Hello,
New here and hoping someone can help me with my problem.
I've got an AT&T Captivate i897 that I put Jelly Bean on. The first time I did it, I didn't do the efs back up (the directions that I followed never mentioned it). This caused my phone to have a generic IMEI. After doing some digging, I found out that returning it to the stock GB 2.3.5 would put the correct IMEI back on the phone. I did this, and it did. I did a back up using EFS Pro 1.9.12. I then went back to Jelly Bean, hoping I could do a restore and all would be well. Unfortunately, this is where I am stuck.
EFS Pro 1.9.12 doesn't recognize the phone when I plug it in. I got the newer 2.0.26 version. This recognized the phone, but there was nothing for it to restore. I also tried using a root manager app, but there was no efs folder in there for me to put the back up in to.
If anyone could help, that would be a huuuuge help.
Thanks
If there was no efs folder, should just be able to make one and put the files inside. It's odd this only happens for some people, when I updated to 4.2.2 everything worked fine for me no efs backup etc.
But try putting the folder there anyway, reboot into recovery, fix perms, reboot. Might work (idk I've never had this problem, but putting the required files where they should be and letting the phone fix the permissions should help)
CM10 is the base of most custom ROMs. From stock (rooted and with CWM) flash CM10 and you'll see a backup of your original EFS folder on your internal SD. Check your IMEI in CM10, if good go ahead and flash your favorite JB ROM. Many custom JB ROM's require CM10 flash anyway (to create needed JB file system).

Tried this.. I think. When I plug the phone in and turn it on as mass storge, I get an F drive and a G drive. G seems to have all of the phone info on there, so I just create a folder G:/efs and unrar the backup into that?

I used CM10 to put JB on but I don't see a back up of my original EFS.

Which ever drive is the internal sd, if you can't tell put a folder on your EXTERNAL SD named blah and which ever drive doesn't have it is the external. You also fixed the permissions after placing the folder? If it isn't properly chmod'ed, the phone may not recognize it's existence or be able to access it. Once you put the folder on the internal sd, boot into recovery and fix permissions.
Tell me how it goes.

Ok, here is what I have...
G:/ was my internal sd. So I created G:/efs with my unrar'd back up put into that folder (I'd post a pic, but I'm still under the 10 post rule).
I then reboot the phone into recovery mode, went to advanced, and hit fix permissions. That did its thing, and then I rebooted the system. Checked the phone data and it still has the wrong IMEI.
I'm wondering if at this point I should just wipe it all, return to stock GB, do a back up again (any suggestions for something other than EFS-Pro for backup/restore?), and then put CWM+CM 4.2.2 back on and do a restore.
/efs is a folder in root, not in your storage. Need to use root explorer. Better go to stock to restore your IMEI.

Why not just put it in storage then just copy it to root with root explorer? Less work no need to reflash.
I know, but OP is not very confident what to do. Also, just restoring /efs very often won't restore phone's IMEI. The easiest and guaranteed method for him is back to stock.
Ok.. some success! I returned it to stock, did a back up, put the mod back on.. and now I've got the correct IMEI :good:
Now I am trying to take the AT&T sim card from the gophone that I bought so that I wasn't cut off from the world (the phone worked on my contract with my contract number) and put it into the Captivate, and I get Emergency Calls Only. I go into status and I get:
Network: Unknown
Service State: Out of Service
Mobile Network State: Disconnected
My phone number: Unknown
I'm guessing at this point that I just need a new sim card?
Also, thanks for all of the help so far.
Can you try this SIM on another AT&T phone?
What exactly JB ROM you flashed after stock ROM?

SIM works in another AT&T phone (Alcatel OT-510A to be exact).
I used the [NIGHTLY][ROM][4.2.2] CyanogenMod 10.1 for Samsung Captivate right from the Captivate Android Development thread.
Hmm... check what modem (baseband) version you have in Settings>About Phone. With CM10.1 it must be I9000UGKG3, I think.

