Downgrade Note 3 SM-N9005 from Android 5.0 to 4.4.4

After Android 5.0 upgrade my Note 3 has many bluetooth problems that stops me from using my smartwatches (Moto 360 and Pebble Time). Frequent dropped connection on bluetooth, both moto 360 and pebble can`t connect, i have problems with my car stereo, and sometimes when i push the back or home button on an app, nothing happens. Tried everything, wipe cache, phone reset, deleted cache from the Bluetooth and Bluetooth test app, factory reset the pebble and moto 360, no luck. :(
Android 5.0 is a big mess and i can`t use my bluetooth devices, that worked perfect on Android 4.4.4.
My phone is still in warranty, i have never done root on it, only installed stock updates, OTA, from Samsung.
I want now to downgrade back to Android 4.4.4 stock with ODIN. I want to download stock Android 4.4.4 for my Samsung Note 3 and flash it with ODIN. Can i do that?
Please help, Android 5.0 messed up my phone.
