[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.

No, I didnt do and efs backup :crying:
All I remember to have done was the TWRP Nandroid Backup.

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..

Sorry to tell you that I have this problem 1 week ago, I didn't back up my efs, I tried installing more than 5 official stock roms, and I couldn't retrieve my efs nor my imei number, and finally I gave up trying and sent it to samsung for repair today
Read that if it could help you by any means ...
and sorry for your mobile I really know how it feels

It should support. Did you use triangleaway and unroot through super su. If kies detects any mods such as root or custom recoveries it will not work.. I have seen loads of people have success with this method while others have had success with odin.. if both havent worked for you, then its gonna be a costly repair at service centre im afraid..

I tried it several times but it fails with the same error. I was also thinking of the Samsung Service Center Option but :crying::crying::crying: I am in Tanzania and all I can find here are Samsung Shops and am told for a service center I need to Travel to Nairobi - Kenya (Nearby country) which is actually going to cost a whole big lot.:crying::crying::crying: so Practically am stuck with the Note 2 that doesn't work.
One final request, can anyone please please please help me with a EFS Backup image (either TWRP or CWM) and the procedure to change the IMEI in the efs image so that I can change it to my original IMEI and then restore it into the phone just to breathe some life into the device. I'd really be thankful for that.

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 tried helping you through kies that didnt work. You cant restore something you never had or deleted.
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..

Service State Out of Service
I am using my note 2 N7100 for some time now.
And I just recently update to 4.1.
After the upgrade i am not able to use the messaging and phone app.
Though Network selection was set to Select Automatically, and there is a good signal, service state is still out of service.
FYI, IMEI is the same, original Serial number remains.
what can I do. the phone is out of warranty.
please help. tried different things, but nothing works.

Search for "ARIZAPatch" it will help. But it requires root access so you will have to root your phone. I used it on a Note 2 with a similar problem and now it works like a charm.

@Bajanman sorry but that guide is useless for the LTE Note 2 variants. Look for guides from the LTE Note 2 or the North American SGS3 as your main starting points to try and solve this. (My T889V LTE guide has some links to those.)
One method I'd like to hear reports about is the reboot nvrestore one, I've seen it discussed mostly on a Verizon SGS3 thread, but nothing IMHO says it wouldn't be relevant for the HSPA/LTE versions either.
Edit: The EFS and other related partitions are of a significantly different layout between the dual-core SGS3 and the LTE Note 2 or GT-I9305. adb reboot nvrestore doesn't seem to do anything on our devices.
Good luck,
Darkshado

hey i didn't find anything...i've heard that there's some custom roms that contains EFs backup that can solve my problem is this true ? if so can anybody give me a link for one of those roms ? thank you

Try to flash with odin the stock rom that you got your note 2 with. It happened to me once where i flashed something and lost my imei. I didnt backup or anything. After i flashed the stock and unrooted my phone my imei reappeared and my phone worked again. BTW it was a att note 2. I found the rom somewhere at this forum. No rom contain you Efs i think(could be wrong) but each phone has it own imei.

This basically means you have corrupted the EFS partition of your phone. This can only be fixed in two ways:
1. Like @johntheredimid mentioned, you need to restore the backup (if you took a backup) of your EFS partition before it was corrupted. The method for restore can be found here - http://forum.xda-developers.com/showthread.php?t=2420902
2. If you didn't take a backup, you need to take your phone to a service center and ask them to fix it for you. Would probably have to have your board replaced. So you should install your country's firmware and unroot properly before taking it there. Unrooting methods can be found in the general section.

Looks like this problem is widespread

N7105 factory mode

Hi guys, i seriously need help here. Please refer to attached screenshot.
I came here after flashing sokp 4.2.2 rom, and it prompted me an error saying encryption was unsuccessful. After which, i wasnt able to use my phone since then.
I tried to flash stock rom, and I end up with this. Please dont tell me to search the forums because Ive been to them countless times. I suppose this is a efs issue, because baseband and imei are unknown and I do not have a backup for it. Tried with the writing tool for imei, doesnt work as well.
Pls ask me for any info u might need/i missed out to help with this issue.

I think it's in the efs folder, you have to use a root browser and edit factory mode to off instead of on. It's been a long time since I saw factory mode so I'm not 100%

Thanks for your reply. But even if I off factory mode, will the baseband and imei be unknown?

I'm not sure but if it doesn't the 2 things that might be worth trying are, emergency firmware recovery with kies or mskips toolkit has a rescue package but I think you have to go to skipsoft.net now as the thread was closed
Sent from my GT-N7105 using Tapatalk

It's current value is "OFF"...u have to write "ON"...i know it sounds weird but that is the value. Amd if u don't have any previous back up of EFS then there's nothing u can do at home to bring it back. Same thing happened to mine and i got it repaired from a local shop for cheap...they used z3x box...the problem is my IMEI is correct and network works fine...but everytime i flash a ROM i have to take it to the shop and get the modem patched or else it doesn't connect to network. So go to Samsung service centre and get it fixed by them...they'll charge u more but their fix is permanent.

Alright, it seems like i have a backup of the efs, bt the nv_data.bin file is not included, and i read on other threads that this file is responsible for the imei and all? This backup is dated in aug2013, but it doesnt help in restoring my phone because the efs pro software doesnt see this as a backup file. Im actually looking for one of the thread that actually taught how to edit the nv_data.bin file, but no luck till date.

This thread might help

STILL NOOO HELP
Please me, i have lost my IMEI saying NULL / NULL and im getting not registered on error. I have not backed up ESF folder as well.
Struggling from last 5 days to fix it up. some how i got Modem_N7100XXDMG1 and flashed. After that i have got some fake IMEI.
Tried flashing STOCK ROM 4.4.2, but still no luck.
Read on some forum that MODEM of 4.1.2 or J.B 4.3 resolves this issue but when i try to downgrade from 4.4.2 to 4.3 via ODIN it straight away shows FAILS in RED
IM using Note N7100 K.K.4.4.2
PLEASE PLEASE PLEASE HELP ME.

If you have no backup and the stock ROM did not work, they you are pretty much out of luck. I had a backup but the IMEI didn't come back until I flashed a different modem. I used modem_XXDME4.
If you know what your IMEI number was, then there are ways to write that number directly into the phone. Need to send the phone to someone that has the hardware though. You can buy it yourself but it costs about the same as a motherboard replacement. Youtube "N7100 Android 4 3 imei repair z3x" to see what I'm talking about.
If you don't know the number, don't have a backup, then you'll have to change the motherboard.

You can find your IMEI number on the back of your phone though.. Pull out the battery, it's printed above your device's serial number.

I have my IMEI, i just wanted the solution through software can i change my IMEI or i have to go service center that would cost about Rs. 5000 minimum.
modem_XXDME4 is S3 modem, how can i flash it on note 2 N7100.
PLEASE HELP

@dineshdotcom2000 have you tried different modem? I had the same problem like yours and flashing my region's modem didn't solve the problem. I flashed European modem - modem_XXDME4 - and the dummy IMEI changed back to the original. Maybe you should give it a try.
Here is the link https://www.dropbox.com/s/5mrtz2c6s29ibxt/modem_XXDME4__.zip
I flashed the exact same file on my device and it worked. Good luck :good:

Find a service in india that has a z3x box. They can write the IMEI directly without swapping the motherboard.

just search, a few days ago there was the same problem solved probably in Q&A thread
