      Hello

       

      I just tried to downgrade my f/w and now my H90 will not display the boot screen. It will not get into recovery mode. Factory Reset does not work. The only lights that come on are the the line level indicators by the 1/4 jacks. Any help is acciated I have a gig tomorrow morning!!

      Sorry to see you’re having trouble.

      The good news is, the lights on the back are indicating that your H90 is OK; the update process for the internal firmware that controls the front panel probably got interrupted during the last downgrade; now, even though it looks like nothing is happening, it is doing the “fallback” version of the front panel update.

      Plug the H90 back in, and let it sit for ~5 minutes.  That should give the internal firmware enough time to program, and you should see the H90 display come back to life.
