try this..open the disc tray then hold the "info" button for several seconds til the info about the player shows up..tingnan mo kung ano coding nung unit mo..mine's region A for bds and region 3 for dvds..then after that do the trick posted above..di naman necessarily mabilis ang pag pindot basta tama lang ang sequence..i did the trick 3x before it worked..
before the hack i tried playing the ff dvds:
incubus: alive at red rocks (region free) - ok
american gangster (jack sparrow) - ok
transformers (region 1) - did not play*
spiderman 1 (region 1) - did not play*
* this image was shown when trying to play region 1 dvds
then after doing the trick/hack di na lumalabas yung image at napeplay na ang region 1s ko..pero sa info region A and region 3 pa rin ang nakalagay..try and try lang baka sakaling gumana. meron rin kasi akong nabasa sa interwebs na they did try the trick like 10x before nag work..
hopefully meron din trick para ma region free ang bds..
