Pinebook64 Pro doesn't power on

[andrea_from_italy]

Hi friends,
I decided to install manjaro xfce on my Pinebook,and after a quick review of websites and wiki pages,I have realized that the device boots surely from a SD,maybe 
there are different procedures,but the straightforward one is the SD...But how can I write the image to MMC? I tried to write the image from an USB drive to MMC using dd from a live OS brought through the SD...Something has gone wrong and my device can't power on...I love this device and the underlying idea,can someone please give me an hint?...

Couple of questions that might help shed some light and help other members narrow down how to get your PBP back up and running:

What was the command you used to write the img from the sd file storage to the emmc?
did you unzip/tarball the img?
if you put your live os sd back into the PBP does it boot to the live os?
when you try to power on the PBP do you see any of the lights? (should at least see the red LED)

If, perhaps, you used an image for pinebook vrs pinebookPRO,
then this is expected (these devices have different cpus and different uboots)
Try a long press, press/hold pwr button +20 s, then regular 1s press
If uboot has been written to emmc you will have to remove/disable the emmc
This has happened to me, 2y ago or so

I am assuming that you get NO leds except charge?
