So... I seem to be having the efs corruption issue with my co-worker's phone. I've been searching all over and have found how others have solved the problem, but it seems that our nv_data.bin is not located in our efs directory.
Does anyone have any idea where these files are? I need to check the last modified dates of their backup files to see if I can restore them >.<
Any help is greatly appreciated!!
Bump.. If anyone knows where these files are this could help us from running into the corrupt efs problem that many people have had. Usually backing up your efs prevents your phone from becoming unable to function as a phone.
I do remember reading something about our unlock code not being present in our nv_data.bin.. And when I check my efs folder in both my, as well as my co-worker's phone there is no nv_data.bin so maybe it has been relocated??
Anyone with knowledge on this subject.. your input would be greatly appreciated! I'm also gonna read over the unlock threads to see if there is any relevant info there.
I am having this problem now, I know you posted this over a month ago, but please tell me you know the location of the backup files or any other solution for this?'
Thank you,
[Q] T989 - Baseband and IMEI Unknown
I have searched and read many threads already. I understand the i9100 uses a file called nv_data.bin and requires its .bak file for a fix.
But, I dont think the t989 is the same because these files dont seem to exist, or at least not in the locations the threads for i9100 state. I am wondering if anyone has had this problem and/or how they fixed it. I know it was caused because of trying to unlock, but I'm looking for a solution.
Thanks!
just buy one of those $20 online unlock or go to your local phone kiosk to have it unlocked
any one with a machine to unlock Samsung phones can get this phone unlocked easily
there's no software unlock yet, as you have found on your searches
I have T-Mobile and don't really care for the unlock, it was a mistake. At this point, I just want to fix the unknown IMEI and unknown Baseband issue. Because of this problem my phone cannot get a signal... Will performing a machine unlock fix this problem?
Note: When I type in *#06# the response is not my IMEI number. It says "null"

You can try to find someone locally with a SPT Box2. This unit can flash, unlock & repair IMEI on SGH-T989(d). I was gonna pick one up, but they are like $250 yikes !!

What does the (d) stand for?
And, how can I make sure this never happens again in the future? I know there are backup options out there (CWM, Nandroid), but are there any that make a complete clone of the phone's image? In case I mess up the efs or IMEI files again I can restore and be ok.
Thanks!
T989D = Canadian release of T989
they are identical, the just use the D for Canadian

Would a Nandroid backup fix this in the future?
is hard to say, we have no idea where is the real IMEI information is being stored in the new models, but is no longer in the old EFS folder

I wonder if the new Galaxy Nexus has its IMEI files stored similarly. If so, we can join forces with that forum group.
If Android is not mounting your firmware properly in the system this will cause no baseband and no imei detected. i would try and flash the stock rom to make sure.

Did it twice, the stock rom, modem, and kernel.
The radio (modem firmware) might have got corrupted if somebody tried to flash international GS2 ROM or modem.
Try to flash only the Radio (KL1 is the latest for T-Mobile) via ODIN (use PDA slot).

Would the KL1 work any different than the older one? I tried ODINing the original one, and it didn't work and increased the count so I didn't try the KL1.
I just got my replacement phone yesterday for this same problem. Flashed the stock kernal, and also the modem just to be safe and nothing would fix it. From what I know its just a hardware issue, not software. I was chatting with samsung and t-mobile people about this trying all kinds of fixes to nothing left but hardware defect.
I lost my IMEI ... appears my efs backup doesn't have my original one either. I don't know how long I've been running on a generic IMEI but I would like to fix it.
There are some YouTube vids that explain how to fix it on SG Captivate and SG2 but none for our phones. It involves hex editing a string of characters. I have the stock NV with IMEI from an AT&T phone (thx bubor) but the hex string will be different for Rogers.

I'm wondering if anyone would be willing to share their efs backup (nv_data.bin) and IMEI with me. The only reason I would need the IMEI is to cross reference another thread I saw that shows a potential way to inject the stock IMEI into the efs. if not, thats ok I understand. Obviously sharing the IMEI with me involves a degree of trust.
In the end, once I get mine restored i will create a good how-to.
I've already tried flashing back to rogers stock w/ Odin, restoring from backup, removing the.bak files and letting the phone re-create them but all to no avail.
I appreciate any help with this and thanks in advance.

