2nd Half of Bypass Programming Fails, Can't Get Yellow Light

2016 Mazda CX-5 Automatic Pust-Start
Stand Alone 2 Key Programming
Guide 62951

Had trouble at first getting through the first round of programming (steps 1-12) as I was failing to get the yellow light to illuminate. Got some help from some other answers and finally succeeded by removing batteries from remotes, keeping one in far back seat while programming the other, and performing steps quickly. Made it through decryptor step successfully. I've run into trouble at step 17 (repeat steps 1-12), as I'm unable to get a yellow light despite a ton of attempts. I've tried ignoring my failure here and proceeding to try and start the car but it appears that the bypass was not successful, as the unit does try to start the car, but gives up after what looks like 2 attempts and fails with 3 flashes of the red light on the unit. The dash never activates and the security light continues to flash throughout the attempts to start.

I finally succeeded by downgrading to the minimum recommended firmware version (71.44), loading the suggested options, resetting the Evo-All and proceeding as per the manual.
