I thought the chip had pins to lift up, not underneath (bottom mount?). I then tried removing the chip to re-flash but got board too hot and all the other pieces came off.

What is the yellow circle on the ESP8266 chip schematics? (link above) Is it representing pin 1?

Have you tried 74880 baud - some firmware gives boot information at this speed apparently?
