(I have tried posting this in Music group's forum, but no responses so far. My gut feeling is there might be someone here with more clue about these matters than over there.)

I have a dcx2496 that seems to be bricked. I tried to update from fw 1.17 to 1.18, and got a file transfer error. I then tried to change the com port settings in Windows. Don't know which of these to faults that did the tirck, but now it's dead...

When I try to power it on the display lights up with the dcx2496 logo for a fraction of a second, same with the leds. Then all leds goes dark and display goes dark green; it is clearly powered on, but no function is available.

I HAVE tried to talk to the unit again over rs232, and i HAVE tried to do a reset as outlined here . Still dead.

Both the unit and the PC-sync worked as it should before my frackup.

Is there hope? Any not-publicaly-documented procedures I can try? I'm not afraid to open up the unit and e.g. do a reflash if anyone could tell me how... The unit is no longer under waranty. It is to cheap to be worth a trip to a certified service workshop.

The procedure as described via this link worked for me, though it would require an additional known working unit to accomplish. https://www.diyaudio.com/forums/digital-line-level/226523-un-brick-dcx2496.html

Alas, I don't have a workung unit.

One of the many pit-falls of computers.

If not already, you may want to try another key combination for a reset.  The manual references holding the "page" buttons and powering-on (which looks like you did).  There's probably another key combo available that may result in something different (good??  bad??). In my experience, there's usually more than one way to access a computers firmware/BIOS/PROM, whatever they may be using.

I just found somebody that appears to be selling eeprom chips for these, hope this isn't out of date and helps.. http://www.audioasylumtrader.com/ca/listing/Pro-Audio-Accessories/Behringer/DCX2496/EEPROM-UN-BRICK-FROM-BAD-FIRMWARE-FLASH/86352

In case someone comes here looking for the answer to this same problem:

It was all very simple. Holding down the input A button while powering up puts the unit in software flashing mode. Now the remote software sees the unit and is able to flash it.

Case closed.

Awesome.  Where/how did you find out how to do it?

IME may not always worked as described for some units. YMMV

Someone mentioned it in one of tje gazillion forums I trawled through:

https://www.google.com/amp/longview.be/amp/behringer-dcx2496-failed-update-recovery.html

Can't find any other documentation, and there seems to be an actual market for replacement eproms for this unit. Most of thise sellers reffers to failed fw update as a reason to buy their product... Glad I didn't have to.
