"No service"

Several times recently (I'm not sure whether it started after I installed the OTA update or if it happened once before then) I have noticed that my phone says "No service" and doesn't pick up T-Mobile again until I power cycle.
It's not that unusual for me to see 0 bars of signal strength in my house; there are dropouts at various places, and I saw the same thing with AT&T on previous phones, so it's not a T-Mobile or Nexus One issue. The problem is that, once every few days, I will pull out my phone and see 0 bars and "No service" instead of "T-Mobile," and nothing short of a power cycle reestablishes the connection. I've tried going into and out of Airplane mode, with no effect, and I also tried using Settings -> Wireless & networks -> Mobile networks -> Network operators, and it never found any.
Maybe related is that when I try to power cycle after this occurs I have trouble doing so -- a few seconds into the shutdown sequence the circling arrow stops moving, I get some sort of notification "ping" and the trackball lights up, and the phone just sits there for a long time. Eventually it reboots -- whether because whatever it's waiting for times out and it continues the shutdown sequence or whether it's responding to my frustrated poking at various buttons while it's sitting there apparently doing nothing, I don't know.
If it's a hardware issue, it's very intermittent; I always have service after the reboot, and as I said, this only happens once every few days. I'm inclined to think it's a software or configuration problem (I'm using the stock 2.1-update1 firmware). Any thoughts or suggestions? TIA.

It happened again this evening when I had some more time to play around with it, so I have a bit more information about this problem.
When I tried Settings -> Wireless & networks -> Mobile networks -> Network operators, the circular arrow spun for a minute or two and eventually a little pop-up appeared saying, "Error searching for networks" or something like that.
It occurred to me that the SIM card might be bad or have a bad connection, so I installed an app (using wifi -- which, BTW, I had on throughout this whole process) that allows you to copy your contacts onto the SIM card and ran it. That seems not to be the problem, though, since that app could access the SIM card just fine, while I still had no service.
I toggled Airplane mode on and off, but there was still no change. I then again searched for network operators; the circular arrow appeared and stopped, then a couple of seconds later the phone spontaneously rebooted and I have service again.
Anybody have any guesses as to what these symptoms might indicate?

Every so often i got service but I cna't send text messges unless I power cycle. If I try to airplane mode cycle it won't let me get out of the mode.

wow, a bit refreshing knowing that I'm not the only one with this issue.
I'm on T-mobile and within the last week I've had 2 occassions where I looked at my phone and noticed no service, a power cycle caused it to freeze on "powering off" screen and I would have to pull the battery. After it booted it I had full bars again.
Within the last 2 weeks I have had issues where I would not be able to send a text messages until i power cycled.
The last time I had no service was 4 hours ago. I had to pull the battery to power cycle and get service again.

Thanks for the reply. I, also, pulled the battery the first time it hung in the shutdown sequence, but as I said in my first message, since then I have managed to complete the power-down after the hang, either because whatever it was waiting for eventually timed out or because something I did (e.g., holding down the power button for several seconds) overrode the wait. Next time it happens I'll try just waiting to see if it will complete the shutdown on its own.
Just out of curiosity, did you have wifi enabled at the time this happened? Bluetooth? I'm not sure whether it's relevant, but I leave both on all the time.
As for the text message problem, I don't send a lot of texts, so I probably wouldn't have noticed if I were having that problem and can't comment on any correlation.

Oh, and a couple more questions: do you have NetCounter installed? And are you in a location where you sometimes or frequently get 0 bars of signal strength?

I have had similar issues with other phones...
For me it turned out to be an issue with my sim card.

I usually have both bluetooth and Wifi enabled all the time...
Dont have netcounter installed.
Dunno about the SIM card issue, unless its a combo of the N1 and my SIM card, because I swap to using my BB 8900 once in a while and I never have text message or no service issues.

Im experiencing the same problem, I have dropped calls in some spots around town (when changing towers it seems), I drop service when inside my home and cant send texts (until a power cycle), horrible 3G speeds of less than 1MB/S all around town (driving and standing directly under the Tmobile Tower that across the street from the tmobile store).
NONE of this happened with my G1....my 3G speeds always sucked though but were usually around 1.5-2.1MB/S.
Im located in Fredericksburg,VA.
(MY PHONE IS NOT ROOTED AND IS RUNNING THE OTA UPDATE1)

Im pretty sure it was the radio update, cause after i get out of a place where i get no signal at all, and i get to a open place I have to reboot the phone to get signal again

I've been busy for the last six weeks or so and haven't been following N1 news around the net. Has anyone heard of any progress on this issue? It seemed to go away on my phone for a couple of weeks, but it's back with a vengeance: it's happened to me about once a day for the last few days, which is more frequently than any time since I've had the phone, so I'd really like to get this fixed somehow.

