[Q] HD2 O2-UK only works in GSM - HD2 General

Hello, I am hoping someone can help me.
Recently i have noticed my phone keeps losing signal, often seeing no bars are even ! , i have not performed any recent hacks / mods it just started happening.
If i change the base band from AUTO to GSM i get signal , if i select WCDMA i get ! , i am assuming that since its default at AUTO that when its switching to WCDMA its messing up (altho i really would like advice if this is true?)
i have softreset and hardreset and currently have no 3rd party cabs etc installed on my o2 stock rom yet the problem still exists.
any help people ..

How old is your sim card? I had a similar problem a couple of years back, turns out the older type sim cards aren't capable of doing 3G, walked in the store told them the problem, promptly given a new sim card, 2 hours later all up and running again.
Never used the stock rom but may also be worth checking in comm manager, there may be a toggle switch for turning 3g on or off

originally last year when i got hd2 i had an old sim which was replaced, my stock rom doesnt have the toggle (im sure i can turn it on with a tweak) , however the problem isnt switching it on or off .. the problem is when its on my phone wont get a signal and it used to work

JasJar only works in WCDMA mode

I have my JJ since October 2005. It worked 100% on the original ROM. Early Dec. 2005 I upgraded to the then latest Radio and ROM's. No issues.
Then suddenly From January I cannot get the Phone to work or connect to a data connection. I was told to upgrade to a 64Bit SIM which I did but still no result. I have installed every release of the Radio ROM and every ROM version compatible on the Uni up to date.
When the BAND is set to Auto it will not give me a data connection nor will the phone work. When in GSM same result. When I put the BAND in WCDMA it works 100%. Data connections work, Phone works, SMS etc. Problem is it only works in 3G areas now!
HELP, after 2 months I'm pulling out my hear and carrying my SP3i as backup.
Bump
@postman
what other applications are you using? Have you tried to start a fresh system with no third part apps (ie after a hard reset)? Have you tried to use the .cab files from i-mate for your network?
When I had a JJ I had frequent connections/disconnectiond between GPRS and UMTS. With the latest Radio on my XDA Exec I don't suffer from such frequent switching and it seems to have improved the batetry life as well. I used radio rom version 1.06.00.
J,
At the moment with the new ROM no apps installed appart from the ExtROM. Local network .cab also installed.
Problem is not as such that swtiching is taking place, problem is in BAND = Auto or GSM the Uni does not work for neither phone service nor data. When in WCDMA it works 100% without any issues. Like I said the prob. with this is that 3G is not covered like GSM, so if I leave work the phone feature is basically null and void as only GPRS/GSM/EDGE in area where I live.
Maybe the 3G and GSM/GPRS works off diff stacks / protocols or even hardware?
Yours desperate,
postmanpat
@postman, if you have tried to reflash your JJ and still the problem persists and the original problem did not occur because you added any third-party s/w then my conclusion is that you may have a hardware problem. Contact i-mate they usually reply within 2/3 days.
I would say you probably have a hardware problem !!, the GSM and UMTS aspects of the phone are very separate !!!

HD2 no signal, shows exclamation

Hi everyone, my HD2 just stopped working with no signal at all.and shows a exclamation all the time, sim cards are no problem. i've updated the phone with official sw, still have this problem at the beginning.
has the phone been blacklisted?
is the phone turned on in wireless mode in settings? ( ya never no)
is it still under warranty?
My HD2 has done the exact same thing, just shows an !
it doesnt even try to find a signal.
phone was a tmobile UK version, which was unlocked to use any network.
the problem has literly just happened today.
have tried different offical roms, and different sim cards.

Just phoned my provider in regards to my phone, quoted the emei and have been told the phone is blacklisted.
they are sending a request to have it unbarred. will post the outcome.
I have had this happen alot with Vodaphone UK. This is a brand new number so doubt it has been black listed.
I can get this working my turning the phone to airplane mode then back to phone mode, this most of the time makes the phone look for a signal.
Usually happens to me when there is no signal like in a tunnel, the phone does not seem to try looking for the network until you force it to.
This is possibly a fault with the timeout of the HTC HD2. Could be once it tries to connect when out of signal the device gives up after a number of attemtps.
Does anyone know?t

