[Q] Have to Reboot to get the Network Back<<<<

ok, so i have this thing for a lil over a month now i think maybe more....
but i have noticed that no matter what Rom or Kernel, even Stock.
if im in an area where i lose signal.....it may NEVER come back unless i reboot my phone. not a big deal in most cases but unless i look to check i may have no network for a couple hours before i notice that i have to reboot my phone. which means i get no calls and no text.
is there a fix for this or is this just something that i am experiencing??

that is strange that it does not auto-reconnect. my suggestion would be to try a different modem than the one that you have been using, if you have not already tried all 3. find them here:
http://forum.xda-developers.com/showthread.php?t=1173704
both odin and cwm flashable versions. maybe you'll have better luck with signal with a different modem, so that your signal doesn't drop completely at all.

on my SD card i have had all three modems for a while now that i had been flashing to see which one i would stick with. but my phone has been doing this since day one. on any rom or kernel or modem. i just wanted to know has anyone else seen this or is this just specific to my phone........
at that point i would be looking to get another one.

you may not have to reboot - have you tried just toggling airplane mode on and then back off? that restores data when it goes out for a lot of people.
if you've tried that, and it doesn't work... not sure what to tell you, except to exchange the phone.
i rarely ever have a strong signal - usually worse than -100 dbm, especially at my house - but i've never had the problem you are describing.
hope you get it worked out. maybe contact at&t or samsung for support also, while you are on the stock ROM.

So far the airplane thing seems to work. so i will ride with that, it doesnt seem to happen but once a day or so......so if i can just do that then i will just deal.
thanks for the idea bruh.

No Network problem on samsung Infuse

Grey signal with x wont reconnect

I have this issue when im at work where i get crap att coverage where eventually from being low for so long and staying on wifi my phone signal goes to zero and a grey x shoes up above them.
This wouldnt be so bad but it wont reconnect with a reboot or airplane mode reset which means if i dont check my phone i get no calls or info.
Is this normal? Is there a fix?
Thanks

This is an old issue. I'm not sure when the fix happened or what ATT radio would fix it for you but there is a simple (ish) solution. Basically, whats happening is that when your phone loses signal for an extended period of time it shuts off the radio and then cannot restart it. Using NoBars will stop your phone's radio from dying like that and will just periodically poll for signal.
That will fix the issue but just to satisfy my own curiosity, on your SDcard are there a bunch of files called Radio Dump and then a bunch of numbers?

Sorry posted on my phone and didnt notice the grammar errors
Yes i have the radio dump files but havent checked since installing the F1 radio.
I will try that app since this issue has followed me on multiple roms and radios
If there was a fix i havent gotten it
Thanks man
Edit
Just installed nobars but realized its a battery saver like juice defender
I will keep my hopes up tho
This ONLY happns when at my desk at work where att has no dark hold on me
Sent from my Nexus S using XDA App

you could try manually resetting your radio if that is actually the problem. just dial *#*#4636#*#* next time you're at your desk and go to phone information. if you scroll down it should say either turn off radio or turn on radio. try turning it on if it's already off, or resetting it by turning it off and then on again. I don't think this would be a permanent fix though. just a temporary solution when the problem arises.

Nobars will shut off your radio and stop it from dying. Trust me it works. My wife and I used it foe months waiting for the issue to be resolved. The radio dumps mean you're having the same issue.

I actually go into the carrier menu when i install a new radio anyway. Going in and out of airplane mode resets the radio but the problem is if I dont actually look at my phone (in my pocket) i wont know the radio shut off and can go through the day without getting any contact. I know its not the rom cause Im on stock. I know its not the radio cause I have tried about every one.
Its got to be a mix of crappy ATT service (which makes me wonder if resigning was worth this phone for free) and the nexus s hardware.
I am seeing if noBars will help. You would think this would be something google would fix ASAP tho as its happened since day one almost.

