For people that have had issues updating to this release using | LumiaWOA Announcements
For people that have had issues updating to this release using driverupdater:
Make sure you are using the latest version of the Driver Updater Utility
Make sure your uefi is up to date (https://github.com/WOA-Project/Lumia950XLPkg/releases)
After the update, check device manager
For each device with a yellow warning sign (yellow bang) right click, uninstall device, do not tick the option to also remove the driver. Repeat for all devices
Under USB devices, you will likely see a duplicated Type-C controller driver, find the one whose instance is ROOT\Tyc\1000 and right click, uninstall.
Reboot the device
Background:
The bulk of these issues are caused by an oversight/bug in previous versions of driver updater. If they were used in the past on the installation on the phone, drivers would be permanently sticking to the install and thus the update process would either not update any device, or would duplicate the devices, leading to issues
