Trouble flashing my Keyboard

Hey. I just finished building my DZ60 and am currently ahving trouble right now in flashing it. I have downoaded drivers and looked at different forums; however (apologies I dont have access to commas due to my boards present state) I have my device connect to GMK toolbox only to be told “no device present”.

Please help

you need to reset it. try pressing spacebar+b at the same time while QMK Toolbox app running.

btw, why is 1upkeyboards/1up60rgb selected? nvm.
