hello suma!
firmware is ok, enter menu -> plugins, green button also. the list of softcams contains a lot, but no "mgcamdd_1.35a". i have a "mgcamd" under "settings -> ... -> softcam configuration -> select softcam (mgcamd, cccam or no). i dont know whitch version of newcamd is installed.
maybe your tutorial is old and not for "OpenPLi-3.0-beta-vusolo2-20130911_usb.zip" or V4?
greethings!