I was searching before posting for just this problem.
It is really irritating me. The phone can jump from deciding there is no signal to sometimes even going to full-bar "H"!
I hav currently resorted to turning off 3G as at least that way I am eliminating the idiocy of it prefering 0/1 bar of "H" vs near full non-3G reception for calls.
Even so at times it will just sit there for ages having dropped a signal with the exclamation showing and then jump back to life [in the same place] with good reception.
I am also on Voda UK
Mine has done that twice, in 4 months. 1 time phone was turned off inside connections, no idea how? 2nd time I just shut off, & back on, signal was back, hasn't happened in months now?
so does anyone have a solution to this problem?
I've checked with my service provider and my phone is not blacklisted...
My SIM card seems fine and everything else seems fine, except it keeps giving me the exclamation mark.. most of the time i notice it's when i get out of the lift (but that could be because that's when i usually check my phone before I put it on my desk).
There are many occasions (probably 5+ times/day) where I turn my phone on (ie, off standby) after it's been sitting on my desk for an hour or so to check calls, etc and there is that dreaded exclamation mark.
I know the area around my desk does have a signal because the guy next to me on the same network has a strong 3G and 2G signal.
Sometimes going to Comms to turn airplane mode on and off to force it to look for a signal works, but sometimes it doesnt.
I've tried soft-resetting, hard-resetting, using different radios, different ROMs, etc and still no good.
Funny thing is, it's only been happening over the past 2-3 weeks.. and I'm not sure what triggered it.
It's really starting to frustrate the crap outta me and friends have been asking why they can't get through...
Any help would be appreciated.. . I'm trying to avoid sending it to the HTC service centre if I can because they're slooooow and the stories I've read about my local centre are pretty bad (when I had my HTC diamond).
Solved:upgrade your rom everything gonna b in place
Upgrade to what?
I am having the same problem, for a hile now. Been fiddling with phone settings parameters, trying to see the effect. One particular combination so far seems to work. Try this: Comm manager --> Phone --> Tap Change Phone settings --> Menu --> Advanced network --> GPRS --> select CHAP authentication --> then CSD Line Type --> select Data rate 9600(v.110). Then OK, Back, and Done with the Comm manager. Observe if the network pickup performance (switching from non-existent H or 3G to E or G) works better for you after that. It does better for me, so far.
I'm having the same problem - NO SIGNAL
Any solution?
i recently discovered that for my problem, it was to do with the earphones. Not sure why, but it only seems to happen to me not long after i plug or unplug the earphones.
I usually have my HD2 on my desk with the music going while I work, but every hour or so, I unplug the earphones and take my phone by itself out with me for a cigarette.. then I come back and plug the earphones back in.
Often when I'm about to head downstairs, I turn on the screen while the music is still going and i see the "!"... as soon as I unplug the earphones, the bars indicating reception comes back straightaway!
Not sure if it's a coincidence or whether it really does have something to do with the earphone/earphone jack.

I have just bitten the bullet and accepted the phone is crap at swithing between 2G and 3G signal so turn off 3G in a couple of locations when I know I get this problem [home - I can use WIFI] and my office.
HTC would not be drawn at all on un updated Radio and this problem being "fixed" in USA ROMs
Fixed
the very easy fix is to do this :
settings _ personal _ phone _ network then make network selection to manual ,, then choose ur provider,,, then u will have signal,, after that u can turn it back to automatic
100% working
Thanks a "fix" not a solution.
Rather silly to have to jump through hoops to make a mobile phone recognise available reception
Have the same problem
I have the same problem now, any solution for that?

Very Unusual Problem 2G Networks Dead, 3G Fine

Well this is a new problem. My G1 seems to have decided it will not register on any 2G networks any more. Tried 3 SIM cards, all the same situation where 3G works fine then 2G fails completely.
I had been experiencing random cut outs on both the WiFi and mobile connections since upgrading to the latest Cyanogen firmware so upgraded to the latest radio. That worked fine for a couple of days but now no dice.
Also worth mentioning is that the device was crashing sometimes when the phone gets too much in the memory (for instance with a couple of widgets running it crashes when you start the camera).
Any advice would be great
Have gone all the way back to stock (and most things in between) in the hope than it was a bad flash but not looking that way
Also had the back off to see if there are any obvious problems (like a loose connection or obvious burnt board), but still no joy. Anyone know what sort of costs HTC would put in to get this sorted?

