Just close to January 1st I bought this TV to find out a way to extract the encrypted and signed key-file in order to unpack the signed and encrypted .epk which updates its firmware manually if you don't have internet access.
I have opened the back of the TV and took a closer look at the motherboard to find where the UART is located so I can connect to it.
JTAG for CPU is found, but I don't have the proper equipment to dump the EEPROM yet.
Yes, there is a Hackerspace nearby, but they don't have the proper equipment as well.
So, now all I need is to get the Service Manual to see schematics.
I found it on some site for Service Manuals, but it costs $25 and I don't even know if they're trustworthy.
Is there anyone that can assist me in finding the book or a PDF-version of it?
I already have the user manual so that's not needed.
