Hi. I built CyanogenMod 11 for LG P760/P765. It is stable for use, but there are some small bugs.

What’s working: Almost all!

What’s not working/has bugs:

Tell me!

Kernel and rom features:

Compiled with SaberMod 4.8 toolchain with @JustArchi opt flags

Ramhack 819Mb

Better battery life

OC to 1350 Mhz

GPU OC to 384 Mhz

Many tweaks

Sound boost on headphones

Updated screen driver

Wifi Direct

F2FS filesystem used by default

GPS fixed (use app included in rom)

Power saving mode (automatically enabled when needed)

Black and white interface more kitkat (not blue and black like cm)

Internal sd disabled

Added BLN support (L9 BacklightMod app)

Support for 5Ghz wifi

OTA updates

Support for f2fs, ExFat and NTFS filesystem

Bluetooth Low Energy support

Less battery drain by screen (lower screen refresh rate)

Better multicore managing

What you need:

LG P760/P765

Unlocked bootloader

My TWRP (only my supports f2fs), you can download it here.

Flashing:

Flash my recovery

Boot to TWRP

Go to settings

Check “Force data and cache wipe functions to use f2fs” and “Include system partition”

Go to main menu and click wipe. Check data and cache and confirm

Flash ROM

Flash fix (if any)

Flash Gapps (if you want)

Reboot system now!

ROM WORKS ONLY WITH RECOVERY HERE!!!

DO FULL WIPE, EVEN IF YOU WERE USING CM11 BEFORE, BECAUSE NEW VERSION USES NEW FILESYSTEM. YOU NEED TO WIPE TO CHANGE FILESYSTEM TO F2FS. CHECK INSTALLATION SECTION. ROM SUPPORT LATEST BASEBANDS CORRECTLY (DEPENDS OF VARIANT).
