Hi,
I'm sure this has been covered many times but I'm finding little information that relates to the GT-N7100 or anything that I can actually get to work...
So, I'm new to flashing Android phones. This is my first Android device. I've messed around with ROMs on old Windows Mobile 6.1 and 6.5 devices before but not Android.
The problem I'm basically having is that my GT-N7100 no longer recognises quite a few system details, mainly the baseband version and the IMEI.
I'm not 100% sure where the problem first occured. What I did last night was:
Installed ODIN for Windows and flashed a root/recovery ROM to the device to root it.
Checked SuperSU was there, check. All good.
Tried to boot into CWM Recovery to flash a MIUI ROM. I got the Samsung Galaxy Note II GT-N7100 screen appear, followed by flickering like an out of tune TV.
After some Googling, found that I'd somehow got the wrong ROM for the GT-N7100, followed by a link to the correct one... so I downloaded that, flashed it, all good. I can now bootinto CWM Recovery.
Did a backup through CWM. Flashed the ROM, set it all up, then noticed I only had "Emergency Calls Only". Checked a few settings and everything looked OK. I did a bit of Googling and it pointed to checking the IMEI number.
Checked my IMEI and it came up as 004999010640000 which didn't look right to me. Tried pressing a few random buttons, nothing. Checked my box and that was definitely not right as my IMEI is 356000053********.
In a bit of confusion, went back into CWM Recovery and did a restore. This seemed to put the stock but rooted ROM back onto the device, clearing MIUI. Now I just have a circle with a line through it where the signal strength would normally be.
About Device says IMEI is "Unknown". Dialling *#06# brings up "null / null".
Now, I'm not sure where the problem occured, but I do remember seeing the circle with a line through it on the stock ROM before I flashed MIUI... so I've got a feeling it was the root/recovery that killed it.
I thought it did, but it turns out that CWM Recovery's backup does not backup the /efs folder, and even if it did, I've got a feeling it was fudged before I even got to that stage...
I have tried taking a copy of the existing /efs folder and pasting it onto my external SD card. I have then deleted the /efs folder, rebooted the device so that it regenerated the folder, deleted the nv_data.bin and nv_data.bin.md5, copied the .nv_data.bak and .nv_data.bak.md5 from the backed up copy and renamed them to nv_data.bin and nv_data.bin.md5 to no avail.
One guide suggested there may be a failed checksum error in the nv.log file, but there isn't a line that says anything about an md5 checkum error.
I tried one this morning that talked about using a hex editor to restore the information. I've done this again to no avail. I could see in the file that model number was correct when editing it, but no sign of an IMEI... but it was a large file...
I've tried a few other random bits and pieces that I can't remember, as to be honest, it was getting late and I was getting tired.
This is the information that my About Device screen shows:

The only thing I haven't really tried so far is just flashing a stock ROM to it. Not sure where to get this from to be honest either.
Any ideas what I can do? I have noticed while typing this that it doesn't seem to be registered a SIM card being inserted? It was last night... I did try booting with no SIM card and reinstalling the SIM, but it doesn't seem to pick it up now?
Any help would be great.

Little bit of an update. I have some progress.
I flashed back to the stock ROM and I now have a baseband version of N7100XXALIH, which is great. We're getting somewhere... but I still have no IMEI. This is the current report from my About Device screen:

Your imei is generic, if you have efs backup restore it
Otherwise flash stock rom +wipe if it doesn't solve then better send to service station.

Shame, I thought that might be the case.
I've just done a stock ROM flash and wipe which resolved the baseband issue... but it hasn't restored the IMEI. Unfortunately the backup I took didn't include the EFS when I thought it did so I have no backup to restore.
I'm just fiddling with a few things but not holding my hopes up. I might try a few things and if it doesn't work by the weekend, then I'll just unroot, try to clear the flash history and take it into CPW and say it's broken and I don't know why... see how it goes...
Not got much further with this to be honest. I've asked a friend who has the same device if he can send me a copy of his EFS folder that I could have a dig around with to see if I can find anything, but waiting on that at the moment... He sent me his nv_data.bin and nv_data.bin.md5, but when I put these in the EFS folder and rebooted (with no SIM for safety), it still pulls out the dummy IMEI number...
Someone has suggested to me to search around on here for the standard PIT file, to flash that and then flash a stock pre-rooted ROM which should sort it all out. I've not heard of this before, but from a quick search I've found that PIT is Partition Information Table... which suggests this is going to completely re-build the partition table and then flash a new device. Is this advisable, and do you think it could resolve my issue?
I've managed to install TriangleAway and reset the custom flash count to 0, so it no longer reports as custom firmware... I may just take it to CPW tomorrow and see what they say before I even think about messing with this PIT stuff anymore.
Unfortunately, EFS is a little more complicated than a folder with a few files, it's a dedicated partition which generally can't be restored without a backup.
Using somebody else's folder won't work, and actually using another imei is probably illegal since every phone is supposed to have one unique imei.
I've read that people some times miraculously get back their imei after flashing stock rom, but since you've tried it, I don't think there's realistically much to do besides sending to service.

