Hi all,
I'm currently experiencing a problem where my Softbank X01ht drops off the cellular network because I live in a low strength area, and takes forever, if at all, to automatically connect back to the network, even if I move into an area where I know the cellular strength is high.
If I manually turn off the phone portion of the hermes, and reconnect, then it happily detects the cellular network and connects. In other words, after disconnecting, it acts as though there is no network in range at all, even though I know there is.
This seems to have started after I upgraded my radio rom to version 1.20 from 1.07. Prior to the upgrade, I know it connected back to the network quite quickly after it dropped out. Has anyone else experienced this with the 1.20 Radio Rom? I currently have the Imate jasjam rom installed on my phone with the 1.04 bootloader.
Unsure if this is related, but the area that I live in has a weak UMTS network, but a relatively decent GPRS network. I'm thinking the phone is getting confused over which network to connect too.
It also seems that if I'm in an area with a pretty strong cellular strength, it doesn't drop out? Would I benefit from downgrading to the 1.16 Radio Rom?
Thanks in advance all.

I can also confirm that things added with that after a soft reset sometime it cant detect network..i have to manualy turn off/on the radio part....generelly it occures if i reset the set just after making a call or just getting disconnected from edge...
the previous 2 radio that i used 1.16 and 1.08 didnt suffer from those probs...
but the main benifit of 1.20 radio that i get is EDGE speed i can pump upto 220Kb (22-24 KB) download speed in flat when connected to pc as wireless modem but with the previous radios i can barely go 160Kb and the speed did uped/down regularly...
and somewhat strange with this 1.20 radio i cant search for network list manually when even i go to manual in network after sometime i get cant read error...but previous radios where ok in that par too...
and the last benifeat that i get with 1.20 is now the SIM STK menu is working.....

Thanks sajib,
Glad I'm not the only one experiencing it. For me, however, it only occurs when it looses connection to the cellular network. After every soft reset so far, it has connected to the cellular network automatically. To me it doesn't seem to even search for the network. That is, after loosing connection, it is resigned to the fact that it can't connect to a network, so doesn't even try, unless I force it too. I think I have seen it connect automatically once or twice, but either way, it takes at least 10-20 minutes, sometimes it never connects, and I force a manual reconnect by turning off the phone and turning it back on. So is this a known problem with the 1.20 Radio Rom?
Try this...
I had the same problem on my TyTn. Took forever to WiFi connect. Then I found this registry setting:
[HKLM\Comm\TIACXWLN1\Params]
"dot11ShortPreambleInvoked"=dword:00000001
Now my WiFi time-to-connect seems much faster.

Hi!
Thanks for the advice, but mine isn't a Wifi problem, but a problem with connecting to the cellular network.
Or do you think that your connecting to the WiFi network and the cellular network are one in the same?
i am using the 1.20 radio as well, but cant say that i have had any of the said problems... i have the cingular 8525 and have used the 2 latest cingular roms, the aku2.3 and 2.6.. but i did have some of the same problems with i used cingulars 1.16 radio

Do you commonly get cellular network disconnects? I find that if I'm moving around the city or driving around in the car, the network connection is maintained, and sometimes will automatically find the network if it does get disconnected. However, it is only when I am home that the phone disconnects and doesn't try to reconnect once it has been disconnected.
Any idea of what might have caused this issue with you with the 1.16 Radio Rom? Possibly something to do with the AKU version? I'm using AKU 2.3.
Thanks,

I too have the original problem but have not upgraded the radio ROM. I have the T-Mobile Vario II (sorry not sure what ROM that is) but often when I move from an area of either very weak or no signal to an area with a signal (coming out of a shielded building) I too get the same problem. Initially the phone shows weak (or even strong) signal strength but when I try to make a call I get the box up on the phone screen telling me it cannot connect. I have found that eventually it will, when left to it's own devices, get itself sorted out and allow a connection. But it is invariably quicker turing off the phone (via comm manager) then back on - this always results in a valid connection.
Perhaps the problem that you describe is not related just to the 1.20 Radio ROM upgrade?

