Hi.. unfortunately I have the same problem. After rebooting my phone, I've lost my IMEI and my baseband. Any chance you can help me out? I would really appreciate it !
I have my IMEI on my phone package, but the tools, that I've found, are only able to load backups. I haven't found a way to restore my IMEI without a valid backup file.
Thank you

Edit: my phone is also a MI4
Edit2: My WLAN MAC address is also "unknown"... Is it possible that the internal storage, which holds the encrypted data like IMEI and MAC address is defect :/?
I am having the same issue with my mi4w. Invalid IMEI, i flashed incorrect rom and now facing invalid imei. Can any one help. FYI, i have rooted my phone and have IMEI number with me.
