If the SD card was converted over to be "Internal" memory before you reset the device, then that card can no longer be read, by any device. It was encoded when it was made into "Internal" rather than "External" storage. Meaning no other devices could access it. Your phone, since it was reset, is viewed as a different device. You can try contacting the manufacturer, but as far as I know, the data on the card is now inaccessible.
