[Q] Radio

I'm on the 3 network in Australia and I find my reception is quite poor.
I understand 3's network coverage isn't as amazing as Telstra or Optus, but it is meant to be strong around the CBD, which mine isnt. Other friends on the network using non-htc handsets have perfect reception in places I don't. This leads me to believe it might be my radio. Even when roaming reception will drop out occasionally.
I have Radio-3.22.20.17. Are there any other Australian 3 users here? What radio are you using? How is your reception? Would a 6.35 radio be better? I've searched XDA, Google, etc and couldn't find decent radio information for the Magic, only found some for the Hero.
Thanks,

Anyone able to help?

i don't know much about the radio side of things, but is there anything else that could be affecting your reception?
do you have a cover on your phone?
does reception improve if it's removed?
have you contacted 3 to see if there might be a fault with your phone?

I have a cover, but reception isn't affected with it on or off. I've also had the phone checked and its fine.
I want to test a new radio/rom to see if it improves but I don't want to go back to Android 1.5 and there are no 100% working 2.1 roms, so I'll have to wait.

Are there any threads similar to this one? http://forum.xda-developers.com/showthread.php?t=563757

Hi there,
I'm from Australia as well. I used to use the new radio to be able to flash the cursorsense rom and it works great. Inside my office, most of the time I didnt get any reception at all but with the new radio, it did.
i switched back to the old radio to use another rom though. (at that time, rom for the new radio is not that much). at the moment, my mobile phone is roaming
you might want to try the new radio (I believe this takes more space than the old radio as my internal space just disappeared). however be careful with that, i think it's the error in flashing of radio n spl that can cause you to brick your phone.

I ended up trying CursorSense. I hate Sense UI so I removed it, but I didn't notice any signal difference. I also ran Before and After speedtests numerous times and averaged them and the new radio was slower for me

so sorry to hear that...
well, at least i finally found someone from australia using magic and a member of xda as well..

I've not used my Magic on 3, but I can relate to your signal issues on their network. The only contract phone I ever had was with them and I regretted it, call drops and poor signal no matter where I was, I used to work in the stock exchange building, you'd think a phone would have awesome signal there but I'd be stuck on 1-2 bars Sorry to say it, but I think you can blame 3, not your phone.

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?

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.

[Q] Please Please Help me on the bad reception issues

sorry if I'm posting this again
but please I'm about to rip my precious hd2 to pieces because of the reception issues
see it happens like this
I'm standing INSIDE my home
watching the signal
as it goes from full to half to none to service un available
all of this happens while I'm standing watching my phones signal dangles
and I cant make calls longer than one minute and then the call is dropped
that is also while inside my home
when standing outside
the reception is most of the times fine
but the call quality is below average
there is drop outs and weird sounds
I tried different radios (2.10 and 2.12 and 2.15(stock))
I tried different ROMS (windows 6.5 and 7 and android)
I never dropped the phone
maybe the only thing I did was removing the battery from the phone alot because I was trying to flash android when I first got my phone
please Admins and Experts in this great forum
help me cuz I'm about to go crazy
my phone is a T-Mobile HD2 with a yellow reset button
current ROM : Rafdroid HD2
Current Radio : 2.15
Current state : Hunting for network and draining off the battery
thanks in advance

What was it like on original ROM !
you could try a T-Mobile Radio & matching rilphone.dll or flash newest t-mobile ROM complete with radio & test to see if firmware issue or hardware.
Is reception in/near your home known to be a bit weak ?

Aint the rilphone.dll a windows based file? If so how would that have an affect on android? Im also having a signal drop issue
Sent from my HTC HD2 using XDA App

Well rilphone.dll is used in conjuction with the radio firmware, when in android it will not use the rilphone.dll so could cause issues for some users pending on network ect ect !
You are using droid ROM with Radio package designed for WM,just my thoughts.

thanks for replying
can you please post the links to a stock t-mobile rom and radio and a compatible rilphone.dll?
but I didn't have the chance to test it under the original win mo
but the reception was fine when I first bought it and I was using a non primary sim card in it
so I didn't really notice
but I travelled to another country
and started using it along with another sim from the same carrier in a nokia phone
the nokia gives full 3G coverage
while the HD2 is hunting for the signal
so any thoughts ??

I thought Android ROMs are known to have issues with 3G !? check thread of your ROM as may have info on this.
Have a look in HD2 wicki if you want stock ROM.
I use my HD2 worldwide, Thailand, Singapore, China, Japan, England, USA on Energy ROM (Dinik version) & radio 2.12.50 & reception works normally with 3G available when using SIM on 3G capable networks.
Android is still a bit buggy for some users & to be honest Android does not seem worth the hassle to me as a good WM6.5.x build set up well is far better.

thanks Mister B for the advice
I flashed the latest version of the stock WinMo on my device and it seems like nothing happened
still the buggy reception issues
seems like the antenna inside the device is not sensitive enough to receive proper signal because when I go to the roof of my house the signal is fine
but when I stay inside signal drops and comes back almost regularly
I just cant belive that this is a hardware problem
because since I got my phone I never dropped it
maybe the only thing I did was removing the battery while the phone was on a lot of times....
??? im so confused ???

I would like to add another thing
when I put my fingers on the bottom right corner of the device ( right behind the on off key ) the reception works flawlessly
and as soon as I remove my fingers it goes back the way it was
so this is a hardware problem right?

