 ## Adding support to configurable SW and HW versions, Vendor ID and much more
-`/etc/scripts/flash` can be flashed in order to add support for some variables implemented in `omci_app` but removed from `xmlconfig`. The patch is below (change the values to suit your needs)

 ## Increasing the length of the software version from 13 to 14 characters
 `omci_app` has an hard-coded limit of 13 characters for the software version, which is too low. We can binary patch it to increase it to 14 (or more, if you dare/need)
