I have try to upgrade the RouterOS from vers 4.5 to 4.12 with the combinate package from the file option with WinBox: the name of the file is: “routeros-mipsbe-4.12.npk”

At the restart the RB not beep. I have connect the serial port and the message is:


RouterBOOT booter 2.23

Press any key within 2 seconds to enter setup..
