IMPORTANT INFORMATIONS
- Root is now disabled by default on CyanogenMod 13. To enable it go to Settings>Developer Options>Root access and set to Apps only or Apps and ADB.
- If you get an error message when flashing GApps you're probably running out of space in your /system partition. It is recommended to have 1GB to fit the ROM and the GApps ( The stock partition table has 512mb for /system). This thread has a good guide for repartitioning and this one has a great tool for repartitioning without Odin.
- Google is your friend
- DON'T REPLY NFC IS NOT WORK. I TEST IT ABOUT 10 TIMES, AND IT WORKS.
- IF YOU NOT WORK RIL, PLEASE FLASH STOCK JELLYBEAN FIRMWARE. IT'LL BE WORK.
