I got the Hermes (cingular 8515) a couple of days ago. And everything is just fine but the most important part. I keep having dropped calls in places where the Wizard didnt have any problem at all.
ROM: 2.06.502.3
RADIO: 1.34.00.10
PROTOCOL. 32.67.7020.10H
I had the shipped ROM but i had this signal problems so i upgraded to this one in the hope that the problems would be solved but same thing.
Cingular did change my SIM card to a 3G one. I was wondering if it is a different network inside cingular and that is why i have problems. I really dont care about 3G, don't use it. Would my problem solve if i ask for a new regular SIM?
Thanks guys. I looked a lot for the same problem already posted so i dont repeat but didnt find anything, wich worries me a little
Yes, it could be that, because if you're in a major metropolitan area it'll try to use UMTS instead of GSM.
In any case, there is a fix:
http://forum.xda-developers.com/showthread.php?t=286844
This is a small app that will allow you to quickly change back and forth between the two.
If you don't want that, there's a reghack to enable a Band page in phone settings where you could force it back to GSM. Check the wiki.
Wow! thanks! it looks like the problem was solved!
I won't know for sure until i really tested it. But this is what i wanted to try
Guys here is my situation. I have a Cingular 8525 for some time now I noticed that it was dropping signal and then recovering it I thought it was a radio problem but I changed numerous radios and it didn't fix the issue. Last night I noticed that it wasn't picking up any signal, on turning it on I noticed that I had No GSM I tried the way in the Wiki but I am unable to flash using the radio 1.16 to it I unchecked Allow USB connections but for some reason I cannot flash the radio. I started the phone attempted to flash the phone with several other radios and it just hangs. On rebooting I see NO GSM but when my phone starts up I see it reads the network but I cannot do anything else no calls nothing. Is there another way to flash the radio to my device or is the radio just dead? If so I have another 8525 thats not working can the radio part of it be changed?
Regards
It seems your phone is toggling between 3G and the older GPRS. By default, the 8525 automatically selects 3G if it is available. If you move out of 3G range (considering 3G support nationwide isn't great yet), which will happen often, you will lose signal temporarily and either switch to GPRS or regain a 3G signal. Currently I default my phone to use GPRS just because i can't be bothered with having to deal with dropping signal/calls as often as i used to with the automatic setting. There is a free tool called BandSwitch which can accomplish this for you. The newer version (2.1) is not free but if you can get your hand on the older version which is, it'll work satisfactorily well. I hope this solves your problem.
I had the same problem and nothing worked for me.
Try different solutions posted my various users and see if anytihng works for you.
I think it is a hardware radio problem and probably the only solution is to change the motherboard.
If it is still under warranty - get it done. If not, you are out of luck.
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 a problem. I must have tried 10 different ROM's in the last few days and I am getting extremely frustrated.
I have an HD2 (Telstra Version) that works on the 850MHz band for HSDPA.
Everytime I am on HSDPA, the location services stop working... Weather panel, Bing, Google Maps, nothing can find my location based on cell id... GPS works fine...
When i switch the 3G off... location services work perfectly fine.
I have tried different ROM, Radio combinations, but nothing seems to work...
I have tried NRG ROM, Dutty's HG (preferred) and ML series, but to no avail.
Can anyone help me troubleshoot this problem further, or has anyone else encountered this... I would really like some help on this.
Thanks a lot.. beers/coffee on me...
Taimoor
It works!!!
Bless this forum and bless the users on it!!!
Finally i think I have a fix...
Hi guys. This seems to be a nice friendly informative thread. I too WAS having the data disconnect on my phone.
I have the 1.66 sea wwe official rom. I tried every radio from the telstra radio to the new 2.08.50.08_2 radio. To tell you the truth I didnt notice anything different between any of the radios. So I really can't say if one is better than the other. But I started changing settings.
If you are in a 3G (H) 850 area I suggest this.
settings/Wireless controls/phone/band
for Network Type choose WCDMA
for Band Frequency choose the third setting. On Telstra rom it will be GSM(1900)+UMTS(850) and on any other rom it will be GSM(1900+850) and select done.
Now this should stop most of that switching you see in the taskbar of your phone. But this isnt actually what is causing the freezing. It has to do with your sms messaging I believe. I went 2 weeks resetting my phone twice a day. Then I went here.
settings/menu/all settings/connections/advanced network/sms service
Right now GSM is working for me. 4 days and no internet freezing. I believe your incoming email might be coming in by sms also. Notice you only get a few lines and have to download the rest using data to see the whole email.
Others on the forum have turned off email and their phones quit freezing. So if GSM doesnt work for you try GPRS and so on. This is only my opinion but I have been very happy for the last 4 days. Thanks for letting me share this info.
If anyone is interested I have made a cab file which is un-installable that will change the Band Frequency menu to the menu from the Telstra rom. It is mostly cosmetic but at least you will know what bands you are selecting. Use at your own risk of course. I have installed, tested, and uninstalled it myself. No issues.
For the last 4 days with these settings I only see 3G while phone is setting idle. As soon as I connect to the internet it switches to H. I am very happy with my phone now. Thanks matthewf01 for starting this thread. I should have came here sooner.

