Opening my M3100

hi
i think that my m3100 is not working so well with the radio anymore due to a few connections needing to be resoldered, at least thats what i am hoping, does anyone know of a guide to help me through it or any clues?
thanks all

Is the unit insured? Would that be an easier route to go down?

yeah but before i spend the £50 excess i wanted to see if i could do this as i have all the tools at my disposal at work so can do it, i just don't know what i am looking for

You sure the radio is actually physically damaged?

Good question, it would be a pretty unusual fault and I might suspect software first unless it's had a good battering!!

well i have tried flashing many types of radios, it has the latest bootloader 2.10, IPL 1.04 and many many different rom's and each 1 exhibits the same probem, the radio will fail when i move to a stronger signal area, or to 3g from gsm, or when i try to make a call. i only think its phyiscal as a few other people have said they get the same problems as me and find after opening it and "fixing" it it works once again.

What did they fix?? and how?? There is a known issue that causes the phone to drop calls when moving in and out of 3G areas. The phone tries to swap to the "band" with the strongest signal 2 or 3G. Frequently folk report that when this happens they lose the call. The workaround here is to turn of 3g and only use GSM band. This can be done in settings or by using a "band switcher" perhaps danielherrero's one.

GSM problem Topaz

hello, I have a problem with my topaz GSM network, when I call or they call me the communication is choppy and eventually ends up cutting the call. Only happens with GSM, 3G operates luxury. I'm tired of changing radio and rom but no solution. Has anyone had this problem with the topaz? What should I do?
Thanks for answering.

Would have to be a radio issue.
Almost sounds like a mismatched RIL.dll for your radio....
Keep flashing radios until you find one that works.

thanks for answering so fast.
I am looking for information about RIL but not what you mean I could do from there, could you explain?

I haven't messed around with Topaz radios so I'm not sure how they are extracting them, but on the Raphael, they split the RIL.dll.
I believe the RIL.dll is only an issue if you have flashed a radio from a different device, being CID unlocked of course.
So, I'm not sure what all you've flashed to your phone.
Worse case scenario, flash back to stock ROM, see if you still have the same issue and take it from there. remember to hard reset after you flash a ROM as well.

I have no idea if this has to do with the CID, but the phone was Vodafone. The release by IMEI. Today I'm learning new names xD. Thanks

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.

Old Radio (3.22) vs New Radio (6.35)

Does anyone know what advantages (if any) the new radio has over the old radio? An official/leaked/speculative changelog from HTC or some other expert? Anything?
For example, are there some known issues with the old radio that the new radio fixes? What are they? Does the new radio improve the performance if the device in some way (battery usage, CPU/memory usage, etc)? Is it simply the end-of-life for the original Sapphire radio and they want us to be using the Hero one from a future support perspective?
The basic question I am asking is: why is there a new radio version and what makes it so special?
I've done some reading today and I realise that certain custom ROMs require the radio to either be old or new, so obviously you have to have a radio that matches what your ROM is expecting. I'm not asking about that.

I have the same question. Im not sure if downgrading my radio will cause me to lose some reception or anything.

The new radio/spl combo mostly change how the phone's internal storage is allocated to different partitions - system vs. userdata vs. cache. Without it it's hard to fit the system files of a sense rom on the system partition.
I do seem to get better gsm/3g reception on the new radio though, too - but YMMV.

Do you think it is worth it to downgrade? The only reason I am thinking to downgrade is because it looks like there are better roms for the old radio, specifically the CM5 ports, like the one by alan.
Any more input?

i downgraded to run cm5.07-stable (not alan's "version" though, i just installed cm+gapps+bcrook+o/c710). my gf's phone is still running new radio so i put the NR version of 5.07-stable on it and tbh i can't tell the difference without really poking around in there.
also, i notice that now i'm running old radio again i seem to have more issues with the phone not picking up 3g in areas i know there's 3g until i cycle aeroplane mode. i assume this is radio related and that it's a real phenomenon and that i'm not just imagining it...
but yeah, i think if you're already on NR and aren't sure, i'd try the NR CM5.07 version which i'm sure will soon be replaced by 5.08-t1 at some point. that said, using the radio changer tool is so freaking easy that it makes bricking virtually impossible so i guess you can't lose either way...

okay i have some issue here. after upgrade rom it seem i cant send mms.
is it because of the radio version?
As what i know radio can be specified whether to use GSM or CDMA reception.
not all country use GSM or CDMA as their default reception.
so is that because i use wrong radio version?
how can i know or found the right radio version, for example for GSM?
anyone here have clue...?

The radio version doesn't affect the phone's ability to send MMS. The Magic only works on GSM/UMTS - flashing a CDMA radio would probably brick your phone.
You probably messed up your settings. Call your provider.

i've been trying to find this answer - but does old radio with Froyo have a working camera? I know new radio doesn't. When I look at Froyo roms with 3.22 radio they don't mention if camera works or not.
Does anyone know? Thanks.

Yes they do, the froyo roms for the 3.22 radio do, but it's really not because of the radio, its the kernel that their using for that radio for froyo. The kernel has some good advantages if im correct but it also has its cons.. Correct me if im wrong.

thanks kein for your answer.
but then when i try dialing *#*#4636#*#* and find phone info, and go to the "set preffered network type" it is always pick "WCDMA preffered" as default. i know that magic only use GSM, then i choose GSM only, but when i try to set up 3G on my APN list, the phone goes back to WCDMA as default.
so my guess is if i want to use 2G network, then choose GSM.
otherwise, WCDMA as default for 3G.
but im not sure by sending/receiving MMS use which network (GSM/WCDMA).
any clue?

It should be WCDMA (same thing as 3G or UMTS) if you provider has 3G. It doesn't matter if you use GSM or 3G when you're sending an MMS, as long as you the right APN settings.

Signal issues on HD2

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.
