Where would I go about diagnosing connection issues? MDA+TMO - 8125, K-JAM, P4300, MDA Vario General

Not to give away too much specific information, but I've got a new TMO MDA and the building I am in actually has TMO repeaters. Other TMO phones get perfect reception, and I can even put this new sim into my old unlocked HTC Typhoon and get perfect reception, yet my new TMO MDA won't get any signal.
I'm attempting to scour the registry to find some bit of info or a bit to flip or something of that sort to diagnose the issue. Our TMO rep apparently has RF engineers working on the issue, but if I can fix it sooner than they can I'd be happy.
So, basically, only these new MDAs (other new MDA owners are experiencing the same issue, as well as SDA owners) fail to authenticate to the repeaters in this building. I doubt the repeaters have a list of phones that allow authentication, since the Typhoon was never released by TMO and that can authenticate fine. So I'm thinking there is some bit on the MDAs that is sticking to one band frequency or another, or something to that effect.
Any idea where I could look for info, whether it be a web source or maybe a registry key I could tweak or something of the sort? I got the engineer mode to work (after another registry tweak to turn it on), and it isn't showing any information since the phone isn't connecting to any tower/repeater.

when you go to select networks to use, does the phone give you a list of possible cell networks?

Sorry if i sound obvious....but:
1. Have you compared the Roms on the phones? Maybe the new phone has a different rom which is causing the problem.
2. Have you tried the phone anywhere else outside your building...
3. The engineering mode will still work even without a SIM installed, so if your getting blank information then I think you have an old Rom
Hope this helps

Answers to questions in the thread:
1. If I go to select my networks manually, and it searches for networks, all it finds is the Cingular network, which I can not connect to. It won't find the TMO network at all. But I know it exists because other TMO phones work fine with full reception, and even my old Typhoon works with my new TMO sim in it.
2. The roms on all the MDAs shipped from TMO USA 1.8.10.2 and GSM rom 01.09.10.
3. Phone works entirely fine outside of the building. The building is shielded, but there are repeaters in the building for current TMO users. I know they work since other TMO phones other than the new MDA and SDAs work fine.
4. As for engineering mode... interestingly enough, now that I do have reception (I'm at home right now), I also get blanks. I thought that because I didn't get any reception, I wasn't getting anything from the engineering mode. But interestingly enough, I still don't even though I have reception.
Methinks I do need just the GSM rom. Someone mentioned it in another thread in the Wizard Upgrade forum. Where might I get just that ROM, maybe I'll give it a shot and see if it fixes before doing a full ROM upgrade (which I'd like to do for performance reasons, but I haven't gotten a definitive answer whether I can revert back to bone stone TMO roms with extended roms and everything yet).

I woould suggest getting hold of one of the phones that works, back up the registry, and restore it to the phone that doesn't work. That would tell you if its a registry setting, or a phone/rom problem

Well, there are no phones that work.
The phones that do work are your run of the mill non-smartphone phones, not a WM5 phone.
Actually, that's not true since my Typhoon is running Windows Mobile 5, but it is entirely different than the MDA.
Only all the stock MDAs shipped from TMO are failing to authenticate to these repeaters. Makes me think that updated the radio rom would help, or something on the repeaters is blocking just these two phones (the Wizard and the Tornado).

Try updating the wizard with one of these roms:
ftp://xda:[email protected]/Wizard/Roms/Tmobile/

Well, I updated the radio rom to 01.12.10...
And still wont connect to these repeaters. The phone seemed snappier to connect when I stepped outside of the building, though. So there is a plus. However, there has to be some reason the repeaters in this building are not allowing my phone to auth.

Which Radio ROM for UK T-Mobile MDA Vario II?

