I have the Verizon G4 and was able to get wake lock detector to work without root. Adb is required. I installed the drivers that were available when first plugging in the phone. Then enabled developer options and usb debugging and mock connections. Other than that you can follow the instructions linked to in the wake lock detector app page.
