Yes grob is closed but at the other thread one user managed to change the hex values to show the UA of Android 4.0.1.

For pr1.2, do the following:
make a copy of the original grob to MyDocs.

run opensh in terminal after following the steps in inception thread.
replace the original grob with the modified grob.
after a reboot u need to copy back the original grob before replacing it again with the modified grob.
