These are the only downgradable models.

Who was this someone? If someone says: jump in front of that train! Would you do it? Next time please do your research, before you try to turn your expensive device into a paper weight.

Well I know this wasn't quite helpful, but I guess you learned your lesson. So which version of the phone do you have? Why dont you just download the latest ROM for your device and flash it? Then you at least should get back a working phone. Then do a little research and try to figure out, if a downgrade for your specific model is possible.

Did you already try to flashnthe stock ROM? If not, I'd recommend doing it. Then search for how to restore efs backup. Then I guess maybe after a factory reset you should be good to go.
Edit:
Here are 2 links. So as far as I understand it, you either need the app, or adb to restore your efs partition.

Flash this UK BTU firmware. It seems to be the best one and will flash fine almost 100% of the time.
http://www.sammobile.com/firmwares/download/99544/G925FXXS4DPIJ_G925FBTU4DPH1_BTU/
Once done root your phone with cf autoroot. It is compatible with your device and the above ROM.
After that install this partitions app
https://play.google.com/store/apps/details?id=ma.wanam.partitions
Top right corner click settings and restore partition. Insert your backup of efs and restore.this will most likely fix your problem. If you dont have a back up of efs theres not much else you can do.
Keep me updated.
Edit: what did you do exactly to lose imei? Flash an incompatible rom? Or what?

Flash stock firmware
Flash twrp
Do adb shell from twrp
Wipe efs using the following command
mke2fs dev/block/sda3
mkdir /efs
mount -t ext4 /dev/block/sda3 /efs
Factory reset and reboot
Still no imei?. Try flashing stock again
I don't know if it's gonna work with s6 edge but it worked in some cases for note 3. On you own risk. You have nothing to loose anyway since it's already useless.

Male sure your efs backup is saved internally on your phone. On the app top right corner click settings and restore. Locate the efs folder you backed up and click start. Once done reboot to recovery. Wipe data and cache and reboot.

Nope, I wasn't sure what to do, didn't want to make it worst so i came here for help.
Should I do that?

With the state of your phone now, if you were to reflash a rom between the two, you would have to flash the odex version because it will have everything stock, while the other deodexed one might have one or two things taken out, I believe.

Could be a bug somewhere, development in this device is still very small and new.
@OP, reflash stock as suggested, might be lucky and get your details back.
i just flashed a stock rom, no luck.
still no imei. is there anything else I could do?
Not sure if this is possible but use someones efs img and inject your own imei inside it. i wonder if this would work

I tried doing that on my old device with no luck, but it may work for him.
I had the exact same issue, unfortunately I had no success, I ended up sending my phone back to Telstra and getting a replacement
I have the i9305T from Telstra and I made the mistake of trying to install CF-Root 6.4 for the standard i9300. Once I did that I soft bricked the phone. I have been able to download the Telstra ROM from SamFirmware and install it and be able to get the ROM up and running again. I have lost the ability to connect to the mobile network. I can still use the phone to full capacity and even connect to wifi. I haven't be able to work out a way to repair the mobile network connection.
Can you suggest any ideas?

cool, i'm just waiting to get hold of original Everything Everywhere UK ROM before I do that.
OK, i've triangleaway'd my flash counter.
so now my phone in download mode reads:
Odin mode
Product Name: GT-I9305
Custom Binary Download: No
Current Binary: Samsung Official
System Status: Custom
Now, it says samsung official as i used a foreign (to me) firmware from sammobile, i still want to change this to the everything everywhere ROM.
Why does system status still say custom? is it because i still have root? how do i remove it after i install the EE ROM?
The EE rom shouldn't add to the flash counter so i'll be OK to remove root then install it.

[Q] GT-I9300 not registered on network

Hey, guys!
This is my first post in this forum.
My situation is the following: a friend of mine came to me because her SIII GT-I9300 was stuck in the SAMSUNG screen. After a little research on the internet, I did a wipe data, which did not work. Then I researched a bit more and flashed Android 4.3 using Odin. Android was running OK, but I got "not registered on network".
My question is: in order to fix this problem, should I worry about the IMEI? (when I did the wipe data i didn't do any backup...:silly.
Any help is welcome. Please have in my mind that I'm a noob...

Yes root it then install cwm recovery then download zip file and put it onto your internal sdcard
Then reboot in CWM and use "install from zip".
Well, guys...
I did what you said... didn't succeed. I installed those patches, but it still says "not registered on network".
I wonder if it is an IMEI / EFS folder issue... As I mentioned on the initial post, I don't have a backup EFS folder.
Should I try to flash the stock ROM (I mean, the factory native ROM) so as to try to recover the IMEI?
If so, I don't know what was the original firmware because I got this mobile from a friend.
Any ideas on how to figure it out?
Thanks in advance.

