Remove bump(twrp)+ unroot - G3 Q&A, Help & Troubleshooting

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 ?

Dear all,
Its really embarrassing but i have to admit that i have no idea about anything related to rooting or updating phone through flash files etc.
I have just purchased LG optimus G Pro online which is Korean version F240K (Olleh carrier) the phone is till in transit however i am not sure how can i update the phone. Since its unlocked and i am from India i don't know if OTA can be possible. I was told by seller that i can root the phone. But i don't really know what is rooting how its works and how its done. After rooting what has to be done etc i have no idea as i have never done this. I do know that if i do something wrong in rooting or flashing( these terms i have just heard from some people and on Google) my phone can be dead and cant be recovered.
I may be asking too much here but can anyone here help me specifically to update this device and help me to use all that is required?? I will be highly grateful if that can be done please.
Also can anyone tell me if there is FAKE LG g pro available in markets?? Cos i heard there are clones available in Korean markets for phones like Samsung hence i want to be sure about this

If u like to update your phone with stock kitkat, do not root or use any custom recovery. Use the usual lg software to pet it find updates. If it still doesnt find it, then you should download the lg firmware kdz file and flash it with lgflashtools.
Or if you are going to have custom roms installed, u have to root your phone and install freegee to have a custom recovery installed. After this u can install a custom rom designed for your phone model and try them out.

Hey, I am also from Sweden. Not so sure about the root counter, but I have had my G3 on service and they didnt mention anything about modified software. I just flashed a stock KDZ with LG flashtool which seemed to remove all signs of root, there are guides for LG flashtool here on the forums. I suppose you have the D855 model? Then any international D855 KDZ should work just fine, I havent had any trouble connecting to Telia with any international D855 modem yet.
About ROM's, its kinda hard to recommend a ROM since I have no idea what you are looking for. The bumped AOSP ROM's are still being worked out and can have some bugs, if you are looking for a stable close to stock ROM with some minor modifications I would recommend CloudyG3, or if you are interested in the latest news you could try out the pre-rooted Lollipop ROM (Havent had the chance to try that one yet, so cant really say anything about it)

How to root my LG G3 (i have searched already!)

Hi guys,
I might get flamed, I might not.
I have searched on google on how to root my LG G3. I have used towelroot and it says something like it isn't compatible. I used stump root and it says its patched. I used purple drake and I manage to find my device but the error comes up about vulnerability.
Luckily with PDrake, I found my software version as I have been seeing 10f 10e etc everywhere and it seems mine is a v20f.
Into google it went and the search it very minimal on answers.
Do I have to rollback the software to a kit kat version in order to root??? Is there any other way or more importantly is it a safe way?
All I really wanted to do was change some of the UI sounds and I cant access the system folder without a root!
P.S. Is there up to date, guide on how to roll back?
Thanks!
Yes, you have to go back to kitkat, then I used IOroot and then install twrp via Bump

Dammit, so downgrading it is.. <_< Been searching and you have to download custom ROMs? They are labelled with 10g/10f, are these related to the version of the phone?
Sorry, not clued up on all the jargon/acrynoms.

Ok nice, so D855 16GB from UK and unbranded ?
This KDZ should work. It will bring you to V10A, so Kitkat, and after that you can root.
If you have issues downgrading, I suggest you ask in the other thread, it is especially for this step.
Good luck.
BTW: doing that will erase all your data on your phone.

Again im not sure if it is branded or not. Its an LG G3, is LG not the brand? lol Sorry!
Thanks for the link, clicked it in another tab and doesn't seem to be working but ill figure it out.
So doing this process wipes my phone? So much for just wanting custom UI sounds :haha: No way around the phone wiping? I mean most of my stuff is backed on google+ but its just tiresome considering I have just put everything on there already with the phone being new..........
Thanks again.

What I mean by branded is that you might have some Vodaphone software on it or from an other carrier. Unbranded means it's a pure LG phone unmodified by the carrier.
LL can't be rooted so you have to downgrade to KK.
For doing so you need to factory reset your phone using a KDZ or a TOT file, and there is no way around wiping the thing doing that.
Yeah that's a lot to modify a sound, but eh that's the deal as of now. And mind that if you downgrade to KK and root, you can't get back to LL if you are rooted. (Well you can but your phone will become a brick)
If you want a rooted LL, you need a custom rom like CloudyG3 for example.
Cheers for reply, already hit that thanks button.
Seems a lot for custom UI sounds, think ill wait until someone develops something. In the mean time I will continue to search for the ability to mod the system audio file without a root
Sorry to hijack, but can I confirm that the way to go from stock lollipop to rooted lollipop is to downgrade to Kitkat using the links above, then root, then install a rooted Lollipop rom?

Yes. LL has been rooted, but it´s way more complicated than previous versions of Android. You can wait, but it could be weeks, months or years for an universal safe and stable method
And the G3's locked bootloader isn't helping too....

H815 TWN, differences from EU?

I am certain my G4 is TWN, from the box and the software version. But what are the actual differences to the European H815? Specifically, can I flash European KDZs or use the EU command for flashing a rooted /system image?
Code:
dd if=/data/media/0/system.rooted.H81510c-EU.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
Thanks
I have a the TWN version too damn it. - that's what happens when you buy from a global vendor over the internet .
Good news is that you can flash the EU rooted system image. I did and it worked fine.
Bad news is that you can't unlock the boot loader (yet), which means no TWRP or custom roms and flashing a stock Marshmallow leaves you without root and no way to downgrade.
Cheers
BTW I don't know of any differences between the EU and TWN devices other than the version coding - to me it just seems to be a way for LG to control their different markets.
Thank you for this. I do not want to unlock it just yet, since I bought it from a local vendor and I have a 2 year warranty with them. I see there is already a rooted image for v10d TWN, so I will flash that soon (are you sure the parameters for the dd command are the same?).
Sidenote, it would be nice if we could compile our own KDZs and make rooted ones.

I can't really comment on the all the parameters in that command string except to say that it's one I used and it worked well. Whether those numbers would need to be modified for the 10D image or not I can't say - I would suggest you ask the author of that original rooting thread.
BTW you can't unlock the bootloader on the TWN version just now in any case. I tried the official method over the weekend and was told the TWN version was not supported. There's unofficial unlock method available for any G4 variant yet either but people are working on it.

Probably the parameters aren't different between firmware images, because they depend on the partition table of the device.

I did the same thing, buying online and getting stuck with TWN. I came from a GS6 and was thinking "I'll wack an AOSP ROM on the G4 and I'll have the perfect phone". Now I'll probably never buy another LG even though I actually like the G4 but when we pay close to $1k for a phone we should be able to do what we like with it!
There is a thread for stock marshmallow which you can install with flash fire but there's no root available with that option just now.

Sorry. Missed this while I was away.
The thread I'm talking about is http://forum.xda-developers.com/g4/development/stock-h815-20a-stock-rom-t3233049
BUT be warned you will lose root !!. So far as I know just now there is no way to get root on stock MM without an unlocked bootloader. This may have changed inthe last couple of days - you'll need to read around the forum.
ALSO there is no sure way back to L is you decide you can't live without root (I certainly couldn't so I'm waiting for further developments). I think I read that someone here more-or-less accidentally managed to recover back to L but I didn't really have time to take in all the details so futher reading needed if you want to take the risk.

Buidprop editor - allows altering a number of settings but especially DPI
Greenify advanced functions
Amplify
Better Battery Stats
Flashfire
Busybox

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.

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...
