Baseband question - Samsung Galaxy Nexus

Hey guys I have a question about baseband compatibility
My GNex is completely stock 4.1.1 and is rooted.
I was on bigxies ROM running uglc1 and I seemed to have better reception with it.
Thing is, ever since I went back to stock, I've tried flashing the same radio over xxlf1 and I can't get any service. I am experiencing the same issues once again such as random signal loss and no service. I ran GetRil and everything is good there.
So is it that you just cant run a different baseband on a factory installed rom or am I doing something wrong?
Any ideas are greatly appreciated.

Not all radio versions are compatible with every version of Android. This sounds like you have a GSM version of the GNex as I myself have a the CDMA/LTE version but in some cases when new version of Android come out or leak or what have you it's best to keep current the radio versions with the OS.... If that helps or makes sense at all. I do know that on the CDMA/LTE JellyBean updates I'm still using the radio versions from 4.0.4 with it and it's perfectly fine. Have you always had the loss in signal or is this only of recent with testing different radios?

I got it to work. Apparently some thunderstorms knocked out at&t service last night and I was flashing radios during it so when I got done, I couldn't pull any service down. While I'm still without signal, I know its not a radio issue now. Thanks for the response

Radio problem? OTA problem?

I no longer run AOKP and a custom kernel, I went back to my "stock" 4.0.4 yakju build I flashed after finding out I had a yakjuxw.
Now, after following efrant's guide, I run the XXLA4 baseband/radio, and apparently the "XX" signifies it's good for Europe? I think I read that somewhere.
I also heard that there was a newer OTA available other than IMM76D, but I haven't found anyone yet. Did this "yakju" conversion really work? I'm wondering because I didn't find any OTA after flashing 4.0.2 yakju, so I manually updated to 4.0.4 through their official OTA I download manually from here.
Is there any way to check if the OTA thing REALLY works? My phone does report itself as a yakju, according to the GN official update app. I do not want to flash a custom ROM again for a while as I feel I never gave stock a chance and most ROMs are nightlies, which I don't like.
I've googled for a long time now and haven't come up with anything useful, other than "erasing data" for the Google Services Framework which didn't help.
I just found out the crappy reception was because of a carrier-related issue which, hopefully, would be resolved by the 20th.
IMM76D (build) and XXLA2 (radio) are the latest yakju 4.0.4 OTA #'s.

They are the ones I'm using. I heard that flashing some other radio got rid of the problem, but I don't wanna mess with radios like that on a three days old phone.

Different people have different experiences with radios based on their location and provider. If you don't wanna mess with it, then don't.
Specifically what radio problem are you having? There are reports of dropped signals, but I have yet to experience them.

No signal when phone enters sleep mode.
EDIT: It seems to have been resolved by raising the minimum lock from 350 to 700 Mhz.

Looking for info on flashing I747M (CANADIAN) to AT&T modems

tried it once without any luck. going back to stock telus ROM at the moment.
has anybody had any success flashing an AT&T modem onto an i747M?
i am using the telus variant
edit: reason i wanted to do this was b/c i was getting some consistent signal drops. after having to go stock telus -> CM10 nightly (8/20), i'll see if i'm still getting any drops. that was the reason i wanted to use an AT&T modem, but if the issue doesn't come back i'll withdraw my inquiry

I'm using 8/18 and I'm not having too many issues. CM has been my daily driver for 2 weeks. I'm on telus as well. I haven't tested LTE, but once I'm back at school I'll figure it out and make sure everythings working smoothly.

CM10 8/20 nightly works great, i'm not getting any of those signal drops i had from before. maybe the phone just needed a full wipe. anyway, i'm not too curious about flashing an AT&T modem anymore. it would be nice to have a choice of modems, but that's definitely the lowest on my list now that there aren't any drops
I am using the LLE8 stock Bell modem even though my firmware is the latest ATT LH1: I did attempt to flash the full LH1 leak including the modem, but lost my IMEI in the process. Seems the modems do not play nice across different carriers, even when the phone is an I747 -- the developers then removed the modem out of the firmware package and the LH1 release installed without any issues. So my experience is that the ROMs are quite compatible, ATT to Canadian users, the source code for the kernel is standard across all SG3 phones according to the developers and the experience of people using kernels irrespective of carrier designation BUT the modem (baseband) does not appear to be cross-carrier friendly. So until a fix is developed and/or one of the Canadian carriers updates their firmware, we are stuck with LLE8 or its equivalent..

