Please help me restore Samsung Galaxy Note II GT-N7100

I have a Samsung Galaxy Note II GT-N7100 that has an issue, no baseband info or IMEI.
So I tried to repair it. I found a tread about EFS restore/repair here in xda-developers and downloaded this software:
N7100_EFS_Backup_Restore_WIN.zip (Please see the attachment)
First, I created a back up named "efs_ORIGINAL.img".
And searched on all forums for helps. I got an "efs repair.img" from a forum through 4 shared website and did run Restore_EFS.bat.
After that my phone no longer boot to OS.
I tried to restore it with "Restore_EFS.bat" but it failed.
I tried to restore it with Samsung Kies software (Tools -> Firmware Upgrade and Initialization.). It said "emergency recovery of firmware completed but stuck on samsung logo. It looks like restored to factory settings excepts efs.
I also tried Odin to install the OS. It said "PASS" but it stuck on samsung logo. It looks like OS is installed excepts efs.
The ISSUE now is /efs is corrupt. The phone need to restore it.
I got to recovery menu (Vol up + Power + home buttons) and tried factory reset.
it said:
---Wiping Data---
Formatting /data...
E:failed to mount /efs (Invalid argument)
Formatting /cache...
Data wipe complete.
If I go to recovery menu. I can see these at the bottom:
E:failed to mount /efs (Invalid argument)
E:failed to mount /efs (Invalid argument)
# MANUAL CODE#
-- Appling Multi-CSC...
Applied the CSC-code : unknown
Successfully Multi-CSC.
Please help me to restore efs.
Can i use ADB to restore my backup efs.img ?
Thanks in advance!

UPDATES
After waiting the whole day for help, I finally repaired my phone's efs partition using TWRP 2.6.3.2.
My phone does boot to OS and works all functions.
But
baseband is unknown
IMEI is null
Hope someone here in the forum could help me with it!
Thanks!

I am honestly not sure about the firmware version, but I'm sure it's from the Philippines and from the carrier sun, it must have been xtc.
Anyways, I managed to make the phone boot, now my problem is that the phone feature is gone, because it now uses the generic IMEI ane some random serial number.
Also thanks for your reply.

After I install this firmware, would that fix IMEI? Or do I need to do other stuff?

sadly, it wasnt able to fix my IMEI, it still stuck on the generic IMEI number which is 499... if you have any other ideas please let me know.
Things I have tried:
*change IMEI via adb: I couldn't enter shell, says access denied.
*generate IMEI then restore via NV_read/write: the application coudn't detect my phone, when trying to set the usb setting to RPNET+DM+MODEM, the phone instatly changes back to MTP.
*try the adb code via terminal emulator: all terminal emulator apps force closes.

Emergency.!! Lost IEMI no. Signal not working after unbricking A6000+..Help>!!!

I am Using Lenovo A6000 Plus ,,After flashing MIUI rom in it I update the Rom throught OTA update ,then After i founded my phone dead;
but i was able to unbrick it through QFILLs by flashing "A6000_S035_150507_8G_ROW - 1" that is of Lenovo a6000 but after this i losted my network signals and ,speaker and mike are not working properly..
I thought it is because of the Frimware of lenovo a6000,then i Flashed my Backup Of lenovo A6000 plus through TWRP but still the problem remains same...
Then I visited to Lenovo Service Center They said me that your Phone has lost its IEMI no. and warranty is void,and they can do nothing for it ,and only sol. they suggest was to change the whole motherboard (Rs=6000). That is 90% of the phone Price
Is there is any way to repair My IEMI no. and my phone Plz let me know becuase you guys are my last hope. if you want any more info you can Test me Personally,...

Which firmware file (version) did you use to revert it back ? S143, S288? VIBE? ROW?
Did you use a separated modem file?

download the file i shared earlier on NON-HLOS.bin and replace it with the copy in your stock firmware and QFIL again, that's what I did earlier on to regain my mobile signal.

Had the same problem with a Galaxy Note 1. It's a hardware fault, you need to take it to service, no software flashing is going to fix it.
