*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).

I flashed Sonic 4.1.1 right after I got this phone (in November), and it worked awesome until last week when I tried to flash 4.2 on it.. I lost 4g and now it mostly stays on Edge.. Any ideas...? I did all the fixes I could find on XDA, I flashed back to factory,, Factory reset it, and everything I could think of... I'm stumped and my phone is slow..
Look at this thread. It may help. You will need to be on a Tw ROM.

Choose all lte first then automatic. Since your stuck on edge select all wcdma too. Just select automatic as the last thing you do before exiting that menu.
Got It!
Great directions guys! it's working now.. Whew, I missed my 4g...
Well, you all helped me figure out how to get 4g, Now how do I get it to stay connected.. It will only stay connected for a few mins now, then it goes to E.. I can get 4 g at will now, but it won't stay connected...

Thanks for asking... Yes I did lose the IMEI, and had to restore it.. I also went to radio shack and got a new sim card. I have factory flashed and reset it and did all the steps on the link above..
Hello,
i am back again with a new problem!
All the previous problems that was mentioned in this forum is GONE. i was a happy owner. Until i got this problem.
so i wanted to try new Modem, just so i can increase my Signal, and right now, my data plan is keep going on and off, and most the time i can't get it connected it.
i did the wipe date /factory reset from the ROM manager, and wipe cache and dalvik. and yet the problem is not solved.
right now, am running cm-10.1-20130304-EXPERIMENTAL
and the Modem am currently running which sometimes works ( I747MVLDLK4 ) am with Rogers, Canada, Edmonton, AB
If anyone helped me out with this, your next coffee is on me! for real!
anyone?
When I have Wifi or Signal/Data issues, I just Odin back to stock and then re-root & flash ROM again. Works every time.

Yes! i think i did a mistake. While i restored to the stock rom, The baseband that i was using it was I747MVLDLK4 and not the STOCK modem. So maybe that is why its not getting connected? am trying to apply the stock modem into the the stock rom, but its giving me Fail error.
am just scratching my head right now to be quite honest and this close to throw my cellphone outside of the balcony.

i managed to make my modem into the stock version. However am just getting "E" in my data connection. Reminder am still in STOCK ROM and stock modem now. is that a good sign that i slighty getting everything back??
should i just install the CM 10.1 now and see the results or what you guys recommend?
annnnnnnnnd my " E" is gone.. Beautiful
do you guys think it might be a actual physical sim card issue?
UPDATE: i restored my phone into the stock rom by Odin3 and now i just re flashed the Cm 10.1 again. sadly i still have no connection and my income and outcome for calling and texts is also not working.
please help!
Try flashing Task's AOKP and see if you have the same issue. Additionally, try deleting the current APNs (access point names) and manually enter the APN settings for your carrier. Could also just be a faulty SIM card as you mentioned.