It is odd since this was a massive issue from day one of the Nexus S but that was before any of the other variants and it was fixed before any of the other variants launched. Since that fix, I've not heard of anyone having the issue any more with any variant. Part of the issue for my wife and I was that we lived in an area where there was really no good cell coverage from any company, so we stayed with T-Mo in spite of that knowing that we were moving soon to an area with great T-mo coverage, but being out of service so much resulted in similar issues as you've had: we would be constantly restarting our phones to see if there was anything we were missing. I do believe this will work for you, and I hope you find a permanent solution soon.

Thanks for the tip but i guess i am the lucky guy who still has the issue lol
Maybe hardware related? I will see what ice cs brings me
For today nobars helped but i did notice some batt drain from it but very minimal so its a keeper for now

Data speed icon?? Gone?? Invalid Sim sometimes??

Okay I have been having the t-mobile "invalid sim card" issue and the phone currently is running with the t-mobile carrier logo. I was able to make calls, and connect via WiFi. I am not able to access the web2go page when I select data in the "wireless & network settings" page with a check. I used to be able to at least access this page with wifi turned off and it would show a little 4g icon on the top? I will post some screenshots. I downloaded GeRIL just to see what it said? I think my phone is rooted? I ran superuser and said the phone was not but the last action I did before getting the t-mobile to show up was a zip restore with CWM so I assume it's rooted? Might be just a flash? One other thing is that I have the WiFi and GPS on and it does not appear to get my location for weather in the weather app?? I can open Google maps and GPS is within 60 meters of my location. I want to reboot the phone but am afraid it won't be back to normal and I will get the error "Invalid Sim Card" again? Is there anything or tests to run while the phone is on the t-mobile network I should check first before rebooting? Or files I should try to use or flash? Or any service menu codes to run diagnostics? Thanks in advance. I forgot to mention that I will be getting a replacement from t-mobile in a week, I did the online chat and they said they will send a replacement under warranty. The box has a date of 7/29/2011 so the phone is about 3-4 months old? The phone is unlocked and has been rooted before, but the issue happened days before I modded this G2x. Basically, today it could connect and tomorrow it might not...or If I reboot It usually goes to the "Invalid Sim Card" I have read other posts with issues of the same type from other users but found no solutions?? Baseband, RIL, Sim ect...all points to a bad phone(using t-mobile) because If I use any other carrier card in the phone it works without errors. That makes me think it's a firmware with t-mobile issue but I could be wrong? Hopefully if the replacement goes thru the same ICS 4.0 will be out and make this phone a beast again?

This might work or it might not: rename your APN manually (Settings/Wireless/Mobile networks/Access Point Names/edit) you can either edit or restore to default to restore mobile data connectivity. Try restoring to default.

I just accidentally hit Airplane mode and it killed it!!! Now it's back to the Invalid Sim Card error again...bummer!!!!

Wait a minute...I waited and read a few posts and clicked the Airplane mode off and on again and it came back to the t-mobile carrier..??? I still have not rebooted the phone though? Hmmm...should I?

Did you get a new sim card when you got the phone? I remember when I got this phone they told me not to use my 5 year old sim card from my previous phone. I say try a new sim card, if that doesn't work try to reset the apn with the instructions I posted last, and if that doesn't work it might just be a bad sim card reader.

I think more on the lines of a bad sim card reader...I have a new sim card...about a 3 days old, got it from t-mobile cause i had the older sim with the larger gold contact patch. The phone is already on order...they said 7 business days..

Yes some times that will work. Other times might take 2 reboots. Also sometimes toggleing airplane mode can bring back apn. After a few sim cards and all my problem went away. When I had the issue I was cm7 rom. Stock Rome didn't really seam to have this issue.

just to close this thread I already received my replacement phone from tmobile. I am no longer trying to track down the issue. Thanks for all of the replied and comments. every one who contributed will get a thanks from me.

