[Q] Downgrading to KK ROM - Three UK

Hi,
First time poster, long time trawler... thanks for all your info over the years.
I have a specific question about downgrading to KK from L on my branded Three Mobile UK.
I had rooted on KK and was loving it, everything was working great.
Three kept pushing the OTA at me, but because of root it wouldn't take.
Borrowed a PC (I run mac for work) to run LG Suite and (back up first) fix upgrade errors to unroot to take OTA.
For some reason it bricked it...it just sat on Firmware update at 0% forEVER. Wouldn't boot past it or recognise the device anymore.
Had to use the Mobile Support tool to bring it back to life... although this resulted in an upgrade to 5 anyway.
I'm really not a fan of L. Won't go into details as to why it sucks, but I want to go back to KK and root, and then wait for L to get root options.
I've never flashed a ROM before, however there's a ton of resources here so I will give it a go.
I want to go back to the exact same ROM that came with the device which I THINK I have tracked down to - D85510g_00 via
http://forum.xda-developers.com/showpost.php?p=53606494
and
http://www.mylgphones.com/lg-g3-firmware-checking-the-software-version-and-update-history
Can anyone confirm that would be the right one... Is there any reason why I shouldn't use this ROM?
I want to go with what works, and not risk bricking it by installing an unbranded ROM in case they've used some sort of security measure that I'm unaware of... or am I just being a noob?
TL : DR
ON Lpop, want KK back... downgrade to D85510g_00.kdz for 3 UK (Hutchinson) branded ROM - Correct?

Thanks for your reply. Will borrow a PC again and give it a whirl tonight.
I have the KDZ file, USB drivers and LG Flash tool already downloaded... and intend on following this guide - http://forum.xda-developers.com/showthread.php?t=2785089
I have seen in the second method mentioned in that guide - TOTs and DLLs, could you confirm that these are different paths to the same goal? Either I need KDZ or I need TOT & DLL... but I don't need KDZ and TOT and DLL? Have I understood that correctly?

Not sure which firmware versions I can install on my G4

I wonder if someone nice can help me understand a little better re what version's of firmware I can install on my G4
My G4 is Model LG-H815 I noticed the box has TWN on it so it most likely came from Taiwan (I purchased it on ebay from Kogan) and I am in Australia on Telstra network.
Is mine classed as the international version then?
It came with V10b-TWN-XX installed on it.
After reading another thread I yesterday flashed it using version from Poland 10D H81510.kdz using the KDZ flash LG Flash Tool 2014 method
It is running fine on the above and doing that flash removed the Chinese keyboard and stuff so that was good.
I noticed after checking I am still vulnerable to the Stagefright issue so would like to find a newer rom that has this issue fixed if possible.
I am confused about all the versions of ROM's going around and was hoping someone could give me an overview of the various one and pros and cons against using them on my particular G4.
I dont mind doing a complete reinstall so keeping current data isn't important.
I would also like to root the rom (mainly so I can adjust the DPI) So some help on rooting the latest ROM would also be appreciated.
Thanks for your help.

I don't know for sure, but you could try cyanogenmod, it should have a working installerar that helps you (depends on if they made the installer for your devices)
Sent from my LG-D722 using XDA Free mobile app

If your model in the model report is H815, then you are safe to flash the unbranded European kdz. As I have said in other topics, as long as it's not H815T, or H815P or whatever, then it's fine to flash EU kdz on it.

Ok then that great - tks
So whats the latest version rom out at the moment I could use and how do I root after flashing it?
Many thanks for your help.

The latest version that I know of is the European Open 10E.
After you flash that one using the kdz flashing method, you can check around for the rooted 10e img and flash it using low effort root method.

OK all done - all working fine..
One small issue one of the apps I use "Netatmo" will no longer install "This item is not compatible with your system" error when trying to install from the G4 or via GooglePlay on PC..
Must be some sort of region thing perhaps?
And I get "Warning current version is not avalible for user ....." error on boot up.
Any idea how to get around that?
Thanks again.

AFAIK no way to get rid of that, but it doesn't affect any usability of the phone, so I just learn to ignore it.

Yes there is a way to get rid of it, as long as you have root. I don't know the specifics but I read it in one of the threads. Just search the error I'm sure you'll find it.

I'm from uk and have flashed many kdz from different regions without any problems. Currently I am on 20w-eur the latest for uk is 20u.I have flashed from Poland and Spain before without any issues although I would recommend flashing kdz roms near to your country ie if you are in the UK not to flash a China kdz but technically I think you can flash any.
Remember to read the LG Fashtool guide thoroughly and do not disconnect until your phone as thoroughly flashed and rebooted.

I am from Romania but the phone is unlocked.
I have a little bug which really annoys me: When i select swype to unlock the phone, after i swype, there is a little lag, around 0,5-1 second, before the virtual menu buttons appear. However, if i select PIN to unlock the phone, this lag doesn't appear and the virtual menu buttons appear instantly.
I was wondering if there is something to do with my rom, V20t, and i wanted to try a different one, but i want to be sure it is safe because this is my first LG and my first experience with flashing roms. I am full stock, not even rooted.
Thank you.

Nothing is 100% safe but if you want the latest firmware without too much technical knowledge then using flashtool is probably the best way to go.
Just follow the instructions on how to use flashtool and make sure you understand everything and you will be ok.Just remember don't unplug your phone from the computer until it as totally flashed and rebooted and you should be fine.
I have used flashtool many times and not had any problems you could always wait for the Android M update ota but that may not be until after Christmas.

