Ok, after trying 3 different USb cables, including a brand new one I just ordered, and after uninstalling all drivers on pc and rebooting, then reinstalling, I still get these same responses from fastboot devices and fastboot getvar all

C:\ProgramData\LMSA\Download\RomFiles>fastboot devices
ZY224262W9 fastboot

and

C:\ProgramData\LMSA\Download\RomFiles\POTTER_RETAIL_8.1.0_OPSS28.85-17-2_cid50_s
ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml>mfastboot getvar all
