[Q] Corrupted EFS(IMEI, nv-data.bin etc...) Restore Efs folder, IMEI, nv_data.bin etc - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hey, I am now very much fed up with this Sprint Samsung Galaxy S4 Phone.
A few days ago I was trying to unlock my phone using simlock code *#0011#. That did NOT work! I tried other alternative methods to get even the sim card connect like connect to network. I used DFS CDMA tool to change my IMEI number but still nothing.
Then I found out about the nv_data.bin file. I rooted my phone, copied the "efs" folder using root browser not with command or anything I just copied it into my phone then to my computer. I then used EFS Pro tool //(I wasn't able to backup the efs folder before with this software)// to format the efs folder, then I copied the efs folder from the phone's other location and change the keystr to ON and factorymode to ON to get back my power menu and take out the yellow bar from comming. After that I checked that my baseband is saying unknown and IMEI is unknown. When I type *#06# to get the IMEI, it says "MEID" as title of the box and nothing else not even zeros. Also I do have only one file called maps_code.dat file in the /efs/imei folder. i mentioned this because I've read others' posts that they have maps_code.dat, keystr, and bt.txt files.
So Can anyone here PLEASE HELP ME!!! WITH THIS PROBLEM!!!
I have tried lots of different methods, none worked for me to restore the IMEI number I even tried to look into the nv_dat.bin fole using hex editor, but it says "ffff" and on the other side dots thats it. i looked at others, they had numbers and letters into them. However mine doesnt have any thing except "fff..." i can send all the pics you need to see.
THANKS!!!

Is there any Dongle/Box to repair the phone???

So first and foremost,im no expert with this,but here are my suggestions from what ive been reading.
The nv_data files are generated by the android os.
So this assumes you have no backup of the "/efs" folder.
Get ODIN,and download the stock MF9 tar file,i believe theres a listing for the files somewhere in the development thread.
Rooted or deodexed,you choose.
From what ive gathered,youre gunna need to reflash(with Odin) the stock firmware,and it "should" regenerate those files.
The Stock MF9 TAR file should be about 1.4 GB in size and ~2.x GB after extracted.if youre unfamiliar with how to use Odin,let me know ill walk you through it.
Before following through with all this,BE SURE to backup music,Pictures Etc,to your EXTERNAL SD card or better yet your PC.ODIN will reflash EVERYTHING.including your internal sd,so if you have anything there youre gunna want to back that up too.
In the meanwhile,
Read this.its for an S2,but the same concept applies.

the /efs folder on our Sprint GS4 has almost nothing to do with our actual EFS where the MEID/IMEI etc is stored. You should not have messed with these files.
I would first try to put the phone into download mode and flash a full stock tar. mdc, mdl, mf9.. doesnt matter. if you still have no signal after that... i would then try to do a ##786# > reset (you will need spc/msl).
keep us posted on your progress.

yep best to get a S4 tar file flash with Odin
easily found here

see if this works first.

[Q] /EFS folder empty?

I own a SIM locked Tab from Bell Canada and I'm working on unlock the SIM lock. I just used Z4root get the root privilege and was about to use RootExplorer to backup the /EFS folder to a microSD card. But the RootExplorer didn't show any file under the /EFS folder. I rebooted and checked again, still nothing in the folder.
ROM version: P1000XXJID
So what's going on here? Can anyone offer some suggestions?
Thanks in advance.
Was this an out of the box new tab or used? The empty efs folder is evidence of someone trying to avoid the t-mobile redirect when using the internet.
Go to settings> about device> phone etc and see what your serial number and IMEI number are.
Thanks for you response captain.
The tab is a sealed one (it's from authorized bell retailer), but the store claimed they got a batch of tabs with phone function (could be pre-flashed to some euro rom??). Just checked the SN and IMEI, they all match to the label on the back of tab.
The baseband version is P1000XXJID, don't know if this is the one for bell canada.
Well, don't worry, I deleted everything from that folder and I am in good shape. At least you have your serial number and IMEI.
Other than a blank efs folder, is everything else ok?
Captain, everything else works in the way as they should do. But I cannot unlock the SIM lock until I modify nv_data.bin file under the /EFS folder, can I?
So under this circumstances, how can I perform the SIM unlock?
Put in a sim from another carrier and see what happens - my guess is it's already unlocked. Anytime you use another sim you have to change the apn setting. That's in settings> wireless network> mobile network settings>access point name. If you don't know the particular details (approximately 14 entries), search xda for it, or google it. Usually I get lucky and the settings are already there when I go to change them.
Captain, I entered *#7465625# and it says Network Lock is "ON". I've searched everywhere....ahh, drives me crazy...

The proof of successful unlocking is putting in another brand sim and having the tab connect and run on the other company network, not what some setting says.
First of all, make sure that your device is rooted, after this install from the market: superuser, busybox & super manager.
Open super manager and give them root access in settings. This worked for me.

If your /efs folder "appear" to be empty it's because you do NOT have root privileges. The files are there you just can't see them.
You need to root your tab b4 anything else.

