It's rooted but you can uninstall Magisk.
Yes final EMUI 3.0 has been sent by OTA to beta testers. I have it.
I have found why ChevronWP7 is crashing !
Spybot Search and Destroy has flagged hosts file in read only mode and ChevronWP7 is writing this file !
Try to go to C:\Windows\System32\drivers\etc and remove read only flag if you have the problem
I have installed Nova. Pixel is unusable (on all ROM) it looses icons of apps installed on SD card at reboot.
The cards don't need the plastic to be in position ! Push them more in the holes, you must have a "clic"
