I am sorry you feel this way. Maybe you could try to perform a software repair which might smoothen things out.
I know how you feel and is the reason I downgraded back to KK - A good full guide is here just find and download the firmware ending with .157 and then manually flash it

Performing a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.
Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).
Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
Backup before using the methods uli posted.
