So my HD2, currently on Typhoon's CM7 loses normal connection to the operator whenever I go to the country side or some thick-walled building. Earlier I had stock Windows Mobile, and CM7 on SD and problem persisted on both. Now I have CM7 NAND and it still loses connection.
My guess would be it is a problem with radio, but I have the mostly recommended one - 2.15. What should I do?
my guess would be you have it set to use 3g only, so when it gets to a 2g only area it drops signal? Its unlikely to be the radio version, although i do personally preffer 2.10.50 and 2.11.50 over the 2.15.50, getting a stronger signal with either of those over the 2.15
Sorry for digging it out again but I finally had a chance to go and test it.
I've tried all possible connection options in settings and no luck.

Hi, I have a problem that I suspect is an isolated situation, nevertheless, it has been bugging me for over a month now. Hopefully the community will have some insight.
I will try to report the problem in it's entirety:
I do have a shortcut on my desktop to Phone Info (*#*#4636#*#*). From here, the thing I note of interest is the CID, which I guess is the tower ID that my phone is currently connected to. Also of note here are the ASUs, which I'm not quite sure what they are, but they seem to correlate with the number of bars being reported (ie more asu = more bars).
I also use Hello IM (AIM app from the market) heavily, and I have "Show notification icon" enabled, so it works fairly well as a visual indicator of connectivity, or lack thereof.
Ever since I upgraded from Super D to an Eclair rom, I've had problems with 3G handoffs on Tmo. Basically, whenever my phone switches from Edge to 3G, or one 3G tower to another 3G tower (different CID in Phone Info), the connection times out. I see the infamous "up arrow but no down arrow" activity on the 3G icon in the notification bar. This happened just about everywhere I went.
About a month ago, I decided to upgrade the phone radio, from 2.22.19.26I to 2.22.23.02. For one reason or another, this completely solved my problem. I had no problems with handoffs, 3G just started working again.
A couple weeks ago, I downloaded CM6 and tried out Froyo. The first thing I notice is the weak signal on my radio. Before flashing the rom, I did a nandroid backup, and I know I had 3 bars of 3G signal where I set the phone down. After the flash, my phone had no 3G signal, and for some reason refuses to switch to edge; so my signal indicator is sitting there with an X over it. After some time, it finally does pick up a 3G signal--this is where it begins to get weird...
My 3G works right now, for the most part. There seems to be 2 very specific locations where it does not work. As mentioned earlier, I am able to check CID's through the Phone Info menu. I notice 2 CIDs where my 3G connection times out. By time out, I mean an apparent loss of data (ping doesn't work in Phone Info). This happens every time I am connected to these 2 towers. As soon as the phone switches off to another tower, data works fine again. The strange part is, even though I am not getting data, the asu and signal bars continue to move up and down as if I have a normal signal. The phone also makes no effort to switch back to Edge, even though 3G data is completely stalled (Hello IM shows as disconnected, ping fails).
This started happening since the CM6 update, and have persisted since then. Even after I did a nandroid restore back to my previous rom (Super E 1.02), the radio problem remains. Before CM6 and after I updated my radio, I had no problem connecting to these same towers.
In a nutshell:
3G does not work when I am connected to 2 specific towers since CM6 update
Phone makes no effort to switch to other 3G towers or Edge when connected to these 2 towers
When connected to these towers, signal strength continues to go up and down as normal; usually hovers at a consistent 2 to 3 bars with the stock signal indicator (4 bars max).
Currently I have tried flashing all the Eclair roms available, as well as my old Super D rom (still using 2.22.23.02 radio). Problem remains.
Does anyone have any idea what's going on?
I have my TyphooN CyanogenMod 7 v2.5.1 installed on my HD2 running tytung_r6 kernel and radio 2.14 (as 2.12 and 2.15 I would have the issue).
The phone randomly drops complete connection to the cellular network and WiFi connectivity all together.
I have to go in and search for a selected network operator and click T-Mobile and then it registered that network and everything comes back up.
I can't seem to figure out what is the problem I've tried various kernels as well GL_Core v7 and RAFPIGNA 1.8 OC but still have the same issue. I also switched to TyTung_R6 because on the other two I'd randomly get the SOD.
Thanks to all who answer
If you live in a poor coverage area, it could be down to that. As you have given insuffient info its hard to say. What coverage on:
2g?
3G?
Location?
Network?
wifi could be down to the settings, web down to APN's.
I would do a clean install (format the sd card) only back up date not settings (advanced tab) and try again
i do not have that problem and i use 2.15
If you live in a poor coverage area, it could be down to that. As you have given insuffient info its hard to say. What coverage on:
2g? Yes
3G? Yes
Location? Williamsburg, VA (near Hampton Roads VA (good coverage area)
Network? T-Mobile USA
Sorry about the lack of data before
I also just updated to Rom version 2.5.2
I have the following problem, when I power on my HTC HD2 sometimes does not detect a signal with two different SIM with two different providers. At other times it detect the signals with both SIM. If signal is detected after a time it loses signal (voice and data) and sometimes the signal return after a few minutes, in other cases it is necessary to reset the device. When I reset the device is no guarantee it will function, is a very random problem, both SIM work on another old device (no hd2) without problems. Normally, when it detect signal I can make calls, and after a few minutes the device can not make calls, falls silent and after a while you hear a busy tone, nor are incoming calls.
What could be damaged?
Hello,
Does this happen anywhere or always in teh same area?
From my side, I have a lot of problem to have some signal but I realized it was because my area was far from an antenna (even if being in a big town).
If you problem happens anywhere then, I would recommend to flash your radio: http://forum.xda-developers.com/showthread.php?t=611787
Hello.
I have a similar problem - sometimes i also lose my signal. At first i thought that it was random but then i discovered that i have good 3G signal but when i go somewhere where there is only 2G i have no service. this also happens every time it try to switch to "2G only".
I started noticing it after flashing Hyperdroid 3.0 NAND android on my phone in the place of Hyperdroid 1.04 (although i'm not sure it has anything to do with the NAND rom). I have tried flashing many different radios (2.08, 2.12, 2.15) and also different roms - both android and also the original WM6,5 rom.
If anybody could suggest something i would be very grateful.
task29, wipe all cashes & use more stable ROM
Dial *#*#4636#*#* phone information Set prefered network to GSM only, (or CDMA only)
Also press menu and select your band, rather than using automatic
UPDATE: I have noticed that I have only no 2G service. What am I doing wrong? From *#*#*4696#*#* under phone info I have enabled "WCDMA preferred". Can this be a hardware thing if I have 3G connectivity but cant connect to 2G network??
Hi everyone!
I've been having a strange problem lately - at random times and random places I suddenly have no service so i can make no calls. Then after about 10 minutes I have service again and everything seems to be just fine until the next time that happens.
This can happen at random places but also after I return from somewhere where there's not supposed to be any service (from the basement for example) it also takes very long (10-20 min) until I have service again. Also i have noticed that sometimes when I have no bars and can make no calls, I can still go online on mobile internet (not wifi).
It started after I updated Hyperdroid 2.01 to Hyperdroid 3.0. I have since then tried several times to completely wipe everything (have reinstalled WM6.5 (the problem persisted in WM6.5 also) and have wiped everything with task29.
After wiping I have reinstalled radio v 2.15.xx, MAGLDR 1.13, CWR 150MB partition and then reinstalled Hyperdroid 2.01 but i still keep getting the random service drops.
Can this be hardware-related? What else can I try?
"What else can I try?"
Your sim in another phone. Not just for 5 minutes, for a few hours.
Have you looked into your providers network status? Could be doing system upgrades.
Have you inadvertently set to use 3g only?
I didn't know that there was an option to only use 3G. But as soon as I switched to "only 2G" I lost the connection again so it might have something to do with that. How could I disable this "only 3G" (I can't find it near the "only 2G" option).
Also will try a different sim.
Thanks

