Can I do this from my phone if my tablet doesn't turn back on?
I doubt that would work, unless you can research and find something, would your tablet be under warranty, you could report this as a fault if your tablet does not turn on at all, you can boot it up from the guide I sent earlier, and choose to power on the device and get whatever you need off of it, then reset it to the factory settings to get rid of the virus'.
