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.

What recovery
Sent from my SGH-T889

I flashed CWM through ODIN cwm6-recovery-n7100-121014.tar

Any help would be appreciated is it because jedi has a built in modem? Just trying to figure it out

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

I had this issue with a GS3. Had to do a warranty exchange. Ever since then I don't flash radios because that is when this can happen.

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?

Nailed it!!!!!!!!! My 4g is back again

Last week, I did the most stupid thing on my note 2 (SGH-t889). I saw a rom that i liked for the n7100 and flashed on my 889v. Of course, rom works fine but no DATA OR VOICE :crying:crying:
So I flashed my phone with my previous rom and I had data again. All of a sudden, after installing all my apps, I lost the connection. My phone went completely crazy
i saw unknown baseband on settings / phone status; phone rebooted itself. I tried to flash a stock rom, or even flash the 889v modem on any rom and no luck; i was on a constant boot loop
I had to flash another modem from T-Mobile to get out of boot looping (MODEM: T889UVALL4_Modem-Jan_16_13-teshxx) but i couldn't get on any network even if I my phone could detect them (I'm on Videotron).
I've searched xda and other sitEs for solution on how to fix an almost empty esf folder. On a tmo modem my emei was 0 0 and on videotron modem it was null.
SOLUTION
My efs folder was almost empty; no nv_data.bin and those other files.
I went across this site
http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-enable-t-mobile-3g4g-aws-bands-on-att-galaxy-note-2-sgh-i317/
It's a tutorial on how to enable aws on the AT&T note 2. It had just what i needed: a qcn file. Ive follwed the directions on the site; flashed the qcn file with the QPST software and rebooted the phone. My emei was a bunch of 0. No signal still but the battle wasn't loss.

my 4g is back and my gps is working flawwless
Now, just to let you know, I'm not a developer and i take no credit for this. Even if this thread get approved or deleted, I just wanted to help other members like me who are stuck on the same situation (especially 889v owners). At the end.... MY PHONE IS BACK !!!!!!!!!!!!!!!!!!!!!!!

Wow. I followed your steps to the letter and it worked, thank you so much!!
Have you flashed back to a VTR modem or would that mess everything up? Thanks again for your help.

From past experience flashing the videotron modem would bring me back to boot loop, wouldnt lose imei or signal but would start then after 30secs reboot.. Im stuck with tmo modem. Works fine but signal seems a little weaker.

i have canadian note2 t889v that i got from craigs the other day. everything seemed fine, didnt have sim to try for mobilicity that im on (aws band), he said he used it with rogers fine
I put the sim card, went to search networks but my provider was not listed there. So I rooted the phone , loaded twrp, flashed prerooted factory rom for t889v ( from mrrobins) , no network, than i flashed original factory rom, still no luck, than i flashed t889v modem and still the same.
My imei is present, and matches one on back of the phone. My efs folder is there and is populated (dont know if anything is missing from there)
I dont have backup of efs or imei. What are the chances it is corrupted ? Does anyone have any suggestion, and should i try this method to try to fix it ?

You may have to put your apn settings manually for your carrier. I would try that to start.

Have you check the *#2263# menu to make sure it is on the correct band, also in network setting you can switch to gsm, wcdma, so on. As for imei as far as I know if it were corrupt your imei would be bad. Is it possible the phone has been blacklisted?

That code dont work in stock dialer. And mobilicity dont block imei #

[Q] [Help Needed] Service State: Out of Service GT-N7100

Hello guys, I really need help here.
I use a Samsung Galaxy Note 2 GT-N7100, it was working fine until I decided to Root it using the All-in-One Toolkit which also worked fine after Rooting. I later decided to flash a Custom ROM (CM 10.1 - Android 4.2.2) so I did a TWRP Nandroid Backup then flashed the ROM. I was disappointed by the new ROM especially the Camera Quality so i chose to go back to old ROM.
I tried Restoring the backup but it kept failing, so I flashed a stock ROM, re-Rooted the phone and tried the Restore again. When it finally worked and I got the phone running, there was a very big problem: SERVICE STATE: Out of Service & MOBILE NETWORK STATE: Disconnected. I cant make calls, Cant send SMS nor surf the Internet. I really don't know how to go around this, I tried Factory Reset but no Success.
Help Please.

Go to about phone then status post first 4 digits of imei number. I think youve corrupted your efs..

The first 4 digits of the IMEI shown is 0049
Which i have noticed are different from the IMEI shown behind the phone itself.

0049 is a generic imei which means your efs is corrupt.. did you take a efs backup like all the rooting and custom rom guides say to take once rooted.

