Sorry if this has been posted before...please be careful and don't blame me if you will brick your tab
http://forum.xda-developers.com/showpost.php?p=10605338&postcount=5
I haven't tried this method.
ok so we need to delete this "nv_data.bin.md5 and nv_data.bak.md5 "
do i need to delete that too : nv_data.bak
please let me know
This method just seem ridiculous to me. I just don't buy that you delete an important system file and pretend that all it does is sim unlock your tab. I would seriously think twice and make sure I have the /efs folder securely backed up in my PC b4 attempting to do that.
P_
p.s. nv.data.bak is a copy of nv.data.bin used by the system in case the original file gets corrupted. If you delete the .bin file there are good chances that it will be restored with the .bak one. But if you delete both ............. hmmm I am not quite sure in what kind of trouble you're putting yourself into. The .md5 files can be deleted with no problem, they will be regenerated on the next boot.

And yet 100's of people, using caution have successfully done this.
As always, do your research, ask questions, then go forward.
I apologies in advance if this is not the correct place to post this.
I recently purchased a rooted and unlocked SGS2. Coming from a Jailbroken iPhone4, this is my first Android. For more than a month everything worked great with my Fido sim. However, all of a sudden I lost data connectivity. After reading forums and researching on Google I reinstalled/flashed the firmware, modem and so on. But the problem still persists. In fact now my sim is not even recognised.
Did a clean wipe and re-rooted using Odin3 v1.85
PDA: CF-Root-SGS2_XX_OXA_KG6-v4.1-CWM4
Phone: MODEM_I9100XXKG6_REV_02_CL1044543.tar
Then performed a sim unlock using an app from Market.
Under 'About phone' the 'Baseband version' still say 'Unknown'
I don't know what else to do. Please help... Thank you

Sounds like your efs files got messed up, I don't think there is a way to fix it if you don't have a backup copy of your efs folder. Maybe Samsung can repair it for you.

I flashed generic samsung rom from here.
However, the phone is now stuck in a boot loop

Got it out of the loop by flashing these (below), but I am back to square one. I will try to find the EFS file from online...

Someone suggested "deleted the nv_data.bin and the nv_data.md5 in efs folder with Root Explorer, and renamed the .nv_data.bak into nv_data.bin, then restart."
Using Root Explorer I can access the efs folder. Where I can see all the files and my IMEI. But I cant make any changes as its read only. I have tried multiple code using terminal but I still can't access it.

Didn't work
I am in the same situation, is there any fix?
I fixed my problem by shutting down the phone, removing the sim card, booted, then the IMEI command returned a number.
I did a full backup of my efs folder. (nothing to do in solving the issue, but it was the time or never to do it).
Restarted, putting the sim back in, and voila.
iam in the same sitatuion .. :/
I've backuped my actual system /2.3.5 with CF Root Kernel 4.2 and restored the Original Firmware Backup i made at first day i've got the I9100
Then i try to copy out the /efs Folder, backup on my computer, restore the image from today and replace the /efs Folder from the stock rom... hope it works :/
// i think it works, but have to test - after restoring my backup i made 30 minutes before (with the baseband and imei problem (i backuped with this problem)) withhout chaning anything in the /efs folder it works, too.
I think some data after rebooting will be lost.. dont know.. have to wait and test :/
same problem here. tried to update to the new modem and this happened.

I wish i had known i needed to backup something before updating to the EG31 modem for the epic 4g touch.
Is there a fix to this? Cant use my phone until this is fixed...
download KTool or HC-kTool from new Android market, make sure your phone has root permissions or super user, you know after you root you get it anyway, it has efs file that should have a backup for your imie, also get Root explrer and Rom Manaer they have access to efs file, you should watch Mobiletech reviews on YouTube, he also provides his own tool that he says will fix your imie.

Try reflashing by stock firmware via Odin. In most cases you will get back imei. Do you have the efs backup with you?

Thanks for comment
No I do not have a copy of the file efs
You install programs but did not succeed
The /efs folder is a separate partition that holds the IMEI along with other things as device lock codes etc. This partition is not touched by firmware flashes, so reflashing a stock firmware will probably not help. If you messed up your /efs folder, you might have a serious problem if you don't have a backup.
My 2 cents...
Thank you for your answer
Yes, I did a survey of program file odin If I found a copy of this file is copied from another device will solve my problem and have the form tar
You can also try to rename files on your phone:
/efs/.nv_data.bak
to
/efs/nv_data.bin
I can't recall reading about copy /efs from another phone would help. But that could be just me not had time to read all posts in xda.

