whath do you need?
B) 4.4 or 5.0 firmware with funtional recovery (TWRP).
C) conect your device to your pc and install yours drivers
1) Put "D2502_19.4.A.0.182 - PreRoot + XZDual recovery", in your internal memory.
2) Reboot in to recovery TWRP (yes only TWRP)
3) Make a BackUp (optional)
4) Wipe caches
5) Flash D2502_19.4.A.0.182 - PreRoot + XZDual recovery ( flash with TWRP)
