After flashing new firmware it is mandatory to remove the 3.3V jumper if installed.If not when starting the module and micro you may fry them as 5V is supplied directly on the RF module and micro.Extreme care ,do not flash with 5V setting on USB-SERIAL and 3.3V jumper attached.If in doubt measure the serial device output with a multimeter.
###Method 2.
Uploading new firmware with TX switched on.
For this method DON'T TOUCH THE 3.3V JUMPER(NO JUMPER)!!!
This method is less prone to mistakes.The module is inside the TX bay.Move/set the jumper on BOOT0.
