unknown Baseband issue :( plz help..

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 #?

Ok i just checked my imei by *#06# and it shows nothing too !!! no numbers at all !! does it mean the it is efs corrupted partition ???

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.

[Q] Baseband Unknown, Signal Drops

Hi, i'm from Brazil and i have a Gnex from UK, and it's unlocked.
When i was at 4.0.2, everythings ok, but after the OTA update to 4.0.4, i'm having some problems if the data is turned on, and the option 'only 2g' is checked the signal is good, but if the data is turned on and i have 3G connection the phone lose signal, and baseband shows Unknown.
My Gnex is Yakju, and i have flashed the 4.1 (JRN84D) from here with baseband I9250XXLF1 and 3.0.31-ge8de0e2 kernel ( on the post shows that's a stock kernel ). And the problems still here.
More info about my Gnex on fastboot mode:
Product Name: Tuna
Variant: Maguro
HW Version: 9
BootLoader: PRIMEKK15
Baseband: I9250XXLF1
Sorry for my bad english, but i can't use 3G connection and i need to recive emails, etc
If anyone can help me, thanks! :laugh:

I'm not 100% sure but I think your kernel maybe be the Developer preview kernel, the official is 3.0.31-g6fb96c9, you could try flashing that? It's what I'm running with 4.1.1 and it works fine.

The 4.1.1 is available from OTA, but when i press to install the phone reboot then enter in CWM and shows a message that de update was found, try install but give me a erro message that failed, i'm a new user on android, my phone was an iPhone.

No, when de signal is dropped i had to take battery out from phone, wait 5 or more minutes than put it back! If i put it back before i have the baseband unknown message on Config > About Phone. And this happens only if i have 3G signal, i see many people saying about signal issues after OTA to 4.0.4 and if i still with "only 2g" selected i don't have signal drop or disable the data, then i don't have any problem

If it's the status 7 error it's because OTA's require stock everything I think, including recovery.

Not sure if it will fix the problem, I think it's in the kernel you have as that's where WIFI is managed, however you could try and if that doesn't work change the kernel.
Instructions on how to update to official 4.1 are here however if you want to then accept the OTA afterwards when following Method 1 do not delete/rename /system/etc/install-recovery.sh and CWM will be overwritten by stock and you should be able to accept OTA's.
Note: If you don't want to lose your data then you could try skipping the "Wipe data/factory reset" step but do that at your own risk, I skipped it and it works fine though.

a "different" kinda phone problem(?)
I looked through most all of these forums and couldnt find anyone with the problem im having. Not sure if it's me or what...
My problem is that when I flash some roms, my phone doesnt work. (yes im on sprint and only using toroplus). Well, yesterday, for most of the day, everything on my phone worked. When I got up this morning, It hadnt charged, and I lost my dialing again. Some ROMs I flash start off. When I go to settings> about phone> status under "Network" it says "unknown" and under "service state" It will say "no service" then checking on "Moblle Network State" It'll say "unknown"", sometimes my phone number shows up, sometimes it doesnt, Most times I cant make outgoing calls and when anyone calls me, it does a half ring and directs my callers straight to my voice mail. Is anyone having this problem too? And if so, how did you fix it? It frustrates the hell outta me and I think I should just go back to ICS although I dont want to. HELLP!!! :-/
Thanks,
Ridge

P.S. I forgot to mention that Im on a Sprint phone and that Im running Houng81's AOKP Aug1 version Baseband: fg01, the kernel that came with the ROM, Ive even replaced them a few times and nothing does any better. Forgot to add this to my prior text LOL sorry, that just gave me away as a n00b huh? HEHE

Doing the OTA might solve it since it will update (i think) your bootloader to lc03, you still on kk15. If it doesnt, use fastboot and update manually. To run an OTA with cwm installed, you need to download the update.zip from dev section for the OTA you want to run, but do it through cwm (like flashing a custom rom).