Yes doing a hard reboot will reset the Apn/data loss problem. (Also toggling airplane mode would some times reset it.) This is only a tempory solution as it could happen again. On cm7 rc1 it would happen to me at least once a day. As well as many others. Off of the top of my head it was something wrong in a radio file.(? Not sure what file) shortly after the release cm7 stable 7.1.0.1 was posted. I believe that had the patch for the data loss issue. It is possible that some cm7 based Rome may still have a data issue loss as they might not have the updated patch. At the time stock based Roms did not have the issue and as far as know. Some people faced with this issue could have had a faulty sim or phone. The other thing that was happening during the life of this issue was how many people running cm7 based roms didn't have the issue. I no longer have this issue. I followed the bug report that was submitted and sealed out the sim card twice. (I think it was cm7 issue on my device) OP- I hope that this swap works for you. If it don't, I will be more that happy to help. also thank you for your service.
I have posted what I know and can remember here in hopes that it can help some one else out in the future.

When I had the phone I installed CM7, and the daily's...ect..It WAS a phone issue (hardware) I now have had the replacement phone for 1 week and no issues what so ever. That's not to say that the issue will arise again? I have rooted and am running no ROMs at the time but am thinking of going back to the FROYO 2.2 just to get the camera like it was in the older version. I hate the camera in GB 2.3.3. No zoom....c'mon LG..where did you guys lay down to sleep during this process if the development? One other feature that has nothing to do with the camera that I would like to see happen is to be able to enable a bluetooth mouse. I tried my Targus mouse and no luck. I think you can use a bluetooth keyboard but have none to test. I was thinking of shelling out the 160 smackers for the infared keyboard..small and can fit in your shirt pocket, and it's bluetooth.

phone keeps shutting off

In the past month I bought a used mytouch 4g slide off ebay in good working order. Lately though the phone keeps shutting off on me whenever I try to do anything. The phone is rooted with S-ON OFF.
I have installed many different roms but of late they all seem to be shutting off. I had this problem but it only happened every few days beforehand. After install of the rom I am waiting around 7 minutes before using my phone. Right now I'm back to my G2, which in my opinion feels better and battery last longer. I also dislike Sense but the camera is fantastic compared to the G2.
I have used Bulletproof 1.1, DoubleShot Lite 1.2.3, and MikTouch-0.7 and all had the same problem.

Yup, always wipe everything. As I got the phone used that limits my options for hardware issues.

Definitely a hardware problem. Multiple roms should not all have that same problem. Either your battery, battery connection might be bad. But with such a general problem, it can be nearly anything
(exactly why I don't like buying used phones)

Phone Powering off by itself Solved!
So I have bought several phones over the past year cause of this same problem. I take it to the service provider for troubleshooting and all they keep telling me is its a hardware issue. They do a hard restart and blah blah blah. Long story short. IT NEVER FIXES THE PROBLEM... BUT.... I realized it was the battery slipping loose. every time you place the phone down it gently slips out of place. Of course it doesn't fall out cause the phone has a back. So. I just taped my battery to the inside of my phone. PROBLEM SOLVED!!!! Did this with my Samsung Conquer 4g... and with my friends 4g slide. It stopped the mysterious powering off, Try it and see it if works for you! Hope this helps someone!

I actually have had a problem like this before with the battery contacts. It seems very snug in the 4g slide.

I'm going to say its a hardware problem but my phone has been on for days now, though I'm not using it as I'm using my old G2.
A part of me just wants to stay with the G2 but I miss the excellent camera on the 4g slide. Of course I need to find a use for the slide though. Gotta love turning a very minor decision into a big deal.

If you're going to go used . if you have your area supported in craigslist buy it from there. Then atleast you can check for full functionality before you fork any dough over. I dont think ive ever bought a new phone in my life and never got a lemon

I've bought most of my phone's used and never had a problem. I would get a new phone but my phone selection is limited due to the QWERTY and good camera I want.

