[MENTION=3167089]runningnak3d[/MENTION] Thanks! The only issue is that I can't get into fastboot mode at all. USB Debugging and Allow OEM Unlock are both enabled, but issuing the ADB command "adb reboot bootloader" just restarts the phone normally, and every volume/power button + USB connection combination I have tried have only brought me to download mode, factory reset mode, and IMEI display mode. I read elsewhere on XDA that "LG removed fastboot commands for MM" but there were no details or explanations.
[T-Mobile LG V10 General] runningnak3d:
Interesting. First time I have heard of that. When I got my V10 it had 20L on it, and I had no problems. Was that a typo, or do you really have 21J and not 20J. I didn't even know there was a 21J if that is the case, and if so -- they may very well have pulled fastboot. The A-holes did with the V20s lastest firmware....

-- Brian
[T-Mobile LG V10 General] jetkov:
Not a typo unfortunately. I would post a screen shot but I can't as I am a new user. I don't really understand why LG has changed their stance about allowing fastboot access... makes me sad :crying:

It is strange because V21J is not even listed in the software version list on T-Mobile's support site. It goes from H90120j to H90120L (MM) straight to H90130b (Nougat)...
[T-Mobile LG V10 General] runningnak3d:
LG doesn't make that determination when it is a carrier branded phone. T-Mobile decides if they want to allow the bootloader to be unlocked / fastboot access /etc...

Without fastboot access, you are kind of boned. If you were to flash that TOT, you would brick your phone. You are in the same boat as the people that took v30b OTA, so you might as well upgrade.

If I can ever find someone on eBay that can send me a decent board so I can get my v10 working again, I will continue my pursuit to provide a safe root method for Nougat. Right now it is possible, but it is very risky (that is why I need a board off eBay :) ).

-- Brian
[T-Mobile LG V10 General] jetkov:
[MENTION=3167089]runningnak3d[/MENTION] I didn't realize that it was 100% the carriers choice. C'mon T-Mobile I thought you were the holy trail of carriers to is tweakers and developers!

Thanks for your help though, I'll probably just upgrade. I'll try and find a way into the system myself as well, if I get the time. Sad how much the logic boards cost, probably cheaper to get a cracked or otherwise damaged V10 with a good board.

[/COLOR [MENTION=3167089]runningnak3d[/MENTION] do you know if it is possible to downgrade from this version to 20j and then root? Also, is there a thread regarding the development of a Nougat exploit?
[T-Mobile LG V10 General] runningnak3d:
[MENTION=8473747]jetkov[/MENTION] I started a thread around here somewhere on rooting Nougat.

As for the downgrade, if 21J didn't increment the anti-rollback version, then you should be able to. I say *should* because some people have been able to roll back from Nougat, but most haven't even though the ARV is still version 2.

I know this much, you can not if you use the OEM USB cable. You have to use a USB 2 cable. If you try with the stock USB 3.1 cable, you will pass the ARV (if it is still version 2), but it will stop part way through flashing.

-- Brian
[T-Mobile LG V10 General] jetkov:
[MENTION=3167089]runningnak3d[/MENTION] thanks. I'll probably give it a shot and if I can downgrade, get rooted from 20J and then upgrade with root to Nougat I'll make a thread on it. Either way I'll report back to XDA for those few others who might have 21J.

Weird issue about the USB cable. Thanks for the tip.

Root on nougat?

Hi guys, i am really new in this kind of things (root and stuffs) but i am willing to try it anyway (you never try you never know, right? :p ). Just 2 days ago i bought a secondhand v10 for a crazy cheap price (at least for me), and i want to do some experiment on it though (mainly root but i got the nerve to continue the journey like custom rom and stuffs). For this moment, this is the v10 specs :

Model : h901

Andro Ver. : Nougat 7.0

Software Ver. : h90130b

It was T Mobile's V10 and one of my goal is to get rid that t-mobile boot logo ( i am from and live in Indonesia, we dont even have t-mobile here, so it so weird to look at, just a personal taste)

The questions that arise are :

1. Can i root it? How? The Same way from the first page?

2. I read the recent post and someone get into trouble try to root this? is it impossible?

3. If i am able to root it, is there any tweak needed for v10? ( i have good experience for v10 this past 3 days, but i am all in to all kind of treatment to improve the v10)

4. If i am able to root it and willing to do a custom rom, do any of you have a recommended custom rom? i need the lightest and most stable one, i dont really care if it is not really good to look at because this phone is my extra phone and if those experiment succeed i will use this v10 for my business phone cause right now i use s8 for everything.

