[Q] Generic IMEI after OTA 4.3 upgrade - Galaxy Note II Q&A, Help & Troubleshooting

Hello to everyone, I was wondering if anyone can help with this. I have a Galaxy Note 2 branded by an Italian company (3hg Italia). It recently received its update to Android 4.3 (update N7100XXUEML2). It was the official update OTA, the phone is not rooted and it had the stock ROM on it. The update somehow messed up my IMEI making it appear as the generic 0049 forcing me on "Emergency calls only" mode. I already tried flashing the same ROM with Odin and repeating the update with KIES, but while the updates always results successful the IMEI remains 0049. I never made a backup of the EFS folder for this phone since I haven't rooted it or flashed any different ROM on it yet. There is any chance that the phone made an automatic backup? I live in the States right now and Samsung tells me I need to ship it back to Italy to have it fixed, but that costs a lot and would take forever, and I would much prefer try to solve the problem locally. Any suggestions would be greatly appreciated, if not for any fix that I can try myself, at least some place on the West Coast that can fix the problem!
Thank you!
Lorenzo

Oh I forgot to add that because of Hardware problems I recently sent my phone to Samsung and they replaced the motherboard, which fixed the problem I was having. I don't know if that could be related!

I'm afraid that fix works just if you have your actual IMEI, I instead have the generic IMEI that starts with 0049. But I will check it out! Thanks!

Then you should simply flash another modem from here : http://forum.xda-developers.com/showthread.php?t=2044937 ... flash a custom recovery first.

So I found someone nice enough to give me a hand with this situation, but still no luck yet! Here what they say:
At first glance, the EFS data on the phone was corrupt. I re-generated
that data and restored it to the phone without success.
The GSM radio itself is operational, and the firmware for it is
installed and functional. diagnostic data flows to the towers and back
to the phone but it's not reading the IMEI from the copy of
nv_data.bin contained within EFS. I've re-generated and installed
those files as well, again with no luck.
I rolled the device back to it's original factory firmware and radio
baseband, then ran through the update for the radio baseband, which
also regenerates the contents of EFS, and still no luck.
Given the situation, anyone have other suggestions?

[Help] Phone won't detect sim. Unknown Baseband and IMEI

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!

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.

[Q] Trouble with network connectivity probably caused by EFS???

Hello, this is really weird. In fact, when I insert the SIM to my Note 2 N7100 and turn it on, it allows me to make emergency call, but I cannot use it to make any others and it doesn't show the carrier name (it shows Emergency call only). And when I try to use it to make normal phone calls, it says that I am not registered to a mobile network. I try to factory reset my phone, but the problem remains. I then try to remove the SIM card, and it says that I need to insert a SIM card (that means that it is not a hardware problem since it recognizes the card). I then try to go to the mobile network setting to try to connect to the network manually, it connects me but it shows me a warning which says that the mobile network service is not available (and the Emergency call only label remains). However, I am sure that this is not the problem of the card neither since when I insert the card to my Moto MB860, I can make calls as usual. So, what is the problem ??? It seems to me that the problem happens spontaneously since it works perfectly until yesterday. And all other wireless function works fine including wifi , Bluetooth and GPS and the only thing goes wrong is 3g and 2g.
Additional information:
ROM: Omega v.16
Carrier: Fido Canada (as you can see)
Thanks.
What comes to my mind at first that something wrong with your sim card but if you insist that everything is ok with your card so I don't know what to suggest to you. Is it not related with your Omega ROM?

Yes, I did downgrade from v17 back to 16 since something went wrong with Poweramp but I forgot that if I selected for the efs backup or not since I (stupidly) didn't think that efs is important...:banghead:

Do some basic troubleshooting:
Does the IMEI number from dialling *#06# match the one on the sticker?
If the answer to this is yes: Then you should contact your carrier as it sounds like your IMEI might have been blacklisted (often if a phone is reported stolen)
If the answer is no: Then you need to fix your IMEI so it matches as it should. This would usually be done by restoring your EFS backup. I suggest restoring a totally stock Firmware if they don't match and you don't have an EFS backup. But you should have one somewhere, surely? Every tutorial out there tells you to back it up...
Good luck.

