Zip archive with software for the X7 Alphabox receiver, version 185 dated 8 August 2018 according to the name. It is intended for updating the box or recovering it after corrupted software. Unpack it and load the image through the USB update procedure, or program the flash chip directly if the receiver no longer starts. Verify the model and main board before flashing, since boxes sold under the same name can use different hardware, and save the original firmware so you can roll back if the new version misbehaves.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @tvsoftwareworld. Enginerys does not host this file.
