Help! IMEI issue

Hello everyone. I think I've just messed up my device really bad. And I think there's no solution. I've search everywhere to no avail.
. I have a gt i9500, I was flashing through Odin (4.2.2 OS for my country) and my computer got stuck while installing the software. After a while Odin finished flashing the software. When my phone boot up I had no signal. It took a while until I realized my IMEI changed to Unknown. What's wrong is that I deleted the internal sd card prior flashing the software, and i did not save my efs folder. (I've done this a thousand times! )
I've tried flashing the software again, restoring cm backups but I still won't get any signal! I'm wondering if there's anything u can do to get an IMEIand gget signal, any help would be awesome. I attach what I have in my current efs folder.
Thanks... I don't fell like spending $700+ dollars for a new device

Three questions:
What version of odin areyou using?
You were flashing 4.2.2 but, what version did you have previously?
Can you see your baseband version on settings-> about the phone?

Try and flash the stock firmware and do a factory reset, hopefully this helps

thanks for the repplies, i wiped my device and i was on 4.2.1,,, however i got it working flashing the modem again, my device is working again, thanks for the asnwers

[Q] I messed up. Followed instructions but still cannot fix my phone.

Hey guys. I know for sure there is another thread about a similar problem but the biggest problem I'm having is figuring out what to do next, or better yet, what did I even mess up?
I made a thread a couple days ago here asking about the LTE option on my phone and how there was none. It's an Intl' phone and therefore I guess doesn't work on Canadian LTE networks.
Before we start, I'm using TWRP 2.7.0.0 . My phone is the UAE version of the D802, which is the D80220C. My current custom rom is Liquidsmooth MS3.2 .
So I found a list of modems and flashed the one for Bell. It was for the D803, but the thread I was looking at said it was cross-compatible so I assumed that meant it's okay for me to flash it on my phone.
Even so, I backed up my EFS partitions just to be 100% sure. I even used the .zip file that automatically backs up the current modem files. So I thought there was definitely a way out if it didn't work.
I will give you the full story of what was done and maybe I can get some guidance on maybe something I did wrong.
1) I flashed the D803 Bell modem.
2) Reboot to system, LS3.2 hangs on start up. Tried a hard restart to see if it wasn't a fluke. Nothing. Still hanging.
3) Figured the EFS files were toast, so I ran the restore .zip for my EFS. Reboot, and still hanging.
4) Said WTF? and restored my first stable rooted stock rom. It booted into the rom fine, but when it got to the lock screen I saw the "Service Disabled" and the phone quickly crashed.
5) Didn't even attempt to restart on that rom. So I tried a couple terminal commands to copy the modems1.img and modemst2.img files to corresponding partitions. Copied both just fine, but no change. Still screwing up.
So, this is where I am so far. I am in the process of downloading the D80220C UAE .kdz file so I can try to flash that one first. If that doesn't work, I'm really at a loss.
When I read into this some more, all I see is people who have totally wiped their EFS files and having to spend a whole bunch of time using a bunch of different programs to get in an recover the IMEI number.
What do you guys think?

Some good news right off the bat. I found a KK baseband for D802 and flashed it. So now I was able to restore my LS3.2 rom and boot into it fine. I see my IMEI and MAC address and can get WiFi at last!
Mods, you can delete this thread if you wish.

Samsung S4 I9505 Baseband Version Unknown and IMEI Null

My I9505 is showing unknown baseband version and null IMEI, and it is not detecting sim card.
My phone was working fine (i.e. showing IMEI and baseband version were good) on Android 4.4.2 Kitkat. I manually updated it to Lollipop 5.0.1 using firmware named I9505XXUHOB7_I9505BTUHOB4_BTU.
I did this using Odin 3.09 only checked Auto Reboot and F. Reset Time. Everything went fine and device booted with Lollipop and then this problem of unknown baseband version and null imei happened.
I searched on the internet and i think it is because of corrupt EFS. Can someone guide me thoroughly on restoring EFS.

What happens when you flash Android 4.4.2 onto the device again?
As to it being a corrupt EFS folder, unless flashing the previous ROM to your device works, you may well be screwed if you didn't make a backup. However, I don't believe it to be a corrupt folder.

Try to flash the modem twice, first time without checking auto-reboot, power off device and reboot manualy in download, and then reflash modem a second time with auto-reboot checked.

N910H stuck in bootloop

I tried flashing the stock firmware and now I keep getting the Note 4 logo going on and off every 5 seconds. Tried flashing 2 other roms and both show a failed sign on Odin when they reach hidden.img. I can still reach download mode and recovery mode though. I've also tried installing the stock firmware via Kies and its still stuck in the bootloop.

if you have flashed CM13 from RaymanFX build 8 or higher recently then you have a corrupt IMEI and that causes the BootLoop
also check if the C-roms or stock one are for SM-N910H and not C model , bcuz there are also bootloops caused by Modem , goodluck

I had build 10 from Rayman's CM 13 before this. Is there a way I can fix it? The one I downloaded was for N910H. I even tried one from Kies. Thanks for the reply

I can't seem to find it, could you please link me? Also can I apply these fixes even though my phone is stuck in a bootloop?

The bootloop is gone but I can't connect to my network. I couldn't backup the IMEI file because the phone was completely wiped.

Without the imei, you cannot use the phone for any cellular activities like sms, calls and mobile data. Also, editing imei is considered illegal so you will not find any methods to restore it here.

You just need to restore your backup and you'll be fine. Otherwise you need to flash stock with Odin

I tried flashing from a backup from last year, but all I got was a bootloop, and trying to flash stock from Odin yields this error

I have solved the issue, for some reason, flashing the special edition batman s7 edge stock rom fixed everything.
