I suspect you are going to put forth a great deal of effort only to end up with a very fragile communications path.

This is how I would approach the problem...

• Designate an EEPROM location as a "lock" (referred to as "lock byte").  If the lock byte is 0xC5 then the board is "unlocked" and an upload can proceed.  If the lock byte is anything else then an upload cannot proceed.

• The bootloader only needs a very minor modification.  Check the lock byte for 0xC5.  If the lock byte is not 0xC5 jump to the application.  The modification is so minor you may even be able to keep the bootloader image under 512 bytes.

• Once the new bootloader is installed the lock byte is now entirely in your hands.  You can make the process of locking / unlocking as simple or as complicated as you want.  For example, the user could enter a password via a terminal (like Serial Monitor) to unlock the board.  If the password is invalid, the board is locked.

Does this process have to be followed for a different core?

Wouldn't hurt.

There are a few options in the board menu for ATTINY85 and I'm not quite sure which one to go with.

Probably won't make much difference other than do not use the "external crystal" option.

The one thing I did was change the internal clock to 8 MHz so I went with the 8MHz option with internal oscillator and BOD disabled.

Did you execute Tools / Burn Bootloader after changing the board selection?

The issue I am having is that the blue channel doesn't PWM at all. After everything goes dark after the green fade, there's a split second pause and then blue turns on for a short period and goes off...It doesn't alter the brightness at all. Can someone point me in the right direction?

Use this core...

PWM is supported on digital pins 0, 1, and 4.