I had faced the same issue and was able to get the IMEI back. Even I did not have the backup of the EFS folder. Go through the thread.
http://forum.xda-developers.com/showthread.php?t=2331833
Try to find a stock rom which has all three - CSC, Modem and PDA available. Install it with PIT from ODIN. (I installed 4.1.1) Once installation is complete, you should be able to see you IMEI number correctly. Root the device and take the back up of the EFS Folder and install any rom that you need. Hope this helps.
This is illogical
Flashing 3 files have no more role than flashing stock rom +wipe
On The contrary flashing 4.1.1 may brick your device.

I wasn't planning on actually using someone else's folder, but more using it to test if that was firstly 100% definitely my issue, and secondly to see if I could dig around to try and work out what might actually be wrong with the /efs directory. I have absolutely no intention of using someone else's IMEI, which is the reason why I took the SIM card out before booting it up with the new nv_data.bin.

Why would flashing 4.1.1 brick the device? I used a stock ROM to flash back to and according to About Device, I'm currently running 4.1.1?

Thank you so much for this suggestion! I tried it, but unfortunately Emergency Recovery wouldn't detect that my device needed it. I guess it technically didn't as the OS was working, just didn't have a working IMEI...
However, it did keep popping up telling me there was an update for the device, and everything had a different version number. PDA, PHONE and CSC all had completely different versions to what was flashed... so I thought, what harm can it do? Hit update, let it do it's thing and hey presto! I have a working device again! :good:
I'm doing my happy dance. Saved me a trip to CPW tomorrow! :fingers-crossed:

is it possible if you backup your efs folder and send it over to us to have a correct one to restore?
No.
It's different for each device. To flash others is illegal and all the devices have same imei will gets banned.
So never try to share same imei.

mine after upgrade to 4.3 same happened as DMG1 custom rom, imei getting 00499xxxx and cannot connect to network..
i'm really really frustated... does it seems that the modem chip is too old and cannot accept any new released modem ?
downgrade modem in 4.3 impossible, getting imei null.. flash kernel in 4.3 brings me boot loop and vibrate.. and no one cannot give me better solution..
i googling everywhere and found some method on how to repair imei using uart usb cable.. is it possible ?
Mobile network not available
Hi Dr.Ketan and everyone else on here.
I've been following/installing Roms and posts on XDA since the original HTC desire days before moving onto an S2 and then the Note 2, strangely enough is my first post. I have been following the progress of this rom since early October and finally decided to give it a try with the more matured version 3.
The Rom worked well and I can see this pretty much being ready as new daily Rom (ProBam is my current daily). There is one problem though that I have spent half the day trying to figure it out, I thought someone here might be able to give me advice. I did a backup in Philz then and full wipe before installing the Rom.
After the Rom loaded everything that I tried seemed to work quite well, apps in general were fluid and from what I could see things were as they should be. When trying to text or make calls I ran into “Mobile network not available” problems. When installing the rom I did select the MI6 modem. So far I have tried.
1. Checking the sim card (testing it in another phone)
2. Contacting my cellular provider (Cell C in South Africa) to make sure they didn’t block me for any reason (which they didn’t).
3. I went into network settings to manually select my network (it wont register to Cell C).
4. I tried restoring Probam again which works but now get “Mobile network not available" problems on that Rom, the same issue on todays nightly Cyanogen 10.2 which does indicate that this is a problem with other Roms now.
I did some hunting on Google and see that others have had similar problems with Samsing phones where their EFS folder gets corrupted and IMEI number becomes 0000. In my case it looks like my IMEI number is still there and when I checked my Philz backup I learnt today that a standard Philz backup doesn’t by default backup the EFS folder (just my luck). Short of downloading a 1 gig stock rom using crappy South Africa internet and flashing it with Odin might there maybe be a quicker way that I have overlooked?
Beyond this thanks for a really great Rom, I am curious what would cause this problem with the V3 Rom so that no one else is affected with this, I have flashed other Roms over the years and not had this one yet :>
Thanks!!

