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

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

T-Moblie service issue?

Just want to know if its just me or other people also. Lately even when I have service I don't actually have service..... Internet won't work/don't get texts I have to restart my phone to get it working again. Just want to know if it my phone or the service. Im running on [ROM-Leak][ODIN] Gingerbread 2.3.4 T959VUVKG4.

I had a similar issue coupke if weeks ago. Lasted about a day here. do you have the problem when using wifi too?
Sent from my SGH-T959V using XDA App

No I have no issues with wifi.. This has been going on for about 3 days now... it pissing me off....

You could try flashing another modem and see if it gives you better results. It might just be that KG4 isn't good for your area.

um go To Wirless & networks then go to Mobile Networks Network operators and hit search now.. and when tmobile comes up click on it... try that see if it works

i don't know if this is considered a service issue or not though, but i did have a couple of calls that did not go through and i'm on Valhalla 1.3.2.

Anyone else you know in your area on T-Mobile? If so are they having an issue? If not, definitely turn off the phone, reseat the SIM (if it's old, go get a new one), then see if it's better. If not, try what bkoon said. Let us know how it goes.

I'm still new to this so I don't know how to flash a modem/what exactly a modem is but I will look it up and see.
Also I didn't say it in the OP but this happens randomly. I sometimes go for almost the whole day without it doing this and sometimes it happens 10 mins after I turn on my phone.

If she's having a similar issue on a totally different phone it would seem to be a T-Mobile issue. Does it only happen in a certain area (your house, places you go/hang out, etc.) or all over the city?

Ah, I misunderstood. I thought you meant she has the same issue. What about doing a factory data reset & also reseating the SIM? Barring that, maybe flash a new ROM onto it to see if that helps. As bkoon alluded to, some modems (the part that talks to T-Mobile as well as wifi) work better in some areas than in others. Flashing a different ROM via ODIN would give you a different modem.
If you just want to flash the modem itself via ODIN, take a look in the developer forum (http://forum.xda-developers.com/showthread.php?t=1192436). You open ODIN, put the modem file in the "PHONE" location, and hit start.
If you need help, let me know & I'll help in any way I can.

I have to admit I'm CWM stupid Iv'e only ever flashed dsexton's Adrenaline Shot from CWM. I've never flashed a new ROM that way. I imagine it's the same as flashing any other ZIP, though. Tell me what steps you followed & where you're stuck & I'll do my best to help.
I'm more of an ODIN guy, but that's because I'm fairly new to this too.

Well the thing is I have full bars and even says 4G but it acts like I have no service(also this only started recently and I used to never have problems). It hasn't happened since I installed a new ROM yet but I have only had the ROM for about 5 hours. I am going to try out modems also to see if I can get better reception in some areas, but I have never changed the modem before so we will see how it all goes.

Sim card not allowing connections? [Help]

Flashed a few roms on my phone and never bricked it whats so ever. It shows the IMEI, how ever it doesnt match the IMEI it have on on the back of the phone. The phone came with 2.2.1 Froyo and i upgraded it with ODIN using KJ6 2.3.6 GB rom. I can connect to wifi and such. It's not the sim card cause it works with all my friends tmobile phones. I get bars on the phone with the sim card in it. But when i attempt to make a call it says "Not registered to Network" i went to Settings>Wireless and network>Mobile Networks>Access Point Names, i went there to do the APN Manually i tried setting it to Default and it didnt help either.
Anyone know's how to fix this?

Thanks for the quick reply, Does it have to be exactly 10mins? Not to sound like an idiot.

I'd say at least 10 minutes, going longer won't hurt.

Alright , Im giving it 20mins. Hopefully it works. It's been too long and i'm starting to give up on this phone.

Still having a problem, You know any other solutions? I don't wanna have to pay for a new phone lol. If you do can you have it in FULL DETAILS. Cause i want to make sure i have have every thing correct.

