I believe that the first step , installing bootloader extension, will work on
any Viper 4K ... V20,V30,V40 ! then user must adapt the /backup image
to his real model ! The only thing that bothers me is the RC !!! if we don't
have a Dinobot RC ... the procedure is useless !
Regarding the return to the original state ! it can be done using the
"recovery image" I've posted ! it was tested on V20 and V30 and is
working ... is reinstalling the original boot context for V30 but after that
you can reflash any image for V20 or V30 as well !
