Check if you have sim in your phone, you have to take it out. And try this step if you still have that error, press *#0808#, and choose RNDIS+ACM+DM+ADB, and run the process again.

I have the same problem when try to write cert to n920t. My problem was solved when I try above steps.

Of course IMEI is zeros. Unlock erases EFS data partition. Did you backup CERT? Write it back. Didn't backup CERT? Sell box.
