I have been searching for 3 days trying to find the problem. I have an AT&T Galaxy s 2 that I rooted using the Zedomax root through ODIN. I unlocked it to use for my T-mobile service. Everything was working fine for months. Then one day I woke up to use my phone and there was a circle with a cross through it. I am not able to call out or even get a data connection. So I tried flashing back to stock no root and same thing. I put a AT&T sim in and it was the same thing. Flashed back to root several times and I still get the same thing. I checked to see if my radio was on and it was fine. Did Either Service just block the phone? I don't get it. When I leave my house I get bars but no connection on both data or service. Yet I get all kind of texts . So why wont it let me call out or even use my browser if i go down the street and it says it has service and is getting texts? I swapped phones and works perfect so I know it can't be my SIM.
Any help would be greatly appreciated!
Thanks.

DId u try calling T-mobile? or AT&T about the issue?
Well I'm on a "no contract plan" and buy my phones cash. So no warranty. So Zedomax is bad?
Maybe flash a radio to it. I've noticed that I lose service with some roms occasionally. But when I do, I just flash a radio and it seems to fix it.
Sounds like a bad APN setting to me.

Very bad. Its well known to cause many problems on peoples phones. They usually come here after messing up their phone from his website which is no bueno and annoying. Stick with xda from now on, it won't steer u wrong

Call your service provider and verify your APN settings are correct.
From my own limited knowledge. A circle with line means no signal. Bars without a connection type icon means a signal but no service.
As far as useing the zedomax rooting method, as per the OP if it was running fine for monrhs, that clearly isn't the issue.

I'll try flashing a radio and see if that works. .
i have checked all my APN settings and everything seems ok to me. I have hard reset multiple times. My data packet shows on. I also checked my settings to see if my radio is on and it says yes. My Iemi number shows. I'm so confused what could be wrong. It won't work with both ATT or T-mobile. Should work no matter what considering this is an ATT phone.
hey guys my galaxy s2 is currently on shostock2
and the imei is there and everything i get like 2 bars as service but it says emergency call only and i tryed GS11_repair and hc-ktool
i just cant figure out why i get no service and its unlocked i have a tmobile sim card in it but i cant make calls or nothing everything else works fine except it wont connect to tmobiles mobile network i think in network operators tmobile doesnt even show up only at&t
if some one can help me resolve this issue it would be greatly appreciated thanks you
Go under mobile networks and do a carrier search and see if T-Mobile pops up. Are you in a good coverage area? If it says emergency only then you're probably connected to AT&T towers (which shows your radio works, so that's not the issue)
settings -> more (under wireless and network) -> mobile networks -> Network operators -> scan for networks
I did man only at&t shows up

Yeah, that just sounds like you're having crappy T-mo coverage. You could try flashing a different modem.
I just did I get bars but its still in emergency call only
Sent from my SGH-I777 using xda premium
Even though you have bars, doesn't guarantee that you are on the T-Mobile network. You can also get bars on other networks if T-Mobile isn't available. This has happened to me before when I drove off in the mountains, and only AT&T was available (I'm on T-Mobile), and I got 4 bars, but it still said "Emergency Calls Only" because I was on the wrong operator.
the problem with my device I never get more than 3 bars

Hey. Yani. Did you solve your problem?
Because I have same issue as you have.
I heard from one of my friend that upgrading gingerbread to ICS might work, so I did that as well. but still the same.
And just to let people know, I am not in the crappy tmboile coverage area. In my other phone, I get five full bar reception with same tmobile sim card.
Any ideas?????
Different phones have different radios, get different amounts of service.
Unless your 'other' phone is another i777, theres nothing to compare.
does it really matter how good of service you get when you only get edge?
APN settings
Did you input the APN settings for T-Mobile? I unlocked mine and run it on Straight-Talk and I had to manually input the APN setting to get it to make and receive calls. Just speaking from my personal experience I would choose Straight-Talk over T-Mobile. You still get the same service as AT&T but its only $45 a month for unlimited everything including data. Just check your APN settings man. Make sure your T-Mobile one is selected if you've already input everything.

Yeah, dude. It does matter to me.
I am trying to set this up for my old man, and he really doesn't care about 3G/4G stuff.

Yeah. I tried that and getting a little bit better service. I will try it on Monday because at work see if it is better.
If it doesn't, I guess I have to sell this phone, since I tried almost everything I could.
Thanks for letting me know about Straight-Talk, but I have to stay on T-Mobile. I had a deal with T-Mobile for $100 unlimited txt and data for 4 lines. So I can't switch over for 2 yrs....
anyway, thnx for the advice and will update on Monday night.
Any Resolution?

Hey shpchunjae, did you ever get this figured out? I'm fighting the same problem now (trying to get my i777 to connect to the T-Mobile network) and I'm not getting anything - voice, text, or data. The SIM card works in another T-Mobile phone, so that's not the issue.
Thanks!
Hey,
I was playing around with a few Custom ROMS today, and my mobile data stopped working. The APN settings are correct. I have flashed multiple ROMS but no luck. Even stock ICS ROM. I think I have the wrong modem/baseband combination.
My phone show H+ or 3G icon, but as soon as I try to use the internet, it vanishes. Wifi works fine.
Any ideas?
Seems like incorrect apn.. but you already say it's correct..
Try to Flash the stock modem..

