Hello All,
I have a problem with my kaiser, it started i think 2 weeks ago. I have vodafone (netherlands) with a data connection account (hsdpa). Now is the problem that i can't use umts (3g) or hspda. The only thing i can use is gprs. It looks like the modem or something is broken. But that is a kind of weird because (if i understand correctly) its al the same chip (wifi and so on). When i open internet explorer it begins to connect a gprs, 3g data connection. But it can't connect, than you can see a X by the synchronisation arrows (on the top of the screen). And after a few secconds it comes with a message that with the current settings there can't be a data connection. But if seen other messages as well ( the modem on the other side disconnected the connection) The weird thing is that i tried my sim card in my friends kaiser there it works fine, so it have to be my kaiser.
Ok what i tried:
I have a dutch htc kaiser (not vodafone branded or anything)
I use the latest dutty rom, but i tried the orriginal rom and different roms to see if the problem was the rom or something.
When i let the 3g mode on i can see that the phone finds a 3g connection (to call over umts).
Is there any program or tool or something so i can test the modem?
Or does anyone know a sollution for me, i will be very greatfull!!
Ok i tried a other radio to, maybe this was the problem. But it didn't, at this moment i have the default htc dutch rom (who was on the phone when i got it). I searched the net for the same problems, what i found was that this error could be happening when you have your wifi connection open, but i have wifi disabled. The phone is still receiving a 3G connection, but after a few secconds the 3G icon is gone and the failed synchronisation icon (two arrows with an X) is visible. than you can see that the phone is reconnecting. and then if i want to connect to the internet the same story as above is happening.
When i search internet i couldn't find an tool to test the chip/modem.
Because i have it spl unlocked i can't return it for rma, is it posible to restore the default spl?
Hi,
unfortunately I have the same problem with my Kaiser. I have an unbranded German version and it worked fine with all bands (GPRS, EDGE, UMTS(3G) and HSDPA) but since two weeks ago its only working with GPRS and EDGE mode. I have to change band-selection from AUTO to GSM in order to make or receive any calls.
I didn't do any ROM flashing, everything remains the same as the device was shipped.
I assume, that something is damaged but I have no idea how it could happen or how I can find out exactly what is causing the problem.
Since there is still warranty I'll return my Kaiser soon.
seems to be a widening problem
hi,
it seems many have the same issue, see my other posts for linkage to some other threads on it...no solution yet as far as I can tell.
rich
p.s. moderators any chance to link these threads and make a sticky?
ok, thanks for your reply. I've allready found another thread for that issue. But im still uncertain if its a bug in my device or a combination of a bug with a provider specific (Tmob Germany) problem or if its only the provider to blame for??

I have a slightly different problem. I don't have 3G in my area but only EDGE. Now the problem is that I cannot get speeds higher than about 80 kbs with EDGE.
Now when I put the same SIM in my Touch I can get speeds upto 200 kbs. So obviously this is not a problem of my service provider but rather something wrong with the device.
I have repeated the trial by swapping SIMs a number of times but with similar results all the time. Really don't know of a solution. Will appreciate any help.
haven't seen the edge problem
hi,
my edge speeds seem to vary more by location...I measure up to 200+kbs but have seen it go much lower too. there is a location where I can still get 3G working and i measured up to 1.7mbs for downloading! At my home location it is sporadic edge only and I can't even always get to speakeasy.com to test it, sometimes the speedtest says its not licensed..switching to wifi and it works. My guess is some needed ports are getting blocked by at&t at times..because sometimes it works. I brought all this up with at&t..they are taking some charges off this month and switched me to a cheaper plan too...so they at least seem to care even if they can't quite fix things yet.

