Hi Community,
Phone is GT i9500 - I am in the UK, the phone is unlocked
can you help please. I have just downgraded from Lollipop to Kit Kat via Odin.
All appeared well except that it no longer works as an actual phone!! The Imei is now showing a NULL and Baseband appears as UNKNOWN.
Thanks In Advance

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.
Hi, I have recently rooted and bootloader unlocked a G900V and it works fine on Lollipop roms, but when the device is flashed with a MM rom via TWRP or Flashfire the Wifi wont work. IDK what is up with this. Maybe it has something to do with the baseband or whatnot, I'm out of ideas so I have to bug you guys for help, thanks in advance!
A little more Info I'm on PF4 baseband. Tried the Note5 port rom, the BS free rom and a deodexed debloated MM rom and all have no wifi. Ive tried the phoenix kernel, still no go. Tried flashing the PD1 baseband as its another MM baseband and it didnt take (via odin or TWRP ¯\_(ツ)_/¯) . So idk why flashing basebands doesn't work, maybe it'd solve my problem.
By using Getex's [GUIDE] Unlocking the Galaxys S5 Bootloader using DEV Bootloader [KK-MM]
and following the bottom subsection (If You Already Have Bootloader Unlocked And On A Samsung TW Rom) I was able to fix the problem.
Nice! Thanks GETEX!

Solution has been found.What i did was just recover the imei an serial no and then flashed the marshmallow beta version which allowed me to flash twrp and then i finally flashed the aim rom and then flashed the indian moden in 8196 and voilla volte started working.This method took me around a month
