[Q] Why am I not getting signal at all...anywhere?

I just got a G2. perm rooted it. and everytime upon booting up it has signal for 1 second then literally just disappears and never comes back. can't choose mobile network or anything because it can't search for it. tried doing *#*#infor#*#* and it says GSM ONLY and everytime i try to change it to WCDMA PREFERRED it keeps reverting back as soon as i exit. the only way i've been able to get signal back so far is to connect to wifi and enable wifi calling, then after disconnecting i'm able to get signal and i'm able to check the WCDMA PREFERRED option but awhile ago i was on wifi calling then left my house and it was disconnected but wasn't able to get signal again.
can anyone help me with what i should do because although i might be able to get it back through wifi calling, this will be very problematic whenever i'm not near my normal wifi locations...
thanks for the help

Eh... I would try reinstalling a stock rooted rom.

Is it factory unlocked? Have you used an unlock code? Have you tried the full radio s off, super Cid thing?

I wonder if your SIM card is faulty, needs cleaning, or is just a bit loose in the socket.

This is what it sounds most like to me. Also try to install another rom since you have it rooted now and see if that fixes the issue. Make sure you do a Nandroid backup first though!

I never put an unlock code and I'm still on tmobile. I called them and so far I haven't had trouble with signal as much but my number doesn't show up under status in about phone settings...it just says unknown. Its only on this phone though, my n1 shows my number with this sim.

Just so we're clear.. Did this phone/sim combo work OK before your rooted the phone?

No it wasn't. For the past couple of days since calling tmobile, its been significantly better but today I did randomly have that same problem of no connection, but mostly right now my problem is my g2 not being able to read my phone number in "status" under "about phone" settings but it does on my n1. When I called tmobile they tried sending my number ota 3 times with no luck...

During the first 30 days you can go to a TMO store and get a new phone, pretty much "no questions asked". I'd go ahead and do that if I was you. Oh, go to a corporate store though, not a mall kiosk.
While you're there, get a new SIM, too. All free of charge.
If you still have the same problem after that, I'd try an exorcist

Is this problem solved now ? I got the same problem but have no chance to return it back.
If there is the way to solve it, could you please inform and share
Thx

My signal problems seemed to be resolved, at least for the past week. It was resolved by calling tmobile customer support and they did some tests. However, my phone not recognizing my phone number under settings> about phone> status, is still a problem. Even tried getting a new sim and still didn't solve the problem. Did numerous OTAs with tmobile that didn't work. My number still shows up on caller id and stuff its just that menu thing. Sounds insignificant but some apps use that to determine your phone number. Also, when putting my sim back into my nexus one, it does show my number...

Nevermind, my other problem was just resolved after reading a post in the cm6.1.1 thread. Settings-call settings-additional settings-my phone number.

[Q] 3G not working

Hey guys I dont see the 3g signal on my phone. I guess i went into ##DATA# and messed something without my knowledge. Now the 3g symbol does not at all come up whatsoever. Advice appreciated. Thanx a lot.!

I am actually from India! Using it on a indian service provider. About the guess yeah, I dont remember actually if i changed anything. I even flashed the phone to stock/custom rom. No use

Flashing stock ROM wont reset those settings. You will need to reset the activation on a stock ROM. I'm not sure of the code for that but its been in the treads a few times....
Which would be ##786#.....

Still no avail brother!

Is this device compatible with the 3g service your provider uses?

Yes it is. I have been using for quite a some time now.

Having the exact same issue. Not sure what caused it or how to fix it. I too am on stock rom

Have you contacted your cellular provider? If you changed some settings, most likely calling your provider to get the right settings will be your best course of action.

Alright,so over here in india we use nvitems (dump files) for evdo Else known as 3G. I tried everything but it doesnt seem to go back. Any way to make a phone go back TOTALLY to its 1st stage? When it came out when it was shipped? As in the whole parameters to be new. I tried flashing new parameters,prl, No avail. Just cannot see the 3g logo.

Any help?

We are probably going to need a little more info than that if you want help...

Agreed... ankurcshah you've given us very little to go on here. You have to remember that the ET4G your using is mainly a US/Sprint base device.
Have you rooted, installed a rom/moden... Help us out some so we can help you out.

As far as I know and someone else has already posted this... You can do a factory reset to bring the os back to a "out of box" state. But this in no way will effect, change or the dialer or radios. Those settings are set by the carriers.

Again, this is your original post. In it you clearly state that you "guess" you did the "##DATA# dialer code and" messed something with out my knowledge".
After rereading your original post again I'm thinking it really should have read this way...
"I went into ##DATA# and messed with some of the settings and didn't really know what I was changing." See the difference???
Those setting in "##DATA# or set by the carriers... They are there to tell the radios on your device how to communicate with and what frequency to use for the towers your cellular providers uses.
I'm going to assume that when you got your ET4G you had to contact your cellular provider to get it setup to use their service, right???
Questions:
1. If not how did you get it setup to see their towers???
2. Did they (provider) give you some kind of codes to enter in the ##DATA# settings???
3. If they did, do you still have them and have you tried that???
I've said this before... I really think you need to contact your provider and see if maybe they can re provision your radios.

