If you have restored the backup properly, just try to factory reset the firmware...
Which method you had used to backup and restore EFS?

I did not have EFS backup so I used SRS unlock client with UART cable to bring back the original IMEI, now my IMEI and S/N is correct but phone still wont register on network. Any ideas?

I am having the same issue after having flashed the 4.3 version found on Sammobile. SN and IMEI are correct. Have you found a solution?

Please help me too , same situation
previously worked with dlk6 or dll6 firmware/modem on 4.1.2
When I flashed 4.3 Xperia-z1-ized ROM . Device showed correct imei and MK1 modem from the ROM but says "not registered in network "
Have no Idea what went wrong. I have no backup of any EFS or anything .
I installed emergency firmware upgrade via Kies and now running stock 4.3 Android UBUEMJ4 Modem , build number : MK4 Status : offical.
I don't even know if i can root my device with current stock firmware.

Is there anyway to brick the device in official stock state to send it to warranity

I have " not registered on network" problem with my device, after many trials
I reseted the counter and now
I am on 4.1.2 stock rom according to my region which is xxdmc3 >>> and this makes my IMEI incorrect, so I flashed xxdme4 modem and it got my imei Back.
But Still not registered although in "About" : the network information is correct, The name, signal strength, all is okay but Service"out of service"
anyway Now I want to send it to warranty but the problem is that the rom is according to my region but the modem is of different region. I flashed it through odin, it didnt raise the counter but it made device Status " Modified" in "Status" tab
when I flash the stock rom again including its stock modem, the Imei became 009944 fake one
So what should I do..
I want to make it stock with the correct IMEI to send it to warranty
as the counter is official now, is there away to brick it, making it without firmware, So when I send it and they check the counter they find it Stock , in the same time, they can't access to the device to find out that there is different modem???

Try to flash with Odin exactly the same firmware you initially had.
Your IMEI should return then.
IMEI backup is about the very first thing to do before flashing any custom ROM

[FIXED]
[FIXED]
thanks guys for your output i just found this article http://forum.xda-developers.com/showthread.php?t=2088809
by flashing via kies. it will automatically detect your original firmware and what region by putting your serial no only.
i never try to flash other country. i only rooted my phone then using custom ROMs without a problem for network before then decided to go back to unrooted original Samsung firmware.
i think the original firmware is (deutsch) because in the start up setup deutsch language appear. then i set it to English (united states).
my problem now is the WiFi went back off & on. do you have any idea how to fix this permanently without using the code of *#1100#.
because last night i flash the Philippines firmware WiFi working perfectly smooth but no network problem! i think theirs a conflict with the region. if i can only decrypt the file then get the wifi settings. pls help...

SGH-I747M from bricked and no IMEI/ESN to working!

