Infos for possible G4 buyer - G4 Q&A, Help & Troubleshooting

Hi,
i'm from italy and i'm interested in G4 european model H815.
I read a lot in the forum, but i really have some doubts yet. Hope someone can clarify them.
- First, is touchscreen problem really and definitively fixed? In which fw version it was fixed? What is latest european fw version?
- Is it safe unlock bootloader? We could have warranty problem doing it?
- It would be my first LG device, so maybe this is a newbie question, but what "kdz" and "tot" stands for?
- Aside touchscreen problem (fixed?) and led problem (fixed?), which other problems i could expect with this device?
- Finally, is there already a custom rom that is better (in performance, fixes etc.) than orginal's one?
Thanks for anyone help me to understand.

I'd actually like the answer to these questions as well, being a Samsung fanboy, this is my first LG device.

I never have any problem with touchscreen.
There's official bootloader unlock directly from LG for h815 but it will void your warranty.
kdz and tot refer to factory image
Volume over earphone is pretty low. Can be remedied with viper4android.
I'd just get root with low effort root method and xposed running. There's rumor that unofficial bootloader unlock is possible only with original firmware (which will be lost once u receive ota and can't be restored).
Unofficial bootloader unlock is still a rumor

hi, i have the H815 European model too, also my wife
We never have any problem with the Touchscreen
From what i have read, if you unlock the BL via LG any Hardware defect is full covered by the warranty
but i think they can refuse a soft-bricked phone if they would (but i know LG as really cooperative for such problems)
you mean kdz - this is the LG Format for fimware releases, tot also but not oficially LG i think
i never needed or used tot files.
We have no problems with this phone here. this means not that there is no problem
There are custom rom's (and one or two kernel's) but Stock is faster for now (android M)
the 7 HD Rom is a stock based custom Rom wgich performs really good and delivers
a all in one soloution for the most people i think.

Thanks for answers, all clear.
But about touch problem i understand you didin't have it, but i would know if people having it have the problem now really fixed. Or it was only placebo effect for the last updates...

Custom ROMs on H815 TWN

Hi Guys,
Is there any way to install TWRP/Custom ROMs, on the H815 TWN variant? I tried today to unlock the bootloader today, but it still says not supported (screenshot attached), let me know if any one has found a way to Bump the kernel like on the old G2/G3 models.
Thanks everyone =D
I have exactly the same issue unfortunately. I'd be happy with ROOT for now.
I hope someone in the community can help us out.
EDIT: root (and downgrade from MM if needed) for TWN: http://forum.xda-developers.com/g4/help/twn-root-question-downgrade-root-t3328465
Sorry but it's not possible now. There's lots of us waiting for Bootloader to be unlocked for TWN model H815... but currently impossible.
Luckily we can still have Lollipop with root.

And luckily phones like the Nexus 6P or almost any other competitor allows for bootloader unlocking unlike LG.
So if you get pissed off enough, that's an option

Root for lgg4 us cellular lgus991

I'm kinda new at this and I need a little help with figuring out if I can actually root the lgg4 I bought? I've never bought anything from another variant other than the typical sprint, mobile etc.......so with that said......can I root this phone that's from us cellular? And if so can you point me in the right direction please.? My software information is lgus99120c
My model number is lgus991
Please help me
So far no root on MM. You will need to downgrade to LL with LGUP. Do research for your own model.
LG G4 us991 "unlocked"/ US Cellular
There is very little information on these G4 variations,
I am also struggling with this device. No real root method, mention of a couple custom and stock roms but no links,
Im running stock unrooted lollipop
Any real help would be greatly appreciated.

There is a brand new method for your device which can fully unlock it and so install even custom ROMs on it! Ofc rooting stock MM is no issue anymore for you then..
Just check out my PoC unlock thread in the g4 area!
This unlock method is based on ls991 (!!!!) firmware and so you should have no limitations. ("should" because no ls991 user tried it yet but it worked for other models where we had much higher risk of issues then with a ls991..)

[PETITION] LG K 10 BootLoader Unlock !

