Install supersu app if it is not installed. By the way what method you used? CFRoot method is already packed with clockworkmod, supersu.

You're supposed to backup EFS before you bork it. Once it's borked, you're boned. What you're trying to do now is futile.
You have two options; service center or contact Odia by PM (and wait patiently for a reply. If you harass him he'll probably/quite rightly ignore you) & he might be able to recover it for you for a small donation (cheaper than paying Samsung/authorised repairer to fix it).

Using sometime else's nv_data.bin file won't help you. That file contains unique information for your specific phone, including your IMEI number.

In info section is says: Unknow baseband

Agree with @jaidev.s - check your imei, If it's corrupt = OH DEAR! unless you made an EFS backup?

One restore your backed up EFS folder or try factory reset or flash stock rom ,
Fails then get a price from service centre to repair .
Or get your very stupid friend to pay .
No idea what phone you are using do you know .

No ??? admittedly few in number have resolved EFS problem by factory restore or and flash stock rom .
As the OP has flashed firmware for another phone it could well be more than just EFS i am afraid .

I tried it before. The first thing I did was restore. But same **** = no connection
So there isn't any other way?
If you flashed a wrong firmware you may have messed up your partitions, hence why you have lost efs.....so if nothing works a flash with pit maybe necessary....but I strongly suggest trying all other fixes first.
i will try stock rom now. but maybe i have to format everything? so that new rom maybe fix it?

If you haven't backed up your EFS, generally the phone needs to be sent for repair.

warranty is over date. Please help me to give any info that might help.
Samsung generally offer a two year warranty .
If you failed to backup EFS then first try flashing stock firmware .
Fails then search read the multiple EFS/ IMEI posts on here as some claim to have fixed .

Simple lazy boy method .
Take it to a service centre you cannot repair an IMIE /EFS with no backup .
you do have a habit of breaking phones judged by previous posts so let some one with some skill fix it

If you do that you will probably end up paying for a new motherboard, take the advice you've been given and pay for the repair - or not, it's your choice.

new locked s3 want to unlock having problems..

So it was originally on 4.3 and i was told to downgrade to 4.1.1 to unlock it so i did..
I ran the GalaxSim Unlock app to unlock it but its saying invalid IMEI now :/
I dont have a backup of anything what can I do to unlock it..
Thanks.
You should to install 4.4 version to unlock it. It is the latest version.
How would i do that?

4.4 won't help anyone, you can't downgrade to 4.1 without an efs backup to restore. Pay for a code.

Well I know the imei number its supposed to be (on the box)
anyway I can restore that?
Usually when the imei is invalid it means you have damaged the /efs folder, the only way to repair this is by restoring a backup.
However first try flashing a stock rom again, just to be sure, if it's still invalid then the problem is definitly the /efs folder. Because the /efs is specific to each individual phone there isn't much we can do. Moral of the story is to make sure you make a /efs backup. The app you used should have a tool to backup the /efs folder, and this should have been done before trying to write to it.
I did copy the efs folder to my sd card before doing anytjing with it...
But copying it back just made it have yellow text on the homescreen...
I tried reflashing back to 4.3 but no solution...
EDIT:
After copying it again it made the text go away but my IMEI is still 0049...
Any help?
edit2:
FIXED IT, Got the IMEI back
Is there any guide now on how to unlock the phone? Currently on android 4.1.1

No, the phone is rooted and has a custom recovery.
I want to SIM-Unlock it so I can use any networks sim on it.
The easiest and safest way is to contact the carrier whom the phone is locked to and ask for an unlock code, they should give you it, but might charge (I'm not sure how much.)
Try to do the nv_data.bin method.
You won't find the md5 value in the log (Samsung patched that a while ago), instead, run this on a Linux machine (or in the Android terminal):
(cat nv_data.bin; echo -n Samsung_Android_RIL) | md5sum

Samsung updated the efs in one of the 4.3 roms and above. Your 4.1 rom doesn't recognise it as the 4.1 rom cannot read a V2 efs and since you started out with a v2 efs you cannot do anything with Rom versions below 4.3.
Restore your original rom or install a custom 4.4 rom regain your imei and either pay for a code or contact your carrier. This app is useless in your case..

I actually went into my local town, went into one of those "phone unlocking/repair" shops and paid £15 to get it done. Was done in 30minutes and works beautifully.
