Rooting and Band Selection

I have exhausted every option known to me trying to get access to manual network band selection on the Captivate. The usual codes take me to the correct place, but I get an error message saying it's restricted. My question is will rooting the phone give me access to those menu options? I want the ability to lock the phone to GSM/EDGE or WCDMA at will. If anyone knows a solution to this, please let me know. To clarify: I am not looking to just turn off data and the *#*#info#*#* route doesn't work. Thanks.

Can anyone with a rooted Captivate confirm that you can or cannot access the menu to lock to GSM?

Hi,
No need to Root the phone at all. Just dial *#*#4636#*#* then click on "phone Information" scroll down to the drop down menu & click on it, click on "WCDMA" only & go back. done

This does not affect our phone. It does nothing.

What do you mean by "it does nothign"? I did it & working.

Setting 3G only or 2G only
I found out that if you go into the dialer and type in *#*#197328640#*#* that it will take you into a menu that will allow you to change it. From the main menu of the ServiceMode screen, select DEBUG SCREEN, then PHONE CONTROL at the bottom, then UE STATE CONTROL. From there select CHANGE RAT TO WCDMA to enable 3G only, and select CHANGE RAT TO GSM for 2G only.

THANK YOU!!!!!!!!!!!!!!!!

Doesn't survive a reboot but it's a start.

thanks for this.
but to take this a bit further, is there any way to automate this via a widget?

^Not from a widget in the market
They tend to wind up turning data off all together. Im sure it can be done though

Phone settings, wireless and network, network mode. I don't know if it's present in all roms though. There you can change the network band type

You have been mixed up....
Clear your mind,
*#????# - service menu is service menu,
root is root,
These are two different thing.

I'm not sure if band selection is disabled on all Captivate roms (it definitely is on some) but I have ran a number of I9000-based ones, all of which permitted band selection. Try dialing *#2263# to enter service mode and see if you're able to select the desired band. I'm using Perception 10.1, on which I can use this to modify the band settings and it is retained through a reboot.

I'm running perception 10 and there is an option in settings>wireless and network>mobile network>network mode> wcdma only or GSM only or auto.

Band selection in settings is only in I9000-based roms!!! It's non-available in Cappy-based roms!

Engineer/Debug codes

Just curious if anyone knows other engineering/debug codes like, *#*#1472365#*#*, used for the GPS settings. I just want to know what else exsists..

Got this from another source.
Be careful what options you change.
*#*#4636#*#* for battery and other general setttings like GSM/CDMA
*#*#8255#*#* for Gtalk service monitor
*#*#7780#*#* for factory data reset
*#*#34971539#*#* for information about phone camera (be very careful hitting options here)
*#*#7594#*#* change the "Power" button action in your phone.
*#*#197328640#*#* service mode
*#197238640# service mode
*#0*# testing mode
*#06# view IMEI number

Working Dialer codes

On my quest to find the SIM unlock for this phone I've started testing all the dialer codes I can find. I haven't found what I'm looking for yet, but these might be useful to you guys for other purposes.
*#0*# General Test Mode
*#0011# Displays Network status
*#0228# Battery status
*#06# Shows IMEI
*#1234# To check Software and Hardware information, PDA, CSC, MODEM (Firmware Version)
*#12580*369# SW & HW Info
*#2663# TSP / TSK firmware update
##3282# data programming
##33284# debug. Password is 777468
##3424# for mounting options (diagnistics modem)
*#34971539# Camera Firmware Update
##72786# clears provisioning data, doesn't require MSL, automatically reboots and reactivates
##786# complete factory restore, requires MSL
*#7353# Quick Test Menu
*#9900# Sys Dump Menu
*#9090# Diag Config
If you've got any that you've tested post them here with a brief description of what the code does. I'll update the OP with new codes.

##33284# debug. Password is 777468
##3282# data programming

##DEBUG# password spells out "SPRINT" in case you forget
##DIAG# - for mounting options (diagnistics modem). Used to be ##7887# on GS1/GS2 and maybe GS3 I forget.
##RTN# - complete factory restore, requires MSL
##72RTN# - clears provisioning data, doesn't require MSL, automatically reboots and reactivates
OP please keep your post updated for easier reference.

