3 days in, slow/stuck or no boot.

Thank you for responses. Pinebook pro booted from emmc to start with for approx. 3 days, after I got it just over 2 months ago. After a Manjaro update, it then went to black screen and didn't boot at all. Then, put Tow-boot onto PBB and managed to boot into pmOS, but couldn't get it onto emmc. Received messages to the effect that card or emmc not recognised voltage select -110. After awhile, could only use USB sticks with pmOS, not SD cards. Unfortunately, zero'ed SPI flash which caused an inability to boot at all- black screen, only light is at red barrel port charging. Pressed power off 7-8 seconds (several times) as suggested. Unplugged battery and barrel charger several times to see if red power light would come on. Tried Tow-Boot, pmOS emmc (emmc area doesn't appear damaged), pmOS sd cards( yes, I have PBP images).Nothing works. It seems that PBP is e-waste, now. This is quite disheartening as I wanted to use it for some work as well as to learn more about such laptops and Linux in general.