I hope you find the solution to your problem too
Thank you my friend and I also hope so and I know that each Mchklt solutions
Copying the /efs folder from another phone to your own will change your IMEI. Your phone and the original phone where the folder was copied from, will have the same IMEI then.
Please read the article in this link on the use of IMEI numbers before you might change it. I will definitely not give you a copy of my /efs folder...
My friend I know that it is wrong to take a copy of this file, but I now I can not take advantage of the telephone and the reason I am a victim of dealer deceiver has sold me a device and when you used to briefly stop working and when asked the dealer repair it to the Security Certificate refused to pick it up and when they put the machine when the agent of Samsung refused to receive the pretext that the device is not intended for the Arab States and the result was a project I did not find stolen
Is that anyone can upload media.apk? because I accidentally deleted this file
Thanks
Where is it in system? I can't find it, I'll upload it if you tell me where it is lol
Yes I think it's in system but I'm not sure. I deleted it with titanium backup so i really dont know where this file was
OK so I have searched the device, and it doesn't exist, maybe not in X-Note (which I am using) Or is under a different name, I searched for it on TB also and it cannot find it, so I'm a little puzzled.
Ok, don't worry and thanks for having sought
Hello Everyone.
So... I'll get right to the point here. My Galaxy S5 got stuck in factory mode. That day i was installing a bunch of ROMS. If you need a list of them, let me know.
I decided to go back to my old nandroid backup because I wanted to wait for a 4.4.4 version of the ROM i had found. However, I also got interested in installing a Custom Kernel, so I went ahead and installing Chronik Kernel cause I heard that it was really good. However, I forgot to wipe the cache and dalvik cache before installing the zip, so now I think it messed up my EFS partition, and am stuck in factory mode without WiFi and calling.
I have tried many methods involving the "FactoryApp" folder, but when I checked my phone to edit the text, the folder wasn't in the EFS folder. So I also knew that the Terminal Emulator option was out.
I even tried unrooting and re-installing the stock firmware and doing a factory reset, (I have a nandroid backup on computer) but even that didn't work. I can re-root if needed, but please someone help me, I really want to fix my phone soon. (Also I probably shouldn't have tried doing this on my vacation from home, oh well I am a really curious guy)
Help please!!
Someone please help me! I really don't know what to do! All that is in my EFS Folder is a bunch of APK files for apps i have installed and these files called: act_lock, react_lock and react.lock.bak. Someone please... I really want to get back on WiFi, also I am back from vacation, so I can use my Data plan to install things needed.
Is anyone going to help me?
OK. What is taking so long? I understand that lots of people have questions, but come on its been 1 week and no I be had helped me yet. Like I understand 3 to 4 days but a week? Please someone help me soon!

Typically it is in a file efs/FactoryApp/factorymode.
Can you show your efs folder structure?

It looks like you have an invalid efs folder.
Did you make the imei backup? If so just restore it.
If you don't have imei backup, try reflashing full stock firmware.

Yes, it is not too weird as Samsung now does not store the IMEI in EFS partition. It does store in another 2-3 partitions (these partitions are vary from model to model).
EFS partition does not contain the IMEI. It contain the S/N, WiFi and Bluetooth MAC addresses, etc...
Please do the following things:
1- Install Phone INFO ★Samsung★ app and look for the IMEI and S/N (in the DEVICE ID section), and compare them with the IMEI and S/N on the sticker behind the battery. Are they the same?
2- Create a file with a name 'factorymode' on the sdcard, open it, input 'ON' and then save it. Navigate to the efs folder, create the folder with a name 'FactoryApp' (case sensitive). Finally move the file 'factorymode' you have created above to that folder. Reboot the phone to see if the problem still persists?

Alright so the imei is the same but serial number isnt, however when I try to create folder it will say in efs partition: Operation failed:No Space Left On Device

Yes, as I have said, the efs folder does not contain the imei. However it does contain the S/N.
What did you mean by 'serial number isnt'? The S/N in Phone INFO app is still in valid format? Or it is zero or empty? Can you PM me that S/N (in Phone INFO app)?
Regarding creating folder, make sure your file explorer app has been grant root permission. And try to move/delete some APK files (in efs folder) to free space.
