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.
Hi guys last month i have bought a lg g3 (d855) and its have the 4.4.2 kitkat version and when i try to update it is says that i have the latest version, and when i try to update it using lg pc suite its troubleshooting and cant update, please can someone help me how can i get the official lollipop update?? ☺☺
use http://forum.xda-developers.com/showthread.php?t=2797190 to upgrade.
should be able to get LP in some form from http://lg-firmware-rom.com/ by inputting your imei . it will be a .kdz file.
it will likely not be the most current version available for your device, but LP nonetheless.
best place to get up to date firmware is from http://forum.xda-developers.com/lg-g3/development/stock-t2961073
to use this link's software, you need to be rooted and have a custom recovery (twrp) installed, which is seamless. follow http://forum.xda-developers.com/lg-g3/development/root-root-lg-g3-easily-purpledrake-lite-t2821000 to root,
and install http://downloads.codefi.re/thecubed/lg_g3/bump/ via flashify. (make sure you choose your correlating mdoel, in this case d855)
following this, you will be able to make your way to LP
I'm trying to install the 10e update for the SEA version of H815 (over 10d which I rooted using this method). I defrosted any apps I froze in TB, did a full unroot in super SU, restored my pre-rooted image and did the OTA. The OTA failed to install giving an error code of 1123004. Then when it rebooted into android it said updates were not available due to suspected rooting.
I never had Xposed installed, and the only other thing I can think of is that I modified build.prop to enable write access to the external SD card. I'm re-installing the rooted image so I can revert that ...... but can anybody think of any other reason why this update might be failing to install on my phone? (incase this build.prop modification isn't it that is)
EDIT : oops, sorry. not build.prop .... platform.xml
EDIT x 2 : well, that wasnt it .... the change had been overwritten already. I assume it was by the flashing of my pre-rooted image - makes sense. Back to the drawing board - (or digging up kdz files)
If you type 277634#*# in the dailer, you'll get into a hidden menu. Poke around and there will be something that states whether root has been detected. Can't tell you how to get there, I'm on Marshmallow now and that doesn't have that hidden menu, at least not with 277634#*#.
If root was detected, you can still update but you'll have to use LG bridge on a Windows PC. And reroot.
I'm having almost the same problem on VS986, I can still try to update after reboot. Rooting is setting a flag on the device somewhere.
I don't know why they're blocking the update after unrooting besides just being spiteful.

2. Again tried to flash CM13, but process was aborted and phone bricked.
3. Flashed stock 4.4.2 again. Again no luck to write CM .
4. Flashed stock 5.0 v21a using lg flashtool. Again - if i want to flash CM - phone always bricked (error executing updater binary) . And now, even with stock 5.0 my phone data connection do not work (only wifi works)
Please help .... how to reflash my phone and get CM and back data connection??
Just tried flash 4.4.2 again. Flashed successfully, but still any data connection Tried update into 5.0 using phone software updater, but after few updaters it fails (invalid software package).
Today found, that data connection works perfectly if i set GSM/WCDMA . If LTE is selected, there are no data connection at all. Also, can't flash custom rom, phone always stuck at LG logo. Anybody can help so solve my problems?

I want to cite only the first point you described, because it's "abominable"!
Sorry for the harsh tones, but... the dialer issues obviously involved the Cyanogen rom, especially because you're using the first nightlies, often unstable.
Why you accused the official firmware (therefore no more existing since you replaced them) and decided to downgrade?
Then you've to known that important downgrades like Lollilop > KitKat may irreversibly corrupt system partitions like "efs", which make your device losing of IMEI code and mobile data!
Now the only thing you can do is updating your device by settings menu until you reach latest firmware (21A).
Since you've to manually confirm each updates (10A, 10E, 20A etc.), the process will take almost 1-2 hour.
When the update process in definitely completed, you can try to root device, install TWRP and flash latest CM13 nightly.
In case of other issues, try the quite stable CM 12.1, or the stock-based FulmicsRom.
If you continue to have troubles, do a CSE flash of 21A firmware and send your device to warranty.

Last time I connected my phone to LG mobile support, and it automaticallly updated my phone into newest official 21A firmware. IMEI - OK, data connection - still do not work when LTE is selected. So what i need to do now ? Try to root, install TWRP and flash CM 12.1 or FulmicsRom ?

So what's your problem when LTE is enabled?
Mobile data won't work or simply fallback to HDSPA?

Surely downgrading the entire firmware to the first release of KitKat broke the radio part of your device.
Probably if you downgraded to latest KitKat firmware (10h maybe, instead of 10a), LTE should works properly.
Have you encountered that connectivity issue even before flashing CM 13 (on official firmware)?

No, after flashing everything was fine. There is a way to reflash radio part without downgrading again ? Because when i spoted that data connection do not working, i downgraded firstly to 10a (no data connection), then i get 10h update - still no data connection. And after 10h update, my phone got another update, but showed that can't update because package is wrong of something. After that i flashed 21A what i have in my phone now.

Probably the mobile data issue was related to CM 13.
But when you downgraded to 10A, the radio part was really damaged.
As I said if you want to downgrade, always preger the "less old" firmware you need.
Like you, I downgraded in past to KitKat, but I never looked for 10A! I directly flashed 10H.
Sorry, but at this point I don't know what you have to do.
When you flashed 21A firmware, have you done a CSE flash instead of a normal one?
If not, do it.
If yes, you have to appeal to warranty without any problem, since your device has official firmware.

Yes, i did CSE flash. Ok, thank you. I think there are no more options than warranty.
In my country G3 still didn't receive the update to 6.0 OTA. I'll probably just upgrade it manually since i am tired of waiting.
If i manually update my D855 to 6.0 it will be able to receive 6.0.1 or others upgrades OTA in the future? The manual upgrade to 6.0 done by the LG flash tool is official?
Thanks in advance

If you flash kdz made for your phone you will recieve ota otherwise you won't. For receiving ota you have to flash kdz file made for your for your country's g3.
I strongly reccomend you to follow this thread to prevent hard brick: http://forum.xda-developers.com/showpost.php?p=64624353&postcount=3
Using the LG Flash Tool instead of the newer LGUP may cause serious troubles when flashing Marshmallow kdz files.
