You have an N900 though, so you'd need an N900 modem, preferebly the latest one for your model.
There are a few listed here: http://forum.xda-developers.com/showthread.php?t=2475714 but you need to find out which one to get (XXU, UBU, DXU etc)

well i manage to bring back sound and baseband by flashing australian firmware and doing some modem flash over it
after that i tried couple of old roms but still imei remains "/01"
now i flashed back the australian firmware, this time didnt have to flash modem to brig back sound as it booted up normally
but still im struggling to fix my imei number as now i have a wifi phablet instead of working phone??
is it possible to fix the imei number somehow...this whole thing is driving me crazy!!!

Follow this link http://forum.xda-developers.com/showthread.php?t=2567133
Same thing happen to me. U cant bring back ur Ime flashing some roms or firmware. Because Now your EFS is blocked by KNOX. After you upgrade Do not downgrade or flash older modems .
This is the method you can bring back your phone. Before try this method flash the lates firmware then try these commands.
Good luck

Galaxy S4 GT-I9505 IMEI / Baseband NULL / NULL
Hello every body, and thank you at advance for multiple sharing , and help solving android problems.
Am facing the same problem of NULL imei and base band as well, i endured this issu after a month of experiencing a new official update from kitkat 4.4.4 to lollipop 5.0.1 it worked fine at first but with use i had heat issu, and loss of network 2G intermittently ..
i tried to root the device, but it gave no solution, the re-install of lollipop non-official leads me to the loss of IMEI numbre.
i triyed to downgrade to kitkat, i didnot found the 4.4.4 version in samsung stock, i've downloaded 4.4.2 , reinstall, the lollipop is still persisting.
back to hard samsung wipe data , also gave nothing.
please advise.
thank you
PS : i have no ESF backup

lollipop 5.01 and the custom rom was based on kit kat 4.2 (aroma ozcan rom 6.3) everthing went fine till the final boot and there was no
imei and i was not able to make any calls , i searched every where i could , i tried to restore my nanadroid backup , efs partition everthing went wrong . I tried one or two method from some website but that too was not hope full finally with GODS GRACE I stumbled upon this thread and id worked
i followed a youtube tutorial for the basic of modem flashing just follow his video for the odin version and he advise to flash the modem twice i did exactly that and it went fine and now i am albe to recive and make calls
this is what i did
downloaded the odin version 3.04
downloaded the modem file that op provided
unzip it to desk top
run odin as administrator
un checked "reboot"
turn the phone into download mode and connected to the pc
selected "phone" in Odinn and navigated to the bin file
hit start

You need to descripe what you did. There are many ways that can result in imei null.

If it was working before you dropped it, then you have hardware damage and the above method will not fix it. Bring it to a service center.

No signal i9500 after downgrading to 4.4.2 [i dont know which modem should i flash]

Soory if it sounds dumbish, im from romania, carrier - orange. I flashed some stock firmware MBC-Germany or so, if it counts, that's the one i used to flash all the time since romania was not withing those firmwares. I know the device is old, i'm planning to buy a Letv 1s or redmi note 3 but i have to do something with this overheating thing, i can't sell it like that. I heard it wouldn't overheat on 4.4.2, if you have advice regarding this problem, please

Flashed several modems, got signal now but can't use mobila data -> "No signal found for mobile network". I tried modems starting with these letters: "XX,DK,DD". I'm now using DD one since i got best signal but no network signal at all, any solution for me ? IF IT COUNTS, i've been using cm13 android 6.0 before flashing stock 4.4.2 and i have an efs backup done @ TWRP recovery, tried restoring it, didn't solve anything.
EDIT : Still cannot be called -> "Not registered on network" - i'll try further modems hoping it will eventually solve my problem.
UPDATE: Tried them all @ Modem thread. I'm expecting help, can't solve this on my own, i'm a noob.

You sure you have an I9500? If so, it was imported. Enter download mode please and read off the information on the screen.

There is no firmware for Romania as the I9500 isn't available in Romania. Thus any I9500 firmware from sammobile.com should work. Flash the full firmware via Odin and not just the modem.

I mentioned that all the problems started when i flashed GERMANY STOCK ROM 4.4.2.

I'm going to ask an odd question here, but do you still have the original box? If you do, the full model number of the phone will be on it, e.g. I9505ZKAO2U. If you have that full model number, post it here.
In the meantime, try installing one of these.

Didn't buy it new, i don't have the box of it anyway. How would that help ? It's not a fake s4 for sure if you have any doubt.

The full model number on the box as described would have allowed me to pinpoint the original firmware that was supposed to be on the phone. The last three letters are the CSC of the phone, and thus the firmware that the phone should be using.
Now, the only way to find out that information is by parsing it via the IMEI, which has the country of origin within it. To the best of my knowledge, none of the sites that allow you to enter IMEI numbers will retrieve that information. IMEIData.net used to do it, but require a subscription now.

Imei is unknown, got efs backup from back when i was on 6.0 gearcm. But i can't read it in any way. Tried restoring it, the imei is still unknown.

Take it in for service, especially if the EFS backup doesn't restore the IMEI to the device using the EFS Backup tool.

I really doubt that's so much of a problem. I remember encountering a similar problem 1 year ago when i flashed 4.4.2 rom over 5.0. I can't remember what i've done but i know i had been struggling for 3 or 4 days. I remember, anyway, it was related to some applications from play store, one called busy box or so. Moreover, then i had no EFS BACKUP. That's why im so careful now with it. My guess is that if i flash back to 5.0 that problem will be gone, but the phone is overheating, unusable if you ask me. Hope someone will be able to help me
Found that on youtube - https://www.youtube.com/watch?v=XT42ri37RBU.
Now my question is how do i find my imei within that backup cause the files are .md5/.info/.win/.win.md5.
UPDATE : Flashed that rom, same problem.

Bump. Flashed gearcm 6.0 and a XX modem and its working well now. Any help there, still? I have to flash 4.4 again soon and I need a solution.

Actually, the point is simple:
Anytime you get unknown baseband after downgrading, flash Lollipop modem back, done.

Download the stock firmware for the phone from sammobile.com, unzip it, and flash it using Odin.
You flash a stock rom the same way you flash twrp with Odin.

The kernel is inside the rom from sammobile.com.
