I was running the cyanogenmod installer version and then tried Android Revolution 51.0 and upon flashing back to Cm I lost service.

Restored the backup and still nothing, I'm sure that this backup worked for me before as it's about 3 months old.
Efs v1 will only work with firmware prior to EMG4, efs v2 works with EMG4 and later. Depends on your backup as to which firmware you need to start with.

Is there any way of finding out which efs version mine is?
Only by trial and error.

Try downloading and flashing the latest modem available for the device through Odin.

After flashing a modem I had no network. I've checked and I have no IMEI. When I type *#06# the box is just empty.
I already restored an EFS backup I've made, and the EFS folder seems ok.
Also, the modem I flashed was the stock one.
Do anyone have an ideia of what can I do to recover my IMEI?
I think you have installed the wrong Modem driver, try to get the official one from other sources and try again.

Nope, it is the correct stock modem. I also reflashed my previous one and it still has no IMEI.
Modem has nothing to do with a lost IMEI .
Restore backed up EFS and or factory reset .
Fails try a stock rom flash .

Yeah, but I only lost IMEI after flashing the modem. I had flashed modems before (even this one) and never had problems, so something must had gone wrong.
Already restored a backed up EFS.
If I don't find any fix I guess I'll try a stock rom flash...
Type *#1234# and see if baseband is unknown. If so then flash another modem.
Another thing to check is that if stock samsung dialer is not working imei will say null.

Incorrect. If there is no modem installed, it will not report the IMEI number.

If you have flashed the EMG4 rom you should check the topic in General section

i dont have a efs back up.
Assuming you didn't flash EMG4
1) restore backup. No backup?
2) try return to stock (complete unroot). Still broken?
3) send for repair

Do hard reset with buttons, then use KIES emergency recovery and hard reset again. When I messed with some custom ROM happened me the same. I think 2 or 3 times I had to use KIES when finally was ok.
Also use KIES and tick allow storage and then click Update unsuccesfull. You'll get a recovery code within KIES. Use that code for recovery. If still fail, you can send it in stating that update damaged your phone.
i send it to repair service and they restored the EFS Folder.
Everything is fine now.
Hi there.
I have a ROM backed up via recovery and I am pretty sure I have backed up my EFS as well.
However upon restoring my phone to stock, I noticed upon boot that I had the generic IMEI number (004999010640000) and have been unable to make calls etc.
Upon noticing I had to re-root and install recovery (PhilZ Touch 5, CWM Base version: 6.0.3.3) to restore the ROM and hope it restores my IMEI which it didn't, next I looked for my EFS in a folder called EFS_Backup and in there is 'efs_05Aug2013-2257.tar.gz" however it appears to be empty.
I don't know what to do as I am out of warrenty and I thought I completed the steps, theres no .bin or .img files I can find.
Any help will be appreciated.
Thanks.
You have to restore it using custom restore from philz

you said efsBackup.tar.gz is empty so which means its 'bad' backup . so obviously it won't work.

Looks like I am f****d then
How big is the .tar.gz file? It should only be 80Kb
If zero size then yes, you are screwed unless flashing a full stock 4.1.2 rom via odin makes the efs readable again (make sure it's an EMG ROM if you've EVER flashed an EMG rom to your phone)

Just an update, I managed to get my IMEI number back by flashing the MG_Basebands.zip, however the altered EFS seems to affect the GalaxSimUnlock from working as it says the phone is "Unlocked" when it's locked to Three UK.
I am just glad the phone is working.
After having S3 for some months, I decided to update it to 4.3.
So I searched online and saw some tutorials how to root and install costum ROMs.
I read few tutorials to be sure how to do that and after all went good and the ROM installed, One problem has rised: NO SIGNAL!
so I wiped all and installed a ROM STOCK.
After that the signal came back "half way". It's showing signal bars but I can't call to anyone, even after calling to my provider...
I just don't know what to do. Please help

well these tutorial you've read were either very bad or you haven't read them correctly, because probably you missed the important step of the efs backup. see therefor the stickies thread or the thousands of similiar questions here in the q&a.

