Does the Bypass Firmware matter for DCryptor to work?

Question

I have a 2020 Toyota 86, and followed all of the programming procedures from the provided guide, but was on the incorrect firmware (I was using 84.xx instead of 79.xx). All the programming steps were successful and I finished with the red and yellow alternating lights.

After getting those lights, I unplugged the module to start the DCryptor process but got an error saying no data found. Could this be due to using the incorrect firmware? I am using an EVO-ONE.

Answer 1

Both those firmware will work on supported vehicles, the 79.xx firmware is a slightly older fw before Toyota and  Subaru were separated.