Gsm signal issue

I have my sgs for 2 weeks now. GSM disconnects around every 2 days.
At service mode (*#*#4636#*#* - Phone information) i can see this repport:
GSM disconnects:
====DATA=====
State: inactive
disconnected with last try
at 00:59
fail because No Error
The question is: why does this happen?
Is this an android issue or a hardware problem?
Any pointers?
Thanks in advance

That's not the problem.
Gsm disconnects just like that ,at home for instance. And when I notice that and try to reconnect (settings- wireless networks- mobile networks - networks operators) it doesnt find ANY of them.
Then I restart the phone and gsm network is back.
If I dont notice disconnection in time (so I can restart phone, people just cannot reach me....quite frustrating...
i see what you mean now.
yes, i've noticed that on mine too, but.... that's because i was fooling around with some new Apps Widgets settings i was testing to control the radio and data to save battery.
Did you install any new Apps recently that might cause that?

Well I installed all kind of apps. but i have the feeling this problem was happening even before that.
And I dont need widgets to control data ( I think) because I set the sgs to use 2g networks only and I dont have apn configured( section is empty. Internet connec. only via wifi.

Well, my sim card is VERY old (2002) and the carrier (Telfort) is roaming into another carrier's network (Kpn) with no extra costs of course like real roaming, but still roaming (I get the little "R" next to the signal strenght bars)
Anyway this never happened with the Nokia 5800xm running Symbian OS and using the same sim card...
Starting to get pissed of with Android...
With Symbian you hack or root or tweak because you want to, not because you NEED to like with Android....
And then you prob. get side effects...
Thank you guys for your time
I would get a new sim card if I were you. Every android phone that I have had seems to work better with a good 3g sim.
Get a new SIM card.
same problem, different phone
i have the same problem on kaiser with flashed android on it.
sim is 2 years old, and now suddenly this happened, tried differents sim cards, but the problem persists. My guess is, it is a software problem.
Maybe i will report when I flash original WM6.1 rom onto it, if you are interested in the result
btw, this happened about two days ago and because of this im buying galaxy s so i hope the problem will be gone with new phone

Why you think the problem will be gone if it's still android and I also got it with my sgs? Or are you counting on Froyo?
Yesterday I upgraded my sgs to froyo jpc with kies. I am new with Android but the post of Aery was so clear that i didnt resist: http://forum.xda-developers.com/showthread.php?t=769400&highlight=froyo+upgrade
I did get stuck on reboot but could get out of it after applying a cache/data/factory reset on recovery mode (3 buttons)
Now I am being carefull with the 3rd party apps., and so far so good, no gsm disconnections .
Froyo is of course better that eclair but Android is still disappointing to me.
You flashed Android onto a WM device (i'm impressed); could you not teach me how to flash Symbian onto my SGS?
Voice dialing (over bluetooth or not) and proper connectivity control (network, data, gps and bluetooth) of android is years behind Symbian; and such a well written, light OS, it will just fly on a high-end hardware like the sgs; but that is an issue for another thread.http://forum.xda-developers.com/showthread.php?p=7938430#post7938430

I think indeed that's not the same issue. My problem is that the radio signal get turned off during inactivity. That's why I got connection back after reboot: radio signal gets turned on again; later I learned how to turn radio signal back on without rebooting, but that is just a remedy , no real solution.
Try to upgrade to froyo, make a factory reset and be carefull with 3rd party apps. With froyo you will need less interfering tools anyway
I dont thing that my old sim card is the problem, but i'll try to replace it anyway...but first things first
Btw dou you have 3g turned on? Cause I never...
Another mistery: When I have 3G on I see those bars (signal strenght) dancing and that "death grip" thing happening:http://www.youtube.com/watch?v=LROTHrTR92k
But when I have it on 2G only the bars doesnt move even if I strangle it with both hands.....
Please repport later how it's going...
I had the same issue, i sent mine back and got my money back, i had also tried with different simcards and resets and nothing worked.. so hopefully my new galaxy wont have this problem. Its strange that these problems are so rare though.. But as long i get it going ill be a happy man.
fourth day with JPC ( and 4 days after a factory reset) so far so good no disconnections . I think problem is gone...
Today just to be safe, I got a new sim card....the other one was too old anyway(8 years)
i have the same issue, for a few days i can't get 3g. i'm seriously wondering about sending back my sgs. i've ttried all the settings, changed my sim..nothing...begin to think it was a fullish thing to change Desire to SGS..

