Windows 10 images for Lumia 950 and Lumia 950XL updated with improved drivers

The hackers behind Windows 10 and Windows 10X for the Lumia 950 and Lumia 950XL have released updated images and a new driver pack for the devices which brings a number of bug fixes and improvements, with Gustave Monce calling it their most stable release yet.

Recently I made an update to the drivers used in the LumiaWOA project (https://t.co/FgdhyzsUwq).

This is our most stable release yet I think, and for the occasion we made available a lot of FFUs so users have the choice of the OS version.

Clean ups, bug fixes, Bring up to spec

Unfortunately, Windows 10X images are not included in this release, but (a bit like the official version) they may be released later.

The update brings the following changes and improvements:

Known issues

The images for the Lumia 950 and Lumia 950 XL have the following known issues, some of which may be due to Windows 10 or Windows 10X itself.

• Under certain circumstances, the Lumia 950 (”Talkman”) may fail to reboot properly. Shut down the device via other means (Developer Menu / Flash App & THOR2). This happens during Setup, where the device will display a black screen
• Cameras are not available
• Windows Hello Iris Scanner is not available
• Hyper-V is not available
• SD Card Boot is not available
• Battery life is degraded
• GPS stack is not using any sensor for navigation
• Miracast is not functional with many wireless devices, but works fine on Xbox, and Windows 10 computers
• Graphical glitches can be observed with acrylic effects on builds lower or equal than 20100
• Graphical glitches can be observed on shadows
• MTP may fail to start if the device is plugged a second time, stop the NcsdService to fix the issue via task manager
• Dual SIM devices are unsupported for Cellular, do not expect cellular to work properly on these
• DirectX is unavailable for x86 and amd64 applications
• Microphone level under Settings is stuck at 50%
• Phone may not boot reliably or have random reboots when the battery falls below 50% on certain devices, if all cores are enabled.
  As a workaround, you can run “bcdedit /set numproc 4” to disable the second core cluster
• No VoLTE
• No VoWiFi
• No Cellular data sharing
• Phone Calls require manual provisioning by the user on builds higher than 18908
• Text messages are unavailable on builds higher then 18908
• Some users might end up being unable to send texts on build 18908 and lower. To address this issue, open regedit on
  the device, go to HKLM\SOFTWARE\Microsoft\Messaging\IMEISpecific (or IMSISpecific), right click, go to security
  Tap advanced, tap change owner, in the dialog that opens, enter “Everyone” (without the quotes), tap check names
  press ok, press ok. Tap ALL APPLICATION PACKAGES, select ‘full control’, do the same for other listed accounts (optionally)
  Apply, and close regedit.
• An APN might be required to specify for some users in order to get cellular data working.
• Cellular is unavailable on builds lower than 17672.
• Some drivers and mainly sensors will not be working on RS3 (16299).
• Current issues with glance screen:

When the glance screen times out after the time specified there’s a chance the screen won’t turn off, this is still needing investigation but the issue can only be two things:
— either the device got out of S0ix and is sleeping at a lower level, because wifi is not connected for example, as a result the glance service is unable to take actions, this is a problem
— or, the glance service is trying to clear the screen, (there’s a specific panel driver command to do so), and for some reason this is failing.
This specific issue might take some time to completely iron out.

The following status notifications are not implemented in the port/non functional in the wrapper libraries:
— Battery saver indication
— Ringer indication (vibrate on, silence on)
— Alarm indication
— Detailed text indication
— Notification badges

The following functionality is not implemented:
— Wake glance on single tap

Hardware specific defects

• A considerable amount of Lumia 950 and Lumia 950 XL devices do not work with the HP lapdock properly when using a wired connection
