[Q] (i9000)Deleted efs folder without backup!! Possible to restore? - Galaxy S I9000 Q&A, Help & Troubleshooting

Unlike other cases posted previously...
All files in efs were deleted, including all hidden .bak files
Now, kies displayed my phone have a product code of XXXXXXXXX and a fake IMEI...
Is it possible to restore the nv_data.bin and other files??
Please help! Thanks....

I have the same problem, is there a solution for that?? Please answer!

Did you install sgs toolbox and used it's check product code function before you deleted your efs? If yes, there is still a chance. If no, there are currently no public fix available yet.

We are on the same boat, as what francis posted. No public fix yet but pretty sure there will be.. its just a matter of time.

the same thing happened to me yesterday when i flashed Cyanogenmod 7, got fake imei but everything worked just fine (call, data, market).
today i deleted everything from efs folder using Root Explorer then installed i9000XWJS5 then, surprise, i got my original imei back.
do not know how and do not know if it will work on you but it worth a try

The same thing happened to me.
If I dial *#06# no imei appears.
In order to use the phone everytime I boot up I have to give r/w permission to system folder. Otherwise it doesn't recognize the sim card.
It seems to me that that the device is not anymore able to recognize itself.
If I try to install CM or other AOSP rom I have status 7 error.
In Rom manager I have a window where I should select wich kind of device it is.
In fastweb installer there is a list of devices and I have to choose wich of them I am using.
I know that there is nothing to do with warranty. But is it possible to go back to a stage where it is possible to install AOSP rom?
Thanks

don't know it may work or not, but some custom roms make a backup of the efs folder on sdcard under /sdcard/backup/efs or /sdcard/backup/efs-XXX
(XXX= some numbers). you can try to restore it from there.
again don't know for sure...

Normallary Not

Thanks.
I have checked, but there is no backup.
I know the only one to blame it's me.
Do you think that there is anyway to make possible installing AOSP rom?

[Dev] Help needed, no apps in market??

I created a custom Rom, a really great mash up for people that like certain things from eugenes R2 final and Nero using KA6 while also implementing a very nice stock look (stock gingerbread messaging, dialer, contacts)... calling it Frankenstein. I of course will give credit and am not taking any credit away from these real great devs... this is just a mash-up.
This is where I need my [Help] while doing this, testing on my vibrant etc. I have managed to mess up my market.... my phone started off by not being able to connect (data) at all, and only having basic phone ability (mms, callling out).. I have fixed that, but no matter if I odin back to stock, do the eugene froyo odin/reformat back to jfd.. the market will not update. No apps really whatsoever... I get more apps when going to a rom like Nero V5 vs. stock JFD.. so this tells me that I am getting the market the way it was when they were implemented into the roms? but even with nero v5 im still missing a great deal such as titanium backup, file managers... even little things like doodle jump....
anyone that can provide detail that leads to a fix i will happily donate $15 via paypal, no big deal.
files must be missing, would love help.
Edit: have tried clearing data, resigning in.. all the little things... and as i said i have flashed back to jfd... now im on jfd with apps such as firefox test.. and a bunch of apps that were most likley the first apps ever put on market.. this puzzles me.
Thanks, Brandon
the only featured app right now is auto focus snake.. which looks like a android test app...
http://www.google.com/support/forum/p/Android+Market/thread?tid=55c997eccabf0a6a&hl=en&start=40
seems to be an issue with SGS devices and the market? WTF
Attached is a copy of the vending.apk I've been using in my kangs, and haven't had a problem with it. It shows all apps, on my phone its updated by now, but if it isn't when you push it, it should update properly given a little bit and a reboot. I would say if this doesn't fix your issue, it may be something else in your build. Just push the file to the system/app folder in your build, reboot and test it. Or, copy and replace the vending.apk in your working files, recompile and flash your rom, and test it. Good Luck.
so, select section you want, select free or latest or whatever, and you will see them.... or just search for the app you want
IMEI issue
I had the same issue all test apps in market and really no access.
I had to restore my backup and relock the phone.
Now all is working.
It is because certain apps don't recognize the Vibrant's build number. (T959KA6 is an example of a build number)

No I flashed back to stock tried Nero 5. Nothing helped had to restore nvdata. Imei was something like 004 phone was unlocked and tested on ATT. Look when you go into the market and it popup saying phone kay not support the market. Tried multiple google accounts its linked to your google account and your imei for supported apps on your type of phone.

