Here you have the steps I followed to port halium to LeEco Le Max2 and what I’ve archieved so far.

Setup sources

Follow the Porting Guide for halium-7.1 here https://docs.halium.org
my manifest: https://gist.github.com/maylton/bc1243ce24fd0ad3646f63f8b9720d41

For this I choose to use @shenoy_13 kernel for Le Max2 which he used for building SailfishOS and already has some configs for halium. Instead of adding it to my manifest I just cloned it to my local repository with the following command:

git clone - b hybris-14.1 https://github.com/VigneshShan/android_kernel_leeco_msm8996 kernel/leeco/msm8996

I had to remove hs20-osu from device/leeco/msm8996-common/msm8996.mk
and removed the line ‘include frameworks/base/packages/SettingsLib/common.mk’ from device/leeco/msm8996-common/doze/Android.mk

Kernel Image

kernel config: kernel/leeco/msm8996/arch/arm64/configs/lineage_x2_defconfig

These are the changes I have made to the kernel:

CONFIG_NET_NS=y
CONFIG_EPOLL=y
CONFIG_TIMERFD=y
CONFIG_SIGNALFD=y
CONFIG_RD_GZIP=y
CONFIG_UEVENT_HELPER_PATH=""
CONFIG_TMPFS_XATTR=y
CONFIG_NETFILTER_XT_CONNMARK=y
CONFIG_PROC_FS=y
CONFIG_INOTIFY_USER=y
CONFIG_SYSFS=y
CONFIG_SCHED_DEBUG=y
CONFIG_ANDROID_RAM_CONSOLE=y
CONFIG_ANDROID_RAM_CONSOLE_ENABLE_VERBOSE=y

Building kernel

source build/envsetup.sh
breakfast x2
mka mkbooting
mka build hybris-boot

build system image

mka build systemimage

test and debug

Follow steps here http://docs.halium.org/en/latest/porting/debug-build/

Build hybris-recovery
My phone bootlooped so I had to build hybris-reocery with mka build hybris-recovery

Install rootfs.img and system.img

Defaut halium-installer from https://github.com/Halium/halium-scripts did not work for me, só I used this one https://raw.githubusercontent.com/reivilibre/halium-scripts/master/halium-install-hostbuild by @reivilibre

I had to change default system image partition size in the installer from 160MB to 560MB since my system image has 523MB.

So I installed with ./halium-install-hostbuild halium-rootfs-20170630-151006.tar.gz system.img

I rebooted, logged in telnet 192.168.2.15
Once phone bootloops after ‘echo continue > /init-ctl/stdin’ i had to disable lxc with the following tips (must be logged in telnet):

~ # cd /target/
/target # TERM=linux HOME=/root TH=/sbin:/bin:/usr/sbin:/usr/bin:$PATH chroot . /bin/bash
root@(none):/# systemctl disable lxc@android
root@(none):/# systemctl mask lxc@android
root@(none):/# exit
~ # echo continue > /init-ctl/stdin

I rebooted to TWRP and followed the steps to create an password in:
http://docs.halium.org/en/latest/porting/debug-build/logging-in.html

Now I’m stuck at the point that i can’t connect ssh because when i configure it and try to connect i got the following message:

ssh: connect to host localhost port 22: Connection refused

Hello, dohniks,

First of all thank you for all help you have given me so far on porting halium to Le Max2.

I did just what you said, and here you have the results:

From twrp BEFORE booting once:

BUT....

My friends, I do not know what happened, but I tried to login in ssh and guess what?! it worked! If you ask me if I did anything different from other times I am totally sure I did not. I don't really know why this worked this time. The only information I can give you about this is the following:

When I failed to login ssh I was first running Linux Mint 18 and after Ubuntu 16.04. (Linux mint 18 is based on Ubuntu 16.04 {coincidence?})
My phone was running Lineage 15.1 official (android 8.1) before I format my partitions.

Now WHEN IT WORKED, I was running a stock-based rom, upon android 6.0 and ubuntu 18.04 LTS.

Do you think any of it has relation with my fails and my recent success?
