Does anyone know to unroot it and go back to stock?

Does anyone know to unroot it and go back to stock?
My speaker got broken. I need to send phone for replacement. Im not lucky one
thank you so much for help

Find the stock tot for your model and flash it-that should return you to stock unrooted.

As far as I know tot file flashing doesnt work because dll's files are missing.

No harm,no foul,we've all done similar on at least one occasion.
You're a good man for offering to help ! :good:

Any help with that?

I am also awaiting an answer.
My last 2 Samsung phones had issues and I needed to Odin back to stock for warranty exchange at T-Mobile.
So I'm holding off on rooting till we have something of the sort for the v20.
Using Odin to flash my s7e back to stock while having severe screen issues saved my butt.
I'm on JoD for reference, and needed to switch phones at a brick and mortar.
Side note : loving the blooming development for this device.
Thanks for that, all parties concerned.

I believe in jcadduono root thread he says you can relock bootloader and flash his stock imgs in Twrp to be back on stock

Sound very complicated for newbie. Anyone can try it?

I made an easy to understand guide to do just this.

Does this unroot method work for the sprint variant? I am stock unrooted on the build the phone came out of the box with, and waiting until rooting isn't a one-way street to take the plunge. If it does, are you 100% certain that it had been used in sprint v20s successfully?

That thread specifically says H918. So no.

You are in the exact same position as me. I'm excited that we have an unlocked bootloader and root for the Sprint variant, but I have no desire to do anything until there's an established procedure to unroot and revert back to stock.

Here's hoping it's taken care of. Sprint didn't used to be such a **** when it came to bootloaders. Anyways, I appreciate all the hard work the devs have been doing. Can't wait until I get the chance to experience it. With a stable 200mhz overclock, there's no functional difference between the snapdragon 820 and the snapdragon 821.

Do any of the posted methods work to restore the VS995 variant to stock?
I really want to go ahead and root it (and yes, have disabled updates so still run 12A since I knew VZW was going to be evil and patch it) but I'm very hesitant to do so without a way to restore to stock. Is it one of those things that's just a matter of time, or is there a substantial likelihood it may never be possible?

LG V20 T-Mobile Rooting - Soo many threads; I have no idea what I'm doing

I've done a bit of research, searched through threads on this forum, and I still have no idea what I'm doing. The last phone I rooted was a Samsung Galaxy S2 Skyrocket.
What's the simple-man's way of rooting the T-Mobile variant of the LG V20? I see the below threads:

First which firmware are you on now? 10i, 10j, 10k, what? I think 10k is not rootable. But... If you have older firmwares then you can root with dirtycow method. it is not that hard. I think the hardest part should be to try to flash the twrp (but even that was easy at least for me an average flasher and tester). If you have any issues, the system will usually restore to the original image as a last resort.

The 10j kdz version is to be flashed with LG UP if you needed it. but up to now it is better you dont move further from 10j, because 10k is not rootable (i believe I've seen). If you want to have 10k you can flash 10j and then flash via twrp a zip of the stock rom with 10k

I'm at the last step; are there any advantages to disabling encryption? Any reason why I may/may not want to do this?

Encryption is mostly used for companies as extra security . But if i dont misremember , it is necessary to do it. Best thing would be to follow the instructions provided on the original thread.

T-Mobile LG V2010t
Hey all I new at all this and I'm trying to unlock or root my T-Mobile LG V20. I've never done any of this stuff, but I want to be able to use this phone on a network other than T-Mobile. Can anyone give this rookie ( me) some help?
T-Mobile won't unlock it for me. The day there is a balance owed on it. And when I tried the unlock app. It say failure in processing the request. Please reboot and try again.. If you can walk me through this it would be greatly appreciated. Thanks all!

Why did you reply to a post from last year for this?
Rooting has nothing to do with network unlocking the phone (and if it's on 10t or really anything past 10k it's unrootable anyway).
Your best option is to get T-MOBILE to unlock it, otherwise there are some other third party websites which may be able to unlock it for a fee.

I'm sorry my bad. I'm new here and did know how to start a thread. I just thought someone here might be able to help me. I didn't want to cause any problems. But I've tried T-Mobile support,T-Mobile store' called around here and tried several online 3rd party. And because of the message I get when I try to unlock it, nobody can help. So I figured there were some smart people here,they might be able to help me (rookie). Sorry I caused you trouble.

