unable to flash bin file to NRF52 dev dongle

Hello! I am quite new to hardware design with these chips, I have been working with NRF24LUP1 for a while, and have custom bin file for it, not a hex file. and I am unable to flash it. any tips for me? I have a batch file and an exe that should flash it, which those work on NRF24 chips with a bin file, but for some reason I am unable to do so on NRF52 chips. even with a batch file set up the same way as I had successful on an NRF24 chip. so I am quite confused. I hope someone can help me soon. I tried this  tools to convert binary data file to hex compatible with nrfjprog but it was no help to me
