Hi all - I received a brand new VS986 today with 5.1 installed (VS98611A specifically). I followed the UsU procedure to unlock the bootloader and installed Magisk.
Basically I'd like to either remove some of the bloatware on 5.1 / Lollipop or upgrade to 6 / Marshmallow. If I choose to upgrade, is there a recommended ROM to flash that won't undo the UsU I already performed? Can I use my existing SALT flash drive to manually disable / remove unwanted apps in download mode?
I had a custom ROM on my previous phone (Galaxy S5) but I think I'll stick with a vanilla ROM this time, at least for now, unless there's a highly recommended M/N/O custom ROM that doesn't have any glaring issues, and will be an easy upgrade path from my current Lollipop installation.
Thanks for any advice here.
After further research, it appears I did a no-no and applied UsU to a Lollipop bootloader. Now that that's done, is flashing a stock Nougat ROM (e.g. as described here) safe to do? Or should I go through the procedure listed in #20 of the FAQ from steadfasterX and try to flash elements from a MM .ndz file first? If so, I downloaded a VS98626A kdz file - should that work to pull the necessary MM boot files from?
Sorry for the newbie-ish questions, I'm just trying to avoid bricking my new phone.

Hi,
I have 855 (generic European version), V10L, rooted (using towel rooter), no TWRP, all OTA (since July 2014) installed automatically and seamlessly so far (keeping the root).
Today I got a prompt about V20E available upgrade.
I have LG PC Suite up-to-date backups of this device, and anyhow don't have anything that can't be restored, but in general prefer to not reconfigure everything manually.
Did nothing so far.
Questions:
Is it worth to move to V20E, is the version stable enough, worth to wait for V20F or whatever comes next ?
If I decide to proceed now, I want to be able to return to my current state (I do not need to fast switch between multiple roms, just way to get back V10L with my current configuration).
I prefer the way that allows me to keep receiving OTAs, and not to flush next updates manually.
After looking on the forums I though about the following workflows
First (without TWRP):
1. Create one more backup using LG PC Suite.
2. Unroot (just to be safe).
3. Accept OTA.
If I understand correctly I will loose root here, and it can not be restored (for now).
In case of need to restore:
1. Follow LG G3 Stock Firmware (Go Back to Stock) to flash D855 V10A. I hope after flushing it will receive 10L OTA ? Am I right, or I will be stuck with 10A ?
2. Restore my existing backup using LG PC Suite. If I do restore on V10A, will it bring me back to 10L ?
3. Reroot if needed.
Second, with TWRP:
1. Install TWRP.
2. Create full backup from inside TWRP.
3. Get prebumped Lollypop image (I see only V20C here. Where can I get more recent versions ?)
4. Install it and reroot if needed.
In this case I must reject upcoming OTA prompts and flash future prebumped images manually.
To restore
1. Restore full TWRP backup, and I'll get V10L with all my stuff preconfigured.
2. If at this step I want to get rid off TWRP, can I remove it somehow ? Will it restore the phone to the current state (rooted, V10L, able to get OTAs) ?
Sorry for multiple questions but currently the whole process looks a bit unclear for me.
Q: Is it worth to move to V20E, is the version stable enough, worth to wait for V20F or whatever comes next ?
A: No V20H got released today and its probably gonna be available in your region really soon
Note: If you do ever want to install stock lollipop please be aware LG backup cannot save the appdata of any system applications such as chrome etc etc
Q: Follow LG G3 Stock Firmware (Go Back to Stock) to flash D855 V10A. I hope after flushing it will receive 10L OTA ? Am I right, or I will be stuck with 10A ?
A: Check (http://lg-phone-firmware.com/index.php?id_mod=41) and download the v10 firmware the corrosponds with your country. If the firmware has a 6 in front of it its for the 16GB variant
Q: Where can I get more recent versions?
A: http://forum.xda-developers.com/lg-g3/development/stock-t2961073
Q: If at this step I want to get rid off TWRP, can I remove it somehow ? Will it restore the phone to the current state (rooted, V10L, able to get OTAs) ?
A: Yes, by flashing stock recovery.img. Restoring your TWRP backup will restore the phone to the current state

