Answering for the team so if the guys want to correct me, feel free, just attempting to head off more distracting lines of "not" frequently asked questions. THANKS FELLAS!
1. YES, this is simply a method of gaining root, nothing more, nothing less. Your FOTA will likely fail OR worse due to a) being rooted and failing checks or b) system changes you may or may not make after you ROOT but this is a "Method TO ROOT" so again, nothing more, nothing less. (Question is out of scope)
2. NO, why would you even want to get an updated root method app that you are supposed to uninstall after you have rooted? (Question doesn't really make much sense)
3. NO CLUE and out of scope, this is a "Method TO ROOT", nothing more, nothing less.
4. Probably but if you want to help, you tell @jcase but it's out of scope and as an exploit creator, not really his/the teams deal or worry.
5. Out of scope, this is a "Method TO ROOT", nothing more, nothing less.
Good day to ya... :good:

for any G3 model , but right now D855

Remove bump(twrp)+ unroot

Hi guys
I installed [ROM] AndroidNow HD 1.7 G3 D855 [V10L/support ART] on my LG G3 via BUMP(TWRP)
Now I want to know if there is any way to install STOCK ROM back(this one which was on phone when I get it) If answer is yes, where do I get flash file for it?
Also can I unroot and remove BUMP ? I'm asking because of warranty...Thank you

you have NO warranty as you have flashed a custom rom/recovery and rooted (depending on country and/or fault with device) also use the search button as this has already been covered plenty.

so what? does he have warranty or not?
you don`t know the fault and you don`t know the warranty restrictions of slovenia (europe) in this case.
please tell only facts about warranty and no assumptions. thanks.

technically you void the warranty by modifying the phone, however, there are arguments especially in the EU that a software fault cannot breach the warranty for faulty hardware etc.
also if you flash back to stock they have no way of knowing what you did, also from experience they tend to not care anyway.

Thank you guys for all your answers to my question.
Specially to the guy , who gave me the link to the KDZ image file and FLASH tool.
I will try to restore my LG G3 back to STOCK ROM because of update to android L(Lolipop).

If you are returning to stock only for the Lollipop update you might want to just wait because I'm sure we'll have a working Bump'd port by the time LG starts rolling out the update near the end of this year. That being said, you may still receive the update before us, but Autoprime and TheCubed have warned us not to take OTA updates because Qualcomm is rolling out its anti-rollback updates soon that may prevent you from ever unlocking this phone again and may make you lose root for a long time. I'm sure that LG is working on patching Bump in the 5.0 update so just be warned that you may never get a custom recovery on this phone again if you choose to take the official update. I am relying on the devs here to get us a Bump'd version so I can keep this beast free. That's just my two cents and it's your decision I just wanted to warn you about the risk. Have a good day man!

Thank you for your answer. Yes I heard about this news(qualcom,..) but I will go back to stock, after that I will ROOT my phone again and install BUMP. Do you have any information about when the BUMP tool will be released so cyanogenmod and other ROM's will come?
EDIT: Will this method also work: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html ?

Have you flashed the stock ROM onto your device? What bootloader version or stock ROM build did you have before you flashed the stock 7.0 build and took the update?
Downgrading to older stock firmware and then attempting to update is generally what caused that hard brick. If you can let us know what device/territory you had, we can try to point you to the right firmware to flash.

Yes I have flashed stock firmware on my device I remember downgrading to marshmallow then updating back to nougat then my device fully shut down it was all black. After this incident, i did what you would normally do and that was to use blank flash to at least get the bootloader back, as I did get the bootloader I could not use the boot options such as recovery mode. so I am basically stuck on the bootloader and can do nothing. My device is an addison XT1635-02 and before I flashed nougat ota I had the marshmallow December security update.

I also believe my device is hard bricked as I cant access boot options at all it just keeps boot looping once I try to access a boot option. also is it normal for my bootloader to say that my software status is modified because I think after you flash blank flash your software status modified. finally, I have been trying to flash stock firmware but for some reason, gpt and bootloader.img always fail to flash. Thanks for the reply I hope you can help.

this is a dumb question but do you think that it is possible to get out of a hard brick without sending it to a moto service center.

Should be possible, there's a thread here on how to help repair your bootloader, which has a link for some updated firmware for you to try : https://forum.xda-developers.com/moto-z-play/how-to/guide-unbrick-moto-z-play-t3618492/page33
I would recommend confirming it's for your device. You are likely getting the errors you mentioned as the bootloader and GPT are perhaps to old for your repaired bootloader and so are not accepted. Which blank flash did you use to repair your device? I'd just like to check you've used the correct blankflash before proceeding. Also, which GPT/bootloader were you trying to flash that gave you the errors?
I think the service centre could charge you up to 70-80 % of the original cost for a new motherboard if this can't be resolved.

ok the thing is I am certain I used the wrong blank flash zip therefore meaning that I flashed the wrong things this is probably why I'm boot looping do you have any idea how to revert the changes of blank flash so I can flash the propper blank flash.

