You might have a corrupt preset.My brand new one just did it again, turned it in and scrolled to a preset, then frozen switches and screens.
You might have a corrupt preset.
If that can help: My FM3 froze few times at some point when I was scrolling between presets.
In the end the problem was that there was one extremely heavy CPU preset in the lot that was not “sustainable” for the FM3. So each time I was ending up loading that preset, even if it was just extremely quick while scrolling to another preset, it was making weird things.
Making sure to avoid that preset (it was the kitchen sink preset from Yek) solved the issue. I ended up deleting that preset and no issues since.
Pretty reproducible hang here if I enable the new tuner mode in 302, as documented.
I wish someone would confirm this is a bug, and, that Its not hardware.
