As to the dev system, I had to go to seminars to learn more but we canceled our Smart TV plans so I think you'll have a long haul to get this working.
Why not used a PC for now?
Hey all,
I recently bought a Samsung UA40J5200 Full HD Smart TV.
I found out that the Samsung App Center doesn't support our local "Netflix-like" program (Cellcom-TV App).
Turns out you can install Cellcom TV only on LG Smart TVs.
You can install the Cellcom-TV on your mobile phone (its on Google Play)
However I understood that there is a way to transfer the app from your pc to the tv and install it there as a Samsung Programmer.
Have anyone had any experience with this kind of programming or made those adjustments?
Maybe can lead me to releavent guides?
I found this post: https://www.cnet.com/forums/discussions/how-do-you-install-non-samsung-apps-on-samsung-40-smart-tv-635258/ and opened a samsung developer account, but cannot follow up as I couldn't find the guide.
Any help would be appriciated.
Thanks in advance... Oren.
