Hey guys, I'm having a huge problem with my GS4,
I have flashed different roms, and now, my phone won't recognize my sim card.
I've checked my settings then, to see if my IMEI is still there, but it isn't.
I thaught okay, I have a TWRP backup of my EFS folder, so i went to restore that, but the IMEI its still unknown.
Can I somehow extract the EFS folder manually from the TWRP backup, or restore my IMEI otherhow?
My WIFI is still working with no problem at all.
Also I do not have an nv_data.bin file, but a working TWRP Backup.
Thanks in advance.

Thanks for your help, fixed the problem myself, the TWRP Backup was corrupted.
Backed it up again. :good:
Hey guys, the problem appeared again,
after flashing the Gummy Rom, and the IMEI Backup in TWRP, the phone was working fine, until today, when the IMEI disappeared again.
So I flashed the Stock Rom and the IMEI again, and it worked. But after approximately 2 Hours, the IMEI was gone again, and even the re-flash of the Stock Rom and the IMEI backup, the problem has not disappeared.
Does someone know how to fix the random IMEI disappearing or has faced a similar problem?

Magic DEVICE Imei and Baseband restored but sim card DIE
You have to reflash a GB-Rom,i.e. JVU. Then everything will be ok. And after that flash a ICS-Rom which not makes disappear the IMEI and then, without wiping you may flash this special ICS-Rom which caused that issue. Now everything should be ok. That was the experience I have made.
I lost efs together with imei last week when I tried to flash a different modem. Running out of options I sent the phone to a repairer.
Today, after one week, I picked it up from them and they somehow got the imei back and the phone is working while I was still at their office.
Now I'm home and tried to connect it to my home's wifi, as soon as it connects, the phone reboots. It's very stable on mobile data though.
I cleared data, flashed different roms, but wifi connection always reboots it.
Then I looked in the efs folder and surprise, it's empty!!! I don't know whether that's the cause of the wifi problem, but isn't it odd that the phone runs ok otherwise without efs?
Anybody has any idea of what's happening to my phone? Can my wifi problem be fixed?
I do actually have an efs backup that I've done back in January. But I just can't remember what tool I used to make that file. The file name is "efs.img". Any suggestion at all?

No, under absolutely no circumstances should anyone give to you their EFS information/backup. It's illegal for a start. You should have made a backup of your EFS, you're going to have to send it for repair.
^^This, exactly.
Thread closed.
hi my friends, i hope you could help me with this, im having a strange problem,i bought a note 3 n900 second handed with this problem, it has imei null and baseband unknokn, i sended it to repair store but they solve half of the problem since now it shows the correct baseband but still imei null, is there anyway i can fix this ? (see attachments)
i must add that since i bought it had that imei null thing, so i have no efs backup, anyway i saved its EFS folder backup when i first started to mess with it, but when i try to restore that EFS the problem persist. I think maybe the efs folder was already corrupted when i bought it.
thanks any ideas would be appreciated.
they just flashed the right baseband maybe but there is a problem with the radio chip. it's just a tablet and there is no legal way to recover your imei i am afraid (other methods involve using an unlock box).
You got any solution

Thanks for response. Can i recover from memory card? When i installed custom rom, it will backup efs automatically. Which recovery is best? Dr.ketan...voilla...etc. I didn't understand. What is that?
Custom roms do not back up EFS.