Yes the APN is correct.
Could someone possibly tell me which firmware I should flash? I purchased my phone from Pakistan, but I'm not sure which region it is for. Will that make a difference?
Something happening with this phone. I had the same issue a few weeks later.
I tryed almost every modem available unsuccessful. Just my local carier can solve. I didn't known what they did, but solved until now.
Although your apn settings may be correct, they may need updating.
This sometimes happes in the uk.
Maybe if you tried deleting the apn settings out and then ringing your carrier network up, and asking them to sent your correct apn settings to your phone, maybe this could help.
Its not a dead cerainty but always got to be worth a shot mate

Had the same issue with my GS3 (I9300) after switching from those Straight Talk Bastards to AT&T:
Whereas Straight Talk simply f*cked up b/c of a collapse of their data network, so I assume (with nobody at ST saying a word for 2 days, of course.. ), it turned out that AT&T actually had deleted my new account - by mistake - after just one week of 'happy browsing'.
A trip to the local AT&T store solved the mystery and got me up & running again.
Unfortunately, though, it took the AT&T folks a while to figure it out, as they are not used to unbranded/international/ unlocked phones wanting to join their US network. (Don't even try to solve this over the phone, if you have a choice).
Kudos to the AT&T staff, though, as they got the problem resolved eventually. It definitely helped a great deal that my phone had been working just fine on their network just a week ago, so I was able to stand my ground and insist that the problem was at their end.
One of the reps - apparently without a clue - tried to tell me all sorts of BS, e.g. that the I9300 would not work on AT&T; that some Samsung phones supposedly don't work with their network... bla bla blub blub...
Fortunately, I knew better and told him so. Otherwise, he may have successfully gotten rid of me; making me search for the problem someplace else (a.k.a. giving me the run-around or making me chase my tail, etc. :banghead: )
Thanks to xda (and the Internet), however, I had all the knowledge necessary to make sure they get it back to work. Now I'm browsing the web again with 7Mbps Down/3Mbps Up speeds, using AT&T's really fast HSPA+ network here in the Chicago Northern Suburbs (close to O'Hare)... Yay!
Good Luck with finding the problem with your data loss issue!! :thumbup:
P.S.: Let me know if you need my APN settings; just for comparison (.. in case you are in the US, too).
Cheers,
AA

*****NEW PROBLEM******
: I'm stuck on edge!! with no way of getting into the service menu to force GSM ALL or whatever.
I've checked all the apns, and I've tried flashing other radios.
What gives?

Hey,
I have a rogers locked note i717R
I installed TWRP/Rooted and flashed ptmr3's |ROM|| JEDI || Sons Of Android || Buid 4 || 3|28
Before flashing, I was on official ICS for Rogers.
I have a registered, active SIM (Works on another phone) Rogers SIM and I'm using a Roger's ICS Radio Rogers ICS RUXLF4 modem
Yet, I have no service.
APN's are already pre-configured from the SIM... and are there...
But no service/signal at all.
Any ideas guys?
Flash a different modem to eliminate that. I would suggest the LF6 for at&t, but it will work on the Rogers bands.
No service at all? You mean phone and data? If phone signal is not working then I would reflash the ROM.
Sometimes my signal just drops for no apparent reason. Reboot and it's back. Weird but it happens.
Maybe try under network mode settings? See which band it is trying to access first?

Three great suggestions, OP. Did any help?
Heehee, probably put the sim in backwards. Can't say I've never done that. :silly:
Oops, me neither.
Hey guys thanks for the suggestions.. turns out it was a damaged SIM port.
I tried literally everything before taking it to a cell phone repair shop - they confirmed it was the SIM tray that was damaged. Oh well.
Did they quote you a price for the repair? I'm pretty sure its beyond most of our skill levels.
Actually ranger, it turns out it was the antenna that was damaged, and not the SIM tray.
Either way it was $60 to repair it
I have everything up and running. However, I'm stuck now on Edge for some reason, with no way to get into the service menu to force 4G or 3G =/
Okay so I somehow fixed it by messing around with APN settings and #*#*4636*#*# Lol
Not sure how but its working

Well, antenna makes sense. A while back several users developed butter fingers and antennas were coming loose left and right. They just had to push in the module a little to correct it. But we knew it was the antenna module because gps wasn't working either.
is it possible to have a phone flashed badly or wrong? My Samsung Galaxy S4 was originally a U.S Cellular device, but was flashed to Verizon Prepaid. I basically have NO 3G. If and when the icon pops up, the minute I try to search or do anything it disappears.
My phone calls are fine, but my data is averaging 1X to nothing at all. Sometimes I cant even get a picture message out. I is driving me nuts, Especially when your paying for a service you cant use.
Was it possible that it was flashed wrong or bad? or is this something else. I have been trying to get it taken care o by Cricket King (ebay) but I think they think its on my end.
Any help or advice would be appreciated. Should I have it re flashed
Hmmm....I'm not a developer, but I do troubleshoot. Are you using Verizon SIM card? I believe once it's active and inserted you should have full functionality.
Sent from my SCH-I545 using xda app-developers app
I'm no Dev either, but did you set up the APN settings right? I would assume since it was flashed to a different network you would need to set it back up to work on the Verizon network. As for what those settings are I'm not sure. I've always been on Verizon and haven't had to mess with that stuff

Usually it ends up just being the APN's or the sim card. Since these phones are already unlocked it doesn't take much to get them going on another network

Well the guy who flashed it said he would probably have to change the PRL? Does this sound right?
NOTE** I am not using a SIM card (I don't believe ) Does this sound right? It was originally set up for U.S Cellular, bit was flashed to Verizon prepaid

Well I don't know about the PRL much myself. I know my sprint s4 needed the prl updated from time to time but that's sprint.
And your sure your not using a sim? I'll be honest I'm not really sure about switching carriers and all that. Just from what I've read on here I've seen many people do it fairly easy.

You must be using a SIM card because both U.S Cellular and Verizon need a SIM card. But to update the PRL type in your phone *228 and it should come up with a message saying it has been updated. Even though 4GLTE devices automatically update. Also, I would go into Settings, Connections, More networks, Mobile networks, Access Point Names, and make sure there is a green dot next to Verizon.
