I recently experience a lockup with my MT2496. Here's the short version: I had recorded the support act, stopped the recording, and the MT was hung "writing file" (the hourglass was frozen). With no way to reset the device I missed out recording the main act.
Had a quick search on here and I found this:

[192] My MT2496 sometimes locks up when I try to start or stop a recording. What's going on?
It appears the MT2496 is sensitive to its start-up and file-stop conditions. If the MT2496 is not receiving a live S/PDIF signal when powering up or stopping a recording, the MT2496 will sometimes freeze, i.e. lock up. The only resolution to the freeze seems to be a re-set (hold down the power button until it powers off, then start over again). Workaround: ensure your MT2496 is receiving a live S/PDIF signal before powering on or stopping a recording.
I was recording via the 1/4" inputs, NOT via s/pdif. Does anyone know whether the above faq entry would still apply? I can imagine how the MT could get confused if you were recording s/pdif and the signal went away... but that's not what I was doing.
A little more info on what I was doing. I was running dpa4060>mps6030>mt2496, phantom power switch set to 'off', l/m/h set to 'l'. I was recording the support act, hold switch was set to 'hold'. After the support act I decided to just stop the recording without powering off the device. This is different to what I normally do: normally I go hold->off, record->stop, wait for 'writing file', power->off. This evening I went hold->off, record->stop, hold->on WITHOUT waiting for 'writing file'. It was literally 3 quick presses of switches/buttons, took less than a second and I popped the gear back in my pocket and waited for the main act. Of course when I came to restart for main act, I found out the unit was locked-up (and of course house lights were down at this point...) Ended up waiting for the damn thing to power itself down overnight
Now I've tried to repeat what I did, try to make the damn thing lockup here at home... with no success. I'm wondering if this was a fluke? This was only my 6th outing with the MT.
I've read some other posts on here, people wrote to say they managed to get it to power-off by holding the power button for like 20+ seconds. Of course since I couldn't repeat the lockup I couldn't test this. I also read on some other website, someone had luck with power+del, but again, cannot confirm this.
So I thought I'd toss this out to y'all... anyone else expereinced a lockup? If so, how did you get round it?
(I'm running firmware 1.4.3 and bootload 1.02.)
Seriously considering hacking the device to put a reset button in... has anyone opened up their MT, and would be willing to walk me through opening the case?
Or maybe I should just go back to my trusty jb3... hmm...
Oh yeah, I'm using n 8Gb SanDisk Ultra II cf card, if that is relevant.
best regards,
stephen
Edit to add: one more note about the CF card. On this outing I had NOT formatted the card. On ALL previous outings I had formatted the card before hitting the venue.
Edit again: despite the unit being stuck 'writing file', after the device powered-down overnight, the recording of the support act WAS there, intact.
