You can't use adb in fastboot mode, use fastboot commands in fastboot mode.

 

sorry newbie here... where can i use adb to recover my coby kyros 8065...

i got stuck on coby boot.... please someone help me

 

Have you tried factory reset from recovery? you will lose all data but may recover your tablet.
you don't need adb for recovery.
Good luck.