Hi all, apologies for posting this, as there I know there's tons of other threads relating to this matter - I've spent quite some time reading (and being confused!) by them, but I can't seem to find a thread which a) has someone describing the exact problem I have, or b) giving a definitive solution. So here it is:
I have a UK MDA Vario II. It's my second one (replaced under warranty), this, and my first one both had a problem where I would seemingly randomly not receive calls or texts. The phone shows it has a signal, and the green light would be flashing to indicate service. However, on occasions, if you try to ring the phone, it diverts straight to voicemail. Sometimes service resumes normally (about an hour later) and I get a message informing me of my missed calls, and sometimes I have to do a soft reset to get it working again.
What I have gathered from reading on these forums is that I may need to upgrade my radio - it had version 1.05.02.00 on it (which it must have been shipped with).
So - following instructions, I put HardSPL 2.10 on to the device, then flashed the Radio ROM to version 1.47.30.10, deciding that this looked the safest bet based on the feedback of other people on the Forum. Having done this (last night) I decided to test the phone once per hour today by just calling it, and I only got to the second test before it failed again - showing signal and green light flashing - but calls going straight to voicemail.
So - I don't want to do any damage to the phone - but I need to know that when someone's calling me, it's going to ring (we're moving house soon, so I'm relying on certain calls from solicitors, bank etc etc). Can anyone tell me of a reliable Radio ROM version for an MDA Vario II on T-Mobile UK? (which won't introduce further problems!)
THANKS!!

Ive never had any problems with calls not connecting, the only times it has failed is due to poor reception and ofcourse network busy errors.
I wouldnt worry about the radio version it sounds like a network issue. Have enabled 3G on it??

I have (and thanks btw - it was your guides that I followed attempting the flash last night). The thing is, a good friend of mine has the same phone, in the same area - and he doesn't get these issues. My other half is also on T-Mobile, but uses a Sony Ericsson and doesn't have any problems with coverage. I'm in a city centre right now, and my house isn't far out - we both have decent reception there.
In fact - an interesting thing just happened (literally..) - I have my phone on a charging cradle, and it had been dormant for a while, so the screen was off. It woke up, as if about to receive a call or text, but then nothing happened... so I called myself from my office phone - and it connected ok.
About 5 minutes later my girlfriend called me up on the mobile, and I mentioned the issue was still there - and she said 'yeah, i tried to call you about 5 minutes ago'.... so it's like the call was received (i.e. the phone new about it), but it didn't complete the process.
I had thought a new radio version might help (from my very limited understanding of such matters) - are you saying that's not the case?
Does 3G affect this too? What can I do - I use the internet more than anything else on my phone....
Thanks
does anyone have any further advice on this?
Mr Vanx? Anyone??
My phone is still randomly losing signal - generally not accepting incoming calls (though today it was not accepting calls, whilst I was still able to make them...). I think I may go and get it replaced by T-Mobile - but I have upgraded the radio to 1.47.30.10, and have put HardSPL 2.10 onto it.
I guess I need to downgrade to original versions, but I can't seem to find a guide which tells me if what I want to do is OK (and how...).
Please - can anyone assist - I believe my original radio rom was 1.05.05.00, and the SPL version was 1.01.
I'm using 1.54.30.10 and it's fine. I found 1.54.00.10 pretty good as well. Much fewer dropped calls comparing to any 1.4x RadioROMs. Signal strenght is also better. The only thing I cannot comment on is the battery life, as I charge the phone every night whether it's 90% or 10%.

did you have the same problems as me? - phone appearing to have a signal but calls being diverted to voicemail... seemingly randomly...
Use GSM mode as default
I have the exact same problem (I travel between Birmingham and London mainly) on my Vario II. It is really fustrating and my wife seems to think I dont answer her calls/txts on purpose(!)
On mine, the problem is due to the 3G mode - when I turn OFF 3G and use normal GSM the problem goes away. I get all calls/txt and internet connections sucessfully. When I turn on 3G the problem comes back - lost calls and unsucessfull internet connections. When in 3G mode sometimes it works somtimes it doesnt
Someone mentioned it could be that it is not switching between 3G and GSM automatically when no 3G is available. However, it happens even when in a good strong 3G area.
I swear this problem did not happen in the early part of my contract but only recently. One theory is that TMobile has sold so many 3G devices now both monthly and pay-as-you-go (esp 3G Data Modems with users using the network for their laptops) that the TMobile cells are just getting overloaded. Also, it could be that TMobile are also doing an upgrade of the 3G network and it is causing problems for users.
So what I do is run the phone in GSM mode as default (so no missed calls/txt and use Opera Mini for quick web surfing works well in GSM mode) Then switch on 3G mode if I am going to do any web surfing for more then 5 mins.
The added side benefit is also much much better battery life in GSM mode (3G soaks up the juice very quickly). I never use video calls ect so no loss there.
My Comm Manager has a toggle for 3G/GSM mode so I use that to quickly change between the 2 modes.
In Summary I would rather have a reliable phone for recieving/making calls then one which is hit and miss.
btw, Im now due an upgrade - wondering if I should stay with TMobile or not...
We appear to have the same phone 'lives'!

