can't Can't flash esp8266ESP8266-01 with sparkfun ftdiSparkfun FTDI basic - wrong direction/command

I am trying to flash an esp8266-01ESP8266-01 using a Sparkfun FTDI BasicSparkfun FTDI Basic. Above is my diagram,. I am using a 16v max in16v max in to 3.3v out3.3v out to handle the drop from my FTDI (5v5v) to the esp8266ESP8266 (3.3v3.3v). I am using a Logic Converterlogic converter to change the 5v to 3.3v for the rx/txRx/Tx. I have done this successfully (but with spotty results), flashing the esp8266ESP8266 with an arduino unoArduino Uno. Then I tried to reprogram the esp8266ESP8266 with my arduino unoArduino Uno and it kept giving me thean error that ends with:

So I decided to troubleshoot by seeing if the problem was with my unoUno, because it is fairly old - and I got and FTDI Basican FTDI Basic - with the basic I get a little further - the whole output when I try to upload is:

Can anyone explain this line in detail?:

Before, when flashing it with my unoUno, it would work well enough, this. This used to happen, and then I would unplug it and plug it in (reset) and try again, until it eventually worked. However, now it happens everytimeevery time. I have 4 different esp8266ESP8266 that are functional and they all respond the same way, with the error above. This leads me to believe that is something with the circuit, or with my settings -, which are:

I have tried messing with the spiffsSPIFFS (what are those? packet size?) as well as changing the CPU frequency to 160hz160 Hz, and I tried 80hz80 Hz for the flash frequency.

I used this same system to program the espESP before with an arduino unoArduino Uno and I was successful - why. Why is it so finicky, and what does the response with the 0x01 0x03 instead of 0x01 0x04 trying to say?

Before when flashing it with my uno would work well enough, this used to happen, and then I would unplug it and plug it in (reset) and try again, until it eventually worked. However, now it happens everytime. I have 4 different esp8266 that are functional and they all respond the same way, with the error above. This leads me to believe that is something with the circuit, or with my settings - which are:

Board - Generic ESP8266
Flash mode - DIO
Flash freq. - 40hz
CPU freq. - 80hz
Flash size - 1M(64k SPIFFS)
Debug Level - none
Upload Speed - 115200

I have tried messing with the spiffs (what are those? packet size?) as well as changing the CPU frequency to 160hz, and I tried 80hz for the flash frequency.

I used this same system to program the esp before with an arduino uno and I was successful - why is it so finicky, and what does the response with the 0x01 0x03 instead of 0x01 0x04 trying to say?
