flashed it on my TWN device
no bloatware or branded screens - so far so good, but can't see much of an improvement on battery live or anything else,
guess it's just a security update, containing Android security patch from April 2016

Working fine - Brazilian Retail H815P.
Was on V20B ¬¬
Updated to 20D and them installed this.
Only lost the APN, just reconfigured and that's fine.
Used 2014 LG Flash Tool.
Thank you very much.
No bloat, no visible bugs.
(Still waiting for 6.0.1 and better battery life, tho. This drive me nuts).
And why SO MUCH VARIANTS, LG? :(
Anyway, big thanks! :D

Im on 20D Eur
Do i need to wipe before 20G or do i just go upgrade in twrp ?
If You got kdz/tot files, then You should use LG Up instead of TWRP.
During flashing by LG Up You can update (keep current data) or refurbish (clean install).

I suggest to do this way:
1. nand full backup in TWRP (always do before big changes in OS)
2. soft backup of files, apps, sms, etc. (us Titanium Backup or any other backup app)
3. eject SD card
4. flash by LG Up in refurbish mode
5. inject TWRP, make root, switch off
6. insert SD card
7. login to Your google account and let to restore apps, contacts etc.
8. revert missing apps, setting and other thing from your soft backup

done :)

Is there an easy and quick way to generate a flashable zip from these kdz files?

Flash on my H815 SEA
Batt life is ok
SOT is 2 hours with 50% batt left
then charge the phone to 100% and next morning batt down to 65%
now i am going to reset the phone hope it will work

flash it as "refurbish".Make a backup before you flash because you will lose everything that you have

If I'm not rooted and bootloade it's steel locked, can I update using LG UP without losing my warranty (I'm stuck in January security patch)? Thanks!!

Few queries please.
- Is this the UK version of the update or at least 'English' (or does it not matter)?
- I have a rooted phone (using LG's official unlock) and TWRP - can I simply upgrade, using LG UP etc, and not lose my data?
I currently have H815 and 20d..

Right.. Took the plunge (after fully backing up my phone to my SD card - using LG bridge and Titanium backup..
First off. This image is v20H..
Using LG UP v1.14, i used the KDZ file (even though it says BIN in LG UP).
I selected to 'upgrade'..
Worked fine, now on v20h.
As expected, no root and no TWRP..
Next task.. Install TWRP and Re-Root it..

    It was written that its an update about 4g. It says now you can get faster speeds by combining 4g and wifi together. It was about 60 mb.
    After the update there is an icon of volte on the notification bar.
    I couldnt figure it out how to use wifi and 4g together, I didnt saw an option in everywhere.
    Explanation was in Turkish and it was funny.
    IT was something like this :
    (4.5 GIGA update. Artık 4.5G ve Wifi aynı anda kullanarak daha yuksek hızlar elde edebileceksiniz)

    Edit: Android Security Patch Date : 2016-04-01
