JimKnopf:
First of all, test if there is any shorted circuit. If not, make a backup from the existing eprom. Flash the file from the wetransfer link i provided via msg.

@JimKnopf Hope this message finds you well. I was wondering if you might be able to help me out by providing the firmware/dump file that you have.

I was trying to perform an update to the latest firmware and in that process I bricked my amplifier.

 I am very familiar with the circuitry inside as I've repaired a couple of these, but never a firmware Issue.

Here's the strange thing I could power up the amplifier the ethernet lights come on, and I could connect to it

with the Texas instrument software via ethernet and load the firmware again it will get to 100% but the amplifier will never reboot.

I followed the instructions in the update PDF where it specifies to use a specific Mac address not the one from the Amplifier. I followed all the instructions to the tea.

But still no go.
