[Q] *#*#4636#*#* - One (M7) Q&A, Help & Troubleshooting

Hi all, the question i'm about to ask has been asked on the internet before but i couldnt find any satisfactory explanation for it. I wanted to change my Preferred Network Type from 3G to 2G as 3G reception is not available where i live , i read on some forums that using 2G only setting can prevent the phone from searching for 3G network intervally which may save some battery. Now, i'm confused about which mode to choose for 2G , i dialed *#*#4636#*#* and went to Phone Information, then clicked on "Preferred Network Type" which, by default, was on WCDMA Preferred, What option should i change it to? GSM Auto or GSM Only? my phone is an unlocked htc M7_U so i cant choose the GSM/WCDMA/LTE Option (it would hog even more battery i think) . Also , can changing this Preferred Network Type have any effect on anything else besides the 2G/3G Network options? i mean, is it safe as long as i change the Network type to the correct option? Any help will be much appreciated. Thanks.

I think gsm only mode.

thanks , can anyone confirm this? also , does changing Preferred Network Type has any effect on anything else besides switching between 2G/3G/4G mode?

should be fine setting to "GSM only", setting it to "LTE/4G only" could make problems, because most carriers don't support calls over LTE (mine would be an example: so if I set to LTE only, I can't make or receive calls, so when it's on auto, it automatically changes to 2G/3G during a call)
You can also just change the setting in:
Settings -> Mobile data -> Network mode -> GSM Only

Force WCDMA Only

Hi all,
Would like to check if anyone knows how could i set "WCDMA Only" (3G Only) on Galaxy S?
I can only Force 2G only via the settings menu, but not 3G only.
Managed to access the "Phone Info" menu via *#*#4636#*#*, selected "WCDMA Only" from the dropdown box.
However, nothing seemed to be set nor i see any button to save the choice?
Anyone happen to know how can i have it set? Or i could manually set it by applying some settings somewhere?
Thanks alot!
you cant force 3g... you would get no signal if you didnt have a 3g connection

*#*#197328640#*#* > debug screen > phone control > network control > band selection
You need to do this after each reboot though as it does not stick.
Is there a way to shortcut this with anycut?

The app Network simplifies the procedure quite a bit. Haven't actually gone into a low signal spot yet to see if it fully works as intended though.

thank you very much..i have been searching this high and low...you save my day..
Thank you so much! This helped me diagnose the SGS and see if I have 1900 3G in my area (1 bar). here's a tip that I used for quick access to the debug screen just as a trial and it actually worked
Enter ONLY *#*#197328640#*# then hit add to contacts (notice there is no * at the end).
Give it a name (Samsung Debug Screen) and tap to edit the number and enter the final * at the end.
Save and exit. Now whenever u want to enter debug mode to change the network or other stuff just type *#*# and it should appear. Tap on the contact and voila!

My operator doesn't have a 2G network... all they have is 3G. There's no point in my phone looking for anything other than a 3G network.
Solution added to FAQ
sorry to ask if this is already answered but how exactly to i get to CONFIRM my wcdma only selection? i check it and nothing happens, data connection stays on "G" symbol. I know for sure that at the place where i tested i get NO 3g signal. which means probably that i should be losing all signal after choosing wcdma only. that does not happen. also if i close the phone info app and reopen it, choice gets back to default (3g/gprs).
any help appreciated... I really need this.
forcing to only 3g is a bad move, i tested it on my n1 and i kept dropping calls once 3g lost signal.

Its available in the new firmware I9000XWJM1
Hey, its there in I9000XWJM1 and tested working great as expected! However its a beta so you may see other issues. Not sure if its there in latest stable.
Just to confirm, i upgraded my firmware to XWJM5 today, and i noticed that in settings > wireless and network > mobile networks, there's a new menu 'network mode' in which there's 3 options - auto / gsm only / wcdma only. Nice touch!
In answer to the cynics, there are times when browsing, when the phone is borderline whether to give you 2g or 3g, it does come in handy, and it's safer too, as if i have to browse on 2g it makes me want to smash the phone up!!

