SurfaceHub Gen1 Secure Boot Violation - Unable to Access UEFI Settings
Hi Microsoft Tech Community, We have 3x Surface Hub Gen1 devices showing "secure boot violation invalid signature detected" errors that appeared recently. Issue: Unable to access UEFI settings using the standard volume up + power button method across all affected devices. Attempted Solution: Followed flamurK's solution from 23rd June 2025 to collect Manufacturing.bin files using FAT32 USB drive named "BOOTME". Files collected successfully from all 3 devices. Problem: The secure file transfer link provided in that solution is organisation-specific and inaccessible to us. Request: We need a new secure upload link to submit our Manufacturing.bin files and device serial numbers for the 3 affected Surface Hub Gen1 units. Could Microsoft please provide an appropriate upload link for our organisation? Many thanks.29Views0likes1Comment