You have to have a backup copy of your original.
If you do delete the files that start with nv -- in the /efs directory.
You probably can see your original IMEI if you open the file that is hidden in the directory /efs it is .imei -- That held the correct number for my IMEI. not sure if someone knows how to use that if you dont have an original backup of nvdata.bin.
I took nvdata.bin and put it in the /efs directory.
removed all files that start with nv in /efs example nv2data.bak
rebooted phone it built md5 from nvdata.bin.
factory reset and all apps back.
I also coudlnt get my pro license of titanuim backup to register with google checkout until this was completed.

IMEI
You're IMEI can easily be found by just taking out your battery and looking under it at the sticker with all the numbers and bar codes. It may just show IME and have either dashes or periods (you can ignore the punctuation). That is your original IMEI (this is nothing more than your serial number, make sure you know what it is because if you ever have a hardware issue and want to still utilize your warranty then they check by this number, and of course unroot the phone first so it won't be considered out of warranty)

HELP - CM10 upgrade and lost IMEI

Need some help here, hopefully without having to go back to JF6 (that is a little scary at this point). Was pretty happy with CM9 and updated through most nightlies. Just today I upgraded to CM10. All seemed to be working well except that I received a warning of invalid IMEI. I pushed through it and had the phone working on CM10 (with low memory /data isses - that could later be rectfied) then realized that the IMEI issue would mean AT&T would likely shut my phone down. The invalid IMEI is generic and has been flagged as invalid. I also ran into a few issues where I could not download from the Play Market App and think this was the reason.
I nandroid backed up CM10 and restored CM9 but still no dice. As I learned later it doesn't touch the efs folder which somehow the CM10 upgrade modified or had the effect to change it. Uuughh. many others were having the issue.
Anyway, I have verified that there are no /efs backups anywhere on my phone or SC or emmc cards. There are no backups within the efs folder. So, I am hosed. Any way to edit the nv_data.bin file a la this process for either CM9 or CM10?
http://forum.xda-developers.com/showthread.php?t=881162&highlight=restore+imei
This seems to be the only way I can see that would get me back with no IMEI EFS backup. But, going back to Android 2.1 Eclair or 2.3.5 Gingerbread would be a time killer and have to go through rerouting (?), upgrading, etc.
Any thoughts or direction?

All right it was a long painful night and day. Found and downloaded Heimdall One Click .jar with UCKK4 GB. Ran it and it restored the correct IMEI. It was unrooted and stock.
Then what was previously easy became an adventure to root and and load a kernel with CWM. I must have bricked the phone 10 times havimg to redo the Heimdall to Gingerbread 2.3.5 numerous times including reloading samsung pc drivers. Eventually with Odin, I found the right sequence using Corn Kernel for UCKK4 703 injected with CWM (not 705 or 706 versions which kept failing) which allowed me to get CWM loaded onto the phone.
I still could not restore my CM9 nandroid backups as the /data restore kept failing having to redo things from scratch. So, then I copied the latest CM9 nightly .zip onto the internal SD then loaded it from the Corn-CWM restore. CM9 booted and things were better but phone nad none of the settings and things still not right. Then rebooted into CWM recovery and restored the last CM9 nandroid backup. Now things worked and everything was back to normal with the correct IMEI.
Man that was a long stressing and scary day...
Made multiple copied of EFS for the future.
Will hold off on CM10 until the /efs issue is resolved as well as the memory management is better understood (while on CM10 I immediately ran into /data out of memory problems (I know I needed to move things to SD but never got around to it once the IMEI issue came up).
So, all is back to CM9 and finally working fine
odin to stock, then you will get imei back, backup efs folder, and flash back to cm10.
I have the same problem, but i'm om Rogers and 5 days now and no problems yet. I have a backup of my efs folder can I just copy paste?

Yes just make sure you set the correct permissions on the files. BTW You won't have a problem on Rogers. Canadian providers have all their black listed (lost/stolen) imei separated. They don't share it so a black listed imei on Rogers will work on Bell or Telus and vice versa. Only thing is that your phone can no longer be tracked by imei in case of emergency since its not the correct information but E911 will still locate you via GPS if you ever place a call.

It sounds like you have the backup that is sometimes made in the /sdcard (or /mnt/sdcard) folder, which is the internal storage you see when it's connected to your machine.
To see the /efs folder (assuming it exists), you would need to use either shell commands from inside ADB, or a root file explorer. If it's not there, you should just be able to dump the contents of that backup folder to a directory called /efs and go from there.

correct IMEI, but NO EFS folder --> no service

Hello guys, a friend of mine just gave me his phone because "it has got a problem" he said. He just flashed a ROM from CMW, but he noticed that there was no service. the problem is that, if I dial *#06# there is the CORRECT IMEI, but if I search for the EFS folder, there is no trace of it. how is this possible? the IMEI shown in the phone also corresponds to the IMEI wrote on the back of the phone... so it's clearly correct. how this could be possible? I tried adding manually the EFS folder using root explorer (and mounting it as R/W), but after the reboot the phone automatically delete the folder I created.. any idea? thank you!