LOL "safer"
@OP Although 'WCDMA only' mode may not be a good idea and hence not recommended but just to confirm
my current Build i9000XXJPH have following three modes
GSM/WCDMA (auto mode)
GSM only
WCDMA only
JM8 build also have this mode. I noticed that when I flash the i9000M (bell version) previously it didn't have these modes.

[Q] Anyone knows how to change HSPA / HSDPA to enable? PLEASE HELP!

hi... my name is Juan and I'm looking for help from chile...
I want to enable HSPA / HSDPA in my samsung galaxy S, because here is very slow our mobile network.
Me and my girlfriend we have the same cellphones, our configs are the same (options, mobile company, acces point names, everything!)
She can "surf" with HSDPA at 1.9mb/s but my phone is always in EDGE and everytime that I make a test with SpeedTest, my speed is 0.07Mb/s!!!!!
I read EVERY PAGE, in the thread: http://forum.xda-developers.com/showthread.php?t=837716
and I was looking more for help here...
I sought on internet and I tried EVERYTHING... but nothing happen...
Please, exist another way to change the HSPA / HSDPA from 0 (disable) to 1 (enable)???
please, help!
thank you!
no one?
any idea? change a variable inside the root folder??? please help.
thanks!
First do you have 3g enabled from your operator?
Secondly make sure your network is not set to gsm only in your handset
Im having this problem also.
Trying to flash CM7 and having issues. I believe the answer is to enable HSDPA.
Has anyone managed to successfully get this working. Im on Orange UK if that helps.
Did you followed this procedure:
Go to the phone dialer pad and enter this code: *#301279#
Click [2] CHANGE HSPA REVISION
Click [1] RELEASE 99 (HSPA OFF)
Then you should see something like:
CHANGE_R99
HSDPA OFF, HSUPA OFF
?
I've exactly the same issue. I have tried the *#301279# code and change it to on, but it just won't. I'm going into "Click [2] CHANGE HSPA REVISION" and selecting the HSDPA to on. But if I go back and check the status it is still 0. Is this has something to do with the carrier? Or maybe after selecting the value you need to save something? Desperate!
I have the same problem. I have hsdpa 0 hsupa 0 and can't turn it on anybody has solution ? I wanted flash cm7 but I can't do it without hspa enabled
Yup same issue here. Was going to create a new thread, but perhaps I should bump this one instead.
*#301279 is permanently ingrained in my head now, but I just can't seem to modify any settings through it.
Suggestions if anyone new has come on board?
if you are all running CM7 I think you need to flash to a 2.2 rom, enable HSPA in that rom and then flash back to CM7. I read that somewhere in the tutorials for previous versions and not sure if this bug still exists but just so you know. good luck

Enable 3g from your operator. Then go to settings > wireless and network > mobile networks > [select] use packet data, set network mode to WCDMA/HSDPA/UMTS.
Should work now.
I have the same problem..
but when i go to settings > wireless and network > mobile networks > [select] use packet data, set network mode to DSM/WCDMA (auto mode)
Where is HSDPA & UMTS ?
anyone can help..
This worked for me.
1. dial *#301279#
2. select 2
3. select 3
4. hit back key to exit.
5. go to Settings->Wireless Networks->Mobile Networks>Network
Mode. Select GSM/WCDMA(Auto Mode) or option 1 whatever that is.
6. hit back key to exit.
7. If still not working toggle airplane mode. This step should not be needed though. If you wait a few seconds you should see the 3g/h/h+ appear.

[Q] FXP314 phone switches between 2G and 3G mode ??

Hello friends,
I recently installed CM11 FXP314 into my Xperia SP smartphone. The ROM is amazingly smooth and responsive to use. But with one problem is that even though I use preferred network type as 3G mode, the phone sometimes switches itself to 2G mode that results pretty slow internet speed. The stock Sony ROMs doesn't have this issue. Is there anything I can do?? Does the developer can fix this issue ???
Thanks in advance

On my CM11 there are basically 3 options under "Preferred network type" LTE, 3G and 2G. Since my phone is an C5302 model (No LTE support) me selected the 3G mode but the phone sometimes switches to 2G of its own, resulting poor internet speed.