Nope, I just needed the dump file for the 3g to work, 3g works on my dad's phone and it doesnt on mine. I use the same dump as his. Still? Wierd
Questions:
1. If not how did you get it setup to see their towers???
I just flashed a prl
2. Did they (provider) give you some kind of codes to enter in the ##DATA# settings???
nope, I had set the msl to 000000
3. If they did, do you still have them and have you tried that???
They are not aware of such a thing also.

I tired they don't understand "reprovision radios"

As you were saying about the out of box state? Could you elaborate a bit more on that. I just need to reset the data settings of the phone to the state in which the phone had come. In the sense as in out of box.

The reset I mentioned is a "factory reset" ... But like I already posted... It will only delete all of your user data and reset settings like wifi, email passwords...
It won't reset the radios...
If you had already flashed these files to get your phone working when you got it, Don't you still have them???

HELP please...Problem regarding very poor signal after root?

Hello. I finally decided to root my galaxy s3 a few days ago. After I did so I downloaded some themes, ad block, etc. the normal stuff. The next day I started noticing something odd with the phone, such as very poor data connection (I can restart the phone and it will say I am on 4g for a minute or two although the connection doesn't say the same, but then it will either go to EDGE or give me no connection at all.) and poor network (says I have good bars but texts don't send often and take 10 minutes to receive; phone calls drop.}
I took the device to the AT&T store and got a new SIM card and that did nothing. 45 minutes of "support" did even less for me. I unrooted it, factory restored it, nothing.
I am desperate, if anyone would give me a workaround / fix, it would be greatly appreciated. Thanks.

Not sure. Did you check your APN settings? Did you flash any ROMS, modems or kernels at all?

I don't think so...I did everything this tutorial on galaxyroot told me to do...would link but can't.
Sorry I am not too experienced with rooting
APN looks fine...Then again I don't know what I am looking for lol. It says ATT PTA and it is checked.
I did have apex launcher I don't even know if that was a rooted app though lol..........

Thank you, now for the QCN..........I will be very happy when this is fixed lol.

So whenever I try to create a QCN I am unable to find it in the location I placed it, and I have hidden files visible. When I try to slide it to a different folder it says the file doesn't exist anymore. My phone has moved to "Unspecified" in devices and printers and I am unable to access any of its files even after trying to reinstall drivers multiple times (it gets stuck on the 5th one...network something...). Does anyone have any suggestions on how to resolve the problem with not being able to access my phone?
Ok I figured out how to access my phone and I think installing a new modem fixed it.....we will wait a couple hours and see.

[Q] Fails to automatically connect to mobile data after Wifi

Does this happen to anyone else? Quite often if I've been using the N2 in my home, when I go out and about my phone will not be connected to mobile data (3G) and I have to toggle airplane mode for it to kick in?

Not had this myself, sounds like the cellular connection is going to sleep and not waking when your note 2 polls for a connection. Are you on a stock rom or a custom, can you post your android version number as well, will help anyone else who posts who may have more information for you.
If your rooted you could try pulling a log at the time you switch connections see if that yields any useful data.

Same here on a german device. I use manually select the Provider. Then it connect. Thank you for the tip with the airplane mode. But I search a way to kick this big. In a german forum a member says that a Fullwipe helps.

Can anyone tell me what to look for in order to create a log? (I don't expect a tutorial just someone point me in the right direction).
The problem is intermittent.

Give this a go, should allow you to create a log during the time you have the problem then you can see what android is or is not doing at the time.

Not something I have had myself but my gf has this same problem with her gs3. After having a look around our seems to be fairly common on the gs3 so any help with a fix would be great. I can only assume that it's something that will be fixed with a fw update from Samsung.

I have the same issue and so does my girlfriend on her SIII.. Can be really annoying as I might leave somewhere with wifi connectivity expecting the phone to automatically connect to 3g and I miss things like whatsapp messages with no warning :/
When I realise I do use the flight mode trick to fix it but it's annoying that it happens.

[Q] Help! Phone is LOCKED

I use pattern to unlock my Galaxy S3, but my son played with my phone and accidentally input too many patterns and make my phone only can be unlocked by signing into google account.
My wifi and mobile data status seem OFF. I am thinking maybe it makes my phone unable to connect to the Internet and sign in to gmail. I tried to call myself using another phone but the phone did not let me go to the home screen to turn on the internet connection.
Is there anyone know how to solve problem? And if I need to factory reset my phone, how can I do it?
I'll be grateful if there is someone who can help