Hey guys,
i have constant battles with my HD2 running Android. The mobile reception and logically because of that APN is also not workin properly.
Example: I'm at home and have full mobile-reception and internet is working flawlessly. One second later nothings workin... The reception display shows 4/4 lines and one second later 0/4. But i didn't move.. Same with WLAN and APN..
I guess it's not a "build problem", cuz i had this with lots of builds. So it's maybe a windows mobile thing. I have flashed 2.12.50 radio and chucky droid rom.
I tried 2.14 but my conversational partners had very strong echos. (with MIUI-Build)
I searched the forum and googled but i didn't find any solution for this..
Really need this to be fixed.

I don't know a lot about android. But i had similar "echo" problems when i used a TMOUS based rom. I use miris 1.80 based rom with 2.14 radio in the uk on vodafone with no problems.
Miri Rom Here: http://htcpedia.com/forum/showthread.php?t=2520
Have you tried a RMNET based android build. The data connection with those is slower but generally more stable. I use ppp but do get the data drop off. but turning the mobile data off and turning back on again sorts the problem.
It would probably better to post such questions in the android general section.

Same problem here. Signal drops quite frequently and for now i like the sense builds which you cant switch to 2G (unless im missing something). With other builds if i switch to 2G its sort of fine but slow data connection.
Same here, I live in holland and use the 2.14 Radio. I don't have a data plan yet (the phone is brand new), so it doesn't really bother me.. yet
we really do need a fix for this
Is nobody havin an idea?
Me 2
I´m having the same problem...anybody know a cure for this?
no problems here ... 2.10.5 radio
Same problem here,tryed different combo's with wm and Android,radio's etc......signal drops now and then.
Sent from my Desire HD using XDA App
Always signal drops here.. 35% of the time. Mesured with battery indicator.. only in Android not in winmo and I didnt find the right radio and rom for less drops.
Thats so strange. About every 10mins i have a totally data loss. Tried different radios and roms. Nothing helped. As i tried 2.14 i had strong echo issues.
i uploaded some screenshots. They're all taken at the same place. So you can see how strange these reception changes are...

Boy I'm glad to see this thread, I thought it was just me!
I am having exactly the same issue, and have done since using android builds. The only workaround I have is to switch on plane mode, and then switch it off again which seems to work for an hour or two. But then the signal goes all wonky again.
I wonder if this is also affecting the battery life. I'm sure I read somewhere once that loss of signal results in more battery use as the phone is constantly trying to locate signal.
I have tried a number of radio/rom combinations with no real change. As mentioned above, if I switch to 2G the signal seems more stable, but the data is unbearably slow.
I'm in the UK by the way.

I have the same problem. I might try the 10.2.5 radio as above?
I had this issue with Android that signal drops for no reason. The trick to my problem? Disable in the Netwok Mode "GSM/WCDMA Auto" and choose "GSM Only". Now the signal should work flawlessly without drops. It worked for me