You are wrong, I sent roger version.
Litlekernel makes backup, have you checked ?
/storage/sdcard0/LiteKernel # ls
efsbackup.tar.gz efsdev-mmcblk0p1.img.gz
Thanks bubor.. i did check the backup and it has the generic imei in it too.. strange that the efs you sent me when i hex the nvdata it said it wass at&t.. when i have some time i will test with yours as shown in the video.. fingers crossed

Hi,
I have lost my IMEI as well. When i try to do a *#06# on the phone i get null/null in response. I have read everything that is available on this forum and others but have been unable to restore from the backup.tar.gz files i have. Could anyone kindly guide this noob here?
Thank You.
Yohan - were you able to restore the efs??
PS - I read that you have the nv_data.bin file for i927 at&t version. Could you kindly share it with me.
1. Turn phone off.
2. Remove back cover
3. Remove battery
4. Sticker with IMEI will be there.
[Just checked with my Rogers Glide]
might help with injecting it into another file or something.

dude, i have my imei however if you reviewed the video from the OP you'd see that the imei needs to be hexed back into the nvdata file - there's a specific order and since i only have one (my own imei .. from the label off the back of my phone and the box it came in ..) i can't differentiate if its correct and dont want to ruin things further.
Hi All,
I had purchased T-Mobile Samsung Galaxy S4 (SGH-M919) with Stock android 4.3 while I was in usa, and want to use it in my home country now as I have left usa. I couldn't found any unlock solution on internet for stock android 4.3, and T-Mobile would not give me the unlock code. I tried third party services to provide unlock code and it did not work either. So I went to a local shop, and he screwed everything up. When I went back to the local shop to receive my phone (hoping it might have been definitely unlocked by them), he told me that he tried to downgrade it to 4.2.2 but it did not work (only after reading through all the forums I realize there is no way to go back to stock 4.2.2 if you are on stock 4.3 because of knox / bootloader issues on 4.3, leads me to think the shopowner did not really do his research before touching my phone, and no, he did not do any EFS backup). In an attempt to unlock my phone, he also flashed Metro PCS stock ROM on my phone, not to mention, my IMEI number is also 'Unknown' now. I managed to get back on T-Mobile stock 4.3 ROM now but still IMEI is unknown. I also tried to go to nearest Samsung center and they said they would not touch international phone models. At this point I have no idea what to do. Any suggestions how to get back my IMEI and or at the least to get the phone working to my country's network?
Thanks.
Try flashing the mk2 modem using odin. That may work but not sure.

The local shop broke it. Tell them to pay for it.
Also, the only reason T Mobile won't give you an unlock code is if the phone isn't paid for in full. If the phone is paid for in full, they HAVE to give you the unlock code.
Are you sure you didn't buy the phone in the US, then leave the country without paying the bill so you could use the phone internationally without paying full price? If not, there is no reason T Mobile wouldn't give you the unlock code. So there's some missing information in this story.
Also, we do not discuss how to change IMEI's on XDA. The only thing permissable on XDA about flashing IMEI's is restoring YOUR OWN IMEI from a backup. That is done by restoring the EFS partition. But you didn't have a back up so you can't do that. That means anyway to fix your IMEI involves what is an illegal hack and that discussion is expressly not permitted on XDA. That information is used for illegal purposes and XDA is not going to be the place where it's shared for legal reasons.

Hi skipjacks, thanks for responding. Nothing is pending with t-mobile, I was on prepaid account. I bought the phone like 10 days before leaving usa (due to emergency). T-mobile says my number on this new device should have being working for at least 45 days or so with refill balance. My cycle ended after 15 days of purchase and I really didnt see any reason to refill it as I was no more in usa. And no, I dont want to CHANGE my IMEI, only want to restore my own IMEI only. I am not sure if my EFS partition is corrupted, because I rooted my phone tried to backup EFS folder now (I know its too late but still), deleted it and rebooted (as a few threads suggested it would regenerate nv data files), but neither did I see any nv files when I did a back up now, nor after I rebooted. When I rebooted, the EFS folder did regenerate but there were no nv files in there. Also, after deleting EFS and regeneration the serial number was corrupted, but when I restored my backup, the serial number showed up correctly again. Also my current backup contains the imei folder with mps.code_bat file. I noticed that even imei folder was not regenerated on deletion of EFS and reboot. I somehow have the feeling that this is still indicating that my original EFS folder is still present (though I may be wrong, because I dont know). But my concern is the nv data files, which I dont see anywhere. I did come across several threads about imei corruption and restoration, but the only one I didnt come across was T-mobile SGH-M919 with stock android 4.3. I am wondering if this has some different file storage structure for imei (which again I dont know). At this point I am concerned about getting back my imei, I can get the unlock code from some reputed paid service again. I understand that open discussion about imei involving anything CHANGING IMEI is not allowed here. If anyone could just help me out restoring my original imei, even by pm, I would really appreciate it. I just dont want to throw away the phone and lose my money because of the error done by repair shop.