Did you try this phone on stock ROM? Was it working with no issues? I'm out of ideas...
I'm not sure about the gophone sim, but glad to hear you got the other one working . Is your contract provider AT&T as well? If not probably would need to be unlocked for use with AT&T.
anyone else think this should be over in q/a forum

So, Please help what should I do to flash 4.2 version on my phone.
Edited: Thanks everyone, I made it work flashing different modem.

Check imei number. Version 4.1 & 4.2 have been corrupting imei number which causes no network

Hmm, for me, in ICSSGS 4.2, I do have phone signal and full service, however, when I pull down my Notification bar, it displays "No service.", which, fortunately, is a lie
Thanks for reply,
So is there any solution for this?
Thanks,

I'm a semi noob at the technical stuff, but I seem to remember that this issue can be solved by restoring the backup you have surely made of your EFS folder . This folder contains all the info about your carrier and such.
If you don't have a backup of your EFS folder, I cannot help you with my limited knowledge
Follow these at your own risk or search the forums for a more thorough explanation.
If you have made a backup use something like root explorer to look for the EFS folder in the backup & copy the two files nv_data.bin & nv_data.bin.md5. Now go to the EFS folder on the phone & paste over these to files replacing them with your backups. You can then delete nv.log, .nv_data.bak & nv_data.bak.md5. Or that is what I did and it worked.
If you did not make a backup then you would need to flash a stock rom which usually does the trick (all three files). As your IMEI appears to be fine in v3.1 I would make a backup of 3.1 & use those files. You could also copy the two files out of the efs folder and place them in your root directory then after installing 4.2 just replace the files with the ones you copied.

Many pepole who flashed RC4.1 experienced this problem, its due to the IMEI being changed to some default value. this can be fixed if you had backed up your efs folder, if not you have to reflash the official gingerbread then copy the efs folder using ROOT EXPLORER, this will fix the corrupted IMEI issue. This issue has been fixed in RC4.2 so after you get your IMEI fixed, flash RC4.2.

I seem to have the same problem, sometimes my phone reboots, and radio is gone. When I check, IMEI-N° isn't displayed, but after some reboots its back.
I did back up the EFS Folder, but how can I stop this from happening on a regular basis?

If you restored your EFS backup it should be ok...but since is happening many times...you can reflash a stock firmware and then flash again your current ROM.

By "backing up" you mean just copy/paste it to the respective folder?
Hello guys. This happened to me as well with onecosmic ICS RC4.2. Will be lashing back stock GB fw as I do not have an efs backup
Hi,
I have tried flashing 4.2 again and checked IEMI number, no change in IEMI number but no Network. It is saying Emergency Calls.

Hi ajay_lanki
the latest Team ICSSGS Build has a script to fix efs folder permission, which should solve the problem. Threat:

First: RC4.2 doesn't solve IMEI issue, i had it with 4.1, resotred efs, it worked, flashed 4.2, and issue again.
Second: The best way to restore /efs backup is going into /efs BACKUP (not original), multiselect every file, copy, and paste in ACTUAL /efs folder. Then reboot and that's it. If no /efs backup was ever made, the only way to solve imei loss is to go back to a stock rom (wich makes your imei come back), backup /efs from there and go ahead with ICSSGS again.

