Can't Manually Enter Bootloader Mode

I have a ESP32-DEKITC-32E board that I'm trying to program with Arduino.
I can successfully program the board if I use a USB to Serial adapter when I hook up RTS to the enable and DTS to GPIO0.
However I would like to be able to program it without RTS and DTS. I would do this by the method I have seen everywhere:
-Start programming
-hold Enable LOW, hold GPIO0 LOW
-allow Enable to go HIGH
-within 100-200ms, let GPIO0 go HIGH
GPIO2 is strapped LOW too.
When I try this with Arduino, it times out waiting for packet header.
I don't see any reason why this isn't working. Does anyone have an idea why this isn't working for me?
