DVDROM Keeps ejecting!!

[bunghoolio]

After getting the key from the Liteon drive successfully, creating spoofed FW, flashed TS28, tried putting TS28 DVDROM in the X360 it does funky auto eject. You can open and close the tray with eject button, but when the tray closes, it only stays closed for 5 secs, then ejects. Even when a disc is present. This started to happen after I grabbed DVDKEY. I have grabbed many DVDKEY b4. What have I done wrong on this occasion to cause X360 Mainboard to keep eject ANY DVDROM I try to install on it? It is not a prob with the Liteon DVDROM or TS28 DVDROM as it tested in another X360. Any help appreciated.
