Default Stopping the OEM installation - possible ?

Hi,
i remember, that it is possible to stop the installation of OEM (after hardware booting).
I play with it, but only reset doesn't work.
Do somebody have an idea ?
for what ?
i want to get a german new TF3D version from the last offical version - maybe the newest version of ROMS have a TF3D where the calendar is working.