Ditto - im due for upgrade in March, and had been looking at the Vario iii - but am now wondering if I should be looking at another network? Is this a consistent problem with all 3G devices on T-Mobile - or does it just affect the Vario ii?

I signed up in Sep 06 and there was no problem with 3G mode then (problem free for the first 12 months at least).
From your phone internet rowser goto http://mini.opera.com/ and click on Download Opera Mini (this is latest version 4).
Before you do this make sure you have Esmertec Jbed midlet manager installed (Opera Mini is a Java App).
I use Opera Mini 90% of the time and its still renders fast on a GSM connection.
Ive uploaded the CABs for you for the Midlet Manager and Comm Manager.
I dont know if it only affects the VarioII maybe others can comment. If its a network issue then I would expect it affecting other devices also.
I want to go for the HTC Touch Dual (aka MDA Touch Plus on TMobile) as my next phone but may go with Orange if it is a network issue. Only reason I stay with TMobile is for the 'unlimited' web'n walk tarrif..but if I can't use 3G realiably then what is the point?

Thanks very much for loading this stuff...
my other half is after the touch plus too - but have advised her to do some research before committing to T-Mob again.... though if she gets it and it's ok, i'll post some feedback on here...
Cheers
The Touch Plus is a good phone if you can live without Wifi...Ive read somewhere that this problem is dependant on the area you are in ...in particular the TMobile cell tower servicing the area you are in and it is possible to phone TMobile tech support to get an engineer to investigate and correct the problem. In my case that would be my home address and my work address - maybe worth a try?
Just to add my 2p worth... my radio is 1.05.05.00 (came on the phone, which was a replacement for the first which had the screen drift)... I've had occasional times when the phone's lit up but nothing's happened, but I usually chalk that down to the phone doing an activesync check for push mail, and as there's nothing there, it goes back to sleep.
To my knowledge, I've not really missed any calls or anything like that since way back last year - when sometimes I'd be sitting in the same café as a mate also on T-Mobile, and we'd do the you-call-me-i-call-you thing to get each others' numbers - and it'd go straight to voicemail! That was quite amusing.
Nobody's told me that they've had problems trying to reach me on my mobile though for a fair while now, so I'd almost completely forgotten about this problem!
edit: yay, 500th post! Took a while but got there eventually... Anybody want to sponsor me with a free Kaiser?

Hi, I confess I haven't read the thread in great deal (am in a rush and am just passing through!) but you could try this official T-Mobile UK ROM. It's Windows Mobile6 and Radio 1.50.xxx (as far as I remember). The main thing is that it's official, and includes their latest sanctioned bootloaders etc. I flashed it to mine before taking back for warranty (as it's not possible to go back to the old 1.05 radio from recent unauthorised versions).
T-Mobile UK WM6 complete MDA Vario II ROM:
http://member.htc.com/ruudownload/t-mobile/TMobileWM6Step1-TMuk.aspx
sim
:O when did that become available? I swore to myself I'd keep an eye on the TM phone downloads site because I knew WM6 was available for some devices, but I completely forgot and since then they've rolled out WM6 for my phone... Which is a proper pain, but at the same time a really nice surprise.
Hard reset your device, install ALL applications on the phone (nothing on the micro SD - except outlook attachments). This should solve the problem.

