How to Extract boot.img from Sharp Z3 Fs8009? I'd like to extract the boot.img from this device in order to root it with Magisk.
Is it possible with adb commands?
Or another way maybe?

The firmware on it is 00WW_1_310 global version, and I can't find a place to download it and extract the boot.img.
The only link that had it is dead.

There's no custom recovery, the bootloader is locked but there's a way to unlock it with ntool.

Thanks for any help
Better yet, check this link there root for Sharp Z3, only it is in Chinese language. The good thing is that I was able to download the files they use there because there is a link to do.
