Toggle between 4G and 3G - Verizon Samsung Galaxy S III

Hello everyone
I was wondering what a good app was for switching between 4G and 3g on my phone.
I have rooted it but have not flashed any new ron onto it yet, however I was thinking of throwing cm10 onto it.
Thanks for the help

Did the settings for mobile network get changed somehow? Check under wireless settings and make sure the box for using mobile network is checked. If not you may have to Odin back to stock with modded 3e and root.

att stock firmware has issue to create a new fake new invalid empty apn
I just bought my first infuse yesterday and i really like it only one problem though it wont connect to data with my personal sim but when i put my company sim in it works is there an app or download i can install to override this issue or do i need to get a new sim card? Btw the company sim card that works is an old 64 cingular sim card and the one that doesnt has 3g att on it . Any help is appreciated thankks Sam
That doesn't make sense. Call ATT and tell them your sim doesn't work.

I can't remember, neither of us have infuses anymore. We switched to SGS2's lol.
I think its the one in the MIUI thread.

[Q] Xoom 4G chip Swap help

Please help.
My first XOOM (Verizon 4G LTE) got sort of smashed in an accident.
I found a second Xoom to replace it with, activating it with no issue (3G).
The problem I am having is the 2nd Xoom has not had the 4G upgrade done on it.
So I took the 4G chip off of the motherboard on the "old" xoom and installed it on the new Xoom.
I then popped in the SIM card and "Activate"d it.
It is not seeing the 4G LTE. I am assuming there must need to be a firmware upgrade of some kind, but I have no idea where to find it or how to install it.
Does anybody have a clue on this?
Thank you.
But 3g works? Like ur 4g chip seemz to be doing fine?

Yes, the 3G has always worked fine. It's just that the firmware does not recognize the 4G chip, so ONLY 3G works.
I'm hoping I can download and install the firmware without having to root the device.
Even if u flash a 4g rom only 3g works? Did u try playing around with the frequency bands? Btw goood job with successfully replacing the chip !

He hasn't flashed a 4G enabled ROM because he doesn't want to root.

That is correct, although after talking to a Verizon tech tonight, I don't think I will have a choice.
Is there a solid ROM out there? From everything I've been reading, sacrifices are made with these ROMs like lack of WiFi.
you don't need to root to flash a 4G rom....
you only need the stock 4G rom.
here is a link to the Motorola page to get the rom and how to flash.

Wait so it will not work with the generic icons? That is a shame, because the generic icons allow saving of phone numbers to default to Google not the phone. To me this is more valuable than att hot spot. They make me pay for a 3gb LTE plan without offering LTE in my area, I never exceed 1/2 gb on a given month.

Try the wifi tether app available for download on Google code. Set its setting to generic ICS and it'll still let you tether just not through the wifi hotspot app

Wow I'm so sorry! I re-read your OP and realized you're asking something completely different than what I answered.
Try downloading the my Att app or some other att wifi hotspots app that I can't remember the name of right now. Ill have to get back to you tomorrow about the name exactly.

[Q] SHOstock3 with no 4G signal

I been using my s2 SGH I777 with ATT for more than 2 years with a new SIM and 4G, then started to use SHOstoch3 (last Version) and I have just a very poor 3G signal. Any ideas? I know it's not the sim because it was working fine! Thanks
I am having the same results...Just 3G or H+. I was wondering if there is a way to get 4G back?

Tested yesterday to factory reset the phone with a new blanc installation of 2013/10/04.
Got no signal, the shown provider was verizon instead of vodafone. Dont if there were any changes in support of german/europe frequences?
Was gone back on my backed up version from 2013/09/01. This has higher batterycdrain and lower performance, but all is working.
Ideas anyone?

Installed latest update 10/05, 3g is working again. Rom Performance looks fast.
