This package allows you to install (or uninstall) the 'Golden Keys' unlock on a Windows RT device using only a USB drive. You do not need a Windows installation.
The 'Golden Keys' unlock (CVE-2016-3287 / CVE-2016-3320) discovered by @never_released allows bypassing the SecureBoot mechanism which prevents loading code not signed by Microsoft. You can read more about it in GOLDENKEYS.MD.
I put this together because the commonly distributed Golden Key unlock is in the form of a batch script which adds SecureBootDebug.efi to your main drive BCD so that it is ran when you reboot. This is perhaps convenient for average users but annoying if you do not have a working Windows installation. An uninstall option for undoing the unlock is often also excluded.
To use this tool just extract contents to a FAT32 formatted USB drive. RT devices are not fussy about booting from a USB so there is no need to mark it as bootable and it doesn't matter whether you're using GPT or MBR partition tables. From here the procedure for booting from a USB is specific to your device model so you may need to look this up yourself.
Below are known instructions for common models to boot off USB.
- Press and hold the Power and Volume Down button.
- When the Surface logo appears, release these buttons.
- Press and hold the Windows (bezel) and Volume Up button.
- When a white cursor is displayed on top left of screen, release these buttons.
