I got black blank screen after flashing with wm6.1 and activesync not connected my Apache 6700. Then I downgrade to WM5 AKU3 from Verizon.
I put my apache to bootloader mode, with press hold power button and note button with fingers and reset button with stylus, it show Serial on screen, plug usb cable then USB on screen. Run AKU3, Next it will upgrade to WM5.
It works for me.
