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

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.

I bought an unlocked yakjuux Galaxy Nexus (Canadian) phone that currently has 4.2.1. From what I understand, Samsung is responsible for doing the OTA updates, which I know unfortunately occurs later than the Google ones. I'm using this phone on T-mobile in the United States, and I wanted to ask if this will interfere with me getting any updates, since I'm not using a Canadian service. If not, I'm willing to wait it out. If not, I'm considering flashing takju or yakju. Does flashing these images also change the radio, or is that a separate process? Thanks in advance.

That's actually a separate process as Roms normally only package kernels and even then is optional.
If you search the android development forum you'll find the radio thread and likely find the radio you need to flash. I would link but on mobile.
Also I believe Rhee only difference between yakju and takju is Google wallet. I actually think Google factory brands every phone with any JB stock rom. (Eg. No longer rogers/bell/fido etc boot screen and bloatware.)
So unless you flash manually I'm not sure you'll get OTA because the Canadian OS for me on wind and rogers has only updated to 4.1.2 because of the 4.2 bugs.
EDIT was 4.2.2 but when I got OTA it changed to 4.1.2, I now use the cm10.1 so I'm not much help anymore.

Thanks for the reply. Is there an advantage of me flashing a new radio?
Also, if I understood the last part, I can get OTA updates from my Canadian phone, even though I'm on a US network, but they've delayed the update because of bugs.

No problem! All it really changes is how it deals with reception, any radio can be flashed with any ROM, personally I'd recommend the latest, doesn't destroy your battery as much on 3G anymore.
And it does seem plausible to receive OTA if its not rooted and still on stock because the factory images come from Google now. (International)
But yes that's correct, as far as I know wind (my carrier) has only gone to 4.1.2 my roommate has this same phone officially from wind with 4.1.2 and we just clicked system update saying it's latest.
Rogers may be different however I changed my phone from a rogers gnex to my own little wind gnex
Hopefully you fix your issues!

I just bought a Samsung Galaxy S3 i747 from Amazon. It is an unlocked GSM version.
Problem is it has a Canadian baseband version, and I am in the US on AT&T.
I have a problem with data connectivity, and according to Samsung tech support, it is because of the Canadian firmware/baseband version.
Can I change the firmware/baseband version from Canadian build to US build?
If so, how would I do it?
Thank you for any help.
What is the ROM and baseband on your phone? Can you make phone calls?
I could be wrong, but based on my experience with the T999, that shouldn't be working. While flashing a T999V baseband won't hurt it, it simply won't work.
Please tell us your current baseband, current rom, and current firmware build. Enter this in terminal emulator to determine base firmware build,
getprop ro.bootloader
Also, can you verify by the sticker under the battery that it is an I747 and not an I747M?

Yes, I can make phone calls. I get 4G data connection, but it is slow and keeps dropping, even though it still shows 4G.
If I swap the sim to my old phone, all data connections work great, so I know it's not the sim or the network.
It is in fact an i747M

Ok! Everything looks like it should. You could try updating to the 4.4.2 build, but keep in mind you cannot go back to 4 3 afterwards. (You can flash older ROMs but not firmware). And do not flash a 4.4 2 modem on what you are running now.
You can flash the ROMs built for the i747, but for the modem you can only use the I747M.
If the store you got it from told you it was an I747, you might be able to return or exchange it due to incorrect listing.

It was sold as an i747, not i747M, so I will just return it.
The modem is what connects me to the network, so if it remains the Canadian version, changing the firmware won't solve my issue, right?
Thank you for your help!
All I can say on that is you should never flash any firmware that is for any other model device. Its just not safe to do and will almost always cause a hard brick.

So basically, if you're unable to use it as it currently is, I personally think the best option would be to return it and try to get the US I747 model. If you go in and try changing the firmware and it ends up bricking, you'd probably lose the ability to return it, so IMO its just not worth the risk.

I am going to send it back tomorrow. I don't want to have to flash anything. It should have worked right out of the box, so I'll just return it.
Strange that the Canadian version didn't work as it should. I have an HTC Desire A8182 that is a Telus version, unlocked, and it works just fine on AT&T. No data issues at all. I rooted that one as it only has 100MB internal memory, and I wanted to get rid of bloatware and use Link2SD plus to move apps to the SD card.I didn't use a custom rom, just rooted stock firmware. It's still running 2.2 FroYo, and I love it! It's only 3G, and a tad small, which is why I decided to go with the S3.
Thanks again for your help!
Seemed a little odd to me as well, but there have been a lot of upgrades and enhancements done to many US networks that may not have been done in Canada. Its just a theory, but I747 firmware may have been built to take advantage of that and the I747M might be made to work better with older or just different networks. Kinda hard to explain what I'm thinking here...
Its also possible that the US and Canadian 3g networks are more similar than their 4g ones, which might explain the different experience with your older device.
And then again, you might have simply received a device that had something wrong with it, which you'd want to return anyway I'm sure.

I sent it back today and the seller will refund me when they receive it.
I found an interesting tidbit on the AT&T forum regarding the S3.
"The international edition won't support LTE bands"
Ordered a US version (presumably, lol) today.
Hi all,
I have two Boost GS3 that I have rooted and loaded CM11 on and am having issues with LTE on one even though I have updated the APNs and have tried different roms. The only difference between the two is one is running baseband L710VPUCNJ3 (LTE works on this one) and the other is running L710VPUCNDC (3G only). Not sure what else to do. It's funny because LTE worked on both of them shortly after I rooted and flashed but my phone lost that ability at some point. MMS works and I can not change the APN on my phone as nothing shows up. I think it might be worthwhile to upgrade the baseband to the same NJ3 version but I am having trouble finding it.
Any ideas? Any help with this would be appreciated!
