Want to free some RAM?
You're in the right place.
First:
We will start by removing unnecessary system apps that consume RAM like:
-APR.apk
-BatteryProtect.apk
-wifiPowerSavingMode.apk
-gps_log_tools.apk
-Remove unnecessary keyboards if you only use hardware keyboard. (touch keyboards eat ram)
-Remove motoswitch.apk and install Holo Launcher as system app
-Download Holo launcher latest full version from HERE
-Install to system using adb or root explorer
-Disable "wireless networks" from location and security if you don't use it alot
Second:
Disable autostarting apps using "Auto starts" application, download from HERE
-Disable apps that start by them-selves automatically when system starts like maps, google play, etc..
-This will save you much RAM, and the disabled apps will start only when you want to start them.
