BEFORE INSTALLING THIS ROM, MAKE SURE YOUR DEVICE MODEL IS THE SAME AS TITLE

IF YOU ASK ANY QUESTIONS LIKE "IS THIS FOR MODEL BLABLABLA" THEY WILL BE ALL IGNORGED

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

We'll not support users and answer questions from users which:

are running a custom kernel

have flashed mods

modified system files

didn't follow our intructions word by word

are unfriendly

And most important: DON'T READ THE OP

What's working:

RIL (Calls, SMS, Mobile data) [Dual-SIM]

Wifi (connection, tethering, etc)

Bluetooth

Camera, video codecs

Storage (both internal and external)

Storages (internal, external, adoptable storage) (*)

Offline charging

zRAM (compressed-RAM swap)

GAPPS

Tethering (USB, Wifi, Bluetooth)

GPS

Torch (flashlight)

WiFi-Direct

SELinux enforcing

New lz4 compressor/de-compressor for zram (new)

BUGS/Not working :

There're lots of bugs, but main are

No sound (beware making alarm while running this ROM), also Sound Recording doesn't work

Sound quality not too good when playing loud music or sound

FM radio app FC (due to missing libraries)

Screen recorder freeze the system (due to codecs, maybe)

Screen flickering on apps only (known as "strict mode"). Quick solution is pressing recents button, then return to the app. Currently, we can't disable it through Developer options

Distorting sound when using Bluetooth headset in call

WiFi-Direct does not work

WiFi auto-disconnect

AudioFX is not working

Battery drain caused by RIL

Cannot switch mobile data to other SIM without reboot

First time installing CyanogenMod 13 to your Galaxy V, or coming from another ROM:

Install TWRP Recovery

Reboot into Recovery using 3-button-combo (Vol-up+Home+Power)

Do a Nandroid backup! (Optional and only if you weren't running TouchWiz before)

WIPE (wipe data/factory reset + wipe cache partition + format /system partition)*

Install the ROM from sdcard using TWRP Recovery

Optionally install the Google Apps ( get it here: https://opengapps.org ) (pico GAPPS recommended) (*)

(*) NOTE: If you're about going to install GAPPS with ROM, install it right after you've installed the ROM, else you have to do a factory reset if you've booted the ROM first

If you're going to reuse our work, be kind and give proper credits

This is the only payment we're really demanding and we deserve it to be mentioned because of the countless hours we've put into this project.

Open-source doesn't mean "out of respect"
