[Q] topic

i recently flashed the leaked 5.0.1 Android L firmware to my Galaxy S4 i9500. After using it for a while i wanted to downgrade to KitKat 4.4.2 but every time i try to flash the KK firmware, it fails and brick my phone and i have to re flash Android L to recover my device. Ive used the all options in ODIN (AP. BL. PIT, CSC) etc etc.
