Help, After flash I locked my SIM card!

Hello all,
after flash my Note2 with official firmware especially for Orange (France) my note 2 being locked. I meant the phone doesn't recognize my SIM card. after that I rooted via CF-root method CWM based and install Wanamlite custom rom. That solved my issue and the phone come back alive.
A couple day later I decided to flash my device again with official release for my country( Bulgaria, mobile operator:MTEL) but again It doesn't work with my SIM card, any idea how to fix it?

You have to flash the older Modem attached here, with CWM.

Hello hagba,
many thanks for your help! It was very important for me and now I again use my note (but unfortunately only when the phone is rooted and patched with yours modem) .
I would like to ask you, who I can recover my phone to stock firmware without root, custom roms - just stock software.
Now when I'm trying to flash any offcial ROM, my phone goes to reset IMEI to service one...00449.......
I tried to flash with separate files (PDA,PHONE,CSC ) through ODIN but same result. Any idea?

My best guess is that you have to back up the EFS partition image and later when you go back to stock restore it back. You can back it up and restore with an application called, EFS PRO 1.9.12 Release, through your PC, just Google it.

Backup your efs just for safety. Then download a firmware of version DME6 or higher. Any firmware older than DME6 will cause the efs issues you have already experienced.

I flashed it with Uk stock rom from sammobile and it did not come with pit file.
The point is it was disconnected accidentally while flashing. So, flashed again
with HK stock rom.

Did you try to flash 4.1.2 over 4.2.2 by any chance? They moved the sdcard files to data/media/0 instead of data/media in 4.2.2.
Anyways to best way to fix this is to back up ur sd card to computer and Odin flash the original ROM that came with your device. (LTE hong kong version)

I did but it can not be fixed. It seemed to be lost something.

Flashing 4.1.2 over 4.2.2 is generally not a good idea. It will work if you first copy your sd card to the proper place before you flash a rom. For 4.2.2 it needs to be in data/media/0 folder. For 4.1.2 it needs to be data/media. It is possible to do this with a file manager with root access.
Odin will wipe your internal storage this is normal. The data/media/0 folder is not suppose to exist for 4.1.2 so it doesn't know how to deal with it. You need to format it back to 4.1.2 standards. As far as calls not working you probably need to make sure you have the right settings for calls and data to work. Odin should reflash the modem unless something went wrong during flash.
You should be careful when flashing things with Odin. Odin has total access to your device. Especially since HK ROMs are very different from the ones from UK. Make sure you got the correct .tar.md5 for your device. Check this list: http://samsung-updates.com/device/?id=GT-N5120 This is for N5120.
Good Luck. Worse comes to worse you may needs to triangle away and send to samsung.

Do you still get IMEI in place? If not, the call function would not work. Are you in HK or UK?
As suggested by nickdollahz, you need to copy out all the important files from "root" directory. Then, factory reset and flash again. Please note that factory reset will delete all your data.
For your reference, I'm in HK and has flashed the UK 4.2.2 rom previously (now the Germany one). I retain the original modem file of HK since I'm not sure if the modem of UK is compatible with HK's.

In the dialer, type *#06#, or in setting->about device->status->IMEI, it will display the IMEI no. Is it the same as that in the box?
Please also advise your current baseband and phone version in setting->about device.

That's why the call function does not work.
Please also advice the build number (i.e. last entry in setting->about device) of your current phone.
Before you flashed to 4.2.2 UK rom, what is your HK rom version? It should be N5120ZHBMD7, N5120ZHBME1 or N5120ZHBMG3.
Which version of 4.2.2 UK rom did you flash? And which HK rom version did you flash again?
Do you have EFS backup? If so, when did you back it up?

There may be two possible cases:
1) The EFS is corrupted. If this is the case, since you do not have backup, what you can do is to reset flash counter, factory reset and bring it back to Samsung service center.
2) the EFS is not corrupted and is simply a compatibility issue. I read from i9300 forum that Samsung has changed the format of EFS since July. However, I'm not sure if this is the case for n5120. You may consider to flash the UK rom again and see if the IMEI comes back.
You may try (2) and if bad luck, you can flash back to HK rom and do (1) above.
Good luck!

[Q] IMEI problem with Note 2

I have IMEI problem with my phone. I flash 4.3 via Odin, but this version is full with bugs. After that i flash with 4.1.1 and the problems start. My IMEI became 0049.. After this flash I flash with 4.1.2 - 4.3 but the IMEI is 0049.. I have EFC folder on my PC, but i don't know how to reset her.. I have and other problem, on my screen i have square with info for my phone - PDA ,CSC,BAND,MEMORY and other.
Can you help me to fix this big problem for me..

no one can help u to solve your problem... no one also don't care about this..
this is the kind of oldest radio board on the device. latest modem & kernel only can read new radio hardware. that's why it cannot detect the IMEI correctly..

Try flashing dmg1 rom

Changing the ROM will not change the IMEI.
And discussion of how to change the IMEI is expressly forbidded on XDA.

If you lost ur imei then read the posts by the user named Binary100100
http://forum.xda-developers.com/search.php?searchid=239699708
You may get the imei back by installing a 4.2 rom. That user somehow was able to make it work by installing two 4.3 roms without formatting partitions but no one understands why it worked.
If you simply have no data then follow the instructions below to odin flash a new GSM modem

Yes, and nothing help, many friends asnwer, but no solution yet

If the phone is running the latest bootloader and modem, there's nothing you can do without the developer's help.

Your efs is corrupted. Read this , it should help you fix your issue https://forum.xda-developers.com/showthread.php?t=2420881&page=17

The phone is running now Eclipse rom v9 and working fine, but when i flash the MIUI 8 rom
Lost the IMEI.. Did i miss something!?

Sounds like miui isn't compatible with the phone.

I tried something else
Back to stock rom and then flash the MIUI8
The same problem lose imei
