Hello!
I'm currently on V521_20f, I have successfully root the tablet before, but due a softbreack I reflash it with the same rom but when I tried to root it again (dirty cow method), it get stumble and stay unrootable, so please if there is any possibility to downgrade to MM and get rid of the Nougat (I already tried to flash V521_10e.kdz and the LGV521_10c.dz with either LGUP, and LGFlashTool2014 without any success )

So, a friend of mine has a VS985 and wants to upgrade his OS. We live in Romania, by the way, so no Verizon for us... so no OTA's for him...
He currently has KitKat, and wants me to flash his phone to LP (or Marshmallow... dunno, some custom ROM, we'll see). I basically have to unlock the bootloader (right...?), put a custom recovery in place and be done with it (cause from that point on, I know all I have to do is get a custom ROM going and voila).
Problem is... I've had a LG D802 (International G2) for a while, and back then, I heard that with G3 the procedure is much harder (the procedure required to get custom stuff going). Worth mentioning is that he doesn't care about warranty (as he doesn't have one), so in case there are multiple ways to do this, the easiest one (even if it implies relocking the bootloader for warranty purposes is impossible) will do!
I really apologize for having to do this, but I am short on time, so I can't afford to research the forum and see what I need for this task. My plea is : perhaps someone who gets to read this can help, and provide me with the tutorials needed to do this?
Yeah, I know... "search the forum you noob'...

The software version of his phone is Android 4.4.2, VS98510B.
If he doesn't care about root/custom roms/etc, just use the LG Flash Tool to install the latest official 35B firmware KDZ (LP 5.1.1).
If he wants root/custom roms, there is no bootloader unlock for the Verizon G3, but Bump accomplishes the same thing essentially.
Root (10B should be rootable on the phone itself via towelroot), flash bumped TWRP recovery, and clean flash whatever bumped custom ROM he wants plus the necessary bootstack.

He said he doesn't care about custom & all that, but just decided stock isn't good enough for him anymore ( :good: ), so I'll have to throw a custom ROM on his phone.
Bump. Ah, yes, that's what that was! All I have to do is root it (which is pretty easy, kind of like AutoRec back in the G2 days, if you know that?) and flash a bumped recovery on it?
10B can be rooted on the device itself via stumproot (http://forum.xda-developers.com/lg-g3/orig-development/root-stump-root-lg-g3-sprint-verizon-t2850906), or I believe towelroot also works. Then, you can flash the bumped TWRP (http://forum.xda-developers.com/lg-g3/orig-development/recovery-twrp-touch-recovery-2-8-2-0-t2966129) either via Flashify on the device itself, or with a computer via ADB. Then just download whatever custom ROM you want and the necessary bootstack onto the microSD card, boot into recovery, and clean flash the bootstack and the custom ROM, reboot and you're golden.
(Check the ROM's topic to know which bootstack to flash. Some ROMs like XDABBEB's VS985 and CM13 use 35B, while I believe CM12.1 uses 24B.)

What's that boostack all about? I'm confused, why does it matter, as I'll flash a whole different ROM...

I rooted my Kyocera with Kingroot, worked well. Wasn't to keen on some of the files it was adding and found I couldn't unroot with Kingroot built in feature. So I then found I could use SuperSu-Me to rid myself of Kingroot and purchased. It removed Kingroot and I am still unable to uninstall root so that I can upgrade to lollipop. All I get is software update failed. Any suggestions. I even did a factory reset and phone is still rooted. I have not tried any install and custom roms.
Did you ever fix this?
OTA uptate to lolipop bricked my phone... I was able to find a Rooted 5.1 rom to rescue it. But like you, I cannot remove root and all future update attempts keep failing...
Did you try to flash a stock 5.1 rom on your rooted 5.1 rom? That should allow to get back to normal upgrade (back in time, it usually worked, still I am not aware of latest android pains regarding that matter)

I am not sure you need it to be verizon to just be able to leap to "future" android version, unless this version is only available via kies from your PSP/carrier.
flashing any stock rom might work. Alternative would be to find an unrooted kernel for your android version of a rooted but else stock ROM (as some people do as they like TW experience but with the added benefits of root). But they are just guesses, I wish someone with more technical know-how would join, I just talk from past experiences, not from current ones, so it might have changed.

this phone may have been carrier specific to Verizon...
I did find some custom roms for marshmallow and nougat. But that's totally new territory for me to learn how to put those ones on and of course no updates. 5.1 is as far as the Brigadier went officially. This was not a common phone so it's support and information for it is scarce

This is the update it keeps asking me to install , and it keeps failing . I suppose if anybody had a fully updated ROM for the Brigadier that would be useful solution...

