Today my phone has been switching from no signal to signal
and now it refuses to get any signal
i have tried changing the radio
reflashed stock rom
then reflashed a modded rom
and each one has the same result ...
any other ideas what could be wrong?
i get signal if i put the sim in another phone
so its definately phone related
make sure the radio matches the rilphone.dll?
yep
same .dll from the radio package
have a feeling its some internal problem
cuz the sim is fine otherwise
grr
What about Edge?
I had a LOT of frustrations with mine a couple of weeks ago, then, just to play a hunch, I disabled 3G, and went back to edge and it worked perfectly. Sent an email to the deathstar, and they sent back saying they were having 3G problems. Reading over on boygeniusreport.com, a LOT of people are having trouble with 3G. At&t doesn't have the bandwith to support all the apple iPhone fanboys I guess.
Probably not what's causing your issue, but might be worth a try...save you from pulling your hair out.

If this doesn't help, disabling 3G, you may have to do a warranty exchange.
left battery out all night (last night)
then i reconneced it this morning
and everything seems to working fine
must have been some internal static
thanks dudes
Ok. So I ran into a serious issue and it most likely has something to do with the 3G radio.
Here's what happened. Phone was down to about 15% batteries after some Youtube and Angry birds. I was at my folks place and the cell signal there is not as strong, but still a bar showing. I noticed the phone was quite warm, but thought nothing of it since I was using Youtube/Angry birds. Check a few emails and noticed the batters quickly dropping to 12% within a few minutes and noticed Battery Status Monitor was reporting 990mA draw. I was alarmed, but didn't think too much about it and went to have dinner with the folks.
about 30/40 min later after dinner. The battery was dead. Didn't have my charger with me, so I didn't plug in for another couple of hours until I got home. Plugged in, booted up, everything was fine, except it would not connect to cell service stating "No Service". I then tried a bunch of things, rebooting, swapping out the battery, swapping out the SIM, but no avail. Swapping the same SIM to my old HTC works fine and connects on AWS 3G network.
This morning I tried another SIM that not on AWS, and it connects (assuming on 2G/EDGE network). Swap back in my original SIM and back to "No Service" (my provider only has 3G AWS service).
So at this point, I'm pretty convinced I have a hardware problem so I restore the stock Froyo ROM to return my phone...then magically, I'm back alive on the 3G AWS network!
Someone tell me what's going on!
I haven't tried to reflash CM7 again. Quite frankly I'm quite scared this may not be hardware problem and maybe a software issue instead, and may be stressing the 3G radio.
Help!
First, not to be rude, but this isn't development.
Secondly, what carrier are you using that only has 3G service and nothing else?
To me it sounds like your SIM card could just be shot, especially if you were able to insert another and it worked just fine.
Then again, that's hard to determine if your carrier actually only offers 3G service.
wrong section and a hard reboot always works ! volume up and power down hold for 10 seconds until u see lg

How do I move this thread?
My original SIM is fine. It works fine on my HTC in 3G. The other SIM is with another carrier that's NOT on AWS spectrum and my G2X connected in 2G only. I'm in Canada, our new carriers Wind, Mobilicity, Public, etc are on 3G+ AWS only with no 2G fallback. I can restore my CM7 and try a hard reset if it doesn't come up. But I'm just concern, there's a software issue that cause this failure.

I had just flashed the newest CM7 Nightly and noticed when I woke up in the morning, my SIM wasn't being read. I wiped, re-flahsed, no workie. I tried a hard reboot, nothing. I even flashed to build 90 and still didn't read my SIM.
I'm loading xhoarder's tweaked GB right now...and it STILL isn't reading my SIM!!! What the hell happened?

Mine stopped working after a couple of days. I'm back on stock Froyo and it's working again. Did it work at all for you with the latest CM7 nightly?

It worked while I set everything up and loaded my apps. Went to bed, and when I woke up, the SIM wasn't detected. I'm on xhoarder's tweaked GB ROM and my SIM still isn't working.
Going to try a hard reboot.
Whythis is here?. There is a Q&A forum exclusively for questions.

