  • Don't I need to pulse on A15?

    No, Reset isn't connected on the Espruino WiFi, since you can do the same just by powering the device off with CH_PD.

    Could you try with a block size of 128 and a baud rate of 57600? It'll be really slow, but the slower it is the more reliable it should be.

    Your other option if that fails is to do:

    digitalWrite(A14,0); // power off
    digitalWrite(A13,0); // boot mode
    digitalWrite(A14,1); // power on
    digitalRead(A2);
    digitalRead(A3);
    

    and to then connect a USB-TTL adaptor directly to the ESP8266. It'll be a bit fiddly to solder, but if you use the high baud rates used for normal programming you could probably connect GND to the Espruino WiFi's pin and then just hold RX and TX on by hand.