sorry, not sure offhand, i used to know how to do it in winmo.
So now I have tried dialing *#*#*4696#*#* to enter "phone information" and there ir reads "WCDMA preferred" so that means 2G should be enabled as well. But when I select GSM only i dont have any service and under DATA it reads "fail because Radio Not Available". I have 2.15.xx radio rom installed, also tried 2.12.
Did your tryed to flash a other kernel?
I did. But the same kernel worked for me about a week before so this cant be it right?
Can this be a hardware thing if I have 3G connectivity but cant connect to 2G network??
thats not a hardware issue, sounds like a Rom problem. Test out the radios, and see which one gives you the best signal
I have tried different radios (2.08, 2.10, 2.15) different android roms (Hyperdroid 1.04, 2.01, 3.0, 5.30, MIUI gingerbread) and different WM6,5 roms. I have tried switching SIM cards. I have tried switching off ond on data connection. Have tried switching 2G/3G to 3G only and to 2G only. Nothing helps. I still get no service when I am in a 2G only service area.
Please help. Anybody?
finally, somebody with a same problem as me... i have tried to fix it for 6 month, and still can't get any 3g signal, i have tried task 29, wm 6.5, different android nand and sd rom.
but the 3g signal showed in wp7 rom, have you tried wp7?
I have not. Maybe I will. But my problem is that I don't have 2G signal - I do have good 3G signal though.
Tried to install Windows phone 7. No luck. Still no 2G signal. What does anybody think of this http://forum.xda-developers.com/showthread.php?t=1190180?