Well... this is not the same issue.
I have 3G (WCDMA) disabled. I only use 2G (GSM) and WIFI for data/internet connection.
I Dont have a data account, I dont need it therefore I disabled 3G in order to save battery.
If you do want to use 3G, just go to settings - wireless and network - mobile network settings - network mode and set auto-mode (GSM/WCDMA or 3G/2G)
If it doesn't work, apply a data/factory reset and try again.
And if it doesnt work, it's probably hardware related and you should return it or send it for repair.
My issue is more complicated; next to the fact that I dont want to use 3g, my carrier is roaming to another network and probably Android OS or the firmware cannot handle it properly.
Android is still premature and the "Samsung - Android integration" seems to need a lot of development as well.
It is just a shame that basic functions like proper connectivity control just wont cut it. And Google is not doing any good either.
And dont let me get started on the voice recognition issue......
Hardwarewise, the SGS is superior that htc desire.....I wonder how it would perform if running Symbian^3 OS or Meego.....
I get a great sound quality from the stock music player just by mixing the equalizer and using the music clarity effect...just great...better than any other device I tried.
And the OFFLINE Gps experience is just great as well: the combination SGS - Motonav - External Bluetooth gps device is working like a charm.
I wouldn't change my sgs just yet......
yesterday i was swiching sims to determine if is a sim fault and suddenly i have my 3g/h back. happy owner again. i've tried all to do this, from firmware upgrade to servide mode settings..i don't know why but i'm ok again...

Hello,
I know its been a long time since you wrote this thread but I just came by it!
I have the exact same problem with you (I had it since August) even now with the official froyo. I tried factory reset and no new apps (that could cause the problem) but it still disconnects randomly in GSM mode. However, when I have it on auto (gsm and wcdma) I have no issues. I just disconnect data from the power button in froyo. I am wondering if you ever found a solution..
Chryssa
Well, I am subscribed to this topic so I saw your post.
Good and bad news:
First the bad one: No solution yet, it keeps disconnecting IF I stay on "gsm only".
And the good (or a little better) news:
I noticed that on sgs, using "gsm only" or "gsm/wcdma (auto mode) makes no difference on battery consumption....
By the way, this is a Samsung issue, not really an Android one.
On a HTC Desire HD, you can use "gsm only" mode with no problems...
Thank you for your answer!
I noticed that about the battery too. So not too bad, I just have to keep it on auto mode then..
Same issue
Im having the same issue but in a optimus t the worst part is that i cant get service at all.. when i press change network preferred it wont change and when i try to press on turn on radio it wont work either....

[Q] Help with data and GSM losses of connection

I own a Verizon Motorola Razr M, bought in ebay to an US seller. I am in Spain and I use Movistar SIM card
The phone came with stock JB 4.1.2, and therefore I could not unlock the bootloader.
I started using it, but it had a problem that I am not been able to solve so far: after some hours of use, with no problems with GSM and data connections, it suddenly looses both connections, although the signals on the status bar still appear. I take care that signals have gone when I take the phone to make a call or surf the web.
I have tried the following procedures:
Change the net settings to GSM/UMTS
I rooted the phone with motochopper 1.1.2 exploit
I installed Safestrap 3.12 in order to be able to install other available locked compatible roms.
I tried these roms, following this thread here in XDA: Clean ROM 1.0. Clean ROM 1.1, Barebone New Base, Stock Deodexed.SDswap-Locked & UnLocked BLs-xt907-9.8.1Q-94-1, but no luck. This last one uses the last radio, but no way.
I also installed the [PATCH][GUIDE] Patch to fully enable GSM on Verizon CDMA Android phones. I could only install it on Clean ROM 1.1 however. It has been impossible to install it on the other ROMS. In any case, no luck again with the patch installed. Here I had a big problem because as I still had these problems, I got into *#*#4636#*#* in the dialer, and touched the band selection option: suddenly, the net showed no signal more and I was unable to make it work again: I finally solved this by installing the stock firmware from here with RSD lite.
No way. I still have this problem and I can not use the phone. I have also tried with another SIM card, but the problem remains. It is a shame because when the connection works, the phone runs very well.
Any help would be very appreciated

