I've had this Samsung S3 for almost a year now, and in the pass week, my radio has been acting funny, It dropped the IMEI, and pretty must lost all connections with my 3G network, So I ended up wipe the phone and setting it back to the default S3 ROM, after being on cyanogen mod ROM for a few months. After a bit of fiddling, I ended up finally getting my IMEI number back, and it worked fine.... till I connected to Wifi. After I connect to the Wifi, my radio stops working period. Any ideas on what could be wrong?
I'm running a Samsung SGH-1747M, which is an AT&T version, although my carrier is rogers in Canada.

*Bad english ahead*
The problem is that my phone seems to refuse to get any service at all. The signal icon just shows a big "X" and it is stuck in "Searching for service".
Phone status shows that the Signal strenght is on -79 dBm, so i guess the anthena is working just fine. But below Service Sate it just shows "Out of service".
Im using a EB13 Modem with the SyndicateROM.
In fact, the phone was working just fine with MidnightROM until i flashed the SyndicateROM over.
Already tried reverting it to Stock rom and nothin, any suggestions?
Did you try reflashing (Just) the modem through ODIN?
Let me try...
Does this one should work? (The odin one)

Did you flash your Epic to Telcel? If so, that process might be causing you some problems. After using Odin to get back to stock, install CWM3 then SRF1.0.1, then once you're stable there, try the carrier flash again.

What do you mean by "Flashing my epic to telcel" and that "Carrier flash?" is on Iusacell, since Telcel dont support CDMA.
And one last thing, what is SFR1.0.1?
EDIT:
Im reverting back to DI18 Stock rom with odin to see if i can do something.

Oh okay - the banner under your username says Telcel, so I figured they were it. I thought I'd read they support CDMA but I was mistaken.
SRF1.0.1 is SyndicateROM Frozen 1.0.1.
On the flash, let me rephrase - did you do anything special to get the Epic to work on Iusacell, or did it work there out of the box?
That's the reason then. You can't change ROMs if you're on a carrier other than Sprint, it will revert your phone back to Sprint.

Nope, the phone was working just fine out of the box. It had signal (Roaming) and all.
I even flashed like 3 roms before Syndicate and it was working just fine. Was just yesterday that i decided to try this ROM out and got the problem.

I'm not entirely sure what to tell you - there's nothing in SRF that should/will/can cause any problems of that sort. Going back to full stock via Odin didn't help?
I followed this guide: http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S/SPH-D700 to return to Stock rom, but i can't get this thing working
Im pretty much lost as well.
EDIT:
Oh god what the... I was just messing around with the phone. Turned on the Flight mode. Made a Factory reset via Privacy setting, Rebooted the phone, turned off the a Flight mode and suddenly had signal again.
I dont know what happened, since i tried the factory reset before with no luck... But well, im glad its working now. Thank you to both of you for the help anyways.
I have a similar problem as the OP, and I'm pretty sure it's ClockworkMod that's causing it.
Seems like every other time I do something in CWM, I get no service and an unknown Baseband and Hardware version in the phone's settings.
So far the only reliable way I've found of fixing it is to Odin all the way back to DI18 and start fresh.
For some reason Odining the modem or EB13 doesn't work (I still get no service).
And I must say, it's incredibly frustrating.
I guess I'll just have to get SRF flashed and never touch CWM again (because doing so almost always breaks my phone).
I'd like to be able to make Nandroid backups though, but unfortunately, doing so breaks the modem (which really doesn't make any sense).
Hi there. My device is a i747 on Virgin Mobile (Bell) in Canada. I have no service, or 1 bar of signal (can't make calls at all).
I flashed CM10 in November. Then just the other day I flashed Synergy. Then switched to Galaxy Mod. (I followed instructions for each flash, wiped everything each time etc. even when not specified in the instructions)
Today I switched to CyanogenMod 10.1, I got stuck in a boot loop. So I reflashed back to a stock root image with Odin (root66.stock_Bell_I747MVLALH1.tar). Now I have no service! I can see one signal bar. Under status it says VIRGIN.
EDIT: Now after I typed that, I reflashed another rooted stock image, I have no service at all and IMEI shows as 0.
EDIT: Since posting I have restored my IMEI, the phone seems to be registered on the network. But still no signal just like before
EDIT: March 16: I have tried flashing modems. Then I restored to the latest actual stock (non-rooted) image from my carrier. Same thing.
Please help me out, thanks

Hello.
I just travelled by train and it picked up signals, both voice and data. Possibly because i was passing close to a cell tower. But it quickly stopped working whenever the train moved too far from a cell tower.
Then back to no signal at all.
Will check APNs, but I don't think it would start working then stop if it were a configuration issue.

