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

Hey Guys,
So I had my usual SIM card working as usual on G4 stock 4.1.2 firmware. I later on flashed CM10.2 20130814 Nightly build after which my phone was stuck on Emergency Calls only. I flashed three different stock 4.1.2 official firmwares after that but nothing seemed to fix it. They recognised my SIM and carrier though they weren't able to make calls and whenever I tried to it gave me the error message "Not registered on Network".
It is a fully unlocked i9300. I would really like your guys help on this.
Questions go in the Q&A forum, report your post and ask for it to be moved.
Does your IMEI number in phone match the one under the battery?
Did you make a backup of your efs folder like all the guides recommend?
If your IMEI has changed and you don't have a backup then flashing the latest full stock via odin on your pc sometimes enables the partition to be read again.

Well, This is the Q&A section. Anyways, I didn't make a backup of EFS. I tried flashing stock as mentioned in the OP but it didn't prevail so what should be the next line of action? xD
Hah! Sorry, my browser took me back to q&a from general.
Does the IMEI match?
If not then you need a repair.
I am currently back to flashing another stock firmware so didn't check. If it doesn't match then what sort of repair would it need?

For anyone who finds this thread.
Problem: /efs partition format changed
The latest 4.1.2 UK (XXEMG4) and India (XXEMG5) ROM releases (Which come with MG4 and MG2 basebands respectively), actually change the format of efs.
If you have flashed a, XXEMG4/5 ROM at any point, you are now in a situation whereby only an MG4/2 baseband can read the IMEI in /efs. The new efs format is not backwards compatible with older basebands. Probably, all new basebands will be compatible so in time this issue should diminish I expect.
If you have ever flashed XXEMG4/5 ROM, to keep your IMEI working, you must:
Stay with the basebands MG4/2. You may flash other ROMs but must return to the MG4/2 baseband.
Restore your efs backup (taken before XXEMG4/5 ROM install) to use older basebands.
Please note, it is flashing the ROM that alters efs format, not the basebands themselves. You can flash the MG4 or 2 baseband safely on their own and return to an older baseband without issue.
You can download an MG2/4 baseband package HERE
Aroma installer, choose between MG2 and MG4 basebands
Basebands alone do not alter efs format
Backs up EFS in an uncompressed format (Use Root Explorer to restore)
Does NOT include RIL, works on AOSP and Sammy

NO it didn't work as i installed the latest firmware through odin, and then get OTA as well but it didnt solve the issue, then i installed the MK6 BTU firmware but it didnt work as well.
tired of installing the ROM's and Patches but non of them worked, is there any posibility to get it in working condition or should i use it as IPOD???
Take it to a repair centre and pay them to recode it, make sure it works on 4.3 firmware before you pay them.
Patches are a work around for modified efs problems, a corrupt or wiped efs can only be solved by professional repair.
SOLUTION:
Flashed this patched modem:
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.

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 have just 2 or 3 simple questions. especific quesitons that i cannot find the answer on your post. or maybe the answer is on the next 11 pages? you mention on your post only MG4 roms or newer. don't say anything about Mh2 . so the questions is kinda easy, would i am able to have signal and imea read on a 4.1.2 if i flash a mg4 modem after install ? . and same thing happen to 4.2.2 or 4.3 will i have to always flash a custom modem to have my imea readden?

I've got this fragment you wrote.
"If you have ever flashed XXEMG* (or newer) ROM, to keep your IMEI working, you must:
Stay with the EFS v2 basebands (MG* or newer). You may flash other ROMs but must return to the MG* (or newer) baseband
Restore your EFS backup (taken before XXEMG* or newer ROM install) to use older (EFS v1) basebands. EFS backup must be an EFSv1 backup to use an EFS v1 baseband
If the above don't work, consider sending for repair... "
SO i will have to back up and restore the mg4 mh2 efs every time i want to change rom for a older one.. do you know if 4.3 (as it will be obviosly new) will have a mg4 or mh2 mh1 modem? . im kinda having problems on my calls . internet and messanging are just fine . but some times when i want to call the automatic operator says " the call could not be proccesed" but dunno if this is a signal problem or it is just me.
does k tools back up v2 efs?

why don't you try to just update your firmware to 4.3 (choose 4.3 stock roms) to quickly fix those issues.

go into settings - about phone - status and look for your imei. if it is 0049... or 000000... then read this: stickies for efs
also some more information would be helpful:
how did you get the 4.3 firmware (odin, OTA, or custom rom/recovery flashable zip) and how did you revert back to 4.1.2 (odin, custom rom/recovery flashable zip)
so either you corrupted your efs, what would only be fixable by restoring an efs backup or you have an efs v2 and now you flashed an efs v1 modem which are not compatible together, what would be fixable by flashing a modem later then xxemg4 (read the sticky thread to know about what i am talking)
edit: ok I hope the above solution works for you
I updated 4.3 from Kies and back to 4.2.1 from odin. got firmware file from sammobile.com. (I9300XXEMF6 )
I am not really IT person. but if i get step by step guide, I can do it by myself

well then probably the flashable efs v2 modems from the link of @tallman43 will help you.
by updating from 4.1.2 to 4.3 your efs was updated to v2 as well as your modem. Now you reverted back to 4.1.2 through odin, your efs stays on v2, but your modem has downgraded to a modem which is not compatible with efs v2.
so if you flash now again a modem which is compatible everything should be fine again. they can be flashed through a custom recovery.
but please read the efs stickies thread (and maybe also all the other stickies threads) and make an efs backup as there described.

Never mind off topic question
What if I install 4.0.4 stock BTU rom on my s3 gt-i9300. Will I be able to get my network back again by flashing one of these roms?
Thanks in anticipation
