You don't use adb at bootloader, it's fastboot.
okay, now i'm getting somewhere. thanks for your help! i was trying to follow the steps exactly, but it turns out i can skip the adb since i'm already there. duh!
ok here is the other problem, the problem i was running into yesterday before i gave up:
when i flash the img. i get this:
Asads-MacBook:~ asad$ cd /Users/asad/Desktop/walleye-opm1.171019.021 ./flash-all.sh
