Hi,
A typical reason for getting invalid object error is that the DFU image was not signed with the correct key. Can you confirm that the bootloader was built with your public key, and that the DFU image was signed with the corresponding private key?
If the above is not the issue, can you elaborate on the issue? Also, can you upload the log from the DFU master?
sir sorry... where i can get log. im new to this field

Hi,
That depends on which tool you are using to do DFU and on which platform. What do you use (nRF Connect for iOS or Android, nRF Toolbox for iOS or Android, nRF Connect for desktop)? But generally it is possible to open a log. You may also get more information by looking at the RTT log from the bootloader if using a debug bootloader (example project with a name ending with ("_debug"), but that might be a tight fit on the small flash of the nRF52810.
I see. Most likely that means that pre-validation failed for some reason. Typical reasons include:
