[Q] Cannot switch to GSM only

Hey guys, since vodafone UK OTA Desire HD from 2.1 to 2.2.1, users cannot switch to GSM only anymore (this option is disappeared from the network mode). I noticed that not only Desire HD, but sumsong's 2.2.1 has the same situation as well.
Voda UK says that this issue would be fixed in the next release (2.3). Its been a loooooong wait and finally we got the leak 2.3 RUU. However, after tried all the custom ROM downloaded from xda, this problem still exist. I found that sumsong fixed the issue in their 2.3 rom already (says voda UK blog).
So.... does any one know which file should I modified to fix the "missing gsm only" problem?
Thank you.

I'm not too sure if there's a fix for this problem (seems to be another case of Network operators being too restrictive over phone functions). As a temporary measure, you could always type *#*#4636#*#* into your dialer (Special Testing Menu).
From there, if you go to Phone Information and scroll down to Set preferred network type, you can change the option from there. I believe by default this is WCDMA preferred, so its just a case of changing this to GSM only
Hope this helps
Thanks Ashley.
I know I can use *#*#4636#*#* to switch the network mode but its very annoying to do so every time. The funny thing is, the gsm mode appears if I put a SIM card from other country's carrier and roam the network via voda AU.
I suppose its a bug because voda claimed that the new galaxy S 2.3.3 rom fixed the issue though

That does seem a very strange bug. Did the SIM card in question that you have problems with come with the phone?
As it seems a compatibility issue between that specific SIM and the phone and I was wondering if its being detected as a 3G SIM? Are you able to achieve 3G connections?
Also, is the Network Type option greyed out in your phone settings, or completely missing?
It's a brand new SIM card and it works fine under old ROM (2.1). When I used the RUU_WWE_1.35, I can switch between the three options and I can still make a phone call when I switched to GSM only mode. 3G network works fine to me as well if I switch my phone to WCDMA only.
After updated to 2.2.1 or 2.2.3, the GSM only option disappeared from the Network mode.Specifically, when I open the Network mode, it only shows WCDMA only and GSM/WCDMA auto. GSM only is not grayed out, its just not shown in the Network mode anymore.
I borrowed my friend's SIM card (which is Vodafone AU as well) and it shows the same problem in my DHD.
Fixed!!
Ok. I know what caused the issue here. The APN setting for Vodafone AU includes MCC:505, MNC:3, which makes my phone cannot chose GSM only mode. I decompile the Phone.apk and modified the arrays.xml file in the values-mcc505-mnc3 folder to add the GSM only mode back.
After I flash my modified Phone.apk back to DHD, I get the GSM only mode back again!!

Hey linus, I was just searching for the same thing...
I'm using Leedroid's GB ROM (2.2.3) and missing the same option. Was fine on FroYo.
Are you able to share or link your phone.apk? I'm so hanging to get this option back as it's saved me a few times when I can't get good 3G coverage. Also reduces battery consumption...
Probably silly question, but is it possible to change the APN settings or something esle to acheive this without changing the apk? I'm just thinking of future ROM releases.
Hey Linus,
As above any chance I could get a copy of the phone.apk. I'm having the same problem too and it's a bit annoying... Cheers
cannot switch to GSM only
Hi there,
Got a SGS2, that I am pretty happy about, BUT
I miss the option saying "GSM only". According to every manual I see, it should be there.
GT-I9100
4.1.2
I9100NELS1
Would your phone.apk work for me as well..?? If, please mail it to me [email protected]
Cheers

may be the access point is wrong,may be you can press "*#*#4636#*#*"to select a proper network mode,and i believe if you flash kdz will give you 3g back,but it is the last way.

May be incompatible frequencies?
F180L is version for LG Telecom which doesnt use WCDMA network.
F180L does supports WCDMA, but as i remember it has some odd frequencies.
And check the APN

I tried this but when I clicked on the "select radio band" option, it gave me an error notice "?unfortunately, the process com.android.phone has stopped". Plz how do I rectify? NB... My device has no connection to any of the carrier networks after upgrade.

Are you able to use 2G atleast? Did you check the APN settings for your carrier?

Yes, I can use 2G. I checked apn settings. When I select WCDMA only, network just goes off. but when GSM or WCDMA Preffered is selected, then only 2G starts.

Hey guys i'm having some problems with my lg g3 d851, since the screen of my beloved lg g2 died after 2 years and a half, my friend gave me his lg g3 to use it as a tablet since the phone doesnt recognize any signal at all, right now is running the stock rom for android marshmallow, everything works fine except for the signal that either always keeps in "no service", i already try to put another sim card on the phone and its showing the same problem, already checked the IMEI on the swappa blacklist and everything is okay, here are a few screenshots, any thoughts on how to solve this problem would be very appreciated thank you!

hi thanks for replying, yeah i already modified the APN settings under mobile networks with the APN of my carrier that is IUSACELL (AT&T México) and is still showing the same problem "no service" or "searching"
I had the same problem, try installing another modem, or send me an pm, I have the same mobile company (right now I'm having some problems with the at&t mexico)
I am having a similar problem with my d851 30g. It isvnot rooted and running stock android 6.0 tmobile rom. I am with movistar (mexico) it will have signal and be on the network and then eject the sim saying invalid then reset. Did factory reset. Movistar sim worked for about an hour and then same thing. Have a s from telcel switched and no problem till this Morning. Did the same thing and restarted. Recognized the sim and all fine. I am new to this and could use a little help. As it is connecting with the other sim and not my movistar sim. Possible software issue or corrupted sim?
Thanks in advance,
Alex miller

Have you tried changing SIM Cards?
What about booting to recovery and performing a factory reset?