Thanks guys, hope anybody would be so kind to help me.
[T-Mobile LG V10 General] theUsualSuspexx:
You know, I'm not at all one of them noob bashers. I understand that sometimes directions are a lil confusing, or your just scared of bricking your brand new $500 phone & wanna be extra careful and make sure to do it right, or heck let's face it, some of this is such second nature for most of us that there has been steps that we think are common sense, just plain left out of the instructions and can foul a noob up. With that said...

Bro you haven't even spent 2 fn seconds to do any research what so ever on your own and it shows. Here you are talking about making experimental tweaks, custom rom requests, and a bunch of other nonsense when even the dumbest person on Earth could of used Google search and spent less time than it took you to write them 3 paragraphs of jiberish, bragging that it was cheap for you because you a baller and it's just your backup phone and blah blah blah to find quite simply NO. You can't root that phone if it's on 7.0 you big dummy. So now instead of wasting time dreaming of new boot animations spend that time figuring out how to not bankrupt whatever make believe "business" you were going to use your un rootable, non light custom rom having, T-Mobile splash screen booting, never going to have a tweak or mod yet is still way better of a phone than your bootleg mediatek runnin, Chinese made "s8" is ever gonna be...

I've asked a few real dumb questions in my time with xda, but I guarentee there was no less then one & prolly more likely two weeks spent googling every possible combination of things to find an answer myself before ive ever even thought of asking on here. Better sell that V10 for lunch money and start taking yourself back to school mr. No school tomorrow.

#MicDrop

PS if there is anyone that even shows that they've put the slightest amount of effort into figuring it out themselves, id be more than happy to share every single bit of knowledge i have on this phone with ya, I'll even re upload the files if links are dead and give you live step by step directions if needed. But not with that guy. He sucks. ?
[T-Mobile LG V10 General] obliviousryuk:
any updates? i got 21j here, too, still wishing to at least get rooted since the nougat update is never gonna come
[T-Mobile LG V10 General] jetkov:
Yeah, I never got it to work, unfortunatley.
[T-Mobile LG V10 General] Mr Hassan:

where i,m doing wrong ?
[T-Mobile LG V10 General] 17mm:
i did this, even flashed the ota update that someone posted for nougat, everything was working fine until i decided to accept an 88mb update now it just loops to twrp, tried restoring, flashing original, still just boots to twrp.

i can get into download mode, fastboot also works fine, but nothing is getting rid of the twrp boot loop im having. should i reinstall twrp?
[T-Mobile LG V10 General] willy_itc:
Working 100% for me

i have test it and its not working too bad,......................:crying:

Anyone kindly share A kdz, tot, dz or dump file of a stock rom for LG H901BK (lgh90110c) t-mobile stock lollipop 5.1.1 firmware (Korean Board) please . it might help thousands.
[T-Mobile LG V10 General] demkantor:
A similar method could work, but if you do this it won't, may even brick your phone.
[T-Mobile LG V10 General] ReelFiles:
I figured it out and corrected my earlier post, problem was it needed to be oem unlocked over adb, didn't work just enabling it in the settings, thanks guys :)
[T-Mobile LG V10 General] headcreepz:
What about cm12?
[T-Mobile LG V10 General] trungvov10:
So no need to flash Eliminater74's rom anymore?
[T-Mobile LG V10 General] Eliminater74:
custom roms will work regardless...

custom is only boot/system

Not unless you want updates. Im always updating that ROM.. Like today for example..

But you dont have tooo..
[T-Mobile LG V10 General] nieves53:
Is the corruption splash screen still present with this method?

Sent from LG - H901 MM 6.0 Rooted using Eliminator74's Rom. ??
[T-Mobile LG V10 General] trungvov10:
I want to update but I also want some changelogs tho or I wouldnt know what Im update into.
[T-Mobile LG V10 General] ReelFiles:
Yeah man, I am still seeing the can't check for corruption message on every boot
[T-Mobile LG V10 General] pls3399:
Thanks for the brick. Everything was great until I tried the TOT file. Now all I get is Boot Verification Fail -cause : Mismatch_SIG_LEN
[T-Mobile LG V10 General] Eliminater74:
drop to fastboot and OEM unlock.. then it allows you to go straight though......... but you will get that boot corruption verification screen........
[T-Mobile LG V10 General] pls3399:
Is it possible to do this if my phone wont go into recovery? It only gets to the LG logo and then starts looping with that error in the left corner.
[T-Mobile LG V10 General] texas83:
Will this method erase existing data on phone or does it keep your data/apps? I'm on stock MM, bootloader unlocked, no root.
[T-Mobile LG V10 General] dimm0k:
this should retain your existing data, but it's always wise to backup just in case
[T-Mobile LG V10 General] lrwjr1964:
Someone asked this question already but I didn't see a response. If I am already on Stock MM do I need to still flash the KDZ or can we just go from step 7 to 13?

