[Q] htc desire won't connect to a network

Hi,
Two days back my htc desire suddenly lost connection to the mobile network. I now get a small cross on top of the signal bars and "no service" written on the notification bar. Sometimes this changes to "sos".
The wifi is working fine. t
The only problem is voice and data over the mobile network.
I tried a lot of things:
reboot
flashed a new radio
complete wipe/ factory reset
flashed a new rom
But to no avail.
A strange thing did occur though, at a mall, my phone suddenly started working for a few minutes and then went back to the same state as before. This same thing happened last night too.
I am unable to understand this and request all of you to help.
current status:
Phone: htc desire amoled
s-on
bb: 32.56.00.32U_5.17.05.23
miui 17.15

Ring your provider.

So I assume the problem would be the ROM
Any solution to this? Patches or something?
I would love to continue on using MIUI
Thanks all
Regarding the above problem.. had the same thing... what i did is this..
on dial pad use *#*#4636#*#*
then goto phone information (first one)
scroll down you'll see "set preferred network type"
mine was selected "WCDMA" I changed that to "GSM Only"
Since then no problem of S.O.S has come to me
I am sending it here because I am unable to post in the forum... something to do with minimum of 10 Post.. Hope this helps

Guys thanks for your replies.
I have already done the *#*#4636#*#* bit and it hasn't helped.
Regarding the rom, I was originally on cyanogenmod 7 when this problem started. I re-flashed CM7. Didn't help. Then i flashed miui. the problem remains.
Although I would like to add that over the past two days, at two different locations, I have been able to make one call and recieve one. How this happens, I don't know.
Still trying to figure it out but I just read elsewhere on this forum an exactly similar problem being faced by a few people during the last few days.... so keeping my fingers crossed.
Ah! and one more thing, I have tried sim cards of almost all operators and none work in this phone.

Same problem here aswell,
me too tried every thing,
but non of them helpfull..
Still searching for help

This may seem like a dumb question, but the people experiencing this problem, are you in the same country/region?

A little update in my situation:
I visited another city for an hour yesterday and the phone latched onto vodafone in seconds and worked like a charm but as soon as i got back to base, it was back to its dead state.
This is a really confusing situation because, one moment it seems like its a hardware problem (since none of the operator's sims tend to work in it while in delhi) and then sometimes it seems to be a network problem (as it seems to work just fine in some areas)
Guys, please.... please help. This is so frustrating.

guys i'm still waiting for a reply.... doesn't anyone here have a solution to my problem?

Install cm7, then full wipe and then install freshly your new rom.
I did that way and after that was network connection back.
Sry my bad english!

Hey this worked but only partially. Now the phone does latch on to network at most places except two: my workplace and home.
And in some places it shows full signal strength but calling is not possible.

[Q] No data and no calls

Randomly I have not been able to text, make calls or get a data connection with my phone. I was running CM 7.0.3 when this all of a sudden started. Restarting my phone would allow me to make calls and get a data connection for a few minutes and then I would not be able to do either. I flashed the newest CM7 nightly build and a new radio, Vision_Radio_12.57.60.25_26.10.04.12. The same problem continued so I flashed Virtuous 2.0.0 but that made no difference.
Anyone have any idea of what I can do to fix this?
Thanks.

I'd say try flashing a different ROM. But since you've fresh flashed the same ROM I'd say that pretty much counts.
Next I'd call the carrier and confirm that you SIM/account is in good standing, and that the towers are working properly in your area. I've had the freakout about "omg my phone is jacked up" and after flashing all kinds of ROMs, radios, etc. I just called T-mobile and they confirm that there was just a network problem in my area.

ur doing a full wipe right?

I actually did flash a different ROM and the issue continued. I'll be contacting Bell to see if maybe it's a service issue.

If you contact bell they'll know that you rooted your phone and they will have less sympathy to help you fix it.

This.

i tell my carrier straight up that im rooted...they dont say anything...but im not calling tech support either

If the OP is just calling to see if their have been any reported service outages or interruptions in his area, whether he is rooted or not shouldn't matter.
A couple times in the past few years, I've had instances where I lost both data and voice service for up to a couple hours at a time, over the course of several days. Then the problem just goes away. This seems to fairly typical, if they are upgrading or repairing your local tower.
If the OP has tried flashing various ROMs, and tried a new radio, I'd be inclined to say the ROM is not the problem. If the problem persists, you may ask your carrier to send a new SIM (or go to their store and ask for one).