First off....the enter key is your friend. Hit it every so often when typing giant blocks of text like that. :laugh:
Second, since your IMEI has been deleted, you now have to change it, even if you just want to change it back to what it was before. The process to fix it now is what can't be discussed here.
IF you had backed up your EFS partition, then it would be as simple as restoring it in recovery. That's all well and good. But your IMEI is now 0, so you have to change it to what it was.
But all that aside, you went to a store and they broke it. Take it back there and raise holy hell until they fix it for you or buy you a new one. I know consumer protections are stronger in some countries than others, but wherever you are, yelling and screaming is a universal language.

Can someone at least tell me what file in T-Mobile Galaxy S4 SGH-M919 Stock Android 4.3 contains imei number, so at least I know if I even have that file or not or whether it is missing? Thanks.

Whether your file is missing, modified, or corrupted, you need your /efs folder to restore it. You do not have have a nandroid backup or the /efs folder. I am sorry but the simplest we can put it without sounding harsh, you're screwed. You need to request the local shop give you a replacement phone or credit to get a new one.
Update: I went back to the shop and told them "You broke it, you fix it, I don't know how and I don't care, you gotta fix it". They managed to fix the imei number somehow. Regarding unlock, the shop ended buying the unlock code themselves. They mentioned that no one is able to unlock T-Mobile S4 with Stock 4.3 as of now without unlock code, unless they have some device like Z3x box. The phone is finally unlocked and working fine on my network. (YES, A HUGE HUGE RELIEF).
Everything is fine, except for 2 issues.
1. I want to backup my EFS folder so that I don't enter into trouble with IMEI again. I tried EFS Pro, but its not working. All I see is "'Initializing ADB server..." (the phone is rooted, usb debugging mode enabled, and supersu permission granted when prompted). I also tried to backup using Andromizer, but it says "Notification: File not found in /storage/emulated/0/Amdromizer/efs/efs.img". What is my best option as of now to backup and store my imei safely somewhere?
2. I am having issues with Wi-Fi. Before the shop flashed my phone, it was all good, but now it doesn't auto-connect to my home Wi-Fi anymore. Everytime I reboot or get out of range, I have to manually select my home network everytime and also enter the password everytime. Nothing has changed on my router. The other Samsung device that I have still auto-connects to my home Wi-Fi as usual. How can I fix this?
Thanks.

For the efs you can back it up using recovery. Just boot to recovery and its one of the options in the backup menu. The resulting file will be like a few KB. Its supposed to be small. Dont worry

As there's no solutions yet for the problems above hope you guys or some devs. can help/produce some solutions.. more specific situations:
1. you never backup the imei numbers
2. device totally bricked (fatal error/failed while flashing fastboot rom).
3. device fall into qhsusb_bulk, which no fastboot or recovery access..
4. bring it back to live with testpoint process(hardware) jtag likes on other devices.
5. its back to live with known baseband, esn but the 00/invalid imei.
what to achieves :
1. find ways to bring back its default imei numbers.
ive do some research and ive start a thread on miui forums too
you can see it here http://en.miui.com/forum.php?mod=viewthread&tid=166001&mobile=2
some people does have this problems too.
Anyone who wanna contributes some help some posible files needed to make it work:
1. A QCN backup from working/normal phones
2. NV backup files, again from normal phones with imei