Hi Tony,
It could possibly be an application or the ROM itself causing the problem, however, I think its the radio rom in my case, simply because this problem only started occuring after I upgraded to the 1.20 Radio Rom. Previously on the 1.07 Radio rom, the phone would connect automatically and immediately. Also I just performed a hard reset after I discovered this problem, and it still seems to be occurring...
I also am sure that after a long while the phone reconnects, I have seen it try reconnect a couple of times. But then again, a couple of times I've left it for 10-30 minutes, and it hasn't reconnected. Unsure of exactly how it chooses to reconnect and when it tries to reconnect. You would think it would try reconnect constantly after a specified period, but in my case it seems very random.

i actually get pretty solid coverage whether moving or stationary. especially at home since i live not a quarter mile from a cingular tower and i dont think its necessarily related to the aku version since i have gotten the same result with either 2.3 or 2.6. But i can say for sure that the cingular 1.16 radio is junk my biggest complaint was gsm calls cutting out and on my calls on 3G had a very weird digitized background noise, kinda sounded like a bad digital echo... 1.20 fixed all of that for me

When I'm roaming around my connection always seems to be sustained. e.g, I've been checking my phone ever 1hour for about 24 hours, and have yet to see my signal lost. Is it possible that the phone is getting confused over which band to connect to? As I said in my first post, I have a relatively weak 3G/UMTS signal from my home (1-2 bars), and a relatively strong GPRS signal (3-4 bars). Presumably the phone is UMTS-preferred, and uses GPRS as a secondary.
I saying this, even if I go to another area which usually has 5 bars UMTS signal, I haven't seen the phone immediately connect. This was after about 10-15minutes waiting in that area.

yes, the phone is set to prefer the UMTS bands.. have you tried setting the band manually instead of it letting it autosearch? you can do it in the phone settings menu or use the app listed here: http://forum.xda-developers.com/showthread.php?t=286844
Hi guys,
Can anyone help me... I have bought the TyTN just two days ago and since then I've been struggling with a very bad phone calls quality. I haven't been able to finish properly any single call since all of them are dropped in a middle. It looks like the phone is loosing reception whereas I know for a fact that there is a very strong signal in the location I am.
I've upgraded the software today but the problem still occurs. Do you know if this is a known issue or just this particular phone is broken?

Well seeing as you've upgraded the Radio and seeing as your case is quite extreme ie losing calls completely I think i'd try testing it using GSM only. Some folks have reported that if you are in an area where 3g is around but perhaps not always the strongest signal then the phone will swap around from GSM to UMTS. So you can try:
Start>Settings>Personal>Phone icon>Band
in top drop down box select GSM
in second drop down box select the GSM band for your area (if unknown try each until you get the working one)
IF this makes reception better/constant then you have the swapping bands issue and you can leave GSM selected and turn on UMTS when you are in a stronger 3G area.
If this makes no difference return the settings to auto for the drop down boxes.
If the above fails then have you got a new 3G SIM older cards can give problems.
An application that assists with setting certain bands only is Bandswitch or Commmgrpro - Here's an early version:

Thanks Mike for your reply.
Actually I did play with those settings a little bit but it didn't help. I'll go to the shop where I bought the phone and ask for help. Thanks for your attention.
RG
You know of any apps or way to get a shortcut onto the today screen to quickly switch between 3g and edge? Where I work is good 3g coverage, but where I live is right on the cusp of the connection ... so I find unless I turn off the "auto select" and manually choose GSM, I have dropped call problems. Would be great to be able to do this without having to go to phone settings each time.
Weinson,
Searching for BandSwitch by Daniel Herrero on this forum will reveal just such a tool. BandSwitch sits in your WM5 task tray and has the option to switch to GSM or UTMS or Auto with some time delays (before switching back) build in.