Do you mean the one in the About Device ==> Status? In fact, the IMEI from the dialing does match the one in About Device ==> Status. However, I don't get your instruction since if in the case where IMEI from the setting matches the one on the dialer means that my phone is reported to be stolen, then why I have to make the IMEI in the setting and the one shown in the dialer the same?

No, when I say "The one on the sticker" I, strangely enough, mean the one on the sticker.
Take off your battery and the phone will have a sticker/label with the IMEI on it. Verify that number matches.

Thanks for your clearification No, it wasn't.:good: Then, I need to flash a stock firmware via Odin, right? In addition, when they say stock firmware, they mean the one that is on sammobile.com, right? In other words, if I have a Hong Kong version of GT-N7100, the file from this link (http://www.sammobile.com/firmwares/3/?download=15126) would be the correct one, isn't?

That's correct, yes. It doesn't actually matter which N7100 image you flash, but if you have a Hong Kong version you might as well flash that image. Just make sure you don't have a N7105 (the LTE/Dual Carrier version) - flashing A N7105 to an N7100 (or the other way around) is a recipe for major disaster.
Flashing the image should fix the problem, but it also depends. If the EFS is really totally corrupt, it won't help, you need to have that EFS backup or take the phone to someone who can repair it for you. There are specialist tools to repair EFS, but they cost quite a bit of money. Most reliable phone unlocking places should have something that can help you.
Anyway, hopefully restoring to stock will fix the problem.
Good luck.

Thanks for information, but how do I know that if the EFS is "totally" corrupt, "partially" corrupt, or not corrupt at all? In fact, I never touch the EFS in the root. Also, as I am not quite sure that if I have any previous EFS(S) backup or not, so, if possible, where does the backup(s) most likely to be found?
If you haven't taken an EFS backup yourself, then you won't have any.
I don't know the difference between corruption levels either, all I know is I've read a number of forum posts where someone has reflashed stock and their EFS data (i.e. the right IMEI number) is back. So I'd consider that to be a partial corruption. Others have flashed back to stock and it's still a bogus IMEI
Basically, flash back to stock. If it doesn't work, you'll have to take it in for repair.
UPDATE: Please read on - this information is incorrect - it is possible to recover with the correct modem flashed.
Before doing the flash with Odin, do I have to perform a factory reset? Since all the app data and homescreen layout remains the same after the reboot and the IMEI is also the same as before. And is it normal that my device got unrooted after flashing the stock firmware?

It's normal your device got unrooted, yes. If your IMEI is still the same after ODIN and stock flash, then you have major issues (sorry!)
Doing a factory reset etc won't help. Your /efs partition is either gone or corrupt.
What IMEI does *#06# show?

Your baseband is probably corrupted. You may try reflashing a stock modem/baseband via recovery. I had a similar problem once, although I was on stock ROM, and re-flashing the modem zip worked.
I, however, tread very carefully here as I am aware the forum is wary about discussions relating to IMEI.

Everything looks OK as your baseband version would likely read 'unknown' if it's bad. You may, however, still try re-flashing the modem via the method posted in the attached thread ... Please proceed at your own peril as I offer no guarantee that this will work or will not result in damaged phones,
http://forum.xda-developers.com/showthread.php?t=1831898
Please note you will need custom recovery (e.g. CWM or TWRP). You will find instructions for installing custom recovery at the bottom of the thread. If this doesn't work, then you may try doing a hard wipe from recovery and reinstalling everything including system ROM, modem and kernel.
Hope it works out for you.
Simple fix is to reinject imei which located behind the battery.. But sometimes for some reason if you do this, you'll stuck with edge network, can be fix though but you gotta go back to stock in order to do so

you will have to google peoplearmy imei lte and find the tutorial on how to restore imei and get LTE back.
You will not be able to find the thread on XDA because XDA deleted it sometime ago. I was like you and lost my imei. Once I re-injected it using a tutorial on XDA, I was stuck on edge.