Firstly, let me thank everyone who does all the SUPERB work on this site, developing software, ROMs, and tools that us normal users would otherwise never see...
Here's my problem:
I got a Kaiser with the shipping AT&T ROM on it - I'm in the US.
I wanted to get rid of the bloatware and other crap that AT&T puts on the device, and take it back to an HTC ROM.
The problem is, I can only connect to the EDGE network, and I'm only getting 40-60k transfers - I know that with my Samsung Sync (my previous phone) I was getting 1.3-1.5Mbps using the same site to test (http://text.dslreports.com/mspeed)
Is this a limitation within the HTC ROM? If so, does anyone know if newer HTC ROM's (perhaps even with WM6.1) will fix this problem, or do I HAVE to use an AT&T ROM to access the 3G (HSPDA) network in the US?
Thanks in advance for your time!!!
Do you see the icon 3G and it changes to H once you're accessing the internet? If no, you might want to check if you correctly config the connection.
I myself don't trust http://text.dslreports.com/mspeed when it runs on PIE web browser. I did the benchmark on 2 different types of connection, at&t HSDPA and Verizon FiOS* Wifi, and it comes up nearly the same speed 1.3-1.5Mbps.
*I have 15 Mbps download package.
Yes, it DOES do that (Mr President...lol)
What site do you prefer to test the speed of your 3G connection? I was hoping to use Speedtest.net, but doubt that they support mobile.
So, I guess that you're saying my connection is probably just fine, but that the site is problematic?
Thanks for the quick reply, btw!!

I don't pay attention too much on speed. But, there are many ways to confirm that you're connected to 3G network.
If the answer is yes for any question below, then you're 3G.
a. Tethering internet via your PC on "internet sharing" mode and make a call at the same time.
b. Stream any audio broadcast with bitrate above 196Kbps.
Enjoy.
Um, where do you live? Pretty much only the major cities have 3G deployed, and even then, it's no guarantee. I live in Minneapolis where 3G was rolled out last November.

I'm in Pittsburgh - I know for certain that I'm in 3G territory, as I just got the Kaiser a few weeks ago, and before that, was using a Samsung Sync tethered to my laptop, and getting 1.3 - 1.5 MBps....
UPDATE
Must have had a lousy signal where I was trying it before - I tried it again, using the same site, and was getting 500-600k - so I guess it's hitting the 3G network, but for some reason, changing the 3G icon to an H, presumably indicating HSPDA.
All's well...can one of the mod's please lock this thread? Thanks!

I have this weird problem with data connections. I couldn't find anything simular to this on the forum.
My provider (vodafone NL) does supports umts & 3G, I got a full data subscription, and the area i'm in is fully covered.
Now if I go to Settings - Phone - Band there are 2 different settings you can tweak; 'Network Type' and 'GSM/UMTS Band'. Those are standard set to 'Auto'. With those settings my phone says it has 3G connection (above the indicator bars and an icon), but i can't make any calls or get any data from the network. sometimes it also says the server ended the connection, but it still remains connected.
If I set Network Type to GSM, I can make calls, but only connect trough gprs wich is waaaaay to slow for me.
Setting it to WCDMA won't give me a connection at all. Turning HSDPA on or of doesn't make any difference also.
I figured updating my ROM would fix this, but it didn't. I tried different roms.
Is this a known problem, and more important, is there a fix for this ? It is driving me crazy !!
little more info;
ROM version : dutty's WM6.1 WWE
Radio version : 1.64.08.21
Protocol version : 25.74.40.02H
HTC branded Tytn II
Any advice is very welcome !!
Thanks in advance
i keep mine on auto but use bandswitch to switch between edge and 3g or some people gprs to 3g,sounds like a proxy issue since u wouldnt make calls on the wrong band,gsm works for calls so that part must be right so it has to be your internet settings and/or proxy
I checked the (proxy) settings on the website of my provider, and it seems to be okay. Those are settings for gprs tough, but it seems to me it should work as well for umts. It are also the settings the device initialy chooses for my provider..
I was thinking, might a radio update do the trick...? I did read somewhere that has to do with connections..
not necessarily, radios are more so driver issues for hardware such as gps,bluetooth,wifi,keyboards and cameras. i highly doubt another radio could fix this one since i never came across this with any combo of rom and radio before
Well then I don't know anymore what to do. It is probably a hardware related problem so I'll have to make a phonecall to HTC.
Thanks for the advice dyetheskin !
If someone does have a solution... still happier to get it fixed myself !

