Tilt: lost signal never recovers

Folks,
(I've searched around a bit and seen some reference to this problem but no definitive discussion. I apologize in advance if I missed anything and humbly request a pointer to the existing info if so.)
Just got a Tilt last weekend. On 3 occasions so far I looked at the screen and noticed that the phone had no signal (triangle with ! next to it). So for several hours each time, no one could call me. Going into comm mgr, the phone radio was still on.
This was in an area with no signal problems; soft reset or pulsing the phone radio in comm mgr would restore functionality with 3-4 bars. I finally nailed this down to having been in an area in the center of the building where I work, where signal gets lost. It appears that my Tilt never automatically recovers from a lost signal.
I saw this problem on the ROMs that came with the device and now it also continues with the new one that was just released by HTC a couple of days ago. In case it matters the phone is unlocked (using jump_spl and the other related tools and procedures found here, thanks).
Do I just have a defective Tilt? I mentioned this to others in my office and a few folks also claim to see this, and like I said I have seen *some* mention of this on the internet... I'd be astounded if this were really a problem endemic to all Tilts -- would people really put up with this?
Anyone have any additional insight?

It used to happen with me when I had the stock AT&T rom. I flashed the stock HTC rom and I don't recall ever having that problem, and now I've flashed SNE v2.5 and I don't have that problem.
My suggestion is to flash a new rom and see if that helps, and to make sure you're using a correct radio.

where do I get official htc radio and rom downloads?
hi folks,
where can i get official HTC radio and ROM downloads? I have an HTC TYTN II (acquired in Hong Kong) with ROM 1.56.721.3, Radio 1.27.12.11 & Protocol 22.45.88.07H just last month and already I'm encountering problems with the phone just losing the signal and staying lost and I'm considering upgrading however since my phone is brand new (practically), i want an "official" upgrade so as not to void the warranty. any help would be appreciated.
thanks and best regards...

I'll have to decide whether I have the cohones to flash an HTC ROM. Might at least be worth a try.

try this, go into comm manager, than settings for the phone (right soft key), than over to the Band tab, if I select the network type as GSM and leave the band on auto mine will contstantly serch for signal. i know this because my office is as close to a bomb shelter as they come and it never stops searching.
another good to this is battery life is improved
the BAD, if you want to use 3G you have to turn network back to auto and band to auto. not really a big deal cuz i dont have 3G here (yet).
a little workaround that works for me.

Thanks for that... I am running an AT&T ROM and even though I've supposedly turned on the Band tab in phone settings via KaiserTweak, I do not see a band tab. Should I?

I have almost this same exact problem! As of two weeks ago, my tilt started not allowing me to make calls
I then realized that it was also sending all my calls to voice mail. Thing is, the phone says that I have signal and has the Edge connection sign at the top. Whenever I try to make a call, the phone says "operation cannot be completed" or it will simply beep at me as if the call ended, right after it started.
A soft reset allows this to work. I've had this problem even happen right after hanging up with someone, and then trying to redial another number 5 seconds later. I doubt the phone really lost the signal.
Any ideas?

Hello

I had the same problem with my O2 XDA Stellar, it was fine for a couple of months, then I could hardly call out on it, email wouldn't send, could rarely go online etc etc. It seemed to be better on GSM/GPRS than 3G, HSDPA etc. I assumed it was a harware problem & as it was under warranty I got a replacement from O2 & it's been fine so far.

AT&T replaced the SIM card in my phone and I believe this has fixed the problem. I have lost signal many times (elevators, garages, etc) and it recovers each time.

Atrix HD - Having intermittent signal loss using Straight Talk.

The wife and I have Atrix HD phones that we bought used but in great condition a couple months ago. We purchased the Straight Talk at&t compatible micro sim kits from walmart.com and set up our service. We previously had Samsung Captivates also on Straight Talk and they worked flawlessly. I put in my APN settings and I get data and MMS perfectly but occasionally I get a red triangle where my signal bars should be and my phone says "Emergency Calls Only" and I will wait 30 seconds or so and my signal returns. There is no steady decline in signal that leads up to this. It goes from like 4 bars to a red triangle with a cross inside it.
I live in a fair sized town and have always had 3 or more bars of at&t service with phones in the past so I do not think its an issue with poor coverage. I am attaching pictures of my APN settings.
Any help would be appreciated.

I'm having the exact same issue since switching to to the 4G LTE micro sim. It only seems to happen on mine when I'm connected to Wifi though. I get the red triangle intermittently. This never happened to me until I went from the old sim to the new one. Can't find anything on it yet.

same thing
The same thing is happening to me here as well but using a Net10 LTE sim card (same as straight talk basically). I notice it the most after I complete a phone call. It takes a minute or two to regain service again. This is really annoying. Would like to see a solution to this problem.