Also on step 11 (if I cannot skip):

11. Choose bin file choose kdz v20e H901 then choose REFUBISH

Do you click start after choosing the KDZ?

I am assuming the phone restarts since you have to enable OEM unlock and USB debugging again.

I just want to get this right the first time so I want to make sure I understand 100%. I have rooted all of my phones for years so I like to re and reread and ask questions if I am not clear on something. Thank you to all that have worked on getting root to this phone. You all are totally awesome!!
[T-Mobile LG V10 General] scloutkst:
Is their any advantage to flashing this vs eliminators rom?
[T-Mobile LG V10 General] alphahere:
Not really but this is pure stock with no special sauce.
[T-Mobile LG V10 General] scloutkst:
The reason I ask is I have been having cellular data dropping randomly. I'd like to flash 100 percent stock and see if it helps. I'm just afraid this finicky beast will end up bricked. If I flash stock and root, can I got back to debloated with eliminators part 2 zip?
[T-Mobile LG V10 General] dimm0k:
yes... the kdz will always bring you back to stock MM. the tot here is for people already on stock MM to get root/TWRP.
[T-Mobile LG V10 General] scloutkst:
Thank you for your clarification and swift replies.
[T-Mobile LG V10 General] lrwjr1964:
Thank you. I did the OTA a while back and unlocked the bootloader at the same time. So that means I can just start from step 13 of the guide correct and I should be good to go?
[T-Mobile LG V10 General] dimm0k:
yes... but you may want to double check your bootloader is still unlocked and backup your stuff just to be on the safe side.
[T-Mobile LG V10 General] YrrchSebor:
You can still get into those modes, I was in that same spot. With your phone off, hold volume down and then plug it into your computer... It should go into fastboot mode, and then you can do fastboot oem unlock.
[T-Mobile LG V10 General] lrwjr1964:
Thank you sir. I am backing up at this moment.
[T-Mobile LG V10 General] MudaTrucka:
I flashed supersu but when I give an app permission it still says there is no root access
[T-Mobile LG V10 General] Jaimesco12:
Does anyone know how to change the dpi?
[T-Mobile LG V10 General] trungvov10:
have u tried app on google play??
[T-Mobile LG V10 General] YrrchSebor:
I think you can edit the build.prop file too? But do dpi changes play nice with this phone?
[T-Mobile LG V10 General] gustav30:
Another happy camper here. Worked great. Only thing had to do like mentioned above was fastboot oem unlock.

Just make sure you backup cause fastboot oem unlock will wipe the device.
[T-Mobile LG V10 General] trungvov10:
Almost done yet I got fail to mount data in TWRP, couldnt flash superSU, and It keep rebooting in to twrp even chose reboot to system.

NVM I tried again and it is rooted now :D
[T-Mobile LG V10 General] chernabog88008:
Stuck at this point of the error in upper left. I'm in fastboot mode, but it keeps saying fastboot oem unlock fail. FAILED (remote: oem unlock is not allowed)

finished. total time: 0.007s
[T-Mobile LG V10 General] trungvov10:
did u check oem unlock in dev setting before?
[T-Mobile LG V10 General] headcreepz:
Can someone tell me the fastboot command to check bootloader status please? Thanks in advance.
[T-Mobile LG V10 General] trungvov10:
u mean checking if oem is unlocked or not?
[T-Mobile LG V10 General] headcreepz:
Yes
[T-Mobile LG V10 General] trungvov10:
just use fastboot oem unlock, If oem was unlock, it will say oem is already unlocked, if not, it will unlock oem
[T-Mobile LG V10 General] demkantor:
fastboot getvar all

Look for locked or unlock toward the end
[T-Mobile LG V10 General] headcreepz:
Thank you for the quick reply.
[T-Mobile LG V10 General] chernabog88008:
Fixed it, took a wrong turn at Albuquerque in there, but recovered it.
[T-Mobile LG V10 General] JMM2009:
LG up only sees tot files, I couldn't get it to load the kdz
[T-Mobile LG V10 General] BigSK225:
Check Upgrade, browse and choose the .kdz, then switch back to Refurbish. That worked for me.
[T-Mobile LG V10 General] offremike0887:
So, I followed the instructions, step by step. It wiped my phone the first time (which I was cool with), then I did the "Upgrade" part. After it rebooted, I didn't notice a difference, then I tried to download the recovery app (makes it much easier for me to get to twrp), I got a download failed error. I figured it was maybe because it was an app that requires root, but even trying to download facebook caused an issue. I then proceeded to start over. This time, before the "Upgrade" part, I downloaded all of my apps and got my settings back to normal then proceeded to the "Upgrade" part. It rebooted and nothing different, just like the first time I tried. I tried to go to recovery and that didn't work. I tried the recovery with the physical buttons and it brings me to the LG recovery menu. I read earlier that someone said the tot file had recovery within it, but that's not working for me. I tried flashing twrp through cmd and that didn't work either (yes I'm using the twrp 3.0.2 for MM). I tried "adb reboot bootloader" and it failed. I know the oem is unlocked and the developer settings are what they should be, but still nothing.

