about "return the love"plugin

Hello. I have bought a vu+solo and the seller stated its an original. I run the return the love plugin showing that my box is "authentication successful".
So is it ok?
The plugin needed 9 numbers but my serial number has only 8 so I put a 0 at he end.
Thanks for your time.

Thanks for the reply. It did not show "applied successfully (approved as genuine). Just authentication successful. I believe its the same thing but can you confirm it?

Thank you my friend. It currently on 1.7.9 black hole and I was thinking on flashing it with 2.0.2, and thats why I was asking, to avoid the brick.
I should create a backup prior and copy it to usb? Do I put a usb on and then go to settings/create backup?