I've had a quick look on the net, but I couldn't find any 'step-by-step'...
I mean, do I have to save those 2 files (modem MG4 + kernel) in the SD card and flash using CWM?
Where can I download it?

these are released after 4.3 upgrade with the issue not registered in network
Flash
I would go back to an older version of standard rom. See if that restores imei efs back to version 1. Sammy mobile unbranded uk is version 2 so use an older version than that. I have gone back to this from version 4.3 stock. If phone boot loops after flashing do full factory reset. Then check imei. If still not ok. Install kies and it will upgrade to 4.3 and imei will be back.

Koj,
Could you please post the link for the older version of standard rom? After flashing it, how can I check the IMEI EFS version? I just want to be sure I'm strictly following your tips.
Just to remind you, I got this S3 from a friend who had bought it in USA, and now I'm trying to use it in Brazil.
Thanks in advance. Greetings from Brazil!!
http://www.sammobile.com/firmwares/1/?model=GT-I9300&pcode=ZTO These are a list of Brazilian roms choose the september 4.12 version. You will need to register before you can download. To check imei go to about device then status or from phone keypad enter *#06#

Lg l80(d380): No imei, service disabled.

This will not help if he has no IMEI.
You most likely corrupted the efs partition. In such a case without a backup you can try flashing a stock rom or modem, or you will have to send it in.

Not even close. All a factory reset does is remove and reset system and user data. Flashing a stock rom will format all partitions and reload all the stock apks, which factory reset doesn't touch

No idea I would contact the seller that sold the device to you. I would contact LG about it. They may advise you to send it into repair. There are ways to fix the imei but messing with the imei is illegal so you wont find help here on how to do it. Google is your best bet if you are left with no option. I nor XDA advise this though.
Hi,can i ask some question about my phone LG D380 my phone has no signal and IMEI,i use it yesterday but a few hour it has no signal and i dont use messaging and call...pls give me some advice how to fix it....tnx

Same here (Think we done the same thing with the Marshmallow 6.0.1 leak) I backed up, but the new version of TWRP I have has EFS as a separate option, I never even noticed and never backed it up.
However I Flash with smartswitch, and after reflashing the bootloader with odin and a Root Kernel, I can boot into the device and using root explorer, I CAN see my EFS folder. I deleted the .nv_data.bin files and changed the .nv_data.bak to .nv_data.bin (was an older date) and I now have the network options back but a generic IMEI and can't register on a network.
I feel SO close to getting it up and running, but if smartswitch can't help, not fully anyway, I'm not 100% I can be rescued either.

Same here (Think we done the same thing with the Marshmallow 6.0.1 leak) I backed up, but the new version of TWRP I have has EFS as a separate option, I never even noticed and never backed it up.

I've called to my local service center and they said that they will reflash firmware fo 450 CZK (about 17 euros) and It will be done in 1 hour 30 minutes. So I will se what they can do with it. I've tried everything... and right now I don't know what else I can do. But If you figurate out how to fix it let me know Thanks!
Ive also heard that if you flashing each partion one at a time with odin that has fixed it for some

I got 3 old smartswitch backup and i find a file with the imei and everything , do you think its possible to backup this files ?
You CAN recover your phone with smartswitch, there is an emergency recovery function with a IMEI and SN input option, some users who used the same threat (android 6.0.1) and has lost their efs partition reported that smartswitch worked.
I've done this procedure too for some weeks to recover my phone an everything is working fine.
possibly with root explorer

[HELP] No network connection - NO IMEI disappeared

Hi,
Yesterday since I installed CRISSCROSS ROM I lost signal, I thought was a rom problem, after I tried with CARHDROM and the problem persist so I decided to back to the rom that I always use NEXEFY but It don't solved nothing. I checked the signal status, I can see that I don't have IMEI, appeared like unknow.
I have been searching information about this problem, I find a solution using the EngineedMode (Im not sure if this work) but when I dial *#*#3646633#*#* I don't get nothing, I tried MTK SETTING and the same.
I already tried my SIM card in other phones and worked OK, also other sim card of different brand but the problem persist.
Please I hope can you help me.
Sorry my english.

Did you backup efs folder? If not its very hard to revive and im yet to find somebody who has successfully revived their efs. Only thing i can suggest is to flash back to stock in the hope it repairs efs and imei

If you have G925F, you need to flash BL/Modem 4dxxxx.
Try this one by TWRP
