Kospet Kernel Versions

My Finow X5 is away to the jewelers in the sky (screen dead) so looking into a new watch.

Would it be possible for someone to confirm the kernel version of Kospets products please?
The Hope, Brave and Optimus (and if the Lite versions have different builds).
Just so I know what they are on for getting CFW running on it.

Many thanks

PS Any suggestions on which to get would be appreciated too
