Hi All

Have a UE32J5600AK with firmware version 1520 - would like to downgrade if possible.

Could anyone recommend or advise if this is possible, did download HKMFDEUC to FAT32 Flash, but TV says no update available.

Thank You.

Ok I bought a UN65JS8500 (2015 model) and I love it. It's my first smart tv and I knew nothing about these firmware updates. I now have noticed that the 3D and overall performance of the tv Sucks since factory firmware has been upgraded from OTA updates. All I want to do is reset the firmware to what it was to when I first turned it on. The tv says its on v1530 as of today 2018/05/04. I now have auto update turned off. At one point last year, I thought someone hacked into it. Not even confident to have it connected to internet anymore. In the maintenance menu, should the screen type match the model/size? Mine does not. Its completely different.

I'm a pc tech but new to working on tv's. If I could get some guidance on how to just flash the Rom back to factory I would really appreciate it. The tv should store a master copy as a backup correct? Or do I have to download the version, I think it was 1401, don't quote me on that.
TIA.
