This been mention many times. If you're coming from another ROM you'll need to do a complete wipe before flashing CM.

Even when doing a nandroid restore from one rom to another?
[Nexus One Q&A, Help & Troubleshooting] prettyboy85712:
Yes. It's always recommended.

Hi,

I am developing a J2ME application on HD2. Basically the application will sent the GPS coordinates received to the java servlet hosted on the server. I am using Netbeans 6.8 and GlassFish V3 as server. But apparently i am getting a java.io.IOException: Invalid chunk header on the server side. I am not sure why this error would occur as everything works fine on other platform for example Nokia N97.

Could the problem be the OS as HD2 uses Window Mobile 6.5 while N97 uses Symbian?? Or could it be the JBlend which causing the problem as HD2 uses that to run J2ME application??

Any guidance will be greatly appreciated. Thanks alot in advance.

Held out for the desire, as i was informed by orange that it was a UMA handset and would be the answer to all my signal problems at home...

Only to find, i am left floundering in the no signal land still with no UMA!

Any suggestions????
[Desire General] SGTDavePwnage:
Post in the correct forum maybe?
[Desire General] crystal_clear:
i would class adding UMA

As a major forward development, and would welcome a patch or external software...
[Desire General] SGTDavePwnage:
We have not rooted the device yet so cant really do much.

The only things you could do would be to install a different ROM, but this will void your warranty
[Desire General] slaming:
well if orange promised it would be uma you are perfectly with in your rights to take it back and surely ask for a full refund for mis leading claims
[Desire General] ninjakettle:
So i've had the HTC Desire for a week now and i'm starting to think there's either an issue with the phone or with the T-mobile (UK) network.

When the phone shows 'H' , browsing the net, downloading, or using the marketplace is a snap.

However, when this dips to 3G, either no data seems to be relayed to the phone or it does so incredibly slowly.

This means, web pages or marketplace often ask me to retry as no data connection is available.

I don't think it's a signal strength issue as i have 3bars when connecting under 3G.

Has anyone else experienced this?

*(worth noting that i got the latest OTA update pushed out today , and still have the issue)

*(Posted this in the UK tmobile forum too, to see if tmob have anything to say)
[Desire General] choccy31:
It is the Network.

Hero / G2 owners have had lot's of issues and last week I was in Europe with my Desire and I had 100% perfect connection 99% on H Speed (even on the underground!)

Came back here and 3G simply does not work anywhere near as good or actually at all!

H or G2 only it seems.

T-Mobile Customer Service feel that not having 3G is fine and acceptable as you are not paying for 3G and they are meeting their requirements of providing the ability to make calls, send text's and have net acces via 2G.
[Desire General] ninjakettle:
- cheers for that info. I've actually seen the issues with the G2 (hero) you mention on the Tmob forums. Can't believe so many users are being ignored.

Just disgraceful. I wish i knew this before signing up with them. I can't get H in my office, only 3G and it's useless :(
[Desire General] assimilator:
Is this network issue location specific, or does it affect of the UK? Presumably London or another major city shouldn't have this issue.

[Desire General] mklass:
Calll TM up I had a new QOS policy applied to my account and also I was told the MMS settings were affecting my speed.. I used speedtest.net app to see what speed I had no more than 300k on both 3G and HSPDA.. It is now fluctuating between 1500k and 2300k :)

They are still looking in to my issue thats why it keeps fluctuating..

Defo worth giving them a call
[Desire General] Erniemac:
any updates ninjak?

i was VERY tempted to get T-mobile deal on this but now im not so certain...
[Desire General] zMastaa:
Hmmm, my connection has been perfect no connection drops...ironic my BT line has gone fault (pretty much dead) and im using my Desire to tether internet on t-mobiles network till they come fix my landline on monday...so yeah no problems here

Having the same issues on T-Mobile Netherlands lately. It already started with my G2. But with the Desire I constantly need to retry... Let's hope we don't have faulty handsets...
[Desire General] friedgoldmole:
I don't seem to have any problems downloading when I have the 3g or H symbol, but occasionally those symbols disappear altogether suggesting the mobile network option is turned off, but its not and it still shows 3/4 bars suggesting it has a signal. I had to reset my phone this afternoon so I could actually use data, bit annoying really.

