Any way to restore from corrupted EFS Partition (Backup Lost)

So basically i thought i had a backup of my EFS through Philz Recovery before i started to root and flash Darkstalker Rom V5. Well i ticked the option to fix the EFS partition in the aroma setup box and after installation, i see that i have a corrupted IMEI and Serial Number. I transfer the backup to restore it and to my surprise, it contained system, data, and cache but no efs. What are my options here? Any help would be appreciated..

Have you tried Odin to stock?

Odin to stock!

Recover efs manually with old Backup

I lost the funcionality Phone in my N8000. I think i lost the imei e someone more else. How can i restore my efs? I have a backup of my efs in format zip and format tar made 5 years ago ( i dont remember what application i used) , but i can not install via Odin or via Twrp, said Invalid Zip format on checking Digest File. I think the problem is checking the md5 generation that is not compatible with Odin and Twrp.
Someone can help me to restore the /efs partition with old backup. Thanks

I resolved this situation, using Solid Explorer and Qute Terminal with root.

Thanks

It is not solved, when reboot the system, the imei of phone, N8000 is another, is from another file from i used to recover.
Manually from my backup what files and permissions i have to copy to the /efs in root of my N8000? First i copy nv_data.bin, nv_data.bin.md5 and the folder /imei and works. I do not known the original permissions of the files, perhaps now the problem is this.
Someone can help me?
Thanks

With this guide "[GUIDE] Recover your IMEI in 9 steps. " https://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 , i resolved my problem with imei, no problems with reboot, but now i did not have access to Wifi, i can not connect to my Wifi Network.
Someone can help me, how can activate wifi? What files i need to copy from my backup? Before clean the /efs i made a backup the old efs.
Thanks