I read in another forum that the "factory" folder is the efs on the Gnex, and maybe my phone was with this folder corrupt, if i get a backup of another Gnex thats everything is working and restore to my Gnex will be resolve the problem?

Thanks for this post. I bought my mom a sprint gnex for mothers day, and sprint is pushing a 26mb ota. I put TWRP on her phone and rooted. Do I need the stock recovery to do the update, does the update break root?
Sorry, not familiar with Sammy or nexus devices, I've always used HTC. And the nexus forums are kinda hard to navigate because of the way it's split up.
Much thanks to anyone.

I had update manually to 4.1.1 factory image, the bootloader has been updated, and the problem still here, maybe this is an efs folder corrupted?

If you can access download mode, it's nothing serious.
Head into http://sammobile.com or http://samsung-updates.com and look for your phone's model name. They have firmware for pretty much any device so hopefully they have some for yours.

So the only thing that freaks me out is all these region codes... I dont see one for USA...Now what lol

I have the exact same phone and the exact same problem. Kies (via USB) recognizes there is a SPH-L520 connected but won't actually connect to it. I asked Samsung for the appropriate drivers (none are listed on the webpage for the device) but Samsung says there aren't any drivers for the SPH-L520. Kies does connect my SPH-L520 and my PC via WiFi, though. And, despite having enabled Developer Mode and USB Debugging, Kingo fails every time. Any ideas?

Try this: http://forum.xda-developers.com/showthread.php?t=2565758
It is also where Kingo originally got their method from, I wouldn't trust them too much if I were you. The best thing about the above method is, if it can't root the phone, it won't touch anything. If it can - it won't trigger the Knox. I tried on my JB 9190 and works. Unless you have a locked bootloader... that would complicate things.

hello guys is there a way to unlock samsung gs4 sprint to gsm been searching around cant find a good answer cos the phone seems to have a sim slot. also can it be flashed to cdma if the gsm potion wont work. thanks

If you're on NA7 as a few of us seem to be, you're screwed I believe unless someone comes up with a recovery we can flash through odin or kies. I would like to be wrong about that, but I haven't found otherwise.

The stinkers! I thought I read that Sprint was coming out with an upgrade to JB4.3 for us S4 Mini users, but it hasn't been pushed to my phone yet like the WiFi calling upgrade was. Think that might alleviate the Knox-blocks problem if/when it occurs?

Why would that alleviate it? Knox is here to stay. Very doubtful any update is going to remove it. Lately it's all about locking things down.

You might have done the wrong one like you said. Did you flash the latest firmware?

haha sure but i dont know which one is the right firmware, i bought the phone from a local store, without specific carrier for the phone.
also, i was able to find my IMEI written on the back cover of the phone.
is it possible to write the IMEI into the phone and just to make it work?
also, when im entering recovery mode to wipe the phone for new firmware installation, it says ""failed to find /misc partition"

you will get that error message as a ton of us do. should be an "e" in there somewhere.
I've heard of your situation when flashing older modem/bootloader in a custom rom.
You seem to know enough to grab odin and flash, that's a lot more than many so that's good. Not sure who sold you the phone, but if you want to rule out anything shady I suggest running the IMEI to check on the status.
What country are you in? Where did you download from? And did the phone bootloop soon after attempting to use it with a new SIM?
I looked on sammobile and the only information I could use shows multiple countries. My phone bootloops all the time but that's called learning.
Download the phone info app... heck you might as well go all out and put twrp on it and root/install custom rom. Go all in.... i'll be here waiting...

Honestly, though... grab the phone info app in the playstore and post the results.
If you THINK it may be stolen and got ripped off, don't put a SIM in it.
Not sure if it is true, but I think it can be rendered unusable if it is hot. But most likely it's just hurtin' from a sour flash. Phone info... (twrp is easy and a touch of magisk will give more info if you get stuck) but I am a rookie.
You in Israel? Can only be one firmware there... flash a Palestinian firmware. It won't... ya know... nevermind.
