[REQUEST] LG h840 custom rom - LG G5 Questions & Answers

Can anyone make a custom rom for that phone? Like lineage os?!

---

Yes please, I dont understand how is that there are many roms for h850, for example, and there is absoloutely nothing for h840

---

I'm waiting for a custom ROM too... Nothing for H840 even if it is similar to G5 and has bootloader unlocked. Why this?

---

I asked the dev of Fulmics Rom if it would not be possible to build a rom for the H840 since I have used his rom's before and they were brilliant. Got some snotty reply from a newish user which kinda put me off. This is not the XDA I used to love and support. It's a pity I don't have the time to dabble in personal projects else I would put something together to do this.

---

How can we contact a developer or who do we have to talk to?

The problem is the G5 has many variants with different chipsets or additional HW/firmware features. You cannot create a generic ROM across all of them so they choose the ones they want to support. Also you need an unlocked bootloader to apply a custom ROM and only 3 of the variants have been unlocked.

The H840 bootloader unlock is supported. The guide here explains all steps required to unlock, root and install TWRP. Check, Check and Check. The Fulmics dev has been doing this for quite some time and definitely knows how to put together a rom which will flash different kernels for different devices.
I have been around XDA for ages, built some roms back in the day so I understand exactly what is required. It is just the attitude of users that has changed over time that puts me off from pursuing a way to get a rom on this device. I don't feel like being harassed by people who do not take the time to notice the "Senior Member" badge, which basically means I am not a noob.

Dear Senior Badge Owner, I'm sorry I was trying to be helpful.
It's people like you that put me of XDA. So you don;t like people harassing your expertise, go make your own ROM
*Plus* senior just means you've been a member a while, not that you're an expert or important. So assuming the senior = knowledgable is not the case.

Oddly enough, I was explaining to you why I asked once and abandoned the effort in the Fulmics thread. Then for some reason you react exactly the opposite of what I expected.
So I am not going to edit the post to make it appear that I am being silly while attempting to be self important but if you click on a member's user name, you can basically see their history. I never said I am important, I am however a professional developer but unfortunately do not have the private capacity to build roms or develop on pet projects like I was able years ago. But back to the history, instead of an instant flame it takes less than 2 minutes to see that a user is/has been an active contributing member of the forum and as such display a level of civility.

The day when junior members stop with these inane replies aimed at senior members who have been a part of xda for close to 10 years is when I will start contributing again.

Yeah click on the name and see you rattle that "Senior" thing before, you like to point your seniority out. And the recent posts asking devs when you going to support H840 for ROMS and Mods, just like a noob. A rule most seniors, or people been around here 10 years, know is to be civil and not harass devs to support your device.

So you know what needs to be done but you're too busy. Yet you expect the fulmics dev to take time out to support your device.
But yes civility should be maintained so I apologise again for insulting your knowledge without doing a background check on your profile.

I distinctly remember simply asking if he plans to develop for the H840, since I have used his roms on my previous LG G5 and they where brilliant (which I pointed out as well) and receiving a snarky comment from a user who couldn't bother to see if I knew anything about anything and pointed out exactly what I pointed out to you. When I 1st joined xda everyone kinda just worked together and as a rule you asked senior members for help (which I have provided numerous times just ask a member @CRACING for example) and didn't go off on a "NO ETA!!!", "DONT BE A N00B!!" or other tangent. I actually posted about this before, attempting to remind everyone that they too were once a noob.
I guess making like minded acquaintances on here is not like it used to be.

Right now I am uploading the source that I was working for some time. If any of you with a decent PC (8gb of ram) have the time and some basic knowledge maybe want to give it a try. I never finished compelling a build with this sources so I don't have any idea how it was going to end if you will going to try and you will have some trouble compelling this I'm afraid I will not going to be able to help you that much keep in mind that I'm not Developer and I have 0 time and a old PC with only 4Gb of ram
source link:
https://drive.google.com/open?id=0B67rXGNB6IzwaU43MWVuTHpKNzA
I suggest to use a LTS version of ubuntu, in this guide I'll be using Ubuntu 16.04
Let's start with a bit of cleaning:
Code:
sudo apt-get remove openjdk-* icedtea-* icedtea6-*
Install java8:
Code:
sudo add-apt-repository ppapenjdk-r/ppa
sudo apt-get update && sudo apt-get install openjdk-8-jdk
Install build tools:
Code:
sudo apt-get install git ccache automake lzop bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 g++-multilib python-networkx libxml2-utils bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev squashfs-tools pngcrush schedtool dpkg-dev liblz4-tool make optipng maven
Install repo:
Code:
mkdir ~/bin && curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo && chmod a+x ~/bin/repo
Edit ~/.bashrc (in this exaple I'm using gedit to do it):
Code:
gedit ~/.bashrc
Add those 2 lines at the bottom of the file (we are going to add also ccache to speed up our build time):
Code:
export PATH=~/bin:$PATH
export USE_CCACHE=1
Save it, close gedit and run:
Code:
source ~/.bashrc
Let's create some folders where we'll be doing the magic:
Code:
mkdir ~/android && cd ~/android
mkdir lineageos && cd lineageos
Initialize the local repo and download the source:
Code:
repo init -u git://github.com/LineageOS/android.git -b cm-14.1
repo sync --force-sync
It'll take quite some time, depends on your internet connection.
Once it's done downloading and checking out the files:
source build/envsetup.sh

I dont even have linux lol

This is the easiest part even my dog can install Ubuntu

I am very curious to see if it would be possible to build this on Windows Subsystem for Linux. It is basically Ubuntu server core running inside of Windows 10. Full apt-get support which means all the tools can be installed without having to designate a seperate machine to it.