Thanks, but I am not sure about this one. What is the process ?
If I flash stock kdz it will remove TWRP, but I will not be able to restore TWRP backup (without TWRP), right ?
Is it possible to first restore TWRP backup, then flash "something" that will replace only TWRP, leaving android OS intact ?
Before saying anything, I would just like to give you a thank you for your post, it's very clear and pleasant to read. Looks like you also did a bit of research before asking so that is also very good :good:
So, I'm not gonna be able to help you a lot about the backup thing because I like to always start fresh when I change Rom or if I want to go back to stock. I backup my data manually and restore what I want to. Using a Google account it will automatically reinstall your apps, but you'll have to reconfigure them manually.
Anyway, I also got a D855, French variant A6FR. (A6 means 16GB) You can check what is the latest version that LG offers you by checking the link bellow. You just put your IMEI at the end and it will give you an XML with information about your phone, like your specific variant (German, UK, ... don't know where you are from) and the latest firmware available for your and a link to download it. For me it says D85520F_00 so it's LL version F.
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
So, you can go back to stock using the KDZ method and with the firmware LG offers you (removing root, revovery, ...), but as you probably now, LL is not rootable. To summarize, that is not really interesting unless you want a STOCK STOCK LL.
But you guessed right with the V10A. If you go back to stock with this version, it will remove the root, custom recovery and anything else you have, you will also end up with a completely stock G3, but KitKat G3. There is no obligation to use V10A, if you find a KDZ of a later version you can use it too. Of course we are talking here about V10something not V20 that is LL. Just make sure to use a version suitable to your phone (16/32GB).
Flashing that, LG will be happy and will let you do OTAs. So if you flash V10A, it will give you all the OTAs untill the latest available. So you can go V10A --> V10B --> V10C --> ...... --> V10L --> ..... --> Lollipop
You won't be stuck with V10A.
Now if you want a rooted LL, you will need to use a custom Rom. In the Dev section you can find for example GloudyG3 that is based on the stock LG rom with a few enhancements. It is currently based on V20F and will probably move to V20H which is a brand new version that went up like 2 days ago.
To summarize
KDZ with V10something allows you to go completely stock and give you official OTAs. It can be rooted.
KDZ with V20something works too and will give you OTAs, but is not rootable, so if you want a custom rom, you will have to downgrade to V10, root and install TWRP.
Flashing a KDZ always erase everything on your phone.
If you flash a custom rom, you won't have LG's OTAs so you won't have to worry about rejecting them.
Before doing anything crazy, backup your EFS (basically your IMEI partion) with TWRP and manually. Always nice to have several ways to do it.

I'm also interested in this answer. The only reason I haven't updated to (any ART) rom is because I'm unsure if I can just restore a Dalvik backup without issues. The only way I would attempt is with TWRP.
i tried doing by Flash tool and it gives error like 0000008
bring up the post!
Curious as well. I'd like to get root.
Windows user not sure how to do it on Mac/Linux
by MM to KK I assume you want to take the LG G3 D851 from android 6.x down to 4.x
here goes...
----
http://lgg3root.com/lg-g3-stock-factory-firmware/
http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/
use the LG Flash tool plus the two files, follow instructions on that second link step by step.
LGD851_20140611_LGFLASHv160.dll
LGD851AT-01-V10c-310-260-JUN-20-2014+0.tot
That takes you back to the 4.x kitkat stock ROM, not rooted or anything.
----------------
To go north from there back towards Lollipop or MM you can at this point use
http://www.download3k.com/Install-LG-Mobile-Support-Tool.html
B2CAppSetup.exe
Install it, will put an icon on your desktop, plug in your phone, open the app.
It's pretty much automatic, it updates the ROM from KK to Lolli, then if you hit "OK" it will update from Lolli to MM
- I just got both of these steps to work in the last 24 hours.
I'm still trying to find a valid "Root" method that doesn't ask me to install a funky ROM.
I went from a KK stock-rooted(TWRP 3.0) rom to the MM 6.0 Rom, realized I didn't really want to set everything up again, restored my KK backup. Only problem was I had to reflash the modem. That was a couple of days ago and the modem was the only issue.
I'm unsure about flashing a new/clean KK rom over a MM rom though.

I think I missed a step, in KitKat this phone needs a special command thrown at it so the memory cards will be read/write.
On the play store SDFix: KitKat Writeable MicroSD
I think that might be what I was missing last weekend. My phone is currently on MM but I can't root it with any method other than Kingroot and Kingroot is Bad News.
Yes. It's possible!.
Hello,
I'm currently using Z00AD -- ZE551ML -- 4GB/2.3GHz bought in Brazil.
In the system update option shows: ASUS_Z00A-2.20.40.198_20160930... as my current build. (Lollipop)
I'd like to know if the steps presented in this video /watch?v=MEF9S_VNtO0&t=377s are safe to follow. I'm not so sure about those LP/MM Blops I've been reading about, although I have some background in flashing another phone.
Is there anything I should know?
In the video the guy do TWRP backup, so, assuming I'm coming from stock, will it really work? (i.e.: I'll be able to restore to the stock version if necessary?)
Thanks in advance.
There are two threads about unlocking the BL and flashing twrp:
1: https://forum.xda-developers.com/zenfone2/general/tool-ze551mlmodder-t3458145
2: https://forum.xda-developers.com/zenfone2/general/root-install-xposed-marshmallow-6-0-1-t3456443
Both of these methods caused me to brick my ze551ml (2gb, 16 GB) running stock MM so be prepared to go through the process of unbricking the phone if necessary. My phone bricked, not because of those unlocking methods, but from something I must have done wrong.
If the custom ROM uses MM blobs, you'll have to be running an MM bootloader on the phone before installing the ROM.
Hello Dear Brothers,
I have tried so many ways to root my LG-G4 (LG-F500S) Korean Version . But every time i failed. Now I need help of a genius.

