The Samsung Galaxy Mini has recently received Android 4.1.1 Jelly Bean in form of an unofficial port of CyanogenMod 10 by XDA Senior Member TheWhisp. While the ROM seems to be working fine for those who have given it a shot, there is a problem. Due to the device having limited internal memory, there isn’t enough storage space left on the /system partition after installing CM10 to be able to install Google Apps. This can be a major issue for many, as most of us rely on Google Apps. Luckily, there is a fix for this now, thanks to XDA Senior Member killar_aka_arabu, who has written a script that removes unnecessary apps from the system partition to free up enough space for Google Apps installation.
To get started, grab the latest unofficial CyanogenMod 10 nightly and the latest Google Apps, and transfer them to your phone. Next, visit the guide thread and follow the instructions provided to flash the ROM and free up internal memory space by running the provided scripts, before flashing the Google Apps package._________
