Two days ago I tried putting #UBports onto it. It appears that the way I was able to run fastboot format cache and fastboot format userdata on a #Windows10 machine but not on a #Ubuntu18 #Workstation seems to have made that device impervious to the UBports super easy installer.
It worked great on my old #Nexus5 so I'm at a loss as to how I can proceed. Maybe the 7 is damaged internally? I tried the #UBportsInstaller with and without the wipe checkbox checked, as well as with and without the paths to the adb & fastboot executables.