There may be a possibility to not only root your phone but also to install some custom rom versions, e.g., LineageOS Oreo, Pie.
However, it is first dependent on a couple of things:
1). You must be on stock Marshmallow - if you are on Nougat firmware now and cannot rollback to Marshmallow, you are out of luck.
2). Your ARB (Anti-RollBack) version must be 2 or lower. If your ARB version is 3 or higher, you are out of luck.
Your first step is to ascertain your current ARB version (using SALT) as that will help determine if and what version of Marshmallow you can rollback to safely (rolling back using LGUP-New, ONLY for this particular step ) and whether you are then able to proceed to unlock your bootloader.
If you can meet these requirements, then proceed to free your phone following the directions in this thread: [UNLOCK][UNOFFICIAL][G4] Unlock **ANY** LG G4 device with UsU. Read everything thoroughly there IF you are able to proceed and make sure you understand it fully and follow it exactly
If and when you've unlocked your bootloader with steadfasterX's brilliant UsU method ... then and only then you can proceed to install TWRP (custom recovery), and Magisk, for example (for root) and install a custom rom to upgrade your system to the latest security patches, etc.

You missed a point: "... if you are on Nougat firmware now and cannot rollback to Marshmallow ..."
So, the question now is "Can you rollback to Marshmallow?"
To determine if you can, use SALT that I linked in my first post and determine your ARB version - if it is above 2, i.e., 3 or higher, the answer is no. If it is 2 or lower, then the answer is possibly. Next, if you do not have a backup copy of your original Marshmallow kdz (firmware), then you will have to download one for your model and region. You can check this link if that is the case: https://lg-firmwares.com/lg-f500s-firmwares/#tab=firmwares or google for a match. You will have to download a kdz from there or wherever else you find one and check the ARB version, extracting it in SALT. If the ARB version is the same (and 2 or lower) in both your Nougat and the Marshmallow kdz you extracted, then you should be good to go to rollback to Marshmallow and then proceed to unofficially unlock your phone. Note: If it is lower (on the Marshmallow kdz vs your current Nougat firmware), you will hard brick your phone (you can go to a higher ARB version BUT it cannot be higher than 2).
Hello,
One of my kids SGS5 died so I borrowed an old (and unused) LG G4 H815 w/ Android 5.1 installed (and no available updates).
After a bit of mocking around, I managed to unlock the bootloader (via lg.com account) and somehow got TWRP v2.8.7 installed and after that, I managed to upgrade it all the way up to v3.0.1.
Any attempt to use any version above v3.0.1 fails (dtb not found).
When I try to install LOS of any version (14.1 / 15.0 or above), it throws an error (Error 7) and complaints about mismatched device ("this rom packages is for H815, this device is .").
I attempted to advance wipe the /data and /cache partitions to no avail.
I would imagine I need to a newer kernel and/or bootloader. Am I correct?
Any idea how I can upgrade any of them? Should I simply download a stock v6.0 ROM (of any region) and continue from there? Any preferable region (so I won't brick my device / relock my bootloader)?
Thanks.

FWIW,
ROM version: V10a-ISR-COM
Software version (according to LG Mobile Support tool): H81520P.
Hardware model: LG-G815
According to the LG Mobile Support tool (under Windows) upgrades are unavailable for this phone.

When you were able to unlock your device on the lg website use LGup to flash h815 20p stock (international/global). And yes you're right that a stock ROM upgrade is needed to flash newer TWRP and custom ROMs. v20p is the recommended version for all avail custom ROMs
Many thanks for the reply.
In the end I decided to risk it, download some random unlocked stock Marshmallow ROM via twrp v3.0.1.
Once done, I managed to upgrade TWRP to 3.0.2 (which previously failed to install) and then (after reboot) 3.2.3.
Once I upgrade twrp, it managed install LinageOS without issues.
Thanks again.