As far as I know, blankflashes are CPU specific, and may also be device specific, though we've had some success using a Moto Z2 play blankflash to rescue Moto Z Play devices that are hard bricked. There's some more info here https://forum.xda-developers.com/moto-z-play/how-to/guide-unbrick-moto-z-play-t3618492/page19 and here https://forum.xda-developers.com/showpost.php?p=73474192&postcount=249
Which blank flash did you use? Also, which July security patch firmware are you flashing? sounds like your need 7.0 or 7.1.1 firmware to proceed. That firmware link would take you up to 7.1.1, yes, but I would advise not to downgrade in future.
Also, please edit your posts rather than making new replies. I understand you're wanting to get your device fixed without paying a lot of money to fix it, give us time to respond.

I just checked its all good i was using the right one. it appears that if you use blank flash, in general, it will modify your software status. I will flash that stock rom I just hope it would work and yes i was flashing the july marshmallow 6.0.1 update and it had no effect on my phone what so ever lets hope this 7.1.1 does. also sorry for all these replies I am in desperate need for my phone and I'm not thinking straight

If your device was ever on stock Nougat (7.0 or 7.1.1), then flashing that marshmallow ROM won't likely work in repairing your bootloader. You need a firmware that is the same or newer than the latest firmware your device had. Downgrading stock firmware does not usually downgrade your bootloader, hence the corruption and need to have same or newer firmware to repair. Your bootloader would otherwise reject old firmware via preflash validation errors.
Hopefully the 7.1.1 firmware will help fix things. You will lose data however in the process of flashing your device, so hopefully you have backups.

Does the 7x have a/b partitions?

I want to install magisk, but I still want to be able to take ota updates. I also want to keep the stock recovery if possible. Is there a good way to do this, or will I have to flash TWRP?
Edit: it looks like magisk v15 is bricking 7x's. Should I wait a bit before I try to install it?

I Do Believe You Need To Be Rooted To Install Magisk...
And to root you have to Unlock your Bootloader.
Your device will Reject Any and All O.T.A.'s with an Unsecure (A.K.A. Unlocked) Bootloader.
That's why you get that hidious *Warning!* message everytime you reboot.. your device knows it's unsecured.
You can sideload all the upcoming O.T.A.'s when someone makes them available.. I kinda doubt that is going to be on day one though.
The Nice thing about those of you that are rooting is, you can just pay the $18.00 bucks and bring your phone back to stock with that D.C. tool that is being discussed in the Q & A.. I assume it works on all variants ?
Anyway.. good luck to you if you do decide to go ahead and unlock that Bootloader.

Magisk is a rooting method, I know from experience that you don't already have to have a rooted phone. Also magisk v14 added a feature where you could patch the boot image and flash it via adb.
What's this "D.C. tool"? It sound interesting

You Are 100% Correct...
You're conversing with an old "SuperSu" guy here.. I totally forgot mag's is a rooter like Su.
But you still have to Unlock that loader to make it happen.. You are not going to get any O.T.A.'s
I know Magisk can hide root for things like netflix... But not to recieve Vendor Updates.. unless things have changed drasticly.. please correct me if I'm wrong..
But again.. sideloading is always an option.

When It Comes To Huawei.. I'm A Virgin...
Every other phone I've seen, the O.T.A. will notify you that your system has been "Modified" and will not attempt the update.
When you root.. Your Phone Becomes Insecure.. and is vernable to Malware, Virus, Hacks and god knows what else.
O.T.A.'s are Signed Packages.. They Ain't Going To Da Hood To Do Business...
Keep it locked if you want everything on day 1.. Then you can Root to your hearts content.

Note u definitely can't take OTA updates with Magisk installed. What's worse is the normal recovery doesn't have a proper update option so u'll have to use Huawei's Dload method which fails if u have tampered the system. Restoring to the stock ROM with a locked bootloader is also incredibly hard on Huawei/Honor devices.

Here's how to take ota updates with magisk. But what your saying is Huawei doesn't use recovery to update, they use proprietary methods that detect system modifications, right?

Thats not what I meant, Huawei does use the recovery to update like any other phone but their recovery doesn't let the user to sideload their own OTA files. U'll have to use their Dload method which is an absolute pain.
Further, the Magisk page u posted here mentions the system and vendor must not be modded so that means you can't use any app like Titanium Backup to block or uninstall apps since it tampers the system. Thats really annoying since the whole point of rooting is to modify the system. Also if u used TWRP then u will have a hard time trying to find the right recovery file corresponding to the firmware u r on. It is really hard for Honor devices since u'll have to download a large file and, using a tool on XDA, extract the images u need. IMO rooting this phone is worth it right now especially since it is new and will constantly be recieving OTAs in the coming months.

Will my H812 have less problems on lollipop?

This phone was given to me with marshmellow and im having the issue of not being able to update google play service among other things. the other issues im having might be the effect of the google play service. i just wanted to know if its worth attempting the downgrade on lollipop

Depending on the underlying issue, you may still encounter the Play Services issue on Lollipop as you have on Marshmallow.
First, see if you can work the issue out on your current system.
- Delete cache and Data on Play Services.
- reset app preferences and reset default apps in the menu in the Apps folder in Settings.
- delete your Google account and re-install it.
- use LGUP-NEW to reinstall your Marshmallow rom (H81220). Check out this site for some H812 stock roms:
https://lg-firmwares.com/lg-h812-firmwares/
scroll down to the firmwares list and install the correct stock kdz - carrier and version
You can downgrade to Lollipop (H81210) using LGUP-NEW - frankly I haven't noticed a lot of difference between them but does have the current advantage of being rootable. Some members report better battery life but you will lose some security updates.

- reset app preferences and reset default apps in the menu in the Apps folder in Settings.
- delete your Google account and re-install it.
- use LGUP-NEW to reinstall your Marshmallow rom (H81220). Check out this site for some H812 stock roms:
https://lg-firmwares.com/lg-h812-firmwares/
scroll down to the firmwares list and install the correct stock kdz - carrier and version
You can downgrade to Lollipop (H81210) using LGUP-NEW - frankly I haven't noticed a lot of difference between them but does have the current advantage of being rootable. Some members report better battery life but you will lose some security updates.

thanks for the reply, i actually did all of those things, including a factory reset. i will try to reinstall using lg up, maybe something in the stock image got corrupted? i learned that even if my phone boot loops, it wont be repaired as the serial number is out of range. so i might hold on to it until theres a good custom available

Yes, very possible that something got corrupted. Definitely try a re-install of your stock kdz with LGUP-NEW.
If you haven't checked out steadfasterX's bootloader unlock thread, you will have to in order to install any custom rom with some assurance of success:

You might as well get started now as it won't be long before he publishes. You will have to install his SALT program and create a backup before proceeding to unlock your bootloader preparatory to installing any custom rom:

IF, you'd actually read steadfasterX's thread and in particular his latest update (last page on the thread, currently) ... you would realize there had already been a proof of a successful unlock of an H812. I suspect your phone has been screwed up by somebody who didn't know what they were doing in the first place. No one has done more work in this area and had more successes than steadfasterX - good luck for waiting for a better way or getting much trying to sell it - check ebay and see the prices - LOL.

i didnt mean any disrespect, but the process is still in alpha state. this is my only phone currently so i dont want to risk bricking it. i have no reason for unlocking bootloader when there isnt enough rom support to justify doing so

The risk of bricking your phone has been minimized with steadfasterX's process - he has had a couple of successful unlocks of an H812 now and when he publishes it for the public, the risk will be minimized as much as it can be in any unlock case.
With respect to your phone not being recognized by LGUP-NEW. Make sure you have installed the LGMobileDriver_WHQL_Ver_4.2.0 available for download from the US LG site - the Windows driver will give you problems.

well i wouldnt care doing it if there was more rom support, i dont see a point in unlocking at this point. if im missing a benefit of unlocking right now, enlighten me. and thats the driver i already have installed

One benefit might be fixing your screwed up phone. Still didn't read the OP I guess as you were advised to in steadfasterX's bootloader unlock thread. Here's an idea ... before making summary judgements with little or no knowledge, perhaps you should check with the member that is sited in the "proof" for the H812 and post your questions there for the Roms he has tried. My understanding was that he was on Lineage for Nougat - the most popular downloaded custom rom for .... are you ready ... the H815/H811 - here's an idea ... why don't you check out ALL the roms that are for the H815/H811 in the Android Development section ... hmm ... really?

if you took 10 seconds, you would see i actually posed in that thread. and all they did was direct me to the OP which says nothing about lineageos working for h812, or that the h815/ or h811 roms work for this variant. all it says is that i can flash nougat based roms. so the thread isnt too helpful, im not sure why you think it is.

Hey man, i'm agreeing with you for most of this...
I'm also not going to risk anything until 10 H812 users have successfully unlocked bootloader and flashed a custom rom (one thats intended for h815 or h811) with steadfasterx's method. Maybe you can flash H815 custom roms once the bootloader is unlocked... but just to be safe, let's flash other stock carrier firmwares in the meantime...... in the end no matter what anyone says, its your phone at risk...
Member TheLatios381 and I were asking same question here:https://forum.xda-developers.com/g4...10-q2-2017-t3567402/post75742903#post75742903 because no answer to our question on steadfasterx's thread...
