Hello guys, these steps were very helpfull to me then I wanna share that with you u all!
How to set your Blu Ray Samsung D5300 to become "Region Free":
1. Eject the disk.
2. Power Off.
3. Power On.
4. Press STOP ( Remote Control AK59-00113A)
5. Press 76884 (This is the Code if you bought your Blu-Ray in South America - Region 4)
6. Will appear 4, On the corner up-right
7. Press 9 (That code means Region Free)
8. Will appear 9 (Without Code)
9. Watch Your favorites DVDs... hurray!!!!
That works!!!
If your Blu-Ray is not from South-America Region, replace the step 5, for one of these codes below:
1 – 2 9 3 3 4 (US)
2 – 5 7 5 3 8 (Europe)
