Ok I notice that a lot of people are losing there IMEI flashing the great MTD Roms well I have had that problem & also by me losing my IMEI I had the volume bug where when I call someone or they call me I couldnt hear them but had to press the volume button. Hopefully this will keep the threads clean of this problem. To check for your IMEI on your dial pad press *#06# if all 0's come up you have lost your IMEI.
What is Efs?
thomas.raines said:
Efs is the files system that holds the unique identifiers for your device. Without it, your phone is basically useless. You won't be able to connect to any network properly do things like phone calls, internet, texting, are all degraded, if they even work at all... Make sure you know what you are doing before messing with it. Fb created a vet good guide on the wiki. Follow it to a T!

Ok now in order to restore your IMEI you will if have go back to stock KJ6.
You will have to use this http://forum.xda-developers.com/showpost.php?p=21953878&postcount=2 this is lumin30's Guide on how to use the KJ6 Heimdall One-Click 1.3.1 by bhundven it works after I used it my IMEI was restored and I didnt have that volume bug anymore. Also you will if you dont know how to put your phone into download mode this is a way how remove battery, hold volume up and down, plug usb cord into phone (make sure its in the computer first), and insert battery u will see a yellow triangle with an android.
Now once you restored your IMEI backup your EFS to your sdcard and computer because you might need it again I lost my EFS twice I was so glad that I had a backup. I hope this help.

Not sure how I pulled this off but it may be an option for some with this problem ( lost IMEI ). I flashed from Antonx's modded stock ROM and had all 0's for my IMEI. Well being that I work at a place with no usable PC, I thought maybe I could pull my efs from a nand. Well since I am very green at this stuff I didn't really know where to look. Common sense said to look for a cwm folder,but no luck. Anyway saw this file sdcard/backup I opened it and behold efs so I copied and pasted to the efs file and rebooted. Bingo! My IMEI is back to normal. Like I said not sure how the backup got there but it worked. Hopefully a dev will see this and shed some light on it, but for now it might help someone without access to hiemdal.
Oh yeah I used root explorer.

Just copy the files from the backup efs folder to your empty efs folder which should be on the first page that pops up when you open rootexplorer.
I didn't see this till I had fb tell me what to do, I did a one click then did cm7 then aokp and all worked. Must let cm7 build and wipe the systems before flash.
It had been a long time since I heard Linda speak.
All works now.

Okay, so I've been pretty flash-happy the past few days, especially with the release to UCLD2 and stuff, but after the last few flashes I've noticed that I've lost my power menu and my lockscreen does not activate. I've already searched around and tried many methods of fixing it, but I may have been digging my hole deeper...
I've tried pasting keystr into /efs/imei, but no for some reason when I try creating a file in /efs/imei in Root Explorer it doesn't even show up...
I also tried using the terminal method, but whenever I type the line "echo -n ON > /efs/imei/keystr" it returns an Input/Output Error.
I'm really confused on what to do, files seem to be not appearing where they should be and I'm kinda worried, I like this phone so much! If anybody can help me out, I'd be greatly appreciated, and I can provide any files/info that is needed.

It was already said in another thread that I read that ODIN and CWR do not touch the /efs partition, thus making it useless to ODIN restore.

That was from the note radio when that happened to you?
I had flashed the note radio, since I was having trouble with UCLD2... That's probably what did it. I'm gonna give icenight's method a shot and see how it goes.

Hello,
I'm kind of frustrated now, because I cannot get my IMEI back, though I have EFS backups, and do not get any errors.
I was using CM7 before. Everything was fine, except the KJ6 modem, which worked bad where I live, and that drained the battery. So I decided to go back to a BML ROM until it's possible to flash modems in CM7.
I used a 1-Click to get back to stock with CWM. It went fine. Then tried to flash Erik's MIUI. And for some reason it started bootlooping (this did not happen before).
I finally un-bricked the phone using Odin. But I found out I lost my IMEI. Have no idea how this happened. The EFS folder was there, all files too, but no IMEI, no baseband, no calls.
I had a backup of /dev/block/stl3. So I deleted the /efs contents and flashed the backup with Heimdall: "heimdall flash --efs efs.img" I got no errors, and the EFS folder was populated with files. But it did not help - still no IMEI.
I decided to go back to CM7 then. I installed CM7 before, and it worked fine. So I did everything as before, restored EFS, flashed the update. And got no IMEI in CM7 too.
I did it again, restored EFS, flashed update, even fixed permissions, but nothing helped. I got no errors when flashing, and still no IMEI afterwards.
I'm kind of tired of trying now. Would appreciate any help. Thank you.
Reflash your efs backup shutdown and pull battery. Hold the power button for a few seconds to drain leftover power and let the device sit for 10-15 min without the battery or power. This should reset your hardware.

Amazing! It worked! I've got IMEI back in CM7 now. Thank you so much!
Would it work now in a BML ROM too now? Or would it require doing the same steps? It's kind of scary to check, I don't want to loose the IMEI again
What you did is reset the hardware programming (in the micro chips) the same way a computer would if you forgot your bios password or something. Should work the same on bml.