yep. i came to the exact same conclusion. i'm not too worried about it; phone takes a few seconds to hop on to LTE where i am, but no big deal

Cellular signal Issue with GSM GNEX after flashing to 4.2.2

I have a International GSM GNEX from Negri which was recently flashed to stock 4.2.2 via fastboot. I have flashed every north american radio and most European radios and have not been able to get more than about -100 dbm signal strength since the flash. My IMEI is not corrupted and other than the signal disparity, everything is functioning fine. My carrier is AT&T and my current baseband is UGLL1. I can access all the information on my SIM card so I'm not sure if that is the issue. Returning to prior versions all the way back to 4.0.4 does not resolve the issue. Does anyone have any ideas?
Thanks.
I've got the same.. Ive flashed everything roms, radios, kernels and the GSM radio is still crazy unstable.
Update if you have a break through.

[Q] Radio flashes to fix signal loss not working

Hi, I'm not sure if theres thread on this but my signal is lost. two weeks ago i wake up one morning to find my service isnt working,the sim does work on my two old phones so it's not a sim issue. I then found my baseband is unknown. So I searched and found some fixes which are too flash the radio with a new radio through either clockwork mode or nexus toolkit. I've tried 5 different radios all being diffrent updates of the galaxy nexus radio. I was runnung 4.2.1(which i hated) but now I got android revolution HD 2.1.2 and ak kernel and downgraded to 4.0.2(yes the phone is unlocked and rooted). I was wondering can anyone tell me whats wrong before I factory lock it and unroot and send it in for warranty repair. Btw phone was with Rogers/Fido carrier.
Since you've done all that, we don't know what's wrong with it. 4.0.2? You're missing out on security fixes (been talked about a lot lately), new features, optimizations, not sure why you're running it. That aside, and I'm not saying it will do anything for you, you could try GetRil from the Play Store, to see what RIL you have installed, and if it recognizes any baseband at all. Your radio (or radios, we don't even know which variant you have) may be dead, who knows? What's the latest baseband you flashed? What's the latest bootloader you flashed?

I wanted 4.1.2 but for some reason I got 4.0.2 so I have no idea, but I'm going to stick with ice cream sandwhich since 4.2.1 update had tons and I mean TONS of bugs that wanted me to kill my nexus.
Build Number: Android revolution HD 2.1.2 GSM
aNDROID vERSION: 4.0.2
kERNEL vERSION: 3.0.8-GAAA2611 ANDROID [email protected] #1
IMEI: UNKNOWN
IMEI SV: UNKNOWN
I have flashed versions:
UGKL1
UGKK1
UGKM1
(All are for I9250M GSM not LTE or CDMA since my phone is GSM)
I have Clockwork Mod version: 6.0.3.1
Bootloader PRIMELA03
Baseband: I9250MUGKL1 (According o bootloader, still unknown in About phone)
... and install the app GetRil. Not sure, but I think you should revert to ICS boot loader.

Hello, yeah I got the app, but it says that they dont match and they show basband unknown compared to ugkl1. How do I get the ICS Bootloader?
See the sticky by efrant (android 101; useful links)

[Q] Latest Baseband GSM Gnex

I have the GSM variant of the Galaxy Nexus running 4.3 on T-Mobile. I have been having some issues (before and since 4.3) where the signal drops and it's just gone. Rebooting sometimes works. APN settings are correct. Nexus 4 has no issues, so it doesn't appear to be a carrier issue. Trying to figure out the latest baseband version (currently I9250XXLJI). As always, any and all help appreciated.
That is the latest version. The baseband hasn't changed in a long while (that's the version that comes with 4.3 even).

I had the same problem a long time ago. Tried flashing different roms, changing radios and even bootloaders. The only thing that helped me was going to t-mobile and asking them a new sim card. After that I never had any problems with my connection.
Thanks for the information. I wish I had seen the replies sooner. I've had that sim card for a while and it's probably time for a new one anyway. Thanks again.
