Do you happen to know a stock firmware link that works? Thank you!
[G4 Android Development] berndbb:
I fear this depends on the country for which you want to use it (or for which your device was produced)

Maybe you find here:

Models - LG-Firmwares.com

Free archive of LG firmwares. Comparison of features and reviews of all mobile devices. Quick download of updates for your device.

lg-firmwares.com

what you are looking for.

I found some firmwares on lg.com as well (e.g. on the US site of lg.com)

Is it possible to get Nougat in the KDZ file version with the new Bootloader? I have a situation where I currently have Nougat but I don't have TWRP Recovery.
[G4 Android Development] Ali Mirza:
Thanks a lot! I instead used "Refurbished" in LGUP, In no time I got Nougat. Phone feels new and snappy. No issues till now. The high contrast is just awesome in Themes. LG forever.
[G4 Android Development] Ahmed Helal:
working flawless with me specially the battery consumption i think its better, refurbished from 6.0.1 , using windows 10.

i thing some of u might had problems because of unlocked boot or root which i didn't have.

can i do the same with unlocked bootloader? dont wanna loose my files and apps
[G4 Android Development] anonymous1:
Hi guys,

None of the links point to H815 TWN.

Would any of these TOT files work for H815 TWN or SEA versions of the device? Has anyone tried on any of these devices?

I don't want to risk bricking my G4, as frustrated as I am without Nougat update. Any advice regarding this is much appreciated.

Thank you.
[G4 Android Development] tomaspe96:
Same question, will it work on a SEA device?

Thanks in advance!
[G4 Android Development] jkissane:
Great work, thanks a lot. LGUP keep failing for me at 9% with a myriad of different errors but in the end I just ran it again while the phone was still in download mode and it worked straight away. Did an upgrade from MM so all apps & data were preserved.
[G4 Android Development] tomaspe96:

Can some tell me which file I need for the flash?

If I can get root, I can disable big cores and hopefully extextend the life of this roulette wheel, I mean phone.
[G4 Android Development] goran_oh:
First you must tell us which model you use?you can't root with this rom.
[G4 Android Development] Diginix:
If I have unlocked bootloader and TWRP, is it then possible to root this ROM?
[G4 Android Development] dragankoz:
Ok then is there anything I can do with this phone?

LGH815 TWN (International) with Marshmellow V20e-TWN-XX. What are my options to either install custom rom or somehow get to root (whatever rom/firmware, don't care)
[G4 Android Development] goran_oh:
Sorry my friend but you can't root that phone,only option for you is to flash this room to get 7.0 because I have also that model and you can't unlocked the boatloder on 6.0 or 7.0 You have chance to root only if you downgrade to 5.1

You can disable big core without root,just edit the tot file with winhex i already did that
[G4 Android Development] dragankoz:
Hi can you point me in the right direction, LG makes it a nightmare with all the different version of this phone. My scenario is,

- LGH815 TWN (International) with Stock Marshmellow V20e-TWN-XX

- Locked bootloader, impossible to unlock

1. Which v29A .tot file do I use to LGUP this phone? (H815EU v29a TOT?)

2. Whats the steps to edit this .tot file to disable Big cores?

3. Do I need to update anything else in this .tot file (i.e. Do I need to update the model no? What value?)

4. My phone hasn't bootlooped but I want to prevent it from happening. Does the phone run acceptably after big cores disabled?

Thanks for any assistance.
[G4 Android Development] Tvartenis:

I never noticed any differences with or without big core,but again im not playing any games.

for changing model number it's the same procedure but i never tried it though.
[G4 Android Development] onlavu:
hi guys,

1st of all, many thanks for this TOT ROM. Its super easy to follow (thanks for the previous post, somewhere in this thread, summarising the basic steps) and fast to deploy it on G4. I was done in less than half an hour without any big effort. I upgraded from official stock non-rooted MM with locked and unlockable bootloader from Download mode and all good. The ROM is so far OK and stable on my H815, and its Nougat, finally.

cheers!
[G4 Android Development] Minto107:
I don't think it'll ever be possible. To fix it you'd need magisk, to have magisk you need to flash modded kernel, and to flash the kernel, you need to have unlocked bootloader, sorry :(

Then install version for H815 unlocked model
[G4 Android Development] dragankoz:
Excellent thanks!

But nobody has told me so far which version of the v29a .tot file I should use against my awkward phone. H815EU?

After I flash v29a will it still show the region as TWN?

I don't want to screw this up as I don't have a backup phone :(
[G4 Android Development] mamedz:
Can u guide Us step by step how to install on H818P because we dont have any methods on H818P :)

After Install Nougat do you downgrade again to MM or LP?

or stayed in Nougat?
[G4 Android Development] goran_oh:
Flash 29a for h815 via LGUP and will not be the same region will be different
[G4 Android Development] dragankoz:
From Page 1, which one of these should I download or just pick anyone?

H815EU v29a TOT

H815TR v29a TOT

[G4 Android Development] goran_oh:
Something is not right here because also you have two signal icons of 4G if you don't have any problem left like this,but if you have same problems you must do clean install again.
[G4 Android Development] :
Download Nougat 7.0 for LG G4 H818P, LG UP and drivers for your phone. Install drivers on your PC. Turn off the phone, take out the battery, return the battery, press button for UP sound, connect phone with PC and wait for download mode on phone. Go in LG UP, select Upgrade, add install package of Nougat 7.0, now select Refurbish and Start. Wait for finish.