My phone tends to turn off when connected to WiFi with WiFi calling on... or at least it used to with stock and the CM 7 kang, but I haven't tried other ROMs.
Since the CM 9 alpha just got WiFi calling, I haven't had much time to test for that yet.
Have you tried not using WiFi or WiFi calling?

Hi all,
I'm having a similar shut off issue, only mu phone is fully stock. No root, no s-off, and no rom. It seems to be completely at random either by using the browser or any app or no app at all(after I've set my phone down, I've tried using it only to find it shut off). I did a factory reset and the problem persist, though not as often. Any ideas? Thanks!

Did you have any luck getting a replacement?
Was WiFi calling on? (My phone would reboot even stock randomly when WiFi calling was in use.)

I did. Same thing happened with the replacement. I rarely use WiFi and I make sure WiFi calling's off when I do use it. I thought it might be an app but so far, it's turned out to be the battery. I got the phone in February so I didn't think it would go bad so soon. Got an Anker and been restart free since.

Huge Network Issues (TMO)

I just recently completed a move from Vegas to Phoenix. Upon arriving i saw that my mobile network just constantly bounced from edge to none to 4g to 3g and nothing ever above 2 bars. no matter where i go, thats the way it is. even when other people with TMO are right next to me and have perfect service. i finally bit the bullet and went into the tmo store and basically the guy told me that i had to get a new phone. My current rom is paranoid android but it does the same on AOSP MIUI and sense 4 viper rom. havent tried any others because i figure i have most of my bases covered there. ive flashed every combination of radio and RIL possible and it does the same thing. when i went in, they gave me a new sim card because they said my sim card was "2G" but seemed to pick up 4g just fine in vegas with 0 issues.
did my phone just really magically break while driving i guess?
another note: it seems worst when sending text messages, like ill recieve one with 2 bars of 3g, type it out, hit send, right after i hit send it just drops the service and says message cannot be delivered. i just have to keep getting it sent back and send it again until it finally goes through. this issue is very very frustrating. thanks for any help you guys can give me, i do want to get a new phone but need this one to work until i can afford it. oh yeah, newest firmware if that matters but i hadnt even updated it before i got out here, it was just one of things i tried to fix it. NOTHING has worked or even helped a little bit.

You and I live in different ends of the US but we seem to have the same issue. My wife has a Sensation also and has good signal most places when I can be right beside her and have no signal, just like right now, I will be lucky to get this to send. I too have tried several radios and RIL's also. I got some advice from mf2112 a short while back. I am just now going to look into it further. Check the pins that make connection to the back cover and make sure they all are making good connection. I am checking mine as soon as I get home, I am sick of not having signal when I know I should.

Hey guys i have an advice the same happened with me and i installed the official ruu with european radio and ril and it just went fine from there and after that i installed many roms(i lost the count anyway)it worked fine 4me try it out bestof luck

I just checked my connections and even lightly cleaned the dust off of them to see if maybe that was the issue. actually seems like it helped a little but not enough to solve the issue. it was definitely worth a shot though. might be placebo effect tho...

are you talking about flashing the actual RUU that says "mod edit: do not flash" or are you talking about the 3.33 firmware from europe? i flashed this firmware and it didnt help my issues. im wondering if i shouldnt try to go back to 100% stock or something this is very frustrating. the guy at the store told me "you know, when you flash things over and over sometimes stuff just breaks" which doesnt make any sense to me. every phone ive ever had i could flash as i please. and i wasnt even heavily flashing anything on this one until i started having this issue.

I have done exactly what the poster has done.
I have done everything... here's what I know
The issue is only from cm9 and aokp.. try flashog hyper nonsense and you shouldn't have issues.. problem is u lose all the aokp settings
It seems.like the issues flux in out.. one day it will work.. one day it wont.. sometimes I.wonder if the tower you are connected to.makes a difference
No,.it.doesn't break from.flashing it.over and over.. the storage is flash so it doesn't have a limit
