No-data loss upgrade possible ? - LG G6 Questions and Answers

Hi
I'm a long time Ericsson and Sony user, LG G6 is in fact the first LG mobile I'm using.
I'm a bit confused with the LG UP tool and Uppercut (when compared to Sony's Flashtool).
My phone is P4P region, however it was shipped to me with V20c-EUR-XX firmware (3.18.71 kernel, OPR1.170623.032, PHONE_SW_FULL_VERSION LGH870AT-00-V20c-EUR-XX-AUG-17-2018+0).
It doesn't have any Play (P4P) operator branding etc.
Unfortunately OTA upgrade nor LG Bridge are unable to upgrade it to latest firmware. lg-firmwares.com suggested that I should use uppercut and LG UP software to patch it.
Question 1:
Which firmware should I use ? I assume that as long as it already has a generic firmware, any EU open firmware should work. Is my assumption correct ?
Question 2:
When flashing the selected firmware, am I obliged to do a 'wipe' or can I upgrade it without loosing personal data on the phone ? If I can upgrade, which options should be selected in LG UP tool ?
Question 3: How reliable is Backup and Recovery tool when it comes to making a backup before flashing and restoring from this backup after the upgrade ? I'd like to move to at least v20i firmware.
Thanks in advance.

LG support tool said I have the latest version when restoring my D802T

Dear All,
I am trying to restore my bricked G2, but when I got to LG mobile support tool and select the language, it does NOT flash the KK kdz I downloaded, instead told me "Your device has the lastest software available from the LG mobile support tool. Please visit LG support website for more info..."
WHY???
FYI:
D802T Australia unlocked version, official 4.4.2 then rooted and installed Autorac which doesn't support D802T and stuck my phone at bootloop for good. Already downloaded the KK kdz. file and tools and followed this post"http://forum.xda-developers.com/showthread.php?t=2432476"

Found any solution to this? Have the same problem, it says i have the latest software even though the software it is showing on my phone (which my phone doesnt really have) is older than the KDZ that I am trying to flash. If I force it to upgrade, it starts but gives an error at 37% every time.

Use the LG Flash Tool instead.

Cannot receive OTA kitkat update

I have international LG G2 32gb with original jellybean... no root, no custom recovery.... the kitkat update never came. Whenever i check for system updates i get the message that i already use the latest system os. Tried 2 or 3 hard reset but no luck...
i dont want to update through lg software center because i read somewhere that doing that disables the LG RCT and in download mode the phone status is "rooted" hence you lose your warranty without doing anything wrong. I sent an email to LG Hellas but they do not acknowledge the problem.
Anyone has the same problem? any solutions?
thanks in advance guys!
oh man this happened only to me?
First let's try to find your original device firmware.
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=xxx
Replace xxx with your imei in the browser.
It give you the latest firmware version and the suffix(some capital letters). The suffix indicates the market region, my for example is from Baltic.
In the browser use " LG g2d80210a_00.kdz 32gb+suffix", 10a is for jg if you can't find a try b.
NOTE: never, never use a 16GBP firmware in a 32GBP device!!!
After you have kdz file, backup important data to a pc!
Flash with LG flash tools with cse option(it will wipe all the device). The phone will boot, skip the setup and make factory reset , boot again and update to kk by ota.
This way it will be full stock with unroot flag!
NOTE 2: the phone only will receive ota updates when there are available for that region (suffix) .

ok i get it, this means that before they sold me the phone they flashed it with european rom... now i have
d80210e-eur-xx
and the suffix i get is ASEABK
the solution is to flash jb for my phone region and then i will get the OTA.
Thanks a lot man!

[rom stock] [d855] 6.0 marshmallow - v30b - how to install in one click?

