I just updated to Android Revolution HD 5.2.3 and Radio_12.54.60.25_26.09.04.11_M2 from an earlier Froyo version of Android Revolution.
Unfortunately, I have now lost the ability to change my Network Mode to GSM only. Previously when I clicked on Network Mode I could choose between two options, GSM only and GSM/WCDMA auto. Now the two options that I have are WCDMA only and GSM/WCDMA auto.
Is this the fault of the new ROM or the new Radio or neither. It's quite annoying as I often have to change to GSM only when network condtions aren't optimal and the phone is wasting battery trying to lock onto a WCDMA signal when there is none.
I realise I can change it via *#*#4267#*#*. However, that's not optimal as it isn't that quick a change between modes.
Cheers for any help.
Most likely the radio.change to another to see if option retwns. If not change rom.

Doh I think it must be the new ROM build. As I tried a few different older radio builds and none gave me the GSM only option.

Someone was telling me that when you take a ROM from a GSM phone (such as Froyo 2.2 from the N1) and port it over to a CDMA device (such as the EVO), the battery life will be terrible.
He says this is because the build is tweaked for GSM and although it will work on a CDMA phone (since Android supports it), it will still actively look for a GSM signal, causing major battery drain. He says that his unlocked GSM Hero has this problem because he has a ROM that was ported over from a CDMA Hero.
Does this make any sense? And if so, will waiting for the official AOSP 2.2 help the situation?
Not a single person can answer my question? Sheesh...
A CDMA radio will need to subsitute the GSM radio in the ROM, otherwise the device would just be useless.
we run into this on the sprint hero porting CM roms from the n1
there is a app in the market called "network" you just download that hit menu, select radio band (then android phone fc's) scroll down to set preferred network type, choose CDMA auto (PRL) and your set.
this must be done at every boot.
one way you can check is settings>about phone>battery use>cell standby if this shows Time without signal 50% then you have that bug.
Awesome. Thanks for the info
I have noticed people managed to change their network mode to GSM only mode??? How do you that?? I only have 2 options: WCMDA and GSM/WCDMA auto?? Is this thing vary due to your courier?? Currently I am with 3 Australia. I wish I have the option to switch only to GSM. From experience, it can save you a lot of battery.
If you don't have the option then you can't pick it. I don't know if that means it's been removed or if it's simply because 3 don't offer a 2G network service (GSM mode). They probably have some 2G sharing but only in spots without 3G so you still have the GSM/WCDMA auto mode.
That's the best I can offer since I know that's how it works with 3 over here in the UK where they have only their 3G network. The firmware likely has GSM mode disabled for that reason but wait for more to back me up or prove me wrong.

I have a feeling it could be the ROM or firmware that comes with it has it disabled the GSM only option. My Desire HD is the UK version. I am not sure if the other Australian version (from Voda or 3) have that options. With my original desire (and also using 3), I have that GSM only option available. So I dont think it's because 3 doesnt offer 2G network.
Get Advanced settings from Market. You can set it to GSM Only in the phone information menu.

Thank you for sharing..yes, it works....but I will try out and see if it does save a lot of battery life.
Type *#*#4636#*#* in the phone dialer to get to testing menu. Under phone info you can set different options that are not otherwise available. No app is required.

Thanks for the info. I have tested both method...both work. But the only problem, how do we set it permanently?? I mean I have noticed every time you reboot the phone, the setting changes?? and I have to set it back to GSM only??
but even if you could technically switch it to gsm, would it actually make a difference? surely if the actual mobile network is pure 3g and no 2g, then switching on the phone wouldn't change a thing? as its not actually possible to use 2g on 3 network?(because they built network from scratch out of 3g is what they always boast about anyway..)
This is strange. I have an unbranded bought sim free HTC sensation here in the UK which Im using on the 3 network and I dont have the option under network to set it to gsm only. This option should be here on an unbranded handset, and its there on my old Desire which was also bought unbranded sim free when Im using that on the 3 network.
Anyone shed any light on this? I know the work arounds mentioned above, but Im more interested in why the option is missing on my handset.
Cheers
PS I know this is the Desire HD thread but its the only topic I could find on this subject so far.
I don't think it matters, just don't even bother with the settings menu for that in the first place. in the Testing menu just set the radio to either GSM Auto (PRL) or GSM Only. GSM gives more talk time.
Hi guys I had to make a thread because I really don't know what's happening.
From stock I updated to the leaked ICS that came out in the spring. This is where I noticed I could not get lte.
I updated to cyanogen 9 and currently on 10.
I noticed that when I try changing networks from wcdma preferred to auto lte gsm it doesn't stick. It goes back to wcdma preferred even in *#*#4636#*#*... ohhh when I first flashed to the leaked ICS I had it set to wcdma preferred.
Why after I flash anything while on wcdma preferred It is unable to change or stick to any network? BTW even if I change it without exiting the screen I still can't get lte. Yes I'm in lte coverage and have the plan.
Please help thanks

Happened to me aswell, the only fix i could find is to go through the unbricking process to restore LTE connectivity, after that i changed my settings in *#*#4636#*#* and i lost LTE again. Only way i know of is to just do the unbricking process and flash whatever ROM you use, and avoid from changing the network settings via *#*#4636#*#*. Besides in cyanogen mod there is an option in the settings app to change networks and use 2g only. Changing network settings in settings app wont cause you to loose LTE once you change it back to the WCDMA/gsm mode in settings app again

I would try doing flashing a new basband/firmware and then doing a factory reset, if that doesnt help, then I would do the unbrick proccess. (takes about an hour)
Hello
I have a problem with my one x, it does not capture well the mobile network, while on another one x and others smartphone that captures very well the network
I gave him a flash with ruu last updated 2.17; May I always the problem
So I wonder if this is just a software problem that I can adjust itself, or it is a hardware problem and that I should return the phone in this case to the dealer
thank you

Some roms and some versions come with the radio configured to WCDMA only, meaning that it will only connect to 3G and HSPDA networks, most phones are set to WCDMA when available and GSM when not, so the phone skips from one to another depending in signal strengh.
in settings go to mobile network, there should be an option there called network mode, see if its set to WCDMA only or GMS/WCDMA Auto.

Thank's
when I put this option in gsm only I have not network at all; but when put it into gsm an dcma I have network but it is unstable, sometimes I have one bar network, sometimes two and sometimes full but it leaves immediately after, and when I called I got a notification for setting the time zone so that it is already set
thank you again
In Viper ROMs notification bar there was a switch for 2G/3G/2G+3G.
I really miss this option in other ROMs, where only 2G/2G+3G is available. In auto mode (2G+3G) my phone often has trouble choosing network which makes the connection very unstable.
Do you have any tips for an app or widget that will let me lock to 3G only?
Thanks.
Try going to Settings - Mobile Networks - change Network Mode to WCDMA only.
Coming from a Sense 3.6 ROM here. Might be different from ROM to ROM.

Sorry forgot to mention, I use AOKP, where there is no such option in the Settings menu. But I recall your solution works in original and Sense ROMs.
type in wcdma into Google play and it should show an app called network, it simply accesses the network settings inside the os and allows you to change to wcdma only (3G). this does need set after every boot though.
