Rooting and Band Selection - Captivate Q&A, Help & Troubleshooting

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!

There is a long dialer code but it is much easier to download the app called SamServMode from the market. That takes you into service mode where you select [1] Debug Screen, then [8] Phone Control, then [4] UE State Control, then [3] Change RAT to GSM. Im not sure if you then have to tap "Change MODE => GSM" or not but I do for good measure. Now no more 3G! This will revert on a reset but with SamServMode, it's so easy to change, it's not a big deal.

Been using this for a while as 3g signals at the office aren't that good. Although I just added the dialer code as a contact.

[Q] Disable LTE

I'm using the ICS leak 213, and the CDMA-only option has disappeared. Any ideas how to disable 4g? I've got access to the programming menu, but there I'm lost.

LTE OnOff in the market, dials into the support menu (or whatever it's called) where you can change the radio. A bit of a pain, but better then having a dead battery 6 hours into your day.
This doesn't work on the Droid 4, the only option is to turn off the radio entirely.

Works for me just fine. It's not a widget, just a short cut. Select the drop down arrow about half the way down to see the different bands.

I'm not real up on the ICS leaks, I am still running GB, but I dl'd "4g toggle" from the market and it works awesome.
Thanks, I didn't see there was a menu there.

Thx for this thread I've been trying to figure out how to disable 4g. I downloaded the 4g toggle but it just links me back to my original choices of global gsm or lte/cdma. Any further ideas?

You need lte onoff as I stated earlier. Motorola has seen fit to remove the option in settngs to run on cdma only. the app I listed takes you into a support menu allowing you to select the bands through a drop down.
Widgets will most likely not work as the setting is in the framework and is not easily changed.

Works perfectly! Many thanks:good:
So I have been playing around with the LTEOnOff and was wondering if there was any information on the different types of radio's we can choose from.
EDIT:Since I poster this I found a neat webpage with a lot of information about the different radio signals.

Why is "Select Network" greyed out even on unlocked phone?

Settings -> More -> Mobile Network -> Select Networks option is greyed out! My carrier wants me to manually select Vodafone 3G instead of Vodafone to get 3G. How do I do this?
why do you care about the name?
the one thats grayed out is the band select.
google market> search > phone info > first menu> set your own band.

it doesnt connect to 3g because there's no 3g network in your area, chose the 2g one or vice versa
Not that simple. Here's what happened: http://forum.xda-developers.com/showthread.php?t=2034540
On phone information there are 2 ways to change things.
1. Set preferred network type. Options are:
WCDMA preferred,GMS only,WCDMA only,GSM auto (PRL),CDMA auto (PRL),CDMA only,EvDo only,GSM/CDMA auto (PRL),LTE/CDMA/EvDo,LTE/GSM/WCDMA,LTE/CDMA/EvDo/GSM/WCDMA(*),LTE only,LTE/WCDMA,Unknown
(*) default
2. Menu -> Select radio band. Options are:
USA Band,Cellular,PCS,2-GMHz IMT2000
DON'T CHANGE THIS ONE!
Yes, I agree (now that I've learned it the hard way!). But the "band select" that souljaboy posted above is for the second option that shouldn't be messed with!

I found the anser for this the other day. You first have to go into Network operators and unckeck Select automatically.

Go to phone settings and you under "SIM Management", default 3g 4g connection, change the SIM preference.

Yes : download activity launcher
https://play.google.com/store/apps/details?id=de.szalkowski.activitylauncher
Then stretch for "hidden", and open the app that go to a phone icon named hidden something.
Then, in the hamburger menu choose the band selection mode, pick the bands you want to lock to, then activate it
go back to "Network mode" from the hamburger menu and pick "band selection mode".
That's all

Mate,thanks but i am on android 9 with note 9 rooted with the last updates and samsung removed that hidden network app with the last updates. I installed it manually as a system app yet it didn't work .I mean the root permissions in the file system not the typical permissions apps ask for camera,contacts etc when installing or launching. Also I heard something called "hns" removed with the updates and that's why it doesn't work if i even install that app manually.

No problem friend thanks a lot for your try.
Will this work for unrooted stock oreo to lock data from switching towers constantly?
I have a N9600 (TGY) device and I tried to manually select bands using instructions from this video:
youtube.com/watch?v=K-DN0q64lRw
I have the latest version of Android 10 available for this device.
I decided I'd rather NOT fiddle with these settings further and reverted everything... Now after a reboot, my device refuses to connect to the network. For example, I cannot make a phone call... Only after going to "Call Settings & Selecting "Automatic", I'm able to make phone calls again.
Any idea how to set everything back to default settings? I don't like the fact that the phone cannot make calls after a reboot as of now ... I'm using this device on AT&T, so what should the default selection be?
Thanks

This app lets you lock 5G/LTE/4G/3G/2G bands on most Samsung phones running the latest One UI updates: https://www.reddit.com/r/samsung/comments/g49ocr/app_samsung_band_selection_app/
After much headache with this issue, I found a method that works where the "Band Selection" menu doesn't work (this method is confirmed working on my Galaxy Note 8). Thanks @fasho:
https://forum.xda-developers.com/t/how-to-lock-lte-band.3681480/#post-74325453
TL;DR: Get org.vndnguyen.phoneinfo (from an apk mirror as it is no longer available on the play store), and then run ServiceMode as root. Follow the linked instructions further to disable unwanted LTE bands.

*#*#4636#*#* menu locked?

Hi all,
Living in an area scarcely covered with 4G, I've always used *#*#4636#*#* menu to set LTE only mode on my two previous phones.
But, apparently, on my P30 Pro this menu is locked by manufacturer. I can't access it and if launched from 3rd party apps, get an error message telling me this functionality is disabled.
Does anyone have any idea if it's possible to unlock this menu?
Thanks in advance

This did show all the settings, but when I tap to select, it selects the one that was set before selection, so doesn't really work
So, what I've found out, is the following - the value 11 (which corresponds to LTE only), doesn't display this option after restart, even when you put "11,9,6,2,1" instead of "9,6,2,1", and the value 12 (which corresponds to LTE/WCDMA) does appear after restart, but doesn't let you select it and falls back to GSM/WCDMA/LTE...
Only possible solution is to leave the field empty or put "-1" and select LTE only, which you can select, but even in this case you can't select LTE/WCDMA.
Thanks for the help!
