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 want to save battery life ....
I do not know about the app but there is one problem. Sometimes I download large files and i do not want to keep my screen awake all the time. But if it switches the connection to 2g from 3g (or vica versa) it disconnects for one second and the download fails.. So that could be a problem for downloading large files.

if can set the timer,that problem can fix
Juice defender can do that I think. Haven't tried it myself I don't use that app anymore, but I believe there was an option in it to toggle between 3g and 2g. However, you have to have root access and a kernal/rom that supports it. Stock kernals don't support allowing you to switch between 2g to 3g without doing it manually yourself through the settings, so you probably need to find a custom one that does.
Im using easy battery

You'll need a mod ROM to get full use of Tasker for battery improvement. Stock ROM doesn't allow 2G/3G switching.
I understand that CM10 allows this.
Someone should confirm, as I've stuck to rooted stock rom in SIII and plan to keep the same on Note II.

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
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

After restoring a Nandroid of cm10.1 my phone is now stuck on 4G. Data and texts work fine but I can't make or receive calls. If I toggle LTE off in mobile network settings it automatically puts it back on. Same thing if I toggle only use 2G networks.
I imagine this has something to do with me going into the radio dialer settings (the settings page you get on touchwiz by dialing *#2263#) but am unsure.
Is there a way to access that screen or one that has similar function on cm10.1 so I can test? Or do I need to flash a TW ROM and change it back? And to what, automatic?

*#*#4636#*#* gets you into the testing menu on CM10.1 where you can then go to phone info and change the preferred network type.
Ya I tried apns, sim resets, really anything I could think of that's connected to the radios. *#*#4636#*#* had the same results as the toggles in settings. It would automatically just switch back to lte.
In the end I just reflashed a touchwiz ROM, went into *#2263#, the LTE band had an * beside it. Hit automatic and Nandroided back to cm. Everything working fine now.
I guess those settings are on a hardware level nandroids can't get at. Live and learn.
