The UART mode is confusing for me atm so I wont go there .
If you want to flash the chip put VCC,CH_PD, and RESET high
Put GND,GPIO15 and GPIO0) Low
Don't connect any others at this point and turn the power off then on . You will get 1 flash only if the wiring is right . Then send the hex up to it Of that I am sure.
If you don't get 1 flash when it powers up you haven't got the FLASH mode which I assume is called that because you are transfering hex to the chips flash memory.
