[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

t989D problem
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
android version 4.3
baseband t989uvmc6 .
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.
Any help

No Service after flashing latest Jedi X

I have a t889 and a original sim card which was cut to microsim form. I had no trouble getting service. I rooted successfully and still had service. At this point I performed nandroid backup and efs backup and attempted to flash jedi x following all steps provided in the thread (wipe data, cache, format system, wipe dalvik, fix permissions). As soon as I did this I lost service...it has bars but no voice calls and no 4g. My IMEI still shows however. I ve tried everything from stock factory restore through ODIN to restoring efs, flashing stock radios/kernels restoring nandroid still cant get service, defintely need some step by step advice on how to get back my service. I feel like I followed all the appropriate steps to flash the room.

How does the imei dissappear and how the heck do we avoid that?! Thanks so much.

I was in same bout as you. I used my insurances claim and got a new note 2.
Sent from my SGH-T889 using xda app-developers app

So did all of you flashed this rom and this happened to you?? Im confused.

I've been flashing phones since
<------
2007 and this note 2 I am terrified of flashing. every other day is a new thread just like this. Nobody knows why, nobody has a defacto solution. The only remotely close info I've read that works is to unroot and flash to stock. Even that is a gamble. If that does not work, consider it a loss. Sell it on eBay as a bad IMEI phone

Hey guys just fyi to let you know what I found with this issue. Just giving my input.
Well it looks like my imei is populating but my note 2 no longer gets service. Im probably going to warranty it so I can get service again I spent all of my weekend trying to fix. I think this issue may be related to something within the modem or radio being flash incorrectly and somehow corrupting the efs files. I searched forums about efs corruption and I think maybe it has something to do with a nv_data file missing? Not sure if that applies for sgn2 but I couldnt find or maybe I dont know WHERE to find it in root explorer. Maybe if we compare a working sgn2's efs file with a NON WORKING sgn2's efs file maybe that would help? I followed the steps in the t889 root guide step by step... and then as soon as I flashed Jedi 9 through cwm recovery BAAM...service was gone.
I tried reflashing, I tried reflashing stock modem\kernel and reverting back to stock via odin but no go.I did notice it was able to connect to tmobile for one to two sec because it would actually sync the time and date after turning on for the first time. But never again after that. My Imei and bars are showing ..but when I make a call it says "not registered on network" and no 4g either. I think this may be because the rom had included a different radio not sure which one defintely wasnt the canada ver. Flashing this rom somehow made my phone stop receiving service...Does restoring efs backup a guaranteed fix the lost imei/ service issues? Can flashing using earlier version of odin cause an issue? I used 1.84. Everything passed successfully however. Just throwing ideas to help. I definitely want to try to avoid the issue when get my note 2 back from repair.

I know that efs and modems are fixable but I believe there is additional steps needed to fix the imei... not sure if there has been a solution on that but im looking everywhere... found that you can pull your batter, write down your imei, us nv tool to create a nv file and flash it to the phone but not sure how it works with GNII... I personally havent had any issues so am not going to test with my device but for those with no service you could atleast try and report back for others... go to galaxynote2root website and find the videos on flashing tmo to att and vice versa, youll find the programs needed, drivers, etc and basic instructions to what im suggesting

Does the phone even register to the network? Have you perhaps tried a different sim? I know you will be limited as to the carrier but try a friends sim just to be sure. I'm sure you could even take the phone to the dealer and they will test a different sim in the phone.
Has your IMEI possibly changed somehow, maybe it is acting like conflicting IP addresses on a network.
In Kies there is an emergency firmware recovery, perhaps that could help. I know I am probably not much help but 1 cent worth of help is better then no cents.

+1. As a newbie I was able to flash anything on my moto defy / ME525 without worrying a bit of bricking it, but I could only eagerly wait OTA update on my T889V.

I've actually been experience serverely degraded service since I flashed MyRom Revolution v2 last month, and not matter what I flash since service is questionable. I'm on the latest Jedi -XX from the 6th, and my 4g/3g service is 90% not there anymore, and i will flip to edge sometime for roaming on AT&T even or jsut be without service altogether... I've flashed the lastest modem from the Jan 26th, no help. New rom, ... no help. I'm ready to have my phone exchanged as well. Any ideas ?