That is your backup flash with odin
( When you flashed a custom rom it probably backed up your efs some roms backup by default)
I would just backup your efs you have at the moment just in case you have problems flashing. You will then be able to return to how your efs is now even though it is not fully working..
Or try this app >> https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool <<
The phone has to bee rotted to use ktool?
I also understand from the link you did about the EFS that there are two types of base bands and if I have an efs backup that I did on V1 baseband so I can't restore it on a v2 baseband, so my conclusion is to get back to 4.1.2... correct me if I am wrong

good that you found efs backup
yes you need root. or you use the recovery philz touch to restore your efs (then you don't need root, but a custom recovery).
well samsung roms based on 4.3 need efs v2, so you have to go back to 4.1.2 to restore your efs v1 backup.
if everything is working again, I would suggest you to use oding to upgrade to 4.3, because then everything should be updated correctly (but keep your efs backup, and make another one, just to be sure)
then you can try out again custom roms based on sammy 4.3
So what is the best option to restore it?
Because before I tried (while 4.3 stock rom was installed) the flash it with Odin but Odin always crashed when I was uploading it to Odin.
With kTool I tried before but when I am clicking on the button it says that it restored but he didn't asked for directory, when do I need to put it?
The same story with phliz, I also tried with this and he don't asks for directory, only asking whan the ending if the file-tar to bin...

Just extract the efs.tar and copy its contents to /efs.

Where is this folder located? I can't find it
and does it for xTool and phliz recovery destinations for teaking the recovery from?
Edit:
I found the /efs. I dind't know that I need to use root explorer...
I exchanged the files with my back up and suddenly instead of 0049 IMEI I got 0000 IMEI.
I tired also to flash a modem and also didin't work...

Hmm... try installing another EFSv2 modem, then do the /efs copying part again.
Suddenly after so restarts, the IMEI got back
But... The SN now is 0000000000
You'll need to correct the permissions of the files you've copied. Try searching for someone who already did this and duplicate what they did.

Ok,
I tried something new. I flashed a new modem, backed up a full backup and then installed a costum rom 4.3.
the IMEI GOT BACK! And even the SERIAL NUMBER!
But I think the serial number is not good because he has 16 or 17 (I don't remember) digits (numbers and letters).
But still i have signal bars but can't make or receive calls he says: "No registered on network"
For the finalle, I tried ARIZA patch but he Is stuck on 0%...
here I stopped, I really don't know what to do.
Don't use the Ariza patch once you've got your IMEI and SN back. Maybe try flashing a new stock version of Android with a EFSv2 baseband so as to not go through the copying fiasco.

Hello everyone! I've lost my EFS and want to restore it, but i didn't make a backup and don't have any Z3X box and other...
That's my ask: please, can you make efs for IMEI 353314/05/548065/9 and S/N RF1D386WBOX and make backup or zip for PhilZ recovery 6.58.7? If you want, i can pay for this by paypal, but not a much)))
P.S. Sorry for my bad english.
Hi first tell us what you have done and lost your efs maybe we can find a solution

Well, i install cm12.1 by archi with wipes, kernel wipes, installing boot by archi but I didn't make a backup efs(only system, data, cashe and modem). I'm using PhilZ touch.
I don't have a Z3X box, so i can't restore my efs. In my town has no any service-center for phones and i can't buy z3x box because it's too expensive for me(1$=50 RUB). Maybe we can do like that: install efs with my IMEI and S/N to another I9300 phone with I9300XXEMG4 modem, then backup efs or make zip/tar for installing efs by Odin or recovery?
First try to go back the original version you had before cm12 and see that if your efs is intact. Do not think z3x box everytime you fail with the efs partition. It is the last thing to do...
What version was installed before cm12?
I almost did it and now my IMEI is 0049... and S/N is another
Maybe there is still valid nvdata.bin.bak in efs to restore?

I9300XXUGMK6 or I9300XXUGNA8, which better?

Oh, i forgot about one thing. IMEI and S/N is wrong, but i can switch acces point names and newtwork operators, but i can't call to anyone and USSD-codes isn't works(like *100#)
If you installed 4.3 and this happens then search for "patched modem and kernel for 4.3" and try to install them and see if you can call
