I unlocked the bootloader on my phone and installed twrp according to this description:
https://forum.xda-developers.com/honor-note-8/how-to/huawei-honor-note-8-unlock-bootloader-t3488142
Later in twrp, I wipe everything except the SD card. Later I installed your ROM but I think the phone did not reset twice. The system has started, but I do not see google app (play store and others). I installed a google store with HiApp. I installed Root Checker and says I do not have root. I do not see AdAway either. What could have gone wrong?
EDIT: After that i installed SuperSu from you link in first post (by twrp). Then I installed AdAway app. Now I have root and add blocker. I must install gmail and few other applications and I'm happy. My phone still works

I think if all works good I will wait for You now version of You ROM.
p.s. After all, I'm curious what went wrong with installation ?
