Hello,
i have a strange prob. on my o2 xda Diamond...(on o2-de)
When i start a Data 3G Data Session the Diamond will switch to HSDPA when Data is transfered..... works gerat.... but when the Data transfer is Idle the Diamond switches Back to 3G (this is how it should be....configured by the Network Operator) BUT then when Data is transferred again the Diamond switches to HSDPA for a short while and nothing happens.... the connection seems stuck.....
Somtimes the Data begins to flow after some Minutes, sometimes I have to dis/reconnect manually.
After a manual reconnect the Connection works immideately....but then.... the Problem appears again..
Is there anyone who encountered the same Prob?
P.S.: Yes, i did a HardReset and triple checked all Connection entries...
Same for me on the o2 branded original german rom. But now I'm flashing the DiamondProjectTeam-ROM.
Maybe the bug were fixed in the course of time.
Phew.... so I´m not alone with this Problem...
Im not quite shure if this problem was there a week ago.....
Even if i Update the Wheather Widget two times in a short interval (after fallback to 3G) the connection is stuck....
As far as I remeber this wasn´t the case a week ago after i got the Diamond.
Pleas Report if the cooked ROM behaves different...
Regards, Jan
Yes jkb770 ...
let me set up the settings on the new ROM. After that I will edit this post and report ...
.Edit.
Hey guys, sry for the delay ... But I was very busy.
After flashing to DiamProj V1 I determined no difference
But I was very surprised when I surf with PIE. There was no problem to be idle for a while. PIE connected immediately to the requested page; without reconnecting. Maybe is a opera problem? I tried it with the newest version of opera (9.5.1522), no success.
Great!
Thanks in advance...
...im just installing the unsingned HARDSPL......
German
Hmmmm it seems to be no WWE ROM
No German UI
And i still have the HSDPA Idle Prob...
..Nah.... worth a try
As far as I know this is normal behavior. If there is no data transfered the "3G" symbol is shown as indicator and as soon as there is data transfer the "H" symbol will be displayed in case HSDPA is available.
I can remember I also read this somewhere in the manual of my TyTN.
This is also no disadvantage because transferring no data with HSDPA or UMTS will take exactly the same time.
Read...
The Problem is that after the idle (fallback to 3G) the Connection freezes....
Means..... after every fallback from HS to 3G no Data will ever flow until disconnect...
Sorry, I missed that part somehow
My E90 use to do same thing aswell. Am on 3 network in UK.
I think its network deponded, not some think to do with handset.
Edit on post #4: http://forum.xda-developers.com/showpost.php?p=2398651&postcount=4
exactly same problem here, connection freezes after few minutes, works absolutely fine after reconnecting. Has anyone found a solution for this problem yet?
HTC Diamond with Duttys ROM v1.8, radio 1.00.25.07; and I am on O2 network in UK
Oh and one more thing. I don't encounter this on my Stellar (Kaiser) with exactly same network settings. I will try different SPL today. Will update after.
Regards,
did you guys try do install the new O² HTC Rom Update? 1.93 is the version, maybe it will fix that issue you guys have.
i barely use my diamond for surfing over hdspa - only wifi - so i can't tell about this problem.
btw hello, i'm the new guy
Hello to the new guy.
Now I have changed the Hard SPL 1.24, different radio as well and the problem still exists!
When disabled HSDPA and working only on 3G everything is perfect. Is it only problem with O2 network or has anyone experienced it with any other networks? (but then again, if it was a network problem Kaiser would have the same problem but it DOESN'T) I don't know what to do next...
At least it seems it's not just me experiencing this problem!
My connection also gets stuck when switching back to HSDPA (not always though) and this seems to be causing issues when I connect to my office VPN aswell (when i try to complete data intensive tasks).
I'm 99% sure it's caused by the phone and not the network operator since I've used an older model HTC with my current SIM (Vodacom) and I don't experience this at all then. But when I put a different operator SIM (MTN) in my Diamond I also get this problem.
Anyone figure out what it could be yet?
so looks like it's the phone's fault...
hehe... am not alone in this...i think its network dependent.. ve
tried several hsdpa device, usb modem.. same ...
There should be a kind of solution maybe a software that will keep injecting data requests at intervals to keep hsdpa from falling back to 3G..
bR
My problem is definatly not network related. I've tried with another HTC Touch Diamond (on another network) and I've got the same issues connecting the VPN.
It really seems as if the phone has a problem dealing with large chunks of data (or a certain type of data).
Don't know if this makes sense but that's just my experience with it sofar...
so is there any solution for our problem?
This is driving me crazy
I have the same problem as you guys on my X1. I've tried almost everything and nothing works. Has anyone found a solution to this?

