Lets clear. You had 2.3.6, than you instaled 4.1.2? And problem was there from the begining of use 4.1.2 or you had signal on 4.1.2 and it suddanly dissapear?
Try to reflash firmware, but do not use the one you have - download it again. Do factory reset, clear cache and see if it solves. If not maybe that is some hardware problem.

here is the problem appeared with version 2.3.6 it was normal then one day I find this logo banned therefore I flash with version 4.2.1 and nothing changed.
I did re-flash with a different orginal version 2.3.6 that I installed before and see what it gives as you told me.
Otherwise just a question when I am version 2.3.6 or 4.2.1 when I plug the usb cable it makes me MTP connection or MTU esque top is this normal?

That is normal, on JB you can choose between connections.
Is your phone locked to network provider? That you can only use its sim cards?

So you are from 2.3.6 then you flashed 4.1.2 then you just flashed 2.3.6 back? You should follow the downgrade steps, you can't just flash it like you flash 4.1.2.
Correct me if I'm wrong or misunderstand anything.

I do not know. Now you are unrooted? Check download mode if you have binary counter increased, if not then ok. And if you have warranty go to service center.

Hello guys have a question for you.
I installed Kies on my PC a few days ago. I connect my Note and everything seems fine, I can browse the device, see my memory usage, see the firmware version that is installed, etc, but every time I click on the firmware upgrade and initialization option I get a message box saying: "GT-N7000" does not support initialization.
what does that mean? That I can't use kies to update my device?
I know my device is rooted but I guess I still should be able to use kies to update my device, right? am I mistaken?
I have the same problem.
I also see the same message when I hook my one up
Sent from my GT-N7000 using xda premium
im on the stock unrooted german ICS, when i connect to Kies it says that "your device does not support software upgrading via kies!!!" anyone know whats up with that!?
Erase Kies that you have right now, go to Samsung.de (german site of Samsung) and install their latest version of Kies. Open Kies, run device updates in Kies and reboot your phone and THEN connect phone to the computer via USB cable. I had the same message and this solved my issues.

Had the same problem was on indian (inu) version of gb and upgraded german ics.... had this message also.
I changed my csc code to dbt and it seems to have fixed that.
this is what i did
in dialler type
*#06#
this gives imei number note it down
then
*#272*your imei from above#
select dbt and hit start.... does a factory reset though so be warned
also i am a noob so cant garantee that this is safe, this worked for me now when i connect to kies i get the this is the current firmware message, however i dont know if its safe, my phone has never been rooted also.
just need to fix the charging paused voltage to high message without having to connect a usb stick conector and removing it now.

Hi guys! I need your help. I read the forum, but did not solve the problem. I'll tell you more. Bought on ebay LG P970. I do not know what it KU5900. It was a firmware Android 2.3. Using the program LgMobileSupport put updated to version Android 4.0.4 After the update the phone does not boot, the screen inscription "olleh". I read the forums, and using a program SmartFlashTool put firmware lgp970_v30b_cis. The phone is loaded, but does not catch the network 3G. In 2G often loses the signal, especially from the base stations within the network. Still trying to reflash. Put Korean radio module firmware KU5900_CP.fls, and bin file European lgp970_v30b_cis_ap.bin In this case, the phone does not see the Sim card. If I put the Korean firmware V30I phone does not boot, the screen only logo LG. Tried way from here http://forum.xda-developers.com/showpost.php?p=33881192&postcount=643 - also does not see the sim card. I understand the problem in the firmware radio module, how can fix this problem? Thanks in advance for your help.

I got mine to work after struggling a little, after you have flashed V30I, let it start and stuck at olleh thing, unplug it from usb then remove battery, put it back then press and hold VOLUME DOWN + G + POWER, When it start to reset release those buttons, wait a little and waaaah, the phone will start with korean language and everything will be ok

Sorry my english, I'm using google translator. I had a similar problem to downgrade the Jelly Bean for Gingerbread, NV.DAT changing the file inside the folder / modemfs which changed the PCode XTC (Phillipinas) for ZTM (TIM Brazil my region).
In Gingerbread 2.3.6 simcard was usually recognized and upgrade to 4.1.2 Jelly bean simcard stopped running. Could solve to find that the file was originally NV.DAT GB in 302 bytes and 288 bytes in JB, but in my case it was always 302 bytes in JB, got a backup folder / modemfs the same region and that my only replaces the file, restart the usually recognized my simcard.
Go to recovery mode.
Turn off the phone
Hold the Volume Up + Home + Power button
Let go of the buttons when phone vibrates.
Use Volume Up and Down to navigate, Power button to select
Choose Wipe Data -> Choose Yes
Choose Wipe Cache -> Choose Yes
Reboot Phone.
All issues will possibly go away.

First of all flash stock rom via odin and then check all working fine or not?? If evry thing working perfect then try again to install custom roms...
Well, I flashed the stock ROM from ODIN. I downloaded it from that Samsung hub website (don't remember it's name now). But still the problem is the same. I am not getting any signals. I did installed the ROM made for India, but still the issue is the same. Is there anything else I can try. I am now non-root with stock Samsung ROM.
@anshumangoyal Check IMEI Number under setting - About Number
I can see my IMEI Number with *#06# but there is xxx under base band. I installed the original ROM, then Rooted my phone and installed custom ROM. Still the baseband shows xxx. I am still not able to receive the signals on my mobile. Is there anything else I can try here?

Using a terminal app in your phone / adb shell , type this.
Code:
mount | grep modem
then screenshot the output.
The expected result is (may differ),
Code:
