na, you dont need to delete that to flash a custom recovery(i never have, in my 6 years with android, and all my devices). is fastboot seeing your device? kkdo you see fastboot going through the process of flashing a recovery? if you are typing it right, and fastboot sees your device, you would have flashed a custom recovery. when you connect to fastboot, type.. fastboot devices. if it sees your device, its id number will be shown.
Yeah you were right. Driver issue. fastboot devices showed nothing. Reinstalled drivers and looks to be good now.
Thanks guys sorry for the post in wrong area