I got all day to try to fix this. I don't want to try reflashing things cause i don't know if i can mess it up or cause more problems.

So.... you have flashed a few ROMs..... meaning you have at least ONE nandroid back up from when the phone worked?
If you do... you are good to go. If you don't..... good luck to you. You have what sounds like a generic IMEI.

Well i don't, didn't know i have to. So in other words it's impossible to get this phone back on?

I had the same issue with my phone, it just wouldn't stay on Network, and the SIM would go back and forth from being recognized or not. I flashed back to stock and it still didn't work. The ten minute battery pull was suggested in another thread and a few people swear it works. Mine played up before this was suggested so I never tried it.
I had the same thing happen with my wifes phone and all I could link it to was the Kj6 modem...see link below. I reflashed the whole ROM and it came back.
With my phone I just called T-Mo and told them that since I upgraded to 2.3.6 via Kies that my phone wasn't working properly (Technically true, but a little stretch). I flashed Bhundvens 1click to stock, factory reset, etc...etc... then paid $20 and got a replacement phone via UPS in about 4 days.
I not saying you are having the same problem as I did, but it sounds very similar.
As a side note, the replacement SGS4G (refurb) they sent me absolutely blows my original handset out of the water when it comes to signal strength. I get solid 4G speeds of 5MB+ in my house, where before I only got patchy edge. I was amazed at the huge difference in performance between two supposedly identical handsets.
I hope you can get this remedied without an exchange, but you should be able to get a new one for $20 as a last resort.

Back ups are suggested all over this forum. Now you know. It is not impossible... google 'generic imei' and look at the dozens of ways people have had success and failure trying to remedy it. There are a ton of threads in the SGS 4G forum alone.
And whether you fix it or get a new phone... make a back up of your efs folder FIRST thing along with a nandroid back up. It will save your ass if this ever happens again.

Atleast i managed to Flash and root the phone with out failing nor bricking the phone. Even though it was my 1st time. Majority of new comers get there things bricked. But anywho yes, ill always make back ups for now on.

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

no signal or data after ics install

i have an issue. i cant get any signal or data whenever i flash either an ics rom or jb rom, but works perfectly fine with gb roms. back when LC's v4 of his rom was out, i was using it with no problem. after that thats when it started giving me problems. ive tried typing in the apns manually and everything, it doesnt stick. sometimes messing with the phone, like turning it on/off or switching airplane mode on/off, would some times cause it to get reception or doing the network operators thing in the mobile setting will give me reception but no data. im currently on cm7, and ive tried every ics and jb rom that we have out and its the same thing. ive checked the leads and sim card and doesnt seem to be anything wrong. id unroot the phone and start from scratch but i dont have a working vol+ button. and dont know if the carrier matters but im running on simple mobile. if anyone knows and/or can help, id really appreciate it. thanks

I've heard people have similar issues on simple mobile. Probably a problem on their end. Also if your volume button is fail then who knows what else could be going out. Bad devices usually develop more than one issue when they start to go.

Oh okay thanks. Guess I'm gonna stick with gb till I change phones.
But the for the reason my volume up button doesn't work is because it got some water in it when putting on my screen protector. Just wanted to throw that out there

Maybe too much water got into it and fried another circuit related to data and wifi? ics roms are pretty new and still a bit buggy... which ones have you tried? I'm using xgs-series 2.3.9 with no problems as of right now.

The button problem happened before. I've tried all of them and it's the same thing. Haven't have issue with wifi or on gb, and I've been able to use ics up until LC's ics 4. something. The only thing that works is the network operater thing in the mobile settings. I can run on tmobile with no data, but once I shut off the phone it'll either have no service or randomly say to insert sim. I'd try a att sim, but I don't know anyone with att.

When you say you've "typed in the APN manually and it doesn't stick", do you mean the phone isn't saving the information, or that it only gets reception for a short time?

The phone isn't saving it.