Sir, i flashed my nexus with AOSP rom(4.0.3),everything works well for several hours.but yesterday my phone shows error no service,i tries several sim card but facing same issue.so i tried imei no and guess what it shows nothing.... i checked baseband shows unknown. so i flashed stock rom via cwm (restore),but unfortunately facing same problem. so i flashed few baseband images also but not workrd either. plz help me how should i get my imei number back..... i have no backup file of my EFS folder.
First off, don't call me sir
I've been seeing alot of the same issue and no one seems to have a solid lead on the real problem.
And yes, it has happened to me.
My opinion is that flashing *some* roms is causing the bootloader to become corrupted...as this is exactly the issue I had experienced.
A fubar'd bootloader will screw everything up.
The solution for me was to odin back to stock.
Since you did not state if your gnex is gsm or cdma I am not going to attempt to post directions or even file names for you (you can easily search for odin and get them here in this forum). The directions are completely different depending on the gsm/cdma thing.
Be careful and make sure you have the right version of odin and the correct files to flash. It's actually pretty simple, but it's always the simple things that are easiest to get wrong.

What methods have you tried to return the device back to stock? You can try fastbooting back to stock which is fairly simple you would just need some knowledge of ADB and must have the Android SDK installed to do so. You can also use ODIN to do this or Heimdall depending on whether you are using Windows, Mac, or Linux. Feel free to PM if you would like some help with this!

I use fastboot, and don´t have luck. EFS partition contents exist, but i don´t have imei or baseband detected. I install google jellybean
Same happened to my GNex after flashing miui 2.11.16.
Common sense suggests that the rom, which doesn't include a radio, shouldn't be the reason for the unknown imei and unknown baseband fault.
This has also happened to others of whom most, including me, indicated flashing the updated recovery either twrp 2.3.2.1 or cwm 6.0.1.5/6 which were rolled out for android 4.2 compatibility.
I went back to stock 4.1.2 everything... GNex Tool and ODIN methods, but the problem remained: still UNKNOWN IMEI and UNKNOWN Baseband.
Common symptom to this fault is the phone/os thinks that Flight Mode is ON. Closer inspection in hidden menu phone information (*#*#4636#*#*) clearly shows the radio alternating On/Off continuously... all suggested tricks to set band to gsm manual or auto failed.
I have also tried the OMAP_Flash tool recently leaked from smsng team... it works as described (fix boot partition) but it wouldn't fix this problem.
Those suggesting it's a hardware fault are simply "just saying" but there's no actual prove or method to such a conclusion.
I'm leaning more to believe the cause to be a bug in the updated custom recoveries for android 4.2.
Hope this helps anyone trying to find a fix.... if you find a fix, please PM me
... and for now, i'm using my good old galaxy s i9000 <= will give it to anyone successfully helps us to fix the GNex

similar problem, but unlike dhuberto, not able to get imei back with any version of a stock image using any method.
My radio keeps going FLIGHT MODE on then off then on continuously... I have tried several apps to force gsm off (turn off radio) to no avail.
I personally still think it is not a hardware issue. Maybe it's me just hoping!
I have reasons to slightly believe that it was caused by a bad custom recovery code while doing fix permissions.
I am still researching and I will update once there's some news, good or bad.
My Radio stopped functioning earlier in the day IN THE MIDDLE of a phone call. I have not been able to get it to find a network provider since that time. My details are as follows:
Phone: MAGURO
ROM: Rasbeanjeally 4.1.2
Kernel: Trinity Stable 67
Provider: T-Mobile
Baseband: UGLH1
RIL: UGLH1
Location: Hawaii
I tried putting my Indonesian Telkomsel SIM into the phone to verify the problem was not a physical issue with the SIM and the phone could still not find a network. My Nokia phone works just fine with either SIM. I tried flashing another baseband to see if it had something to do with that but this did not help. I did update Busybox last night from the Play Store but i dont think that could have done anything as the phone was working this morning for a while? The Wifi is still working. Someone suggested that I reconfigure the APN which I did but that did not solve the problem.
After I reboot and go to About/Status, i see the following:
NETWORK: Unknown
MOBILE NETWORK: Unknown
SERVICE STATE: Out OF Service
MOBILE NETWORK STATE: Disconnected
Does anybody have any idea if there is some code i can run to talk to the radio to see if it is alive? Or does anyone have any other ideas what i can do to fix the situation?

The radio is gone. I just flashed the stock image after trying many other things and it is just not working no matter what I do. The phone recognizes different SIM chips but cannot get service no matter what I do. I have locked the phone and will send back to Samsung for repair.
Thanks all and especially to SIMMS22 for helping.

