Connect GPIO0 to GND, CH_PD to Vcc. Grab a 3.3V USB-TTL adapter, URXD to TX and UTXD to RX. Add a 3.3V power supply capable minimum 300mA to Vcc and GND.
Start the flsher. Set the appropriate COM port number, and memory size. Start flashing. Enjoy.
I don't know the memory size of the module, You have at least one at hand. Try 512k, 1M, 4M. One of them will work. Dont worry, flash mode can't kill your module, the boot part is in the ESP8266EX chip itself, so can't be overwritten this way.
