Problem with signal loss and sync.

Hello,
Today I ran into a new problem, that I have been trying to figure out for hours, but couldn't find a solution.
I have a T-Mobile Touch Pro 2, sim unlocked-security unlocked, and hardSPLed.
While device is on, the signal suddenly drops off, like as if it's re-starting the radio, and then gets the signal back in 2-3 seconds.
Whenever this happens the activesync connection also gets interrupted, WMDC says device is disconnected, while the TP2 still thinks it's syncing.
I would appreciate any suggestion, and solution, or at least any idea about why this could be happening.
What I tried so far to solve the problem:
1-I hard-reseted the device. Not even sure how many times.
2-Tried with different stock ROMs, WM 6.5 Europe, WM 6.5 T-Mobile.
3-Tried flashing a few Radio ROMs.
4-Tried setting the device to chose only GSM, and GSM900/1800 manually.
So far, I started focusing on the SIM card. The only thing that changed since Saturday, is the SIM card, as I changed providers, but it's still awkward that the problem started just today.
Thank you.
New Symptom : After losing signal, sometimes it can't connect back to network, and asks for PIN again. happened twice so far.

Update: Ok, the problem is beyond SIM card, since I just removed the SIM card, and decided to see, what happens when I try to Sync.
The device continues to do hiccups, the USB connection drops on computer side, even though device doesn't recognize that, and device asks for a SIM PIN, as if I just booted it.
Any help would really be appreciated at this point, since I'm out of ideas about what to do.
And no, warranty isn't an option for me, since it's a US device, and I'm not living in the US =(

So, I flashed back to 6.1 stock TMOUS ROM, problem still there, went to 6.5 TMOUS, problem is still valid.
Can't seem to figure out any solution for the night, and calling it a day. Suggestions are more then appreciated =) Thank you.

Well, I need to bump this thread, as the problem is still there, with no solution, but it just metamorphed into something else.
I asked for a solution from HTC, but all they said was to try with another operator SIM, which didn't help of course.
But after countless hard-resets and flashing, now the connection can keep up for a few more minutes.(sometimes around an hour, but usually good enough to finish up a 15 min sync)
But, now after coming off the suspend mode, it sometimes give me a "A problem with device.exe occured" error, and after I get that error, I lose voice in calls. (As in, I can recieve calls, or make calls, but in both cases, can't hear the other side, and they can't hear me either)
So, what could possibly be the reason for device.exe error? I heard that some companies, just change devices that gets the error, but it's pretty impossible for my device to changed. (=> TMOUS Rhodium user in Turkey)
So any ideas, or solutions? Or anything you want me to try? I'm pretty open to do anything at this moment, since If I can't solve the problem the device will turn into a 600$ paperweight. And an ugly one too, for the price =p

Just another symptom:
Before all these started in the WMDC, no matter what ROM was on the device, the device picture would be a T-Mobile TP2.
But now, on WMDC, picture of the device is an unbranded HTC TP2.
Today, hoping to be able to turn everything back to the beginning, I flashed WM 6.1 TMOUS ROM, and re-flashed the stock SPL. After connecting the device to WMDC, the picture was still an unbranded TP2 picture.
The problem of hiccups with network signal came back with the stock ROM, and is driving me crazy.
And, I decided to flash the leaked TMOUS 6.5 ROM, which didn't help anything at all. (The picture isn't a TMobile one still)
So, I'm thnking that the flashing progress, at one point just fiddled with a part, that we don't know about yet, which contains device information.
Anyone with any ideas? =I

Try flashing a different radio to the phone. Nearly all cooked roms wont come with a radio. If it is an official stock rom that you are flashing they normally have Rom, Radio and Splash. If you put the rom on your sd card and try to flash from there what does it say when the grey screen comes up and tells you what is in the .nbh file?
Also i hard reset before and after flashing, especially after seems to help.
Could be faulty phone if you have tried other providers sims and its the same.

Network connection drops out intermittent after gfree

So I just did gfree earlier today and everything went fine, at least at the time.
I did ./gfree -f so I got s-off, sim unlock, and supercid
In the past couple of hours, my connection has been really sporadic. I go from full bars, to no service for no reason. I'm at my house, and I have never had these problems before.
I'm assuming something went wrong in the gfree process. Maybe the sim unlock? Is there anyway to revert the unlock to see if that fixes my problem?
I read the wiki and I saw how you can reset the supercid and the s-off to s-on, but I don't see anything about the simunlock.
Any help or insight on this problem is greatly, greatly appreciated.

