That link suggests doing a Factory Reset to flash a kernel!!!
CheckROM RevoHD v4 is the name of a ROM and installation instructions are here on this page in the forum:-

Dark Knight is the name of a kernel that was at one time developed by
gokhanmoral from his
Siyah kernel and intended specifically for
CheckROM. However, this kernel was short lived and the last one was
Dark Knight v2.5.2, released 16th Dec:
Development on
Dark Knight appears to have halted and it no longer appears in the
CheckROM's,
Kitchen Pro. It has been replaced in favour of the
Siyah kernel. Once you have installed
CheckROM v4 you will see that you have the
Kitchen Pro installed in your App Drawer and could flash the
Siyah 2.6.12 kernel from there... I do not recommend this and would suggest you install it using this guide which includeds the correct way to install a kernel and also contains some settings that you might find useful:-

Both of the guides featured here are from the
very useful, "sticky", at the top of this forum, entitled:-