Hi!
I have the handset for few weeks and for couple of days I have a problem at the times to connect to internet. Look like Hero try to send data but there is problem with downlink. Some times when you turn off and on the internet it seemsd to be working at the times ....
I have already updated the software to the newest from T-mobile but still the same problem.
Any ideas ???
Thx
Well i have the same problem with Telus in Canada I thought it was a network problem but now you have me wondering if it is a defect.
same here on T-mobile UK in London... I noticed a reboot solves the problem most of the times... But I am not too sure why it happens in the first place. I noticed it seems to happen in very crowded locations rather than when I am somewhere with not too many people. Every time I install a new radio I hope to see the problem disappear, but it never really does. Quite disappointing... :-( Hope for a fix in the near future though.
I've been getting the same problem.
The HSDPA icon will change to 3G, then the connection will stall completely. I'll have to put the phone into airplane mode and back again to restore it.
T-Mobile tried fobbing me off with my contract didn't allow high speed data, to the next person telling me to just try it in a different post code, they're not aware of any problems, with finally the most recent tech support person telling me T-mobile is aware of a HSDPA and 3G problem that should be fixed in 5 days, please bare with us.
W*nkers.
I definately feel like I've bought a red herring with this phone. Or should have at least got it straight from HTC. I'm reluctant to put a new ROM on there so soon after getting it.
In Canada it seems like it is a network problem. I went out of town about a hour and data worked, came back and it did not work. Phoned and was told it is a network issue and to bear with it they are fixing the problem in a couple days. It seems odd that the same thing is happening in two different across the ocean at the same time though. Who knows if it is the same problem though.
I have the same issue with Orange till this weekend when the phone won't work on 3G at home at all even though it gets a signal. The 3G netwrk is down in my home cell area for a week so I'm stuck on 2G. 2G speeds on some sites are even better than 3G as it doesn't stall on the downlink.
I had this issue but it seems to be OK now. Probably a network issue.
Hi !
It look like the blame is the simcard
Someone suggest something and it give me idea. I have put bit of paper betwen simcard and the thing that hold it and then just a bit on top of it and does seem to have problem. It look like Hero have very sensitive simcard holder
Good luck
All fine here!
I'm in south London, UK and never seem to have a problem with the internet. I'm extremly impressed as on my bus journeys I frequently stream like radio without much problem. I hope things improve.
I'm also in south east london
I get awesome speeds with HSDPA, but not so great with 3G.
I generally stream from last.fm and it pretty much stalls when on 3G. Web-browsing on 3G alone is also not that great for me.
This sounds like it's more a problem with the coverage than the phone though (althoguh it's interesting that a reboot/re-enabling mobile net fixes it).
Couple of things to try:
1 - Download a speed-test and see what speeds you're getting.
2 - Check coverage here: http://www.t-mobile.co.uk/services/coverage/street-check/
im having problems to , i spend half the time on Wifi and only use mobile network if im out and about, but im barely getting 3g and im in heart of england (birmingham)
Hi guys, i know this is a common problem amongst some of us, there are several threads discussing the connection drops but please there must be someone out there who knows something about it.
Basically with HSDPA enabled, the connection will last a random period of time before disconnecting by itself and displaying: cannot connect for an unknown reason.
When HSDPA is turned off, only 3G is used, although this works fine, it is fairly slower.
I am on T-Mobile UK, I have phoned their technical support, we have established it is not the sim card but the phone itself and have tried a variety of steps to solve this, for example receiving band settings for WCDMA, this has not fixed the problem.
I have tried changing the username and password combinations and have tried every combination of every advanced network option. I have used the T-Mobile stock rom 1.43, official HTC ROM 1.66, duttys hg, energyROM, artemis 5.0 and artemis 5.5 (would recommend btw) using MTTY before every flash, and every single different radio combination.
Myself, and many people here would be very grateful for any help posted.
Thanks in advance
Why don't you try Settings > Connections > Advanced network > GPRS tab > change from PAP to CHAP.. and reset... or viceversa.. that helped for me..
Thanks for the post, i've tried all that i've tried all advanced settings, at most they last for a day or so but after a while the connection dropouts seem to worsen
Ok ive just gotten off the phone for the third time with the technical support
basically what they've said is that the hsdpa WILL disconnect because the mobile towers simply can't handle the traffic.
He said in his honest opinion I should disable it because it simply won't work well and there is no fix.
Taking the piss juuuuust a little bit
Mine on t-mobile uk will show H, but usually drop down to 3G. It won't give me an error when it drops down though.
It sounds like its not transferring from H to 3G.
To be honest, i was unaware t-mobile ran HSDPA till I got my HD2 (never showed on my BB).
mine switches between 3G and H too, this happens when the connection is being used (for example loading a web page) when the job is finished (page has finished loading) it turns back to 3G right?
are you saying that your connection never disconnects?
may i ask which radio and rom you are using?
thanks!
For my personal experience, I have for over a month, on versions 1.48, 1.66 by HTC, artemis versions, versions of other French chefs. had no problems,
Login Exchange push 24/24 without any cuts, I solicited the network with opera I passed automatically 3g H, and since February it to completely fall with the problems that everyone encounters (lost connection for several minutes , unable to connect to 3G without hard reset)
to remove the sim chip, I try with another chip of the same operator, another chip from another operator, the problem is still there.
For several days I have also continued a Touch HD, it faces no problems, no problems in connection 24/24.
In short, impossible to challenge any operator, any base station, any sim card.
It is then that the problem come from HD2:
-Software: We all try every combination of rom and radio rom possible.
It is the hardware, maybe the chip integrated into a concern for design, manufacturing concerns on some series, may be dysfunctional due to incompatibilitée between several chips of the phone, short, HTC should look into the problem.

