Version 2212.12 (B)

This update addresses specific reliability issues present in version 2212.12. For a complete list of changes present in this update please refer to the version 2212.12 changelog.

This update must be paired with Surface Duo Drivers version 2212.12 (B).

NB: This update may not work on Surface Duo 2 currently. If you want to check out Duo 2 right now refer to the 2211.43 update paired with the 2211.43 Drivers.

NB: As always, in order to update you only need to run Driverupdater again as per changelog. You never need to reinstall Windows; Please make sure you use the latest driverupdater version (latest one released this week)

NB: If you still want to reinstall windows regardless of above notice, you only need to format the Windows partition again within mass storage as NTFS (and only this one) and then re-apply the wim file, and run driverupdater. Nothing else is required.

NB: As usual, observing graphical glitches during boot is both expected and normal currently, and only requires you to close the device and open it again (fold/unfold).

NB: Windows Setup is a delicate operation, please do not force reboot the device even if you think it is hanging, (especially if you see such graphical glitch, just get rid of it). If it feels like it's taking some time, just please patiently wait. A moving spinner is a happy spinner, do not force reboot the device or you'll end up with a broken windows installation anyway

Last NB: Some people may get a BSOD about the WMILIB.SYS driver (which is a Microsoft Windows Inbox Driver). While the root cause of this issue at the moment is not known, you may fix it by simply not having a cable plugged in, or, uninstalling the SurfaceBattery.inf driver using DISM (or using Driverupdater by simply removing such driver from the release zip beforehand)

[Pulled] Version 2212.12

NOTE: This Update has been pulled due to BSOD issues. A new update has been made available with some of the core issues fixed. Please use the newer version. (https://github.com/WOA-Project/SurfaceDuoPkg/releases/tag/2212.12b)

This update includes new features, bug fixes and improvements. Key changes include:

• Surface Duo 1: General ACPI Updates related to the recent driver update (v2212.12)
• Surface Duo 1: Resolves an issue where the right panel would be undervolted
• Surface Duo 2: Adds support for Engineering Validation devices with different Memory Bank Configuration
• Common: Fixes the previous workaround/issue with Memory Protection
• Common: Updated Project Mu

Full Changelog: 2211.43...2212.12

This update is compatible with every currently released Surface Duo 1 and Surface Duo 2 Models. Support for Engineering / Prototype devices cannot be guaranteed at the time.

Version 2211.43

This update includes new features, bug fixes and improvements. Key changes include:

• Surface Duo 1: Updated ACPI APIC Table in order to help fix a crash issue during sleep
• Surface Duo 2: Addresses an issue where the device would think the buttons are pressed and thus going to UEFI Settings or going to Universal Flashing Application if the user had pressed volume buttons before booting the UEFI using fastboot boot uefi.img
• Surface Duo 2: Removes a deprecated Errata patched in ntoskrnl.exe. If you were affected by a build throwing the following bugcheck: MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED, please update to a newer OS build.
• Common: Workarounds a new issue caused by Memory Protection code enablement in Project Mu
• Common: Refactored the way the repository makes use of binaries. The main reason behind this change is for better transparency as to where binaries come from, as well as reproducibility. This way you can, if you choose to, reproduce the binary repository very easily with your own firmware, and assert the origin of the binaries. A new tool was also released for this purpose, UEFIReader. This tool can also be useful for people willing to port their own device over more easily.
• New UEFI libraries were implemented, namely, user presence detection using side buttons, battery level checks to prevent booting into Windows if the battery level is too low to boot, or the error reporting storage library
• Common: Add a new Management menu for DFCI
• Common: Add generally missing DXEs commonly found on other Surface Devices, mainly Cryptography/Security dxes and Networking Dxes
• Common: Updated Project Mu