Hi,
since 3 or 4 week i have the following problem. My Herald seems to have sometimes a problem to reconnect to it's phone network when it's loss connection.
The Herald seems to search for a new connection but without success. After a softreset the connection will be established without any problem.
What can do to fix this problem?
Interesting, i've never heard of such a problem. Are you in an area with low connectivity? Did you run the network wizard?
Maybe your phone just searches at its own pace.
Its.....ALIVE!!!!!
Hello,
i have a big problem with my varioIII. a 3g/hsdpa connection cannot be established. only GPRS is working properly. has anyone the same problem? maybe solved it?
i can`t switch to "auto" in the Preferences-tab for Network-Type. this won`t work. when i do so, then there is shown the "H" in the upper line. but not for a long time. after a few seconds the connection is totally lost. it is like there is no service. but it is. i can only switch to "GSM". the there comes the "G" and everything works fine. but i like to have a 3g oder Hsdpa connection. maybe a problem with the radiorom? i am using the last nothill firmware with wm6.1. but the problem came while i was using the original htc image. but i think it was not always like that. i can remember times when there was a 3g oder an H in the upper line.
thank you for help

Apparently the only solution to this problem is a return, because of defective hardware. I have the same problem and going to return mine soon.
So I connect to internet on PC via Kaisers USB which connects to HSDPa.
Problem is that HSDPa connection disconnects aprox. every 8-10mins.
I dont know why, on my Wizard everything works fine.
Where is the problem?
Thanks.
BUMP
So, im using kaisers internet connection on mine PC (internet sharing,usb) and every 10minutes connection drops.
Where is the problem?
Thanks.
Please provide some additional information. Such as: Carrier, ROM version, and Radio version.
I frequently tether for several hours at a time and do not have an issue with disconnects, so there is probably a settings issue that will not come to life until we know a little more about your situation.

Carrier name is "VIP" , location: Europe(Croatia)
ROM: WM 6.1(nothrills)
r 1.65.14.06
g 25.81.40.02H
d 3.14.00.00
I had the same network setup on HTC Wizard and everything worked just fine...
Have you tried any other ROMs or radios? I was able to tether using the NoThrills ROM back when I was running it.
You can also try reflashing the same ROM and radio again in order to eliminate any possible problems stemming from a "bad flash".
Do you have the kaiser tweak installed?
No i didnt try any other ROM or radio..
Everything works fine on that ROM and radio ,only internet sharing is a problem..
And yes i have installed KaiserTweak.
Do you have it set to disconnect your internet?
No i didnt set to automatic dissconnection...
Maybe try another tilt or reset the phone????
huh...i've finally setup everything on this ROM and everything works very nice...so i dont want to flash another ROM (of course if this is only solution, i will..)
strange how nobody had this problem..
NoThrills is a WM6.1 ROM, and your phone would have shipped with a 6.0 based ROM since 6.1 isn't out yet. Did you have this problem prior to flashing to NoThrills?
Well i didnt try on 6.0 original rom...
I've flashed it same day i've got it..
Think i will flash some other ROM..
Any suggestions?
Thanks.
When you say that HSDPA disconnects are you sure it's disconnecting or just downgrading to idle. On my Kaiser I see that when the connection needs to pull data from the net, the icon changes to H (HSDPA) and when idle it changes to just 3G but remains connected. I can see that it remains connected because the signal icon has the 3G logo on top of it.
Cheers!
Rayan
I noticed too that when connection is idle stands 3G icon and when downloading there is H.
But yes, it just disconnects..
When I'm using connection on Kaiser(not internet sharing), it doesn't disconnects..
Hi, the search button has failed me. (Two posts in 2 years isnt too bad is it?)
My issues is.... accessing the internet over 3g works fine (and HPSDA) Internet, push mail everything... however, If I drop out of coverage at any time my internet connection vanishes as to be expected. However once connection is re-established still the Internet fails to work. It shows connected to 3G or HPSDA but all websites time out and Activesync reports waiting for network.
The fix is to go Start>Settings>Connections>Connections>Manage my existing connections.
Then I simply "Next" thru all the settings until I get to the end. Press Finish. The data connection drops and the re-establishes and Im working again!?!! Very Annoying!
Im running. Duttys 6.1 Rom (April) and a few bits a pieces (It happens with nothing installed also and with another ROM I tried in desperation!) T-Mobile UK
Does this sound like a Radio issue to you guys? Should I try another Radio or Ditch Dutys Rom? (Which I love)
Any help gratefully accepted.
If Downgraded to WM6 (T-Mobile stock ROM) and Im still having this issue. Very frustrated.
I've found a few posts from the US who seem to have the same sort of issue. 3g does not recover after dropping out of service.
http://forums.wireless.att.com/cng/...thread.id=88007&view=by_date_ascending&page=1
Not sure what to do now...
I've had the same sort of thing, I just disconnect (Long press on the red End call key or click on the 3G icon in the top bar and hit disconnect), and let it reconnect.
I have exactly the same issue with mine as well and its only started recently. I too have found the only way to fix it is to go through and 're setup' the connection. Disconnecting and reconnecting, rebooting all seem to do nothing...