I am having the same issue.
More wierd is that it used to work perfectly in the beginning and couple of days ago it started acting like this.
I called my mobile provider thinking it might be USIM problem, however it wasn't.
Now I also think it's a HW problem. Next week I'll take it to a lab and hopefully it will be an easy solution.
I called HTC Tech support 2 weeks ago, and they confirmed it was a hardware related problem. They had 2 simular cases before..
Well, at least they will repair it for free
Hi all,
I've got the following problem with my XDA Diamond (O2 Germany).
- To establish a connection, first the 3G connection is enabled. After the 3G connection is up, it switches to HSDPA ("H" icon).
- Now everything works fine, no latencies and fine transfer speed.
- After a certain idle time (surfing...), the H disappears again and is exchanged by the 3G.
- When I try to download data again, it switches back to "H".
=> Then, huge latencies occur (up to 1 min. before data are received), the connection speed slows down dramatically or no more data is received at all.
I first thought of issues with my ROM (Bepe 0.99) or my RadioROM (.05). But after flashing to Aztor V7 and RadioROM .08, I'm afraid I have hardware troubles as the problem persists.
Now my questions: Did anybody here have the same problem? If yes, could you fix it? If yes, how? ;-)
Would be nice if you could help me. It would be really annoying to RMA the device...
Thanks for your help in advance!
Regards,
eypostel
That could be because you device disconnected from the net (thus it switched from H to 3G), and it take time for it to reconnect to the net.
Thanks for your hint, but I think this behaviour is not normal...
Even the connection cold start (establishing 3G connection, then switch to HSDPA) is faster and before, the connection was working fine:
When in 3G mode the connection was required, the icon changed to "H" within one second, and the data transfer started immediately.
Now, it takes about ~30 s before the first life sign, and then data reception is not even guaranteed.

eypostel

Thx prodigy7, this topic exactly describes my problem...
I have a question regarding this HSDPA idle bug. Turning off HSDPA should bring relief, but my MDA Compact IV does not have the HSDPA-switch. Can anybody have a look in their registry which values are changed when HSDPA is switched off on an XDA or HTC device?
It is easy, simply save a copy of the registry with PHM RegEditor before and after the change. Then compare both files with a file comparison editor (PSPad or TotalCommander for desktop PCs does the job).
This is so ridiculous... I have bought a HSDPA-device (Touch Pro) because I wanted to use HSDPA a lot... and it doesn't work at all... this was my first and last HTC device... I have invested 600€ for a piece of crap.
The Diamond does HSDPA just great, however your service provider must support it. In the UK T-Mobile supports it on their Web 'n' walk Plus and Max services. If you have normal web 'n' walk you can see the H and connect using HSDPA but its throttled.
Nothing to do with the device, just the service provider. It also depends on coverage. For example, when at home I get a H with 2 bars. When driving to work I loose that and get 3G and then eventually just G. Because my provider doesnt have HSDPA coverage where I work.
To turn HSDPA on and off easily use a cooked rom, i use Duttys. Very close to the original and tweaked just a little.
Did you read the german thread linked above? I guess not because what you wrote is wrong.
It is correct that the problem only exists if you use htc devices in the O2-HSDPA-Network. But: the problem only exists with HTC-devices in the O2-network. I am able to use any other (non-HTC) phone that supports HSDPA with the same sim-card successfully in the O2-network. And I am also able to surf using HSDPA with my HSPDA-Surfstick in the O2-HSDPA-Network. This means: the problem is not the network, it is the device (=HTC).

If it was that simple then none of us would be able to use HSDPA on our TD, but most of us can. I can use it on my TD on Orange in the UK and other networks including O2 when I am roaming in Europe and, for that matter South Africa (not sure about Germany). So the problems probably lies with the interaction between them, rather than solely the "fault" of one or other.
Seriously, sometimes people can be a bit absurd. 3G & HSDPA are standardized communication protocols. This means that there can be little (no?) device-to-device OR network-to-network variation with regards to the integral working of 3G. The context and application might vary and impact performance, though. For instance if a device is not supplying enough power to its 3G chip, signal acquisition might be slow and strength weak.

