[HOW-TO] Easily change network mode (GSM/LTE/WCDMA) from stock AT&T ROM

Hi,

I have owned this device (S2 Skyrocket i727) for 3 years now. It is still an incredible phone for daily usage.
One thing that has bothered me is the difficulty in changing network mode in the stock AT&T ROM.

One elaborate way to do that is dial *#*#4636#*#* and choose the network mode. But this is a pain to do everytime.

I have found another easier way. Here are the steps.

1. Install Nova Launcher (Play Link) or any other launcher which allows adding Activities as shortcuts


2. Create a widget and then select activity


3. Scroll down to UltraCfg -> Network Settings (network.NetworkSettings)


4. Done

Sample screenshots from the widget.





Hope this helps!
