Safe Way of Disabling Driver Signature Enforcement
1) On Windows 7 bootup press F8 to get to the extended boot options screen
2) Choose "Disable Driver Signature Enforcement"
3) To start DosFlash right click on it in Windows Explorer and choose

SlimKey extraction failed!

Хотел прошить с заводской на LT+ 1.92.

Заранее спасибо за ответы! :(
