genuine vu+ solo2 or clone ?

New to vu + equipment and seeking advice
Is there any way to tell if the second-hand vu+ solo2 is genuine? Now they’ve made clones of them
I’ve been assured it genuine and purchased before clone were out, but I would like to confirm it
I’ve only every purchased genuine dreamboxes in the past and i can visually sport a clone a mile away (even the remotes)
But not idea on how to identify (visually) a cloned solo2 due to not seeing either before
I take it if I flash it with original images (none patched) It would error because of ssl or is it not the same on vu+ receivers?
Thanks for your advice
