I've tried through the app oh my iphone and with the DJI Assistant. The download completes, get failed to update on the app and DJI Assistant.

Mark, please provide a screenshot of the firmware of the database for further check. Thanks for your support.

I did it no problem but I was using android.

I had this problem, are you connected via OTG? Mine failed 3 tries while connected with OTG, I tried it while connected via WiFi and it went first try. Not sure if this helps you, just passing on my results.

Please try to connect your spark with DJI Assistant 2 and update the precise Fly Safe Database to the latest one. Thanks for your support.
