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 Guys,
My Phone Samsung Galaxy S4 Black edition(India INS) got automatically upgraded to 5.0.1 Lollipop from Kitkat 4.4.2.
Since the upgrade i feel there a performance issues in my phone.
Now,I have decided to Downgrade it to Kitkat.I have identified the correct firmware from SAM Mobile below,
Model GT-I9500
Model name GALAXY S4
Country India (Black Edition)
Version Android 4.4.2
Changelist 923538
Build date Wed, 05 Mar 2014 07:25:51 +0000
Product code INS
PDA I9500XXUFNC1
CSC I9500YDDFNC2
I know all the procedures to Flash the firmware using Odin.
I have few questions below,
1)If i downgrade to the above kitkat version,Will i face Null IMEI problem and why?
2)I have also heard,the workaround for the null imei issue is to flash the modem.bin from lollipop firmware,then Baseband version will be still from Lollipop.Will this create signal problems in future?
Please share yours views and suggestions on this.
Thanks

There is a tool created by AntaresOne to backup IMEI. Do a backup then flash the kk.
Performance issue is usually because you didn.t factory reset phone after a major update.

Thanks for the reply.
Do i need to root the device to take the backup of IMEI using AntaresOne?
once i have downgraded to kitkat,I have install AntaresOne and restore the imei backup which i have taken earlier right?

Thanks.I'm not interested in rooting my device.
After downgrading to kitkat, if i get Null Imei issue,i can still resolve the issue to upgrading to the latest lollipop firmware right?

Theoretically, yes. But you know that sometimes bad things can happen.

You will get imei null for sure. That's normal. You have to reflash a lollipop modem afterwards.
I downgraded my s4 from lollipop to kitkat with odin and firmware from sammobile and i didn't had problem with imei.

Can you share the firmware details which you downloaded and flashed from SAM Mobile?
Is the version of S4 which you are using is a Black edition?