Some people were having issues with the January 26th update flash back to ll4 and see if that doesnt improce things... also seen a thread refering to band 2 issues with one response refering to ATT towers... did you by chance ever download a ported ATT rom with a modem part of the install by chance?

Hi,
Just explaining. EFS is kind of a folder that contains the IMEI number and other MAC addresses of WIFI or Bluetooth. What happened when you rooted and flashed a ROM is that the EFS folder has been modified. There are many reasons why this happens. So, changing a new SIM won't work. You would have to fill the IMEI number and the other MAC addresses to make phones calls and etc.,
Regarding whether to leave the phone with root or not, It depends on you whether you can make up a convincing story to avoid charges for re-instating the IMEI number back by Samsung.
You can change it to Stock if you want to, but Verizon can easily find out that you had rooted it since IMEI number won't be wiped by any other way..

This is what happens when you don't even read the thread, but just download the file and keep pressing next. I guess you learned that you should READ before you flash. You might wanna try flashing the original firmware from Sammobile. But I guess you're in a pretty big problem now.

Hi,
The first mistake you have done is that your phone model is not N7100. It is different for Verizon. That's the reason your IMEI number got screwed up when you flashed a rom of N7100.
The Fail in Odin is not a big deal as it might have been because there could have been two usb connections made or as you said changing usb ports.
Please verify whether the ROM supports your Verizon model before flashing.
Also, There will be still a counter and status that would indicate that you've rooted before If you want to reset these counters then search in the forum and you'll be able to find out.

You make out like resetting the counters is easy or something. It isn't and it's reasonable price for the app.
I suggest you go to the Verizon Note II forum next time unless you want to break your phone again.

I had similar problem. May be you haven't deleted it. The #4 comment is kinda right. By mistake I wiped my internal storage without backup or without writing down the baseband and build numbers. I had to flash numerous stock roms until I was able to make phone calls and receive msgs. Also on stock roms that were not for my phone the imei # was different from the one on the box, starting with 0049 or something.

Flash stock and the might sort the baseband out
If that doesnt work just send it in after unrooting. I had a similiar problem but I acted dumb and said it just happened and they took it in and repaired within 12 days.

EFS backup
The moral is to backup the efs folder ASAP, at least before you try anything 'drastic' to your phone

lost imei
I also lost my imei the first time i flashed custom rom on my note 2. but i simply flash older modem and its working fine since then.. ohh and i als made efs backup using terminal emulator..

[Q] HELP, Note 2 ATT can not connect to network.

i have Note 2 ATT, i am having network connection problem. i can't connect to my ATT network connection . i get circle with line in middle.
i took my phone to ATT store and they tried changing the Sim card and even updating my phone to the latest update, but it did not work.
i tried downgrading my phone to stock Rom when i downgrade the phone. it seems to work fine for five minutes or so i even made a call after one call it started showing same circle with line in middle. i tried flashing all different Rom, i even tried re flashing MJ4 modem. nothing seems to work.
i research to find a solution but i didn't find any solution to this problem. right now i am on Sky Note Air 4.3.
please help me i appreciate for any help.

i have Note 2 ATT, i am having network connection problem. i can't connect to my ATT network connection . i get circle with line in middle.
i took my phone to ATT store and they tried changing the Sim card and even updating my phone to the latest update, but it did not work.
i tried downgrading my phone to stock Rom when i downgrade the phone. it seems to work fine for five minutes or so i even made a call after one call it started showing same circle with line in middle. i tried flashing all different Rom, i even tried re flashing MJ4 modem. nothing seems to work.
i research to find a solution but i didn't find any solution to this problem. right now i am on Sky Note Air 4.3.
please help me i appreciate for any help.

Try flashing 4.3 rom from scratch (wiping dalvik cache, data/factory reset and cache partition) ? May be this will help fixing problem
If you want you can try Stock Rom - http://forum.xda-developers.com/showthread.php?t=2589891

Also make sure you have an APN set. @Bajanman has compiled a list of several AT&T APNs in his thread here: http://forum.xda-developers.com/showthread.php?t=2172110

I had a similar issue and this post helped me.

Also check your SELinux setting.
Once I set mine to permissive all was well.

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 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.

