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.

Can't flash A500F roms on my A500F! Baseband issues

Plz help
I tried to flash cyanogenmod for my A500F(Lollipop 5.0.2) through TWRP.
When I flashed the rom, the message on the screen said"this rom is for a5ltexx. This device is a5ultexx"
However in about phone, my phone model was A500F. Ignoring this, I flashed the a500fu rom.
Rom flashed successfully. BUt my Wi-Fi and sim card were not working due to baseband issue
How to flash cyanogenmod and have the same baseband?

I presume it's an unlocked phone (works on any network)
You can try manually add apn settings
Flash a different firmware via odin
In regards to twrp and custom rom make sure are flashing correct versions
TWRP latest version is twrp-3.2.3-0-klte.img.tar
https://dl.twrp.me/klte/
Flash twrp.tar in odin in AP section
LineageOS
https://download.lineageos.org/kltedv
In twrp format system data cache
Flash rom zip
Flash gapps (mind the gapps)
Flash root zip (magisk optional)
Restart

[Hard Problem] Unable to boot up after flashing

Hey guys, I got an Samsung Galaxy Note3 That really stuck on logo before flashing the device. The model number is SM-N9005. I tried to flash the device with the never version of Android and it doesn't work. I tried to flash with the older version and custom rom but it still did the same. I can't figure it out what's the problem. I hope you guys help me out with this issues. I use odin v3.0.7 and if you guys had any suggestion using the other device please let me know about it. Thanks

Just download the stock firmware for your device
Just download the stock firmware for your device from sammobile.com it's free and flash it with Odin
This will put you on 5.0 lollipop but then you can just flash twrp and install any other custom ROM and btw I think that the problem you are facing is because you didn't flash the new bootloader and modem for the ROM you tried installing.
