All,
There seems to be an incompatability between the "current" G1 Radio ROM (62.50S.20.17H_2.22.19.26I) and T Mobile UK's network.
Even though this is the ROM they are rolling out to G1 users via OTA updates!
There are a number of issues including data connections that freeze and never re-connect without a phone reboot, incorrectly sticking to GSM in areas of good UMTS coverage, random disconnections from the data service, and a strange problem with the first SYN packet in most/all TCP sessions going "missing".
Combined with the ever-present problems with their packet shaping and web proxies and it's pretty grim.
TM UK are certainly aware of the problems unofficially - most of their (very good) UK-based support team tell people to lock their phones to GSM only, which does help a lot but is quite frustrating.
Anyone know whether there's a new radio coming that fixes this? Or a TM UK network fix? Or a better work-around?
Cheers
I am using an unlocked g1 on 3 in the UK and I am experiencing the same problems.
I was going to try downgrading the radio if possible but not tried it yet.....
I personally don't recomend a radio downgrade, especially if you have haykuro's spl. Instant brick
The previous radio doesn't work with cupcake.
I do have some speed issues in certain areas but I've not had any frozen connections that I couldn't fix by restarting the browser.. I actually assumed it was an issue with the hero browser, not the network.
I doubt there will be a radio update just for UK users. We are insignificant. As a Briton, you should know this by now.
I live in Carlisle, Cumbria and I have no problems with either 3G or GSM. Well, apart from the obvious lack of connectivity in Lake District
You can see my specs in the signature.
I am also a UK user, Im running a rooted phone with exactly the same setup as Karolis. Im not experiencing any issues either.
So if it's not the radio, it means that you either have hardware problems, or T-Mobile's coverage sucks in your area.
It is some sort of issue between the radio and TM UK- it was quite widely reported as being an issue when the Cupcake update was first rolled out, but things then went quiet. It could perhaps be regional, but it certainly isn't related to signal strength.
I'm aware of multiple people with the same issue .
Well, I guess some of us just got lucky while others not so much.
Did you try going to / calling T-Mobile?
Officially there is no problem - but they suggest you lock your G1 to GSM.
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.
Ok let me start this off by saying. I read through a lot of threads and none specifically address my current question.
Since switching from Windows Mobile 6.5 to Android. My unlocked HD2 doesn't hold a good signal. My network is AT&T. Before I could hold a signal on Edge without a problem. Now since my radio is 2.08.0000 SPL. I can't get anything better than GPRS with 2 bars or basically with no signal at all. Is there another radio I can use that supports Android and the WP7 roms without causing myself further issues?
Just as a FYI to those who alway believe no one is reading the zillions of threads or using google. I am and I haven't found an exact answer to my question that's why I'm posing it here with the hopes that someone had this issue and knows what the fix is. Thanks in advance to anyone who replies.

If anybody has a similar issue. I upgraded my radio to 2.15.50.14 and my carrier signal has improved. I've been running solid on Edge when I'm not connected to a router.
Hi,
Im having problems with my HD2 signal. The problem is that it searches for my provider on startup for about 2 minutes and gets max 1 to 2 bars only on the second floor of my house, although when it has a connection it has 3G. Its mostly at no connection.
I have a second HD2 aswell and that is running okey even in the basement.
No warranty, so no point of suggesting that.
Ive flashed many differents roms and radios, didnt help.
Any suggestions I should try?
Where is the internal antenna located of this phone?
Thanks in advance!
try swopping sims to see ifs its the sim, assuming they are both on the same network
If not swop out the sim with one thats compatable
Naah, its not the problem of the sim, because one of the hd2 works perfect with my sim and the other doesnt with the same sim. So if the second one doesnt have a grudge against my sim then it should not be a problem of the Sim. Thanks for the advice although!
The question im quite interested at is where is the internal antenna of the HD2, I would like to check the connections.
It's a know problem with many HD2's i think some sort of bug in android. Switch to 2G network only in the settings and ull have full reception all the time.
Try to remove the battery over night, and then reflash with Radio-ROM and OS-ROM of your choice.
worked for me, no signal issues since I did this.
Soz, wrong theard :/

You can flash a different radio version just like you flash other stuff. Be careful and read the directions though because you can brick the device doing a radio flash.
Go to your phone settings and "about phone" and you should find your radio version. Most of us use 2.15.50.14.
Click here for the HTC HD2 Master Radio Thread
Read and find out what might be best to use for your carrier and or location. I used 2.15.50.14 because it was recommended by TMOUS users which I am. Some people test different radios and see which seems to work best for them.
-Edit-
The radio controls stuff like your carrier signal, bluetooth, wifi, etc.
thanks i updated to 2.15.50.14 but im still having this problem . idk what else to try
Having some trouble with that also. So, the steps are:
Reflash Radio, than android and see if it works?
If it doesn't, anybody knows the best Radio for brazilian carriers? (Mine is Oi Santa Catarina)
Thanx.
Hello everyone!
I am having a very hard time diagnosing an issue with my Nexus 6P. Android 7.1.1 Angler-03.78 Build: N4F26T on AT&T unlocked. My network keeps dropping consistently. It works fine for about 5-7 minutes after a reboot or after toggling Airplane Mode. It goes on to attach itself to LTE and then subsequently drops to HSDPA/3G and then just outright loses network. It intermittently then comes back but usually hangs on to HSDPA/3G and the voice quality and data speed are just terrible.
I tried the SIM in my old Galaxy nexus (which doesn't support LTE unfortunately) and the network didn't drop. So I am convinced something is going on with the phone. This issue crept up this last Monday (03/26) and has been going on ever since. Has anyone had similar issues? If not, could anyone tell me how to diagnose this issue before I have to send it to Huawei? Because I am not very keen on sending away the only proper handset I have.
Thanks
I had a similar problem on Cricket, which uses AT&T's network. I never had good cell coverage in my apartment but it suddenly got so bad that I could only make and receive calls in certain rooms. Cricket wasn't able to diagnose the issue and I ended up switching my service to Project Fi. The problem completely went away. I now have a strong cell signal with full bars everywhere in my apartment. I'm not sure that sending your phone back to Huawei will actually solve anything but good luck.

