prophet xl not responding after os update from 2 to 2.2
« on: April 25, 2020, 03:19:24 AM »
just taken delivery of this so I decided to update the OS and followed the update procedure
all was fine, I did as it said when the update had finished ,and restarted,
now all I get is that black and white grain screen on the main and effects screen and nothing on the sample playback machine
any ideas anyone?
I have emailed support but it's a weekend :(

You’re going to have to manually load a SysEx version of the OS through the MIDI DIN input.

Are you setup to do that?

There's still a .syx file for the beta 2.1.3 in this post Prophet X BETA OS - v2.1.3. You could try using that SysEx file and then attempt the upgrade to 2.2.0.0, again. Instructions on using bootloader mode are in the second post of that thread.

I have the 2.2.0 SysEx file. If you want to private message me your e-mail, I can send it to you.

I've had to use it, and I've had to supply it to someone else under similar circumstances before too.