Well, it seems that my problem has fixed itself, sorta. I switched out sims with my brother's phone to see if maybe my sim was bad, and low and behold the phone got a signal again. So, I put my sim back in my phone, and for some reason, I started getting a signal again. Don't really know how to explain that one, but I'm glad it is working again.
Could this be a precursor that my sim is going bad? I kinda had an idea that it was already going south a while back when I had it on my old android phone and in the settings>about phone>status it said that my phone number was unknown and this causes my picture in the contacts and messenging app to be a gray box.
I don't really know what went on with it, but I haven't had a problem since. Maybe it was a glitch in the matrix?
What do you guys think?

Blow on it like a nintendo cart
Actually cleaning the SIM contacts with something like a pencil eraser usually works wonders.

I don't think it's anything to do with gfree. Could be the SIM. Or even the way you are holding the phone. Sometimes the way you hold the bottom part of the phone can affect the signal, since that's where the antenna is.
You could also try upgrading the radio - see the radio thread on that.

I took a look at the thread and I have 26.03.02.26, the 26.04.02.17 radio being the only one that supersedes it. I got to thinking though. My reception was fine before and I had no signal even when I was not even holding the phone. I see no need in updating the radio since it seems to have fixed itself and has not happened since.
Only problem that I would like to fix now is the phone not recognizing my number in the settings, causing my contact picture to be grayed out.
It's strange though, because, my phone will pick up another sims number if I install it, and even weirder is that if I install my sim into another phone, that phone picks up my number.
Not really sure what I need to do to fix this.

GSM not working anymore, stuck in emergency mode

Hello all,
my Defy is stuck in emergency mode and can't find my carrier anymore (o2). Details:
- only emergency calls possible, no network found
- another mobile in my house gets outstanding connection (o2 aswell), when switching SIMs, it's still my Defy not getting a connection
- wiping the Defy has not changed anything, even with stock settings all I see is the red cross (put my settings back with clockwork recovery)
- an hour or two before this happened I was listening to music with my headphones, but between taking the headphones out and GSM failing I was sending texts
- When doing a search for other carriers I can see some (though not reliably), but not mine
- I bought my Defy via Amazon, so no SIMlock, obviously.
- WiFi, Bluetooth and GPS are all working fine, so they probably have different antennae
- I rooted my Defy, but this was over a month ago, and it was working fine. I also did not install apps or update some existing ones before this happened. I also did not reboot. It just happened. Put it in my pocket and next time I got it out there was the red cross.
In Phone Info -> Status it says under signal strength "-111 dBm 1APU". It all looks like the antenna is broken, but I didn't hit it, drop it, put it into water or hurt it in any way before this happened or the 3-4 days before. So I'm really lost here.
Anyone? Thanks in advance.

Hi. Have the defy for about a month now. Same issue since first day. Dont know whats wrong. Found out that after 4-5 reboots its ok and lasts till next reboot/switch off. So try turn it on/off 4-5 time or just download a quick reboot app and do the same to see what happens. If aneyone has any idea on how to fix this?

i get this all the time when i flash my defy thru any other rom......and thus roll back every time to stock (indian) rom.....
try flashing your phone with any compatible rom....new radios might get ure phone working

Same problem here. First time today, spontaneous, after a month of use my Defy, non rooted, never unlocked, standard noMOTOBLUR, just like as it was bought from store. Moto_Versiuo.2.34.1.MB525.Retail.en.SEA
None of these worked to restablish the radio connection: succesive reboot, manual/automatic network search and choose, succesive airplane on/off. I didn't check the signal parameters.
I thought that the SIM just burned, removed and try it on another phone and everything was OK. When put it back in Defy, the network connection was established.
The experience was very strange and my final verdict was that the SIM just moved a little from its initial position.
BUT now I realize the problem is more complex and I don't know what caused it !

I have also noticed that the sim card slot gives a little more space for the simcard to move (at least on my defy). Might be a prob with the sim card being old or something (mine is from 2005). For now i'll just try to keep my phone on (seems i finally found stable settings for setvsel, so no more unexpected reboots).
An answer from motorola's official support forum is just remove the simcard and clean it with some cloth...

This is definitely a sim slot/card problem. If bought from amazon they will oblige to change it without any money. I did the same but not for this problem.
If you think there is some problem with software, which is unlikely then flash an sbf and see if things are fine.
To begin with flash chinese froyo sbf. It is downgradable to any previous firmware you were using and very flexible.
Hope this can solve your problem. Get back on what the result is.

Same here...
My defy got network yesterday at 07pm til mid-night.
before, since 16 (11pm) til 19 (7pm) before it function again.
and now, its bloked.
i rooted my cell one month ago, then, probably thats not the fault of z4root.
Sorry about my badass english, i still in upgrade mode.
any idea about it guys ?
thnx

Problem solved replacing sim card with a new.

