So I’m not sure what happened but after wracking my brain and searching any and every topic on the internet and getting no results I tried Updater one more time with nothing showing as usual. My cousin was helping out and just started pressing random buttons because we were hopeless at this point and all the sudden it popped up in Updater and let me finish the update! By some miracle my unit is now in perfect working condition without any loss to presets. Thanks for the help anyway!

So I just tried to update the firmware on my Helix LT to 3.0, I believe it was 2.92 or something before. The first time I tried it the update failed, it said to turn the Helix off and back on again and try again. The second time it again failed, but this time when I started the Helix it failed to boot and now is stuck on the screen that says "Boot Failure, Entered Update Mode!" (something that doesn't seem fit to have an exclamation point at the end imo :D) The Helix is no longer recognized by HX Edit. I have tried different USB cables, tried moving from my Mac to a Windows 10 machine, tried installing multiple versions of HX Edit on both devices, nothing is working. I'm starting to stress a little because I need the unit to play this Sunday and could really use some advice other than change the USB cable or wait 10 hours :)

I've tried the ground lift, neither positions change the squeal, and it doesn't matter whether there is a guitar plugged in or not, or if the helix is on or not, it squeals whenever the helix is plugged in. It should make sense then that the volume knob and presets also do nothing to help, it is the same regardless. I haven't tried configuring the MP3 input to be a loop, as INSIDER isn't supported on Mac OS Catalina, however I will try installing it on our Windows 10 PC and try that. For at home practice mono output is fine, you can barely hear a difference between mono and stereo through the little amp :D Thanks!

I have a Helix LT that I plug into a Blackstar ID 100 V2 (a digital amp that I use for practicing at home). The Blackstar has an audio jack input that bypasses the amp and goes straight to the speaker, so I have the 1/4" phones converted to 1/8" and run into that. I'm not sure when it started, maybe a few months ago, but there has been a constant, high pitch squealing coming from the speakers. The only thing that makes it go away is either completing unplugging the amp from the helix or unplugging the helix. It does not matter whether the helix is powered on or not, or what outlet either of them is plugged in to (I have tried plugging them into the same wall socket, same power strip, different sockets, extension cords to different parts of the house, you get the idea). I'm also sure it is not a cable problem, as I have tried many different cables, in addition to left or right 1/4" output from the helix, and going straight into the Blackstar 1/4" which runs through the amp. My cousin has a Pod HD, which when set up in the same fashion as the helix has no squealing at all. I also tried running the output into a mini portable everyday use speaker, and had no squealing there. I'm rather new to guitar affects systems, and electric guitar in general I guess, so I'm not sure where to start or what the cause of the problem is. Any suggestions and feedback is much welcomed, thanks :)