As long awaited update begins to be distributed in Poland but it seems to me. So if you're eager as I was, there is a very easy way to install and very simply and without losing its data, in short the MUST HAVE!
So instead of you enquiquinez Flashtool with the TWRP as you could see from everywhere (including xda where I got lost in the mass of information, links ...) and all the trimmings, it is very easily possible, installing marshmallow and a click!
In short, chat truce.
Tools​
.LG PCSuite (software designed by LG, no worries!) Downloadable here: http://www.lg.com/fr/support/pc-suite
.And that's all ! (minimum required, brain anyway)
Installation​
Obviously, it is essential that you are already on the Stock ROM and without ROOT without these two parameters, LG PCSuite will not detect new updates !!!
1- Select your model provides the link above and download LG PC Suite. Finally install it.
2- Once installed, open LG PC Suite and connect your PC to the LG G3
3- Make sure that the software detects your smartphone. If it is good, proceed to the next step. Otherwise, go on your G3, and verify that the MTP is selected for the software to access your smartphone data.
4- Now we are, bah left, tap "'Check Updates" on LG PCSuite on the home page (main page) and after two minutes the software will suggest D85530B - M ( or something similar if you were already on lollipop ). This update (MAJ) actually corresponds to Marshmallow, so it is gone, there is more to!
5- Install following information while selecting 'Do not make backup ", no worries, you will not lose any data! (Tested by myself) and wait while downloading (actually a .kdz file 1 , 2GB will be downloaded).
6- Finally, at the end of the download, you will see the G3 automatically entered into Download mode, before rebooting, etc ... then you start on Marshmallow . Wait a little first restart (personally, I had 75 applications that would update during the first startup.)
7- The last step in finalizing the installation, you will see on LG PCSuite "Continue upgrading" only continue doing that in the G3 arrives on the home page (the launcher what) then without restarted, it will solve the problem with the Google play services ...
8- So, just enjoy the new version!
For those who wish to have the file .kdz direct download, in case he would not receive the SHIFT PCSuite by LG, it is here

Thanks LG.

Can't update that way. Download the .kdz and use LG Flash tool 2014 and select cse mode (you will lose all data) so make a backup to PC or xternal SD card beforehand if you want to. You can download the .kdz from here XDA LG general thread LG G3 Android marshmallow discussions.
Hope this helps.

LG G6 Modding Issue

Hi everyone, I have a problem with my LG G6 H870 which concerns modding. I explain everything:
I have already modded my LG G6 in the past: root, custom roms, drivers and more, until I decided to return to the original system, the latest version, namely the v30b (in my case with the TIM brand (Italy).
Lately, with the desire to resume modding my device, I realize that LGUP does not work giving the following error: 0x81000302; and saying: Use the latest DLL. I confirm that I have changed versions of LGUP and also DLL, to no avail. The only version, of which I can't find the link, was one with a patch that allowed me to "force" the flashes. However, I don't want to use this latest version but permanently fix the problem. I think the problem lies in the last flash I made, in fact I find myself with an OEM (ORIGINAL) unlock key, which turns out to be wrong at the time of the flash via fastboot. Trying, when in doubt, to download another original key from the lgdeveloper site, I discover that the system replies with IMEI 0, thus understanding why the key was wrong. I would like to point out that I downloaded the current version (v30b TIM brand) from the LG-Firmwares website (with which I have never had any problem). I hope someone can help me to solve my problem permanently.

G3 Stuck in Firmware Mode after trying Stock Flash

Hi everybody, first time posting here, I'm quite new in flashing devices. I tried to flash a marshmallow stock Rom on my LG G3, but I changed the motherboard (old one had dead cpu) so I bought one on Aliexpress (was working great and running KitKat 4.4.2) but I tried to flash MM 6.0 because I had no available update on my system. Now the phone is stuck on the "Firmware Update" screen (can't do factory reset and all that stuff...). My problem is : because i've changed the MB I can't know what is the MB region (the original MB was D855 FRA, the new one's iMei tells me its a Canadian D852 and apparently it's not that either). I've tried dozens of Roms and used that with LG Flash Tool 2014, LG Flash Tool 2.0.1.6, KDZ Updater (LGUP doesn't recognize the device, etc...). But I think that the main problem is that I can't find precisely my MB model and region and so, can't have the right Stock Rom for my phone so flashing always ended up failing... If someone has some knowledge about this type of situation please could you help ?