This is a known issue just this month I experienced it myself, Try flashing different radios I was on 03.78 and had signal drop issues 03.72 and 03.75 have had the best results.
I flashed radio 3.7.5 and it did zip for me. I was on Sprint where I never had any problems and switched to AT&T when I got the 6P and never got more than half the bars strength when the service was actually working. After I switched to Project Fi I am usually on the T-Mobile network and get full bar strength 100% of the time at home. If I use Signal Spy to manually switch to Sprint I still get full bar strength in every room in my apartment. This is with the exact same radio that I had problems with on AT&T. I don't know if the 6P doesn't play nice with certain networks or if those networks provide inferior coverage but Verizon users have had notorious problems with this phone that caused Google to issue a separate radio just for them. Verizon customers are the ones who claimed to benefit from flashing radio 3.7.5. I have never heard of that actually helping anyone else and it definitely didn't help me. If the problem is partly with your network then sending the phone back to Huawei won't make any difference. You can try flashing a different radio but in the end you might have to switch carriers and if you can't do that you might need to switch to a phone that your carrier actually recommends.

It's strange because this happened just this week. It was fine before this week. Everything worked, I got proper signal strength and the connection never dropped. Now on my commutes I can see there is no network when I am driving, no maps, no spotify nothing.

Okay, I guess that's what I am doing today. I haven't modded my phone in any way, I am still on stock android. I am going to have to start by unlocking bootloader and flashing TWRP.
Good luck. I was in the same boat. It just stopped working but there was no Rom update that could have caused a problem.

Where do I find the old versions? This thread doesn't have the old versions anymore. 03.79 doesn't resolve the issue.
EDIT: I used 03.75 and that doesn't do it either. Time to try 03.72. I am so disheartened.

Why not go to AT&T first, let them know about your issue and have them provision a new SIM for your phone (free). I seriously doubt a different radio is going to solve your problem, but if you want to try there is a dedicated thread in General for flashable bootloader/radio zips, but you would be better served installing ADB/Fastboot on your PC and using fastboot to flash them yourself. The latest radio is 03.81 (from 7.1.2) The stock image files on Google contain the radio and bootloader img files. If the new SIM doesn't fix it, you may end up backing up your data and doing a factory reset.

Okay the latest factory ROM didn't work, I did a complete wipe and a factory reset. I will go to AT&T tomorrow and see if a new sim helps (I doubt it because this SIM works fine in my backup phone Galaxy Nexus but I can't verify LTE with that).
I don't know what my options will be after this. I feel like I am spending more time maintaining my phone instead of using it. Just disappointed, that's all.

Where do I find the old versions? This thread doesn't have the old versions anymore. 03.79 doesn't resolve the issue.
EDIT: I used 03.75 and that doesn't do it either. Time to try 03.72. I am so disheartened.

Yeah, I found it. Thank you. None of the versions helped though
I've been experiencing signal problems when downgrading which is not your case. But I got it solved by performing a factory reset. It's fairly straightforward once you have backed up your data. Worth a try?
Similar problem here I think I have found part of the problem
I have been having a similar problem ever since a recent update. I have tried everything found in this post. Recently I tried turning off my wifi and noticed the problem seems to go away. I have done a few searches to see if anyone has reported no phone with wifi on, none of the results so far have been very helpful.
Since I don't want to be without wifi, I have gone into the developer options and turned on cellular data always active, to see if this helps, so far this is working for me.

I did try that but it didn't work unfortunately. I called up Google and they sent me a refurb which was DOA but then later they sent me a new one which works just fine. So it was definitely a hardware issue on my old phone. I don't plan on updating my software because I just want this phone to work like a phone.

It happened either way. Wifi status didn't affect my issue. It used to die out completely. Google just sent me a new replacement (after a DOA refurb) and it seems to be holding. But I am not upgrading to 7.1.1 because I feel the issue might crop up again. So I am going to stick to 6.0 for now.
Update on my status
So far having wifi off has worked, until I ran Waze and then both GPS and Networking down till I quit and turned Airplane mode on and off. The previous change to Developer setting did not work.
I have been debating going back down to 6.*, has anyone had good results with this?
