I am having problems getting GSM service in the ICS roms. I currently have service with AT&T and I am unable to get a signal. I am currently running the Gingerbread MavRom and I have calling service as well at blazing fast 3G service. I did the radio reflashing in FastBoot as well as the build.prop tweaks in Mav Rom and it worked perfectly. When I did the same in ICS, I was faced with problems.
After flashing the radio, the phone booted normally, but when I went to Settings>About phone, The model was still the same and I had no baseband, it was unknown. When I hit phone status, there was no ESN, IMEI, and alot of the other spots also said unknown.
And after copying the modded build.prop file to the system folder and restarting, I could not get past the Boot Animation. I tried this in several ICS roms all with the same result...
Can anybody tell me what I'm doing wrong?

I just flashed kabaldans Cyanogenmod 7.1.4 coming from 7.1.1. Like I've done many times, changed baseband to "Venezuela - Mobilnet" in OR, updated google apps and everything.
But now my phone says "Emergency calls only", when I check the network operators option it only shows one of the three operators in my country, and the one that my phone is registered to does not show up. Ive tried reflashing the baseband 5 times but the result is the same, still can't connect to the network for calls, much less data.
EDIT: I flashed 7.1.1 and the network works just fine..
if you've tried setting Baseband, why don't you go ahead and file a bug at http :// code.google.com /p/cyanogenmod4milestone/issues (sorry, new user, can't post links...) so kabaldan/nadlabak can fix it?
I would definitely try reflashing to the newest and using openrecovery to flash the baseband onto it. I can't imagine that would have been a broken feature.
I have been fiddling with RadioComm v11.11.11 (is this the latest version?), and there are some sections that deal with the TX power and other items for the radio. Has anyone successfully tweaked the radios on these devices? I am running a XT862 with a Xt883 radio, on T-Mobile. The reception of this phone is pretty bad, and it takes it a LONG time to find signal again, once you get it into a known good reception area. Any ideas/pointers?
Did you try using CM9 for some reason I get better reception on it.

Does it do this with all roms? It sounds like something may be wrong with your phone. I have had very few issues and I live in a notoriously poor reception area for both AT&T and T-Mobile.
Also, are you running the updated build.prop? I added some signal improvements in the v2 file.
It has done it with .894, .905 and now on .906. I realize these are VZW CDMA ROMs. Not sure if something is hanging around in there. I also have not tried swapping out any of the RIL files. Should I? I've made my own build.prop (attached), renamed build.txt, for the .906 VZW build. It gets GSM and EDGE data on T-Mobile. Would you mind looking it over? If it can be tweaked, I'm all over it!
I have tried flashing CM9, and it just keeps giving me boot loop issues. I will download the latest, and try it tonight.

It should not matter since the radio is independent. Only some custom roms might have issues with GSM. Stock Verizon would be the best place to test reception issues.
Try this build.prop on your existing rom and see if it makes any difference:

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.