Which symbol is most of the time in the top of your screen G/E/3G/H...?! Check this one out also --> my 3G issue
I usually have a H (1 or 2 bars), when walking around my office this can drop to a 3G connection at times.
If I head to the basement, I drop to the Areial symbol or completely disconnect.... When the H or 3G connection starts again my Data connection fails as described above.
(However, I am able to make normal outgoing voice calls, not tried incoming yet)
Ok, I think I have a work around that seems to be working for me.
I set my BAND to GSM only as a test.... and it worked for the whole day, when I dropped into a NO SERVICE area the data connection dropped. When it recovered my data connection was back and working.
Obviously GSM is too slow, so I've now set my BAND settings to;
Network Type - WCDMA
UMTS Band - UMTS(2100+800)
And also diasabled HSDPA.
Currently everything seems ok... Now my connection does not drop from HSDPA>3G>G and back up again it seems to work fine?? Seems the issue may be with switching between the GSM standards??
I realise I wont get coverage in GSM only area's, but consistant data (Push Email) is just as important to me.
I've the same problem, but changing settings to gsm only is no solution. In this case I have to restart my Kaiser to get a new working connection.
I also have many Problems since updating to wm 6.1. Can I downgrade to the original german 6.0 or is there a really stable german 6.1 out there?
I've been getting the same problem as well for the past month or so.
Have been 'fixing' the problem by either putting the phone into airplane mode and back again, or rebooting the phone.
It's getting quite annoying though
Stopping the phone dropping to GSM seems to work for me. Leaving me with HDSPA and 3G.
I'm lucky to be in a good 3G coverage area I guess.
Im not sure who we should log this issue with? Carrier or HTC?
Are we all on T-Mobile having this issue?
i'm on o2 germany and a one day test with t-mobile didn#t show this error
with o2 i have this problem about three times a day
any new ideas since july ?
Sometimes i want to throw my phone away.
I'm still having the problem as well. Has anybody figured out a solution?
A strange problem..
I recently got GPRS activated on my sim..
When i try connecting on my Diamond, the E becomes active and it tries to connect.. But after abt 30 secs to a min, it says "Cannot connect for an unknown reason... etc etc.."
I initially thought it was a problem with the network..
But, when i put the same sim in my old Asus P525, set up the connection and tried to connect, the G became active and got connected within a few seconds!!!
From then i've been tryin to connect on my Diamond and have got connected about twice with E in the signal bar.. But that must've been some freak accident cos after a few hours i tried connecting w/o changing any of the settings and absolutely no luck!
I've tried almost all the cooked ROM's. And different radios.
Right now i'm on the Official WWE ROM 1.93.
Hard SPL 1.23 or 1.24.
And 1.00.25.03 Radio.
Any idea about what's wrong, guys?
Make sure you have the correct GPRS/WAP settings installed on your HTC Diamond.
There are different settings for Payandgo and Contract SIM cards.
You can try searching Google for them, or if you live in the UK try this website: http://www.filesaveas.com/gprs.html

prank1, the settings are right..
That's why it's working on my old phone..
I think it may have somethin to do with Edge and GPRS..
Maybe my service provider does not have Edge capabilities..
If i'm able to restrict my Diamond to try and connect to Edge and connect to GPRS instead, it may work..
Any way that could be done?

My bad - didnt see the 'set up connection' bit so I assumed you didnt have the correct settings.
I had this problem once but it went away with a ROM upgrade - that was when I had the XDA Orbit.
The problem may be that my phone does not try connecting to GPRS and directly tries to connect Edge..
Isn't the connection supposed to be G-E-3G, in that order?
Is there any way i can prevent my phone tryin to connect to Edge?
Can i make GPRS as first preference instead?
Anybody? Please?
From what i heard my diamond doesn't support US( or Canada which is where i live) 3g because of diamonds hardware so that's why it only connects to edge which is really slow... anyways to connect i had to phone rogers my wireless provider and they gave me my username and password which was needed to connect online. So i'm guessing it's the same for you if you go to
Settings > Connections > rogers internet( for mine) > Manage existing connection
from there you'll go to the next page where you can input your info.

