Cannot boot into fastboot on VIM2 v1.2 using Fuchsia

I have been trying to install Kali Linux but have been unsuccessful because I cannot boot into fastboot, which as far as I know, is the only way to flash a new OS. After holding the left, third button like the instructions say to do, it goes to the Fuchsia logo and just does nothing. I’ve tried this with both a flash drive and a microSD card. I can boot into recovery mode just fine, however.

@Shidouuu which image are you using for Kali Linux ?