correct, it never disconnects.
It will switch seemlessly between them, when using or not using.
same one it came with. O2 HD2.
ROM 1.43.206.4 (70315) WWE
RADIO 2.04.50.22_2
I've also been struggling with this problem ever since I got my HD2 three weeks ago. However it seems like only a few people experience this.
My case is exactly like cgrec92 described. I'm on a 3.5G network in Denmark (3 Mobile), the phone shows the 3G connection at all times. When things do work and I use Opera/weather/Twitter/email etc, the symbol changes to H and I know the data connection is functioning. I can be using this for a whole hour without any problems.
However, if I put the phone down for a while and then pick it up again to use one of its data services, very often it does not connect to 3.5G (or H) anymore. It will still show the 3G icon on the screen, but there's no data connection. Then I go to Connection Manager and I can see that data connection shows as Off - and after a few seconds it goes back to On by itself That does not mean the problem is solved, as the phone still fails to establish any data connection. What I need to do then is manually turn off data connection and re-enable it again, which makes the 3G symbol immediately change to H. Then everything starts working again - until the next time it stops working...
I contacted the HTC customer service and they said it might be a driver-related issue, recommended a hard reset. I did that and for a few hours I thought it solved the problem, but no, data connection still disconnects by itself.
I spoke to 3 Mobile's technical service and they told me to update my software, which I had already done previously (I'm running stock 1.66 ROM Danish). They also said they never received any such complains about the HD2.
Like cgrec92 I've also played with all kinds of network/band settings, but it did not make any difference.
***
One question: isn't the phone supposed to automatically connect via EDGE when it cannot connect via HSDPA? Because in my case it will only establish data connection via H, never EDGE.
Any advice is greatly appreciated!
My take on this FWIW
It's not the phone!
It's the radio ROM installed.
I live in an an area where T-mobile say I can't get HSDPA.
However, I know that I can. How? Because 3 network uses the same local cell and transmitter as T-mobile and their signal will rip your eyes out!!!!!!!!!
All information obtained from a good friend of mine who works for BT, who, service manage the cells for the networks.
Plus, in this location, the cell traffic is then handled by BTs digiatal backbone which takes it who knows where after that.
So I have a very isolated situation in which I know there is a decent HSDPA signal, but I have had trouble with drop outs on my two previous phones (Nokis 5800 and HTC Touch Diamond 2) and originally on my two T-mobile mobile broadband feeds using Huawei E220 cell network modems.
All fixed when I finally found the right Radio and flashed it on the phones and unlocked and flashed the latest modem firmware.
My broadband connections are always on and never drop out and my HSDPA signal on my HD2 is through the roof!
To further emphasise the point all the equipment is used (when home based) behind solar glass which is notorious for blocking mobile phone signals.
Land on the best one and you will get incresed battery life as well.
Bottom line is try the latest radios (2.08.50.08_02 in my case) and I think you may be surprised at the results.

I have the same problem with the connection dropping. What I did to make it work was to disable HDSPA and putting GPRS to CHAP instead of PAP, and so far I have no problems at all
Thanks for the reply and tips. I also did the same earlier today, except that I did not change PAP to CHAP :O. I was waiting until tomorrow before I posted any results, but I gotta say so far the connection has been stable just like yours.
I also called HTC's customer service in Denmark and the fellow I spoke to was very helpful but he said he has never heard about such problems. He sent me updated network settings via sms, but it did not fix the problem.
I mean, only some users around the world suffer from this problem, right? So what is it that's wrong with our devices? Is it a production fault? If I exchange my phone for a brand new one maybe I won't be unlucky again? When 3 DK finally told you the problem was unfixable, did they mention other users with the same issue? Did they ever offer to replace your phone?