What was the ROM number & what radio was included in ROM ?
If you have warranty or insurance you could try getting a replacement.
Looking like it could be antena related !

RUU_Leo_S_HTC_WWE_3.14.405.2_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship
that's the rom installed for now
and I don't have insurance or warranty
I double checked that with htc care
I'm really really sad about this
..........

when i first got it i think it was working fine and i was flashing a bunch of different roms. then like a switch when i installed one random rom "core cell android nand" it had really bad reception.
it doesn't matter what i cant fix it, install or flash, i have crappy reception. i have put different sim cards where the "original phone had good reception" and still no change. i put my sim card in another phone and it has a good signal. i also tested it in a another hd2 and it 1whorked fine.
cant send it in, i bought it off of somebody.

Logcat Analyze - Random Reboots of HD2

hello together,
my beloved HD2 (EU Model) is subject to random (daily) reboots, no matter what kind of ROM I've installed (2.3.3, 2.3.5, 2.3.7, 4.0.4, w/Sense, nonSense). This morning I catched it rebooting. When I tried to wake it up (PowerButton), the ScreenSaver appeared, I unlocked the device, then it freezed, and after a couple of seconds it rebooted.
No I have attached my actual CATLOG. Any idea on what the reason could be??
I'm currently on the latest Energy (2.3.5, Sense 3.5) Build, with 5/200/5 layout and a 16GB SD-Card with 1GB SD-EXT.
Any help is much appreciated! Thanks a lot!

Sorry couldn't stop myself.. Have a nice day
btw your logcat is clean, nothing wrong about hardware or anything about reboots..
could be bad blocks, boot your phone into the tri-color screen, attach the usb cable and ensure you have the "old" usb driver installed, you will find it on the definitive mtty thread for HD2, launch mtty, select usb in connection and press ok, a prompt comes up, type "info 8" without quotes (press enter ofcourse) and post the output here.
Oh, this is wrong section btw, thread reported.

Hello Rick, since I'm working with the same SDHC for at least 2 years, without formatting at any point, but with a lot of changes from ROM to ROM, I decided to reformat de SC-Card completely (with SD Formatter), and then install the ROM up from the scratch. Good or bad idea?

Hi Rick,
what does "Failed to find cpu subsys" mean? Nothing serious?

SIM Card related problem
Hello everybody,
Well...I'm suffering from the same problem you all are talking about here, random reboots (even in stand by).
I was researching here in xda, about this problem, and there's a lot of possible causes of this issue:
Overheating
Bad NAND Blocks
Motherboard soldering problems
Related problems with service provider signal and SIM Card
I can tell you that I suffer from overheating (playing games, youtube, browser, the back case gets very hot), and Bad NAND blocks (2 on boot partition, 1 on system and 2 on userdata) but it seems that's not the problem (for me).
I live in Chile and I have a T-MOUS (1700/2100 for HSDPA), I used to use it with movistar (850/1900) SIM Card for the last 5 months, but with no data plan due to the fact I could not use 3G here for bands incompatibility. I recently switched from provider, to Nextel (1700/2100), and voala, 3G started to work, and in the same time, problems with freezing, random reboots, high battery drain, etc...
I've tried a lot of solutions, like turn off automatic time and zone, auto backlight, manual network selection, etc, but none of these worked out. I was about to resign when I switched sim cards with my girldfriend for an experiment of signal-loss during one night, and the HD2 (with movistar and NO 3G) started to work again with no reboots, normal battery drain, etc...
For me the problem is the 3G data connection (I use ICS ROM from tytung, with RMNET, i tried PPP but I lose connectivity, no 3G). I don't know if theres a problem with the 3G itself or if the signal carries something that causes all the problems (I reed somewhere that T-Mobile once changed something in their signal and problems started to appear). I wish I could try another 3G provider, but here Nextel is the only one for my T-MOUS that opperates in the bands I need, so there remains the question.
Now I'm registered in another network (Nextel R), that is their 2G network, and I've data connection via EDGE, and it's working flawless as expected. I don't know if there's a fix for this problem or if I've to resign.
tom2lee, can you post your actual network situation and datablan etc, so I can compare the case with mine, maybe we can help each other.
Thanks

Hi Zaidor,
thanks for your descriptions! I'm living in switzerland, which is a very small country in the midst of europe (north of italy and south of germany). We only have 3 network carriers, where two of them are sharing the same infrastructure. I'm personally registered at the "Sunrise" network (www.sunrise.ch). This carrier offers the same network options as "Swisscom Mobile", the #1 carrier here in Switzerland. Depending on pricing plan you can have anything up to UMTS performance. For me, with a quite cheap plan, there's only remaining GPRS/Edge, which is enough for my daily sync needs. For the rest I'm sporting a fast W-LAN at home and at business site.
I also tried nearly every type of ROM, and I'm sure the problems wheren't there with the old froyo roms, some years ago...
But anyway, I'm now living with that I think, due to the lack of alternatives.
Be blessed!
Tom

Have u tried with a different CPU governor and a higher minimum cpu freq?
I use tytung ICS v2.5 rom, with PERFORMANCE governor, minimum 576mhz and maximum 998mhz...works, no freezes.
Try and give me some feedback
thanks

Hi,
I have also some reboot with my HD2. What's the probleme?
I used the NexusHD2-JellyBean-4.1.2-CM10 V1.3a.
Thanks,