Unlocking (X1A)

I realize that I'm likely to get instantly bashed for asking about this, but please let me preface my post with saying that I have done about 6 hours of research, here and elsewhere, but have not found a definitive answer to my question(s).
I recently purchased an xperia x1a. To my vast disappointment, the speeds i'm getting online are incredibly low (~200k). I know it has nothing to do with my service because if I pop my SIM into another phone, i get ~1000k generally.
My phone came "unlocked" and unbranded. I am in the US on ATT, and I can connect to HSPDA without a problem (isp.cingular as my AP).
I would like to try installing another radio on my phone to see if it might resolve my problems, but from all of my research, it sounds as though doing this requires security unlocking (CID) the phone.
First off, is there any chance my phone, brand new, came "security unlocked"? If so, is there any way to tell?
If I must security unlock my phone, it sounds like the code to do so is floating around, but since it's for sale places, no one is willing to give it away for free (or is it somehow linked to your IMEI?). I'm not altogether unwilling to pay to unlock my phone, although if there is any other route for upgrading to a better radio without having to pay, obviously that would be ideal.
I've got the radio I want, I've hex edited it so that it should work on my phone, but I'm very leery about bricking it by installing a radio that won't work. As I said, I have done a HUGE amount of research on this topic (flashing a new radio) and haven't found much that's definitive. On my last phone, a Diamond, I had no such issues (I purchased it retail, also unlocked and unbranded).
If anyone can shed some light on some of these questions, I would really appreciate it. I've been over to htccode and it sounds like they have a solution (at least for the X1, not sure about the X1A), but I would really like to understand this entire issue better.
Also, my current radio is 1.06.25.29. Can I simply cleanly upgrade to one of the newer radios found here: http://forum.xda-developers.com/showthread.php?t=477801 without having to worry about unlocking? are the radios for the X1 and X1A the same?
I promise, I've searched.
YUP 200 Kb only ???
My provider is TIGO and, same as you I assume, I use a "security locked" X1a under the HSDPA 850MHz band
If you are not getting better speeds with your current radio, I guess a Radio upgrade wouldn't help because I've been gettin' up to 3,500 Kbps downloads without any worries or special tweaks, and yes I started with Radio 1.06.xx.xx
Some possibilities:
1- Try checking your advanced network config (under start->settings->connections) to check if HSDPA is enabled
2- It could be an operator-config dependant issue; check your parameters in your otehr phone against the parameters auto-configured in the XPERIA
3- Check if your phone is REALLY X1a: remove the battery and the white label must say "X1a", not just "X1"
Finally, ALL RADIOS and EVERYTHING posted here @ xda-devs work for ALL X1, it doesn't matter if it is X1a or X1i
PS: The "security unlock" is ONLY required to flash Radios from OTHER HTC devices (but we have already managed to make them compatible by hex-editiing them )
hope this helps
I've tried everything i can think of and I'm banging my head against the wall. The phone's next. Actually, I think that I'm going to go ahead and get a new SIM from AT&T and see if that helps any, since I'm now having some issues with my blackjack all of a sudden....

HSDPA, will donate for help!!

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?

The post by pa49 was to DORMIU.
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 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.

