Hello everyone, Apologies if I'm writing in the wrong forum, this is my first time. I've just bought a LG 55ur80006lj 4K UHD Smart TV, I've got an Amazon Firestick 4K that I'm using with it, when I go to 4K content, sometimes it shows UHD at bottom or sometimes 1080p HDR on it, when I go to settings it mentions, for 4K I require a stable strong internet (which I have) and an HDMI port supporting HDCP 2.2 I wanted to know if the model I have, does it support HDCP 2.2 or not!! Thank you

Hi guys First of all, I want to warn you that perhaps they read a lousy English, this is what came out of the Google XD translator, I do not speak English, but I hope they can understand me and give me their help. I have a LG 42LB6500-UM TV that apparently has a problem with the Firmware, since I bought it I had automatic updates configured, so it was updated several times until arriving at the mysterious Firmware 05.00.15. Why mysterious? Because according to the support page of LG this software is not in the compatible history with the model of my TV. Here the problem began. Since then I can not update the Firmware in any way, online it marks me an error "error in the decryption of the data ...", and when I try it for usb simply nothing happens. I'm stuck in version 05.00.15, but that's not the biggest problem. From that moment I can not access the content that HDCP requires, that is, netflix, cinepolis Klic, Prime Video, etc. Yes, it allows me to play YouTube. If I turn on the HDCP in the configuration of my PS4, the screen turns blue. An error in HDCP appears in the InStart menu. Can you think of an idea to solve this problem? Is it possible to delete the firmware and install a new one in a different way to the traditional one (online and usb)? I am 3 years old with this problem, and the LG technical support staff has only told me that I should change the Mainboard, that is very expensive, and the Mainboard of my TV is in excellent condition, it is a software problem. LG 42LB6500 Firmware: 05.00.15 Serial number: 406RMEN7R340 WebOs TV version: 1.4.0-2507 (afro-ashley) regards