Thank you so much Bassmanjames. Seriously, thank you. Helped me tons.
Ok so I got a little flash happy today and during the course of it I messed up my IMEI to all symbols. I went and reflashed everything about 10 times and tried to restore my efs backup from my card.
I guess that my efs backup became messed up because none of the times has it fixed my IMEI like it has in the past. I have another efs backup on the sd card and I remember reading somewhere that I can manually push the files.
I just cannot figure out what to push to restore the IMEI back to normal. I have pushed the EFS backup tar and got data back but with my IMEI still all symbols.
Can anyone tell me what files to push? I would greatly appreciate it
Have you flashed the efs_restore zip? I think there is a method posted in FB's unlocker thread.
Yes I have tried flashing the efs_restore zip so many times. I have no idea what happened on why it is not working. I have tried every MTD rom to date and I have always used the restore without an issue.... until today, when everything just stopped working. I do not get any errors during the restore zip and it appears it works until I boot my phone and check my IMEI
Maybe you just need to go back to kj6 via heimdall.
If you have a backup if your efs (the efs folder itself) you can just copy to the root directory and overwrite the corrupted one then reboot. It's the easiest way to fix it if you have a copy if the folder

You didn't try going back to stock yet? Tisk tisk. Do that. Check that your signal/IMEI works on a stock rom, then flash AOKP from that, then flash CM9 or MIUIv4 after that. AOKP has the updater.sh fix that allows you to flash directly from BML so do that first.
Lol I was going to but I was at work when it happened. Thats what i did when i got home. I knew I could go back to stock but I knew I had read a way to do it without going back so I really was more curious that I could not figure it out. Going back was really painless and fixed the issue.
I was more looking for the info posted above on how to do so manually. Thanks for the info... now I know for the future ha. I will give out thanks and add solved to thread title when I get to a computer. Thanks everyone

Hi I had the same issue before and what I did was manually push the efs folder from my sd and then powered off my device. Then I took the battery out and held the power bottom with battery out for 10 sec to drain remaining charge on the motherboard. Then popped the battery back in powered it up and walaaa my imei came back try it won't hurt :thumbup:

Not sure if the two are related, but I cannot get data over the network and my IMEI number is all zeros. This all seemed to happen after I tried to connect to AT&Ts network under "Mobile Networks." I have the 4g/3g icon at the top indicating I have data, but I cannot access any web pages and apps have no connection. I looked at my IMEI number and it is all zeros, something I haven't noticed before. I have no idea if this would cause the problem. I tried flashing back to stock, but still cannot access internet. I'm at a bit of a loss here. I tried looking up solutions but found nothing. I also seem to have lost my EFS backup, but I do have my original IMEI number written down. Is there a way to enter in a IMEI number manually?
Thanks for any help!
Yes they are related. Some have had luck reflashing the stock Rom. Which Rom have you tired and how (heimdall or Odin) (kc1 or kj6)?

Which would be the best for this situation?
P.S. I am able to send/receive texts and calls. Should I still be able to do that with a broken IMEI?
Text and calls, but no data is the no imei norm.
Not sure, are you using the one click from that thread or the one that is linked in last post? Jk6 is the most recent.
If I was in your shoes, and the one clicks didn't solve it. I would dig through the development thread, find Odin & whitehawks kc1 cleanup & try that. It would require removing the drivers that heimdall installed & reinstalling drivers through Samsung's kies. The Odin thread should explain that. But, that's just me.
You're not the first with this problem. Wish you luck.

The problem actually seems to be fixed. The IMEI number is still all 0s, but for some reason I am able to get data service. I'll take it. Thanks for your help!
And another thing that works for some people is switching between MTD and BML. Update to ICS, go back to GB.
But hope it keeps working for you!

Just throwing out an idea here.. would deleting the efs folder cause that folder to be rebuilt when the Rom is installed?
Sent from my SGH-T959V using xda app-developers app
the EFS partition gets rebuilt upon reboot if the partition is empty, which makes you wind up with the all 0 IMEI. The best bet is for you to restore a backup. All the ICS/JB roms we are using undergo an EFS backup when you upgrade to ICS/JB from GB as a precaution. As was stated earlier in the thread some users had problems going back and forth between BML and MTD ROMs.

Where does it make a backup to? I think I've had the all 0 problem for a while now, so it probably backed up a bad version anyhow. Regardless, my data is working even with the broken IMEI numbers, so all is well I suppose
The team acid updater.sh script backs it up to /sdcard/backup/efs.tar
See if anything is checked in "access points names " in mobile network setting , seems like it gests unchecked sometimes when i flash new ROM ,then i have to go to this setting to get network connection back on my phone .

I would reflash the Hyperdrive ROM with no theme. I've had that happen a few times when applying a theme to my ROM. if you flash the Hyperdrive ROM and it still doesn't work I'd flash a different ROM.
After flashing, (of course after full wipe) test calls and messages and contacts apps. Then if you flash a mod or theme after that. Try your phone,text and contacts again. If they do not work, then your theme has borked them.
I have tried re flashing the ROM and still nothing i wiped everything that needed to be wiped before flashing and still nothing. I didn't think a theme would make this happen. But I guess another ROM wouldn't hurt to see if it works then. Will post back after and I might need some help though if it does not work

Go to System Settings > About Phone > Status. Under IMEI there should be a 15 digit number. If it's missing or just says 0 then you lost your IMEI, which is basically your phone's network ID number. Also is your phone number correct as listed in that menu?

Assuming you didn't make a back up, you're going to have to restore it. Here's the link to a tutorial: http://droidmodderx.com/galaxys3/?page_id=79
It is pretty involved so make sure you read the instructions carefully. Are you familiar with ODIN, because the first thing you have to do is flash back to a stock rooted ROM. Use this thread for that: http://forum.xda-developers.com/showthread.php?t=1762204
If you don't feel comfortable doing all of it I would get somebody that does. You can easily hard brick your phone using ODIN. Also, ODIN will completely erase your internal memory. So I would make a backup of any photos/files you need before proceeding.

I do recommend once you get your phone straightened out go to the Synergy rom thread and find the zip to backup your imei and eri and put it away for safe keeping just in case.