HD2 Web Connectivity Issues and Analysis

Seriously people....
I've seen lots of threads recently. People are complaining that the HD2's data connection cuts out, leaving them unable to access the Internet from their phones for who knows how long. I know, it IS kinda annoying...But the thing is..
I can tell you this IS NOT a hardware problem. It's something to do with either the OS....or something in the phone's registry settings which no one has picked up yet...I hear that phones like the TP2 do not have this error, and I agree. My old unbranded Touch Pro 2 was brilliant, I could use it for IM and texts anywhere...LOL I used to sit on the Bus while people stared at my phone, while I was on Messenger talking to my phone. Anyways, here's what I wanna tell you guys. Hope I help out everyone in some way or another.
What I have:
HD2
3 Mobile Sim-So yeah, My Operator is 3 UK
Living in London, UK
Using ENERGY's 17th March Version ROM
HUSPA, HDSPA Enabled
What I've noticed:
The phone cuts out the signal when the transition between 3G and H occurs in the icons. As a result, the Internet cuts out temporarily, and programs such as Messenger lose connectivity for a while. For example, when the icon is on H, and no one's talking on Messenger, the Icon changes back to 3G....during this moment it cuts out sometimes..until it reverts back to the H icon (Got that? I know, it's a little long and complicated when I word it like that, but read it out and it'll make sense xD)
Now, whenever I have the phone connected to my PC/Laptop (Either as a Wi Fi Router or through the cable and then using Internet Sharing, either way, the phone does NOT change back to 3G, it stays constantly on H (Mind you, I usually download during this period). Anyways, the point being that the connection is VERY stable and constant, when in this state, connected to my PC/Laptop and the device is accessing the Internet through my phone's Data Connection. So what do you all think? And what have YOU found out? Leave your responses and ideas below
Some things I have found out are, if you Enable ONLY HUSPA in the Settings/Connectivity options, the connections seem to be more stable. Furthermore, if you really want to, Disable Advanced Connections, stay only on 3G, and enjoy a LOT of stability (At the cost of slower speed surfing and downloading )
My HD2 does not connect at all anymore. I called in to support because I completely lost data connectivity (web browser, email, slacker, whatever - no connection). They verified no troubles on their end. I moved the sim to my old touch pro (running Energy ROM w/ winmo 6.5 and Sense 2.1) and that phone connects fine. So it's not the SIM, and it's not the network.
I've also done a hard reset to get back to stock and still have the problem, which tells me that it's not a registry / software setting.
They only thing that leaves is faulty hardware - or firmware that a ROM hard reset wouldn't affect. Either way I need to replace the device altogether.
Unfortunately, tmo is out of stock and so I can only wait for a more to become available before it can be replaced.

Which phone company are you with? I experienced the same problem with 3UK in North London for a couple of months up until the beginning of last week but it was a problem at 3's end, not mine. Other people have been experiencing similar issues with non-3 phones in London (http://www.3g.co.uk/3GForum/showthread.php?t=102192).
yes, I had problems in London too before Good Friday. Especially on Tues+Wed.
Others around me inthe library also had similar issues with their iphones. I kept on switching the baseband and modes, and reapplying my 3G settings to keep it alive and solve the outages.
Most people with issues were on vodafone or O2 (like me).
It would work, then cut, then work.
I thought at first it was because I had a custom ROM, but iphone users had the same - and lots of timeouts on requests.
I DO believe however that running ROMS like energy's and Dutty's HG 1.7 with 2.10 (which I'm currently running) bases as 2_08 radios is not great for the uk and exacerbates the connection issue. 2_07 is better...and in any event we SHOULD be using 1.72 based roms with 2_09 radio.
I have also noticed that on COM5 23544 builds the opera mobile 9.7 and 10 google boxes do not work. They come up as failed connection, but then i click on teh link and it works...weird huh???
So I think last week was because of network faults in London. But in general, these 2.10 based ROMS and their radios are not ideal for stability.
I had perfect call and HSDPA stability with 1.48stock+2_09 radio.
Having turned to a 23544 rom (Dutty's HG) with 2_08 radio I've had much less call and internet stability (and quality) over the stock with 2_09.

No 3G

Hi i just brought and HD2 and can not get on 3G and I know I am in the 3G area. I thought by flashing to froyo's build it will work, but I am still having the same problem. I checked and made sure it is not in 2g mode either.
anybody have an ideal on whatis going on?
A OS ROM flash/Android build wouldn't really change your 2G/3G connectivity... unless it has a radio packaged with it. (HD2 compatible Android builds do not come with radios)
I would suggest going to the Radio thread and trying a different one, see if that works better for you.
just make sure it's a x.x.50.x radio!!!!!
(2.12.50.02_2 is the latest... been working really well for me here in the greater Seattle area)
yeah I updated to the latest radio also, same one as you and still nothing
I had similar after flashing to a new ROM, turns out it was defaulting my "Data Connections" to off, which killed out my 3G. soft resets, etc didnt help, took me 2 days to figure it out and finally the guy at the tmobile store who had the exact same problem prior helped me out. Worth checkin if you have something similar.
^^^how do I go about doing this? Where is it under?