Hi,
After several days trying to unlock my phone and getting it bricked I finally managed to have it in a working condition and unlocked! I'm not sure if what I did unlocked it, but at least it's rooted and in working conditions.
So I decided to share my story and all the steps that I took to fix it. I would have written just the steps but somebody might find specific parts of the story useful.
Original Equipment and Status:
Phone: Samsung Galaxy S3 SGH-I747M (LTE version)
Carrier: Telcel
Country: Mexico
Original Stock OS: 4.1.1
Last working OS: Cyanogenmod 11 Nightly 20141221
Backstory
I'm having a roadtrip that will take a couple of weeks and I got a TMobile SIM to use during my trip through USA and Canada, however my phone was locked to Telcel.
CM brought me some couple of issues with the modem and network selection and as I live right next to the border and cross it every week or so, I was having a hard time switching between carriers and international roaming so I have to upgrade the modem to the latest one (From I747MUMBLL1 to I747MUMUEND3) and for some time I was able to select network operators but still it was locked.
No USSD / Unlock Code Fail
I found on the web there is a way to unlock SG3 for free through the hidden menu, but it didn't work for me but found out USSD codes no longer work in 4.3 so I restored the stock ROM for 4.1.1 (I have no idea how I managed to do this, but got it downgraded) I was able to get to the hidden menu and followed this instructions but I kept using multiple modem versions that aren't for JB the hidden menu didn't gave the option to generate the nv_date file. I think this was due the use of newer modem versions that didn't have the option to initialize the file.
Next attempt was to purchase SIM unlock codes without success, the providers I attempted were TheUnlockingCompany and CellUnlocker, neither of them were able to get me a code to unlock the phone
Also attempted to modify the NV_DATA file but well, it didn't exist in the /efs folder, there were other files but nothing related nv_data.bin. So I really needed to have that file to unlock it but no success in initializing it.
Third-party local unlock dealer
As all the attempts previously failed I needed to have my phone unlocked and was running out of time. So I took it to a local dealer who has more experience unlocking phones. This part I don't have all the info in whatever he did, all I know is that he was unable to work with CM and attempted to unlock it with a brasilian stock firmware, which got it bricked and it was getting more difficult to unlock it.
AFAIK I did have the old bootloader, but his attempts included upgrading the bootloader which includes KNOX and any attempt to restore old rom versions gave me the error SW REV CHECK FAIL : Fused 1 > Binary 0 therefore it was impossible now to get back to stock 4.1.1 and attempt the older modem versions which at this stage found out could have solved the original unlock issue but .... too late.
His attempt with the brasilian stock ROM got the phone bricked and now instead of trying to unlock it I was trying to revive the phone, all my attempts in bypassing KNOX and downgrading the bootloader failed - also attempted to get back to 4.2 and 4.3 through CM 10.1, 10.2 and stock 4.1.1 but bootloader was too recent which prevented me to use those CM versions.
I was able to get it unbricked using CF-AUTO-ROOT - this is a life saver at least to be able to boot the phone, everytime I get a bricked status just by flashing this allowed to boot.
Phone kinda working: NO IMEI NOR ESN
Finally I decided to restore but directly to 4.3 stock for my original provider Telcel. The phone works now... kinda. It boots and gets signal, but NO DATA. I just found out IMEI/ESN information got lost and I didn't have any backup, yes I know I should have but whatever I was doing at least was not touching that information, but this other guy got it messed up.
One interesting thing is that even though there was no IMEI information, but original SIM card works to send/receive calls and SMS. Data doesn't work, but at least calls and SMS does.
Phone included KNOX and was preventing me to use the previously mentioned tool CF-AUTO-ROOT and found this tutorial: http://forums.androidcentral.com/samsung-safe-knox/352922-sprint-galaxy-s3-possible-knox-fix-cf-autoroot.html - this actually works but didn't give me the option to remove KNOX.
THe problem now is that any attempt to use SuperSU through USB debugging was blocked by KNOX but apps opened directly from the phone weren't, with this I installed CWR right away and TitaniumBackup, this last one allowed me to uninstall any KNOX crap. Rebooted the phone and no more issues whatsover in root usage.
As I only have 1 remaining day to have this phone in working conditions and it's christmas today I went on in trying to rebuild my IMEI.
Rebuild IMEI WITHOUT BACKUP
After lot of research and no friends which the same phone that could give their nv_data files, I found out THIS guide (again USSD codes not working so I used EFS Pro to switch USB modes) and basically this is what I did:
Download EFS Professional - Epic tool to work IMEI/ESN info and switch USB mode between MTP+ADB and DEV+MODEM+ADB
Download QPST version 2.7 build 323 NOTE: USE THIS VERSION, NEWER VERSIONS DO NOT INCLUDE RF NV Item Manager
Follow the instructions in the previously mentioned guide, but the USB you can switch it from EFS Pro under Samsung Tools.
It is really important to notice the IMEI number needs to be entered with the HEX checkbox enabled and in reverse.
You probably could do this straight from EFS Professional -> Qualcomm Tools, but this worked for me.
At the end of the guide there was no confirmation or any message the NV information was written successfully, so I just rebooted my phone and success! IMEI is back!
Just to test I tested my T-Mobile SIM and it works! - I'm not sure if this unlocked the phone or whatever the other guy did, but well the phone now accepts any SIM.
No Data / Stuck on EDGE
Now that the phone has the IMEI number and is unlocked I found out DATA still was not working.
I used the tools ESN, MEID and EUIMID Calculator to generate the rest of the missing information which was ESN and MEID. I entered this information in EFS Pro -> Qualcomm NV Tools, checked the boxes and clicked on write making sure the select box next to it was set to Phone.
Rebooted my phone and yes the information was there, however STILL NO DATA.
I came across this life savior - Load this file with NV Item Reader/Writer Some people on the thread say even their already working LTE data achieved better speeds with this.
Rebooted my phone and wallah! DATA and LTE are back! AND UNLOCKED!
What did I learn from all of this? DAMN KNOX and ALWAYS ALWAYS backup /EFS or whatever IMEI/ESN/MEID info is, even if you plan to use custom roms or not, or unlock the phone.
Link to useful tools and sites

sgh-i257 Bell receives notifications but no network connection

I'll try to be brief. lol .Before finding this site I brought my unlocked S4 mini to wind to see if it will work. The guy found the 1700 freq in the phone service menu and changed something and said it won't keep on 1700 then he said something about the nv write. After a while he handed it back and said it wouldn't work. I put my bell sim in afterward it said no sim. it won't find any bell sim now. I tried a friends telus sim and it finds the sim fine and shows voicemail notifications but when I tried to call it says not connected to network. I can see the networks but when trying to connect, the signal drops and phone says "network not available try later". After it tries to connect the signal returns to normal.
So I found this site
I successfully rooted the phone with S4Mini_RootKit_v2.zip. It worked fine but had the same network problem. I fully rooted with cm11, then 12. Same problem.
I loaded a pit file gotten gaciously from sammobile. Same problem
I've returned all firmware to factory and undone root but still same issue.
The imei and serial number match the sticker on the back so they are not invalid.
The wifi and bluetooth and general operations are normal.
I'm guessing that the nv was rewritten and to recovery as well? But I really don't know as I am very new at this but have been doing a lot of reading.
1. Is there a way to restore the nv without a backup from my phone?
2. Is there a way to restore the service programming back to factory default? (I've seen this question asked before but only found the answer it is proprietory, whatever that means)
I have qpst and efs professional and a qcn file I was able to download from the internet
3. This qcn file is from unreliable source. Could I damage my phone more than it already is, and can i edit my imei and sn into it?
Thanks very much.