[Q] XT1053. Preferred network type question. No 2G/3G ?

Hey Guys!
I'm from Argentina and I have bought (via Amazon) this amazing phone. It is the Developer Edition 32GB, XT1053. I think it runs the T-Mobile rom. I bought it because it is the global GSM version and its LTe bands works down here (same bands as US) well.
So far so good with this little and fast phone, but I was really surprised when i went on to check the preferred network types options, and found I only have 2 options: Automatic or 2G. There is no "3G/2G" option as I use to see in other phones. Normally you would expect 3 options here:
LTE (which includes 3G and 2G also), 3G (which includes 2G also) and just 2G.
Thing is, so far I don't mind this since Its cool to have it automatically, the phone will always try to find LTE and if not, 3G... and if not, 2G. The thing is, Argentina is currently setting up LTE over the country these days (yes, we suck), and in the future the operators 'might' charge an extra cost for using LTE instead of 3G, and that's what worries me... not having the option to limit the phone to 3G/2G was something I wasn't expecting and honestly I don't want to flash the phone to another rom, not at least in the near future.
Anyone knows if this "Automatic - 2G" setting is normal to see in this version ? Do you know if there's some kind of workaround to make it work under 3G/2G only in case I need to avoid LTE in the future for extra fees and so ?
Thanks for your help guys!
Edit: Forgot to mention, the phone came out with 4.4.3 but I upgraded it via OTA to 4.4.4 right away.
Yes the Automatic - 2G option is normal for the xt1053 retail stock. Android has hidden menu that gives more options tho.
Use this app to access hidden menu: https://play.google.com/store/apps/details?id=com.snclabs.radioswitcher&hl=am
Scroll down to where it says set preferred network type and change to whatever you want. gsm only being 2g, wcdma only being 3g, and so on
If the setting doesn't stick after reboot you can try toggling data off then on after changing the setting. try a few times it will stick after reboot.

Thanks man! That app will be really helpful to me if it happens that the operators start charging extra fee for LTE use in the near future.
Btw, I don't understand that much all that names. What would be the options for having 3G and 2G ? Should it be "WCDMA preferred" ? (I guess that takes away LTE) I will not use it under 3G only since I will be without signal if I happen to run into a 2G zone. (yes, we still have a lot of 2G zones in this country )
Thanks!!!!

[Q] Problem with 3G data connection

Hi
With my friend purchased 2 Nexus 6. (I bought it from Netherland and my friend in U.S) In our city we have 3G signal. Most of the time I cant connect to 3G connection and only can use 2G (EDGE) but my friend at same time and same place and same operator connect to 3G!
we have the same build number on our phones.
today I try to solve my issue and got some information about this problem that I’ll explain it. Is there anyone can help me to solve it?
In setting >> More >> Celluar networks >> Prefereed network type when i select LTE a green circle added that show now LTE is selected (picture 1) but when I close this menu and again open it , LTE is not selected (picture 2). I tried more than 10 times in different places, even flash latest nexus 6 factory image and test with my friend sim.
After that I tried with *#*#4636#*#* secret code and went to Phone information saw my preferred network type is : LTE/GSM auto (PRL) , and my friend’s phone is LTE/GSM/CDMA auto (PRL).
I changed my settings to LTE/GSM/CDMA. again when i close this page and reopen it it automatically changed to LTE/GSM. (picture 3)
All of our settings are the same. but just when we dial *#*#4636#*#* and go to phone information >> select top menu >> select radio band we have diffrent datas.
My phone just have USA band but my friend has 3 more option (picture 4)!
I hope someone can help me to solve this terrible problem.
P.S. becuase of poor 3G signal in some areas I can't choice WMCDA Only option
thanks

first off you and your friend have different nexus 6. sounds like your friend has a US version and you have the international version. the difference between the two is the radio/frequencies included.
