I do not understand what you mean by " i lose my root password to enter in recover mode using command + s".
Recovery mode is Command + R.
To recover the Admin PW:
Correct when i press the key command + R, so fast comming up a screen asking me a password and i don't know how can i do to resolve this screen blocked , i cant access to Recovery Mode
Do you have firmware password set?

I remove the macmini memory card and press Command + Option + P + R and i cannot reset the password firmware, how can i do?
What model Mac? Only with the older ones does removing memory reset the FW PW.
For newer Macs see:
If you lost or forgot your firmware password - Apple Support

If you forgot the Firmware PW for your model Mac yo have to contact Apple as the link in my previous reply stated.
