Well, from the day one i bought my nexus i had the " unknown baseband " in the About screen of my GSM unlocked NEXUS ! ... I dunno how but i left my phone with sim card inserted for some hours and suddenly i noticed that i have a signal and i checked to see the baseband is identified as xxkk6. Now i downloaded the Factory image from google and i flashed it using the Nexus Toolbox and now i dont have any baseband again.
Tried to flash the baseband only again with no luck, It only shows in the fastboot mode but when the phone is in android mode or ( normal mod ) it shows as unknown!
Tried to flash the UGLA4 baseband and the problem persists!
What should i do now ???
Try to flash back to google stock rom via Galaxy Nexus Toolkit from mskip :
http://forum.xda-developers.com/showthread.php?t=1392310
Download google stock image here :
http://code.google.com/android/nexus/images.html
Then, using GNex Toolkit again to root, unlock bootloader, etc and flash any baseband from this thread below to test :
http://forum.xda-developers.com/showthread.php?t=1405345
i already did that and still not working!
I tried flashing the stock rom over and over , ulnocked , rooted and flashed the baseband file alone and nothing works!
i tried to flash ugla4 and xxkk6 basebands but both didn't work and i only can see them in the fastboot mode info
If you can't seem to get it to work, try returning it to the vendor.
As last resort you can try with ODIN it might work...

I can't return it as i bought it with no warranty from an online store in my country ...
Ok, how can i use odin to restore it ! i mean i need a pit file and the other files right? where can i get them from ?
another thing, do i find the files if i extracted the factory image
thank you!
Install cwm and flash the baseband from there. Should work. Search cwm touch in the forum.

That doesn't mean it has no warranty contact your country Samsung warranty service and explain the situation it must have warranty!
I tried flashing it with CWM and nothing seems to work !
Am i the only one who has this problem ? is it hardware related or what because as i said it was working before and i was able to make and receive calls and data ..
It wasn't workning when i first turned on the phone when i bought it but i was playing around with the setting and apps and i remember having an OTA update from 4.0.1 to 4.0.2 and after 2 or 3 hours it started to work ! just like that !
btw i flashed the old 4.0.1 (ITL41F) factory image and i updated OTA now to 4.0.2 ICL53F but still unknown baseband
are you using a custom rom on the phone?
if you are...you may have installed a rom for the LTE/CDMA phone and not for your GSM phone..
that is why my baseband said UNKNOWN......I had a LTE and I install a GSM rom by mistake...
try installing a custom GSM rom

here there is a similar thread...somene talk about a corrupted efs partition (try to search something about it), someone just flashed a new radio and solved it
did you also tried to power off the phone and pull the battery for a while? it is a sort of software reset..may work sometimes..
Sounds like your EFS may be corrupted.
There is an app for the I9100 that can repair corrupted EFS's, and it can be done via adb as well, but I'm not sure about the applicability towards the GNex.
Just for reference, I am in no way suggesting you do this, but perhaps someone else can chime in: http://forum.xda-developers.com/showpost.php?p=17587351&postcount=1

I may have jumped the gun a bit, with the i9100 an unknown baseband typically meant a corrupted efs. Do you still have signal and an imei #?

Likely, but again I haven't messed around with the EFS on the GNex yet. Hopefully someone with more knowledge can chime in and get you sorted out.

Btw i didn't back up anything and i don't know how to fix the EFS thing but i know how to use odin and adb a little bit
i have this issue suddenly with the radio of 4.0.2 and fixed it by flashing 4.0.1 radio.
never mind .. i got another Gnex and everything is fine now !!! u can't fix it but in samsung service centers
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.
g'luck

There's no 4.0.3 images for the gnex, at least official ones.

I had this issue as well. I couldn't get the gnex (GSM) to show up in Odin to even start flashing anything so the only thing I could do was send it in to Samsung.

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
Do you have signal? are you in the same rituation described in this post? http://forum.xda-developers.com/showthread.php?t=1797931

I really don't know if it's just a solvable software problem or it's an hardware one!

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.
I've spent nearly two weeks trying to figure out what happened to my phone and how to restore it. After OTA 4.1.1 (I forced this clearing gsf), in a weak coverage area toggled airplane mode. It wouldn't come back out.
Fastboot flash, CWM, TWRP, dd command, Odin, re-partitioning, nand erase all - any attempt to flash radio-cdma.img hangs or fails.
I can confirm that many of the dire warnings about hard-bricking your device... Well, let's just say that with everything that I've tried, even the bolder attempts in the end, did not brick my device. Odin would always get me back.
Baseband Unknown
IMEI Unknown
My Phone Number Unknown
Everything!!! UNKNOWN
I found some threads on here mentioning CDMA tools and I've downloaded and attempted a couple, it seems that my pc has to have all the supporting programs to make a connection to my phone. The problem is these posts are not specific to my device but the S3 and it seems like a whole lot of trouble when there isn't a 'known' path and specific files for my VZW GNX.
I have also ran emmc check several times and memory checks out good. Sim card has also been replaced.
So I sit here today with 4.1.1 installed (less the radio-cdma.img). I can Odin the older stock images found here on XDA by deleting the radio-cdma.img within. Then use fastboot to flash the 4.1.1 images individually to have a Wi-Fi only device.
I'm willing to try anything. Any takers?
Your meid is smoked. You will need to completely reprogram phone. A restore won't do it Cuz its the serial of the device from factory. You can't fix unless you have msl
*Shaolin Shadowboxing*
Thank you for the reply!
Could you point me in the right direction? Is this done using CDMA tools? I've seen places that mention it can be done via the handset dialpad (other devices). I've found threads that give suggestions on how to contact your carrier to get them to give you the msl... and I've also seen posts that state that Verizon's MSL is almost always 000000. My brain is turning to mush! :cyclops:
Thanks again

