[ROM][ALPHA][UNOFFICIAL] CM 12.0 for Galaxy Grand Duos (I9082/I9082L) (20141128) 2SIM

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0 (Lollipop), which is designed to increase performance and reliability over stock Android for your device

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.

All the source code for CyanogenMod is available in the CyanogenMod Github repo.

Device-specific source code for the Samsung Galaxy Grand Duos are available fromhttps://github.com/pawitp/android_device_samsung_i9082 and https://github.com/pawitp/android_kernel_samsung_i9082.

Known Issues

• screenrecord does not work
• FM Radio does not work
• Sometimes wake up causes music stutter
• Wi-Fi HAL (i.e. Scanning MAC Address Randomization) not implemented
• Sim Tool Kit (STK) not fully working
• Video in YouTube app sometimes freeze
• Camera app sometimes crash on close
• Unable to un-pin screen without rebooting
• root not working properly (su was shipped with incorrect permission, you can make it work by chmod 755 /system/xbin/su)
• Swipe-typing and face unlock are NOT ROM issues. They need the proper libraries from Google Apps.
• Does not work on 4.1 stock ROM's bootloader, please upgrade to 4.2 before flashing

Additionally, Dual SIM has the following limitations:

• Both SIMs are always enabled (no way to disable one SIM)
• "Receive incoming call while data is enabled" is always enabled
• Cannot toggle SIM2 data from quick settings

Installation

1. Make a backup!
2. If you were on CM 10.1 or a stock ROM prior to 4.2, upgrade to 4.2.
3. Install ClockworkMod recovery with SELinux support (.tar) (.zip). Older CWM will result in a "status 7" error.
4. Reboot into recovery
5. Wipe data if coming from stock or another non-CM ROM (You may get a "staus 7" error if you fail to wipe.)
6. Install the ROM
7. Optionally install the Google Apps Addon

o upgrade to a newer build, simply flash the zip. There's no need for data wipe or flashing Google Apps again.

20141116: Initial release

Thanks
- The CyanogenMod team for providing a great ROM. Without all the compatibility work which went into it, this ROM would've been much harder to make
- My real-life friend for letting me borrow his phone to work on this
