we tried to do a full system recovery by using the rommon command "erase disk0:", then the internal EMMC flash disk file system can't get mount during the boot.
When we tried to load image through tftp(tftpdnld) or external usb flash(disk1:), at the last boot stage, the system tried to write a file to disk0:, it fails then the system reboot. I tried all the OS version from 9.3.2 to 9.14, all comes back the same result.
you could found it here:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog – try
dmesg | tail or so.
mount: /dev/sdb1 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error

This can be fixed by upgrade by upgrading the firmware to 1.14 and later. but we can we upgrade it in rommon method
