[THINK TANK] Turning off 3g allow only edge.

Okay i see on Samsung or ATT for some reason is only allowing 3g connections. When i had my nexus one i was able to use gsm only or gsm auto (prl) etc..
Wondering if anyone successfully been able to change the settings when you dial:
*#*#4636#*#* i believe it is.

Off-topic, but: which clock/weather widget are you using? (sorry! But I love sense and just had to ask!)

could possibly be beautiful widgets
edit - it was fancy widgets

i would love to know where you got your wallpaper

Would love a solution. The standard *##info##** pulls up the admin (or whatever) menu but I access band selection it says access restricted. The menue where you can select WCDMA only or GSM/CDMA auto etc is accessible, but the change doesn't stick. I selected GSM only and then backed out but nothing happened. Killed radio and turn on again. Still on 3G. I tried the *#*#197328640#*#* as well with no luck.
If anyone can figure out how, by any means, lock the phone to GSM or enable manual band selection it would be much appreciated.

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.

This works, Just have to re do every time you reboot

I would also love to find a better solution to the switching- since I am now locked to a non-unlimited data plan!

How-To Disable 3G and keep Edge running

So I've noticed a lot of users wondering how to disable 3G and keep running Edge on their Captivate without killing their data connection. I found out how to do this from another forum and thought I'd share Hopefully AT&T will read their forums and listen to people and create a toggle to do this.
- Type in *#*#197328640#*#* in your phone to get to the "ServiceMode"
- Choose [1]Debug Menu
- Choose [8]PHONE CONTROL
- Choose [4]UE STATE CONTROL
You now have 2 options: CHANGE RAT TO WCDMA or CHANGE RAT TO GSM
If you want just an edge connection (here at work 3G and Edge keep battling to win so I love disabling 3G) then choose the GSM option. To get back to 3G just go back into ServiceMode and go to WCDMA.
Hopefully a dev or someone can make a toggle or widget

An app or a widget would be great to turn off 3G. Is there a way to get tasker to go through these steps?

You can use AnyCut to create a shorcut to the ServiceMode and it makes things much easier.
Since I don't know how to program for Android I wish I could help making a widget but I wouldn't know where to start Until we get a skilled dev to make a widget/toggle either the AnyCut link or manual entering of the code will have to do...
But at least now we know WHERE to disable 3G all other "fixes" haven't worked.

I noticed that once you change it to one of these modes there is no way to get it back to the default "DUAL" mode it begins with if you go to "Current Connection State" menu. Does this force WCDMA or GSM with no way to get it back to auto?

If you turn off your phone and turn it back on, it goes back to DUAL.

There is an app in the market that will bring up the service menu on Samsung phones.

Try this app to get into the service menu

You were able to use anycut to bring up the Service Mode? When I tap the resulting shortcut I get a crash every time...
This is on an i897 Captivate on JH2...

I was thinking of the PhoneInfo where the other tricks had you change a setting to GSM auto. I couldn't get AnyCut working either.
So as far as the dual mode, when you go to WCDMA it will go back to 3G but can still go into Edge mode if you lose 3G.
Think of it as Wireless G band also B compatible in a wireless router

Any way to force LTE only mode?

The thunderbolt had this and it was nice.
Basically when I'm at work I'm in a fringe 4g area. If I leave the phone in 3g/4g auto mode then it constantly switches between the two and it destroys my battery. Not only that but it makes 4g basically unusable for me as it never stays on long enough to do anything with it.
On the thunderbolt by going into the phone info settings you could select LTE only mode.
On the Charge you only have the options of going CDMA only or CDMA/LTE auto. There is no LTE only option.
Is this something that can be corrected by an app or rom or kernel or is it built into the radio software?
I used the phone info app that worked great on the thunderbolt and on the charge it just comes up with a bunch of options like WCDMA only, GSM only and such and as far as I can tell none of them actually do anything.
Hopefully someone knows the answer to this because I like tethering to my tablets at work but if I can't have consistent 4g then I'm gonna be forced to return to my tbolt which is a shame because I like this charge alot better.

I haven't pucked up a Charge yet, but most Sammy phones let you for some fine grain tuning if the radio and other system settings via a menu accessed by a dialer code.
You could try *#*#197328640#*#* (is debug mode) and dig in from there.

Already tried that, it doesn't work on the charge. It just dials and you get the "Welcome to Verizon wireless, your call cannot be completed as dialed" message.

