Thank you :-) And thanks for your input.

The phone still seems to work after reassembling ;-)
I did a quick, temporary, low-effort test on DCIN... I split open a USB cable and taped the 5 V and ground wires to the bottom-left and bottom-right pogo pins. The other end is USB A, which I plugged into a power brick.
Ta da! It charges, just like you'd expect to happen if you plugged into USB C. So far, it hasn't caught on fire ;-)

Yes, I would like to. We should be careful not to publish information that could damage others' phones, so I will probably wait for a bit more testing and/or confirmation from others. So far I think we got it right though!
Anyone else interested in taking a "risk" and charging your phone via pogo pins?

And of course I would prefer if someone from the Pine64 team would confirm what they intended in their design.

Yeah. I'm still curious why they are named "DCIN" and "DCIN ", but we'll probably never know. Maybe the hardware designer had to work around something. Maybe it means something, I don't know.

I started another thread, covering this... but no answer so far.
It should be open as they claim
Totally agree! Fortunately, the limited/outdated info didn't prevent me from figuring this one out. But we should still have access to the info, since this is an "open" hardware project where the community develops the software.