Verizon msl is usually 000000 you will need either the box device came in or the numbers under battery. The sticky part us going to be the MSID number you'll have to put in. If you have the ORIGINAL nandroid you made immediately after you unlocked bootloader, that one might work but no guarantees. The dialer code is *#*#msl#*#* with msl being the 000000. I believe that's it...could be *#*#spc#*#* with spc being spc and then have to enter msl. The MSID is mobile subsidy identification. Sometimes its NAM. Your MIN would be your phone number..mobile identification number.
If you get into the MEID it will have a couple numbers to enter. The numbers you will need will be your ESN hex and dec. I have all the dialer codes and can pm you a link if you like. Once you finish with the MEID repair that's where the NAM MIN thing will be needed. Unfortunately, the NAM/MSID isn't the same as your number and won't accept all 0's but once the meid is back you might be able to restore but am not positive on that. Can call Verizon and have them refresh phone I believe once meid is restored.
*Step Away From The Toolkit And NoROM Gets Hurt*
I tried the dialer code *#*#000000#*#*
The phone did nothing although as soon as I completed it went the field cleared. I'm on my own. Verizon told me a week ago they were sending me a refurb. Called yesterday and there was no record of another phone being sent out. Rep told me my Sim card was not activated in their system and a ticket was opened to have it unlocked on their network. It should be fixed on their end today. However, I still think I'm going to have to get radio-cdma flashed on my phone. Using getprop (from app market) it appears at some point I may have flashed GSM radios. I say this because there are GSM listings from the getprop output.
Any suggestions?

I'd probably return everything to stock first. ##XXXXXXX# and *#*#XXXXXX#*#* codes depend a device's factory ROM.
I'm not convinced it's your MEID though. That alone wouldn't stick your phone without signal and you'd still be able to flash a radio. I'd also be careful not to mess with IMEIs or MEIDs unless you're absolutely certain that's the problem. If you're hell bent on it or you're doing it for fun, not caring of you wreck it, look up MEID repair and read up before messing around.
It wouldn't hurt to try and install a new radio via CDMAWS or a similar program. Just don't change anything you're not familiar with. You can really screw things up with programs like that if you mess around.

I'm pretty sure that my problem is due to flashing GSM on my device. I have not had any luck finding out how to go back. I'll check out CDMAWS... first time hearing about it.

Does he have the samsung drivers installed? If so does his computer recognize his phone when plugged in either adb or fastboot? Cause if he does then you can easily go back to stock 4.0.4 IMM76k using my link in above post
MEID definitely smoked. *#06# yields nothing. I have tried flashing back to stock IMM76K but cannot get past radio-cdma flash... it hangs. If I remove the radio-cdma image it stock flashes no problem... but I still don't have MEID when doing that. I believe I flashed GSM ROM or radios at some point. I say this because when in terminal emulator and type getprop, the output has several gsm entries. Verizon is sending me another SIM card. But before I put it in I believe I need to have the GSM stuff off the phone. I'm not quite sure how to do that.
My screen is cracked, Verizon and Samsung can do nothing for me. I'm on my own on this. I have two rumor touch (sprint) that work fine. I also have HTC EVO 4g (Sprint)... been looking at activating on Verizon, but have had no luck getting CDMA tools to recognize phones... even after wiping drivers and re-installing multiple times.
I'm stuck using a very basic Samsung Knack flip at the moment... Sucks big time. Cash is short so I'm trying to make do with what I have.
Still needing help guys and gals!
And thank you all so much for your ideas and suggestions! I have learned a lot!

I just started having this issue the other day as well (baseband/IMEI, etc all unknown). Phone was just sitting on my desk when I noticed it didn't have service. After being unable to flash the cdma radio, I am trying to get the phone back to stock. However, I am unable to flash the stock image because there is a version check for the cdma radio. Is there a way to flash the stock image without the cdma radio check?

Any luck with yours. I just started having the same problem. My phone freezes and I have no service. I am trying to return to stock using this GUIDE but my phone freezes whenever I try to Flash the CDMA Radio. If I skip that step it doesn't install the stock version and I'm stuck in Paranoid 3.2 and unable to return to the store in the current condition due to warranty issues. If I can make it stock I will go get a new one.

