Unless you have an efs backup, or flashing an EMG modem enables your efs partition to be read again, then you are basically screwed and need a service centre.
Hei,
I was running 4.3.1 Dirty Unicorns and wanted to flash Smartdroid.
So, flashed Devil recovery and tried to flash the ROM.
It gave me message that there's an error in the zip file.
I was just playing with the options available in the recovery and selected some option, which I don't remember now.
After that, the went into bootloop. "Samsung Galaxy S3 I9300" appears on the screen and the phone reboots again and again.
This loop continued.
The phone could be put in Download mode.
Then, I flashed CWM 6.0.4.4 and flashed 4.1.2, which I downloaded some time back.
It went on well. I could boot the phone and had set it up.
However, I couldn't connect to network.
The IMEI was some default one.
Rooted the phone and tried to restore the backup of efs folder using HC-Ktool.
After restore, when I booted the phone, it didn't boot.
"Samsung Galaxy S3 I9300" appears on the screen and the phone reboots again and again.
I tried flashing the ROM again, CWM again etc etc.
Nothing worked.
In one occasion, after installing CWM 6.0.4.4, I restored from NANDROID backup. Restore was successful.
But, it wouldn't boot.
Same "Samsung Galaxy S3" appears on the screen and the phone reboots again and again.
Once, I flashed Dirty Unicorns ROM from zip via CWM. Still the same.
What is happening and how to solve it?
Any help is greatly appreciated.

Wipe Data/Factory Reset -> Download mode
Flash latest Android 4.3 from Sammy through Odin, preferably XXUGMK6 or newer.
Hei,
This worked!!!
Thanks.
Why flashing 4.1.2, Dirty Unicorns didn't work and this one worked?
If you can explain, that will be helpful to all.
Now, though the phone is booting, the efs folder is corrupted.
IMEI number is not what it should be.
I have a backup of the efs folder taken using HC-Ktool long back.
So, the ROM on which efs folder was backedup will be different that the ROM I have now. (Does it make any difference?)
Can I just root and restore that efs folder using HC-Ktool?
Thanks for the help!!
Regards,
Babloo
Edit:
If I flash CWM Recovery 6.0.4.4 and restore the NANDROID backup that I took before I started screwing my mobile, will everything be fine?
Sounds like you tried to flash a corrupt file, always check the md5 before you flash.
EFS is totally separate to the rom, format the partition, restore your backup then factory reset should return your imei on the current rom.
Nandroid will not fix the efs, unless you used a custom backup process that included the partition -the default settings would not do this.
Hei,
"format the partition, restore your backup"
For this, can I just root the phone and use Ktool to restore backup?
If you suggest any other procedure, pls give me more info.

Hei,
After the previous post, I could restore my phone from NANDROID backup that I took yesterday, before the whole mess.
After that, I tried to restore the efs folder using HC-Ktool from efs.img.
It gives the message that restore is completed.
But, after reboot, the IMEI remains the same wrong one (the generic 004999...)
The size of efs.img is 20.48 MB.
I tried to restore using the terminal method.
With the command "unmount /efs" I get error message "sh: unmount: not found"
How can I restore the efs and get back my IMEI?
When I tried to "open" the img file in Windows, it couldn't open. It says that the file is corrupted.
Could it have been really corrupted or it is just that Windows is unable to open it?
I restored the efs using the same backup file.
Why is it not working now?

You are trying to skip essential stages and hurry to finish, but your partition is still corrupt -you can't restore anything to a corrupt partition.
Search and read someone who has succeeded doing the same thing, follow their guide exactly.

I have been searching for a proper procedure to format the efs partition since your post.
Whatever I found didn't work for me.
Can you please point me to any post that you know?

Hello, I'm new member in here. Today I flashed UltimaROM to my SGS3. Before the flashing I installed Philz touch recovery and saved Nandroid, modem and EFS backups in my PC. After the flashing no IMEI number was shown and I got a message saying " Insert SIM card....". So i tried to restore EFS in custom restore option in philz recovery. Even though it showed restore successful , IMEI number is still unavailable and i couldn't connect to mobile network. I also tried ktools to restore efs but no result. Can someone please help me regarding this issue.
What version firmware did you have before you first flashed? If it was really old then that could be the problem.
Flash a 4.3 stock rom, factory reset them boot and see if your efs is read again.

Thanks for the reply. I had 4.1.2. If I flash 4.3 stock ROM can i retrieve my IMEI ?
If you flash a 4.3 stock it will update your efs to v2 and should enable it to be read in all newer firmwares.
Hello,
I've backed up my EFS with TWRP 2.8.6.0 but when i rebooted my phone it said that i had no service.
What to do? Want to install Liquidsmooth rom but i'd like to still have my EFS so i don't lose my IMEI
PS: I've flashed my rom to stock again, i can make calls again. But i still want to backup it and install the rom.
Thanks in advance!
Makes no sense, to backup efs just copy the whole directory to your pc -only requires root.
@ha966: you lost your IMEI probably because TWRP 2.8.6.0 was to big, it overwrote some neigbbour-things and flashing your modem again had repaired it. The corrected version 2.8.6.1 is online now.

Yes this is correct, found out the hard way. Happened to me aswell
Flashing stock rom with odin fixed mine, but i did have efs backups anyway
Try flashing stock first before trying any efs restoring
I was downgrading from CM14 to OrionOS MM and now i have lost my imei and baseband. I tried the efs recovery guide but i am not able to restore imeis. And my wifi and bluetooth are not working too. Please help.
I made a backup in twrp but restoring it doesnt give me back the imei numbers. What should i do now??
What happened with me is just this case- http://forum.xda-developers.com/red...ion-firmware-failed-to-restore-t3404901/page2
