In the pc world I like the saying if it isn't broke don't fix it.
Please explain in full detail exactly what you did and what happened and are you referring to the MEI driver?
Check out the motherboard manual and find out where the Cmos jumper is positioned. there will be 3 tiny pins and Jumper will sat on pins 1 & 2. Power off the computer and unplug it from the wall. Press the power button to completely discharge the system then move the Jumper from pins 1 & 2 to pins 2 & 3. Wait for one minute then move the jumper back to pins 1 & 2. This is the most reliable way to clear the Cmos and if you're still getting the 00 code it's RMA or recycle time I'm afraid.
Have you tried clearing the cmos with the button on the back? Power down your pc before doing so.
