Couple of possibilities here. Either they used different ir hardware in the otherwise nearly identical LTE version or there is something in the software that unlocks it. I'm hoping software. Can you name a couple of the apps that worked by name so that us V500 users can try them to verify if they work or not for us?(won't work ) Then I guess it's off down the road of stirring up some interest to pick apart the stock vk810 ROM to see what's up with this unlocked ir blaster. Thanks!
