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

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!

[Q][SOLVED] Update the phone number after porting

I recently had my old phone number ported to my new network, but in the Settings -> About Phone -> Status screen the phone number is still showing as the temporary one assigned by the network while I was waiting for the port, which was different to the SIMs original, and it changed then.
Is there anyway to get this to update? I've tried restarting the phone, with and without the SIM in but it's still showing as the temporary number. The port has definitely taken place as people have phoned me on my old number and I've phoned them and it's shown as me.
Any help greatly appreciated

No-one know then?

It sounds to me like this may be something that is programmed into the simcard and doesn't change when the operator changes the number (or something like that). I doubt you will be able to fix it yourself, seems to me that this is either due to some delay in the operators system (unlikely after 4 days) or its just coded on the simcard and doesnt change. Maybe there is a program to edit that somewhere but I have no clue.

I've had almost the same problem since the beginning. There's no number on the info field.
I had a new contract and a sim card for the phone, but there was no number. I also have no idea how the number is defined in the field.

Try This and see.
Australian Sim Cards do not have any number Details Programmed so you may be able to program the Sim via your Phone.
Go to Contacts -> Menu Key -> More -> Settings -> Own Numbers.
Here you may see your old Number. Just open this and change the Info and Save.
you may have to Reboot to see any effect.
Keep us updated if this change works.

Hi, I have the same exact problem as above when I had my number ported to T-mobile. I was really searching for a way to fix it then I came across this, I tried this but I do not see that option for me, do you know of any other way to update or fix this? I find it a bit annoying haha. Plus I want to root and do not want any possible mishaps. I am on the Galaxy Note 4 by the way. Thank you.

I rooted and it was fine so I am happy there but I still do want to update the number. Recently I sent my friend a picture message and she got it form my temporary number and it annoyed the heck out of me, a few minutes later I resent one and it was fine so I guess it was a tiny mess up. I wonder if going in and buying a new sim or something would help because if it does and the sim is $10 I'd be willing to do that.

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..

I agree and tried but google really doesn't like when you put * or # in the search bar. Even with quotes around them.

There's some listed on the Wikipedia n1 page...

How improve Speech Quality (EVRC-B)?

Hello,
Does any body know how improve Speech Quality (EVRC-B)? I made some research and I have not found that the application (ProgramMenu.apk) has applied these changes. It just keeps them in internal variable for later display, but really it does not change the value for the baseband firmware.
Best Regards,
Dmitry

##387 then 6 0's then press next twice then hit service option evrc-b then hit back and it should reboot

It is exactly what I am talking about. It is does not work. I checked ProgramMenu application code and I had found that it is does not change vocoder. It is just save value in internal variable. Phone is not rebooted on exit. And after manual reboot the vocoder value restored to default

well it was a shot anways...lol

Confirmed, it goes back to the default EVRC.
However, there are a couple of messages that pop up when you get to the "Field Test Screen" menu, one of which says "Failed to get CDMA RX Diversity" and the other says "Failed to get HDR RX Diversity". Anyone know what these mean?

From stock dialer ##program (using the numbers of course) verify code is 000000, 06test menu, next, next. Changed evrc to evrcB seems to stay until reboot at least. The two RX diversity settings are there also and set to off by default. No idea what they do, would love to know more about this. Suspect if you put them on evrcB might stick, but just guessing. Really only guessing.

It is the same menu as ##387 and actually it is does not work.

I just checked the logs and found out that I was wrong. The program really sends a command to RIL to change a codec. The only problem is that the setting is not saved after restart