Can you take a youtube video of it? the more the better to get Google to fix it.
Also these issues seem to be related over here too http://www.google.com/support/forum/p/android/thread?fid=1cc152dbb797df2f000483d7c88e343e&hl=en

Thanks for the link. It seems to me that several different problems are collected together there; mine is specifically the one where I go to zero bars (which happens fairly often; I have several dead spots in my house) and it never comes back.
A video of this would be pretty boring to watch; there's really nothing to see. The signal strength shows zero bars with an "x" and the home screen shows "no service." Trying to power off, or going into and out of airplane mode, shows the spinning arrow for a few seconds, then it stops; a few seconds later the screen goes blank; then a half-minute after that the multicolored "X" appears and the phone reboots itself.

No SMS Gateway
I think this is a separate issue for the phone not switching back to a connected state with the service provider. In the case of SMS, I have also noticed that you may have signal but you have no SMS gateway. No idea where it goes or why it does that.
For whatever reason you loose the SMS gateway phone number settings and become unable to send text messages without a reboot. This is evident by visiting:
Phone
dial *#*#4636#*#* (if you happen to mis-dial this start over after clearing the display or it won't work)
Phone information
Under SMSC: press Refresh.
If no number displays (in my case +12063130004) then you have no route for the SMS messages to take. Entering that number and pressing update will fix it but just restart so it can pick it back up from the SIM/Carrier configutation.

I have this issue sometime in a supermarket here, if I'm in it shopping for a while I loose all signal and have to reboot, also happened with my MyTouch jut didn't have to reboot the phone, but if I'm in there for a quick purchase, it works OK

@wmm, I'm seeing exactly the same issue (zero bars + reboots) and found another guy on the cyanogenmod forum with that problem. Maybe you can add your last_kmsg to this thread, even though you're on stock. http://forum.cyanogenmod.com/index.php?/topic/1599-loss-of-signal-no-reacquisition-issue/

Yep, that certainly sounds identical to my experience. Next time I have the problem I'll force a crash by toggling airplane mode instead of trying to power off (it seemed from the thread that last_kmsg would not be saved if there is a normal reboot, and indeed I have no last_kmsg from the reboot that resulted from trying to power cycle after the last time I had the problem).
Thanks for the cross-reference.

That would be nice, but I haven't seen any activity on the issue on the Android developers' board. Speaking as a programmer, these intermittent, once-every-few-days kinds of problems are a real pain to debug, so I can't blame people for not wanting to tackle the issue...

I had this issue but fixed it by installing the Radio Rom and OS again from the last update. Has not done it again. Now its a power button issue lol.

Evo battery life trick read

For those of you having battery issues I found a way to DRAMATICALLY improve the battery life.
I tried this and I have seen a huge improvement.
First things first, go into Settings> About Phone> Battery> Battery Use> Cell Standby. Assuming your phone has been on, or off the charger for ~10 minutes, it should show Time Without Signal at around 50%.
Next thing, press HOME, and bring up the dialer. Dial *#*#4636#*#* (Do not press "Call"). After a second, it should bring up the "Testing" menu.
Go into Phone Information, press MENU, and tap "select radio band." You should experience a Force Close, don't panic, this was supposed to happen. Scrolling down shows that the preferred network type is GSM auto (prl).
What this means is that even though you are connected to a CDMA network, your phone is trying to find a GSM network, preventing the radio from sleeping, and causing excessive battery drain.
Remedy this by tapping GSM auto (prl), and changing it to CDMA auto (prl).
Now your done, your TWS should drop dramatically, and you should experience much better battery life!
Note: You need to do this every time you reboot.
I wish there was a way to make an application to toggle this thing on and off so you don't have to do it every time you reboot the phone.

Going to try this for tomorrow and see how my battery life is. Seems silly that with all the customization HTC did to the OS they missed this detail.

seems weird; has anyone confirmed if this works?
-m

Just checked mine and it was already CDMA(auto).

btw for what it's worth, my EVO has been off the charger for ~2 hours, and the cell standby details just shows "time on: 2h 19m". Mine is also defaulting to 'CDMA auto (PRL)'
Perhaps a recentl prl update fixed this?
-m

Nice find though - the battery history tab (especially the all time tab) is awesome..
For instance, I've been seeing my GPS turn on and stay on while indoors.. according to these stats, the 'movies' app is the one that was using it the most..
-m

I found mine in CDMA already too

Mine was GSM my son's was on cdma, we both did the prl updates and both of us did the sd card update as well.
I guess some phones were on cdma by default some weren't.
Maybe thats why some people are calling other crazy for the battery drain.

thanks...interesting find...mine was on gsm. everytime i reboot?! damn.