Erm!
It's your radio!
But, I think I did say that in a previous post.
You had a helpful fellow who sent you updated settings?
And he thought that was going to fix your problem?
That was helpful!
It's your radio!
The technicalities are beyond a customer assistant at the end of a phone. They work from a script.
I'll send you the settings.
Have you done this?
Have you done that ?
Never heard of anyone else with your problem!
It's your radio!
T-mobile uses PAP protocol (at least they do here in the UK) and it's a handshake protocol so changing that won't really do anything to the signal definition.
You have it or you don't.
It's your radio!
There is no "production fault".
You are not "lucky" or "unlucky".
You are in an area where you will suffer from this because of the ???????
THE RADIO!
I think I have made my point.
If it turns out that you don't have a radio issue then please feel free to admonish me.
Until then----------
It's your radio!
well I don't mean to sound rude but do you SERIOUSLY think we haven't tried that? ive tried every possible radio available here and every different rom, so excuse us for trying new things.im glad your not having any troubles yourself because it is really annoying
perhaps you could post us your rom and radio?
I don't suppose you could post us your settings in advanced network?
did you use the connection setup?
thanks for your help
Yes, I was about to mention something similar. I haven't tried combining different ROMS & Radios myself, but I know people like cgrec92 who have with no good results.
And if it is the radio, then every 3 Denmark user like me would be experiencing the same problem, correct? I don't think that's the case. Actually when you read the forums you will find users from different countries with this problem, and they/we are not the only ones with a certain combination of ROM/Radio.
So yes, by disabling HDSPA I finally managed to have a stable data connection (but no 3.5G, obviously). At this point no one seems to know the cause of this issue, but I suppose it's naive to expect a future ROM to solve it, after all it's not a widespread problem. Is HTC even working on it? Are we sure it's not our devices that are faulty?
I honestly have no idea, but I cannot just accept this problem and live with it after all the money I put into this phone. That's why I brought up the possibility of having it exchanged for a brand new one in hopes that it will not have this problem.
Any ideas?

I referred to my radio in my previous post -20.08.50.08_02.
My OS ROM is Leo Lite 3.
Connection setup used and no further settings.
My explanation for this is the fringe nature of the received signal.
The radio its constantly 'hunting' for a signal and the radio software has difficulty in locking on.
BTW OS ROM and settings ready don't affect the efficiency of the radio signal.

I'll pm you my t-mobile settings.
And I cant use the connection setup, being an O2 HD2, it only allows selection of O2.

I appreciate the help, but he doesn't seem to understand the issue here. It's not that we have low connection, or that we cannot connect to the 3.5G network. The problem is that the phone's data connection will automatically disconnect even when we are in an area with full 3.5G signal. The phone will connect for a while and then, moments later, in the same spot and with full signal, data connection is terminated. So I just can't see how the radio has anything to do with that, especially when there are hundreds of other users out there with the same ROM & Radio as us and in the same network. And yet they do not experience this problem.
Ive have similar issues but it depends where i am it appears that some towers its ok where others its not!

