Stuck on 3G after JB update and using Phone info app

[SouthFLpix]

Basically I am unable to log into LTE after using the Phone Info app to force a 3g connection. On ICS I was able to switch back between LTE and 3G without a problem. With JB the phone is stuck on 3G and won't go back to LTE.

I did a 'google search' and found others with the same issue here: Stuck on 3G after Jelly Bean upgrade! - Android Forums at AndroidCentral.com


One fix (for other versions of the S3) seems to be going into settings/more settings/mobile networks/ and choosing LTE directly from there. Unfortunately this option is not available on the Metro version of the S3.

So what are my options? Is a factory reset the only way?

I tried it, but unfortunately that app is not compatible with the S3.

Try this: Download the app anycut then go to IOTHiddenMenu then from there try LTE Mode Menu then enable lte mode

When I try this I get the message, "Could not launch the requested activity."

Go to the dialer and we dial *#22745927<--- thats still the same code still being used on ics still works now u should get a menu box that looks like this just enable hidden menu

I did that, and got the 'hidden menu' screen and enabled it.

However, when I tried Anycut to access the menu, the only difference is that it took me to that same 'hidden menu' screen (which still says 'enabled'), but I got the same, "Could not launch the requested activity" message on the hidden menu 'screen' (if that makes any sense).

Ok, I've restored access to LTE by doing a factory reset. As you can imagine, it was definitely kind of a pain. For now I'm going to uninstall the 'phone info' app, and I recommend that everyone else on an S3 with JB do the same.

We'll have to find some other way of enabling 3G and 4G, I suppose.

Well, I'd say about 95% of us won't being doing anything to get us throttled on FoGee! and Need to purposely go to 3G...

I just tried Quickshortcut and it worked great. I was able to create a network toggle shortcut that works with JB. Thank you!