I do backup EFS with when i create a Nandroid with TWRP. SIMMS22 told me that if you can see your IMEI number, then the EFS partition is okay. My IMEI number is visible. Thank for the suggestion
Dear All,
I have a real noob. And have tried some of the roms you suggested like jedix and skynote and some other roms that can incorporate chinese display. I used some of your english roms and then afterwards would flash the root & unlock_language.tar on it. One day while I was on the JediX (non modem) rom and I believe i then flashed the root& unlock_language.tar afterwards. Was running ok I believe then suddenly no sim card. I have went back to original factory with no avail. Tried all 3 version of the original and to no avail. When I press *#0011#, it displays the following:
RRC: IDLE, Band1
MCC-MNC: 454-13
RX: 10614 RI:-61 CID: 11379
tx:9664, psc:42
Eclo:-2, RSCP: -63
SpeechVER: FR FR FR
L1: PCH_Sleep
Drx cycle: 64
SIB19 is received
therm: 0 LNA: 0
Service: Limited
Can you tell me what I did wrong cuz when I flash to original, it looks fine. Modem and Kernel looks normal but I cannot recognize the card. This is a tmobile SGH-889 UNLOCKED by T-mobile and was testing it in Hong Kong and suppose to give to a friend. Now I cannot do anything with it.
P.S. I did go to debug mode and tried to change some bands before but forgot what i changed but this appears to support only french or something? Very confused and seems like the incorrect band.... What can I do? I have no efs backup fyi.any
Please anyone, can you help me!!!!!
Thanks
Amy

Thanks for the update, I am beginning to suspect that this is the problem, cuz I see the IMEI however it is just wierd that one day it works and another day it doesn't. I think it is looking very much like a hardware problem now cuz besides the fact that I can grab all my IMEI but the odd thing is that my service INFO looks a little wierd. Who knows why.
As a side note you do not have to install a different rom to get Chinese languages. If your phone is rooted you can just go to "system/csc/" and delete the "language.xml" file then reboot. Your phone will have all languages like the international version.

At this point it would be best to restore phone back to factory stock.
http://forum.xda-developers.com/showthread.php?t=2102380
Use the above link to download a factory image. I recommend earlier versions as they are easier to root. Just use Odin with the factory image to go back to a factory state.
Then root again and follow my previous instructions to gain Chinese language.

Dear Zayydubb,
Thanks for letting me know, how long did it take for Samsung to get the note back over to you. :fingers-crossed::fingers-crossed:
Thanks
not registered on network. on my t889 too.
I flashed it to a ROM ,I'm a noob and did back up my efs.so now my phone don't read my sim card.please help.
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?

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?
NOTE: The information from me in this post below is wrong

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?

Even i had the same problem no network no imei nothing after downgrading so i just changed the modem and now everything is fine as it should be
Hi everyone,
6 days ago, I left my previous carrier (Bouygues Telecom) for a new one (SFR).
As I'm not used to buy my phones from a carrier, I did not think of simlockage... but I should have !
Because, last monday, when I installed my new SIM, I found out that the phone was locked.
I cannot join my previous carrier (access requires an eligible phone number, which I no longer have since I left them) and my new carrier cannot help me.
So, today, I tried to downgrade to an official 4.1.1, for trying the unlock via dial caller *#197328640# code method. But this failed. I installed GalaxSimlock app, and I found out that my IMEI wasn't the same: yesterday evening, it was like 354666... and now, it has become 004999...
I tried to restore my efs with TWRP recovery, but the IMEI remains the same... but I'm sure that IMEI was "good" when I backed it up (10 days ago). As long as I don't have any more solution, I would like to know those of you who faced the problem and, the solutions the found to fix the issue.
Thanx in advance.
If your imei is based on new rom, won't work old rom. At least you need newer baseband. Look my signature for multitool, that have option to update modem. (mg1)

My IMEI has changed too after a NAND restore. I had an efs backup to restore, but this made no difference. Now I can't register on any network.
I need help as well.
I used DrKetan's tool (which is excellent) but my phone now says I have no SIM card. I can't get the card out to clean it, etc, (It's a cut-down to mini-SIM original SIM card, usin a cutting tool from Amazon)
Now I've used the advanced multitool version. My IMEI is now restored and all is well in the world.

Good! Can we use multitool to r flash MG1 modem while on an old ROM? I wanna test this ROM with my original IMEI.

Yeah it's only way to restore imei on old rom. You can flash mg1 on old rom too and purpose to add it on multitool is only this.

Since this thread is about the same thing and since the OP has resolved his issue Ill mini-hijack it .. thanks
I have somehow killed my phone signal today while trying new roms.
I did a TWRP backup first of course including EFS.
At some point I could no longer get signal so I tried to restore my nandroid. The EFS fails to restore in TWRP.
I tried your tool to restore modem and while it completes it fails to restore my signal.
I wonder if you might have some other idea for me.
Thanks.

Now back to the hellybean nandroid which works fine apart from the efs restore which fails.
I completely wiped inbetween the TW and CM roms. I thought it was a good idea but I guess maybe not.
There is hardly anything in /efs just the imei folder which is empty and nv_data.bin and its .md5 as well as nv.log.
...
The twrp backup has the efs.ext4.win file at 5mb.
(i posted in the twrp thread too by the way, I hope thats ok)
