The -w option writes only the memory blocks which are written by the original
radio software, in the same order.
The -W option writes all memory, possibly allowing overwriting of calibration
data (if there is any) or other data which may be critical to the proper
functioning of your radio. I have used this on my radio, and it still works
but please be extra-careful.
The -W option is a bit more brave, it writes all memory upto 0x1d00. I _think_
that the radio has calibration data above this address, but of course this is
not certain, because this knowledge is a result of reverse engineering, and not
information from the manufacturer.
The -B option is the "brick my radio" mode. It writes all memory, possibly
allowing overwriting of calibration data (if there is any) or other data which
may be critical to the proper functioning of your radio. I have used this on
my radio, and it still works but please be extra-careful.