The radio differentiates between all the different levels and types of signal and it depends on how exact it interprets the signal. They are supposedly optimized before release and then re optimized with each newly released version. Network operators then have their own network parameters and again the radio has to accommodate this as well. One radio will never satisfy all these criteria and some of you will be in the wrong place at the wrong time on the wrong network with the least effective radio.
I can assure you that I most certainly do understand the problem and that is why, in my own case, I have resolved it.
Bit of an odd one. Basically at home with the phone on my home network T-Mobile I simply can't get a GPS fix. This problem has only happened in the last couple of weeks previously its been fine, a fix within seconds.
As some of you may know T-Mobile and Orange in the UK have now enabled roaming between the 2 networks. If I force the phone to roam onto Orange I get a GPS fix with-in a minute. Switch the network back to T-Mobile back to no fix.
If I'm in a different area, network on T-Mobile, fix within seconds. I thought maybe it's quick GPS wrongly loading the wrong area because of an issue in the cell db, I've set quick GPS to never update and now the GPS appears to cold start although quick GPS still says the data it has is valid for x number of days.
I've tried defaulting the phone but exactly the same with defaults and using GPS Test rather than TomTom.
Does anyone have any ideas? Is anyone else having the same issue?
I just tried another test. I roamed onto Orange and got a GPS fix in TomTom, I then set my network back to T-Mobile and the GPS fix was lost! As I switched networks I left TomTom running in the background.
A bit more testing. If I force the phone onto 3G T-Mobile the GPS works fine. My theory is what ever frequency the cell here operates on (some 5 miles away in the 1800MHz band) must be causing the some issue with the hardware
I'm thinking that most people wouldn't be able to experiment to see this, I'm just lucky or unlucky depending on how you look at it that I'm in a position where I can switch networks therefore changing frequency within the 1800MHz band and I can stay in the same place to test it. I've had in the past where the GPS would loose its fix for no reason and then just come back while travelling on a motorway I wonder if this was the same thing. Also the chances of someone owning a HD2 using the GPS and being on a cell who's frequency causes a problem is pretty small, and if your travelling you're likely to just think it's dropped for some reason, and oh yes it's back again now so think no more of it.
You are getting confused between GPS and GPRS.
GPS is the satellite system that you use to pinpoint your location (as with TomTom). If your phone is indoors or has a restricted view of the sky, then it cannot receive a signal.
GPRS is a data connection between your phone and the telecoms company. It is basically 2.5G, which way a intermediate step before 3G became set up.

No, completely understand the difference between GPRS and GPS
I've proven with out a doubt that when using the t-mobile cell serving our house (2g) there is no GPS signal. Use another network still 1800 and there is GPS, use 3g, or move to another area on t-mobile there is GPS.
GPS was working at home while on t-mobile upto a couple of weeks ago, I can only think that the cell has had some work done and has changed frequency.

Silly question, but have you got AGPS activated? Because it can give you a rough location based upon the local cell transmitter info and any GPS satelite signals you may be recieving.

I have AGPS disabled. I doubt my operator supports it. I have tried with QuickGPS disabled and enabled but makes no difference.
If I get a fix while on Orange, leave which ever GPS enabled application I have running, running in the background, force the phone back onto my home network (TMobile), go back to the GPS application there's no fix and no satellite signal being received not even a hint.
I've also tried with the SIM card removed and GPS performs perfectly!
Thank you, I thought I was going mad - my GPS has been working perfectly since I got the phone 6 months ago but in the last week has been dropping out or refusing to start at all.
I tried a hard reset, which fixed the problem until I started driving the next day - after a few minutes TomTom lost it's way. Using a bluetooth GPS proved the signal was good, so I was coming around to the idea that the phone was broken...
I have also now read other users that have had GPS problems when roaming, although usually when switching between countries.
Looking on the T-Mobile website about the orange roaming issue it say 'there might be a few quirky side-effects' but I haven't even signed up for the Orange roaming option, sounds like T-Mobile has changed something for everyone?
I have read that fixing the network choice to manual, not auto, can help with GPS issues while roaming - I've yet to test this.

I've had the issue for a couple of weeks I would say. Certainly last weekend I couldn't get a fix for ages when I set off and it wasn't until I was a way away from home that the GPS got a fix. This was before the roaming got switch on, of course it doesn't mean they were not doing something with the cell/network.
I too can get a perfect fix with external GPS or with a GPS nav system, or by changing networks! I've also tried another SIM card in the phone, again T-Mobile and get the same results.
I've attached some screen shots.
1st T-mobile no satellites, you'll notice that there isn't so much of hint of signal.
2nd Changing network.
3rd T-Mobile Orange and GPS fix.
All screen shots were taken with the phone in the same place.
Just come back from a drive just to test the GPS. Basically driven 30 miles away from home fixing the phone to T-Mobile and 2G and the only time I got a GPS fix was when the phone lost signal.
Parked in a layby and switched over to orange and got a fix with in a few seconds! Just can't figure out what the connection with being on T-mobile 2g is!
What Radio version is your phone using?

