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

*I was initially reading this as an indication that the sbl3 ended up being corrupted by the OTA. Or maybe one of the other primary partitions was corrupted and not allowing it to load. However, after running “fastboot oem erase_persist” in the Bootloader, the bricked device shows the same output as the working one.

Bricked
