evic vtc mini firmware update

Hello guys im new to this and this is my first post. I've been searching for this type of problem but didn't find anything. So yesterday i got my Evic VTC mini (its my first vape btw), and i was pretty good. So when i got it home and I saw in google that there was a update for the firmware. But...

In this video I go thought the new V2.0 Firmware for Evic Vtc mini Show you whats new and what has changed and How to Install it

Can I use a tablet to upgrade my evic vtc mini? I dont have a computer just internet and my galaxy s3 and s5. I've got a friend who will let me borrow his tablet. Or could I do the update on a library computer ? Thanks for any help.
