No Networks found - AT&T Samsung Galaxy S II SGH-I777

I just recently rooted my phone, and abit confused getting the cellular network to work. When I type in *#06# in the dialer my IMEI does show up as the sticker says behind the battery. I have also flashed all 4 radios provided here (http://forum.xda-developers.com/showthread.php?t=1982571)
Not sure what the next step would be. (Been searching the forums all day)
I would like to take the phone with me overseas and ny help would be much appreciated
Thanks in advance

No reception...

Okay..
So i'm walking and stumble across a G4 Wizard on the road. Now where i'm from, South Africa, there is an option to call the operator and black list the phone.
I have CID Unlocked the phone with lokiwiz 3a and installed a new ROM (BlackDiamond 2.0) to try jack it up.
But when I inserted the SIM Card, the phone wouldn't receive any reception what so ever from the operator.
Does anyone have a clue on how they can get the phone to find signal.
I'll sell it and give u 50% of sale
is it overclocked >276 mhz?
Nope it isn't. Has that got anything to do with the phone been black listed?
What I think happens is that the networks block that specific IMEI number and make the phone void. Is there a way to change the IMEI number of the phone. Like i said, i THINK that is what has happened so I could be wrong...
Did I get it right you found the Wizard on the street and you SIM unlocked it?
If I lost my Wizard I would appreciate very much to get in back - even just to get back the data and contacts etc ...
I would have done that if there was any DATA on the phone. The phone was brand new and had no contacts/calendar notes - zip! And plus I had waited 2 days for the person to call me and no one called.
Now back to the issue......
If the phone was blacklisted then company's can do 1 of 2 things, not send a signal to the phone at all or just not allow you to make calls on the phone at all but the phone would still show a signal. The other possibility is that since you found it on the road maybe the phone had fallen and hit the ground hard enough to detach the antenna. There are ways around a blacklisting, but since that info can be used in the wrong way I don't give that info out. That info however is here on xda if you look in the right places though.
Phone is in perfect condition. Don't reckon its the antenna that has detached at all.
I've searched everywhere on xda and still have not come right. Info can be used in the wrong way? Doesn't make sense. Please PM me and try help me get it working, otherwise I just might as well just throw the G4 in the bin since it's of no good use.
Is it possible for the network to identify a specific IMEI number? If that is possible, maybe they have just black listed that specific IMEI number. Is it possible to change that figure?

Can anyone help? - No Signal

Hi folks, can anyone please help me with this problem?
My brother in law has asked me to look at his S740. He has tried several o2 SIM cards (UK) in this phone but always gets told there is no signal.
Not only that, but there is a symbol where the strength meter should be that isn't documented in the user guide.
He has also tried my o2 (3G) sim and a Vodafone sim, both UK.
Any advice gratefully recieved. We have tried several hard resets also.
Thanks
This means it's looking for signal. My guess: Still SIM-locked?

Not sure if it's SIM locked as there is a menu to select which carrier to use.
It reads the SIM correctly and sets it all up for o2, but just doesnt get any signal.
Does anyone know where the GSM antenna is on these? Maybe its a bad connection.
UPDATE:
I've had a mail back from HTC that recommends I send it in for repair, lol.
Now do I take it they are robbing buggers or do I take it that the icon is an indicator of a hardware fault??
Hmmmm, dilemma. lol
Are there any more suggestions on what it may be?
Has anyone successfully taken one of these apart?
it may be because of a hardware error...try to connect to a wifi network...if it impossible to find a wifi network then it is due to a harware problem.Most likely because the FR coaxial cable is out of its possision...download the service manual and see how to fix it.

Hi sasiskas, it conects fine to my wireless network at home. I take it from your response that the cable serves a double purpose.
I downloaded the service manual so I could take a look, but only got as far as removing the 4 screws at the back. lol, I couldn't figure out how to get it off, lol
I'm still stuck at the assumption that it is indeed SIM locked, and so will try to find a suitable card to try out.

Try contacting with your phone's provider (shop,e-bay seller whoever it is) and ask him details about the sim.Good luck.
hey

Thanks. I have tried the same but just keep getting a vender ID, (lol spelling), error.
I would appreciate any input whether you have success or not, it just may spark an idea off.
I cant get in touch with any sales or provider as it was gifted to my bro in law. He's not that bothered about it but would like to have it working if he can.
Thanks folks.
Hey! I think I know the solution to your problem...I had exactly the same problem when I hardReseted my phone.
Go to "Start-settings-Phone-Band Select"
and then select
1.Network type : Auto
2.Band Type : "Euro" if you live in Europe, "US" if you live in USA , or "Japan" if you live in Japan.
Good luck...Let us know if it worked!

