My RPI does not boot from SD card unless it is a recovery image, which fails to recovery it. During recovery the serial console shows:

Code:

The last seventeen lines loop a bunch, and then eventually it gives up:

Code:

 47.38 Recovery failed 47.93 USB-OTG disconnect 47.40 BOOT ERROR: code 4 - ''
When I try USB recovery it does this on the console:

Code:

And this in the terminal running the recovery:

Am I out of options? Is my device bricked?
