Wow, that was really involved. The breakthrough seemed to be him seeing the through-hole via with the microscope where no branch in the circuit was supposed to exist. That is, after a whole bunch of dead-end exploratory exercises. Feels like the Pine folks should ship him a thank you package of goodies.
There was an OD4 diode, but it is deleted from the schematics.
this is why providing schematics alone is not sufficient. PinePhone only provides schematics and not board layout and it is entirely possible that they are only loosely related. an imperfect analogy would be providing source but only running a binary compiled by someone else. you can see what they intended to do, but not necessarily what they did.