Mine was set to CDMA with Cell standby of 48%.

mines was on gsm also..but i rebooted and it stood on cdma..it didnt default back

There is an app in the market called "network" that is basically a shortcut to this menu.

You could just use spare parts from the market place it shows you all of that

Mine was on GSM. I'll see if my battery life is any better tomorrow.

Mine was set to GSM. The phone came from Google I/O so maybe that was a bit different? I'm excited to see how this improves it! If it does...good find! If not...still probably a good thing to change!

Thank you so much for this, it seemed to fix my sporadic signal issue!!!!

just changed mine to CDMA thanks

Thanks for the tip...Mine was set to GSM.

Mine was already set to CDMA auto (prl). I saw another option was for CDMA only. I wonder if there would be any difference with that selected?

Problem when I remove the battery.

Hi,when I remove the battery from my device so my date&time get changed.Restore to the latest definition .
If I'll define the date&time in the device for example 18.05.2011 23:00 and five minutes later I'll remove the battery no matter if I before it turn off the device or not.
Still when I insert the battery and turn on the device ,my time&date will be 18.05.2011 23:00.
The five minutes dont count.
I've this problem when my OS is wm6.5 or android.no difference.
Why?
Thanks.

If you just have the issue of date and time mismatch, try to set the option to 'Get values from network'. What I mean is to set your time and date to sync with the network time, that way it will stay updated.
Regarding the issue you are facing, I can't get much information on it.

I dont have a 3g account and I dont have a Wi-Fi nearby.
So I cant get values from network...
Any solution?
Thanks.

There is probably no solution for you. Without an active power source, it won't update the time. As I doubt there is a capacitor or battery on the system board to keep the time updated, then when you pull the battery, it just remembers the last time and doesn't update it till you put the battery back in. You're stuck just setting the clock manually in that case then.

Don't pull out the battery.
I agree with Drashna, you need a time source for your phone so with no network connection you can't get one.

Are this failure valid for all HD2 devices or only in mine?
Thanks.

Hi! ive been having same thing lately. not before. have you had it always?
I think this is same thing that happened to my HTC wizard.. its internal battery for clock died after year or so and this EXACTLY same that happened with it. they replaced it at htc when they repaired its screen and it worked afterwards.
or capacitor whatever its real name is.
any more people?
I have had hd2 since january 2010

I had my device for almost a year...
And if I remember right I don't have this failure from the beginning.

it does it on mine for android but normally corrects itself by updating itself fromthe network

(RE-Edited)Please Help Me (Cuban XT-907)

I took this screenshots last night, the kernel wakelocks(smdcntl0 and radio interface) are causing the massive drain in idle state, i searched the forums and havent found anything regarding these two wakelocks, this is in Cuba were there is no internet usage whatsoever, no wi-fi, no gps, nothing, this happened after i left the phone one week in airplane mode and then, after a factory reset, inserted the sim back in, i`ve done various flash throught RSD with the latest firmware avalble and dozens of factory resets, ever since, i am fully stock, non rooted, and with the 98.18 build, any help will be appreciated, i am going crazy with this...
sorry my english

Ive been using the razr m for a month now, last week i used in airplane mode( i was testing other phone) and yesterday when i began to use it normally the battery burned very fast, in one day it was down from 100% to 14% it usually lasted from 3 to 4 days(in cuba we dont have internet in our cellphones, just 2g for calls and sms, no wifi, just database based apps and games and media playback). i am using the stock rom(4.1.2, sist. version 98.16.1), no root, bloatware disable, no gps,the only uncommon thing i did was a factory reset through the phone settings...

Airplane mode should have saved your battery tremendously (since it disable all radios) and 2g speeds should be a battery saver too, even in poor-fair signal coverage, and factory resetting should have cleared out any battery draining apps that you may have experienced before doing the reset. Have you been more active with the phone lately? From what you are stating you shouldn't really be suffering from heavy drain.

in the past month i used the same way and it lasted like 3 or 4 days(only 2g), i am not doing anything unusual with the phone(with no internet what can you do), only 2g and the occasional gaming, i resell phones here(in Cuba) so i know a thing or two about android and i can tell something weird is happening after the factory reset...thanks for the quick reply anyways...i never post anything here because of my slow LAN connection, right now i am updating through connectify(wi-fi) to the last OTA and see if that solves my problems...thanks man and sorry for my english...

nooooooooooooooooooooooooooooooooo. don't update - that will lock the bootloader, thus preventing you from slapping on the latest/greatest custom ROMs...

well its updated now...i took out the micro-SD( a 16gb Polaroid class 10) and did another factory reset after the update and the problem continues...last night the battery burned in idle state from 100% down to 9%, i took a screenshot but don't know how to posted, i will do another factory reset (this time from the stock recovery) and see if that solves my problem, another thing i noticed is that after the update in the storage settings you can see like 7 different "usb modes" or something...i most say that i am impress by how fast you guys step up and help me and i wan to say that this is a great community...thanks

i think that somehow i screw the battery at a hardware level by doing the first factory reset, this is not a normal behavior...