I've had the same issue. No matter how many times you re-flash the ROM and do FULL wipe, I wont change anything, because FULL wipe is not really "FULL", neither is Factory reset etc. For some reason it needs a "real-FULL-wipe" (Just something I made lol). Anyway you can do it following these steps:
1. Flash an NONE ICS based ROM, say JVU stock ROM .(Download it from Sammobile.com, go into download mode, and flash it using Odin 1.85 with 512 pit file)
(You are on a Stock JVU ROM now)
2. ROOT you JVU ROM. (Any method is fine but I prefer flashing Semphore kernel using Odin, just download the kernel from here, go into download mode, and put the kernel in PDA section and flash, no pit files needed for this).
(You are on a ROOTed Stock JVU ROM now)
3. Flash CM7 stock ROM. (Download CM7 stable version not a nightly version from their website, copy it to your INTERNAL SD Card, go into CWM and flash. If you had issues there just re-flash).
(You are on a stable version of CM7 that is already Pre-rooted)
4. Flash Onecosmic 4.2. (Download it, copy it to INTERNAL SD Card, go into CWM and flash, sometimes it gets stuck on a boot loop or on logo screen, go into CWM using the three buttons combo :Volume up button + Power + Home key. Once you're in CWM re-flash it again.
Do this and I will guarantee that it will solve ANY problem you or anyone else have with Onecosmic ICS 4.2.
Only problem you may encounter with the ROM is External SD card issues, which is caused by either the ROM itself or your own SD card.
A >> "thank you" would be nice . Have a good one.
Hey all,
I should mention first that I have a DesireHD and have never worked with a Sammy before today.
I went about looking to root and upgrade my friends SGS.
Followed this guide and all went swimmingly.
I got my head around what ODIN is and does, what files are what and how the procedures work for Samsung phones.
ICS booted and performed exceedingly well apart from the IMEI problems.
Now, over the past few hours Ive tried everything from as many guides I could find about backing up and restoring /efs. Nothing is working.
Ive tried all flavours of ICS ROMS but they all end up with a completely blank IMEI and unknown details in the phone status menu.
If I flash back to stock GB located in the kit from the guide all is well, phone works. ICS - no IMEI.
I took several backups of /efs using RootExplorer, Nitrality and taring through ADB. The restore just not work.
I also manually fixed permissions through RE and also using ADB shell.
The only common thing is that the IMEI through *#06# is completely blank, not 0's or 049 etc, just blank.
What would be my next step from here to get it working with ICS? Have I missed something? Is it just not going to work with this particular device?
I probably wont have the phone again till next week as I left it on rooted stock GB for now so have plenty of time to dig a little deeper into the issue ut would appreciate any help.
Thanks
Hello.Ive been on ics since the beggining and at first i had no problems at all.Last couple of weeks i started to have problems with phone signal and imei.Kinda lost baseband,huge battery drain,phone shutdowns and when restarted no imei or baseband unknown.Went back to Gingerbread and all was ok despite some battery usage but my phone has 2 years and i cant ask too much of my old battery.Was kinda disapointed but today i flashed Elite rom http://forum.xda-developers.com/showthread.php?t=1621976 and for my surprise the phone handle well without loosing imei or baseband.
So my advice is to get chainfires recovery for gingerbread and then flash Elite rom.It will give you a bootloop when restarting so you have to remove the battery,get to recovery and flash the rom again. Good luck
PS- Dont forget to wipe data,cache,dalvik and system before you flash

Coolio, theres a couple of apps in there that I hadnt come across so Ill defo give them a try at the weekend!
*sigh*
Still no luck with any of those apps.
Im gonna try everything from scratch tomorrow using the original CWM backup I did rather than from the rooted stock I flashed from the guide.
Am I missing something here? It seems that no matter what I try it will always give me a blank IMEI.
It wouldn't be by any chance be a I9000m or b? Probably a stupid question, but you never know.

I pretty sure its just a standard I9000, it was Vodafone UK branded before I got my grubby mits on it and I read a guide specifically for the M which lead me to believe it wasnt anything special. When on official GB its just says I9000 still?