I highly doubt the existence of a bug limited to a single network and device brand. By the way the Qualcom chipsets (which incl. the 'radio chip') are not specific to HTC and many companies (incl. Kyocera, Motorola, Sharp, Sanyo, LG and Samsung) feature them. The specific Diamond Qualcomm chipset (MSM720xA) also features in the G1, Xperia, Motorola Atilla & Alexander, LG Incite and MANY others.

I seriously doubt that. To prove this, you would need to test EVERY single 3G phone that has ever existed with the network. Which is, quite frankly, impossible.
Like I mentioned earlier (ct. 1st paragraph) context and application might influence performance. Maybe you're just not in an area with sufficient coverage, maybe your specific device has a design flaw or malfunction. Whatever the problem is, I'm pretty damn sure that it's not "HTC-devices don't work on O2".
I use the german o2 internet pack L and I have the same problem. Seems to be an o2 issue.

That is a much more feasible scenario. Any other O2 users have this problem?
I totally agree with H3x. You say the problem is only HTC devices on O2 so therefore its a device problem. but surely as the problem only exists on O2 its an O2 problem? Every other network in the world seems to be fine. Did you test any other devices with your SIM and network or are you just reading whats on the internet and taking it as true. As we all know, the interwebs is never wrong.
But, your obviously not happy with your diamond so throw it away, go and buy a nokia.

Seems like the HTC-homies in this forum are not willing to read what I wrote before and keep asking the same stuff again and again. I mean, I wrote in the previous linked post all details that you are asking again here...
I'm outta here and will keep at the german forums where people are not constantly trying to convince me that I am stupid...

You're right of course. The bug mentioned here is not limited to a single brand nor a single network. But it seems to be limited to specific Qualcomm chipsets. According to numerous reports in German user boards all (?) devices using MSM7501A (HTC Touch Diamond, Touch Pro), MSM7200A (SE Xperia X1) and MSM7201A (HTC Touch HD) have trouble reconnecting from HSDPA-idle in German O2 network. Doing some research on the web I found similar reports from Swiss Orange users.
From my experience as a German O2 user: An idle HSDPA connection switches back from "H" to "3G" after 25 seconds. If you then send a new request, e.g. tapping a link in your browser, the connection indicator of your device changes to "H" again, but most of the time the connection hang up. You have to manually disconnect and reconnect... Switching off HSDPA/HSUPA gives you a stable 3G connect, however limited to basic 3G speed. Another workaround is to frequently ping around, a 10 to 15 second intervall does the job. With pushmail or some IM messenger active it may work, too.
That's my experience with the SE Xperia. And it's definitely not a local network issue nor temporary - I'm using a Palm Treo pro, too, without any problems at all. AFAIK the Palm also is a HTC device running on a Qualcomm chipset, the MSM7201 without an "A".

Hi all,
I'm new to MDAs and to these forums so bear with me. I looked around quite a bit and have been unable to resolve my issue. I obtained an HTC Touch Diamond (a T-mobile Compact IV) in the UK and am trying to get it working in the US. While in the UK there were no connection issues but as soon as I got to the US the connection is unstable. I have managed to make about 10 calls in the US but they cut out after a short time and most of the time I cannot make a call or cannot connect to a network at all. It can always see Tmobile and AT&T but can rarely connect, and when connected can rarely call. I have flashed the TLR 3.08.07.16 WWE ROM and updated the radio ROM to 1.09.25.23
Any help would be greatly appreciated
from my basic knowledge of radio, uk networks use gsm while most us networks use cdma that mite be your problem!!
try going to start>settings>phone (in the personal tab)> scroll to the band tab and change ur network from auto to wcdma!! you may also have to change the band setting your using, but u may have to check with your network on what frequency they use
Thanks for the suggestion. Thus far I have only been able to connect on GSM, CDMA has never worked. I also have been using the 850 1900 band which I heard is the one used in the US. I have connected occasionally but am still having trouble.