I believe if you go settings ->wireless and network->mobile networks->system selection change it to CDMA mode will disable LTE.

you can try dialing "*#*#4636#*#*" that takes me to a hidden menu on the thunderbolt. If it works, from that menu select "phone Information" then select LTE only. or if you want to disable 4g (Helps battery in non 4g areas) you can select "CDMA auto(prl)"

Thanks but did you guys even read my original post?
For starters, I'm not trying to disable LTE... I'm trying to force LTE only.
Secondly, as I previously said, This phone does not have the same radio options that the thunderbolt does. There is no option for LTE only. I understand the difference between CDMA auto PRL, CDMA/LTE auto and LTE only. THE PROBLEM IS THIS PHONE DOES NOT HAVE AN LTE ONLY OPTION!
I tried the phone info app that works on the thunderbolt, the only options are all for WCDMA only, GSM only and CDMA only and various combinations of them. There is no LTE only. Besides, none of the options present in that menu actually change anything, only the 2 that are built into the wireless network settings do (CDMA only and CDMA/LTE Auto).
Not trying to be a **** but if you're gonna post something to try and answer a question or help someone at least make sure you read the question.

In the same boat as you. I actually get decent service on LTE at home, and virtually nothing on 3G... go figure, but it keeps trying.

i have the same problem as both you guys and this is so frustrating. when its connected to 4g i get between 8-10mb down. i also have a samsung mifi hotspot for verizon and it shows a strong 4g signal and gets over 10mb down consistently in the very same location.
i have no idea why my droid charge keeps switching between 4g and 3g. the funny thing is the only reason i really mind is because the 3g signal is horrible. if i was getting 2mb down on the 3g like i have seen at other locations i wouldnt mind at all.

yeah i have the same issue as well, i'm really not even sure what it's testing to decide to switch from 4g to 3g, i live about 100 yards from the verizon tower i'm connecting to and have full reception on both 4g and 3g but yet it still switches randomly between the 2, we really need a way to disable 3g

Still nothing on this front? I'm afraid I'm gonna have to return my charge tomorrow then =(
No LTE only mode = no 4g for me.

I already did and canceled Verizon, I'll have to stick with sprint. I really loved the charge, and wanted to keep it and stay with Verizon , but my evo gets a full 4g signal both at home and work. Too bad, the charge was an awesome phone
Sent from my SPH-D700 using XDA App

It actually seems to be the way android handles 4G, either on purpose or just coincidentally.
I have the same issue at work with Sprint, 4G gives me 2-3 bars but there is NO 3G, but it turns 4G off when the screen is locked, so it sits there trying to get backups in 3G all day, spare parts lets you force wifi to stay on, surely there should be a similar switch for 4G a dev could find.

Any luck on this issue here? I have a feeling I'm in a fringe area where it could potentially switch me between networks quite often...

Is it safe to assume that an LTE-only option is impossible unless Samsung does something to enable this functionality out of their LTE chip (CMC220)?

Any updates on a LTE/4G only option?

I found out how to force LTE Only ...
Warning! If this bonks up your phone, don't blame me!
Use at your own risk!​
Now that we got that out of the way, here is what I have found:
Enable the Hidden Menu option by entering the following code in your phone dialer: *#22745927
Enter an SPC of: 000000
Select: Hiddenmenu Enable
Select: OK (Your phone may reset after this)
To get to the "Force CMDA/LTE/Global" menu, enter the following code in your phone dialer: **583
If you press the LTE button, you will be fixed on the LTE network.
Reset your phone
Taaa-daa!
Note: You apparently need connectivity to the CDMA network to make phone calls & text messages (Thanks, chaoscentral!) Oh, well ...
To reset back to the normal LTE/CDMA automatic selection mode:
Go to the "Force CMDA/LTE/Global" menu by enter the following code in your phone dialer: **583
Press the CDMA button, which will re-enable your phone to default to the CDMA network.
Reset your phone
When your phone boots back up, go to: Settings >> Wireless & network >> Mobile networks >> System selection >> LTE automatic
Cheers!

just keep in mind LTE only mode means no phone calls or text messages. since those go over CDMA

Ah, I should've guessed they would make the phone code for this hidden menu option "LTE". Now I wish there was a way to only disable EV-DO 3G (leaving CDMA intact for phone calls/texts). Can't have it all I guess...
Thanks for this regardless!