So I worked with Straight Talk support for about 5 days, back and forth, bounced to several reps throughout and nothing substantial has come of it. It seems a little better after they made "adjustments" to my account as they put it, but I still get disconnected from mobile data when on wifi.
Don't get me wrong, their support people were very responsive and seemed to genuinely want to help me, but in the end they said "your ticket has been open for more than 24 hours so it has been closed. If you continue to have issues please open a new ticket." Anyone else have any luck on this?

I also was having this problem found that if you edit existing att apn (phone needs to be rooted)with sqlite editor it seems to work fine.
tether also works fine this way.I am still not able to get lte to work with straight talk even with new sim.

Just to follow up. As usual, it seems with ST support, one rep tells me they have some things they can try once I call back on another line and then I get a new rep who says nothing can be done until 10 people complain about the exact same issue I'm having. I'm assured this is an isolated incident...
I went ahead and purchased a new SIM card (looks different than the first LTE card I had) in case I had a faulty SIM. Worked flawlessly for a day and now it's back to the same issue of cutting out completely throughout the day.

same problem here on wifi get red triangle (especially after phone call).
More since i switched from 4g sim card to lte sim noticed that data disconnect from time to time like make impossible to watch video flawlessly...
with old 4g was yes only 4g but never loss a bite....could watch anything also streaming tv.....now it is impossible.....
the end of the month going to switch to old sim and see if the problem is in the new sim cards they tried may be to limit access or is in the new service doesn't matter what sim card you possess..
we'll see...

Switching to my old sim was my first thought to. However when I tried it didn't work. I called ST and they informed me that once you switch sims, the old one can never be reactivated. On top of that they don't offer the non LTE sims anymore. Such a pain. Hope you have better luck though.

Some one could correct me if I'm wrong here but I'm pretty sure this is a result of ROMS using a 4.4 rom. Modem crashes. If you want to test it run a Stock ROM... If you are already using a completely stock ROM then Idk what to tell you. But same thing happens to me using any version besides stock. And yes only when on WiFi

Then unlock your bootloader and try flashing different radios from the different stock fastboots we have. Depending on the fastboot I can have next to none or almost full in my bedroom. For me, ATT JB is in the middle, JB Mex Retail is the best, Bell ICS is the worst. ATT ICS was about the same as ATT JB.

For the time being, I just switched to Aio and so far so good with LTE coverage and no disconnecting issues. If they return I'll try different radios as you suggested.

So I've been with Aio for about a week now and everything is working great (knock on wood). I've had 2 mobile data drops at work with Wifi turned on, but they only lasted for a second and I do have really bad reception here inside the building. Outside of that no issues at all so far. I'll update if anything changes.

SMS / Text Messages Sporadically Don't Come In

I have an unlocked british d5803 that I am using on ATT in the states. Every once in awhile it just stops receiving SMS. The SMS will eventually come in all at once at some point in the future, or if I restart my phone they will all come in. I haven't been able to replicate the issue. It seems to just happen at random. Today was the third time I have noticed it happen.
Has anyone else noticed this issue? At least I'm not losing any texts, they come through eventually, but it is still a real pain.

Ive been having the same issue. For me, my messages wont send out randomly?

I'm having the same problem as well. I believe that when 4G LTE service gets dropped, the phone doesn't allow texts/calls to come in through the lower bands. The texts eventually come in a few hours later all together. I'm going to try to do a sony software repair or return the phone.
I wish I could love this phone, but i just can't with this issue.

I would suggest downloading the advanced signal status app and comparing it with other phones.

That doesn't sound good. Where did you learn about this? I always tend to blame the network for any missing text problems rather than the phone. Last week, for example none of my texts were getting sent. So I tried my GF's iPhone on the same network and same thing was happening, so I assumed T-Mo was having a hiccup. It worked 5 minutes later.

I would use the FlashTool and install the US version software and give that a try. There might be some changes in the radio part of the US software to better connect to the towers.

I am just speculating. My work phone is also on AT&T so I have been using it to troubleshoot. I don't believe the issue to be a network problem.
I'm going to try flashing the US firmware as mentioned below. As soon as I comfortably figure out how. .

I've only had an issue with receiving SMS, never sending them. I think. I'll pay more attention, it hasn't happened again since I posted this. Maybe I just need to do a fresh power cycle on the phone every couple of days. Sucks, but wouldn't be the end of the world. It's a shame, this phone is perfect in every other way.

