This is D series TV based on C series firmware or so. We know few models which run on VAL* firmwares. What exact firmware it has on board? T-VALAUSC or T-VALDEUC? i guess you made typo and on LN models should be T-VALAUSC.
The LN40D630 does not support Samsung apps, so should I even bother with SamyGO on this tv? or would I be able to install apps on this tv after rooting with SamyGO ?
