I screenshotted this from another thread, maybe worth a try:
• With the unit off (in your case, duh), hold the VOL- and the Quick Access Menu (AKA (…)) button down. Quick press the power button. • You should see the power LED blink a few times • It may take a minute or two, but you should see a boot after that
Glad I could pass on the help! Mine arrived today and has been smooth sailing but I was soaking up little bits of info like this on the lead up incase of any issues!
