put back original bin into main bios and use RCUnlocker to the 2nd chipset which should be EC_ROM. At 1st boot reset security settings.

He's not resetting security at 1st start, this happened to me when I did unlock an HP and missed to enter in bios to reset security and laptop did boot from ssd. I had to put back both original bin files, start the laptop, let it boot, then reflash EC_ROM and reset security settings to default.

So, try this: put back original files, power on the laptop and see if security message is displayed. Then modify EC_ROM with RCUnlocker and reset security to defaults, it's at the end of security tab. Remove ssd to be sure laptop is not booting.