Invalid Software Package & Rooting questions

Hello XDA,
I got an LG G4 gifted, and as one of the first things I want to do is to root it. However I seem to have quite some difficulties with it.
My previous phone was a Nexus 4, and I simply rooted with 'Nexus Root Toolkit'.
For this phone there appears to be many, different ways to do that.
First thing I need to be sure is what exact model my G4 is.
In 'Phone Info > Hardware' it simply says H815. In the LG Mobile Support Tool it says H815B (Which gives no result on Google). The phone is from Germany if it helps.
Second thing is that it says I can update to SW version v10c. But when I download the update, it simply throws a 'Invalid Software Package' error at the end of it. The LG Mobile Support Tool says I have no update avalaible instead.
Third thing is that I don't remember if I have to unlock the bootloader to root my phone (did that only once on my N4, forgot if it's needed). If yes, can somebody link me to the appropriate page? (I've read around LG itself released a tool to unlock that?) (Also, I will loose all my data IIRC?)
Last thing, obviously, the most appropriate Root guide for my model. I've read many of them, one requires you to have linux on your PC (Which is a nope), others mentions '10c' (which I suppose is the update I'm unable to get). So far I got myself only very confused. (Root voids warranty? IIRC LG still covers phone with root?)
Thanks in advanced for your help
EDIT: Currently trying with LG Bridge software, seems to work and says my phone is H81520A (So I suppose the part after the device code is the 'SW Version' ?).
EDIT2: Apparently updating with that software worked. Now on v10c (Marshmallow 6.0 - Unless there are other updates waiting)

You can indentify your model by adding your IMEI to the following link: csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=
(look for the field buyer)
The unlock process is described in this thread.
But don't fash SuperSu If you are on Android 6.0, because it will fail to boot. First flash an custom kernel (like this) and then SuperSu.
If you're unable to unlock the bootloader, then there is no possibilty to get root on Android 6.0.

Thanks. It says DEU at the buyer line.
D(eutschland)EU(Europe) I suppose.
And thanks for the link. In the kernel page it says 'download 20a or 20b? What's that number? So I need a Kernel that inclused SuperSU as flashing it on its own will cause that problem in few words?
What about this? http://forum.xda-developers.com/g4/development/repack-kernel-root-android-6-0-t3232387
From what it seems, it's a custom kernel + root. Would I still need to unlock the bootloader? Perhaps using the 'LG Site' section from the thread you linked (http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241)?

The software versions are quite strange on lg phones. 20A was the first test version that was released in poland. The official version now is 20B but phones with a branding have different versions. For example my phone has a vodafone branding and has the version 20A, but it is the same as unbranded 20B. (so it's really strange some times)
Look what is written in the settings under software information.
You need to unlock your bootloader to root your phone on Android 6.0 (this will void your warranty). You're right, it seems that SuperSu is already integrated in the kernel so you don't have flash SuperSu separately. But i am not complete sure because i didn't unlock my bootloader.

Thanks a lot for your help.
I managed to unlock the bootloader, but then I fuffed up..
Accidentally installed SuperSU (Was following that guide, and forgot about what you said).
Now the phone is kinda stuck at the very start, with the LG Logo (Not the animated one, the very first one)...
I'm hopeless now? D:
EDIT
I'm trying to recover with this video (LG G4 KDZ Firmware Restore Unbrick and unroot tutorial -- can't post links yet..)
But the LGFlashTool throws an error at 9% (imgur link -- can't post them fully yet) imgurDOTcom/pR1NYHD
EDIT2
Apparently I'm trying to flash a KDZ with Android 5.x while I'm on 6.0, which is a no. Will try with a 6.0 KDZ if I find one...
Else I hope for LG assistance (Or Amazon support, since the phone is less than 1 week old)
EDIT3
No luck with KDZ, but now the phone is going past to the animated logo, but being stuck there..
EDIT4
This saved me: http://forum.xda-developers.com/showpost.php?p=63843511&postcount=146
Worked perfectly, my phone is back and fully working

Sorry, i wasn't online the last couple of hours, but i'm glad that all worked out for you

No problem, you were of great help.
I'm currently not trying to root until there is a safe procedure to do so for 6.0

I don't think that there will be an easier option in the near future. You can make a backup with twrp and try to flash the kernel again.

Mmm, currently I have only the bootloader unlocked. No root, no custom recovery.
I don't feel like to play more with these stuff in the near future, after I nearly bricked the G4
Perhaps later on.

G3-D855 trying to upgrade from 4.4.2, but it refuses no matter what.

Hi all.
I bought a used LG G3, where the guy said this phone had been used to pass around reviewers, so I don't know if this has any factor as to why I'm having issues.
So, issue is, I'm on 4.4.2 atm, and want to upgrade to at least 5, and possibly 6 if this is possible (which it seems to be from what I've seen around the web.) I tried to do it via the phone first, through the built-in update center (current version is V10g-EUR-XX) It sees there is an update for the phone, which I then select to download and install. It then tells me it will download it, and shows the object under my notifications. But then it simply says Cannot download, and just stalls at this point. I've tried both options with wifi only, and over 2g/3g as well.
(At this point I added some screenshots I took, but can't add them, as external links are not allowed for the first 10 posts)
I then tried to go through the LG PC suite, installed the USB drivers etc. When checking for updates, it simply says "Cannot Proceed Upgrade. LG PC Suite upgrades unavailable on this phone."
Where do I go from here? Can I manually update it through the flashtool 2014, or am I looking at rooting this phone, to get be able to upgrade it?
In advance, thank you for your help.
Best Regards,
Dozer.
