i am a taiwan atrix user,so i guess my atrix is the internal version...
yesterday,i set the gsm/umts band to [usa band]
then,l lost any 3g signal or 2g signal
now it displayed"no signal"on every boot
i think that if i can set the gsm/umts band to other local,i may fix it
but i the test mode,i just got the usa band to choose
i have reflash the rom again,but it doesn't get any better
how can i do???
Contact your carrier to setup the apn, the screen shot is for canada, telus. Make sure that the fields are properly competed.
System settings - more.. (under data) - access points.

"yesterday,i set the gsm/umts band to [usa band]"
Where did you do "this?"
In the hidden phone menu, I assume?

before rooting my phone under network mode I used to have the option to select WCDMA/HSDPA but after rooting it that option has changed to GSM/WCDMA, how to I fix this?
Unroot........
Naaaah, i have always had gsm/wcdma option, but phone is working in hsdpa mode according to speedtest.net. So it seems to be only a name difference.
i have the same problom my phone has no 3g or H signel anymore
try to enter the apn settings manually.
in the UK we always had GSM/WCDMA even if the phone was running in HSDPA, and since most of you root onto the generic UK firmware that is your answer.
Gsm/hspa is probably a operator specific branding. But its total nonsense , gsm/wcdma is the correct wording as wcdma is umts and hspa is a software specific upgrade which is not available on all towers in most networks.
But in order to use it at all WCDMA (umts) needs to be enabled

having messed up my phone yesterday installing themes/playing....i had to reflash, so after it all finnish i now get H signels fine and 3g in the house ..and yes i have rerooted.
So I installed cyanogentazz v8 the other day. I decided to check and make sure my phone was using the right radio band so I did the following:
Dialed *#*#4636#*#* > phone info and radio was set to wcdma. So I switched to cdma auto prl and then menu > select radio band. It forced close as it should. I turned the screen off for while, then I check again and it was set to gsm. I had not restarted the phone it anything like that. I switched back to cdma auto prl and turned the screen off again. A few minutes later it was set to wcdma.
Now my question is could the app toggle 2g be doing this? That's really the only thing I can of that would change the radio band. Any insight would be great.

I just changed the band and hit the back button and rebooted. I didn't do Menu > Change Radio Band. When I dialed back into the settings, it was still at prl cdma auto.
Not sure what wcdma is.. anyone know?
Checked again and it went back to wcdma. Something is changing my radio band...

Yes, Toggle 2G will reset the network type. However, new in version 0.0.8 I added an option to pick which network type to use for 2G and 3G modes. Just open the settings and set 3G to cdma auto prl

Thank you for your answer. And thank you for creating this awesome app. Saves me loads of battery without the hassle of turning data off manually every time I turn my screen off!!

I'm on CELB Froyo 2.1 and since changing my radio band from wcdma preferred (default on rom) to cdma auto (prl)(default on stock), my battery life has been crap!
Can someone explain this?
Thanks.
Hi
I just got Galaxy S2 att but I am in Europe, and since I don't use phone only for calls & sms I wonder if there is an option to permanently set phone to use GSM only?
I know the trick with ...4636... menu, where I can set to use gsm, but when I restart my phone it goes back to umts again.
Is there some hack to open that menu in "mobile networks" or should I use international rom?
I'd find what db it edits when you do that then make init.d script to make that edit every time you boot.

The phone should technically revert to edge. You see the phone by default is set to 3g prefered meaning in these situations in which roaming in another country and the frequency bands do not match or cannot find 3g in the area that in which your phone uses "att". It would in this case revert to a lower spectrum until it finds one your phone uses. So in this case it should be automatically reverting to edge when you hopped off the plane, boat, canoe, whatever.

I have 3g signal but it's love, and i have seen posts that 3g uses more battery, so since i don't use data i want be able to force phone to use gsm only.
I have tried *#*#4636#*#* but it won't switch to gsm, stays at 3g.
I got the same problem, dude. Still find no way...Using UNNAMED 2.2.1...
You can check you wireless setting menu--> Mobile network to see if there is an option for you to choos Use 2G only.

unfortunately there is no option to choose 2g because that menu option is gray, i can't even open it.
i am also using unnamed 2.2.1
Try *#2263# and in menu choose gsm only, then it will use only gsm network. Bu again, when you restart the phone it goes back to umts

Was just curious about network settings. Under the hidden menu my prefered network is set to wcdma prefered. Is this the best setting to use? This will still allow lte network correct? Thats what mine is set to default and if I try to change it it goes back to wcdma automatically. If im thinking correctly wont this automatically pick the fastest network available to me? Including lte? I camebto this conclusion because I do get the 4g symbol when Im in the signal area for lte. Also what kind of speeds is everyone getting with LTE? THANKS for the help! Just want to check and make sure this setting isn't preventing me from getting lte speeds.
The menu setting that you see is to only use one of the the technology's and the bands those the technology's uses to connect to the network (e.g. gsm,wcdma)
BTW. None of the l9s have LTE the l9 2 might

Hello everyone, I think I made a mess...
I have a Le Max 2 X820, I went to the secret menu (*#*#4636#*#*) > phone info > 3 dots menu > select radio band > and i selected "band mode 6". All of this because I had 4G signal issues.
I thought I had solved because the 4G worked perfectly but I just found out that I can not make calls! While I try to call someone it loses the signal and displays a network error.
I tried to reflash the ROM, to flash another ROM with all the wipes, tried to reflash stock modem.zip but nothing! I am desperate! Please help me
EDIT: On the second SIM slot it works, I can make calls
EDIT 2: if I do a manual network search in slot 1 only appears 4G but if I do a network scan on slot 2 appear 4G, 3G and 2G so I can make calls
I did what you did 2 weeks ago on my x829,i think both options band 6 and usa bands just disabled 2g and 3g bands and i can get it to work with qpst or qxdm easily.
