Those videos only help with the STUDIO XL2, not the Vivo. Look, i'll make it simple. To open the phone you have to pry from the front to the back plastic. Ever taken apart a Galaxy S4? Just like that. Watch a video on the S4, that'll show you how to take apart the Blu Vivo XL2. It's about the same inside too. Well, no probably closer to a One Plus One/Two phone inside, but to open it, pry from the front latches to the back.
