After connecting to the computer, the radio is visible in the device manager, but the factory CPS does not see it. CPS OpenGD77 obviously sees the radio. In this situation, it is not possible to upload the factory firmware. When asked about the possibility of returning to the factory F/W, the seller stated that the technicians confirmed that this was not possible. I think somewhere on the forum Roger confirmed that for this change you need an old backup uploaded before the change to OpenGD77. I also don't see a way to make this backward movement from F/W to the factory version.

The size of the bin file is 16384KB. Now without replacing this file the radio is useless. I had such a situation with the RD-5R radio, in which it was damaged after performing a hard reset. Only after uploading the contents of such memory from a functional radio to the flash memory, it was possible to start it. Maybe someone has the ability to copy the content from their DM-1701, I would be very grateful, because I can't find the right file for a long time.
We do not have any code to write to the secure store where the calibration data is stored
Did you backup the calibration data using the official CPS
