Did you backup efs? If you did restore it. If not then try flashing this in recovery.. Or try flashing stock again.

Actually it IS possible for the n900, the knox reset also let's users downgrade if they so choose to.. But he doesn't need to downgrade, he lost his efs/imei and that can be fixed if he made a backup or by using the other options that I listed.

Do not try to recover EFS...
It is not the problem, the problem is that you have unknown baseband (Modem damage)... Please check if it can mount /EFS folder (Check in recovery)
It it fails to mount /EFS, then you will probally need to find someone with a Asansam box to fix it...

Remember to backup you EFS folder

Best regards

IMEI null/null comes from modem failure. It is not because your EFS is wiped, if your EFS was wiped, then you would get a generic IMEI number 0044.....
But try to go to recovery, do you get "failed to mount /EFS"

But your IMEI null/null could also be a hw failure...

But I would try to flash a 4 part 4.4.2 firmware
Remember to backup your EFS, it is not corrupted...

IMEI null/null has nothing to do with a wiped EFS. It is modem problem, or HW failure. I would start flashing a 4 part firmware, eg this one

Hi friends. I am new to xda. I have same problem last 4 months. I have tried flash different stock roms but no use. When i check phone info it showing
Original CSC is INU. But showing other CSC is THL (wrong). Modem is blank. SW Version is unknown. My guess is modem and csc related issue. I have tried flash modem, but not affected. CSC also not affected. Why this happen?