I too lost my basesband, imei and wifi mac address.
But i got them back after restoring a few efs partitions that i downloaded from a blog I found.
It seems that I cannot post any links so i added some spaces in the url
Here is the url- www . amw-android.my . id/2015/05/fix-imei-baseband-xiaomi-redmi-1s.html?showComment=1445024870694#c3080464083769125141
did that procedures.. at the 1st try but seems its not working for me as my situation is Baseband is safe (not unknown) but the imei was 0..
CLOSED!!!! Since i succesfully write down the SIM1&2 IMEI, but still cannot get any signal, seems EFS partitions totally breaks
I had the same issue. Then I flashed with the fastbootrom country specific, i did India based using miphone flasher. In this you need to specifically select flash_all.bat, so that it erases the entire IMEI and updates with default from your phone. Once you do that, it restores the baseband MIUI rom. Then you can flash TWRP and then any custom rom. This worked very well for me and I could use my phone. Also the both the sim cards are restored.
Strange that, after flashing the Indian Fastboot ROM, i ended up with known Baseband, Wifi address. But IMEI still invalid or 0.
Any help please?
Thanks
Hi Guys !
Greetings to y'all!!!
I'm honored to be a part of this prestigious community at last and looking forward to give back, someday soon. My huge respect for all the contributing members, I have been using this forum to get help since 2016 and without even posting anything I've always managed to get helpful information to resolve every problem encountered till now ((rooting & flashing)).
:'D
So here goes my first thread:
A friend of mine recently tried flashing stock ROM on his SM-G988B/DS since his update firmware option wasn't working for some reason. Even though it was a success, in doing so he flashed wrong version of firmware and caused network failure, flight mode if tapped got stuck (greyed) (wrong modem was flashed). There was no backup and original firmware number wasn't mentioned so I tried flashing different versions of firmware (U1,U2,U3,U4 & U5) and finally got it working on flashing CP(modem file) of G988BXXU5BTJ3.
However, for some reason I still was unable to make a call, so I searched for it and found out that by dialing *#0011# my IMEI status is NG which is bad , even though my IMEI number is still intact as found on the back of the phone. I researched a bit further and found out that this has something to do with the EFS file and whilst going through comments in another forum I found someone else had the same issue and got resolved by deleting nv_data.bin file and its backup and IMEI folder in EFS file after rooting and reflashing stock ROM. I tried the same but found that nv_data.bin was missing in EFS folder, so I backed up EFS file and deleted just the IMEI folder in it and reflashed stock ROM, have tried flashing different CP versions aswell still no success .
I've seen some videos of Chimera IMEI rewriting and certificate patching and Z3X tool on youtube but in their case IMEI is missing and I don't want to go for those solutions for the instance. I'm wanting to learn from all this exercise and want to know whether what is what and how to resolve this manually (maybe by writing some hex code or script etc) if possible.
Summarized:
Phone: SM-G988B/DS
ROM: Stock (G988BXXU5BTJ3) (rooted)
Status: SIM Card Registration failure ( IMEI status NG)
IMEI : Intact (As on the back of the phone)
EFS file ( nv_data.bin and .bak missing)
Previous Status: SIM Card was working fine before flashing ROM
Your valuable suggestions in this regard shall be highly appreciated.

First, do a TWRP backup, all partitions including efs & modem.
Open the root explorer app, open the efs folder, delete the files named nv_data.bin
, nv_data.bin.md5 & the folder called imei. Then open twrp, wipe all partitions. Flash the latest firmware with Odin.

Hi Guys !
Greetings to y'all!!!
I'm honored to be a part of this prestigious community at last and looking forward to give back, someday soon. My huge respect for all the contributing members, I have been using this forum to get help since 2016 and without even posting anything I've always managed to get helpful information to resolve every problem encountered till now ((rooting & flashing)).
:'D
So here goes my first thread:
A friend of mine recently tried flashing stock ROM on his SM-G988B/DS since his update firmware option wasn't working for some reason. Even though it was a success, in doing so he flashed wrong version of firmware and caused network failure, flight mode if tapped got stuck (greyed) (wrong modem was flashed). There was no backup and original firmware number wasn't mentioned so I tried flashing different versions of firmware (U1,U2,U3,U4 & U5) and finally got it working on flashing CP(modem file) of G988BXXU5BTJ3.
However, for some reason I still was unable to make a call, so I searched for it and found out that by dialing *#0011# my IMEI status is NG which is bad , even though my IMEI number is still intact as found on the back of the phone. I researched a bit further and found out that this has something to do with the EFS file and whilst going through comments in another forum I found someone else had the same issue and got resolved by deleting nv_data.bin file and its backup and IMEI folder in EFS file after rooting and reflashing stock ROM. I tried the same but found that nv_data.bin was missing in EFS folder, so I backed up EFS file and deleted just the IMEI folder in it and reflashed stock ROM, have tried flashing different CP versions aswell still no success .
I've seen some videos of Chimera IMEI rewriting and certificate patching and Z3X tool on youtube but in their case IMEI is missing and I don't want to go for those solutions for the instance. I'm wanting to learn from all this exercise and want to know whether what is what and how to resolve this manually (maybe by writing some hex code or script etc) if possible.
Summarized:
Phone: SM-G988B/DS
ROM: Stock (G988BXXU5BTJ3) (rooted)
Status: SIM Card Registration failure ( IMEI status NG)
IMEI : Intact (As on the back of the phone)
EFS file ( nv_data.bin and .bak missing)
Previous Status: SIM Card was working fine before flashing ROM
Your valuable suggestions in this regard shall be
