Framaroot by XDA member alephzain claims to root many devices via a one click rooting app. The app allows you to choose from previously created root exploits. It is currently supported for OMAP 3, Exynos 4, Qualcomm, some Mediatek platforms and other devices. If you can't find a root method for your device then this app would be worth a shot.
