lol Wish I found out about this super secret section of hidden menu a long time ago. Might have helped me fixed the first phone that had the network problems. Most of the things in the "CDG2" hidden menu contain LOTS of things normally found by editing them with QPST. Now I only looked at most of the settings. Since I have a working phone and don't want to have a not working phone, I did not mess with most of the settings so user beware.
In service programming you can find a "Phone Reset" option. So if your phone is screwed up in a manner similar to how mine used to be, then it "might" help fix it. The phone's mode for data can also be found in here. Mine is set to "Digital Hybrid" which was a setting I tried forever to find via the normal dialer code methods for my broken phone. It may have solved the 1x issue I had near the end of my work with that phone, but now it's irrelevant due to having a new phone.
Anyway here's the screenshot by screenshot instructions on how to add this kick-ass hidden menu settings with the menu option to select circled in red: (You must have ADW Launcher or else you won't have the option of creating custom shortcuts like what's about to be shown)
Step 1:
Step 2:
Step 3:
Step 4:
Step 5:
Step 6:
Profit!
Now any one know of a app that can create custom shortcuts in a manner similar to how ADW Launcher does it? I am currently using ZV4 Murky Beats 1.2 and I rather like the Xperia launcher so I don't want to keep ADW for this.
Also note that this method does not appear to require root (since I did not see any Superuser prompts). I also did this on MB 1.2 rom so I don't know if this will work with stock rom or not since I have not tested it in stock rom.
If you scroll further down the list of hidden menu sub menus, you will find an alternate version of "Network Select" that will have a P_Rev and EVDO_rev option. Not sure what these did. Only setting I tested was EVDO_rev (which changes the revision of EVDO?). It did not have any effect and phone status still shown the EVDO revision A when I had changed it to B. So it does not seem to hold that setting or perhaps it's network related and there's no EVDO_B towers in the area so it keeps the rev A setting. Not sure what it is, so I don't know.
If you look in the CDG2 menus, you will find a SPC code setting which appear to allow you to change your SPC code for the phone. Since I kinda like my SPC code and for safety sake, I did not test this setting. So there's a chance it serves a different purpose, but most likely changing the SPC is what it does.
The CDG2 menu does not appear to have a dialer code associated with it (that I know of? At least for Boost phones there isn't), so this is the only current way of getting to that menu.