Hello people! I am a newbie on Android, so don't expect me to know deep stuff about Android.
So, I've been using HTC Sensation for about a month now. I've been using it without problem, but suddenly on one night, hard rain strike Bangkok. Suddenly, my phone goes no signal and limited service. I thought it was some some problem, so I wait for a while in order to get the signal back. About 20 mins later, my signal bar is back, but still no Mobile Connection icon (e.g. H or 3G). The worse thing is even though my signal bar is back, I still can't make/receive any calls or sms to/from anyone. I thought it might be some problems with the towers, however, when I switch my SIM to my mom's iPhone, the signal appear to work and the connection worked without problem.
That's when I thought its the problem with the phone. But... when I went out of my area (house), signal appear to work with 3G and I can perfectly make calls or texts without problem. When I got home, No Signal once again. So now I don't really know if its the problem with the network or the phone...
This really annoys me as heck. If someone can give me advices, I will be much appreciate. Thank you very much
My phone goes from having full bars on 4g to nothing randomly me having to pop out the battery to get service again.
Tired of the same
http://forum.xda-developers.com/showthread.php?t=1098849
i decided to make the jump and my issues went away, i would have preferred to remain stock however i don't like to be branded, stuck with bloatware etc..
thank you and all of you reply this thread. I am very new to Android, so I'm not really sure about 'rooting'. So Lostcat, you have this issue? and your issue went away after you've rooted your phone? Also, if I am going to root my phone, will all my data, contact, apps, and setting gone? If yes, anyway to do easy back up?
Thanks
I was having similar issues so I sent mine off for repair (through carphone - they say they send htc phones off to the manufacturer but considering its only been a week and they have reapired it i doubt that it has been sent off) still im sort of glad it didn't go off http://www.bbc.co.uk/blogs/watchdog/2011/10/htc_phones.html - im going to get it this afternoon. will report back with findings

You have answered your question yourself here.
It's clearly a problem with your local cell since that night with the hard rain, since when you go to a different area your phone works fine. Contact your network and report theres a problem with your local cell.
cheers
Are you sure? Why does he have a signal in his mum's iCrap?

Yeah, at first I thought its the signal problem too. But when I switched SIM and put it in my mom's iPhone, it work. And I use her SIM on my phone, and it worked too! Pretty confusing eh?
Alright.... I've decided to give my phone to the HTC support to fix it after I've asked a lot of people and they said its the antennas problem. Anyway, since I phone is rooted, in order to give to support, I need to unroot it.
I know people posted a lot of steps on unrooting HTC Sensation, but I want ONE SPECIFIC SAFE and SURE steps for unrooting... Thank you
Hello,
I bought my Nexus 5 on the 11th of December 2013 and it had been working flawlessly ever since. Since last week, I started noticing the occasional signal drop and I'd be out of cell reception but would usually be back up within no time. However, yesterday, out of the blue I'm travelling on the highway and my signal strength disappears never to come back again. I've tried the following:
- Restore old backup (including EFS)
- Went back to stock from PA
- Upgraded to the latest radio
- Took back cover off to see if anything was wrong but found nothing.
- Tried another SIM card
Nothing worked. My SIM card works fine in another phone. Everything else such as WiFi and Bluetooth works flawlessly but I just don't get any reception.
This is very disappointing and I have my fingers crossed hoping someone can help me with this since I didn't plan on getting a new device for at least another year especially after paying $520 USD for my phone here in my country.
Thank you for looking.
im having a similar problem with the radio after the last few otas. im getting a lot of dropped calls on 3g aws...
im going to try to revert to an old radio as i don't think this is a hardware failing issue..
Sent from my Nexus 7 using Tapatalk
Flash stock firmware with fast boot. If its the same, its a carrier issue....call them to see. Or its hardware failure.
just wanted to post my fix for this issue - very disappointed with Google that i had to do this...my provider is mobilicity canada (3g aws band fyi)
flash krt01b radio from this thread...
http://forum.xda-developers.com/showthread.php?t=2514095
this is *not* a carrier or hardware issue (at least in my case)
seems others are having same issue
https://code.google.com/p/android/i...s Owner Summary Stars&groupby=&sort=&id=70878
Then it is a carrier issue....cause on Telus in Canada....never had an issue with any radio version. ?
telus would have a stronger overall signal but uses AWS band for lte which is different than mobilicitiy 3g aws...
I'm not disagreeing.... Just saying its the carrier....not Google.
See my point?

are you saying mobilicitiy is purposely weakening their cell signal cause they are almost bankrupt ?
i still blame google i had no issues with the radio before they borked it...

