[Q] No Service - Insert SIM card. Does not recognize SIM after Root with custom ROM

Rooted my AT&T Samsung Galaxy Note ii (SGH-I317)
Installed custom ROM and now get no service.
Upon checking Settings -> Mobile Network
It says: INSERT SIM card Insert SIM card to access network services
About Devices has all the correct information except:
Baseband version says: UNKNOWN
How do I fix this?
Did my SIM card somehow and need to get a new SIM and call AT&T to reactivate another SIM?
My guess is that I would need stock ROM image to fix this but cannot find it.
I did find Stock Rooted I317UCALJ2 (http://forum.xda-developers.com/showthread.php?t=1986556)
image but still no Service.
Any help would be appreciated as my phone is a BRICK now and useless.
thanks

i have the exact same problem and can't seem to find an answer...
restore stock rom and still nothing...

did you flash a ROM & Radio for the international Note II (N7100 or N7105)? check your phone for an IMEI number; if it's not there, then you'll have to fix that first. you aren't the first to have this problem and i've read other posts where users were able to correct the problem.

I like how no one responded for 2 months.
Worst case scenario flash stock and triangle away to 0 flash counter amd take it back. Lol. Say it stopped working.

Your comment makes a lot of sense... I'm running root on stock and didn't have a problem. I've recently installed CMW thru Odin which I'm pretty sure I did right but then...I installed a kernel to be able to overclock... could the kernel have mess up my radio? I'm not able to pull up my imei... Can you point me to the right directions in order to restore my stock Rogers kernel?

I have been here. Installed the CrashRom which was probably not meant for 1317s. Though I loved the ROM, my model number was displayed as 7100, IMEI was null and mobile network would display insert sim message.
If you watched the installation of the rom.. you would have noticed that at the end it rewrites your modem/radio files. Thankfully even after a wipe, the all important NV folder was there.
I was able to find the original AT&T rom at stockroms and also the original modem files for the 1317. I did a full wipe and installed this rom back..and thankfully the radio was back online. Didn't have to flash the modem. Now with a working phone, I wanna read well before I flash my rom again.
Hope this helps. Though I am a newbie.. If you need any further information.. feel free to send me a message.

If you look in the development section in the All in One forum link, there is a link to the stock rogers ROM and radio.
I don't know if you have done this but it hasn't been mentioned in the post so I thought I would mention it.

I had the same happen to me. The radio just quit. I had a circle with a slash through it. I Odin flashed the stock tar and no luck in fact it got worse and I had to get phone replaced. I have a ton of flashing experience and this was a first for me. I think like someone mentioned above it was a mix match ROM with some pieces from the international version although it was posted as an AT&T ROM. I still have to send it back but after seeing that someone above fixed theirs I am sending a PM

Yeah that's exactly what happened to me, lol, installed the CrashRom. But thanks to this failure of epic proportions, I've learnt so much and I've succeeded in restoring my Rogers modem files
Now I got my nandroid backup, and if I mess up again, I got my Rogers stock ROM, radios, and kernel with me at all times

I know from past experience using ODIN for the Droid Charge, we had to pull the SIM before flashing. People were getting their SIMs fried sometimes. The remedy was to remove until the flash was complete. Avoid touching the contacts though.

I wanted to bump this as I am having the same issue. I tried using Odin to reinstate the stock rom and radio and still nothing.

So this happened to me and after I unrooted and factory reset I had no luck, called Att and got a new one. But I don't know why it stopped reading my sim, it. Worked in my iPhone 5. Strange

can u give any links to these forums, yes i install n7100 rom on my i317 and yes i don't have a imei.

Well my friend ...I've got to tell you up front ...that the likelihood of getting your device repaired on your own is remote at best...
You have damaged the device partitions ...and likely do not have a usable backup of the EFS folder..
The EFS contains the IMEI number used for restoration purposes...
I'm not going to tell you that a repair cannot be done..as a select few users were able to fix a bricked device...but I will suggest your best solution ...IMHO
Contact the good folks at :
mobiletechvideos.com
And let them know what you did..
They offer a complete restoration service to repair your device correctly ...and can likely do the job in about a week...
They are located in Texas, USA I believe ...and they have an excellent reputation for quality service...
Your choice of course...but if I were in your situation...I'd send the device to them in a second...
Time is money...at least for me...and although I could probably fix it...I don't have a RIFF BOX...or a JTAG ...
Others will post up with links to help you...and after you have a chance to look them over ...you can decide..
Very sorry for the damaged phone....g

I have a similar problem. I installed Superandroid 4.3 on a telus/koodo s2 t989D. I had to update the radio to flash the rom. I used CWM for that.
Now the info I have on the phone is
model sgh t989

The phone is not reading my SIM at all. It shows my carrier but no signal strength at all. I have read the above post. My IMIE number is still there.