Ummm... do you mean CM10.2 Alpha1? Because otherwise you're sooooo far back on CM revs it's not worth it (latest stable is 10.1.2).
Either way, make sure you're at UVMC6 baseband/radio -- non-JB radios don't work on CM10+ (JB) -- and you get what your phone is experiencing; no cellular network service (WiFi should be OK).

That's bizarre... you're not even rooted anymore, I take it? Did you do a full factory wipe after going to stock ROM (it's probably redundant, but what the hell)?
There's one other possibility -- it happened on my BlackBerry a few years ago and I got a strange error (dunno if Android gives that sort of error or where) -- basically, I had a bad SIM that still worked (it just couldn't connect, but the phone saw it as a normal SIM). I replaced it, called T-Mo and gave them the new SIM number (you can do it online nowadays) and was back up and running in minutes.
Of course, try pulling out the battery, SIM, and SD card, then put everything back in and power on...

how it worked before I flashed cm10
I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?
Thanks for the help!

Any of the ROMS that have [TW] in the title should work. Full Knox only comes with flashing a tar file in ODIN, because your flashing every partition of the phone. Modified stock ROM zips do not have knox, unless otherwise noted. Make sure to do a prl and profile update when you flash to stock.

Flashed Wicked Sensations last night with the MK3 modem and I seemed to be getting LTE as soon as that booted. Updated my PRL and Profile, and then wiped. Installed AOSB again, and I seemed to be getting LTE until I rebooted. After the first reboot I seem to be stuck in 3G again.
Im currently running AOSB on 2 devices. When I first flashed them, I had the same issue until I rebooted the phone. After that I never had this issue again.

I think that's the opposite of what happened to me. My status bar said I had LTE when I first booted AOSB (this was after flashing/wiping TW). After the first reboot it connected to 3G and I haven't seen the LTE signal since.
I have updated the APNs, but I was using the same APNs for a while and had LTE on CM10.2 with them.

ohhh i had this issue but i figured it out for pacman and most roms just download nova launcher and when you do create a shortcut on nova ad click on setting an it should say apn once there u open it and youll see where it says ehprd something like that click on it and go all the way to the bottom and change where it says bearer to ehrpd and lte should work ^_^
Ok so I finally got it working, although I'm not sure what was wrong with everything in the first place. My buddy said Cyanogenmod screwed up a recent ROM, so maybe that code was in one of the ROMs I was using.
Each time I flashed back to TouchWiz (I ended up using Wicked Sensations) I could get 4G/LTE. I ran a **72786*, did a PRL & profile update. Prior to finding a working ROM, when I went back to BeanStalk/PACMAN I would lose LTE. After I found the updated BeanStalk ROM I flashed and it still had LTE! Happy days!
At this point I was able to send MMS somehow, but phone was having problems being recognized by the network. I could connect to LTE but couldn't use the data. After I updated the APNs everything started working again.

Everything else works fine, and my sim works good in other phones and stays on 4G.
Any idea what this could be or what is causing this?
Have you updated to the latest firmware? If your using kitkat roms, you need kitkat firmware. You can find the firmware in the second post of santods stock rom thread in development. Use the no boot.img one.

Yea I've flashed those also. Everything used to work fine until that roaming display issue. Never returned to normal for me, even tho roaming is gone.
Have you ever ruu'd back to stock and then done a factory reset from hboot? That is the only way to wipe out the network settings and force them to be updated. Worth a try i guess.

I'm not getting 4g at all on my phone. I came here to post a question and saw yours, so thought posting another thread would be pointless.
I've got NusenseSIX RC4.5 running and while the 4g icon comes on, there's no data transfer at all. I flashed the new firmware first, as instructed, and that seemed to go just fine according to the directions. But, when I swapped my sim card from my other One and waited a few minutes, even *228'ed, no data.
I got the phone already rooted and s-offed with TWRP 2.7.0.1. How do I get it back to stock to clear out the network settings? Or could it be a bad firmwware flash, so I'm screwed anyway?
EDIT: I redid everything, and just stuck with the Sense 5.5 mostly stock ROM. Data works now. Might've been firmware, might've been the ROM on my phone. Zero idea.
Is it possible to have a bad sim?
I just got a replacement device and I still cannot get 4G service for more than about 2 minutes before it switches to 3G

Sure, you can have a bad SIM, but I don't think that'd cause the drop in data transfer rate... lack of data all together, or other things not working, sure, but if you can actually catch a 4G link and then it drops to 3G, sounds more like the radios, the hardware, or just a bad coverage area. I'm no expert, though.
In case anyone was wondering, I ended up getting a new SIM and that has fixed my 4G issue. No idea what was wrong with the SIM, but anyway it sucked.
