Downgrade Sprint S4 from Kit kat to Jelly Bean

[Nick B5]

I sent my phone in for repair on the micro usb port to Samsung.(Because it was under warranty) It was sent in with 4.2.2 and they updated it to kit kat without asking me. After a month of hell dealing with all the freezing a crap I want to roll back to jelly bean. Could someone please help me find some info as I cant find too much and I am a newbie on this site. Thanks in advance

Welcome to the forums.
The last I knew, if you attempted to roll back to a version of Samsung/Android prior to 4.3, you can cause the device to be bricked.

Golfdriver97 is correct. After 4.3, Samsung added Knox on all of their devices, which makes a firmware downgrade impossible.

Sent from my Galaxy S4 running SlimKat 4.4.4