Yes that is a good suggestion because the phone will display that icon if it can't find a *usable* network, be it that the SIM doesn't allow it or if the bands don't match the selection on the phone or the bands are not usable by the phone hardware etc.
I would suggest downloading & running HTC Field Test (fieldtest.exe) with & without a SIM installed, with each network & band setting & see if it shows any towers or signal. (Normally you want Auto for both but you may not have that option or you might prefer to set to a KNOWN working band to conserve battery & minimize searching) If should show something even without SIM or with SIM lock because it's supposed to support emergency calls either way. If it shows signals with SIM but you still have same no service icon then it's likely SIM locked (although the phone should alert you to that fact) so odds are the phone hardware, rom or settings do not support whatever signals are available to you. (Btw if field test shows N/A for all the values you need to app unlock your phone)
Hope that helps.
Bill
can you share a link with HTC Field Test?Thnx
Search is your friend.

Hey all I'm having a very similar problem.
Had my HTC for some months now but in the past few days I've found that my network signal is becoming very unpredictable.
I'm also on O2 and I used to have a pretty contstant H (I presume HSDPA) connection.
Howeever im finding now the phone with go from H to 3G to GPRS to E to no signal in the course of 5 mines and round and round again!
Its very annoying as it means I cant make / received calls or texts fluently and even cut me off on a phone call too.
However usually on phone calls it will keep me connected ok till I hang up and then go to no signal.
I've checked the wireless and it is picking up networks..
Any other suggestions? I will try the field test tomorrow...
PS I know its not the network as my work blackberry is O2 and is not having this issue..
Cheers in advance!
Well, just to close my input on this thread.
I tried various ROM's available from this site and none worked.
I did try the band selection settings but still a no go.
I did have limited success but overall, nothing. The phone has now gone back to the person who asked me to look into it and to my knowledge he is going to sell it to one of these phone reclaim companies.
I did check and one place, I think through the post office, is offering £80 ish so not bad I suppose.
Anyway, thank you to all who have made suggestions and wotnot. Personally I'm still happy with an old Nokia 6300 and my Wizard (Mini-S)
Thanks folks.

[Q] Atrix problem "network with limited service found"

Hi,
I have strange problem with Atrix, it's registering to network then it is showing "network with limited service found. do you want to initiate a network search".
Mobile network is connected, I have good reception, I can use Internet access over that network, however cant make/receive.
Stock firmware, no changes.
Any information much appreciated.
Rob
That's odd. I guess T-Mobile is compatible with the atrix in the UK?
If your phone is completely stock, maybe Moto or your carrier could help you with it if nobody on here can. I'm not an expert, but if you just got this phone, then if you wouldn't mind doing a factory reset, that may squash any problem. Another thing that it may be doing if it's a new phone is try to update itself to a newer build? When you go to wireless and networks and look at the list of APNs, what is listed and what is it currently connected to?
Hi
Thank you so much for your replay. Unfortunetely i've done all those.
I think I can do much more than give headaset back to the shop as not working.
Regards,
Rob
Ps. Funny enough I'm sending this from Atrix on 3G connection but still cant make thw call.
Sent from my MB860 using XDA
Mystery solved, I have bought a "blocked" phone.
I called Orange UK to ask about status of that IMEI (as that was Orange phone), and very nice lady told me that phone is blacklisted with "lost or stolen" description.
So next time when your toy cant login to GSM network but working fine on 3G/GPRS please first check is phone is not blacklisted.
Case closed.