Thanks guys for the feedback, but i have managed to fix the problem, this post was before i know that i lost my IMEI...
All good now, everything has be resolved.
cheers,
Hello,
I'm having a lot of difficulty getting my Note II (SGH T889V) in working order . I'll try to explain the situation in an organized way. Thank you for your time and kind help!
Background
I have a Note 2 from Wind Mobile in Canada - SGH T889V. I got it 2.5 months ago. It was rooted, was running TWRP and I only loaded one ROM, flashed once, on it - 4.1.2 modified touchwiz ROM. Never once had an issue. The ROM was super stable and in great working order.
I got it unlocked about 2 weeks ago because I was visiting the states. When I got to the states, I put in a T-Mobile sim card which was working great for a few days. One afternoon during my vacation I was having slow data issues, so I thought to change the modem/radio from a Wind Mobile radio to a T-Mobile radio. That gave me 4G data speeds but killed my calls. So I tried to go back to the Wind Radio and that had my phone complaining that there was no SIM card. I went back to the T-Mobile radio and I got calling back but only 2G data.
My IMEI was corrupted - it showed up as zero. I left the T-Mobile radio on the phone when I got back. My home network wouldn't recognize me and thought I was still roaming.
Attempted Fixes
Tried a basic factory reset. Tried a different ROM. Tried wiping all internal data.
I got home and tried to flash to stock ROMs found on XDA for Wind Mobile phones. That didn't solve the issue. The IMEI remained null. The phone would reboot automatically every few minutes unless I turned Airplane Mode on. I figure the phone was looking for a signal and couldn't because of the IMEI problem.
So I looked around on the net and found a link about injecting the IMEI back using QPST (http://forum.xda-developers.com/showthread.php?t=1206275) but I couldn't get the program to detect my phone so I gave up and thought I could just get my binary count to 0 and stock and I'll just take it back for warranty.
I tried Triangle Away but I couldn't get the counter to go to 0 even with stock ROM and recovery. So I thought I would take it to a cell repair shop locally. I took it there and all they did was cause an issue on the phone to make it appear that KIES firmware upgrade failed so that it would be repaired under warranty. You would see a emergency firmware upgrade error the minute you turned the phone on. However, download mode still showed the custom binary count at 1, they didn't get it down to 0.
I spoke with my carrier and with Samsung anonymously, they said the counter would be an issue if I sent it in.
I came back home and tried doing the following, with the hopes of trying Triangle Away again:
1. Installed TWRP via ODIN and ran the restore on the backup I created in TWRP when I first got the phone. I restored everything including EFS. Phone boots to the stock samsung rom but it would restart automatically every few minutes. Even with Airplane mode on, it would still reboot on it's own.
The KIES error message doesn't appear anymore.
2. Went back to ODIN. It was getting stuck on SYSTEM in ODIN version 3.07 when flashing a stock rom. So I switched the USB port on my computer and used ODIN 3.04 then the flashes went through properly with no hang ups.
So I tried to flash a prerooted (http://forum.xda-developers.com/showthread.php?t=1975560&highlight=wind) stock ROM
and
also a basic stock ROM (http://forum.xda-developers.com/showthread.php?t=2061031), along with a stock recovery
Both just get stuck in a bootloop. I tried going to the stock recovery and wiping data, cache, factory reset several times. No luck - still boot loops. Wont go into the ROM.
I did not try "Re-partition" in ODIN. I'm not sure if that'll hard brick the device but maybe that way I can repair all of the partitions? - http://forum.xda-developers.com/showthread.php?t=860432&page=2
__________
Im hoping to get back into a prerooted ROM or stock ROM to try this Triangle Away Method - http://forum.xda-developers.com/showthread.php?t=2272966 to get the custom binary down to zero.
I tried to use the Triangle Away ODIN method but it doesnt go through in ODIN, it just gets stuck.
If I can get into the ROM without it boot looping or rebooting automatically- I think I can fix my IMEI like this person did - http://forum.xda-developers.com/showthread.php?t=2145967
Outcomes Im hoping for
To stop the bootlooping/ automatic reboots, then
1. To get the custom Binary count to 0 so I can send it back in for warranty to Samsung or my carrier, Wind Mobile. The binary says Samsung Official. - http://forum.xda-developers.com/showthread.php?t=2068156
or
2. To get the phone to working order so I can try this persons method - http://forum.xda-developers.com/showthread.php?t=2145967
The phone is still responding and it's still working with ODIN. It makes me think the issue is software or partition related and not hardware related per se. If it is hardware, I just want to get this phone back to Samsung but I need to unroot/clear the binary counter.
The phone has never been dropped or damaged physically. I've really babied the phone. This is my third Samsung Galaxy phone (I've had a Vibrant and S2x before this one.)
This has really ruined my week. I need my phone for work. I greatly appreciate any kind help or guidance. I know the collective genius here at XDA will be able to find a solution.
Thank you so much!
If you have flashed the tmobile modem you will now have to keep the tmobile one in order to get your phone to boot. Flashing a t889v modem will cause loops. Dont know of any way to get back to t889v modems.
Hey, don't worry, you aren't the first to experience this problem. Many users have reported that the T889V will bootloop with the T889V modem after flashing another modem. Many have also restored IMEI and service to their phones, so there is a solution. I don't have the specifics, but there are many threads about this problem with solutions. I have quickly searched for one and I believe it has everything you need to fix it.

Thank you all!
I got the boot loops to stop by flashing CWM recovery, then flashing a TMobile Radio.
From there, I followed the QPST instructions of installing a QCN file on the phone to reenable the AWS spectrum. Then I used the IMEI creator and NV Writer programs and I was back.
Data seems alright, getting alright speeds on Wind right now. I just found my bluetooth a little hard to hear in the car this morning.
So with this process, I should stick with a Tmobile radio from now on right? If I flash a Wind/ T889V modem it'll boot loop?
Have you guys noticed any signal or performance issues after restoring the phone this way? I'm wondering if it's worth the trouble to get the custom binary counter to clear and return this phone for warranty. Seems to be working for the most part so far.
Thank you so much again! I thought I was going to have to pay $100 to get it JTAGed.
Glad to here your back and running.
I have a t889v using it on telus, and since I am stuck on tmobile modem I get lower phone signal but never loose signal. On a plus I now get lte speeds.
First day back it seems good for the most part.
Only issue I had was Bluetooth in my car would cut out at a high rate of speed (when I was on the highway). It worked really well while I was on local roads but once I hit the highway I couldn't hear the other side at all pretty much. I had to put them on speaker to hear them. They could hear me really well, better than before when I was driving on local roads.
Never occurred in the past. Could it be a radio issue? Signal seemed okay and I was able to continue the conversation over the phone speaker on the highway.

I noticed I have serious data issues when the network goes into HSPA+ mode. I get really good data for a minute then it'll cut out totally for like an hour. I tried rebooting, tried battery pulling. It seems the T-Mobile radio doesn't interface well with Wind's HSPA+ . I had full bars but the internet wouldn't load. It was pretty non-functional for most of the day.
It works decently when it's not on HSPA+
Tried switching to a Wind modem, went into boot loops. Went back to T-Mobile radio. Should I try a different T-Mobile radio?
how to fix your T889v if you accidentally overwrite the radio
If you get stuck with no IMEI, in my case, flashed omnirom 4.4.1 t0ltetmo, which uses Tmobile radio... it killed the Wind Mobile radio... restoring form nandroid did not help.
solution:
flash omnirom t0lte (not t0ltetmo) and your problems are gone!

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.

I've tried all sorts of roms, AOSP and Sense, they all stay connected to 4g for a few minutes at most after a reboot and then go back to 3g.
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.
