You likely have bad flash since the CRC error can also happen if you have bad flash that can't be written correclty to.
First you need to check what firmware you do have on the switch. There is usually an option in boot menu for operation code status. May want to check that and post back what firmware version you have on there first.
Second, the dev OsapiFsUtils command will only work once you are at the enable prompt.
that article is basically to free up space on the flash. You can always flash the backup image to work around that. Make sure you don't try to upgrade to 10.x code since the v1 don't have ability to load that code up. (too old of hardware). Use 8.0.3.x
