash such kdz which is compatible with the board.... Be careful double check with your board model. (this is the most important part) Keep that in mind that if you are going to flash some other kdz it will not work and will brick your phone.

i have everything ready but lgup never found the phone as a MODEL.keep saying "unknown model".
i ve checked lg bridge it founds 2 updates (im on 5.1.1) , lgbridge founds both 6 and 7 updates.
i've downloaded the kdz file according to the bridge and and phone provider(tmobile)
but i don't know if i can flash it with LG flashtool besides LGUP.
Because i can not pass "unknown model" issue.

Read the Article carefully it says never update your phone using LG Bridge it will brick your phone, and for kdz please search lg firmware on google and download the relevant kdz as per the model of your Phone's board. Don't waste your time downloading wrong kdz and lg up is hard to setup... keep on searching you will sure find a fix soon. Do a deep google search (as i did) you will figure out what is the problem behind Lg UP

Wassalam Farooq
The issue is that my LG info says its : T-Mobile H901BK
It's on 5.1.1
I have the correct KDZ for Tmobile.
Using a win 10 64 bit OS.
Deep uninstalled all LG soft and drivers
then followed your advises step by step
but still "unknown model"
I need to make first LGup to let find the phone.
I m not sure if i have f600s motherboard.
do you have further advise ?

Bro first of all you need to confirm your phone board model using Lg info app ... you can find it on playstore for free and for lg up do all as i said above then turn off your phone remove the battery... plug in the usb cable... now install the battery while pressing volume up button it (make sure you lg up software is running) then your phone will directly go into download mode and Lg up will sure recognize your phone model but first of all confirm your phone's board model.

LG Stylus 1 Downgrading to Lolipop from MM

Looking for a method for a long time, now i tested this and it worked.
1. Setup LG UP
2. Download a lollipop firmware (KDZ) of your choice
3. Download WindowsLGFirmwareExtract
https://forum.xda-developers.com/showthread.php?t=2600575
4. Use WindowsLGFirmwareExtract to extract .dz file from kdz(step2)
5. open LG UP select, select upgrade and select .dz file. click on refurbish and click on start
6. phone will flash, lg up will be 100% first, phone will be still at 99%, wait for 5min it will restart

Does this work for 9008 mode?

dont think so, only if lg up can detect the phone

Does this only work on certain models? I have a ls770. what do you think? Thanks
