Samsung Galaxy Bean recently received the Android Jelly Bean flavor via the unofficial CyanogenMod10 port. The CM10 ROM worked fine for all the users who tried it but there is a little problem and that is device’s low internal memory. Because of the low internal memory there isn’t much space left on the /system partition after installing the CM10 to install the Google Apps.
This could be a major issue for some users as most of the people likes to browse Google Maps and check their mails via Gmail App. And now this issue has been successfully fixed now, this fix basically removes the unnecessary apps from the system partition to create enough space for the users to install Google Apps. So now Galaxy Mini users have finally got the complete Jelly Bean favor on their devices, to give it a shot, you can download the unofficial CyanogenMod 10 nightly from here and latest Google Apps package from here. After downloading these transfer them to your device and then visit this thread that has all the necessary information and guide to flash the ROM and the scripts that will help you later on in order to remove the apps to create space for the Google Apps package.