Have the same issue with various official T-Mobile ROMs.
I had a play with updating my AGPS settings last night using the Google settings from this thread: http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=544421 when working on Orange couldn't notice any difference, with T-Mobile still not GPS fix.
I left the GPS running over night on T-Mobile, admittedly indoors but somewhere I know I get a fix, there was still no fix 7 hours later.
I live in a rural village covered only by one cell mast. GPS starts and runs fine at home with or without the phone turned on. if I walk over the other side of the hill, different cell mast, the GPS drops out immediately - I can't test if 3G fixes the problem as it doesn't work here. Once the GPS has stopped I can't get it to start again, even switching the phone off to airplane mode doesn't help. Only a soft reset, with the phone still in airplane mode will allow the GPS to start.
Switching the phone back on and the GPS drops, however walking back over the hill to home - back to my original cell mast and the GPS starts again.
I'm pretty sure t-mobile have rolled out a change to their 2G system, but not to all masts? rural ones maybe last done hence why my home cell still works.
How to proceed from here? T-Mobile are kind of hard to talk to.....
One thing I did notice was in Memory Map the satellite view normally flicks across satellite numbers until it finds a signal, if the T-Mobile problem occurs this process stops and it would appear to have frozen the service?
I take back the hard to talk to part of my last post, I emailed support from the website and they phoned me back within 2 hours!
As to be expected they couldn't give any instant answers but I gave this thread as a reference and the problem is to be escalated.
The call centerthen phoned me back and asked if I was happy, also to offer me 30 minutes free calls for next 3 months - very nice thank you.
Good work boomboomer. Hopefully T-mobile will find something. I'd like to know what they find, still can't understand the connection between a GSM network and GPS though. I haven't tried a controlled test with flight mode but will try that later. Out of interest what part of the country are you in? maybe it's just a pocket of cells that are affective? I'm in the BA8 postcode area.
The problem certainly only affects 2G, 3G is fine.
I'm out of the country this week but fingers crossed T-Mobile will find the problem. It's nice to know I'm not the only one with a problem.
I'm quite a distance away, DT2 here.
I've been asked to test the GPS over the next few days and keep a log of when and where it doesn't work, they said their network people will ring me soon.
At least this fault is 'interesting' in the words of their technical support guy, he'd never heard of anything like it, so there's hope they will give it some time.
On the plus side they've also given me a free month of internet, so I can't fault their customer support focus.
Incidentally, do you have SPB shell installed? This was the only change I'd made on my phone at the time this problem started.

I didn't get chance to do any testing today at Heathrow as ended up being a bit rushed. I wouldn't say your not a million miles away. 22miles ish, the Cell that covers our home is in Dorset which is pretty useless when you have to call 999 because you get connected to Dorset who then can't pass you to Somerset and you end up being in a situation where you have no way of contacting Somerset 999 not great in this day and age! But I'm not going to get started on that one on this topic.
It's quite possible its a regional problem.
No I haven't installed SPB shell, I have tried it with a defaulted phone but still had the same problem.
I'm out the country now until Friday, but will do some testing when I return on my return journey. I'll fix the phone to 2g T-mobile and keep an eye on where the GPS drops out.
Oh dear, just got a call from T-Mobile technical networks - they don't support GPS as part of their service and won't be spending any time on the problem, case closed. They did say the problem seems to be with HTC devices only, blackberrys are not effected so it sounds like they have heard of the issue eleswhere?
Looks like it's a network switch required to solve the problem, shame that as I've been with T-Mobile for over 7 years.

Hmm, T-Mobile sold me the phone for use on their network, the phone is sold with a GPS, that now doesn't work on their network surely they need to spend sometime working with HTC to resolve the problem.
I do have a case open with HTC under the ref 10gbc410001235 they were supposed to be taking it up with tier 2 but as yet I've not heard anything back. I'll have to follow it up when I'm back in the UK. It might be worth you also logging a fault with HTC quoting my ref. at least if 2 people call in with the same problem they may start to think it's not just one crazy with the issue!
My other half has a HTC Desire, I haven't checked the GPS on her phone. Not sure if they use the same chipset, of course one is WM the other android. I wonder if its a problem for all HTC phones or just the HD2?
