It's very easy to go into the recovery mode of NEO U1. 1.) U1 is at OFF state with a power adapter attached. 2.) U1 is attached to a display. 3.) Press and hold the power button for 6 seconds to go into recovery mode. 4.) Done. This is a mode that you need when wiping data / cache partition, and to update the box via USB .zip package method.
