Hey,
I am using ATT s3 with CM10.1 1/15.
I used to get LTE, and now I have a problem.
Most of the time I get 3G or H or H+, then if i disable and enable LTE I do get it, but then it reverts back to 3G or H or H+.
And every time I want LTE I have to disable enable it.
Anyone else has the same problem?
Ts there a fix?
Thank you
Try flashing a different modem

So I was able to do this in stock via *#2263# but the lte toggle or even the use only 2g networks options wont work in cm9. I typically just use 3g because I get ridiculously better battery life and would like to be able to do this on cm9 as it is my favorite rom. Any help would be greatly appreciated thank you all.

I am not sure if this is the right place to have this but I have a tmob s3 that I am trying to get the 3G on att to work. I know the lte won't work but the hspa should thou since it has the proper bands for it.
I have been able to get the 3G to work by manual setting it by the dialer but it won't make calls until I set to it back to automatic it. It won't go back to 3G until I manual set it back
I have tried every apn settings and nothing doing...
I am not sure but maybe I need to try a different radio? I am currently on the latest jb radio.
Any ideas?

I think you need to make sure your phone sim is unlocked. You can do it by some method on these boards or you can call your tmobile and ask them for the unlock code.

If its unlocked you should only need to pop the att sim card in and it shoudl automaticly set the att apns(on CM10 or any aosp rom, rebuild TW rom), and get hspa+, tho if your on stock rom you need to add the apns manually since the apn.xml inside framework-res.jar dosnt have them.
Yea its already unlocked and it gets service it just doesn't make the switch to hspa+ unless I manual force it to do so and it doesn't always work sometimes it will show now service

im having the same issue, how do i manual for? im running on 4.12 aokp
I have read the countless posts on the 3g issues, but when I try to access *#*#4636#*#* and change to wcdma only or preferred it won't stay the option just instantly changes back to CDMA and won't stick.
I was on paranoid android and flashed the cm10.1 12/08 nightly hoping the fix would work but it hasn't really. I read of a flashable fix and was hoping to get that but the link is down. Not really sure what to do at this point and I don't want to go back to touch wiz

Not sure wat 3g issues u speak of... 3g should be the least of ur concerns on cm10. Changing the settings in *#*#4636#*#* is temporary. Use the network selection mode under system settings in cm10. Ur problem is most likely not from 3g but from the hand off from 3g to (ehrpd) to lte and any combination of the above. It is a known issue even if ur not in a full lte covered area yet. The APN is not configured properly. http://forum.xda-developers.com/showthread.php?p=35205882.

And I'm pretty sure there's an apn commit being entered in the next nightly that addresses the problem

As a user the problem manifests itself as me not being able to get 3g back unless I reboot so that's why I called it a 3g issue, sorry for not using the correct jargon. But thanks for the link.
The zip in that link worked temporarily but now I'm back to the same issues but worse because I completely lose all radios a few times a minute, except WIFI when lte is off in settings. When lte/cdma is selected in settings I have the same issues as before.
I think at this point I'm just going back to a touch wiz Rom it's not worth the missed calls and text messages to be on an awesome Rom. When my phone came back on from the fix i had like five text messages pop up from last night. And now I'm always just going to winner what I missed. I heard this bug mainly affects non touch wiz roms

I flashed the urban karnage 1.5 today and now my cell signal is no longer set up correctly. This rom does not let you set you manual apn's. Anybody's thoughts on why I am only getting 3g where I used to get lte?
Thanks

I managed to get into the APN settings and make the correct changes but it was useless I still could not get on the HSPA network that I could get on my stock rom
I've noticed that whenever I turn off my wifi that my phone always goes to edge even if I have 4G coverage in my area. If I want it to switch to 4G then I have to either toggle airplane mode a few times or reboot. I'm running Jedi 12, but it also did this to me on CleanROM 4.5. Anyone else have this issue?