Look in My Android Solutions
But First powerdown, pull out Battery, SIM CARD, and EXT.SD card, press power button for a minute, than powerup without SIM and Ext.SD Card, after flashing and reboot , insert them back
Tips before Flashing:-
Backup all your important files, contacts, SMS, game data, images etc to PC or Ext SD card. or make Nanadroid Backup If you have CWM
Backup your EFS Folder to PC or Ext SD card
Enable USB Debugging on Phone. Touch menu> Settings> Applications> Development>
Charge your battery to more than 50% before you attempt any sort of flashing.
Disable Samsung KIES when using Odin. Kill Kies.exe, KiesTrayAgent.exe, & KiesPDLR.exe using Task Manager on PC
Use only ROM and solution for your model and Wipe x3
nothing worked for me.. I tried to flash an earlier version of android, gingerbread, and the EFS folder was recreated but was incomplete. there were no "imei" folder into efs folder, and also there were no nv_core.back files, ecc... despite this, the IMEI number was shown correctly in the phone, but no signal/data... :S

no network service issue with jelly bean
I have a similar issue here.
First of all I flashed usin this guide:
thehelptimes.com/install-jelly-bean-on-galaxy-s-i9000-how-to-official-rom-android-4-1
provider is congstar (T-Mobile reseller)
*#06# gives me the correct IMEI
/efs folder exist
/efs/imei too
I tried killing the nv_data.bin in order to have the phone recreate it. That happened, now the phone asked for a pin at reboot but the pin doesn´t get
accepted. It also doesn´t get locked after 3 attempts. It just doesn´t get accepted.
Then I noticed that the rights of the nv_data.bin are different than the other files. I changed that but it got changed back after reboot and the pin still isn´t accepted.
I have no idea whats wrong. Next attempt back to gingerbread :-/

yep I tried restoring gingerbread, and, as I said, the phone created the efs folder, but it was incomplete... there were no IMEI folder, other folders were missing, and there were NO nv_data.bin files. I tried reflashing jelly bean and the efs folder was, again, completely missing...
Alright, I am gone back to XJVP but this wasn´t much help.
No signal either.
IMEI still shown by dialing *#06#
as of forum.xda-developers.com/showpost.php?p=26827676&postcount=4512
I need to get into root to kill the efs folder.
So I am back to XXJVU (gingerbread) now to get it rooted.
Before root there is still no network yet but I still can display the IMEI 3547.... (which is listed in the settings too).
Alright now I am going to root it. Hope this helps somehow.
I have the strong feeling that this phone ends up as a mp3/mp4 player
UPDATE....
- Alright, according to this I better not kill the efs by ODIN ? I didn´t yet. forum.xda-developers.com/showthread.php?t=1114958
- I checked the efs folder and noticed it is pretty much holding the same content as
in an efs offered for download "i9000 358001043596739 efs.rar" at 199.91.153.60/pa6q9c9bboog/eyyse638dh3kncn/i9000++358001043596739+efs.rar
So it looks pretty much like it should, I can see my perfect IMEI but it still doesn´t work. I am lost. No clue.
Back in my I9003 the SIM just works perfect so it is obviously not an issue of the SIM
UPDATE 2...
- flashed back to XXJP1 Froyo which was a bad idea now the IMEI is empty - F**K!
- going back to XXJVU now
UPDATE 3...
- Back to XXJVU still no signal however it detected at least T-Mobile at boot and gave me a radio box to select T-Mobile.
Sometimes the signal strength shows one bar (two bars when I am going to the window that points in direction of the sender)
though it should be fairly more here as other phones proof. No matter what that means anyway it says there is no service.
UPDATE 4...
- Compared the mobile settings with the i9003 and noticed that the i9003 shows EDGE, the i9000 GPRS
Alright, I got it back to GT_I9000_XXJQ3_XXJPY_DBTJS2 and made an official upgrade to the latest stock via KIES then. Nothing better.
I assume thise phone got a hardware defect then. Even though it doesn´t seem too logical

