I have my JJ since October 2005. It worked 100% on the original ROM. Early Dec. 2005 I upgraded to the then latest Radio and ROM's. No issues.
Then suddenly From January I cannot get the Phone to work or connect to a data connection. I was told to upgrade to a 64Bit SIM which I did but still no result. I have installed every release of the Radio ROM and every ROM version compatible on the Uni up to date.
When the BAND is set to Auto it will not give me a data connection nor will the phone work. When in GSM same result. When I put the BAND in WCDMA it works 100%. Data connections work, Phone works, SMS etc. Problem is it only works in 3G areas now!
HELP, after 2 months I'm pulling out my hear and carrying my SP3i as backup.

@postman
what other applications are you using? Have you tried to start a fresh system with no third part apps (ie after a hard reset)? Have you tried to use the .cab files from i-mate for your network?
When I had a JJ I had frequent connections/disconnectiond between GPRS and UMTS. With the latest Radio on my XDA Exec I don't suffer from such frequent switching and it seems to have improved the batetry life as well. I used radio rom version 1.06.00.
J,
At the moment with the new ROM no apps installed appart from the ExtROM. Local network .cab also installed.
Problem is not as such that swtiching is taking place, problem is in BAND = Auto or GSM the Uni does not work for neither phone service nor data. When in WCDMA it works 100% without any issues. Like I said the prob. with this is that 3G is not covered like GSM, so if I leave work the phone feature is basically null and void as only GPRS/GSM/EDGE in area where I live.
Maybe the 3G and GSM/GPRS works off diff stacks / protocols or even hardware?
Yours desperate,
postmanpat
@postman, if you have tried to reflash your JJ and still the problem persists and the original problem did not occur because you added any third-party s/w then my conclusion is that you may have a hardware problem. Contact i-mate they usually reply within 2/3 days.
I would say you probably have a hardware problem !!, the GSM and UMTS aspects of the phone are very separate !!!
Can someone help me understand if this is a general JJ issue, or a function of the AKU 3.2 Rom Update 1.90.96 (Radio 1.13.00). It's not identified in that thread:
Many of my JJ issues have been solved by turning off UMTS until I need it. My battery improvement is negligible (when measuring mA consumption), but the following used to manifest due to the phone's inability to switch between GSM and UMTS elegantly:
Calls frequently go to v.mail
Dialing results in 'Dialing...' message with no connection - or even worse I connect and other party can hear me even tho I believe it's not connected
Dialing results in 'This operation not allowed' or something like that
Several other issues I forget
All this went away when I turned off UMTS. My understanding is that UMTS and GSM are completely different functions, and the phone sees a UMTS signal and tries to switch to that. Unfortunately it's too weak and the phone does not know to give up and go back to GSM/GPRS. After around 15mins of battling, everything goes tits-up until I reset.
Is this something that everyone with moderate 3G/UMTS coverage experiences? Or is this a ROM/Radio version issue?
I have a very poor UMTS reception in my house and have the same problems. I have tried different radio roms. My current solution is just using GSM at my home and only UMTS at my workplace..
my too...
my case is similar. I had with radio 1.09 and now with 1.13. looks is a problem when you move between zones with umts and other only gprs and the phone gets crazy. I think is related new speed available form umts (1,8 and now 3.2) that are producing special situation in the device.
Thaks guys - more helpful than you know: I was considering a re-flash, and my JJ is SOOO customised I would have written off a week getting it all back into shape. The HSDPA change may also explain why I didn't have this issue with the first JJ in country in January, but am definitely having issues now.

If you reflash only your radio, you wont loose your data..
hey,
i've changed my network provider a few days ago. before the change and also now i'm using the Duttys Topaz WM6.5 Leo R0 WWE rom.
since i've changed the provider, i have problems with my radio reception. when i'm inside a building i mostly do not have any radio reception at all.
i've also tried another radio version and at the moment i've installed the original htc rom. still the situation is unimproved.
do you know why?
thanks for ur answers!
If you have changed provider...and your phone is the same, suddenly your network reception falls down.... then it's obvious what is causing the problem I suppose. Your operator doesn't have a proper coverage.
Yup, It's almost certainly your network
You've done all that you can to diagnose the issue you have; Essentially, you've got poor coverage compared to your old provider.
I'd contact them soon (today, if possible) and make them aware of the situation. If you're not happy, you can either spend money on a range extender (you may not be able to install these in your workplace), or change provider back. Call them sooner rather than later, though. They may have a small time period (in the UK called a "Cooling Off" period) before contracts become binding, allowing you to test services and make up your mind before you're tied in to the contract.

Did you test in the same building with other phones? Unfortunately, it seems that the diamond 2 don't receive in areas with low signal ...

yes I did. my friends, who have the same provider, have a really high reception whereas I have none. so it can't be the coverage of the provider..
I don't know what to do :/
If it is not due to the hardware, HTC could solve the problem with a forthcoming version of radio or Rom.
I hope that this solution will be implemented with the next official ROM WM 6.5!
Hi
If others have good reception and yours is none with the same providers something is wrong somewhere,the HTC Touch Diamond 2 isn't that bad for reception, I've found quite good in very marginal areas.
You need to check your phone isn't set to just 3G, but Auto. It might be you have no 3G coverage but your phone is set not to switch to 2G which other phones you are comparing against are using.
To check this go to settings and click the Communications option, scroll down to Band and then make sure the settings are Auto and Auto. Has that helped.

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 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.
I have been reading mixed views about whether the the T9193 loses 850mhz compatibility once a cooked rom has been flashed to this model. Some say they lose the nextg connectivity and registry tweaks are required to fix this, whilst others say it is simply a hardware issue and that any rom can be flashed, keeping 850 connectivity. I bought this phone purely for its 850 mhz ability, but i hate the telstra bloatware. Can someone please confirm this for me.
Regards Romeash
I have a Telstra HD2 and use it in the US on AT&T 3G(850) with NRGZ28's rom without any problem. HSPL and ROM were the only changes I made.
Brad
where are you australia
my t9193,running v1.50 ozrom and 2.08 radio
there is a telstraband cab floating around that puts all the 850 setting back in the phone
works a treat in hobart
Yeah I've flashed several times and played with the band settings in registry. Changing the band frequencues in registry didn't make any difference so don't worry about it.
Radios did make a difference
I flashed to this ROM- RUU_Leo_HTC_WWE_1.66.405.2_Radio_CRC_Signed_15.32.50.07U_2.07.51.22_2_Ship
this got rid of the telstra stuff and seemed to give the best reception

Yep, I can confirm that too. I kept the Telstra ROM on my phone for almost an hour and a half before I got sick of it and flashed to something better. I have had no problems at all with connecting to HSDPA (and I've tried at least 5 flavours of cooked ROMS, and 6 or 7 different radios). Radio 2.08.50.08_2 works best for me, with full reception bars all the time.
The registry fix allows the 850 band to be displayed in the band options, but this is purely cosmetic and has no affect on the phone's ability to sync with the network. I haven't encountered a single problem despite numerous (and for a while daily) upgrades, so you shouldn't need to worry too much.
I would definitely recommend sticking to the HSPL and flash-overoUSB route though - much easier to recover if anything does go wrong during flashing.....
thanks alot guys, much appreciated. now i know i can go through with the flash. first i gotta get it repaired under warranty. the audio manager keeps crashing every time i try to play music through the music. ive used different micro sd's so i know its definitely not the cards. must be the phone.