hi,
you are not alone!
i have this problem with OE HTC 2.3.3 stock rom! (unrooted original device from Nov. 2010)
so i had very bad mobile connection and after ~1day (without reboot) i can't phone with it.. mobile network only "x" but data connection is fixed to gprs.
very strange!
so i send my phone back and orderd new one.
i think this is was hardware problem.
short:
- reboot bringt full funktion but the mobile connection is not so good as 4month ago (same point).. 4month ago it was "H" and now only gprs
after many hours >8h. calls didn't work, the phone said "no provider"... (x)..
- the strange thing is that data connection is degrade to gprs
this problem exist from the last 2 HTC OTA updates. but onyl the last 2.3.3 makes it really unusable
i hope this problem don't come back with the new desire z now rootet with cm 7.10 rc1 (what a feeling)

[Q] HTC Desire freezes when switching from 3G to 2G

Hello out there,
since I wiped my phone and updated to the most recent CyanogenMod 7 build (#262), my problem regularly freezes when switching from 3G to 2G mode. The only thing to get the device running again is to remove the battery and reinsert it again. If i'm still in an area or room with only 2G coverage, the phone freezes soon after boot-up.
Help or advice would be greatly appreciated!
Thanks in advance,
toco
My phone:
HTC Desire (GSM)
PVT1 S-OFF
RADIO-5.17.05.23
CyanogenMod 7 20120225-NIGHTLY
Android ver. 2.3.7, kernel 2.6.37.6

What I'd do in this order:
1) stop using nightlies
2) change kernel
3) change radio
There was this guy whose phone froze every time he was in space with low or no 3G coverage, and I think changing kernel from snq's to some other solved it for him.

Thanks for your quick response!
Ok, I appreciate your advice. If the problem keeps occurring I will switch back to the latest stable.
But, still something strange about it: I had absolutely no problem the first weeks i was using this nightly (262 was since November 2011 the latest nightly until today), the problem started to occur from one day to the other.
I am using the radio version since probably half a year or even more, without any problems.
Also, 262 was reported (cyanogenmod forums, other forums) to be very stable on the Desire, almost no people reported having problems with it. That's why i decided to update to build 262. I for my part am suspecting a software being the cause for the freezes, but i have no clue which one.. I even checked the system logs.
As for the kernel: Call me a noob, but how do i change the kernel? I know how to root devices, flash recoveries and roms, but how can i change the kernel directly?
Greetings,
toco

Kernel is flashed the same way as roms are. Make sure you use a correct one, manU 2.1 is probably the most popular of those which will work on cyanogenmod.

if that doesn't work:
Dialer/
*#*#4636*#*#
phone settings > network type: WCDMA only

Alright, one more thing: If I change the kernel to let's say Manu 2.1 - how can I switch back to the original CM7 kernel again? Just by reinstalling the CM7 ROM?
Thanks!

Wait, if I set it to WCDMA only I can only access data services when in a 3G covered area, right? Thats not optimal either because i'm regularily visiting my parents on weekends, where only 2G coverage is available. Also in some buildings (esp. cellars) here in the city there is only 2G coverage.

I have done that one month ago and no a SINGLE freeze
I had about 5 a week before
It was mostly difficult on a train trip.
I am a heavy user of those very fast french train and i suffered of freeze about 3 times per trip (3 hours running 300 kmh)
Since the "bending" of sim an sd card = SOLVED !!

Thanks, that seemed to help! Even if i don't get the logic behind that.. but i don't have to, i just want a working phone
Thanks again mate!

There seems to be a lot of people complaining about desire freeze
I thins this should be tried by those since it fixes freeze for me and for you too !!!
Happy this helps you

I am using an other rom, but had the same issues. Problems gone with new kernel.
Droidzones kernel did it 4 me, but i am on a sense 3.5 rom.
Try with uv and other governors too. But i think its a kerne related problem.

3G to 2G freeze - solved
Hi,
I had the same issue: on 3G to 2G network change the phone froze. When moved out of 3G coverage, sometimes during/after the call (probably due to 3G-to-2G handover during the call), seconds after forcing the phone to 'GSM only'. I tried different ROMs, different radios, no success. Finally the guilty component was found: microSD card.
I changed from class 10 to class 4 and suddenly the issue disappeared.
The logic behind this is hard to grasp, but I tried two different ROMs now on a slower card and no freezing for couple of days now.

[Q] COS-Bravo-ICS - problem reconnecting with 2G or 3G after Wifi connection

Hi,
I'm using the COS-Bravo - ICS [21-May-2012] on my phone. Since the first version I flashed I've been having the same problem, but as the ROM is under development, I thought the problem would get fixed in some update. It still hasn't so I'm reporting it.
When loosing a WIFI connection, the phone must switch to a 2G or 3G network. This doesn't happen. Mostly the WIFI icon disappears as it disconnects and the signalstatus doesn't change (no Edge, Gprs or Hdspa is added). When I go to Airplane mode and back or when I switch between 2G/3G, the connection is repaired and the data-connection works again.
I've also noticed this problem with other ICS roms (Sanvold and BCM)
Does anybody have a clue what this could be?

