You don't need to read the firmware to detect it's modified.
You send the drive a challenge, and it responds in a way that an original firmware wouldn't.
You don't need to read a firmware to detect it's modified...they've banned countless times before.
Fact is, nobody knows, and I choose to believe the opinion of the person who has created all the firmwares over someone on an auto forum.
If they could read the firmware, he wouldn't be working on a new firmware. Changing a single byte will cause a hashcheck to fail, and if they were reading the firmwares they'd be able to detect any change, and thus it'd be pointless for him to make a new one.
What do you mean about c4? He's always told where he fucked up or how they caught people using his firmwares. You using his firmware is your own risk, why should he care if you get upset?
