You need to flash a Lollipop modem. Or you could reflash the Lollipop firmware.
I wouldn't flash the link above you. He has no description at all of the file.

Just as OP, I downgraded to kitkat, in my case because of the terrible battery life S4 gets in lollipop. I have spend days trying to fix this, I have tried all kinds of wipes and ROMs, until I got a decent lollipop ROM and flashed just the modem image, and the problem was fixed!
I thought I had wiped my IMEI, because of the IMEI null and Baseband UNKNOWN issue, but as soon as I flashed the corresponding modem, I "got it back". I do recomend you however, to backup your EFS partition, because apparently you *can* wipe your IMEI when you flash ROMs.

Am having this issue from quite a day.I installed lollipop offical firmware provided by blackcat..
i wanted to revert back to kitkat so i flashed stock firmware from sammobile everything is working great except for imei baseband issue please help me.I already tried flashing modems.
Are u have a Backup from your imei and efs?
No brother i do'nt have anything
No solutions yet for those who wish to revert to kitkat.
But a workaround is to use the Lollipop official leaked modem with any kitkat rom.

You're not the first with this problem. But I haven't seen any solutions yet.

Go To Your Phone Nd Take The Screenshots nd then post over here. If you've corrupted your IMEI then you're in a deep problem! Give me the link of 5.0.2 Russian Stock rom which you flashed.
Hello guys. A year ago, I flashed stock Lollipop after stayed some minutes in CM13 rom and lost my IMEI and Baseband. So, I want to know if a fix is already available or somebody that faced this bug figured out how to fix
Note: in Kitkat is normal.
Thanks in advance
