Hi all,
I had exactly the same problem and crashed my DM500HD upgrading to the latest beta.
i already fix it with dreamup.
Before flashing OpenPLI again to the last working beta version, i have downloaded the old flash contents from the boot GUI that returned a 60MB file called "FLASH".
Now i want to unpack it to access my old settings, do you know if there is anyway to open it?
Thank you for your help.
