Arrow [HowTo]Network Setting Change 2g/3g

How to unlock settimg for 3g and 2g on Atrix 2:

*Disclaimer * The publisher is not responsible for any damages to the phone. This modification has been verified, but please do approach this tutorial with caution.

+You must be rooted+

Read first, Do later.
If you do not understand what is going on in tbis tutorial, then it will be extremely risky to proceed.

-------------------------

File: /system/etc/motorola/com.android.phone/defaults.xml

Setting: - Unlocks the mobile networks, 'Select network' and 'Operator selection

Code: <boolean name='network_select_menu' value='true'/>

1) Edit the following files:

/system/etc/motorola/com.android.phone/defaults.xml /data/data/com.android.phone/shared_prefs/settings.xml /data/data/com.android.phone/shared_prefs/com.android.phone_preferences.xml /data/data/com.android.phone/shared_prefs/_has_set_default_values.xml

Setting:

2) When I initially tested, I found that the files would revert to their original state after rebooting, but on http://forum.xda-developers.com/show....php?t=1108181 member liranm2 states that YOU MUST DELETE THE BACKUP XML FILES THAT ROOT EXPLORER CREATES.

3) Reboot phone.

In summary, the above changes provide un-greyed options under Settings, Wireless & networks, Mobile networks as follows:

1) Select network 2) Operator selection

'Select network' provides the following options:

2G only = GSM only = lowest battery consumption, with slowest data speeds 3G only = WCDMA only = highest battery consumption, with fastest data speeds Automatic = GMS auto (PRL) = medium battery consumption, with fastest data speeds when 3G towers are 'preferred' over 2G towers. This is based on what the towers advertise as being available. i.e. if a 2G tower has a stronger signal than another 2G/3G capable tower, then use 2G.

Automatic uses less juice becasue:

1. 2G uses less juice 2. a stronger signal will yield lower transmit power consumption by the phone, i.e. don't force 3G if there is a stronger signal available at 2G.

'Operator selection':

Search networks = see all of the providers that your radio is compatible with, i.e. providers transmiting on frequencies your device supports. Select automatically = will prompt every time your phone moves between different services that your provider offers that are not considered roaming.

On AT&T's network, using Any Cut to run Activity, GSM/UMTS Options provides a slight variation of the above menu. This can be used without modifying files. Instead we get a 'Use only 2G networks' check box which causes the phone to switch between GSM Only and GSM auto (PRL).
As always, "Thank You, Come Again".

I don't have a /data/data/com.android.phone/shared_prefs/settings.xml file, and didn't make one, but I made the change in the other files and it works!
Thanks

Install an app called "network" by Philipp Mangelow from market.android.com, and change the 'preferred network type' to "GSM only". It works in my unlocked A2. You can also toggle b/w 2g & 3g.

Yes. It is "wcdma preferred" for selecting either 3g or 2g. If you want only 3g, then it is "wcdma only". It works in my A2.
