No, it does not. Or there are at least other way to get the pattern and I do not understand how you can know that being unable to read the firmware can cause the checkerboard pattern since there is no way to confirm that the firmware cannot be read (the files in the system folder is not the firmware).
You get the checkerboard pattern if the system folder cannot be read or if the disk were the system folder is placed cannot be read.