Do you have xposed installed? Sometimes that can cause problems.
I do not, I am going to attempt to put TWRP on and then flash the Super SU Binary so that I can run FlashFire.
Lots a learning lol
Locked bootloader. You can run TWRP from adb but you cannot permanently flash it to the device.
I rooted with Kingroot and updated my phone. It was on 4.4.2 1.102vz. My phone boots up but screen goes blank after the Kyocera screen. I powers it off one time but it was luck. I can boot it into stock recovery. I would like to flash the 5.1 ROM to it and beagle to use it. I do not know how to flash a ROM to the phone since it does not have fast boot. Can anyone assist me? The phone was new and never used too. Was going to be a great phone for me at work. I have rooted before and took a ota and I only risked loosing root. But that was with Droid phones. That is where I have more experience in.
I have my T-Mobile LG V-10 rooted with Sir-Altus rom currently.
Without starting a fight or anything, I am trying to find out how I could go about restoring my phone to stock to be able to accept the Marshmellow update successfully without bricking my phone.
I understand that there is a difficulty in rooting Marshmellow and I am OK with that.
Can anyone link to a step-by-step on how to restore my phone to fully stock so I can accept the Marshmellow update and apply it?
Thank you,
Whiteice

Should be pretty straight-forward. Also as an FYI, you now CAN root you LG V10 starting from 6.0 (Marshmallow) stock. So there's really not much risk involved. I think the upgrade from 5.1.1 to 6.0 relocks your bootloader so...i don't think you have to do much. If you have an upgrade option in your settings on the phone you can take it or you can go to the LG website and download the software and follow the steps. http://www.lg.com/us/support/mobile-software-updates
Can I accept the update on the phone rooted and with TWRP installed?
"I wouldn't do it by just downloading the update and installing it through the ui", you'll probably get stuck in a boot loop on the lg logo boot screen! Try researching kdz or tot flashing! Youll then only have to click a few times on your PC and after that the file should just upgrade the phone through your USB hub
You can uodate using Eliminater74's Rom.
Flash Part 1 - Dont Reboot
Flash Part 2 - Dont Reboot
Flash Super SU
*in Eliminater74s Rom OP it says to use Fastboot again to OEM unlock. Just read it thoroughly*
Hello all.
Back when 6.0 was a new thing to install, I installed TWRP and upgraded from 5.1.1 to 6.0 rooted version. The phone is currently on H90120e and the build number is "built.with.SuperRs.Kitchen"
My question is this. Is there any way to relock and install the stock bootloader and return my device to full stock? Should I be installing a 6.0 bootloader or 5.1.1 bootloader and rom? Because even though the phone is on 6.0, I remember the TWRP and all the other the hood files were special because the install method to 6.0 was special.
Or am I just stuck with a phone permanently on a 6.0 with no way to ever take OTA updates and never be able to return my device to stock?
It's been a while since I've done romming and rooting so I apologize if I'm using the wrong terminology.

If you're ready to go back to stock, look for the KDZ file for 20J and use lgup to refurbish your phone. You could do the 20L version from http://forum.xda-developers.com/showthread.php?p=69311017 but not many have gotten that OTA yet. I did flash the 20L zip, and have no problems, but YMMV.

will using LGUP remove TWRP and also remove the error screen at bootup saying the device can't be checked for corruption?
answering my own question, i had to fastboot oem lock but asfaik my phone is completely back to stock now thank you
Hey XDA, I'm having a bit of a problem. I got my G5 just recently and I wanted to go ahead and unlock the bootloader so I could install some custom ROMS (I'm not a fan of LG's ux), but I ran into a sticky situation. I was trying to flash the TOT file for rooting h830 with LGUP when I found out that it doesn't work on Nougat. I tried to cancel it but now I'm just stuck in firmware update at 0%. The code at the bottom says 633A B50. I can get into fastboot but I can't really go anywhere from there and I've gotten to stock recovery but all it does is factory reset and boot me straight back to firmware update. I downloaded the stock nougat kdz file but LGUP won't flash it; sometimes it says invalid, other times it gives me the error code 0x2000 CEFS::Initialize. This is a brand new (kind of expensive) phone and I can't send it to LG for repairs since I unlocked the bootloader and probably voided warranty so I'm really desperate for a solution. Can anyone help me out?

Was your phone on the 20a version before you tried flashing the 10d root tot file and did you actually cancel the process within LGUP while it was flashing the phone?
Another user had a similar problem but he flashed the 20a version before he accidentally flashed the 10d root tot and he fixed it by just flashing the stock 20a within LGUP.
Assuming you can still get into download mode you should be able to fix your device.
Try flashing this kdz uploaded by @autoprime
downloads.codefi.re/autoprime/LG/LG_G5/H830/H83020a/H83020a_00_1107.kdz
If flashing is successful factory reset your phone from the stock recovery after.
Thanks, that worked but I had to do a little tinkering before it did. LGUP wouldn't flash it because it kept saying invalid and some other random reasons but I found a program called uppercut that allowed it to flash. I was able to get back to stock and then I used the dirtycow exploit to flash TWRP. All's good now on XenonHD.
so I thought I had a grasp on the unlocking rooting myself. I was getting the error in lgup where it doesn't recognize my device at all. I unlocked the oem and it did its own flash afterwards then I had to go and reset unknown sources. then I tried to do the lg up flash assuming all I needed from my 20i was the v10d arb01 may 23, I picked the upgrade and in the middle of it it failed. then it rolled back. so I tried it several more times in lgup and it failed so I tried the arb 01 march 4 with full root and it failed.
Edit: okay lI found uppercut and it reconnected me to LGUP then I used the flashable 20a file and that patched me right up. But no root, I can do a 1 click now I guess but what about a flashable twrp or can I just install it like the old cwm or x-parts? where to now? do I try the 10d one with root? I'm really tired of looking and blindly downloading tot and kdz files hoping they work? My main goal is to slap RR remix on this for anyone that would give me a hand