Rob

[Q] SGS2 no signal 3 network

Hi all.
ive been floating around the forums for some time as an unregistered user but i now have to resort to posting for help.
fist of all heres my details
Android version 4.0.3
Baseband 19100XXLPQ
Kernel 19100XXLPQ
Build IML74k.XXLPQ
ok so first of all id like to know if it matters that the serial on the phone does not match that on the sticker behind the battery although the IMEI number does,from what ive read on the forums this may be because i flashed a non official ROM?
when i originally flashed to ICS the signal was poor but i still used the phone and now i have no signal at all at home,
if i try and dial a number i either get `mobile network not available or not registered with network.
ive flashed the phone with so many roms,kernels and modems now that im in a complete mess with what ive actually done.
i checked with my provider `3 UK` if the phone was/is blacklisted but its not,ive had the sim replaced with a new one and also tried another 3 payg sim.
im not normally one to give up but i admit im getting close to it.
in hind sight i wish id taken a full back up whilst on gingerbread or even never upgraded to ICS in the first place ..ah well
so my thanks in advance if someone can help me and apologies in advance also if ive missed any information out.
cheers
theredi
just to add to this,
i just stood outside and scanned for networks,the 3 network appeared but when i select it it says:
your sim card does not allow a connection to this network
i spoke to 3 just incase its their end but they insist its nothing to do with their sim and is my phone thats the problem.
this is a sim only contract by the way the phone did not come from 3.
so u hav no signal??
imei may got reseted..
flash stock rom an c....
jus my sugettion wen in xda don float get registered
i have no signal or at best its extremely poor,just enough to scan for a network.
what do you mean imei may have been reset? the imei is the same as it was originally.
and ive flashed lots of stock roms and had no luck as of yet.
just tried android 2.3.5
Baseband 19100XXKI4

I meant have you entered the networks settings as supplied by 3 or are you hoping its auto set up after multiple flashing you may have wrong CSC .
jje
so is ur prblm solved did u enter settings as jje said,,,,if ur phone is working fine now,then post
no my problem is not solved however i have some updates after driving around the area (going to the pub)
ive not changed any network setting as i see nothing there to change.
i managed to get a few signal bars and searched for available networks,3 was ther,when i selected it i got this message:
unable to change networks while data service is in use.stop using current data service and select another available network?
i said ` ok`
...registering on 3...
...registered on 3 network.
after this i was able to make a call.
i noted some info at this point incase it has any relevance :
Signal bars: 2
signal strength -109 dbm 2 asu
Mobile network type:9
service state: in service
network:3
phone number : unknown
this happened in one spot on a 1 mile journey.
and now im back at home the signal is back to nothing.
the 3 signal in this area is normally pretty good so something isnt right
the info now is:
Signal bars 0 - 1
signal strength -111 1 asu
Mobile network type: unknown:0
network: unknown
service state: out of service
mobile number:unknown
ive always had a good signal at home and for all of the journey i just made but now it seems to only pick up in a very limited spot.
ive not entered any network settings at all,like i said theres not much i can see that needs changing?
thanks for your input guys its really appreciated.
I don't know if its your issue,but I had several phones on 3 which all had awful signal strength- I just changed to a different network.
Sent from my GT-I9100 using XDA
3 isnt the problem here,everything was fine until i started fixing things that arent broke, and im old enough to know better :S
ive been with 3 for as long as i can remember with lots of different phones and never had any signal problems where i live up until now.
still unsolved
Weird. I have exactly the same problem. except Im on irish network meteor. same symptoms. ben on ics for ages, flashed a cm9 rom. nothing unusual,bam. no signal or very little.
try flashing NEKF2 or NELP3 modem
I have issues with 3 UK too, mainly because I like having the option to switch back to 2G to 3G to H, but 3 doesn't like the idea of GPRS so that's out the equation Plus, the network is pretty piss poor. I'm looking for a better modem, in all hope.
Baseband: XXLPW. Running ICS 4.0.3

No signal

Hi all, I recently got an S4 SCH -I545L from a friend to help him
But I faced an isue with it, it receives no signal at all, It just shows an icon with a circle inside in diagonal
At first the I thought it was siölocked so i strugeled to get into service mode using shortcut master for the conventional dial method didnt work. But to no availm after following the desimlock procedure, still nothing(Seems like it wasnt even simlocked since i found no NV golden backup)
Then out of a sudden when explorimg secret codes i found out that my IMEI says unknown, so i tried every possible thing to fix tha
I tried to install Xposed so as to install Xposed IMEI changer, but I was unable to install xposed for various reasons
Then i tried a lot of things i found on the web, but still nothing, seems like this issue is very complex
Im running android lollipop 5.0.1
Regards, hope someone can help
Come on, s o no one can help me out here ?
Really?
In the whole XDA community?
This is really sad
I don't know if my problem is exactly the same as yours, but I also have a no/very low signal after adding an AT&T SIM card to this phone:
http://forum.xda-developers.com/gal...rizon-samsung-galaxy-s4-sch-1545-att-t3459764
So far as I have googled, my IMEI number is clean.
EDIT: For your particular problem, it might be helpful to know what carrier SIM you're using and whether that SIM is specific to the phone or not.

I used a SIM tool app to verify SIM card, and it said it's locked to Verizon, but a lot of properties are listed unknown, so it's definitely not connected to the network
I think it's a CDMA/LTE phone but I tried and none works
