Hey everyone,
I'm planning on getting Magisk for my Xperia Z3 Dual. Now before I start doing literally anything, I want to ensure that if I screw up, I can flash the original boot.img back onto my device.
But right now that's my problem.
I can't seem to find a way to get the stock boot.img.

I've been looking around the web for a while now and everything I found required either a custom recovery, like TWRP or an already rooted device. As for the custom recovery, I'd be all for it, but I read that TWRP is only available unofficially for the Z3 Dual and requires a custom rom.

Is it possible to backup and get a boot.img from my device without literally changing the entire system already?