Just wanted to let others know that I was on a JRO03O rom, decided to return to stock 4.1.1 and must have screwed up something because after getting back up and running I had the same issues as OP. No baseband, IMEI, *#06# was blank, etc. I was about to embark down the path JediNinjafication linked to, but it looked extremely intimidating. Jaymazz's link to Vabeachfc3s reset tool worked like a champ, put me back at at 4.0.4 and all the radio stuff started working right away! Phone updated itself to 4.1.1 shortly thereafter, and it's still going strong.
Hi Everyone,
I have a rooted Galaxy Nexus, Verizon version, and just flashed this ROM:
http://forum.xda-developers.com/showthread.php?t=1737849
Unfortunately I did not do a backup of my IMEI folder, which I realize now was a huge mistake. If I do a "*#06#" then the screen comes up with a blank IMEI. Baseband version is unknown, network unknown, phone number unknown.
I've been searching around all afternoon and tried a few things, namely:
Installing the JDQ39 radio, and
Manually adding my APN (Verizon)
The radio didn't seem to make any difference, and I was unable to get my Verizon APN to show up in my list of "Access Point Names." After I save the info and name it still doesn't appear on the list, even after a reboot.
So, I'm not sure if I'm even on the right track, the most promising post I've found is here:
http://forum.xda-developers.com/showthread.php?p=17587351
But in that post, the OP says I must have the "shipped original EFS folder on my phone," and I don't really know where to even look for that. If anyone has any insight I would be greatly appreciative. Thanks in advance for the help.

But in that post, the OP says I must have the "shipped original EFS folder on my phone," and I don't really know where to even look for that. If anyone has any insight I would be greatly appreciative. Thanks in advance for the help.

no /efs aka /factory backup, you're pretty much without options.
I have also same problem
IN flash the android 4.2.2 rom on my samsung nexus device (JDQ39)
And I don't have backup of efs folder
Now in my mobile no imei
I flashed radio.img for xda thread but nothing happen
IF want ti recover my imei
Plz help me recover it
Sent from my HTC X920e using xda app-developers app
Phone: Samsung Galaxy Nexus GT-i9250TSGGen
I had a stock android version, that I never rooted or flashed. Suddenly the SIM stopped working, I figured out that there is no IMEI number and the baseband is unknown.
I flashed to a custom ROM, and tried to do few things using the Galaxy Nexus Toolkit:
1) custom ROM android 4.1
2) Flashed a custom radio
3) made a copy of the /efs folder, deleted the original and replaced it after restart.
The Samsung service center said the entire board has to be changed, with an estimated cost of $140 USD.
Can someone help me with my options? Is it definitely a hardware problem? is there anyway to know for sure?

If you have a nandroid back up, try and restore with it. This could solve ur problem.

Thanks, but I hadn't created a back up before. Is there a way to use a back up from a different phone? where would l find more information?

I had an old nandroid back up and I used the method in this post to fix my IMEI problem: forum.xda-developers.com/showpost.php?p=47048361&postcount=9
And when you said you took a back up of the /EFS folder, you meant pulled the .bin and .md5 files from the /factory or the /radio folders OR did you use something like kTool? Because, as people have pointed out in other threads there is no /EFS folder for the Galaxy Nexus. The IMEI information is stored in the Radio and Factory Folders. For more information on how IMEI works on the GNEx, refer to this post: http://forum.xda-developers.com/showpost.php?p=47045295&postcount=6
But you are saying the baseband is also unknown. A radio flash should have fixed it. Try restoring Stock ICS using Odin. i hear this fixes some problems like this. U can use thus guide forum.xda-developers.com/showthread.php?t=2065470
If Odin is a little complicated, try the Nexus Root Tool kit. U gotta experiment to find the right problem and them fix it. No other go. I doubt that replacing the board will solve it as it looks like a software issue, unless you fried your radios.

Thanks again. Yes, the /efs folder is not where it was supposed to be. I did find the correct location and moved it. I will try using your ideas. Just one more question:
Since I had not done anything that would wipe out my IMEI number (neither software hacking nor physical damage). I wonder why this problem suddenly occurred. Just to eliminate a possibility, how can I know for sure that I have not "fried the radios"?
Appreciate your help. If I know that it is a software problem, I can continue to play with the Nexus toolkit and try different solutions.

I'm not sure how to check if your radio is fried. Basically, it means something's wrong with your hardware, where you experience occasional or complete signal loss. But in your case, you lost your IMEI. So, back up your nv_data files, flash using NRT or ODIN and see what happens.
NRT will push the stock radio while doing the "Flash Stock + Unroot" Option. So, you'll get the stock baseband as well. This should fix it. If your IMEI still doesn't work, try restoring the nv_data.bin and md5 files you backed up as mentioned in the link I posted.
Let me know how it works out. :good:
Always make a backup of /EFS (Support in both PhilZ_CWM & TWRP )for safety, though the IMEI would be only wiped by CWM wipe /factory option......happened to me a few days back, luckily i got my /efs restored & flashing stock doesn't bring any IMEI back since it's actually phone specific plus comes with a proper MD5 !!
the above method should work and here more info on the EFS