Can anyone confirm what actually happens when you lose connection to the net via 3G?

My browser has "hung" a few times - page will stop loading, and neither a refresh choosing a link from bookmarks will work. In fact this stops my browsing completely - even using Advance Task Killer to kill the browser doesn't solve the problem, and I have to reboot the phone.

Are these the symptoms people are seeing here, or something else? I didnt notice at the time whether I had the 3G symbok, or the H.
[Desire General] dreamdealer:
T-Mobile is really bad network i was stuck with them for 18 months on my G1 poor mobile internet and phone signal, once i download some app for it, which tells you with a noise when you loose your signal. omg had to uninstall the app becasue it went off so many times. Now on vodafone with my HTC Desire much better in the warrington (in middle of manchester and liverpool) area. A while back my dad said T-Mobile used to be that bad he had to go into the garden to make a call..
[Desire General] brummiesteven:
There seems to be something wrong with the settings IMO.

HSDPA is nowhere near as fast as it should be I don't think. There was a topic saying if you change the APN you get faster internet but I didn't try it.
[Desire General] setspeed:
Does anyone have the TMobile handset, but flashed a generic ROM?

Does this problem still exist with the generic ROM?

I want to stay with TMobile as the prices are easily better than anyone else, but NOT if this internet/data problem persists. I would rather pay the extra £100 to Vodafone over the course of 18mths to get solid data connection.

I will be rooting my phone when the method is made public/reliable etc, so want to know if this problem goes away.

Very interesting - yes, i'm going to call tomorrow and see what they say. Is QOS a term they're going to be familiar with? So if i say - "have i got the latest QOS applied to my account?" they should know what that means - (cos i don't to be honest)

The thing is, you only have to read the tmob uk forums to discover that it may be a network issue. There are a host of G2 owners with the same problems i have.

Will update you guys when i ring Monday.
[Desire General] kasonne:
QOS is "Quality of Service" and its something that gets applied to your data traffic so to kind of control it. Everyone I would have throught would be on a default QOS unless otherwise requested/known to you.

Whether or not they know what you mean and speak to them probably depends on who you end up speaking to.
[Desire General] chiefmcbeef:
I've been on Tmobile coming up to a year now first with a generic simfree Nokia N97 and now a simfree/generic HTC Desire.

I've found that T-Mobile allowed me a max of around 280-300Kb/s download speed when running the mobile speed test at dslreports.com with the N97. Having done some searching online, it seemed that T-Mobile intentionally limit the 3G speed on the standard Web booster/webnwalk package (either £5 or £7.50 depending on when you take it out), so I forked out for the Mobile Broadband booster for another £4.25+vat a month which I could cancel at any time, this was on top of my mobile web/web n walk add on.

This gave me around 2-3.6 Mb/s download speeds which was more like it.

Connection handling on the N97 seemed to be good, I never noticed problems in software when the conenction switched from HSDPA to 3G or back to GPRS, the page would just take a little longer to load.

On the Desire, I've noticed that it doesnt seem to bother switching and just tells you the page can't be loaded. Either that or the apps aren't set up to handle protocol transition. I've had times when apps have been caught in between, Internet browser, Maps and Gmail for example, and think there's no network connection and display an error accordingly, wheras the N97 must have been attempting to connect the apps during the transition between HSDPA/3G/GPRS.

The N97 isn't a decent phone by any stretch but it seemed to handle data connections well :)
[Desire General] setspeed:
This post is completely random, but I thought I'd throw it out there for people...

Apparently there is a similar problem with Android on the "3" network.

And an app to fix it: http://www.appbrain.com/app/uk.co.neilandtheresa.FixThree

I know this is wishful thinking, but can anyone describe what the "network interface mtu" mentioned in the app description is? And whether it could be a cause for our problem?
[Desire General] madmossy:
Had trouble with 3G/HS connections myself, i just wasnt getting them, did a factory reset of the phone (volume button/power method) and it seems fine now, im getting consistant connections with 3G and good speeds.
[Desire General] brummiesteven:
I wanna benefit from extra coverage and things like Orange Wednesdays but I DONT want Orange's awful prices and over branding of phones.
[Desire General] friedgoldmole:
I have little to no signal in my room and so use WiFi a lot. When I leave the house my desire refuses to connect to the mobile data, the h/3g/gsm symbols never show up though I can make and receive calls.

I try disabling/enabling mobile data, selecting my operator (t-mobile) again from the settings. nothing works so everyday I go to work I have to turn my phone off and on again to get mobile data. its not a network problem in my case as my g1 is fine with the same sim.

its getting annoying, I guess i'll have to sent HTC yet another mail.

[Desire General] ninjakettle:
Ok, so I'm back in the office today where the problem seems most prevalent. And I've been doing a little testing. I downloaded the Speedtest.net app from the store, and have been running some tests.

I'm actually happy to see today that data seems to be transmitting on 3G. And i've had no time out errors etc as per last week.

However, as someone has already mentioned. It's constantly fluctuating between 3G and H. I have 3 bars of reception regardless of which of those sync speeds I'm connected at. Should it be fluctuating like this? Shouldn't it just stay on H if available.

Anyway, after plenty of speedtests, i seem to average the following

Download / Upload (kbps)

(3G) = 200 / 300

(H) = 1200 / 450

Seems weird to me that 3G download is less than the upload. What are the theoretical speeds i should be getting in central london for 3G?
[Desire General] friedgoldmole:
Mine seems to flick between 3G/H and even G sometimes when I'm in the office. Though to be fair my G1 used to flick between 3G and G so could be the signal is not that steady in my office. I never got the H icon on my G1 so I assume it showed 3G whether it was on 3G or 3.5G
[Desire General] scotch whisky:
Hi,

I have a T-mobile Desire and am on the T-mobile network. I haven't experienced any of the problems reported here but I haven't been using the device enough to be absolutely certain.

I have however flashed my phone with the generic ROM which may or may not be relevant.

As an aside I couldn't get MMS to work with the T-mobile ROM but it's fine with the generic ROM. This indicates to me that there may be differences between the two ROMs.

I have used all the UK networks and have found T-mobile to be not only the cheapest but the best. Gererally I have found poor performance to be a location problem rather than anything else. I live in Folkestone. Kent. It's just wrong to say that T-mobile is a poor network overall.
[Desire General] ninjakettle:
Ok, have done some more experimenting. I'm really starting to think that the problem only seems to exhibit itself in the browser and the marketplace.

As per my previous post - using speedtest app, i could get a connection under 3g. However, when i try to load a webpage or search for an app, and the sync is showing 3G - it always fails.

The marketplace gives the error - "a network error has occured, retry or cancel....etc"

And the browser times out. If however it flicks over to (H) while doing the same - it works fine.

odd...
[Desire General] ninjakettle:
would appreciate if a few London T-mob users could trying the following on their desire.

1. Ensure phone is showing as connected under (3G)

2. Open Marketplace and click on 'Downloads' - this forces a data connection to refresh your apps.

3. Keeping an eye that the phone stays connected under (3G) - do you get an error?

For me, I get an error. If the phone flicks to (H) it will work.

Also, if i download something from the store (just tried Podkast) - progress bar only advances under (H) and not (3G) - it flicks between the two.
[Desire General] scotch whisky:
Mine most certainly does not exhibit this problem. If I were you I would be inclined to do a factory reset and not load any additional software or make any changes until you are sure the problem still exists. Bit of a pain I know but it could be anything screwing the system up, doesn't necessarily have to be T-mobile!

Edit: I live in Folkestone and don't get the error.
[Desire General] choccy31:
Ok,

I've asked my friend over weekend to check his 3g connection on T-Mobile with Sony W995 and I also have checked my GF who has same phone.

I can confirm that neither will work on 3G but look to punch over to HDSPA only or back to the 2G option.

3G does not work and this clearly is a network issue.

People who say they have no issue with this, I feel do not understand the problem. They look at the 3g sign and assume it works.
[Desire General] sh500:
When the phone is on the Home page it shows the 3G icon but almost as soon as I load up the Market it switches to H. I dont recall ever seeing a connection error though, perhaps been lucky.

EDIT: This also seems to be case when loading up the browser.

PS: Location is London.
[Desire General] HoneyBeFly:
I agree, when it shows the H sign, it will work (on browsing, downloading etc) but if it only shows 3G, it can't.
[Desire General] __WiZaRD__:
So how serious is this problem guys? Is it a Location driven problem?

If so does anyone have any experience with the T-mobile network in Birmingham?

Still trying to decide if T-mobile is the right network to get...

Cheers.
[Desire General] brummiesteven:
I get around the same speeds and this is what bothers me. Isn't HDSPA supposed to be in the megs ie 3mb, I'm sure vodafone even advertise 7.2mb download speeds. So why so low on the desire?
[Desire General] nprussell:
I can also confirm this is a network related issue.

I have just moved from a Hero on T-Mobile UK to a Desire.

2G & HSPDA are perfect. 3G is useless.

That's nationwide btw. I travel a lot with work, and wherever I go in the UK, 3G is ****e.
[Desire General] choccy31:
Well the problem is, T-Mobile deny there is a problem. However T-Mobile also acknowledges there is a problem.

The good guys at T-Mob (Stef , Miles and the forum / twitter side) seem to be updating us on what is happening, although unfortunately not much is happening at the moment apart from just testing and investigating possible causes.

T-Mob won't publically say there is a problem and are hiding behind the "we are meeting our obligations by providing you with a service that lets you make calls, text and use the net".

They say they do not have to provide faster speeds within their conditions and this is an added bonus.

The fact they charge customers to obtain faster speeds seems to be beyond their limited standard call sheet pages.

Hopefully the good guys will keep working on it.
[Desire General] brummiesteven:
I am in birmingham and it's pretty much fine for me, flicks between 3G and H a lot but it's just the speed bothering me.
[Desire General] madmossy:
After a factory reset the other day, I am now getting 3G and H connections but they drop in out of 3G/2G so often that it is draining my battery.

Today having fully charged the phone this morning to 100% at 8am, my battery is now down to 35% after 1 short phone call and ~20mb of data, ~15 mins of in use time the rest was all idle.

The constant switching of networks is a bigger issue than the poor 3G connection, even though when it is connected my signal strength is good (2-4 bars ~ 55-75 dBm)
[Desire General] SousukeUK:
Same Problem on my Touch HD?

ok here is the thing I'm not too sure if my one counts or not as I didn't rad the whole thing.

I know for sure data don't work on 3G as my HTC Touch HD have to switch to HSDPA to even get the weather update. but then it switches back to 3G again.

But the main problem start when I'm browsing the net. As 3G or HSDPA or dropping the signal from HSDPA to no connection switch all the time makes it a bit frustrating.

Also when ever it loses HSDPA the page doesn't load anymore. and it goes through a cycle of 2G then 3G then HSDPA which make the whole process of mobile browsing very much slower.

