We know about the new wireless controller Cisco WLC 9800. We are going to discuss about the password recovery feature in Cisco Wireless Controller 9800-40.
Software version = 16.10.01
Step1:
Reboot box
Step 2:
Send 'break' key when you see ##### print on console for system loading image. then, system will breakup boot and will go to rommon prompt. (this can be done using putty or send break key)

Step 3:
Change config register, to 0x2142 using command "confreg 0x2142" from rommon prompt.
rommon 1 > confreg 0x2142
You must reset or power cycle for new config to take effect
Step 4:
To save rommon config change, execute "sync" at the rommon prompt, "reset" rommon to applied change from rommon prompt.
rommon 2 > sync
rommon 3 > reset
