I tried resetting it, but it still doesn't work.

Hello. Vestel 17mb185 motherboard. Damaged emmc KLM8G1GETF-B041 memory. The memory is not working, nothing is being read. I replaced the memory with a new one and reprogrammed the file from a Daewoo TV with the same screen, the TV started up, and I uploaded the original software provided by the manufacturer. Everything works, except CI PLUS, there is an error and the satellite module does not work. Can CI PLUS be repaired? In the service menu there is Update CI PLUS from USB, but where to get the file. Does anyone have any ideas? Is there a manufacturer update that will change the panel and keys...
