Logic board in need of repair

[tech19181]

I used Find My Mac, but for some reason the code didn't lock my mac until iCloud beta 4 and Lion GM. I didn't know what it was. I entered tons of passcodes that I thought I would have made it, but none worked. I feel like I entered the right password, but just like the person below (see quote), It won't accept it.

I tried the remote lock feature this morning, and it didn't turn well...
I typed in my passcode, but it keeps telling me "Wrong Passcode"
Then I tried to reinstall Lion, but I was LOCKED even after I repartition and format the disk!!!
Now I have no idea what to do...

Additionally, I had a firmware password on it. The problem is because of the firmware password I COULDN'T boot from a DVD, reset the PRAM/NVRAM, or anything else. The two locks worked together from preventing me from booting any source except the locked drive. Even when I correctly entered the firmware password and selected my boot medium, it would revert back to the locked screen.

I took it to the Genius Bar (even though Find My Mac hasn't "officially" been released). After waiting for an hour and a half, they pulled out the hard drive, formatted it, reinstalled lion, tried to reset the Firmware password by changing the RAM. Nothing worked. Now, they're replacing the entire logic board. Good thing it's under warranty, because it's $530 to replace. This will take nearly a week.

The said Apple Engineering will look at the issue, but hopefully in the future firmware passwords and Find My Mac won't permanently lock Macs. Just make sure you don't establish a firmware password. Then you can always reset the PRAM/NVRAM if you get locked out.

I have the same problem, I wish I had seen this before I tried the Lock feature. I set up password 1234 when doing it, but I don't know why my mac keeps asking me for a 6 digit password. I tried all sorts of password I could have set up, but none work. Additionally, I also have a firmware password (which I remember), but I can't do anything at all on my mac, including installing other operating systems or other versions of Mac OS. I guess I'm gonna have to take it for apple to take a look, and I hope they don't charge me anything.
