My headset calibration went haywire mid-session last night

I've been using a basic consumer EEG headset for concentration tracking while I work on engine builds in my shop. The popular opinion in this community is that open-source firmware updates are always better than stock because you get more raw data. Well, I tried a third-party calibration tool about 3 weeks ago and it messed up my signal thresholds so bad that my focus scores were reading 95% while I was literally taking a nap on my creeper after lunch. The noise filtering went sideways and it started picking up every single blink and jaw clench as brain activity. I spent like 2 hours last night trying to flash back to the stock firmware but the recovery mode wouldn't even trigger. Finally I just unplugged everything, let the battery drain overnight, and this morning it booted up normal. Has anyone else had a custom firmware update ruin their baseline readings like this?

Wait, so you let it fully die and it fixed itself? That's wild but honestly makes me wonder if the third party tool was writing something into volatile memory that didn't stick after a full power cycle. Did you check what firmware version it showed after it came back up, or did you just start using it again? I've been holding off on those custom calibrations because I keep hearing about people's alpha/beta ratios getting completely inverted after updates. Like one guy said his headset started reporting deep focus while he was literally chewing gum and scrolling memes. Was your fake 95% score happening with the same baseline they recommended in the calibration tool's guide or did you mess with the thresholds yourself?

My buddy Dave once bricked his router by using some sketchy config tool from a forum, left it unplugged for three days cause he forgot about it, and when he plugged it back in the thing booted up like nothing ever happened. The firmware version was still the same old one he had before, so it was probably some temporary garbage that got wiped when the caps drained all the way. I wouldn't trust those third party baselines either though, I messed with my headset's thresholds once and ended up getting "alertness spikes" every time I sneezed.
