Thanks for the reply , but it is still set internally to WCDMA Prefered , sure it take 3G , but this is not pure 3G Only [ WCDMA Only ]
it seems this setting is blocked by huawei
I use this app to change it [ set preferred network type ] : https://play.google.com/store/apps/details?id=com.ru426.android.lte_settingforgx&hl=en

maaan of course with some app this phone doesn't support LTE it support HSPA
It will never go to 2G unless u loose 3g signal .. don't worry don't be confused about this options .. they are not different and no pure .. it is always same .. when u see H or H+ it means u are using internet network .. when u stop using internet it shows 3G that means H is in stand by .. 3G is like for phoning mode .. once u start using internet or email or only start messing with phone it will auto start H or H+
dont worry it is pure

I have always used that setting in all my phones , this is the first one with that option disabled :crying:
Gonna keep looking for a solution , I'll post if I found something useful , taking a look @ build.prop to add the missing network setting

You can lock to 3g by choosing your providers 3g network manually from the network list.

I did, from my service provider, but when you look inside it is still WCDMA prefered, not WCDMA Only
I get bad speeds with WCDMA prefered

jesus christ man . u wont get better speed when u choose only .. OMG , u have it wrongly imagined, explained.. completely
there is no difference with speed AT ALL if u choose those your options ..
for first ; if u in certain area with highest 3G signal which is WCDMA (H+) u will get those speeds same it doesnt matter if u have preffered or only.. only means it wont auto upgrade or downgrade signal..! It all depends of area which u within .. if u loose that signal your phone starts look for different signal 3g and if even that is not available then your phone will pick 2g ..
I would also like the option for WCDMA only.

I don't want it because of data speeds per se. T-mobile sometimes has EDGE at a higher power than WCDMA, so it can be helpful to lock it to WCDMA.

What definitely not ! EDGE is 2G class no chance it drains more power ! 3G uses obviously higher bandwidth

If you download "Battery monitor widget" (free version), open it, select TESTS, then network, scroll down a bit and you will see a selection box where you have every network option that the phone can offer. I use this on my Galaxy S4 to force the phone to use 2G only (GSM) to save battery as the option was disabled in the normal phone settings. :good:

Thanks Bro , there are several ways to get into Phone info menu , but the problem is: the setting is disabled

Yeah I dont like these crap apps .. itis not good I like to set it manually ..
Obviously you dont agrre that app to switch to 2G .. that is very slow internet..
And thing is I use 3 UK mobile network and they dont broadcast 2G just 3G ..
So if I select 2G only in options I obviously loose signal ..
So I dont mind.. I will have still 3G/WCDMA connected..

I'm not talking about power drain, I'm talking about broadcast power. T-Mobile USA have a very strong 2G network that the phone will sometimes select in lieu of the faster WCDMA network. That's why this setting can be useful, and why it's included in just about every Android based phone.

Exactly, that is my point
I dont care that much about the drain , but I know I will have less if I lock it to wcdma only , cause it will stop searching and switching between networks.
This is my case with my carrier, 3G all the way.

i think its your location, if you use 3G you could connect but if you use 2G you cant, it means your location doesn't have that strong 2G signal compared to your 3G signal. better try it on other places like malls coz they got high 2G signal.

yeah, just choose GSM and no need to change APN. you just need to change your APN when you change Sim Card because every sim got different APN and our phone only views what APN we added on that certain sim hope this helps

Sorry....I hope you mean every provider had different APN.....cos SIM's from same provider do not need new APN...just change if you move to another provider with new SIM.

Hope above helps!!!!

Hi. I am curious about the Network Type in our LGOG, it says GPRS always. What does it mean? And what are the other types? Please check the SS.

Go to Setting / More... / Mobile Networks (in the bottom). And you set Network Mode you hope.
it means that ur phone supports gprs only it doesnt support edge if it does edge will be written in place of gprs..
also if u use 3g or 4g it will automatically change to 3g or 4g..

Okay, thanks for the info. What's the difference in those network types?
the speed of gprs is 56kbps and edge has speed of 236kbps
it means u will get 8KB/second on gprs and 25KB/sec on edge..
when u use mobile data which sign shows above network bar..

Did you get 3G while choosing WCDMA Only?
If Yes,means you have to do it manually everytime you reboot your device.
If No,means you don't have a 3G data plan.
If you reboot your device mean while it will again set to prefered WCDMA so everytime you need to do it manually. Just to remember if you're getting 3G even on prefered WCDMA then leave it as it is. I think it's an issue regarding weak carrier signal.

Its not the build prop. Its how HTC designed the DHD.
The DHD isnt quadband, You can check the specs at gsm arena.
Some countries have thier 3g on a different band, so if you buy a DHD that doesnt scan for 3g on your countries band, you face the same problem.
I have being trying to fix this problem but got stuck along the way. Its very good to see that people also have the same problem. Maybe the devs would try something.

Nope..
Before i can try anything i have to put the device in diag mode which i have being able to, but the problem now is the device isnt showing up properly in QPST(a program for communicating directly to the qualcomm chip).
It detects the open port on windows but its unable to find the phone in the port.
If the phone doesnt show up in the port, changes cannot be done.
So thats the update.
If you have any idea, you could share
WCDMA
goto mobile network under settings, then select network mode, change it to GSM/WCDMA auto if it doesnt work then change it to WCDMA only.
It'll do the trick.
