No signal - Reflashed 3 times

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

[Q] G2X 4G Problems

I've had this phone since release and have loved it. I have only one issue with it. I'll be trying to use my internet on the phone and it will show the upload arrow but the download will never do anything. I have full signal so this is not the problem. This happends a lot and in the middle of browsing it will do it... It will load a page and I'll click a link and it wont load and then it will work again after awhile. Does anyone else have this problem? Does anyone know a fix or the reason its doing this. Also I have full 4G coverage where I am.

It happens to me a lot too! Its very inconvenient and I know its not the area where I reside because I also have a g2 on my spare line and the g2s data works perfectly fine when the g2xs is stalling. :/

Did you get yours at release? If so it may just be the first batch or something...

Could be lots of things. Have you activated and are using the SIM that came with the phone. Supposedly the G2x uses a new SIM format.
What OS are you running? Are you on WiFi? 2G, 3G, 4G? Where does this occur?
I surf my with my phone a lot and I don't get that intermittent data problem you are describing. I am running the latest CM7 (#70) and in a 3G area with average signal quality.

I'm using the SIM that came with the phone and this is only on 4G I reverted back to stock ROM unrooted and still has the problem

I've never rooted my phone. I've actually swapped the sim twice already thinking it was the problem. Hard reset has been done. I've pretty much tried every trick in the book and the problem still persists. Its my 2nd replacement(1st one had the same issue)

P.s I got the first one at release then had it exchanged(buyers remorse period) for a new one towards the end of may so I doubt the 2nd one was from the first batch.

Like Player said, could be alot of things. For a sim, the G2x does not require a brand new sim, but it does require a newer sim. If your sim is older than 18 months, put in the one that came with the phone. Last years TMOBILE sim will work with the G2x.
Also, data plan. Didn't happen to me, but did happen to my son, the plan was not enabled for 4g Android. He got signal, rarely 4g...but did get 2g.3g. Walked back in the store..asked what was up...they checked...1 mouse click and finished. Funny thing was, he bought the phone from them, earlier in the day. You would have thought they would have covered that.

Your sons phone was showing 3g? Hmm... I thought on tmo 4g was a fast version of 3g and that the g2x only showed 2g or 4g. I am probably misunderstanding something.

So I went to T-Mobile just now and they gave me a new SIM and it fixed all the problems so if anyone else is having trouble try getting a new SIM first....its free

[Q] No Signal. Limited Service. --- HTC Sensation

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

So frustrated, about to return One X but seeking advice

All,
I have had the One X for just over a week now. Three times, I have had to hard reset the phone because it stops receiving / making calls, and data stops.
I tried searching the forums but it seems like issues are all over the board and couldn't really find something that was exactly my issue. If there is one, I apologize for the duplicate post.
Regardless, when the phone is in this state, it appears like everything is working. It shows I have great signal, the little 4G icon is there, indicating that everything is working.
Anyone else have this problem or could I possibly just have a bad unit? AT&T already swapped out the SIM card thinking that might fix it, but no luck.

I think you should swap out the phone as bad before returning it if that's the only issue you're having. mine seems flawless in that regard. I haven't missed or dropped a single call.

Thanks for the suggestion, I'll give that a go.

Definitely return it for new one...that problem is one I have not heard of and will probably go away once you have the new one. Good luck...badass phone for sure.

I don't recall ever having that problem. Mine was pretty random too, in fact it got so bad yesterday that I missed several important calls.
If I would restart the phone, I would get all my missed text messages and the voicemail (google voice) would tell me I have messages waiting..
Very frustrating.

I thought that might be my problem too, but where I could stand in one place and have the problem, restart the phone, and then not have the problem -- that leads me to believe there was something wrong with the phone.

Nope the wife's inspire stayed on hspa

My X started out ok, but these last couple of days I have NO signal anywhere. Also SMS/MMS is barely working. (and when it does, people are getting multiples) And its dropping pretty much every single call.
I just called my corp store, they have plenty in stock. I'm going to go exchange it. Should I ask for a new SIM also?
And my screen is perfect, here's hoping I get another good one...

However, AT&T's LTE phones are notorious for connection problems on non-LTE market. These LTE phones use a new APN called pta. I just had the same problem while traveling through PA yesterday. Lost data connections many times and had to reboot the phone at the end of the day to regain data connection of any kind.
So, it is AT&T's service and also the phone firmware that can't properly handle the fact that it can't receive any LTE signal in certain areas.

return it and get another phone, besides the One X, it's all hype anyway. The HTC vivid is a much more solid phone.

I had almost the same issue. My device was on wifi and would at random times just stop pulling data. Or at time just not make calls. I tried trouble shooting it but I was basically told since I didn't have it long I should get it replaced. I replaced it and the new device is perfect. I have not once had that issue again.

Who said I'm going to reture it. OneX, regardless all its problems is still way better than any alternatives AT&T have. There is no such thing as problem free Android phones. I've being many of them. They all have problems one way or another. Vivid with its ancient S3 CPU and SD screen just plain sucked. My SGS2 can kick its butt.
For me the form factor of One X, LTE speed, S4 processor and HD screen are the main things I pick One X over any other phones available on AT&T. These software bugs will be corrected overtime.

I just came back from my store. They had plenty in stock but said when that runs out, they have no idea when they will see anymore.
I have a brand new 1X, and a new SIM card. Hopefully this one works.

I stopped by a vzw store to look at the gnex and my hox side by side. I've decided to keep the HOX. Screen on the gnex was way too bright and I ran quadrant side by side on both phones. The hox blew the gnex out of the water.

Bought mine yesterday and this same issue happened to me today. Had full reception on 4G but could not send a text or place a call. Happened twice today, and I dont know if I want to return it ASAP or if its software related and may be fixed.

I had that problem 3 days after buying the phone. Data, calls, texts..tons of problems. Phone was unusable half the time. I went and exchanged it for another one. I am now at 6 days with the new phone. No problems. I hope it lasts.

4G Data Drops

I finally got someone at Verizon to admit that the 4G dropping issue is at the top of the known issue list. Each time I have gone in the store I have been met with 'surprise' that this is an issue. Invariably they have tried to replace my SIM card or phone none of which has worked. The notes on this issue that the phone support person had were rather disturbing.
The first one indicated that this was a known, accepted issue and that the phone was working as intended. Ack!
The second note said that the vendor was working on the issue...IE HTC.
So...onto HTC I go...
The HTC rep also admitted knowing about the problem. He said they were working on a software update to correct this. This of course led to discussion about ICS. According to the HTC rep I spoke with the update has NOT officially been cancelled at this point. He could not say whether or not the fix for the 4G drops they were working involved ICS, but did seem to indicate it might. As usual no remote ETA as to the fix.
Truthfully I could care less about ICS...I would just to have dependable 4G that didn't drop every time I try to use GPS to get home from work, stream music for my kids, or check Facebook.

I just got a new sim and so far so good. What rom and radio are you on? Radio's tend to be a big factor in data dropping.

Yeah if I run twisted build my 4g will drop but if I use let's say skyraider I have no data drops where ever I go. Many times you need to find the right radio for the rom you use.
Sent from my ThunderBolt using Tapatalk 2

Well...I have tried the .19, the .9 and the leaked ICS radios when I tried the ICS builds. I actually don't know about the leaked radios as I had too many other issues with ICS at this point for me to use regularly...but the .9 and the .19 both give me pretty regular 4G drops. I just dropped back to the .3 radio this morning to see if that helps.
Thanks for chiming in. Maybe I should try another SIM card...only replaced that once...have replaced the phone 3 times now. I spoke with Verizon AGAIN yesterday and was basically told what did I expect with a two year old phone. I guess they expect you to have to buy a new phone every two years to keep them working. Freaking consumer society.

A level 2 tech told me that the drops are also related to the fact that the 4g network isn't fully implemented. What we get most the time is a 4g extension that was put in place to expand the network faster. They also told me that the parts of the network that are a 4g extension get only half the speed of a fully implemented area. The suggestion I was given was just disable 4g when I'm in areas that have spotty coverage which actually helps. The problem seems to show itself on the hand off between 3g and 4g. Almost like the phone gets confused on which network it should be on.

I think I am in a crappy 4g zone. But now you make me wonder about that...

I'm in an area with solid 4G coverage (I use an LG Revolution). I just installed a ROM on my brother's Thunderbolt for the first time last night, largely prompted by his phone being stuck on 1X regardless of where he is. Sadly, it didn't seem to help, even with trying to flash a few radios. His friend also has a Thunderbolt, and his has no connection problems in the same area. Who knows.
