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!

★ INSTALLATION PROCEDURES ★ :
- If you want to install this ROM (coming from LG Lollipop firmware) :
  1. Backup everything you need (internal & external).
  2. Flash any LG G4 H815 Marshmallow (20x) KDZ file (check google if you need help on this step)
  3. Unlock your Bootloader
  4. Flash TWRP recovery
  5. Reboot into TWRP recovery,
  6. Make a full backup of your current system / boot & data partitions (just in case)
  7. Go to "Wipe",
  8. Go to "Advanced Wipe",
  9. Wipe "Dalvik / ART Cache + System + Cache partitions",
  10. Go to "Install",
  11. Flash the ROM,
  12. Reboot and enjoy !

- If you want to update your current SimpleGX ROM (or coming from another LG Marshmallow ROM) :
  1. Backup everything you need (internal & external).
  2. Reboot into TWRP recovery,
  3. Go to "Wipe",
  4. Go to "Advanced Wipe",
  5. Wipe "Dalvik / ART Cache + System + Cache partitions",
  6. Flash the new ROM,
  7. Reboot and enjoy !

Beware, if you flashed any init.d script before updating, you will have to reinstall them again later (only if you formated system partition).
Also, if you will have to flash modem of your choice back after flashing the whole rom (since modem is automatically flashed during flashing procedure).




★ PREREQUISITE ★ :
  • An unlocked Bootloader
  • A Marshmallow LG firmware (H815-20X - X means A/B/C/D/E/F/G/H/I/L, etc)
  • A custom recovery (TWRP recommanded), to flash the rom



★ 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).

oh , a fully stock debloated right ? very nice and handy for testing too.
with this rom we don't need to carefully test and debloat and spend a couple of hours for that.
i guess a hotplug to offline the cpus is something we won't see since it's fully stock right ? and it's 20g and not k cause of the latest (and too late and slow) v20g SEA ? maybe change title to just v20 since G will change according to the latest kdz, you won't only update to the SEA firmware ?

Yes, I was aware of this, but security patch is much more recent than a 20k (UK firmware). For me, security is more important same case with ramdisk of the kernel, it's more recent also.
Too bad that LG don't provide any "changelist" like Samsung does, it was very useful to see how much changements between each firmwares, so we can see faster which one is "better"
