Does anyone know why one is not supposed to reflash the eMMC to a non pre production device? What exactly are the possible issues that might appear or is this only a warning to normal users as it will completely wipe the device? I used an n800 for 2 years now and reflashed it tons of times, so I just want to know if there is a way to reset a device to the shipping state without risk or if there are possible (technical) implications?
