since I can not update the system via the wireless network, I decided to download it from the official website and install it from the PC with the help of the manual. it all seems very clear, but the power on-volume up-volume down combination does not work for me. is this the download mode? the same used for odin? the guide says to press these three buttons, then says to hold down the two buttons until the software starts to download. Which two buttons do you refer to? are two or three buttons?