Used the ##72rtn# code you shared and it saved me. I had a Ghostbusters symbol for my signal bars and no cell service. .. now all is good. Thanks

Glad it helped. There really should be a master list of these dialing codes. One that has helped me greatly is the one that clears GPS data (for when GPS won't lock)

*#03# NandFlashHeaderRead
NAND Flash Unique Number
15 Digit HEX Value
Used to prevent Nandroid backup being transferred to another device???
EDIT: Does not seem to work anymore after MF9 update

Not sure how "Master" of a list it is, but thought it was worth noting here.

Widget to toggle advanced calling?

Anyone have a widget to toggle advanced calling?

I would also be interested in this

Yeah, I think it's essential. Call quality sucks on advanced calling, and for important calls, I want an option to quickly switch to 1x calling

Anyone else have any ideas?

This would be great. I am also looking to get tasker to toggle it for me when I am connected to my home wifi (and others) Since you only need it when you have no wifi.

Sounds like a tasker problem

I suppose it's not available in tasker after all. Weird BC I thought nothing was off limits in the app http://forums.androidcentral.com/android-apps/538920-how-can-tasker-programed-toggle-hd-voice-lg4-widget.html
So unless you're a developer, I suppose there is nothing you can do to get a volte widget.

I know this is an old thread, but I came across it because I was looking for the same feature. I have Verizon, and I have a Network Extender in my house to get normal service. Well, one of the downsides of using an Extender is that you have to have your Advanced Calling turned off to connect to it. Because I want to toggle it on and off frequently, I wanted a widget on my desktop. So I found a solution after trying a few apps.
Solution:
1) download app called "Quick ShortcutMaker"
2) on top, change search from "incremental search" to "normal search"
- this is easier, because you would think you could access it through settings, but you can't because its not there
3) type in "advanced calling" and search, you'll get two matches
4) choose the 2nd one which is labeled "Phone -> Advanced Calling -> com.android.phone/com.android.phone.VzwAdvancedCallingSettings
5) put that shortcut on your desktop and now you have a quick toggle to jump to that page and turn it on and off. Its not an official toggle, but it does save you several screens
PS: you can do the same for WiFi calling. Just make sure when you search that you search for "Wi-Fi calling", the hyphen is important. It's also under the phone category.

I just upgraded my Vz network extender to the new 4G model. It supports advanced calling. It also fixed a problem that I had sending DTMF to an IVR system.
I sold my old 3G network extender on eBay.

I wasn't aware of a 4G model. I would like to look into this. Could you share with me the manufacturer and model # of it? I can't seem to find on google.
Update: never mind, think I found it...this one right: https://www.verizonwireless.com/accessories/samsung-4g-lte-network-extender/

Awesome!!!! Been looking for this a long time. Still having trouble with my junk advanced calling. Works great even though says for older operating system. Now You have to add the widget to home screen first and then select it to add shortcut. So happy!!!!!!!!!!

US Cellular Note 5(N920R4) ON CRICKET - keeps switching to Verizon -

I have US Cellular N920R4 (NOTE 5) and trying to get it to work on Cricket -
Step 1- The phone was factory reset before putting in Cricket sim, after booting under setting >> Mobile Networks>> Network mode - I set it to LTE/GSM/UMTS
Step - 2 Under Network Operators - I selected the manual option and searched for providers - the search showed AT&T, Verizon and US cellular - I selected AT&T
Step -3 Under APN - I manually added Cricket APN -
Now I do get AT&T for a short time, I'm able to make and receive calls and SMS - Also get 4G in my menu - but after a few minutes I loose AT&T and the phone reverts to Verizon -
Can someone suggest what could be the issue ?
Also can someone share how to get to hidden menu band option (On other versions it is possible to get to it using *#2263#) and is there an option to change "System Select" under mobile networks to be changed from "CDMA roaming mode" ?

There's an app in the playstore called Samsung Phone Info and it has a function that will launch the full service mode root menu allowing you to get to all the available service screens, I'd just search that and download the free version by vndnguyen....

Please any other recommendation from XDA members -
Is there a way to change the "System Select" option ? comment below this option indicates "Change CDMA roaming mode"
