Thanks for all the replies.
Actually the problem was not the permissions, since I had tried the
read+write combination already.
The problem was the variable type of the "root" variable.
Here is the original declaration that I was using that caused the problem:
EFI_FILE_HANDLE root;
Here is the declaration that worked:
EFI_FILE_PROTOCOL root;
Thanks.
