Jailbreak Windows Rt 8.1 Surface
The breakthrough came from security researchers netham45 and the team at the Windows RT Jailbreak Project . They discovered that by performing a specific sequence of shutdowns, reboots, and touching a specific UEFI variable, you can force the system to allow unsigned code until the next full power cycle.

For the most advanced users, there is an exploit that targets the Tegra 3 bootloader itself, known as the "Golden Keys" method. This is required for the most permanent modifications, like installing a custom bootloader to run Linux or Windows 10 on ARM.
To understand the jailbreak, you must first understand the lock. Windows RT 8.1 is structurally identical to standard Windows 8.1, save for one massive difference: it runs on ARM architecture rather than standard Intel or AMD x86/x64 processors. jailbreak windows rt 8.1 surface