H918 10P root?

Is there any root yet for H918 10p if so... Please direct me to it asap lol. If not I might have to warranty exchange and then root or wait.. Thanks guys!

10p currently can not be rooted. There are some thoughts and ideas floating around, but more than likely another Linux kernel exploit will need to be found. Also, just an FYI, T-Mobile incremented the ARB version for 10p, so don't try to force an older version to flash -- that will blow the qfuse, and that is a hardware issue that can't be fixed without replacing the CPU.

My first Android phone was an HTC EVO 4G (the original WiMAX version). The first one that I got had an HBOOT with S-ON (locked bootloader). Reading on here, I found out that there were versions with an older HBOOT that had S-OFF, so I carted my butt down to the Sprint store and didn't even make up a story. I told them flat out what I wanted, and since I was still within the window of being able to cancel my contract, they took me back and let me look at the boxes that they had. I found one with the proper version, opened it up, verified that it was truly S-OFF and that was it.
Now, that was back in 2012 and things have changed since then. But if you just bought the phone, take it back and tell them exactly what you want. The LG V20 box has the software version that is installed on the UPC sticker.

Brian,
I'm not sure what version of the V20 you have, but I've got the H918 and I'm running 10p rooted with Magisk. I started with SuperSU, but wanted to start over and try out a systemless root. Real simple steps too..
1. Unlock bootloader
2. Flash SuperSU or Magisk
3. Root achieved.
I attached a couple of screenshots. How easy LG phones are to unlock the bootloader and flash root is the reason why I always buy LG phones, not Samsung.
Cheers!

Can't flash an su method if you can write to the boot partition (twrp)

So no way possible to root then? My V20 is running H91810k and I have been looking for a way to root it but moments ago it turn off by it self on 13% and the update for 10p was in schedule....
Guess Im out of luck if when it turn on update itself.

@joesee You were on stock 10p? If so, how did you flash TWRP so that you could flash SuperSU? fastboot flash recovery does not work with 10p.

Don't know where you get your information from, but a qfuse will never be triggered with oem unlock on. and all it is is a warranty bit. just states that your warranty is void to the manufacturer.
They do have an anti-rollback counter but that is something totally different than a qfuse.

He probably rooted with original build out of the box firmware and installed a rooted 10p via twrp

Has an ARB system ever been rooted?
I'm new to LG anti roll back.
We have a quasi-root with 10P, if starting from 10J.

They only upped the ARB number because DirtyCow was fixed. Likely wont up it again until the next root is patched.
Doubt there is a way to mess with KDZ's to be able to make them flash. someone would have done it already.

Will Flashing a Oreo kdz of H872 on H871 brick my phone?

I have already flashed my h871 (at&t) to h873 using LGUP (partition dl). I heard that TMobile uses different software so I am curious.

Did you have any luck with this? I recently switched to T-Mobile and am using my AT&T G6

Ah really? Glad I didn't lol. Will I ever get OTA software updates? Also, do you know why it would brick exactly?
Thanks!

I know nothing about ota updates, especially not in the case of usa models.
It will brick because tmo ordered an extensive security package from LG. Their phones can not be flashed with any other bootloaders from other models, neither can other models flash tmo bootloader.
If you do you'll have a hard-brick. Nothing can be done, it's out of our hands, only LG/TMO could fix it.

Noob Question Please please reply....

Hi,im using a couple phone,ip8 and an LG G4 LS991,i love lg but things that i hate is this g4 is the bootloader cant be unlock coz my device antirollback was v4 and i cant root or modifying the phone.
Looking for a month but many thread say the v4 cant be bootloader unlocked.
So...
I want buy a brand new LG V20 or a Refurbish one,but thing that i want to know,is there a version of the V20 that the bootloader cant be unlock and have a antirollback version like the LG G4 LS991???
Please answer me,your ans very helpful,after solved ill delete the thread.
Huge Thanks.

Whatever you do, don't EVER buy a phone from Sprint. You really should stay away from ALL carriers, but if you must buy a carrier branded phone -- T-Mobile is the only choice.
For now, the LS997 (Sprint V20) is the only model that can't be rooted.