Please anyone????

i flashed the phone with RSDlite(build 9.8.1Q-78-1) , did a cache wipe and a factory reset and the problem continues, can someone please tell me if flashing another firmware(the 9.8.1Q-66-1) can help me, i am getting 19 hours of battery( with the phone in idle state all the time)

19 hrs is good for battery life

could be that the phone signal is not strong enough and thus causing the phone to continue to search for a strong cell signal. might want to check the network settings.

That's kind of what what I was thinking. Maybe it's searching for a data connection. He needs to disable data. Go to settings->more... ->Mobile Networks and make sure data enabled is unchecked.

does this POS work on ANY network?

i am so ****ing pissed off right now
i had a 6p working on metro PCS
a few months ago visual VM stopped working and incoming calls stopped working
i bought another 6p and had the exact same problems
the second phone bootlooped 6 weeks after i bought it
i brought the original 6p to t-mobile new sim new service and i STILL get no visual VM and no incoming call WTF !!!!!!!!!
2 different phones 2 different services 2 different sims same ****ing problems
i know metro uses t-mobiles old networks,i guess their new networks is ****ing piece of **** too

Might want to specify in the title the fact you're using some off brand cell company.
This device works flawlessly on Verizon, I had T-Mobile for about 6 months and it was fine, and now I'm on att and its as good as version was.

i am not on an off brand company i am on T-mobile now
from what i understand metro PCS which i had before uses the same network though
i was on metro for a long time with no problems
i did finally get visual VM working today but only through the app , it doesn't work in the stock phone dialer app still
i won't know until tomorrow if the issue with calls not going through when the phone goes into doze has been resolved or not
i changed one of the APN settings from v4 to v6 i think that is what made it work , the guy at T-mobile changed some other settings too though i think it took awhile then the visual VM app finally asked me to set up a new pin but it still wouldn't work i had to call and have them set it up on their end for it work
i feel like the phone not getting incoming calls is an android problem because it seems to only happen when the phone is left untouched for a long time , most of the time it only will happen when i go to sleep and wake up
sometimes waking and unlocking the device will make calls come through again sometimes i need to reboot it
i think it has something to do with doze but i am not sure , it could be the network or APN settings
happened with 2 phones on both carriers

Are you on 8.1 or 9.0? Because I've seen quite a few people having issues with calls etc on 9.0, though I haven't noticed any.
It seems like a large portion of them are outside of the us though. Also are you on stock? Or a custom rom? I have noticed on some custom ROMs that my device when left overnight will stop updating. View it as the phone is sleeping so hard it just stops working, I'll wake up to no alarm and notice even my clock wasn't updating.

It seems to be working now ,after much messing with APN settings and showing system apps and disabling optimization for any apps and system apps that sound like they are related to carrier or phone.
No visual VM from dialer app tho
The issues just started one day a few months ago out of the blue i think T-mobile/Metro PCS made some changes to their network and that is what caused the problem.
I also noticed that when i had the sim out of my phone that the battery lasted forever
and when i put it back and was having the issue the battery drained really fast , i have always got extremely poor battery performance since i got it
but now it seem like the battery life is a lot better since the phone has been ringing and Visual VM working
So can having incorrect APN settings dramatically effect battery performance, cause it seem like the battery is working better now even though i have turn off like 7 or 8 apps/system apps battery optomizations

Well sure, a large chunk of your battery is eaten up by the radio, just like if you toss on airplane mode and just use WiFi you save battery. If your radio is constantly trying to search for signal it can have a huge impact on battery life.
You mentioned APN settings, but sure if that means you've messed with that, but if not I would. Google all the different apns they use and try entering them manually

Not sure honestly. I usually just toss it on airplane mode if I'm in an area with **** tier service.

No Prob Here
Hey, I am using Metro PCS and I am having no problems. I have tried a few different AOSP roms and none have been an issues. I am on AEX 9.0 right now. I do know that I had to reinstall the default android/google dialer app as this one wanted to use something different.
If there are any network settings I can help you out with let me know.