I can't find the link, can you PM me it?
I had that happen to me with a 0 on my phone and was able to get it back I had no backup either what I did is go on the NV Data restore or NV writer thread and downloaded the NV writer and put myself back on stock ...I went thru a few pages in the post and someone had a file where you could put your IMEI into that file maybe it was set up thru notepad but you could fill in the zeros with your IMEI and name it I think a txt.file after then open the NV writer and instead of backing it up cause you can't just restore that file where you fill in you're IMEI and it went right back into my phone. There also a video on that page how to do it. You just need basically that file to put your IMEI back in. I might still have it if not keep going thru the post took find it. There a picture of what it looks like to restore if you list it but every time I tried to open that link to restore it wouldn't let me. Hope it wasn't to confusing but it's basically a white box with a bunch of zeros and replace the zeros with your IMEI and save it as atxt. File I believe and just restore it as shown in the video for backing it up but just restore instead it does work cause I didn't have an IMEI on my phone it just had a zero

lets wait for others specially those who are expert in android for some advice. I'm just an ordinary security guard so i can't help you much with your problem. what i have suggested you from my previous post was the last thing I did when my phone finally worked. for 4 days i been searching for solution because i also have an IMEI problem. i flash back to official rom, flash patched modem, flash other roms to no avail until such time when my phone doesn't boot because of broken partition :laugh:. if you still have warranty restore it back. if you're already out of warranty and you have money, you can it send it to service center.
P.S.
you can also try this if you have courage. i was able to make some secret codes work but i have'nt tried if it works with engineering mode by modifying hiddenmenu in /efs/carrier/hiddenmenu. use efs explorer to open hiddenmenu and change it to ON.save it and restart your phone and see if engineering mode work. remember that you have to be in official firmware and also rooted to do this. if its not working then you'll just have to wait for a much better solutions from devs.
Same question

[Q] N7100 generic IMEI 0049 on 4.4.2

Please help me with my situations.
It is almost 1 week phone start making this problem. From beginning my phone getting boot loop. I have not root the phone. It is originally stock rom. I thought that the system get corrupted and then try to flash the phone with stock rom N7100XXUFNG4_N7100OLBFNG1_N7100DXUFND2_HOME.tar with odin.
This was my first time flashing this phone so I did not know anything about any EFS backup. After successfuly flashing the stock rom, at first I feel glad but suddenly I have got emergency call only. Then after what I have been searching and reading for almost a week, it was my IMEI 0049.
I have tried flash the stock rom again but the problem still remain. I have tried downgrade to 4.1.2 but the odin won't let me flash it. I have tried delete the EFS folder and paste the backup nv_data.bin but the IMEI 0049 still there. I don't have any service box so I can't repair my EFS from my computer. Is there any solutions I really really appreciate if and you guys can help with my problem. Thank you :good:
Did the imei in the phone match the imei on the label under the battery?

Of course not, usually IMEI starts with 3***.
I know your phone has a generic imei.
What I meant is this: did the imei in the phone matched the imei on label before the problem started.
The phone was new when you got it?

Ops sorry, yes it was matched and the phone working perfectly normal before it getting boot loop. Can my phone still can be save without sending to samsung?
You try using nvwriter to inject the imei.
Have you tried flashing the stock rom again? I assume nd2 is the latest rom for your phone.

I have not try the other version firmware yet, is it possible the wrong firmware corrupted my imei?
It is possible that the ROM flashed is too old.
I see stock ROMs here: http://www.sammobile.com/firmwares/database/GT-N7100/

Can you suggest me stock firmware? I am from Malaysia
I don't see firmware specifically for Malaysia. What is the original country or carrier for the phone? Where did you get the firmware that you flashed to the phone?

Well my country carrier starts with +6. I just ask my cousin to download that firmware for me since my house internet always disconnected I don't know why. I just ask him to download the latest firmware for my country.
That nvwriter guide is not for my phone. Is it work also with my phone?
Sorry, I'm not too familiar with nvwriter. I just know that some people have used it with Samsung phones.
The nv writer look promising, but it cannot read my phone cause when I select the rmnet/rndis/+dm+modem, it is only showing unknown device. Hmm my samsung usb driver already up to date.