Man I even don't understand how is it possible to make from good device, piece of sh* *t.
But LG Know How
Why they spending time of developer's to remove root possibilities and after that adding LG modified bootloader unlock procedure.
I believe if LG DEVELOPER'S was not spending time for removing root possibilities and was Customizing BootLoader Unlock Process, everything was done until this moment, when users want to root the device, but it's impossible by Official Way.
All respected companies using stock android bootloader unlock procedure, like alkatel and others, or already made his costume BL unlock procedure, like Sony...
Only LG have this problem, like with my Old Optimus 3D, I needed to flash customs BootLoader, because stock one cannot be unlocked, simply to flash other staffs like costume Recovery or Kernel.
I sent a massage to LG and they suggested me to search on XDA, exactly not LG Support, LG FUN CLUB responded to my question
And it's A Class Smartphones manufacturer.
How it's possible to make ordinary smartphone with Quallcom Chipset, most respected company making Smartphones Chips.
They making the best CPU's, GPU's and modem chips in the Earth.
And after that Coming LG and removing fastboot mode...
Why?
Like I already said to LG: "It's very very bad decision to remove FASTBOOT Mode.
And I believe it's my last LG Device."
If I'm not wrong, Bernard Shaw said: "Those who appreciates Security more than Freedom, don't deserve nothing".
There is an online petition for unlocking bootloaders of LG K10 phones.
Please sign it, more people will sign it, more posibilities that LG will fix it!

Yes I also like very much design of this device.
And I have Original LG Quick Cover, with this protection it looks even better.
But bootloader unlock and rooting problems, for me personally, close all his strong sides ?

I found this information here.
I know that is not 100% possible, but it's 2016 model, it's not old device, so I think it will receive Nougat
And also I suggest to look at this Google Request.
Custome ROM!
Like any Smart Developr, before working with some device I'm checking if this device will receive android update!
Because if our LG K10 will receive Nougat Update, ALL MY WORK WITH MARSHMALLOW WILL BE LOST ?
My opinion.
I was thinking why LG K 10 with MEDIATEK Chipset can be rooted and with QUALCOM no opportunity to get root.
And it's showing LG Developer's incompetence.
From my own experience I know that is much more difficult work with MEDIATEK Devices, that's why I don't released Cris Kelo Rom for Samsung Galaxy Grand Neo.
I taken latest Samsung Firmware for this device, rooted it, fixed it to work with Xposed, but after that I got Rom Full of Small bugs.
And when I was fixing one bug I was getting one or sometimes two new bugs, finally I was mad with this Piece of Mediatek technology and gifted it, after that I purchased this Piece of LG K10 Device…
What is the point?
For me it's normal that I can't make something, I'm not Professional Program Engineer, I'm Amateur Developer and LG Corporation Must Have Competent Program Engineer's, they must know how to make the same android on both Chipsets…

We absolutely need you here sir! I am waiting for Nougat from a long time! I worked a lot on this device. So I naturally made the decision of waiting for Nougat because this device is completely locked down and moreover I don't even the firmware file for my phone (LG K420DS, Same processor as LG K420N but 2 GB RAM).

Thanks
I also waiting for Nougat Update, then will try my best to make something.
But until update is released we must insist that LG must make Android Update With UNBLOCKABLE BOOTLOADER AND ACCESS TO FASTBOOT MODE.
It will be much better official way to root it and unlock bootloader than some our invents ?
After that it will be very easy to customize Kernel, Recovery and System ?
LG Must be joking ?
Was searching other time for root or unlock bootloader and decided to take a look how many LG devices can be officially unlocked bootloader.
There only 4 devices, Man it's ridiculous ?
OFFICIAL LG BOOTLOADER UNLOCK
It's some kind of joke, can I laf now?

LAF is the only way.
But if you are rooted then you are on the safe side.
Then we can root easily

Thanks all for you great development

Lg G7 firmware questions

well, thing is my device has a firmware from a carrier form mexico and i wanted to change it to get rid of those MANY apps it comes with. however, i ended up with some questions, i want a version that can give me OTA updates as they come out (this carrier takes a lot of time to realease updates) so as far as i could find the lm-g710em10b was a good option, but my model is a lm-g710awm, so...
1._ can i flash the g710em10b kdz on my g710awm model without having to worry about something in specific?
2._ Is that kdz version a good one or do you recomend another one for me?
3._ as far i know i do not need to unlock my bootloader to change my firmware, am i wrong?
hope you can help me, and thanks in advance hehe