I only really went of this from the guide:
THIS ROM AUTOMATICALLY SAVES YOUR IMEI FOR RESTORING IN CASE YOU LOSE IT!
after seeing that I took a manual backup of it the /efs as well and every time I flashed with ODIN using the GB flash kit from the guide I checked that the phone side was working then took another backup of it then.
I have several copies of it made from the GB kit, tared in adb and several apps used to back it up.
Your right with the CWM backup though, I read a post that said /efs is a separate partition that doesn't get backup up with CWM
My thinking at the minute is that either Ive missed something related to the branding side of it. I know one DHD I did needed things like a goldcard etc as it was Orange branded or the /efs backups I have have somehow been corrupted.
Now, Im still getting used to the versioning of Samsung FWs. Its currently on
Code:
GT_I9000_XWJW5_XDJV1_OXXJVC_Sbl
is this newer or older than
Code:
CWM ValuePack XXJVU Odex/Deodexed 2.3.6 [06-01-2012]
? It works fine on the first GB one.
Im thinking of flashing the second one today with odin then trying the stock AOKP rom as it doesnt install a kernal but flash Semaphore seperately. All the other ICS roms I tried flash a kernal before hand if that could make a difference?
Man, gotta say this /efs has proper knocked me over. Im not great with non-HTC products lol
Have you tried flashing semaphore.tar from the semaphore ics thread before anything else? It's kind of an all around wonder medicine for flashing issues.

Hi,
I bought a Galaxy S i9000 from someone for cheap because they said it didn't work. Anyways, after getting into ODIN on it and flashing a custom rom, I got it to boot. Problem now is, I think the IMEI number on the phone is screwed up (I get a message on phone startup) and can't connect it to the cell network with my SIM card.
Is there anyway to restore the IMEI number back into the phone, so that I can get it to register properly again? Also, then unlock it?
Thanks,

My IMEI got invalid too a few months ago when i flashed a custom CM10 JB Rom.
I got my IMEI back when I flashed back to GB via Odin.
Custom Rom developers advise flashing a CM9 ICS first before a Custom JB to avoid an invalid IMEI.
That's what i did, I got my IMEI back and currently using a custom JB Rom.
To unlock your phone, try to search in General Forum, there are some threads that discusses how to do it.
Yup, had the same thing with an upgrade. It's like the ROM upgrades but the IMEI bits don't.
You need to downgrade to get your IMEI back. Once you have it back DO A NANDROID!!
Then you can try to upgrade again.
It usually happens when you skip a version of android.. eg froyo to JB.
Just downgrade via Odin to stock firmware and upgrade each version in order.
Simple as that.
sent using my fat fingers from the robot eating the apple...
Well, restored to 2.3.6 and worked fine. I then installed CM 7.1 (Worked) then went to CM7.2 (Worked) and when I went to CM 9.0, it then stopped. No message about invalid IMEI or anything, just no bars.
Not sure, reverting back to CM7.2 for now.
You can try doing this process again but now backup your /efs library with Nitrality or some other /efs backup app.... make another copy of the backup in your pc and just restore it when needed...

Upgraded to CM 7.1, worked
Upgraded to CM7.2 Worked. Used Nitrality to backup /efs folder
Upgraded to CM 9.0, did not work. Restored /efs from backup. Did not work. Reboot, did not work.
So, for now it's back to CM7.2. I gave it to a friend to test out, if it works then he will be keeping it for a while and i'll try something else to upgrade it when he wants to. Thanks again for the help, seems it wants to be stubborn.
I was following this thread here: [IMPORTANT][GUIDE] What to do after you have bought your Galaxy S3 4G GT-I9305? and I got a bit lost in part 6.
I've done following:
1. Kies and drivers and on PC
2. IMEI/NV backed up on PC (USB modes set forth and back)
3.-4. Rooted and CWM recovery installed
5. Nandroid backup taken on external SD
6. Soo I got my backups secured in 2 locations..but what now?.. It says I have to go to part 2 and continue where I left off?
quote:
"Remember where you left off in 2nd step above? Well now you can go back and complete the partition backup of the efs folders. You should be left with 4 backup files for this final section of the backup process >>> http://splashurl.com/o7hwdsr"
But there is no mention of efs folders in part 2-link. I'm confused. I'm not native english speaker, so that messes up things sometimes.
BTW I did install Cerberus ROM at some point (Don't ask me why. Love the features, but don't know if there's any benefit it being flashed).
So I'm Rooted, CWMed and installed Cerberus ROM. I guess I have no stock ROM anymore?
And last: Is there a place you can search stock ROMs?
Edit #X: I found stock rom for what I have in phone. Galaxy S 3 LTE GT-I9305 I9305XXBMI3 Android 4.1.2