Hey.. That doesn't seem to be the prob since i can get it to work on my old PDA with the same settings..
That phone gets connected and it shows 'G'.
What might help me is somethin to block my phone tryin to connect to Edge before it even tries to connect to GPRS..
I don't think that's practical, but wishful thinking..
I've had the same issue with my Diamond, I know for sure that the network settings are correct as it sometime connects fine and other times I keep getting the "Cannot connect for an unknown reason..." error- only a soft reset would resolve the issue. Seems a bit random but am trying to monitor what is causing it.
It always used to work fine on my Hermes. BTW I'm using Dutty's ROM on my Diamond.

Yeah.. Sounds almost like my prob..
Could it be a rare manufacturing defect sort of thing thats affecting our phones?
Cos nobody else seems to have such an issue..
And i keep changing between Dutty's and Panosha's ROM..
I don't know if it's same problem you have ,
but I had kinda same problem..
I found that the lame ActiveSync change the proxy of my internet connection and put in the internet connection proxy my local proxy at work, even I removed the proxy it didn't help (dunno why) , just by adding new connection from the advance and adding new name etc.. it solve the problem...

I've only had my Diamond (MDA Compact IV) for only about 3-4 weeks. I was so keen to flash to a different ROM that I did so within 10-15 hours of receiving the device; my point being that I didn't get to try out my data connection on the stock T-Mobile ROM.
The connection seems to be fine today...!

As I know something with Activesync **** the GPRS connection..

Ok.. Note the "E" in the first pic and in the second..
The first one is 'clear' and the second one is 'hazy'!
When the "E" is 'clear', my GPRS connects!!!
I found this out after putting a different sim card of a different network and connecting..
When i put the other sim card, i got 'clear' "E" and GPRS worked..
Then i put back my old sim card and on switching on the phone, the "E" was still 'clear'!!
On tryin to connect, it worked!!!! Even after several manual diconnections, it worked only cos the "E" was still 'clear'..
Then i reset my phone with my sim card and got the 'hazy' "E".. And back to square one.. Not connecting..
My question is, what does this 'hazy' "E" mean and how do i make it 'clear'???! Only then my GPRS seem to work!
Help!!!!!!
This is how it is when connected properly..
Cannot connect for an unknown reason
I also had this problem. To make my story short, I have a data plan with Claro Peru which I have been using with my Touch (not 3G phone) with no problems. 3 days ago I acquired my Diamond 3G US version. When attempted to connect to the HSDPA I got the error mentioned here (cannot connect for..., sometimes the "H" symbol was difusse [like in the picture in a previous post in this thread], etc). The root cause of this was that my data plan only have GPRS/EDGE activated, my network provider (Claro) differentiates 2G internet vs 3G (so no HSDPA/UMTS until subscribing to a new plan).
The **SOLUTION** for my case was to select under "Select your network type" the option GSM (Start, Settings, Phone, Band tap). The option Auto was the default. Thus restricting to EDGE my data connection (which is according to my plan). Also, on the same tap I selected UMTS(850+1900)+GSM(850+1900) under "Select you GSM/UMTS band". You have to select here the frequencies according to your country.
P.S. The problem was the same before and after I updagred my ROM to RUU_Diamond_HTC_WWE_2.03.405.3_Radio_Signed_Diamond_52.51.25.26_1.09.25.23_Ship. So, two things to mention here. 1, A ROM upgrade is not the solution for this problem (in my case). 2, you can upgrade the Diamond US version (my is DIAM110) with a WWE ROM upgrade.
Hope this help someone.

I have the Diamond on T-Mobile in the UK with the web'n'walk plan (HSDPA enabled - although not the higher-speed "plus" version). This happens to me every single time I'm in a GPRS-only area - when I have HSDPA coverage, it connects fine. In order to get it to connect, I have to open the Comm Manager, turn off the data connection and re-activate it.
Before anyone asks, my connection settings are all correct and I've tried numerous different main and radio ROMs - nothing makes a difference. I'll give this a shot, see if it makes a difference.

OK, I would try the option Auto for the "Select your network type" so the phone auto negotiates the technology in use (between GPRS or the much better HSDPA), but change the option for the bands according to your country.
Let us know the results!