[Q] Problems Backing Up EFS info

Hi. I'm new to rooting and flashing ROM's. I have had a Samsung Captivate (Gingerbread) that I haven't been using for quite some time and I thought I might try to update it to KitKat. I have read that it would be important to back up the EFS file so that I can keep my IMEI info. I rooted my phone using the tutorial on these forums and tried to use EFS Pro, but was not able to get past "the device is not perm rooted". Various threads suggested changing adb status, but I could not find that information (though I was able to find the USB debugging selection). I know that the phone is rooted so I looked for an older copy of EFS Pro in case the newer versions had dropped support for the Captivate. I couldn't find one so I looked at other ways to back up the files, but most information was for other (newer) Samsung phones. I could not install Samsung Tools. I really don't want to proceed with installing KitKat before backing up the EFS information. How do I go about doing this? I have tried the search function on the forum for this device and couldn't find what I was looking for (or maybe I didn't understand the information). Any thoughts?
I hope flashing KitKat will be easier than this issue...
Thanks.

You could just manually backup your efs folder using a root explorer or through adb. Have that backup on your pc in case you lose your IMEI.
That being said, when it happens (which is fairly rare), a flash back to stock (KK4) usually fixes it and then you're fine to update/flash again.
Other EFS backup options would include:
1) EFS☆IMEI☆Backup by wanam >> his xda thread, his playstore listing.
2) [HOWTO]Comprehensive IMEI/EFS Backup lists two simple ways to permanently backup up IMEI on your phone. One is with adb, the other is with Terminal Emulator for those with rooted devices. The commands used are said to be based on "Samsung's built in backup." The thread is in the SGS3 forum, if nothing else is an excellent source of background information for backing up and restoring nvdata.
I tried to copy the efs folder using Root Browser because the adb method looked very involved. When I started Root Browser, it was able to see a Titanium backup that I had placed into the SD card even though I had formatted the SD card. I figured that the format didn't wipe the information so I proceeded to copy the efs folder over. However, after copying the folder, I stuck the card into my computer and did not see the folder and could not copy the folder over to my computer. Is it because the card is formatted differently than my computer or is it that the file is not compatible with Windows given that it is an Android folder?
Will copying the folder be enough for backing up? If it is this easy to restore the efs, why use EFS Pro? Is there something else with the folder that needs to be present in order to restore a phone that loses IMEI information?

If you have it on your SD card, it should be fine. The idea is to have it on something else than your device's internal memory in case something goes wrong and can't get it there.
As for efs pro, some devices can't manually backup like the Cappy or is not enough. But once again, it doesn't happen very often that you lose your IMEI.
Okay. That's great. I guess I can try my first ROM flashing to KitKat. Thanks.

S3 MINI i8190 IMEI NULL after cyanogenmod update

Hi guys,
Yesterday I updated my cyanogenmod 11 with newest version doing a wipe cache first. After rebooting my phone seems to have an issue: the IMEI is null and I can't call or receive calls.
So I decided to flash the stock rom with odin, I thought that this could help, but nothing to do, the IMEI is still null and I can't use the phone
The first time I installed cyanogen I made a backup (using TWRP function), looking for that backup files, I discovered a file called efs.ext4.win, but if I try to open it with an unrar program, I see these files inside:
\.files
\bluetooth
\FactoryApp
\imei
\RFHAL
\RFHAL.DEF
\wifi
GUARDFIL
gyro_cal_data
pre_recovery.log
I don't see any "nv_data.bin" file or something like that. Is that normal?
Anyway, I think that EFS folder is corrupt or missing, i don't know. Is there a way to solve this issue? Thank you.

Hi guys,
Yesterday I updated my cyanogenmod 11 with newest version doing a wipe cache first. After rebooting my phone seems to have an issue: the IMEI is null and I can't call or receive calls.
So I decided to flash the stock rom with odin, I thought that this could help, but nothing to do, the IMEI is still null and I can't use the phone
The first time I installed cyanogen I made a backup (using TWRP function), looking for that backup files, I discovered a file called efs.ext4.win, but if I try to open it with an unrar program, I see these files inside:
\.files
\bluetooth
\FactoryApp
\imei
\RFHAL
\RFHAL.DEF
\wifi
GUARDFIL
gyro_cal_data
pre_recovery.log

S3 mini has no nv_data.bin file in EFS folder. You made already a backup of your efs, try to restore it with TWRP to get your IMEI back

Thanks for replying.
I tried to restore EFS folder using TWRP and my backup, but nothing changed, I still don't have Imei and baseband.
Do you think that flashing a PIT file could help me?
Thank you so much.