Yep. I tried goofing around with a few different options on the "LTE" theme, but nothing came up.
Then, I realized that I had loaded new ROMs since the last time I had enabled the Hidden Menus option, and figured out that my Hidden Menus were no longer enabled. Once I re-enabled the hidden menus, I tried *#LTE#* (which didn't work), and then **LTE, which did.
BTW, for anyone that has had problems making phone calls after following my original settings, I have updated the post on to how to get back to automatic LTE/CDMA.
Also, has anyone tried that **583 "Global" option yet? Verrrry Interesting!! (But, spooky!)**
Ain't messin' with your phone fun?

No 3g signal

I'm on bamf soab 1.03 and I dont think anyone else is habing this problem but I'm wondering if anyone knows how to fix this issue. When I get 4g signal the phone will use it but won't use 3g. It drops out of 4g and then just stays without data. So basically its only using 4g or else its just not connecting to 3g. There is no data problem in my area because people I live with are getting 3g just fine....any ideas?

Menu > Settings > Wireless & Networks > Radio Info > Change LTE only to CDMA/LTE mode
if you don't have the radio info option there, download LTE toggle from the market and do the last step.

heh. i tried out the new 1.03 and market just kept crashing on me(even after force stopping/clearing data) and uninstalling updates. so i just thought "to hell with it" and switched back over to shiftao3p

No such setting as LTE only. And my phone has always been on LTE/cdma so its not that I already checked that. I'm not a noob user.

do you have EHRPD on under modem settings in ##778? It should be. Past that I sometimes reset if it has issues locking on to one and that will resolve. That's all for my ideas, though I'm still on SOAB 1.02

This is what i was going to suggest. Here's some information that might be helpful. I've found that with the network testing and stuff the past few weeks in my area, sometimes revision a enabled is better, sometimes eHRDP works better. Try switching revision A and see what it does.
Try dialing ##778# on your phone, hit call if you need to.
Choose edit mode
Password is 000000 (six zeros)
Choose modem settings, go down to revision A, and change from e HRDP to "enabled"
Press menu and commit modifications, phone will reboot.
After it settles you may need to go to *#*#4636#*#* and choose phone info then change your preferred network settings to get a solid signal.

I'm running a version of 2.11.605.3, de-bloated and rooted.
I lost 3G on October 21st. I would either get 4G, or nothing. On occassion, I would get 1x. Selecting CDMA only gives me NO data
If I change the REV-A option under the ##778# menu from EHRPD to enabled, the 3G comes back and the toggling between 3G and 4G works fine.
Switch back to EHRPD and 3G goes away. Seems like the problem is with EHRPD. I don't know why all of a sudden it stopped working correctly and I don't have enough tech skills to identify the possible cause.

VZW has had trouble with their Data network the last two weeks, could be a VZW problem. I have not had any 3G problems on my phone and I am running SoaB v1.03 on my phone.

[FIXED] - [Q] [JellyBean] How to switch on 4G?

I recently installed the JellyBean ROM for my A2 and changed few settings in the power manager after which I am unable to get 4G connectivity. I always see Edge in the status bar. I've tried re-trace my steps in the power manager but havent been able to turn on 4G yet.
Any guidance on how I could get my 4G back ?
----- UPDATE ----
I had to flash the same ROM again onto my phone and now its functioning properly. Still don't know the root cause but will report again if I see it happen again.
Thanks

Which JellyBean ROM? Please remember to be very specific as to the conditions surrounding the problem you're having!
I'd first try to go into Settings/ Below Data Usage tap 'More...'/ Mobile Networks
and make sure that 'Use only 2G networks' isn't checked.
Also, which carrier are you on? (I know most are on AT&T, but I'm on Straight Talk so I ask)

Thanks for your reply. I'm on the "MagicMod-Jellybean-Experimental" Atrix ROM on ATT.
The "Always use 2G" is unchecked which means that it should use 4G when available. Which bought me to the next section where I could search for network providers. When I searched for networks, most of the times my phone fails to find ATT in the list of available networks. I do have 4 bars on my phone though. I dont see the network provider name in the status bar so I dont know where it is connected currently.
My current hypothesis is that my phone is unable to connect/register to the ATT network and so I dont get 4G speeds.
Does that make sense?

Yep. I'm aware that a H is 4G. I see an 'E' next to the signal bar. I did have an 'H' right after I installed my ROM but since today I'm only seeing 'E' .
I'll try flashing the CM10 ROM and check if that fixes my issue. If not, I'll copy over an apns-config.xml from an ICS install and replace my current one with that just in case.

Thanks for the tip. I'll try that. Looks like a reflash (of the same ROM) solved the problem for me though. Its back to 'H' for me. I still haven't tried to flash CM10.
