You cant downgrade the stock firmware. why do you want 4.2.2?
Sent from my SGH-M919 using XDA Premium 4 mobile app
I would like to downgrade to 4.4.2 because the 4.4.4 version is hard to root (i've rooted with Odin) but it lost the effect in lock screen (light that follow the finger without touch the screen).
Use cf-autoroot for root, and for the light you need to have air gesture or air view enabled
These settings are enabled, I compared all settings with another S4 and they are the same but it doesn't work at 4.4.4. Any suggestions?
