I Need to know what the Stock settings for modem are. I was messing and now things don't work.
Here's my settings. I haven't messed at all:
Modem Settings
Slot Cycle Index - 2
Preferred Serving System - Automatic
Preferred Mode - CDMA only (i did change this with *#*#INFO#*#*)
Preferred Mode(9k) - HDR Only
HDR Hybrid Preferred- Enable
HDR Hybrid Preferred(9k)- Enable
Clear all MRU Entry- No
Rev. A- eHRPD
1x Diversity - Disable

I need some help modifying a Froyo rom to include a "GSM only" setting.
The background is that under certain conditions (i.e. intermittently), the cell radio shows full connection, but will not allow calls, incoming or outgoing. I finally narrowed a workable solution down to forcing "GSM only" (vs. auto selection of CDMA and GSM networks). But I can only get there at the moment by adding the "Phone info" custom shortcut to my home screen (ADW Launcher) and going in and setting it manually. And unfortunately that doesn't always survive a reboot either.
I would like to simply pre-set that in the rom and not have to re-set it again. I had assumed it was something that could be done in one of the init or prop file, but I have thus far not been successful in finding information about where and how to do that.
Any help would be appreciated.
Solved. For anyone else who stumbles upon this question, the setting in build.prop is:
ro.telephony.default_network=#
Where the # is a number code for which setting you want. In my experimentation for my device, "ro.telephony.default_network=0" is WCDMA preferred and ro.telephony.default_network=1 is GSM only.
I "think" the other codes are as follows (but I can not confirm this):
0 WCDMA preferred
1 GSM only
2 WCDMA only
3 GSM auto (PRL)
4 CDMA auto (PRL)
5 CDMA only
6 EvDo only
7 GSM/CDMA auto (PRL)
8 Unknown
Additionally, if you want to set it temporarily while the phone is running, you can launch the phone info settings by entering this on your phone's keypad:
*#*#4636#*#*
But I believe it will revert to whatever you have in build.prop at the next reboot. No matter what you set in build.prop, you can still go into your Wireless & network settings, Mobile networks, and click on or off the "Use only 2G networks" setting.
Anyone know what the options are for the portion in build.prop "# Default network type"?
I'd like to switch it to GSM/UMTS as the default.
And is there a way to stop it from auto switching to global or CDMA when it can not find a GSM/UMTS connection/network?
Or, what would the options be to disable switching or CDMA altogether?

I for one dont feel the need for LTE myself yet. Perhaps if im dling a large file or something i would want to use it, but my ever day activities that i use my phone for, 4G(HSPA) does just fine. So i decided to do some tests. The main reason i would turn off LTE and just use HSPA is id assume it saves battery. Ive come to this conclusion knowing LTE requires more phone power to hold the signal, and also the conclusion that when im on LTE, my phone signal is always significantly lower then when on HSPA. 1/2 bar vs 4/5bar normally.
How id normally turn off lte was using a shortcut to the Phone Info menu. Where you could change network modes. By default it is LTE/GSM Auto(Prl). I would normally set it to WCDMA Preferred to have it only use 4G(HSPA). However every reboot would reset that.
Until recently i found the Network Mode option within the settings menu. Wondering what the differences are side affects are, or if one mode affects the settings of another. So far ive found that the Network Mode and Phone Info modes are some what linked.
Network mode is under Mobile Network within the More Wireless Settings.

Tried but in vain
when i am setting the Set Phone Info Mode to anything other than LTE/GSM Auto(PRL), it resets back to the default setting which is LTE/GSM Auto(PRL) as soon as i exit the phone information screen.
In the Phone info settings (accessible by downloading the "Hidden Menu" app from the Play Store [I tried phone dial codes, but they didn't seem to work on my custom ROM, Mahdi ROM]), you can change the preferred network type from the default:
LTE/GSM auto (PRL)
To a variety of other things, including LTE/GSM/CDMA auto (PRL).
I'm on AT&T. Presumably, the G2 is a world phone, and thus could pick up CDMA signals. Would enabling the LTE/GSM/CDMA preferred network type bring any advantages, like improved network coverage, or any disadvantages, like worse battery life?
Phone: Unlocked 4a. Network: Verizon
I have a macro that enabled me to switch between 4g LTE and 3g by toggling the value of the the system setting "preferred_network_mode" between 8 (LTE,CDMA,and EvDo and 4 (CDMA and EvDo). I also would toggle preferred_network_mode1 and 2 as well. Then, switching off and on airplane mode would enable the setting.
After the upgrade to android 12 (or possibly one of the monthly security updates) I can no longer force 3g. The preferred_network_mode value gets updated to 4, but the phone does not change from LTE, even after a restart.
Is there another setting that must be changed in 12 to enact that network change or did they kill that functionality altogether?
And before anyone asks - I know 3g is dying, but I live in AZ and many rural areas have no 4g but still get coverage fine with 3g. I'd like to keep using it until VZW turns it off completely.

Can't you just change that on SIM settings?
There's an option there to choose the preferred connection type. If you choose 3G there, it doesn't work as preferred?
I thought that was that option porpouse.
Cheers!
The SIM settings only allow Global, LTE/CDMA, or LTE/GSM/UMTS.
There is no CMDA/EvDo option.
Manually setting the preferred network mode to 4 should override those options and force CDMA mode, unless the system variable that determines network mode has changed with Android 12.