My first language is English and I didn't quite get it either. But following all the steps gave me nandroid backup and i think the qcn file is good enough for you to restore. seeing as you managed to flash a rom I guess you're all good. I was following the steps too and after I didn't get that part I just went ahead and flashed ROM, had no problems, maybe it was an edit error and guide maker forgot to add in something?
Difficult but reads as backup EFS to me and its no harm to have more than one backup .
So I'm Rooted, CWMed and installed Cerberus ROM. I guess I have no stock ROM anymore?
Correct.

Would have I been stock ROM without cerberus ROM flashed?
Hi everyone,this is my first post here on xda but i have been observing and following XDA forum for quite a while now,
Now recently I tried to install Origional CM10.2,
Steps i followed were
I had 2.3.4 ( i did installed CM9 almost an year back but then odin back to stock for reasons i dont remember now)
First i Flashed Speedmod kernel via odin 1.7, and then flashed glitch kernel zip using the recovery that came the speedmod kernel,
Wiped devlik cache and went on to install CM10.2,
Everything went fine till i noticed that i was not getting any reception and after googling a bit,identified the problem as efs folder corruption!
I immedietly flashed back to 2.3.4 using oddin and that solved the problem, and my fone was getting the signals on stock 2.3.4,
Following instructions from google, I used EFS recovery softwere to backup my EFS folder,
and then followed the same sequence to flash again to 10.2CM, but here come the tricky part, EFS pro didnt seem to work on CM10.2, i have everything installed perfectly, debugging mode is on, still cant get to restore the efs folder!
I even tried manually copying the backed up EFS folder and putting it in system folder using root explorer etc,but that didnt seem to work, I changed the permission to Read/write aswell, still it says operation failed!
EFS pro was my best hope but it just doesnt work, tried a newer verison of it(newer than the one that i used to backup the efc on GB),that opened but didnt have my device in supported list,and neither was showing any backup!!
This is what i have been doing for past two days
Now I am back to 2.3.4,and IMEI is working fine now.
and additionally just to check whether this happens only on cm10.2 or other versions as well, I flashed Cm10.1 aswell as cm9, same problem there aswell
(As far as i remember ,last year when i flashed CM9,it worked fine but was laggy so i flashed back,only thing i did differently was that i didnt install any kernel)
So any ideas how i should proceed now?
I would thankful if someone can help me ,
and sorry for the long story,i wanted to give as much precise info abt problem as possible!

Were you rooted when you tried to manually restore your efs folder? It should let you change it if you have the right permissions.
I would try to make a manual backup of your efs folder while you're on stock GB and try it again on the ROM you wanna use if you lose your IMEI again. Perhaps try another ROM as well, see if you get the same issue.
I have had problems with losing my imei after flashing to cm10 variants as well. In the steps that I took in this video I didn't lose it and I haven't had anybody else report that they have in the comments.

Arent Cyanogen Mods are already rooted?
I used the File explorer that was included in CM10'.2 and in settings i changed its permissions to ROOT ACCES.
Still i cant copy anything to EFS folder.
To be on the safe side,i tried Rooting Cm10..2 with Vroot,one click softwere and it showed that my phone had root Permissions!
Still I CANT WRITE ANYTHING WITHIN SYSTEM FOLDER,root explorer says that I dont have Root permissions, even after i rooted with Vroot!
I am confused

I would suggest trying with another file explorer. There are many on the Play Store (I personally like Root Explorer but there are free options).