And I can see the same pattern everyday bcoz on my way to work it will drop connection all together. It happens near Putney national rail station, after Barnes NR towards Twickenham and over Richmond Rail bridge after Richmond NR station.

t-mob HSDPA coverage is poor, all I can figure from all this switching and drops.

sometime it will also drop whole signal indoors near my home inside Saintsbury's, where my friends HTC diamond on Vodafone acts up as well and loose network connection. funny enough is that there is a t-mob shop right next door.

but we see other people talking on their iPhone or Nokia merely. so I used to think it was bcoz HTC radio quality was poor than Nokia or SE and my Touch HD win mob a poor man's iPhone.. damn

but now I think it's a combination of both htc and t-mob network. as my friends diamond would get network back quicker then my HD once we are near the opening.

for your note I live in SW12 and work in TW1. cheers
[Desire General] brummiesteven:
That is a problem I've had for 2 years on T-Mobile, I never really have a problem with coverage but if the connection changes ie switches between G/3G/H when you're loading/downloading something you can forget about loading that webpage until you get a stable connection and refresh.
[Desire General] scotch whisky:
Mine does switch from 3G to H when I download something from the market. It then immediately switches back to 3G.

Maybe I have been with T-mobile for too long. I thought this is what it is supposed to do. Isn't H 3.5G? I stand to be corrected.

It certainly doesn't drop the connection and I don't have any speed issues.
[Desire General] brummiesteven:
H is technically 3.5G in the sense that it's not quite 4G, 3G+ in a way. That said the device would differentiate between the two.
[Desire General] firedup:
Excellent speed and HSPA connectivity all over UK for me, and in Berlin at the weekend. It's actually probably the best I've had on any phone on any network!
[Desire General] ninjakettle:
It's good to hear both sides from people with Desires. It helps further clarify that the issue doesn't affect everyone and so may be the handsets or perhaps even the particular masts we connect to that are at fault.

It would actually be more helpful if folk could specify when they say they have no problems and get great data speeds, that this is under 3G and not HSDPA. HSDPA works a treat for all it seems and this is not the issue.

Just as an FYI, the Tmob post on this page is interesting. In that they can replicate the issue.
[Desire General] __WiZaRD__:
Where are you based, if you dont ming me asking?
[Desire General] Madgerr:
Can you post your ping times?

I'm no expert but the way I understand it is to think of ping times as the dialling tone & the download speed as the answered call. ie if your ping time is too long it goes to answerphone (or the web-page times out). If your ping time is short the call is answered (the web-page starts loading) and downloads at the speed you achieve with your speedtest app.

I hope my analogy works for you.

Anyway, like others my HSDPA connection is great with around 1.8Mbps download speed and a ping time of between 100-130ms. On 3G my download speed drops to 0.02Mbps with a ping time of between 500ms-"not achieving connection".

For comparison, my home broadband (ADSL not Cable) is normally around 40ms.

Based in and around Bristol.
[Desire General] HoneyBeFly:
Hmmm to be honest I never noticed about this issue because it seems that when I'm using data where I'm based it almost always uses HSPA but my worry is that when it is stuck in 3G (as in not going up to HSPA or down to 2G/GPRS) then I won't be able to go online or even use basic calling/texting. This happens several times when I'm travelling. To those of you who never experiences any problem with 3G, are you very sure that you can use data when it is STUCK on 3G (as in the logo shows 3G and doesn't switch to H) or can you only use data when it goes up to HSPA (the logo switches from 3G to H). I have NEVER been able to use data while stuck on 3G :( but as I said before, luckily most of the time I get HSPA :o
[Desire General] Madgerr:
You could try going into Settings>>Wireless & networks>>Mobile networks>>Network Mode & setting it to GSM Only?
[Desire General] HoneyBeFly:
But then there would be no point of having the Desire if I only wanna use 2G haha. Like I said, about 90% of the time I have no connectivity issue. Actually, it happens once last year when I was using my LG Viewty as well. I couldn't receive calls/texts when it was stuck on 3G (my friend kept trying to call but was sent straight to voicemails despite full bars 3G signal) so I'm pretty sure it's an issue with the T Mobile network (reading their forums, they have pretty much acknowledged it).
