Do you have to use SP tool to flash these phones?

Do you have to use SP tool to flash these phones? I only have the command line adb/fastboot utilities available as I use a mac, is it possible to use these?

Found this:

But I can’t say anything more, never owned a Mac.
Just a warning, avoid flashing the preloader

Thanks, I’m familiar with how to flash normal android devices but I’m not familiar with the scatter files in the TWRP directory and wanted to make sure using “fastboot flash recovery recovery.img” would work and not brick my watch :slight_smile:
