HTC Desire - Froyo, No HSDPA - Desire Q&A, Help & Troubleshooting

To be more accurate, nothing but UTMS.
The phone just will not connect to a network. This morning on 2.1 Eclaire,no problems, upgrade from 13:00GMT and then nothing.
I have gone through the following checks:
Settings, Wilress & Networks, Mobile Networks, Network Mode, and ensured that both GSM and WCDMA modes are to auto select. In that menu also ensuring that Enable Always-on Mobile data is ticked.
Using above, i have de-selected the options to use GSM only, and WCDMA only, also interchanging both of these with reboots of the phone. No go.
I have also *#*#4636#*#* , Phone Information, to see what the network was connecting as, also ensured that the phone selection preference is WCDMA preferred.
I have also changed this to be 'only' and rebooted.
I'm out of ideas, and frankly looking to see if anyone has had this problem?
Would appreciate thoughts and advice. Thanks in advance!

Same here!!! HSDPA lost immediately after updating to Froyo
Solved now, turns out APN settings got cleared during the update and needed to be rest ...

yep everytime is this APNs

had the same issue today after the upgrade, all the other settings were kept except for the APN which was a bit strange.

WCDMA / GSM auto problem

Hello Guys,
I'm experiencing a problem with my Froyo Desire for probably a week now.
The thing is that in certain areas my Phone can not receive calls / sms or such. In other words "GSM services" dont work. 3g though works fine (stable, strong and fast connection) My Provider is T-Mobile.
After quite a lot of testing I was able to isolate the error:
When WCDMA / GSM is chosen by the phone automatically it seems to me as if it didnt switch "back" to register with my provider via GSM when i want to make a call or if someone wants to call me.
When i switch to "GSM only" manually everything works fine but i have no 3g of course.
I also experience this problem only in certain areas. I live in an area where there is really strong HSDPA available (up to 7mbit\s). When i go to other places of my city i still get HSDPA (not as strong) but calls / sms still work.
The last paragraph may be of no importance, i don know.. probably it helps..
I have googled quite much about this problem and also found a few persons experiencing the same issue but nobody was able to come up with a solution.
I would be very thankful if someone could try to figure this out.

gsm only Desire?
I'm having a nightmare with 3g 2g connectivity on my Desire on the three network whilst at home. If I could manually select gsm only this would be fine as I could still call and text and use wi-fi. Unfortunately my options are gsm/wcdpa (or whatever) auto or the 3g only.
can someone please advise if it is possible to select gsm only and if so, how?
many thanks
Can someone please advise me how if possible, to set the desire to gsm only?

Wireless and network-Mobile network- should be here somewhere.
Thanks, but there is no option for gsm only. It's wcdma only or gsm/wcdma auto. there has to be a way around this.
Similar problem, different version
I've experienced similar problem.
In some area, I can get steady grps signal when I switched GSM only on; but when I switched WCDMA/GSM on, I could get no data connection at all.
I'm using China Unicom's mobile service.
Solution
Hi there,
I've the same issue and I fix it allowing the option GSM/WCDMA Auto in the configuration menu.
Then enter the following code *#*#4636#*#*, select "phone Information" and set preferred network type, set "GSM car (PRL)".
Sorry about my bad english.

WCDMA doesn't work all of the sudden

Hi,
I've been using my desire for a while now. Today I switched from provider. At first everything worked fine. Then I reported the phone and I didn't had any gsm network. I tried another sim and everything worked. I tried the "defective" sim in an other phone everything worked. I got a new sim from the provider and tried again. Same story, initially it works. I reboot and no connection anymore. Now after some fidling with the settings I found that when I disable wcdma and turn on "only GSM" the phone finds a network (only gprs) and works. If I put it in auto mode, it gives no connection, in wcdma it also gives no connection.
The provider has no idea, HTC support Belgium has no idea. Can somebody help me witter this?

Have you set up your APN settings correctly? Chances are you have not. Also I find my internet connection to have problems when I changed providers and sim cards, however I installed a completely new rom and wiped everything and redid all the APN settings and it works now It still a bit dodge, but I can toggle aeroplane mode on for 10 seconds, then off and it works.

Problem with network mode (ARHD 6.1.1)

hi everyone,
I´m having a problem with my DHD (I´m using ARHD 6.1.1):
In settings > wireless & networks > mobile networks > network mode I´m not able to set only GSM, the button is just not there...
there are only 2 options, WCDMA only & GSM/WCDMA auto
I´m from Austria and have just switched to Three (3) Austria, which has only 3G network by itself. The GSM network is provided by A1. So if I´m somewhere where the 3G connection is not that good, the phone starts jumping between GSM and 3G network, which is really annoying and costs a lot of battery.
I know that there was an option like GSM only, but since the new version came out it just disappeared.
Reflash and Wipe + Flash didn´t worked for me. Radio is the correct version!
Is this a problem with the ROM or with my APN settings? I´ve just tested CM7 and there I´m able change between 2G and 3G with no problems.
Anyone has some ideas? Thanks for help!

changes Rom
!!!!!!!!!!!!!!!!!!!!
i use ardh 3.3 and the same options there

LTE in NYC

Hi guys,
I just bought this phone a couple of weeks ago and i've been trying to get LTE working and I can't. Could you guys guide me to the correct APN for LTE and MMS.
Thanks in advanced.
That's all dependent on the carrier that you are with.
If you find that adding the APN doesn't get you LTE connectivity (but it does get you 3g or 3g+)... maybe try Settings, More, Mobile Networks, Network Mode and see if LTE is selectable there. Or dial *#*#4636#*#* , go to Phone Info, scroll down, and choose an LTE/GSM preferred network type?

Force 4G only.

Is there any way we can force cellular network to be 4G LTE only? I want to stop it from automatically switching to H+.
I'm on stock nougat, rooted.
I think you can change it in the hidden service menu. BUT be VERY CAREFUL not to change other things in there.
First make sure your preferred network type is LTE auto, not 3g or 2g only.
Next, go to phone / dialer app.
Enter: *#*#4636#*#*
It should automatically direct to Testing menu, with Phone information, Usage statistics, and Wi-Fi information choice.
Select "Phone information".
Warning: There's many things to see here, but you can easily ruin your radio band in here. Just follow this guide and do not even touch other things.
Go to "set preferred network type"
I'm not sure what it would show for your phone, but for mine it shows "LTE/UMTS auto (PRL)".
Select "LTE only". It should immediately reset your network to 4G.
If it still switches to 3G, then test other options in the "set preferred network type" option.
After finish, exit the hidden menu and clear it from recent apps menu.
Warning: DO NOT CHANGE OTHER VALUES IN THERE IF YOU DON'T KNOW WHAT YOU'RE DOING. IT COULD RUIN YOUR RADIO BAND IF YOU'RE NOT CAREFUL.
Thanks. It worked.
