Everytime i try to install a MG4 / MG6 ROM i get the serial number messed up and IMEI. I have to go back to a previous and use ariza patch bc of the problem with the efs folder. I even flash an MG4 Baseband, but still no luck. How will i be able to install an MG4 Rom but without having the efs problem? O knoe EFS folfer has a new format but how can i make mg4 rom recognize that new format?

MG4 ROM changes the format and MUST be accompanied by an MG2 or MG4 baseband.
If you have flashed Ariza patch though, all bets are off.
How are you flashing? Via Odin?
It sounds like your efs folder has been damaged previously, ariza patch doesn't repair the imei number -nothing can do that.
Try restoring an earlier backup of your efs folder (the one you made before you ever flashed anything) before flashing the EMG rom.

once you flash the MG4 firmware, do not flash any older f/w-s. back up efs once you flash MG4 or later f/w-s. hope these threads help you: http://forum.xda-developers.com/showthread.php?p=43966399 || http://forum.xda-developers.com/showthread.php?t=2393289

I flashed via CWM. since i flashed it i have problems with IMEI and SN, i restored my EFS folder now i have signal and sn still shows like 00000 but i have 3g and voice calls. When i flash an MG4 firmware i lose voice/3g. Even with MG4 Baseband.

Ariza only fixes SN. You've obviously got an issue there. I'm not sure what to suggest other than flashing full stock via Odin.

full stock MG4 and then root to instal custom rom?
OR should i stay put with UBELL6. Will it protect me from the sudden death?

If you have now, a backup of EFS BEFORE MG*, I would try and flash full MG4 via ODin. Hopefully it fixes. If not, root and restore EFS and go back again..

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.

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.

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

Hey,
I flashed stock firmware on my S3 with Odin. After that it doesnt read my sim! It has no baseband and no Imei number when checked.
I have always been on official firmware, so i have no backup of my EFS partition.
I have tried to get in to the service menu via the dialer, but it doesnt come up.
What can i do?
There is a method to restore An automatic backups of the EFS folder.
The phone should be able to rebuild it from there.
Just Google for it

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.

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?

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
