Hi, I was playing my Amplifi150 and everything was fine. I turned it off, turned it back on and I got 4 flashing lights so I googled it and found that there was a failed update. I have repeatedly tried updating it on my computer via USB as everything else on the amp is not working now. Any ideas on how to either hard factory reset or complete the install? It seems to install the firmware but the process after where it must clean things up is failing. I hope someone has experienced this and can share the fix.