[Q] suddenly can't see any mobile networks - Baseband "unknown"

SYMPTOM: can't see any mobile networks
BACKGROUND: I've been using htc one x for a month now. Initially on three, but their signal was unusable at home, so sim-unlocked and switched a couple of weeks ago to giffgaff ( a virtual network on top of the UK o2 network).
All has been fine, until today. I sent a few texts & calls in the morning, and mobile data was working. Since then, I can't see any mobile network.
wifi is fine.
Search Networks pops up "Error while searching for networks" and finds none.
No software changes of any sort since last successful call. No changes at all today, at least until I tried to diagnose the problem.
Running stock rom, with the WW update of a couple of weeks ago (1.28.771.9.CL56522 release-keys) -- neither S-OFF nor unlocked bootloader.
Nothing obvious to me in the normal or radio logcat logs.
The only thing I did after the last successful call was to run sensorly to try and map a trip. I've used this before without any problems. It got no connection but I thought nothing of that. I've since uninstalled it just in case it could somehow be interfering with the radio.
THINGS I'VE TRIED:
No, the airplane mode isn't on, and mobile is. I've toggled airplane from settings and power switch, many times
recreated the APN
checked other phones - yes there are a number of networks visible
tried the original o2 sim - same problem
safe mode
cold boot
reboot, reboot, reboot
obviously I haven't pulled the battery...
turned off wifi, in case it was somehow interfering
HTC diagnostic tool
factory reset
confirmed imei is not blocked
Any ideas? Bearing in mind that I'm looking for something which can happen spontaneously.
Interestingly, while writing this I've just noticed that Baseband version shows as Unknown. That worries me - is it possible that my radio partition has spontaneously corrupted itself?
I did speak to 02 support - they said to take it into a shop for warranty repair. I don't want to try a custom ROM just yet -- not when I might have to use the warranty. But is there any way to force it to reinstall the stock rom (preferably not involving windows)?

I have the same problem as well and flashing custom roms did not solve it for me. But for me even the IMEI number is shown as UNKNOWN...I haven't done anything special to get this issue, one day when I woke up the phone could not connect to any network.
I have tried a lot of different methods but with no success. I don't think we can do anything about the baseband without S-OFF.

If a hard reset fails, then it's time to think about returning the unit. Either get a refund or get it replaced.

This may be irrelevant; but I've had this happen to me on my GNexus. I solved it by going back to stock and it just fixed itself overnight.....

my HTC One X did the same after about 2 weeks. Gave it back to supplier, waiting my replacement.
Even tested with a different SIM card, did a hard reset. Problem stayed the same.

Im curious did any of you find a resolution to this? it happened to me a while ago but yet to fing a solution. HTC refuse to fix under warranty because it is unlocked.. i am currently waiting for the next official update to see if that fixes anything but the way things are looking that could be a while..

It sounds like a fault, probably the radio chip has just stopped working, no software is going to repair that. If it was a software problem, there would be hundreds or thousands of people all having the same issue.

OTA update and factory reset - Lost mobile connection! HELP!

Hi all,
having had the malware come through in the recent OTA update, I decided to do a factory reset to get all my data off quickly before any of it went to someone it shouldn't. Before the OTA the phone was working perfectly!
Unfortunately, after that, I have not been able to get connected to 3 Mobile (UK) although it worked before. I get the "Can't connect to this network right now. Try again later." message.
I've flashed a variety of ROMS, from old stock, to new stock, to Eragon.....none of which allow me to get on my network.
Wifi works fine.
The IMEI did disappear, but I was able to follow instructions online and manually reinsert them successfully.
I wonder if I have somehow knocked out the RF frequencies as I did not know I needed to make a backup of these.
ANY help you can give me to rescue what is a pretty decent phone (let down by Elephone's software!) would be great.
Thanks!

I have never had this problem thankfully so I am not sure what you should do but the video in the link below may help?

Some progress - oddly enough I tried restoring the IMEI numbers to the opposite SIM sockets and now the RADIO setting declares that it is on.
I think this is because it is a very early version of the phone and perhaps the SIM labelling was the wrong way round. Who knows.
I've attached some screenshots of what seems to be going on right now. Any ideas? Anyone?

I can get the phone to connect to 4g, but it will not connect to 3g/2g.
What do I do now?

Glad you have managed to sort of sort it. For 3g have you selected that in mobile data settings?

It was a hardware issue - opened the phone up and the antenna connector had come away from the motherboard. Must have happened when in my missus' handbag (her phone - not mine!).
All solved now.
Might be worth others checking their antenna if having the same issues. Under the plastic cover is a little rubber 'knob' which puts pressure on the connection. I don't think the back was screwed down hard enough to keep the correct pressure on the connector.