Thanks again for your help

I am researching the Z3 C for use on TMobile/Metro and
GREATLY appreciate this honest description of this Problem.
AT&T nor Tmobile dko NOT seem to have this problem with Networks-it would be widely reported if they did.
I never had it on MetroPCS or MetroPCS Tmobile after Merger on Carrier LG Motion 4 G.
My theory is the Data Transfer is not automatically
reassigned or transferred to the lower speed 3G Bands for some reason, I am not a tech or,Dev so guessing that
Sony does not have Software Optimization tweaks that
we take for granted since they are not on many Carriers .
Guessing that the TMobile Z3 and Verizon Z3v will or have been optimized or will be for no data pause, text pause etc.
I can NOT have this because meetings are sometimes adjusted via text, phone used for Business.
Alpha probably even unlocked will have fewer issues , but never used an unlocked phone-
For RELIABLE texts, data, do you NEED a Carrier Branded, Optimized Phone.?

[SOLVED] Phone network issue

Hello everyone,
Informations
Phone : Nexus 6
ROM : Euphoria OS 1.0 with included kernel
I have a little problem with the phone network...
I have just install the ROM (3days ago) and everything worked fine.
After the first reboot, I had a network problem: no more network (just phone)
Bluetooth is OK,Wifi also ect...
No extra apps installed.
Any idea?
Thanks
Edit : French phone/network (FreeMobile)

I am having issues over here also. My data randomly stopped working on my way down to memphis, randomly would start to work again. I tried a new rom, it slightly got better, but would cut out of data every 5 min. Kinda got it better by switching to tmo in the apn's. Now just installed sinless, and it is no longer working again.

So, same problem and no fix...? :/

Holy cow! I thought I was the only one! I mean this problem really sucks(and I have wasted a lot of my hours trying to fix it), and have been thinking of creating a thread on this problem until I saw yours.
Okay let me start with what I'm on:
N6: 64gb blue
Rom: Stock
Rooted: Yes
Any other modification: No, only think I did was unlock and do chainfire su root.
Network: VZW
I have had this phone since Dec with no issues other than random reboot every so often.
Now to the problem I had, I went out to the middle of MO for a weekend get away (on Feb 14th). The whole time I was out there it showed 1x even though I was still getting LTE speed. Didn't think much of it until we moved further into the hilly parts of MO were I lost service. Thought it was just where we were at, and thought it would come back once we got back to the hotel we were staying at. It never did. It would say "No Network found" only allow 911 calls.
Spent the next 4 days working With VZW with several trips to the store, and talking to tech support. They made sure my IMEI was not blocked on their side. We used several sim chips, they would all do the same thing, quickly connect then disconnect and go back to no service.
So I did a factory reset, still didn't help. I finally did a fastboot flash of 5.0.1 stock again, this fixed the issue. Until I used titanium backup to restore my sys setting. Then it would drop and not reconnect after the reboot. So I did fastboot flash again and it hasn't happened again since last Thurs. I just restored my app's again to make sure it wouldn't fail to connect over the weekend, and rebooted several times. No issues so far, but I called Motorola and they are RMAing me a new one, because I don't have any trust in this one anymore. They are out of 64gb ones, and they will get back to me in a week.
Questioned to anyone who has gotten a RMA from Motorola:
Are their "like new" replacements okay? I got a few from them when I had my droid x, and they were crap. So I wasn't sure if that is still the same for the N6 or not. I have a feeling its not, but just wanted to get other peoples input on that process.
Thank you for creating this thread, and for everyone's time!
Edit: Had the same issue network wouldn't work, however WIFI, Location, Bluetooth would.

Check your APNs..... make sure you are on the correct one, and that both of APN protocols say IPv4.
Sent from my Nexus 6

APN is for Internet(3G) and MMS, no?
Because we have a phone network (call & SMS) issues.
On my side, APN are OK, but still don't work...
Edit: New !
Everything works fine on :
- Paranoid Android 5 Alpha 1
- Chroma (Latest)
But not work on :
- Euphoria
- Stock ROM
Edit 2 : It works now !!
I seen that I had several issues around the APN side. I mean, I can't add APN, sometime I can. Sometimes APN reseted themselves, sometimes it was OK. Then, I had read the solution above: security tab.
I had just remove my 3rd party lockscreen (HiLocker). Restart the phone and voilà ! After the reboot, my phone ask me the pin code, and all APN are here.
I hope it can help...!

Some times I will see the APN settings, and sometimes I won't. Right now I don't. When it does show up it shows VZWINTERNET selected. There are ton of other options, but they don't work either when the problem was seen.

Is what your experiencing data going in and out? I'm on Sprint and I thought maybe it was just an issue with Sprint. I have or need to read up more on APN because it does get bothersome. I even have issues where sometimes my SMS gets hung up for minutes in sending mode before they actually send. Would be nice to have this corrected.

