[Q] [HELP] Unrooting LG G3 V10l

Hi guys i'm new to all this soo here is what i did.
I recently rooted my lg g3 V10l-EUR-XX and now i want to unroot it ... but the problem is that i found only the kdz file without the dll file ...
Can you please help me find it or if it's possible to downgrade it from v10l ? Sorry if i said something strange or impossible but i'm a complete newbie with the roots and stuff

If you download the LG PC Suite and click on "Restore Upgrade errors" it should reflash the current version, but i'm not sure as it might download the latest which is lollipop.
You could also flash your KDZ file using the LG Flash Tool. Without the need for a DLL file.

Because i have been reading a lot of post this week and everything messed up. That's why i didn't see that the LG Flash Tool doesn't require .dll file. I just brought my LG to stock and everything is fine ... Thank you for ''enlighting'' me ! :good:

In fact i have one more question ... probably a silly one but still. When the LG was still rooted i got an update for v20e i think but i didn't install it because i assumed that it will be bad and it will ''brick'' my phone ... and now when it's stock i don't have that update. What should i do or it is just a matter of time the update to show up ?

Since you device in now unrooted there will be no problem in updating. The update may show up some time, but you can always flash it if you want to.
NOTE: Lollipop CAN NOT be rooted.

and this can take between an hour and several days, so either wait for it or flash as suggested.

yes, by flashing a kdz ontop of it

tnks, im new to lg, is kdz the equivalent to touchwiz? i dont really want to flash different roms, rather stay on stock,

no kdz is the system file that contains all the system partitons
like how sony compiles their system updates in ftf format

[Q] Prepare for transition: 10L -> 20E & back.

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.

Help, I rooted my phone and I get a warning everytime i open it

Hello
So after foolishly updating to Marshmellow and discovering that all my apps no longer update in the background, i flashed my device to the LG G4 V10D-226-01 software version, the 10D Europe Open from the LG g4 "Go back to stock rom" thread.
Problem is, everytime i open my phone i get "Warning: Current version is not available for user. Cant find matched cust for Nt-code mcc/mnc[22601],subset[ff]. I have looked both on google and here and everything i found was for the G3 model and it involved using a "custom restore" image. but no explanation on how to use it, its not a KDZ so i cant flash it.
I'm pretty new to all this and everything i wanted was to go back to my Lollipop variant after seeing how Marshmellow behaved on my phone. (not auto updating my background apps).
I appreciate any help you guys provide.
Thanks

u cant downgrade once u go to Marshmallow. Its a security thing tht was updated in the latest firmware b4 Marshmallow came out. Ur gona hav to start all over again wth the latest KDZ b4 Marshmallow

I reformated into a Lollipop KDZ by flashing my ROM from the "Go back to stock" thread. Problem has appeared after i did that. I am currently on Lolipop v10D

nobody has any idea on how i can solve this issue?

download the kdz file for your device from here and flash it using LG UP here. all will be fine. i downgraded from MM to LP after MM had big battery drain. many people have downgraded using this method.

Flashing a EURO-xx rom on a AME-xx phone?

Hello
I'm currently on V10o-AME-xx (middle east) using an unlocked D855. I'm currently rooted and only have xposed on there, no custom recovery. What I want to do is remove the root and get a fresh new phone while still being on kitkat. I started looking around and found this method.
http://forum.xda-developers.com/showthread.php?t=2785089
However, the problem is I cannot find my phone phone's version in the firmware database there or anywhere really. Does anyone know where can I find it? If not, what'll happen if I flash the european one on my phone?
I found this thread where a user posted the link to the V10o. Not sure if it's the middle eastern version though. This is what he wrote, "Maybe one off the devs can do a flashable zip out of it", does that mean I cannot actually use it without modifying it somehow?
Maybe there's a way to extract my own KDZ from my phone?
Also, can I use the LGUP method to go from KK straight to MM, then from MM to KK normally? OR do I have to go through LP first? I noticed that post omits KK all together, probably because a lot of people got their phone with LP.
Thank you in advance.