Just saying that unless many have the issue with the phone or radio, then its an issue.....if not, it isnt .
So in this case, it leaves hardware or carrier....assuming a stock flash didn't help.
If flashing another radio helps the OP...awesome!! But the new radio does work fine for the mass majority.
Hope it does work for him tho!
Hi all,
I've had this great phone MT7-L09 (softare version L09V100R001C00B127) since last December. My problem is that every now and then the 4g cuts off for a period of ten seconds.
It does not matter how strong the signal is nor which or whatever app I'm using. It just loses network. First thing I did was to change the old sim card to a new one. Did not help.
I was in contact with the Huawei support and conclusion was to send phone to service. OK. It came back with the same problem altough they changed the circuit board...so obviously they though that this would solve the problem. I did not. After messing around with it, trying to find if someone else was suffering with the same problem, with no luck, I send it back to service. Now they said that there is nothing wrong with it, but the problem is still there.
I havent noticed anything cut offs using 3g. It's not a major thing but it would be nice to know if its a firmware or any other software related problem.
If I use Netflix or similar where the data keeps coming it works just fine or if I use the phone as Wi-Fi hotspot, no problems.
It just loses network connection using apps like play store, facebook, whatsapp, twitter, every browser ie. firefox, build in browser, chrome, to name a few.
Should I just keep using it as it is or keep sending it back to service until they fix this issue???
Thanks

Sorry...one stupid question: have you already tried keeping the phone completely stock (without any application and/or software or any kin dof personalisation) for a couple of week and see if the problem still exists?
It really seems to me a software problem. Very strange.
I had the same problem with my MT7-TL10 golden version. For a week or so, the network used to come and go. Then ultimately the sim was not recognized at all. I sent it to Huawei service center and they told me that the sim slot is broken and I had to pay for replacement of the board which I refused. I was sure that I didn't break it. Now I am using my phone with one sim only.

I haven't used it only with stock apps for a week maybe a day, but first thing when it came back from service for the first time, I did not install any apps and it still lost the connection anyway...

I'm not sure, but isn't the sim card slot located on the circuit board??? If it is, it cannot be the problem, but I must try the second slot anyhow.

Man why everybody blames PHONE first??? like not trusting !
To fix this problem is to go to networks and u have to restore your apn to default it like refreshes then you can either just turn off data and then on and restart phone

Does not work, same problem after a numerous resettings. If I may add, I've have couple of other phones of which this problem does not occur.
In same place and conditions these phones work just fine not losing the data connection. Sure, if 4g is not available they use 3g, but never ever will the connection break off.

faulty 4G module tuner.. phone ... replacement needed...
change preferred network
Go to settings and -->mobile networks-->>preferred network and select "WCDMA only"..
It will fix your problem..
There is no such option in my phone settings, only the option to choose automatic 4g3g2g or automatic 3g2g or 2g, 3g only and 2g only. As previously stated no data loss nor connectivity issues using 3g. It's bit annoying sometimes when phone loses data connection altogether although signal is very strong. Just waiting lollipop upgrade if it'd solve the problem, I doubt it but...
network operator..
I think it's network problem..please contact your network operator..4g network have connection problem from some local area signal towers..so you just put other network company SIM card in your local area..(use 4g supported SIM only)
Thanks for your advice, but I don't think that it's SIM card problem because there is no problem what so ever using my other phone SGS5.
sorry

Hmmm. Sorry friend..I am helpless.. anyway continue your thread here..in Xda have brilliant members..they can help you..best of luck.
Thanks, I totally missed your comment...this is turning out to be quite a puzzle. I've noticed the less battery (<60%) I've have on the phone there seems to be nothing wrong with the 4g connection. ???
To answer to myself, I was too optimistic...nothing to do with battery. It's just so weird that phone works like a charm most of time and then suddenly not. I'm confused...
Now on the newest firmware lollipop 5.1 it fixed my lte problem
same issue
I bought mate 7 a couple of days ago and I keep losing the data connection. the network gets connected and lost again.
i did everything to fix it but no luck. changed sim, restored device, modified APN and no luck.
it keeps disconnecting seems that it is a problem with the phone itself as i have read the same issue on a couple of forums..
hope it is a software issue and get fixed soon as this is annoying.
In service they replaced my phone to a new one mostly because of this problem and I can say it did not help at all. Only upgrading to lollipop will fix the problem ( tested on beta) I'm on b145 now and it does that all the time. I guess it is carrier based problem not SIM nor hardware.
