Nexbox A5 s905x root stock rom 6.0 with Magisk and phh's SuperUser

[lost2]

Hello i just manage to root my stock rom of A5 nexbox 2GB/16GB with TWRP running from sd card.
1st download this files
- TWRP from here http://www.memoryleaks.org/libreelec.tv/twrp/ (thanks ladyjack for point at this and JWhitebrook)
- Magisk V8 and Magisk Manager from here http://forum.xda-developers.com/apps...mless-t3473445 (Thanks topjohnwu for this)
- phh-superuser-magisk-r259.zip from here http://forum.xda-developers.com/apps...d-pay-t3435921 and phh's SuperUser Manager from here https://play.google.com/store/apps/d....phh.superuser
(thanks topjohnwu)
put all this files in root of sd card
rename the twrp.s905x.img to recovery.img
install Magisk Manager and phh's SuperUser Manager WITHOUT running them
shoot down the media player , put sd card in slot, for those who have the recovery button push the button plug the power and when see the logo count to 3 and leave the button.
in TWRP install fisrt the magisk_V8 without reboot the phh-superuser-magisk-r259.zip, if you wont wipe/cache and reboot, thats it.
I test it with Titanium , quick reboot, busybox , root explorer, all have root , the only apps it can't take root is es file manager ....
