The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses. Only one SPI device can be connected to the FLASH pins and the chips select for the TFT must be on pin D3 (GPIO0)...
Check the chip is receiving 3.3V from a stable power source (see Insufficient Power for more details.) Check that all pins are connected as described in Entering the bootloader. Check the voltages at each pin with a multimeter, "high" pins should be close to 3.3V and "low" pins should ...
