this shows that the firmware is authentic

where is the actual code of the firmware?

did you read the code?

word for word?

did you understand the code when you read it?

did you verify the code of the firmware?

or do you TRUST the manufacurer and people who you do not even know who are security software developers, who would or maybe would not warn about malicious code in the firmware. when would they find out? days later or months later? if ever
