I have international unlocked G Note which I got from India. My problem is whenever I turn off the phone and turn it back on I get "Emergency Calls Only" error for like 2-3 minutes and then I get the signal back. I have flashed many modems / roms (currently I am on the latest CM10 nightly / hydracore kernel with XXLRK modem) and the problem is still there. I've also noticed that after rebooting the phone under APN settings it always go back to "vodafone NL" and not my carrier's APN no matter what modem I have installed. I will appreciate your help guys.

I broke my old Blackberry and a buddy gave me an old Galaxy Ace that was locked to Koodoo, I have rooted, unlocked and now have the phone running on the Rogers network.
I have unlocked my phone and flashed many custom ROM's. The problem is after about 10 minutes of use, the phone drops all connectivity. THe first 10 minutes everything works, 3G, Edge, WiFi send/receive calls, send/receive mms/sms all of it is great then all of a sudden it drops everything.
Im thinking its because Im not using the right firmware/baseband. So I was wondering if someone out there has a Koodoo phone unlocked and is trying to use it on the Rogers network, which baseband are you using?
Phone = Koodoo SGA unlocked and trying to use on Rogers
ROM = CM10 nims/biel.tv nightly's
Android Version = 4.1.2
Baseband = S5830XXKPP

Yes i check the APN and all is OK!when i have turned on 3g i have signal only when i turn off 3g i lost signal
Could be that your area signal isnt that great on 2G network when 3G is off.. try another modem
hello i had issues last week i lost data connection i flashed all different roms trying to fix it ,i think its sorted now i flashed XXJVU stock rom then darky 10.2 re then i flashed cm9 then darky v11 then cm10 then thinkbridge 4.2.2 working well so far if its just your signal try 10. 2 re first
the best reason why it happen because the ROM or FIRMWARE that you installed in your samsung galaxy s is not compatible some firmware and roms are only allowed in a specific country because it contains MODEM that makes your cellphone to have a signal on what country you are in OR the Samsung Galaxy S that you have is only for certain country only like my Samsung Galaxy S SC-02B which is NTTDocomo which has 2.2 froyo firmware when i upgrade it to higher firmware such like jellybean or icecream it successfully upgraded but you cant use the cellphone 100% since the signal will lost because your IMEI is fake or your IMEI is none. check your back of your samsung to check the right IMEI.
SOLUTION:
downgrade your phone back to its original firmware and rom make sure it is the original!
and you will see it will back to its default settings your signal is back so as your IMEI
I am using Hong Kong Modem and I am in the UK with Full Signal and better performance
All Modems will give a signal ..but depends on area that you are in
Flash 2.3.6. Then Root it ...this will put all files back to the way they where..
In your APN settings scroll down to the Authentication Type and make it PAP if its Default for both ..reboot phone if that helps
hi,
i upgraded my phone to 4.2 jelly bean slim rom . calling and other things were fine . but from tommorrow i am facing this problem.
in settings=>about phone=>status it's showing my network name and signal strength-64dBm 25 asu . my network is not 3g or 4g .
but my signals are white ( no signals but sim present and detectable) cant call . whenever i try it says "mobile network not available".
after this i checked my sim in other phone . it is working fine.
i put sim from some other network in my sgs but same problem
i flashed the same rom to fix it but no good
i flashed back my ics rom , no good
i did factory reset , but problem is still
i am using this phone for past 2 years and this problem never occoured.
PLEASE HELP ME .
there is some problem with the 4.2 rom or whatever, but you easily fix the calling part by installing another modem.
in my case I can't get the sms to get working, tried 3 modems already.. everything else is super fine.
I had a similar problem where I had no reception! Easy fix though
1. Find online your specific carrier ROM for the phone, (eg. AT&T SGS1 ROM) and flash it, firmware can be what ever (gingerbread, eclair, ICS)
2. Flash your carrier ROM, you may not pass boot screen but that's alright because the carrier ROM still embeds all carrier info.
3 Now re flash your jb ROM and enjoy
Hopefully this helped you out

See how your IMEI is now something like 00499....? The phone's generated a fake IMEI (which allows you to use the telephony functions such as data, SMS etc) because its lost the real one.
1.) Go back to a stock 2.3.6 rom using Odin. Your IMEI should be back to what it was, but check it just to make sure. However if you're able to send texts/make calls/use data again, your IMEI's been restored.
2.) Root it again.
3.) Flash in CM9 first (do the standard wipe data/cache/Dalvik). Let CM9 boot. To upgrade to Jelly Bean from Gingerbread, you need to flash in ICS (CM9) first to preserve the IMEI. Once CM9 has booted (you don't need to stay on it for too long), if you see that you're getting signal, you're all goods. But check your IMEI just in case you want to be sure it worked.
4.) Back into recovery. Wipe combo (data/cache/Dalvik) again just in case. Install Slim Bean from there.
5.) Once it boots, you should be getting signal as usual. Once again though, if you really want to make sure, check your IMEI.

Hello, I have this SGH-T879, It had the stock 4.0.4 firmware, but I flashed the SGH-T989_UVLE1_radio to unlock it via service menu, but now I don't have signal, right now i'm running CM10.1 and tried to flash multiple modems but still don't get GSM signal, i have Tmo_SGH-T879-UVLG3_radio installed right now but still it's not working, it says NO SERVICE. - TELCEL (my carrier), even it shows me the Voicemail icon, but what I need to do? I'm searching everywhere the stock odin file for going back completely to stock, but all the links are expired, help me please. And I don't know if KIES is usefull but I don't know if its possible to use it in this case.
Long time lurker, first time poster.
Long story short, a friend gave me an I9305, however, I can't connect to a supported 3G network.
He had toyed around with the device (rooted, installed CM11), then reverted unrooted and reverted to stock firmware. When I got the device, I rooted it with Framaroot, flashed CWM 6.0.4.5, then flashed CM11 and Boeffla kernel. My SIM card was quite old and my carrier told that it doesn't support 3G, so I filed up for a new one. Ok, I got it, however..I'm yet again stuck on EDGE!!!
Tried reflashing CM11, CWM, flashed almost every radio baseband modem from here http://forum.xda-developers.com/showthread.php?t=2010116 to no avail. My IMEI is intact, as well as my Serial Number.
Yes, I read all threads, I tried going to Settings>Wireless&networks> More > Mobile Netwroks >Preffered Network type and checked all options. When I select 3G only, the icon goes to "H", but i can't access the web. After 10-20 seconds, the H icon dissappears and I'm forced to reboot the phone to regain my EDGE data.
At the moment, I'm running the latest Omni ROM nightly. My operator supports all 3G and LTE bands, and I got the correct APNs.
Should I flash a stock ROM and check if this does the job?
I'll greatly appreciate any help, because I'm stuck.

I can't check my csc code - whenever i type a code in the dialer I get "connection timed out or invalid mmi code". The only ones that work are *#06# and *#*#4636#*#*...
Ok, so I'm running a stock 4.3 rom and STILL have no 3G....tried everything.
Anyone, help?
Maybe if you can try to downgrade to a firmware 4.1.2 via Mobile Odin and then try and access the service mode menu. From there you may be able to enable the 3G/LTE DRX (Radio) which seems to remain a permanent change in the phone once you upgrade again to 4.3.
