Difrnce DIT802 need firmware

Tablet Difrnce DIT8020 stuck on logo.
Mainboard: M805NC-MB.
CPU: Amlogic AML8726-MX
With the same mainboard are two tabs: Prestigio PMP5580C and Intenso 814. I tried to flash DIT8020 with PMP5580C firmware. Tab is starting normally with white screen and recognized by PC. Search for factory firmware DIT820 or Intenso 814 for flash via PC. Here are DIT8020 photos.
