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?

Wifi (connection, tethering, etc)

Bluetooth

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

Camera

Video codecs

Storage (both internal and external)

MTP storage (both internal and external)

zRAM (compressed-RAM swap)

GAPPS

USB OTG

Tethering (USB, Wifi, Bluetooth)

Sound recording

Torch (flashlight)

BUGS/Not working:

Weird sound when using loud speaker while calling

GPS doesn't work

Recorded videos through camera produces wrong color

Offline charging doesn't work

Switching to other fonts will get bootloops after restart. In this case, if you use TWRP recovery, go to File Manager >> delete "themes" from /data/system would help you escape this without factory reset

First time installing CyanogenMod 12.1 to your Galaxy Grand Prime, 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)
