DFU Update says zip file not supported

rider

I'm trying to apply a firmware update using a zip file that has worked with older version of nRF Toolbox. Using the current version, (4.1.1) on iOS, I select DFU, then select my zip file under User Files. When I press Done, I get a popup saying "DFU -- Selected file is not supported".

Any ideas what to do? It's not my file, and I didn't have any development role, so I'm just trying to figure out how to apply the update.

Any help would be really appreciated.

The zip file: IRT_V2_REV_A1_C_1_0_39.zip

    I'm not sure about updating directly from the files, and I'm wary of bricking the device. I already downloaded the individual files, application.hex and application.dat. I can select the hex file, but do you know if it should be classified as a softdevice, bootloader or application? And what about the dat file? I assume it is important, so will that automatically be accessed if the hex file is successfully applied?

    Thanks!
