My SA30 seems to be defective since yesterday. After powering on, it took \> 30 seconds to boot up and then I got a prompt in the display „Press MENU for Options“. Except a basic menu nothing works. ![image](https://global.discourse-cdn.com/free1/uploads/arcam/original/1X/712dee7aa0c279a5efdfe7533d3c4b5f12d97075.jpeg) What irritates me, the device no longer knows its serial number: „Serial Number Not Available” also MAC address is 000000… Is the Firmware broken? I have done nothing unusual, that could have caused it. I know, every IT user says that. 😉 Firmware is/was V867. At first I performed a system reset in the menu. Same problem occurs. Then I tried to install the latest firmware via USB through the menu. Since “Net Updating” did not disappear for over 30 minutes (!) on the display, I have now turned off the SA30. I read in this forum that you can re-flash the firmware by pressing the Service button on the back while powering on with inserted USB stick. I have not tried it yet, cause I don’t want to make things worth - if this is at all possible. Do I have to copy the latest swu file on the stick? It’s already on it. USB stick is formatted in FAT32. I just emailed the Arcam support. But due to the holidays I will not hear anything back till next week. Any help is highly appreciated. Thanks in advance. ---
