Fanoush's flasher from the device still requires redpill mode, sudo/su access, and a mess of steps that would still require a level of UNIX experience not found in most Windows users (sorry, guys).
In short, if your Mom had a N800 and wanted to rotate her screen and only had Windows, what would you do? If an N800 still requires you to be tech support and hold her hand, or for her to send her device to you to do and send back, it's not there yet and that's not a real answer. Any help? Any ideas? Care to be a god in many Windows users' eyes and write a step-by-step for the Windows folken?
