hello, everyone.
I was on 4.3(Jelly Bean) and somehow I've got a virus so I though I will re-flash it and start from fresh.
I used Odin3 v3.04 and flash it to 4.0.4(I9300XXALE8_I9300OXAALE8_BTU) and then my imei number has been changed to 0049....
I have tried few guides online still the same.
I did not backup my efs so I don't have any backups, can any one please help.
thank you.
Flash 4.3, your efs is incompatible with such an old firmware.

This is from the Omega thread OP..
1. Make sure to make and keep in a safe place an efs backup - nadroid backup - titanium backup - etc, in case you ever need to restore!
2. With the new firmware from Samsung for the S3 they have changed some security code that will disable the use of older modems, the new update changes the EFS partition which makes it impossible for an older modem being use without upsetting your IMEI (No Phone Signal), please make sure you do have a backup of your EFS in a safe place before you flash to the latest Omega ROM.
This is what Samsung has done, and it seems that its being done to all the new Modems on all the high end devices.
More info
3. Flash with No Full Wipe only from v43.x and previous Omega 4.1.2 versions - if

Code:
http://forum.xda-developers.com/showpost.php?p=45038238&postcount=466
Now back to network
Also PLEASE BACKUP YOUR EFS!! BACK IT UP!! ASAP!!
I flashed a MG4 rom and after that the imei is changed. I do not have efs backup.
The IMEI has been changed to a new one and the mob is showing emergency calls and not registered on network.
The Serial Number has changed to 00000000000
I cannot make calls or text other than that the mob works ok.
The imei was 353xxxxxx and now it is 3591xxxxxx
Can anybody help?
Also the rom was sammy not a custom rom so i got no backup of EFS.
I tried using MG4 baseband but same error.
Ariza patch simply nulls the imei and hence not working for me.

If your rom comes with a modem, you'll need to reflash the patched one. Otherwise, no action to take.
Thanks alot!
I am glad that my device is back in life

Out of interest, was it simply from this post:
http://forum.xda-developers.com/showpost.php?p=45098088&postcount=476
You flashed?
Edit > I see you updated OP and flashed specific modem.
Yes i flashed the patched modem and the network is back online and up until now the phone seems pretty good and batteryl life is excellent.
Also I am on stock JB firmware for now.
I'm having the same problem. Did you flash modem by downloading and pasting into an sd card and then by using TWRP on your phone?
I've got the same issue, was running on stock 4.3 and flash a different stock rom on it , lost my imei and baseband now am stuck with no network , looked for solutions all round but non is working .. didn't back up my EFS too . Can anyone help with this ?

Depends what you mean by "different stock rom".
If you flashed backwards to 4.1.2 then your efs isn't damaged, it just can't be read because the encryption keys changed at 4.3. You cannot downgrade without an efs backup from 4.1.2. In that case you should be able to flash back to 4.3 and your efs will be ok.
You can also try kies emergency recovery. Depending on your os depends on which kies (2 or 3) to use.

I hope you have an efs backup. if not follow the steps in the linked thread.
btw which 4.1.2 did you flash. when you flash 4.3 rom efs will change to v2 so you need a rom with efs v2 baseband (everything newer than xeemg4)

yeah I know but which one (the build number) something like XXELLA or XXEMG4...? you can see it in settings menu
in fact if you have flashed a firmware older than XXEMG4 then also its baseband is flashed, and these old basebands are not compatible with efs v2 which has been flashed through your sammy 4.3 update.
This could PROBABLY have caused your imei problem and you would only have to flash a baseband newer than XXEMG4 to PROBABLY solve it. or your efs is corrupt than you should follow the steps in the stickies

Hi,
I just upgraded my Galaxy s3 (i9300) to 4.3.
I hate this update, I want to go back to 4.1.2
Can anyone please help me with a safe method to achieve this..
You can downgrade using Odin. Get your preferred stock ROM version from www.sammobile.com, then flash it using Odin to the phone.
Just a word of advice, get a 4.1.2 firmware with mg4 baseband or higher to avoid efs and imei corruption.

Thank you for your response. I have attached a screenshot of the version I selected from sammobile.com, kindly check.
I checked online and found that downgrading from 4.3 could corrupt the EFS and IMEI as you told.
In order to backup these I need to use EFS PROFESSIONAL (which requires root, but mine isn't rooted.)
I have a question. Like you said I have selected the most current version of 4.1.2 (in which PDA says : I9300XXEMH4) released on sammobile just before the current 4.3
Can you kindly confirm if I can proceed without rooting my phone in order to downgrade it to 4.1.2 ( without running into EFS or EMEI issues)
In other words, Can I proceed through odin and downgrade to 4.1.2 without any EFS issues with the firmware version I have selected?
I really appreciate all your support, please help..

You can always flash a proper modem if you mess the IMEI up. And the version you selected looks ok.
Hi,
I've encountered a problem today. By mistake i have restarted my phone after the wipe, and soft bricked my phone. Then I tried to flash to stock with odin and after a few tries managed to do it But the problem is, after the flash i've got a "selected network unavailable" notification. Tried many things, different stock firmwares, reinstalled many times, but to no luck. After that i've installed aospa and tried to restore my efs backup, but that didn't help either. My imei is intact and in download mode my model is shown too.. What can I try doing to make it work? I can provide any information you ask.. My model is I9300 International. Baseband version in "about phone" tab is: I9300XXEMG4, the stock rom i've installed is as shown in *#1234#: PDA: I9300XXEMG4 CSC: I9300OXXEMG3 MODEM: I9300XXEMG4
Go read the sticky thread on efs in general forum.
If your efs backup was made when your firmware was older than EMG4 then you need to downgrade to the old firmware before you restore it, as efs format changed at EMG4.
Both the imei and serial numbers are required to obtain network.

I have both imei and serial correct, but how do I check which baseband I made the efs backup on? Because I don't remember..
Your serial and imei is ok.
So I think you should flash a patched modem matches with your firmware

You have just saved my life. Indeed flashing patched modem matching my firmware (UGNA8) after flashing Boeffla-Kernel on stock helped regain my network Connection. May it be a remainder of how easily you can mess up your phone
So officially, problem solved.