I am one of the idiots that upgraded to MM before anyone new it wouldn't allow you to root it and it gives that weird corrupted message ("Your device software can't be checked for corruptions") every time you start up the phone or go into download mode (not sure if that's the problem, but I can't fix that). I also tried to get it replaced through t-mobile but they claim all of the V10's in their warehouse are supposed to have the MM upgrade now.

Anyone know what I should do? (also attached screenshot of cmd message)
[T-Mobile LG V10 General] Double0EK:
I can tell that you didnt follow any steps from the OP. Nothing in the OP says to fastboot flash a recovery. So if you actually want to root then actually follow the OP instructions.
[T-Mobile LG V10 General] MudaTrucka:
To go into twrp after the upgrade part I went into fastboot and then did the command, "fastboot reboot recovery" and it then booted into twrp so I could flash supersu. Hope this helps

Edit: Make sure you're using this file for the upgrade part https://docs.google.com/uc?id=0B8mSVItI_cqRc0NPVlEtZmxqb2s&export=download
[T-Mobile LG V10 General] djnikkofb:
i was already on MM..

my steps...

1) hold vol DOWN plug in to PC

2) ran fastboot OEM unlock

(this wiped device, and caused boot load image of "device cant be checked for corruption, not a big deal 4 me). when it boots, go back to dev option and select USB debugging (oem unlock was already ticked)

3) power off phone

4) hold vol UP, plug phone in to PC

5) run LGUP and continued w/directions of flashing TOT.

6) got in to TWRP, flashed SuperSU

7) profited

[T-Mobile LG V10 General] Ficticious:
No, root doesnt seem to be working either, but thats probably because i havent been able to install SuperSU. And i cant access recovery so :/
[T-Mobile LG V10 General] Swizzle82:
What have you tried? The manuel way is kind of tricky on the V10. It has to be at the right time to release the power button and repress.

In preferences backup location click on filesystem right above Detect and switch it to document provider. Select the menu on upper right to show SD card and select it. Than select create new folder. This allows you to backup, I haven't figured out if it's possible to restore apps from Lollipop.
[T-Mobile LG V10 General] dimm0k:
nice! looks like these platform.xml edits are no longer needed... any idea about Tasker and other apps that don't have something like that implemented to be able to write to the external SD? I used the platform.xml edits and they didn't work...
[T-Mobile LG V10 General] jevers77:
Nope sorry. After you say that I hope I don't run into problems with my SmartThings hub and functions for controlling things. I just finished the root process and am restoring my phone right now. I just knew about the Titanium thing as I told my brother about it when he was having problems after trying the other root method that warbeard was suggesting and he screwed up his phone but got Marshmallow with root through Eliminator.
[T-Mobile LG V10 General] SasamiAdachi:
I followed the instructions up to launching the LGUP application. I see my phone appearing in the LGUP, but the Process frame below it is empty. I copied the common folder to C:\Program Files (x86)\LG Electronics\LGUP\model and restarted the application. But the Process frame remains empty. Any idea on what I am doing wrong?
[T-Mobile LG V10 General] demkantor:
Did you direct lg up to the .tot file?
[T-Mobile LG V10 General] SasamiAdachi:
I managed to get past the LGUP issue by using LG Bridge instead.

---------- Post added at 07:03 AM ---------- Previous post was at 07:02 AM ----------

I launched LGUP after the update but the Process frame remains empty - there are no refurbish, upgrade or any button in that frame. My phone is identified as H90120e on STANDBY connected to COM6.
[T-Mobile LG V10 General] trungvov10:
what did u do with the LG bridge lol
[T-Mobile LG V10 General] SasamiAdachi:

I think I figured it out. My PC needed to be rebooted after the applications were installed. Now I see the four radio button options showing up in the Process frame in LGUP.
[T-Mobile LG V10 General] offremike0887:
1. if "OP" means original post, then YES, I DID. I even mention in the post the same instructions mentioned in page 1.

2. I NEVER said the original post said to do fastboot flash recovery, I'm just saying I tried doing that and it didn't work, AFTER following the steps.

You can try it, it will work depending on what is edited, but always have a copy of original and know how to use adb to restore if things go wrong
