Thank you so much sir! My Amplyfi 150 died on a party in August last year. I thought I have tried everything but the updater did not recognised the Amp and factory reset did not work.I had given all up on the box. Then when I checked the forum today after many month, I found your post, used the link to the driver, boot the box opp holding tone & tab button, and wow, the updater recognised the Amp, starting the update, and the old box is back in business. Using it mostly for Amplifying my Helix at home, or as music party box at the terrasse. Garden party tomorrow, and you saved my day. Thank you Thor, in Norway
