Asus max 5.5 adb won't recognize device after unlock bootloader

Hey guys so I have encountered this problem multiple times. Followed this thread for unlocking bootloader and initiating root: http://www.symbianize.com/showthread.php?t=1411778 so far I went up to unlocking bootloader successfully without any hindrances but to my dismay after unlocking bootloader, adb won't recognize my device and can't proceed to flash TWRP. Tried rebooting to fastboot and typing in cmd adb reboot bootloader but did not proceed because as I said the device isn't recognized. Using windows 8 64-bit. Device is Asus zenfone 3 max variant 5.5 (zc553kl) updated to latest firmware nougat 7.1.1 I have usb and adb drivers installed, but the device doesn't even show up in the device manager, so adb reboot bootloader didn't find anything to reboot. Any advice would be helpful. Thank you!
