Help with root

[SiParle]

Every time i try and flash Super su or magisk it fails, TWRP is unable to mount anything and when i try to reboot TWRP says no os installed. I then have to flash stock recovery to get the phone to boot normally, I have rooted phones in the past but i just dont get why this is happening. Can anyone shead any light on this please

Phone and FRP unlocked
P8 lite 2017 8.0.0.383(C432)
Android (stock) and EMUI version 8
TWRP 3.2.1.0

I don't think the normal root method works anymore on genuine EMUI 8. I believe that we need to flash Askuccio's TWRP (hard to find without knowing it exists already), and then a custom treble rom (of which there are many), and then flash magisk over it. Not too difficult, but personally I've been having troubles with actually booting into custom ROMs.

I can't flash the Ashuccio TWRP - keep getting FAILED (remote: partition length get error)...any help?

You have to type to flash: fastboot flash recovery_ramdisk TWRP-3.2.3-0-Hi6250-Askuccio-v1.0.img

Dru79 - now that I have TWRP - and many thanks for that, would you guide me quickly through the next steps for a custom ROM (I have read all sorts of posts that say you have to flash stock then a ROM then do all sorts - things have REALLY changed since I did this last!). I am on And 8 and emui 8 and want (ideally) as close to asop as poss with the ability for adoptive storage a must. Just unsure exactly how to progress, ie is it super SU (which most now seem to say no) or magisk etc....I really would appreciate a simple guide.

Thanks