No my whole problem was that it would drop and no matter what I would do wouldn't reconnect to the network. I tried a lot of things to fix it (see above). APN would appear and then disappear from the menu. Right now its working on the network as of last Thurs. and APN options is not there.

The APN option will not show for a CDMA Carrier, Sprint or VZW, in your case VZW. APNs are set by the Sim from Verizon so you shouldn't be messing with those, nor should the option show up under mobile network settings.

It was like you. Sometimes network was OK, and sometimes, it was down...

So current working theory is that it was a software issue that cause the problem. I'm just unclear as to why it happened, and how to stop it from occurring again . I do have OpenDNS enabled on the phone, could that cause the problem?

Heres my problem, I'll drop out of an LTE zone, and 3G/HSPA will come on line. Only if its on 3G I never get any data, and sometimes with HSPA too. Not until LTE comes back on line again, but then if I'm trying to stream say music 3G/HSPA wont let LTE take over again for a pretty long while.

[Q] Losing signal completely

Hello. Have any of you experienced total signal loss? (The triangle in the status bar is hollow/empty). This happens seemingly on random and it "fixes" itself in a minute or so, and I can make calls and have mobile data.
Thanks

I have been also facing this issue lately with different roms. In my case, I loose the network and have to reboot multiple times to get the network up. Sometimes because of this, my phone shuts off. Not sure what is happening.

I flashed Dirty Unicorns a few days ago, and signal would drop every few seconds. Turns out the APN was set for MetroPCS, changed it to T-Mobile IPv6 and it fixed it.

I found my issue is related to my network operator. I am not sure why this happening, everytime I reboot or shut it down, I loose the signal and it takes many attempt's to get a connection. It could either be lollipop bug, network compatibility or issue with the device. Will find it out on Monday.

same here
I've been dealing with this same thing for two days. I have Sprint.
I was on Chroma and traveling. I noticed I lost data during my drive. Once I got to the location, my wife had full 3g and I had nothing. I thought it must have been from dirty flashing an update. I wiped and flashed again chroma with the sprint.zip for apn. Still didn't work. I occasionally would connect to 3g but would lose it randomly for long periods of time. I ended up walking around with my verizon hotspot to have data.
I just flashed stock and I've been waiting 10 minutes for it to try to activate. I'm hoping it will work this time. What a mess this phone has become.

It seems like it's a lollipop bug. I tested my sim on a different phone and multiple times, I rebooted without any issues. I wonder if Google messed with lollipop or is it Motorola.

Yeah, even if there the signal bar gets empty, it doesn't interrupt in incoming or outgoing calls Even mobile data works perfectly fine. For me it comes to normal after 5-6 seconds

For me it does interrupt calls and I don't have mobile data. I really hope its a lollipop issue. I guess they can add that as number 1500 to the bug list...

I am currently experiencing that exact same problem no matter which rom I am using. It is really becoming a PITA. Spent 950$ for this POS phone.

Not a lollipop issue.

Few things to explain if you really want to find out what is wrong. Who is your carrier? Or you running stock or modified ROM? Are you rooted? Giving information like this may help you get to the problem. If it were a lollipop issue, don't you think everyone or at least a lot more people would be experiencing the same thing and posting about it???? Come on guys, be a little more precise when posting issues with said device.

Hi,
WIth Fido in Canada. As some others have posted, if I choose LTE (recommended) in Preferred Network Type, I lost my connection every 15 minutes for 1 minute. If I set to 3g, all is fine. I tried the sim in my nexus 5, doesn't happen.
Tried CM and some other AOSP customs roms, always have the problem. Also tried different radios., same problem. I will definitely retry with the factory image soon, but I have strong doubts it's the OS. I contacted Google, they are sending me a replacement phone.
It's insulting to shell out 950$CAD for a new phone, have it bug on you, then have them ship you a freaking refurbished device. I have a 64GB midnight blue from the first Canadian run (I was one of the lucky bastards, or unlucky!). Then they wonder why people buy iPhones...yes they are very limited, but at least the damn thing works.
Almost every single Nexus I have purchased has given me problems (4-5-6-7-7(2013)). The only one that has yet to show me problem is the 9, but that was a gift for my mother, so she won't even notice if things go bad. I am definitely done buying a Nexus device when it is released...lol

Forcing 3G
Hey Guys,
I tried switching from Euphoria OS to Omnirom but no dice.
I deleted all unused APNs and forced 3G connection, rebooted and it seems to be stable for now.
Hope there's a better fix soon.

Got another nexus 6 from Google...same problem. Every 10 minutes LTE drops. POS....

No problems here.. Sounds like a network issue not a hardware problem.
