Activation ACF

Found in the System Flash on offset 0x1C9080 and only present on Dev / Test Dumps.

Total length = 0x68 ~= 104 bytes.

There is a structure in it. It hase a Magic of 4 bytes, then there are constant 4 bytes following by unique changing 16 bytes. Then again constant 4 bytes following by unique 8 bytes and a third time, constant 4 bytes following by unique 64 bytes.

Structure and constant bytes are for every Dev / Test the same. Example:

Magic Bytes == Red.

Constant Bytes == Blue.

Unique Bytes == Green.
