You should have better search and reading before you try to downgrade,it's not possible to downgrade from stock Lollipop to Kitkat because Lollipop has diffrent bootloader.
The forum here is full of it.

Hi mate
Seems like is possible to downgrade , your issue is with the modem

solved
open 5.0.1 stock rom
extract modem.bin
put in odin (in CP part not ap)
flash...

Wifi it does not work on Galaxy S4

Hello, I tell them my story.
I have a i337m S4 ( has the same specifications an i9505 ) .
The fact is that if I flash one custom ROM or Lolipop original firmware , the WIFI does not work me , but if I install a AOSP ROM -CM 5.0 or 6.0 wifi works me perfectly.
Like, if I install the firmware KK me the wifi works perfect.
Equal treatment to flash the modem , but I find for my baseband as it is: I337MVLUGOC4
For example , finished installing the Albe95 ROM or Imperium ROM , the wifi is activated and the Second turns off and goes well ...
The point is that if I stick a Custom ROM Lolipop or Firmware Lolipop from TouchWiz , the WIFI does not work me :crying:
sorry for the English , I use translator

Which country is your phone made for? I see that OC4 may not be the latest ROM for the phone: http://www.sammobile.com/firmwares/database/SGH-I337M/