Before, you need option for developer. Go in Settings > About phone > Usual > Information about software > 7 times click on Build and you will get notification you are developer. Now go back on Settings and go in Option developer and check USB debugging.

I've not it downgrade again to MM or LP. I do not the need for this.
[G4 Android Development] the_naxhoo:
that's because he didn't do a clean installation. It's normal in that case.
[G4 Android Development] mamedz:

[G4 Android Development] kakawak:
hi there,

i stay in the UK and recently bought a lg g4 818p for my wifes xmas :) but i want to upgrade it to nougat and was wondering what file i should download for my version of phone. the two files shown on the first page are...

H818P v29a TOT

H818P v20p 6.0 KDZ ( MM to for Back)

which one should i chose and will it cause harm if i use the wrong one?

here is some info on my phone....

android version = 6.0

android security patch= 01.10.2016

kernal version = 3.10.84

build number = mra58k

software version = v20h-ame-xx

if and when i successfully update this phone will everything be working as normal?

thanks in advance

cammy
[G4 Android Development] :
H818P v29a TOT is Nougat 7.0. I installed it and it works fine for me. There should be no problems, but problems are possible. It's all at your own risk.
[G4 Android Development] kakawak:
i understand the risks involved however, does everything work ok and is there a difference between the 2 files on the first page/pos that i mentioned? what are the differences between H818P v29a TOT & H818P v20p 6.0 KDZ ( MM to for Back)

im also assuming this will void warranty if i do upgrade, is this correct?

thanks

cammy
[G4 Android Development] :
H818P v29a TOT is Nougat 7.0, and H818P v20p 6.0 KDZ is Marshmallow 6.0. Marshmallow 6.0 is for back on MM from Nougat.

This Nougat is for phone with locked bootloader and phone without root. I do not think the warranty is lost. I'm not sure.
[G4 Android Development] kakawak:
thanks i will reply with update later :)

---------- Post added at 01:57 PM ---------- Previous post was at 01:11 PM ----------

hi,

it took about 20 mins to update mine however, when i check under model name it says h815 and not h818, does this matter? and if so, is there a way to change it?

after this update, will we receive over the air updates in the future? or do we have to manually update via the same method again?

cheers
[G4 Android Development] :
I don't know. I installed H818P v29a TOT and I don't have problems.

I think no update. It need back on stock MM for update. Before install stock MM for update need install H818P v20p 6.0 KDZ ( MM to for Back), later install stock MM.
[G4 Android Development] kakawak:
When someone finds out when LG has officially informed the consumer of the update in the UK and elsewhere. We then need to install the H818P v20p 6.0 KDZ ( MM to for Back) so we can update to the official firmware from LG.

I haven't noticed much difference but i'm sure it's faster than MM :)

Thanks for all your help!

Have you logo when bootloop? Try hard reset. And I had bootloop after installed Nougat. I did a hard reset and everything works well.

You must have done something wrong. It's up to you, not me. I only advised what I did. It working fine for me. Did you do a hard reset?

After the hardware "fix" it's working.

Please sir... i cannot downgrade it right now, already download H81820p file and try to downgrade but always fails at 21% and Error 0x2000

Thanks before sir
[G4 Android Development] :
I do not have such battery problems at Nougat. Of course, the battery is quickly consumed on this phone. After the battery is charged, I keep the charger on for about 3 hours and the battery lasts longer.

I did not try to downgrade from Nougat to MM. I don't know.

I had a problem similar to you now.

I installed Android in this order:

Lg G4 Nougat 7.0 F500K For Edit H818P

https://www.youtube.com/watch?v=M-CQmq2et-E&feature=youtu.be

H815 V20o Modded.kdz

https://mega.nz/#!H8dnXDCL!hqA-yIN3dAeuqHm-H0KltL6rfTJfb0EpVcNJYkkr0GU

Now H818P V20g-EUR-XX.

After installing these 2 Androids, if is bootloop, do not do a Hard reset, because if the system is booted, may be harmed by a modem, a network (hardware). Only when you installed stock Android, if it's a bootloop, you run a hard reset. Everything is you done at your own risk. This is my experience.

[G4 Android Development] dragankoz:
- Open up winhex

- Open the .tot file in winhex

- Search for all occurrences of 'echo 1 > /sys/devices/system/cpu/cpu4/online'

- Change each entry you find -> 'echo 1' to 'echo 0' (you only need to change a single character for each entry

- Cant remember exactly but there are several places to modify, just keep finding them until there is no more

- Now do the same for all occurrences of 'echo 1 > /sys/devices/system/cpu/cpu5/online'

- Save the file

- Flash

Starting LGUP again for flashing back to Stock H81520g_00_0720.kdz, after 21% Progress get Error Code 0x2000 Invalid command resonse again.

Changed the LGUP_8994.dll to the older 8994.dll (v0.0.3.3) for Marshmellow 6.0 , NOW after 26% get the same Error.

Are there possibilities to flash the Stock rom / Repair via Linux in Fastboot Mode? I´ve got the FWUL Linux and have access to the Phone via Fastboot ! Command Fastboot devices give me the connected resonse and some Numbers.

Have no more hope....