Problem with modem/not registered in network

Hey guys!
The idea is that ,by mistake i flashed a s4 modem on my note2 (my wifi was not working and i thought the problem is the modem and i found another modem but i didn't pay attention to the title).
Now my note 2 says that it isn't registered in network
I tried flashing a modem but no succes. Wifi is now working( i installed another rom -allianceRom) and i tried to go to settings-mobile data-network operator(last option .don't know how to translate) and register manually in a network but that was unsuccesful again...
I mention that my phone is from Romania and the network was COSMOTE
I don't have any efs backup as well..don't know where are them. I remember i saw 3 of them in a folder when surfing trough storage but i can't find them now...
What can i do ? I need my phone

I repacked N5120 rom and installed on my i467M, rom is working fine. I have the dialer now. Only problem is , modem.bin does not support calls, whenever i try to make a call, it ends the call.
I have tried modems from some other samsung devices but those are causing boot loop.
So far i have tried Note 2, Note 2 tmobile, note 8 5120 and may be couple more. If we can find a modem that will not cause boot loop then we will have a note 8 that is a huge phone.
Can anybody suggest a modem that should work ??

This is where I ended up. I was able to modify the stock image and enable phone support. Turns out the phone app already exists. I did not try different modems.
A suggestion would be to try a sim card from a working phone. The device IMEI may be blocked. I have been busy and have not been able to test this.
I plan to get back to this soon.

True.. But I did get my model for $300 with an S4 Active. If we can get it working, it would just be for kicks. It may not have a practical purpose. Also, ATT may not allow the device to make calls no matter what we do.
For those looking for an ATT compatible unlocked model use this link.

Not sure myself. If we get it working it may be worth trying?

Have you tried reading up on the old P1000 Tab 7 forum?
That was the first tablet to make calls and could have some tips on how they figured it out.
It was more than just flashing a stock euro rom and modem if I remember correctly.

Hey guys, I have an unlocked I467, using my local sim. connected on my local network now...Just texting works though.
downloaded a 3rd party sms...I'm just saying that as long as your IMEI is not bad, it don't necessarily mean that
you cannot use it on other network if it'sunlocked, in case you were able to get the phone app working...
....Just a thought.

yes reflashing modem will fix it ( some times loosing imei can be related for the dialer with new modem they wont be compation ) so dialer so need to be changed. but the pers who are having boot loops cause of the modem and they didnt loose the imei, or even for whom is saying company maybe have blocked this imei from making call. they can just flash the efs of other note phones supporting calls. and all shld be ok.

[Q] Samsung Note 2 emergency calls only - please help

Okay guys, youre my last hope, its now 8am and ive been at ths since 6pm yesterday evening and im on the verge of tears!
Got a preowned Galaxy Note 2 yesterday afternoon, the owner showed me it working on a 3 sim so I know its working and I know the IMEI isnt blacklisted.
Got it home, put my 3 sim in, all working fine. Then I realised it was running a slightly older version of android than my old phone. Couldnt update over wifi, kies wouldnt let me update, checked the phone status and it said 'modified'.
So me being me, impatient and all that, I used Odin to update it to androinf 4.1.2. Ever since then, its been showing emergency calls only.
Here's a quick rundown of what I've tried;
- rooting the phone
- put 4 different roms on it
- put the stock firmware on
- put a rom on for the modem (which had switced to an invalid IMEI number somewhere along the line but is now fixed)
- factory reset
- toggle plane mode
- sim in, sim out, sim in, sim out...
- checked my sim in my old phone - working perfectly
I cant think of whay else ive done. Ive been at this for 14 hours straight now.
Basicslly, I know the phone was fine when I got it. Ive done something to it, and I cant for the life of me figure out what ive done.
The only thing I can think is its the files ive read so much about, EFS files or something like that... I didnt take a back up of them before my impatient attempt at upgrading to android 4.1.2...
Can someone please help me? I think ive read every post on this site about this issue and nothing mentioned seems to work for me! Im literally on the brink of tears cuz I just want to play with my gorgeous Note 2!
Thank you so much in advance for any help, hints, tips or advice.
Thank you.

They are not hacking my friend...
Have you verified that your IMEI and EFS folder are normal ?
And have you verified your APN settings for your carrier ??
You mention flashing several roms on the device...
The items I listed will help you determine if any damage has been done....and also help you get service again...
All are knowledge you must have to prevent bad things from happening...
If your carrier did an official update to 4.3 while the device was rooted and running custom firmware....then you absolutely need to start fresh to clean the device up again...
Are you getting Knox errors or force close issues ??
Basically....in order to help you we need a detailed status of the device...
Software version....kernel version ....and baseband.....
The information is in settings/about phone/....and will tell us how best to proceed....g

I'm confused. The first post you were on Skynote 4.3.
Now you are 4.3 stock rooted ???

I'm still confused.....
Reading your first post, ATT flashed your phone to the latest update??? And changed the SIM? And that didn't work?
Why did you leave the store when your phone didn't work?

They told me they can't do nothing about it and the warranty was voided too.

Interesting. I'm asking questions I guess really dont matter.
But why was warranty voided, or was it expired?
Again more confusion.... Just wondering why they changed sim, flashed update, then told you to hit the street with a broke **** phone.
I can understand not replacing it, warranty whatever.
I took an Atrix2 phone into the shop, no working data. I had called tech support, they had OTA refreshed it, didnt work. Set me up with tier 2 tech support, more resets. Nothing.
Went into store, got another sim. Turns out it was simple. I had turned off the data plan awhile back until I was ready to give it to my daughter.
Got online, picked a plan. Data lite off.
Point is they worked with me to find the problem on a phone that was 2-3 years old.
You probably should follow me how to in this section and flash the stock 4.1.1 and go from there.

Well you have nothing to lose at this point then.
I doubt you will find a canned click next solution.
You will probably have to go the "hacking" route.
Good Luck.
