I just got the phone today. i unlocked it with the ASUS-provided tool. No problems. I enabled developer mode and USB debugging, no problem. I can see the device when I connect it to my PC and type "ADB Devices". No problem there.

My problem is when I enter FASTBOOT mode (vol-up + power). If I connect the phone to my PC and type "fastboot devices" it comes up blank.

I tried multiple versions of ADB/Fastboot, and multiple cables and ports on multiple computers. The ROG phone just isn't recognized by fastboot (My old Pixel XL is recognized by Fastboot on the same PC).

Does anybody know why the ROG Phone isn't being picked up by fastboot when adb works fine on the same machine?


[UPDATE 1]: I also updated my USB driver and the device is in Device Manager as ASUS ADB Android Device when plugged in as USB debugging. When in Fastboot mode, the device does not show up in Device Manager at all.
