Restore your backup of rom
If you dont have it. Flash stock rom through odin.

All attempts failed!!
Restore your EFS!
Flash Stock rom via Odin
If all failed i think, need to return to service center, you will get your phone working again.
Hi I have restored my efs I really need a qcn backup please
anyone please help
Has anyone been able to solve this yet?
I have same 000000000 issue.
I hear you say reinstall fresh stock rom, via odin, however, please explain how that will solve the problem?
I'm worried I can make it worse?
As a side note, I have another n900t that is fine. If I would get some steps, I would make the qcn backup, delete my information from the proper place, and forward, IF this is a viable solution. ...?
Be well.

You cannot use EFS folder from another one... You have a couple of solutions
1. Sent it to a Samsung Service center, or other repair shop who has special service equipment
2. Buy a box, Asansam/Z3X/SPT etc, remember to also buy a UART cable...
Please note:
If you buy a box, then you will not be able to just rebuild your originally IMEI, you will have to use Super IMEI. and you will not be able to flash a modem to the handset afterwards, as the solution will patch your modem. So every time you want to flash a new firmware, then you will have to modify the firmware package

No it isn't possible cause of the bootloader. It wont let you downgrade your device... simply impossible I think, sorry.
But here is a thread about that, maybe it can help you too: http://forum.xda-developers.com/showthread.php?t=2744061

What does it makes you think this has to do with EFS partition? What did you do? What firmware are you running? When did the problem started? You need to give more detail in order for people to help you...
