Hi.. confused on 7 times... I tried factory rest.. but its 6 times including the first time or 6 times not including the first time:
When it starts the blinking pattern just count 6 blinks and immediately remove the USB-c port from the charging port.
Repeat this power cycle 6 times: (Connect the cable > Blue light turns ON > 6 blinks > disconnect de cable)
At seventh time, connect the cable and leave it alone. The blue light will start to blink and the factory reset will begin. I put on the battery but the light stopped blinking immediately so I assume it didnt factory reset?
