[OnePlus 7T Guides, News, & Discussion] ricksrod:
Has anyone successfully rooted the HD1900 device?

I've followed all of the steps provided, I can boot the patched boot image, then install magisk manager, at this stage when I launch magisk manager it shows that magisk and the manager are already installed. I choose to install magisk (direct install), this works so I reboot the device and when I open magisk manager it shows that magisk is NOT installed.

Any ideas?
