Samsung HT-TX500 region free

Hi there
i live in Thailand and just made my HT-TX500 region free,
this is what i did

your dvd must be off with no dvd inside
push power on wait til no disc come up then push enter
then push 84269 then push enter then wait for the dvd to turn off
wait 5 mins.then push power on and that worked for me

Go to the forum of videohelp, and then go to the DVD hack section. You can check more solutions here:

If not, you can use Leawo Blu-ray Copy to remove the region code on the disc.