Check your sd card for a folder Named EFS. If not you can try flashing stock rom via odin which some people have succesfully revived there phones with.

There are loads of guides on here @Xda For this problem. You can use the search feature and type note 2 lost imei and the guides will pop up.. if your not familiar with odin you can use kies but you will need to purchase triangle away. Then unroot to connect to kies..

I had erased everything from the SD card and Internal storage :crying::crying::crying:
i have also tried the Stock ROM but there is no success.
Isnt there a way maybe that I can get the efs from another phone or download a backup? Or can the phone be revived by any custom ROM out there? :crying::crying:

The only method for you then is to purchase triangle away from play store. You should be able to use wifi. Open triangle away reset flash counter. Then in super su go to full unroot. Then open kies and click tools click firmware initialisation I think it is and enter the model number and serial number of your phone. Get this from under battery. Accept the kies download and wait for reboot. Some people have had success with this but yiu defo need to purchase triangle away to reset your counters. Without reset kies will not work..
Edit: just been looking and apparently once youve installed newer roms you cant revert to anything before dmf firmware. Unless you had your efs backup..

I have tried searching for many solutions, I even downloaded some efs image an d flashed it to the phone using ODIN but as a result it got me a new problem, FACTORY MODE. though i successfully got out of that but I still have the IMEI problem. When I search all I can find is HOW TO BACKUP AND RESTORE EFS and it works only if you had a backup or the Original Shipped efs (all of which I dont have).
Another solution I found out there is to use a Z3X BOX to repair the IMEI but very hard to find out here. so the only option I have left is the one I requested in my previous post. I hope anyone out there can help me

No one is going to give you a copy of there efs.
Youve tried odin it didnt work..

I know this sounds harsh but your gonna have to pay money to get your note running again like so many other people who didn't take the time to read the guides and tutorials before getting flash happy.. I hate to say it but youve learnt the hard way..

Note 2 gt n7100 imei problem

Hello!
I'm new to this forum and this is my first post so sorry for any mistakes i may have made.
I changed rom on my galaxy note 2 gt n7100 and my imei changet to something like 04400..
i get the signal but says not registerd on network.
so i wan't to change my imei to my original, i have original imei on back of the phone, but i don't know how to do it..
please guys i need help on this one.

What rom did you flash ??
Your device is an international version of this device ...and the I-317 roms are likely not compatible..
Do you have a backup of your factory rom ?? And do you have a backup of your EFS folder ??..(contains the IMEI number )...
If no backup of your rom exists ...you will need to restore the device using Odin and a factory N-7100 rom...
Hopefully the EFS folder is still present on the device ...so when the restore occurs ...your device will see it...
If the folder is gone...you have a serious problem ...g

I don't know if it's help. But it works on my N7100...
First of all, i'm assuming that you know how to run odin. Run odin and run your note2 in download mode (volume down + menu + power). Find a stock firmware and open achive, save MODEM file. In odin, choose PHONE menu (NOT PDA) open MODEM file that you save from stock ROM archive and start the task.
It will auto reboot after flashing.....and you will get your original IMEI again
I hope it helps =)

IMEI : null , please help

hello ,
yesterday i woke up to find my note2 not working saying insert sim card
and when i tried to check imei it says null null
i never tried to install rom or root my phone , i just bought it 2 weeks ago
i've searched all the forums and found that people only get that error when they try to flash their device but i didnt .. it just suddenly happened
would you please guide me to fix it ?
my phone is galaxy note 2 N7100 and it has 4.3 jellybean

I suggest you to take your phone back. I think it is a hardware problem. You can do nothing for that. If your phone was rooted and has a backup of your original efs partition (IMEI) only than it is possible to recover your IMEI.

that phone was shipped to me from dubai and it has no warranty .. i cant do that

Oh thats bad. You must find a service who has good knowledge about Android phones. Did you checked your phone after you received it. Maybe the phone was without real IMEI. So far I know the GSM prowiders allow a couple days to use your unregistered device.

hmmm
well thats bad
you haven't tried to root and flash custom rom at least if so if u have tried it is possible you might lose imei and which is why it is advisable to make an EFS back up.it could be a hardware related problem..try taking it to the samsung service center they are the ones who can really help you.

Try this solution: use Root Explorer enter to EFS folder, delete NV_DATA.BIN and NV_DATA.BIN.MD5. Reboot your device and check imei.

If device is shipped with broken seal on box then...
It's stolen by someone & sold him online.
& I think someone(frustrated Owner) knows & banned his IMEI via complain.and that's why he got null error while no reason at all.
It's just a guess.