I'm the opposite, but did you able to browse mobile internet with the no signal?? If you can, and get 2g speed then it's not the hardware, as your phone still able to get 2g signal
Sometimes my phone can browse the net in 3g speed even with no signal, so i guess its a software problem??
Two or three times I have had G or E instead of H or 3G in the notification bar but although it shows me that it has service it wont connect to the internet neither can i take calls during that time. All the time that I have 3G or H connection i can take calls and I havent noticed that internet would be slow.
So I have almost given up hope. I have quite good 3G service where I live but still 3G is not that strong indoors and I have too much downtime so my next desperate step would be to open up my phone and see if I can find something wrong with the connectors.. I really dont want to do that..
Hi,
Was wondering if anyone got bad reception with their phone. I tried 3 different carriers since I had my ideos, in neither of them I ever had very reliable reception and lately the problem is getting worse. I'm running aurora 4.1a and I loose reception all the time, and the battery drains so quick because it's always looking and looking. My sister, my mum and my dad all have good reception (2 of them with my old carrier and 1 with my current carrier).. I can put my dad's phone (same carrier) next to mine.. he will have full bars with 3g and I'll have no reception at all!!!!!! Then it connects and disconnects again, and so it goes... Anyone having such issues?
Thanks.

I'm having the same problem, I'm running Aurora ICS. I use to always have good reception everywhere, Then suddenly I've just been unable to. Any help would be great! If I do find out any fixes to the issue myself I will sure let you know.
Good to know that I'm not the only one! Thanks. Hope we find a fix soon.
I've fixed mine now, What I've done is I've gone into Settings > Wireless & Network > Mobile Networks, and scrolled all the way to the bottom, and simply re-registered on the network and selected Use only 2G Data. Mines now working fine with full connection everywhere. However I don't know if our problems are exactly the same, however this is what fixed mine. Sorry if this doesn't help.
I have the same issue. Mine connects to 3G and has good connection, but then it simply disconnects and moves to 2G or reconnects to 3G some time later. That happens pretty frequently and I thought it was an issue with the carrier, but now I am not sure anymore.
Blefish, that is EXACTLY what happens to me, and I tried 3 major carriers in Australia (the only 3 that have their own actual towers). Just after I posted this thread, I happened to do the same thing as IwAsBlack recommended and... so far it seems to work. I have generally better connection and I haven't seen that ugly no reception icon since! Of course, internet browsing will be generally a bit slower but then again, it's better than staring at the phone for 3 minutes until it reconnects just to open Google.
You haven't stated which model you have. I got rid of a Motorola Bravo for at U8800-51 and I have excellent performance over AT&T (US). Crystal clear even with only one bar and I have never had a dropped call.
Have the same issue on any ROM with any mobile network in Belarus. Can't use 2G as recommended above 'cos of a huge use of mobile internet for some net-radio.
Sorry for bad Eng.
Its a U8800 Q&A forum, I didn't think that I had to state the version since I have a U8800.
Yesterday I tested and kept an eye on for the whole day! The reception since changing to 2G only has been AWESOME! Only had a drop out when I was in the subway (of course!) but aisde from that, I had amazing reception not to mention.. that my phone lasted the whole day with still 15% left!! (3G on, it would have to charge it twice while I'm at work) So, it fixed my reception AND my battery problems.

FYI, Ideos X5 U8800 describes four different models.
I know it does. What I meant is that I have the Normal U8800 model, so I didn't feel like it was necessary for me to point any variant model number like PRO or 51 or H, because it's STANDARD U8800
So we can make a conclusion that U8800 does not operate well on 3G. I can't switch it myself because I want to use internet too. And I am pretty sure we can't do anything about it, no matter if the problem is in hardware or software.

Mate, if you switch to 2G you will still be able to browse the internet! It will only be a LITTLE bit slower, better than having constant disconnection!!! I constantly use the internet to sync my gmail, send free texts, browse the net and a bunch of other stuff.. works even better on 2G with constant reception, not to mention the benefit of the phone battery lasting a whole day (AND still have internet).. so switch to 2G and you will like it... still good internet only with better reception
Same issue
Having same issue when using GSM/WCDMA auto or preferred modes. works normal on GSM network only.
Even when I have no signal of 3g, gsm is working in the background.
problem arises when I have a call, 3g signal drops to minmimun, after the call phone tries to reconnect with the 3g signal but drops the GSM signal in the process.
Try this , as soon as you disconnect the call, try to call yourself from other at that instant only. Your phone will be shown unreachable because phone drops the GSM signals.
