Hey for now I unlocked bootloader and downgraded to android pie, but I'm stuck to flash xperia xz3 on opensuse linux. When executing "sudo bash ./flash.sh"

Get error that fastboot missing (I have all required files in same folder including android platform tools). There isn't android fastboot tools for opensuse, so I forced to install "android platformtools" So I'm confused.

I have been read flash.md from github.
