WARNING

:

This rom concerns LG G4 (

H815

/International) version only

You will void your warranty after flashing this rom

I'am not responsible of any damage caused to your device after flashing this rom

Some reading..

Keep it Simple… keep it SimpleGX !

SimpleGX is only looking for simplicity and stability, trying to aim for best battery life, smoothness and performance experience, than a pure stock rom.

It has been mostly designed for people who like to "flash-and-play" (you flash and you can directly enjoy, without doing much customizing to enjoy best battery life and smoothness experience), that is how I always liked things.

Choice is large in H815 roms, but I wans't personally enough satisfied after testing all of them, so I decided to make mine for my personal use first, and share it to the community.

Please keep in mind that I did this rom for my usage first. Don't complain if it does not have any app you need.

Also, keep in mind I still dont qualify myself as of a real developer, but just a basic person with some android/linux knowledge already.

As always, I’m enjoying sharing my contribution here on XDA for free, which taking me a lot of (my free) time to test before releasing (my device has already been a lot tortured to release this rom) so, if you can offer me a little beer, it will be really appreciated!

★ FAQ ★ :​

Can I flash this ROM into H811 ?

No. Yet I don't want to maintain 2 versions as I don't have H811 device. Also, I'm not a fan of blind releases on a device I don't own, althought I did it for my kernel which always have H811 compatibility. You will have to flash any other H811 roms/firmwares and then flash my H811 kernel version.

Please add this LG app !

If your app is not there after flashing, it's probably because I intentionally removed it. Don't forget that this ROM has been designed first for my own usage. Please check THIS post on how to add it (

experimental and for advised users only

).

Need more battery ?

If you don't mind sacrifying a bit performances, then you can try to turn off ZRAM (you will find the script into my kernel thread in Add-ons section). You will benefit a bit better battery life (from my months experience).