Radio
What radio version do you have?
Its recommended to have the latest radio.
You can find the latest radio here: http://forum.xda-developers.com/showthread.php?t=687464

Of course the latest radio. ;-)

I have the same issue. When turning wifi off, my Desire doesn´t get a mobile connection though it´s showing, that i would be connected.
Switching to 3g and back doesn´t work for me.

Same problem here with Sandvolds ICS
I have this problem nearly 2 years now on every rom (stock eclair, froyo and cm7) and on every radio version, so I guess it is hardware depended.
Correct me if i am wrong.
What I do is switching to airplane mode and back, so i have to enter my PIN again.
Maybe there is a soltution, cause this is really drving me nuts
Thx

With the newest version (01-06-2012) the problem seems to be solved (for me). Perhaps you should give it a try.

I´ve been glad to hasty. It still does not work. Neither does it to switch between 2g and 3g. But the airplane-"hack" does work for me too.

I have same problem with COS ROM. Mobile internet connection after using telephone as wifi modem do'nt working successfully.... i need reboot phone, airplane mode not solving this problem..

Hi!
Same problem here (HTC Desire Bravo, GSM, Cos-Bravo 1st June, latest radio).
This "bug" is present in every ICS Rom and as well in some GB Roms I tried. So far, the RSK ROM Sense 3.5 with amaze cam doesn't have this issue.
I hope someone will get to it. I'm more than ready to donate if someone will be able to solve this out with next build.
Thanks.

To judge from my own experience - I'm still seeing this problem six months later - it has not been fixed yet. Or does it only affect a subset of Desires?
I'm experiencing it using a GB ROM - Mildwild 4.7, though it was there in 4.6 as well. I can only assume it is in the ROMs, as I get it on two different handsets, a PVT3 running radio-5.17.05.23 and a PVT1 rrunning radio-5.11.05.27.

Remove the skipbrokendatacall entry in build.prop file. This will not completely resolve the problem but will make it very much manageable.

Check your APN Settings and try to set APN-Type to default only.

[Q] HTC One V - Problems with 3G connection :(

Hi there,
my girlfriend has some problems with the 3G connection of her HTC One V, hopefully one of you can help us
She´s using an o2 simcard in her One V. If the One V is powered on for some hours/mintues at a time it happens that the 3G connection isn´t working any longer?
You can still see the H(SDPA) / E(DGE) symbol in the topbar, but nothing is working?
If she turns off and on her mobile connection, nothing happens.... 3G is still not working.
The only way to get the 3G connection working again is to turn the flight mode on and off again. After that everything is working as usual.
(A reboot is also working)
As I got my HTC Desire 2 1/2 years ago I had the same problem,... after an android update everything was working as it should.
But these 3G problems are really quite annoying
Is there anybody out there who has (had) the same problems?
She´s using the HTC stock android 4.0.
Hopefully it´s not a hardware defect
Thanks for your answers so far.

that´s not so easy because she has a contract with o2 ...
I don´t believe that this is a hardware error, because after booking in into the cellphone network everything works as it should... but then after some time it suddenly happens that the 3G network is dead

i have to ask, but is the back cover on?

of course, back cover is on. I also don´t think that this has something to do with the back cover (or any other hardware) because like i just said after switching the flightmode on and off everything works as it should ... i´ve googled in the meantime and I found some other people who are also on android devices and they´re having the same problem.
here´s a german article of people who´re having the same problem

Its not gsm, right?? You can't get a sim from somewhere , out it temporarily and try?
Sent from my One V using xda app-developers app

it´s a GSM smartphone...
well, actually i have no chance to try another simcard in the phone...

Moved to Q&A. Please ask all questions there.

Could it be possible that the problem is due to the baseband version her One V is using?
If I remember right i´ve upgraded the radio rom, too when i was flashing my Desire 2 years ago. After the whole flashing procedure the error was gone?

I had the same problem. REBOOT and it worked again

have you try using another carrier? or is your phone primo c?

If the phone is locked to a carrier he can't use another sim to get service I think he's trying to say, so sim from another carrier is out of the question.

the phone isn´t locked to the carrier, but i don´t want to buy a new simcard just to make sure if the phone is working correctly. I´ve already thought about installing a custom rom.
Can anyone advise a good custom rom for One V which is working correctly with all functions? (Maybe a Jellybean Rom?)
Thanks so far!

Are you sure HSDPA means falling back? Imho it's only a type of 3G and it is really fine if you see H for mobile data mode. I might be wrong or this might be treated differently by country/operator.
