I will give it a shot and connect CHIP_E to VCC.

No luck.
I had GPIO2, GPIO15 and GPIO0 all connected to GND, and CHIP_E connected to +3.3V.
Interestingly enough, if I leave CHIP_E connected to +3.3V and disconnect GPIO2, which normally boots the blinking program that I managed to upload once, I get a solid green light.

I can't find a CH_PD on the board schematics (https://goo.gl/NFMJ7b).
That is the chip enable signal, should be the CHIP_E in your schematic.
No luck.

Again, to load your code from uart into flash, on the gpio's you need exactly this:
GPIO15 = Low
GPIO0 = Low
GPIO2 = High (floating usually works too)