[Q] IMEI says 0 on 4.4.1

Hey guys, I think I screwed up. I think that I lost my IMEI through flashing it and I didn't make a back up. It says 0 and only very few of the *# codes work, the *#7285# and #22745927 codes do absolutely nothing and the only one that I know of that works is *#*#4636#*#* which doesn't help me at all. Most programs that I use don't detect the phone correctly or my phones just downright wrecked. Example is DFS says CPS N/A in every section and Samsung MEID Repair says "Unhandled exception has occurred in your application" when I try to connect it to my phone.
I'm running CM11 4.4.1 and I had the problem when I was running a 4.3 ROM. Also I have data and I can make calls. Its just that I cant send MMS and I drop to edge over time and stay on edge until I restart.
Any help would be greatly appreciated. Everyone I call is saying it'll cost $65 - $75 IF they can even fix it.

Try to use nv writer to inject the imei.

Note that if you reinject IMEI, it might screw up your network

I wish I could, When I try to use it, it says "Failed.. phone does not answer". Keep in mind that *#7284# doesnt do anything at all.

Did you know that you need to be completely stock in order to use the code?

I did not. That helps a LOT. Thank you so much. I havent tried going back yet, I'm gonna be more cautious about what i do now. Can I go back to stock from CM11 4.4.1 without screwing anything up? I keep seeing that you cant downgrade. Is that the case or is it just the case with official android roms?
Thank you so much, I feel like with your help I may be able to fix this. What im thinking that I have to do (I'll wait for your opinion) is that I should flash to stock, use the nv reader/writer, then ill be able to reroot it? When you say that it could screw up the network, what exactly do you mean?

I'm not sure what bootloader are you using
but IF your phone is fully unlocked, it doesn't matter, just flash 4.3 Stock and you're good to go
check out this post if you need help getting back to stock http://forum.xda-developers.com/showthread.php?t=2658486
the reason why you see people keep saying you can't "Downgrade" is mostly due to the bootloader you have, and it only apply to if and only if you're downgrading from MJB bootloader to a older version of Touchwiz (ie. Touchwiz 4.3 which will obviously come with MJB, thus you can't downgrade to 4.2 or 4.1 versions of touchwiz), not AOSP. if you're on AOSP in which CM is one, yes you can go from one AOSP to another, but no one does it because most of the time newer > older =D

Cool. Im using CWM 6.0.4.3. Youre saying flash back to stock, then use the codes and the NV reader/writer? Also, when using the ZIP. am I using this through CWM "install zip"?

Yes.
but again you might want to update it to latest version since according to this http://forum.xda-developers.com/showthread.php?t=2658486, he mentioned version 6.0.4.5 and 6.0.4.7 though he didn't say if it's necessary to be but to be safe, you should so that you won't run into any issues.
though again, let me warn you, Reinjecting your IMEI, will work, BUT at the same time, it might screw up with your broadband
I experienced it once with one of my S3 and it stuck on either E or G network.. and I had to fix it by copy my efs folder to that phone in order to fix(and unless you have a good friend with S3 phone with same model, or own more than 1 S3, you won't be able to do it since nobody want to share, apply to me as well)

So now that Ive restored to stock, I have a transparent window with yellow text in it. it reads a bunch of info on the phone. It also said that it was in factory mode?

So despite being stuck in factory mode I was able to write the NV and luckily I dont have any new network problems as far as I know. However my IMEI now says / 00 and in the phone info it says "unknown"

So this is my progress so far. I have made connection with the NV items reader and I have saved the NV file. when i rewrote it i noticed that my imei is / 00 and it says unknown in the phone info. I have my imei and my converted imei and i was going to insert it into line 00550 but that line says "00550 (0x0226) - Inactive item". Factory mode is still on, I have edited the text files for both factory mode and keystr from ON to OFF and back again rebooting my phone each time and getting no result.
So im stuck in factory mode with / 00 imei. I can however make connection with programs now, I feel like im moving forward.
I feel like it may be worth noting that ive never ever seen a nv_data.bin in my phone....

make sure that you take your SIM out before injecting imei... then try again
and nv_data.bin is in your efs folder which you can only see it if you have some sort of root explorer

Still nothing, im getting the same result. This Nv data bin file is not in there. i mean, unless i dont know where to look, but ive checked the whole EFS folder and its not in there...
