Install CyanogenMod 13 ROM on Galaxy S3 (Android 6.0.1 Marshmallow)

The legendary Samsung Galaxy S3 has now received the second custom ROM based on Android 6.0 Marshmallow. The first ever Marshmallow ROM for Galaxy S3 GT-I9300 was AOSP, based on Android Open Source Project. It was very buggy and very unstable.

Now, the second ROM is CyanogenMod 13, which has a lot more features and it is more stable. CyanogenMod 13 is based on the latest CM sources and features Android 6.0.1 Marshmallow on board, which is an update over the old Android 6.0 version.

According to ‘forkbomb444’, the developer of the ROM, many things are working. You will be happy to hear that important features and services are already working such as WiFi, Bluetooth, NFC, colors, SD Card, RIL (phone calls, SMS, mobile data), camera, DRM and GPS. Some known issues include non-FAT32 SD cards not working alongside WiFi P2P.
