Nexus 7 2013 - adb shell tail ./etc/fstab

*Not only does /dev/block/mmcblk* not show up here but neither does the file system format and yet again /persist is in the list. After “fastboot oem erase_persist” that line is gone but nothing else changes.

Bricked

E:\android_development\sdk\platform-tools>adb shell tail ./etc/fstab
 /system ext4 rw
 /data ext4 rw
 /cache ext4 rw
 /usb-otg vfat rw
 /persist ext4 rw
