The automatic update of TCL 65R625 failed and error 004 was reported. The original system was 12.0.0, so I restored the factory settings. When activating the TV, it will automatically update the latest system. Then the update system reported an error, resulting in the current TV being unable to be activated. I used USB to update the system, but it was prompted that the file failed to open and needed to be retried. Changing the USB and formatting FAT32, NTFS, etc. could not be updated. Please give me a solution. If I cannot update to the latest system, can I activate the TV separately?
