Hello, here I am recovering a Vu + solo pro from a friend, he bought it on the website of Ali Express.It is planted at startup with the gear that turns on the top left of the screen.

I would like to flash it, but I do not know what image openpli put because I think it's a clone.

I opened it, I do not see any sim.

I do not know which versione is this the V1 - V2 or V3

I would like with the opinion of specialists to know what I can do with and if you have a link or backup, I would be interested.

Thank you in advance to all
