Hey guys,
So I am a beginner here, had no idea what I was doing and somehow I ended up messing up/bricking my S4. Long story short, after several days of messing around with it, I was finally able to take firmware through ODIN back to stock.
The issue is: The phone still does not recognize my sim card, when I check baseband it says Unknown, and IMEI is Null/Null. After further research, it seems that this has something to do with EFS. Unfortunately, I did not back up any such files since I have no real idea what I am doing.
Can anyone help me out with this? Galaxy S4- SGH-I337, NB1.
I just need the most simple fix to get phone working again.
Thanks.
Get a s4 from a friend and make a back up of the EFS. That's how I have heard people make it work
Maybe this can help you.

The only issue with that is they want me to back up and restore the EFS. I did not back up my EFS initially so I feel it is too late for that.

This may be hard, But if I did find an EFS for I337 online.. How would I go about putting this on my phone?
With EFS restorer Express
I thought each phone's efs were unique to that phone?

Did you ever make a nandroid backup at all? I know twrp backs up the efs hopefully you have that somewhere.
There is an app in the playstore that will give you your efs info using other info. It's called meid converter. Good luck.

Unfortunately, I dont think I backed up anything... not that I know of anyway.
What can I do with this app? Am I able to restore the baseband and IMEI?

It will tell you your imei, and other info that you might be missing. From there you will have to try and figure out a way to reinput them manually. There was an app called anycut that worked great for things like this back in the gingerbread days. I'm sure there are ways to do it in terminal emulater now hopefully a more knowledgeable user can help out with that part.
Still cant figure out what I should do here. Any further ideas?
I have tried changing the firmware via Odin several times, and I am still having the same issue! Can someone please instruct on how to get the baseband and IMEI back if it was never backed up in the first place.
Thanks!!

Last bump before I give up on this
Hello. I was wondering if anyone knows how or could point me in the direction on how to fix my efs folder. It seems like it is only half corrupted. I can still dial #*06# and can still get my imei number but every reboot put me in safe mode and some of my apps don't work. I have root explore and I go into efs folder and nothing is there. It almost seems like I have a semi root. I am currently rooted and on a custom ROM. If anyone could help that would be great. Thanks and have a great holiday.

thanks in advance
so I've got a network signal card until I put the sim in.
IMEI, # - everything shows up in the right place. Just no signals available.
No networks showing available.
Anyone??
Check your apn settings. Make sure they're correct for your carrier.

I think this phone is now dead. I need to repair NV, but have no way to do it unfortunately
essentially the phone gets the circle with line thru it. flashed every modem under the sun. not an apn problem. Phone just can see different networks for some reason
problem is NV files, but there is no way to correct issue I dont believe

I feel for you OP, I accidentally deleted my ESF 1/2/3 via service menu (I made a back up via service menu but don't think all the files are there.) A lot of things in my settings are set to "unknown" now. If you find a fix please share it with me, I'm hesitant to try anything else on my S4 since I've already managed to mess it up, but at the same time I guess there isn't much else to lose.

I'll throw in some $ too.
I bought this phone for $50, so even if I can't fix it I'm not out that much money. I'm looking into EFS tool, but since I don't have a back up, I don't think I can restore it.
anyone with efs professional willing to backup your nv file and send it to me??
could try and write over mine and see if fixes signal
nv repair is whats needed. efs professional says not supported

Have you tried flashing stock with Odin?
Have you still got a radio signal (Make calls / text etc) ?
If not, you might have lost your EFS partition, which afaik, needs a professional repair to fix unless you backed up that partition first

Before you try anything, I strongly advise you to backup your EFS partition or you could end up with no signal at all
IMEI and Radios are both contained in the EFS partition, lose that, your screwed

Might be too late if the EFS partition is corrupted and you don't have an IMEI and can't make calls
There are a couple of threads kicking about on XDA S5 forums where people have managed to recover their phones with similar problems, have a read through the Q&A forum and see if you can find them, some fixed by flashing stock, not sure how that worked, but apparently it did
Read others saying they backed up a working S5 EFS and restored it to the broken one
Have a read and see what you can find

so you saying the only thing i can do is to flash a new imei with octoplus or some other kind of boxes.
and if i recover imei from other phone it will not cause network problem becuase there is two phones with the same imei ??
The law in most countries states that the only IMEI number you can use in your phone is the one it came with.....
Nobody here on XDA is going to give you advice on how to change your IMEI for that reason......it's against the law..... *and* as such, it's against XDA rules as well......

First, I have a Moto X style (XT1572) and it has the IMEI as 0! I need help on how to get it back, desperately, please help!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Well, it seems like I have "No service" on my phone, and it says that my IMEI number is 0, and my IMEI/SV is 01. I tried flashing stock rom onto this when it happened. I can't afford a new one and the only way I can keep this phone is if I can fix it - is there any way I can make an IMEI then find the folder to put this back into my phone? I have no backup, but I do have a folder called GSII_repair and it has 2 files, efs_save.tar and efs_save.tar.gz, but I'm not sure it is of any use. I just recognized the efs as the efs folder. I can't find where my IMEI is at the moment, either, so I don't know whether it is completely deleted or just corrupted. I also have a Moto G 3rd gen, I may be able to get an IMEI file from that, and then change the hexadecimals to fit my phone's original IMEI which is on my box. So please tell me, am I completely runined, and my phone is destroyed, or is there a chance that I can fix it? Thanks for any replies. Guys please help me though, I need it!
try reflashing the stock rom, then let me know if it worked. and, btw, its only been 6 minutes as ince you posted.

Thanks so much for the quick reply, I have tried re flashing stock rom back onto my device, as well as attempting to flash many custom roms onto it, with no luck. It is currently rooted, so if I need to access any files I am able to. My dad'll kill me if he finds out, but I know alot about phones and can follow any instruction.

Do you have the box or a sticker or anything with your original IMEI number on it?
posts with bad IMEI are troubling, to say the least..

`fastboot erase all` is the bane of Moto devices, once it has been done if you don't have a backup of the EFS partition to restore you are pretty much screwed and need to get it reflashed by Moto.
I know this might sound a bit weird, but can't he grab an efs partition from another pure with the efs zeroed out and then he can re edit with his imei?
IMEI
I do still have my IMEI on my box, I know what it is. Is anyone out there willing to help me by copying their efs partition and then setting the IMEI value to 0, so I can change it and then put it back into my phone? I don't know, but it might work.
