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 lost the IMEI maybe. Did you make a backup of your EFS/IMEI before install Lollipop? You will have to reflash Lollipop again if not.

Downgrading to kit kat may not have downgraded the bootloader which means the phone is running a kit kat ROM and baseband on a lollipop bootloader.
I'm unable to downgrade from 5.0 stock firmware to kitkat due to battery drain extremly fast and unable to root in 5.0 stock fw , currently I have tried to flash 4.4.2 (N900VVRUCNC4) via odin but failed and I think because 5.0 block bootloader of older version. Everybody please help me with 2 issues:
Downgrade from 5.0 (N900VVRUE0B6) to 4.4.4 (N900VVZWDNJ6) or 4.4.2 (N900VVRUCNC4) kitkat ?
Issue with battery in 5.0 stock, is there any fix or patch to extend battery life ?
Thank you so much.
Can't downgrade to 4.4.2 but can downgrade to 4.4.4. I would install 5.0 like I did and the factory reset the device. It worked wonders on mine.
If 5.0 is better for other people then you have some extenuating circumstance. If hard reset does not work then you have a hardware issue and should have it exchanged...
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.
Is it possible to downgrade the N910F from Lollipop (POF2) to KitKat (ANK5)?
YES, IT IS POSSIBLE.
Before yesterday I've never used KitKat on my Note4.. When I bought the phone I had no time to try it (KitKat) because I've straight rooted it and flashed a Lollipop based ROM.
Then yesterday I wanted to try a KitKat based ROM and I've lost about 30/40min looking in the forum for the answer to the question Is it possible to downgrade the N910F from Lollipop (POF2 or whatever) to KitKat (ANK5)?
I could not find a proper answer.. there was this BOF5 bootloader can not be downgraded but it was always in a "strange contest" and it did not convinced me.. after 30/40min I said ***k *t and I just performed a full wipe from TWRP, flashed ANK5 modem and bootloader via ODIN, and installed the KitKat ROM from TWRP.
Sorry for the Question/Answer but this thread may will help someone to save time.
P.S.: My KitKat adventure lasted only 10min... It looked ugly to my eyes! Went back on POF2 and now trying out AICP

When you flashed that lollipop-based rom, that was a custom rom I assume? Did it contain a bootloader? Maybe you were still on the KitKat bootloader.

Yes, it was a custom ROM. No, it didn't contain bootloader. No, I wasn't on the KitKat bootloader, for sure my bootloader was POF2. Trust me if I tell you that before the KitKat ROM I've flashed too many Lollipop ROMs with many Lollipop bootloaders.
