You will need root browser or root explorer but use root explorer it better then root browser
Open root explorer Go to System/usr/keylayout
In keylayout you have to find Sec_KEYPAD.KL
Long press on Sec_KEYPAD.KL select open it with text editor
now comes the complicated and risky is you open the window for editing and in the line where it says: KEY 102 HOME have to modify it and make it something like this: KEY 102 HOME WAKE_DROPPED
then save it then Reboot Your device then injoy.
