If I ssh/sftp and corrupt some important files, and prevent it from booting up, how can I restore the firmware? Is there a flashable update file available for my device, and how can I flash it? If not, then can I do a dd command to backup and restore a whole file system image?do dd first before making changes.

You can backup your main root boot partition like this:
dd if=/dev/mmcblk0p1 of=/mnt/us/mmcblk0p1.bin bs=1024
flash update uses USB HID device. People are trying to discover how to use that. Not ready yet.
The k4nt has a diagnostics mode that gives all you need to fix damage to the primary partition, especially if you backed it up with dd as shown above. From diags you can just do same procedure used to enable root developer mode, but also fix your broken script, or worst case, use dd to replace /dev/mmcblk0p1 with you backup copy.