The problem also seems to become worse with the use of the phone: at the beginning, coming from a factory reset, It can last some hours before the problem occurs. But since it happens from the first time, it happens more and more frequently and the phone can not be used any more. It seems that there could be a software issue.
Another try disabling fast dormancy
I´ve just disabled fast dormancy, because my operator Movistar apparently does not use this technology.
For this, I have modified 3 lines from build.prop system file, as indicated in another site.
The 3 lines are:
ro.mot.ds.fastdormancy.disable=true
telephony.lteOnCdmaDevice=0
ro.telephony.default_network=3
Having fast dormancy enabled when your operator does not support it, seems to drain battery, and could cause other problems. That´s why I´ve done this. I have used root explorer apk from Google store, it is free and it automatically creates a backup of build.prop file when you modify it.
I keep the fingers crossed, let´s see what happens.
Fast dormancy: yes but...
After some days using the phone with fast dormancy disabled (for this, I also added this line to build.prop: ro.ril.fast.dormancy.rule=0 ; I read this for ICS Roms, I do not know if this command is also valid for JB, any comment will be welcome), I still get some cuts (less I would say), but at least the phone tries to restart the connections. For this, I have also installed the apk from Google Play called 3g reconnect.
In any case, any comment would be appreciated.
Issue not solved
I still get data and voice disconnections when I use GSM/UMTS or only UMTS modes. They occur ransomly, and they also occur as soon as I use a WIFI connection. I can only use the phone on GSM only mode, which is frustrating.
Any advise?

Hello,
I have tried both: using *#*#4636#*#* or using the usual phone settings. Sometimes I have also checked that the changes made with the usual settings appeared also dialing *#*#4636#*#*.
Yesterday evening, I tried selecting global mode instead of GSM/UMTS and it seemed to work for some hours, but today morming, the problem occured again. So far, the unique way I have found to avoid connection cuts off is using GSM ONLY mode. I have to say that I have tried with 2 different SIM cards but the result is identical.

I saw that there was the possibility to choose theoritically between US bands and Cellular, and I entered in that menu. It is not so stupid to try that if you have already tried 100 other ways.
In any case, anybody has an idea about how to solve this problem? I´m sure I am not the unique person having this issue with this phone.

You are saying the problem is now still there. Yet the radio partition is fixed. Please restate what has been fixed with the rsd flash & what remains unfixed.
Well I think I have fixed and solved the problem: I initially copied the APN settings I had with my previous HTC Sensation, because the phone operator was the same (MOVISTAR), the SIM card too, and I have not moved. In these APN settings, the proxy was "undefined" as well as the proxy gate. I wonder if the radio stucks looking for a proxy each time or whatever. I tried yesterday with completely different APN settings, with a concrete Proxy and a gate... and now I have not had any issue in the past 24 hours. I will still wait a couple of days to see if that was finally the reason.
Which in any case would be silly, because I just applied what was working OK with my sensation, but...
New APN settings: let´s see

After several days, the problem is still there. After setting new values in APN, it happens less often, but it still happens. I have to switch to GSM only mode.
2 days ago, I was surfing the net at quite high speed with no interruptions, for half an hour. I then shutted off the screen, on again some seconds later, and the connection was blocked, I had to restart the phone. It has to be a software issue.
I finally sold the phone
After concluding that I could never get rid of this problem, I sold the phone, informing that he would have to use mainly GSM only connection. Great phone otherwise, but with this issue.
This sounds like a Baseband Issue.
Europe I have found baseband:
sm_bp_101031.027.32.81P to be the most stable so far, with no H+ support though.
But most Carriers in Europe don't have H+ or LTE.
That baseband is part of build 9.8.1Q-66
Which can be all downloaded here:

The baseband from 98.16.1 had H+ support in Europe but connections dropped like crazy.
Same with 98.12.4, we remedied that with Aussie Radio at the time.
Maybe this may help some International users with Data and GSM Loss

I'm on 9.8.1Q-94-1(98.30.1.XT907.Verizon.en.US) and wanna use it in Germany. any experiences with the radio compared to the suggested one. Or is there another way to boost the performance of the razr m? Compared to my razr I the signal and data quality is really poor...
edit: my baseband-version is: SM_BP_101032.021.32.80P
edit2: ok... now i've flashed several basebands... and the behaviour of the phone is always the same... with the australian baseband of xt905 it wasn't possible to get an hspa-connection. dunno if its enough just to flash the radio-fw?!?!?
so is there an other way to get more stability in my region? i tried to flash the radio from razr hd retail germany. but i think the razr m don't like it when I fool around. actually I love the mobile, so i don't want to make it angry... your suggestions are very much appreciated...
