This was the trick for me. Had the exact same problem, and tried every reset in the book. Nada. But read this and realized i was holding down the switches too long. Tried again and.. voila! Thanks!

Just when you thought it was safe.. lol! :P

While I have to agree that it may be "convenient" to link to a BT device for control.. BT is sketchy. One thing I could imagine happening is that I'm in the middle of a set, reach over to my trusty BT device to make a set setup change, and <insert very loud tire screeching sound here>! Granted, wired solutions can (and do) have the same issue at times. But they are FAR more rare then BT solutions. Hey.. I'm all for convenience and "quickness" of access to setups. But tech is tech (and it's my full-time job for the last 20 years). Things fail - and the last thing you want to do is put yourself in the position of being subject to a weak technology process. Also, can see Line 6's perspective here. If they include it, pros (or semi-pros) will think they can rely on it. First time it fails during a set will cause a HUGE wave of bad publicity for the product... when, in fact, it's the base technology (BT) that is flakey by nature. Anyway.. just my .02

Had the same problem here. Here's the solution: - Go to the Line 6 site and download the appropriate drivers for the Amplifi device you own. Install them. - During that installation, you will be asked to plugin your device to USB (do not plug it in until asked) - Finish that install. - Start the Line 6 Updater and .. voila! Follow the on-screen instructions to update. A factory reset will be required. And you might as well unpair your bluetooth device because you'll need to re-pair it anyway after this is all done. Worked like a charm for me.