He already has root and installed Root Explorer.
I think you should put in another carrier's sim card and verify lock/unlock.
Cromed makes a good point. Is Superuser installed? And have you installed the latest busybox from the market?
I put in Rogers SIM card, the tab asked me for unlock code after bootup. I dismissed it and then the tab only allowed me dial emergency numbers.
I switched back to Bell SIM and using z4root to unroot and then rooted again. The root explorer still couldn't find any file under the efs folder.
P.S. I have installed both superuser and busybox from the market.
Captain, do you think it is possible that the retailer deleted the nv_data.bin file? It was quite suspicious that he mentioned of "official unlock service is available for $60". Assume they delete such file makes us no way to unlock the tab but pay for an "official service"...
And the tab comes with firmware with phone function which is supposed not available on Bell tab? Is P1000XXJID an euro firmware?
I'm sure that's what happened. I saw somewhere Roto sent someone a blank file for them to edit. Maybe search the forum. Have you flashed any rom yet? I deleted my efs folder contents and now files are in there.
Captain, I have NOT personally flashed any rom. Maybe i should re-flash the tab. Anyway, thanks for your help.
I just backed up my efs folder, then flashed Roto JMG, the full install, which wipes your sd card, and the efs folder had all the usual files and folders.
I would flash, because you don't need to be unlocked to do that.

The files only show up when you use a file manager with root access enabled. I had to download Super Manager (free) and give it root access in its settings and then I could see them.

unlock i5700?

Can I unlock it for free?
There is a method but it is not realy useable because you loose your imei.
1) Root your phone
2) Use a root explorer of your choice and go into the efs folder
3) Make a backup of your "nv_data" file by copying it to your sd card ("sdcar" folder)
4) Delete the "nv_data" file in you efs folder.
5) Reboot.
6) Now it is unlocked but your imei is 00000000...
PS: Your phone will still work without a problem even with a zero imei. You can always go back by copying the backup file into the efs folder but then the lock will be there again.
Tested with 2.1 os.

[HIGH PRIORITY announcement] anyone flashing roms

Mods please make this sticky.
Before anyone flashes any custom rom further, be sure to back up your
/efs folder somewhere on your PC.
The /efs folder is a hidden folder. You wont be able to see it using a usual file explorer e.g astro. You will need to be root to do so using root explorer for e.g.
This is something found sticky in the galaxy s forums and unfortunately for some of us it is coming too late.
The backup might come handy anytime if ever you mess up your own with custom rom flashing.
Thanks
Edit: just for you to understand the situation, by messing up i mean where product code and imei of the phone gets changed to a fail-safe one and even nandroid backups are of no help.
What exactly is in /efs that we need to back up?
I actually have already flashed one rom and after that I could not make or receive phone calls. I ended up calling Sprint and after about an hour of tinkering on their end they got it working. Would this be due to something missing in the /efs folder?
Everything concerning ur hardware info in short. Bluetooth, mac number, imei, ....
Many of us have got this tampeted with and unfortunately we had no clue it was something important( despite numerous threads in the i9000 forums warning users of this and nobody had backups) ,
there is no fix yet.
Check the nexussense forum for more details.
But do make a backup please.
After that whole incident I downloaded Samsung's Reflash tool and restored my phone back to stock.
Since then I have reflashed a custom kernel, but so far all is well. What exactly should be in the /efs folder as far as files.
My /efs folder has
Code:
imei>bt.txt
uart_path
bluetooth>bt_addr
nv.log
lost+found
Could you tell me if I am missing anything. I checked my MEID by typing *#06# and it matches what I have on the box.
EDIT: the bt.txt file int he imei folder does not have my MEID in it. Is it suppose to be in there?
I just copied and pasted a back up using root explorer to my sd card. I am on miui NS4G when doing this should I be on a stock rom?

Isnt this something that only gets messed with if you use someone elses Nandroid?
A custom rom doesnt normally mess with that folder, i thought...
Anyway, i have a Nandroid of my phone from before i flashed anything to it, so i assume im covered with that.
Can the OP please post a method to do the back up before making it a sticky tab?
Pointless to make it sticky and we still had to find the way to back up ourself. LOL

Agree even though it is pretty easy with Root Explorer. Just go to the root of the phone and find the folder called "efs". Long press the folder and choose copy. Go to the "sdcard" and paste it. I also suggest connecting your phone to your computer and save the "efs" folder to your computer somewhere you'll be able to find it.
An alternative to root explorer, you can use IO file manager (I think it works)/
From this thread ADB is also very easy.
Open a terminal emulator or ADB on your computer and type
su
busybox cp -a /efs /sdcard/
back up the file on your computer and you're done

Nandroid doesn't touch this folder, it seems. Best to make a backup on your own to be safe.

Look at this thread here. People are losing their IMEI number and is resulting in no service. If you back up the efs folder, it saves this information in case it happens to you.
I pulled it to my sdcard and computer. The imei folder is empty. I don't see a txt file and the bin files are all weird coding

Need Help - Baseband version: Unknown

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

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.

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 :/

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.

[Q] HELP! Samsung Galaxy S5 Stuck In Factory Mode!

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?

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?

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.
