Hi dblasco,

Actually I was wrong, the .bin file is OK. I can see it's advertising as RelayNordic after it's updated. So everything is fine on my side. Your .zip file is OK I can update the firmware with both Master Control Panel on PC and nRFConnect on Android. You may want to try again on your side.

I am using the example (with small modifications) dual_bank_ble_s130 that is activated with a magic byte in te application. Could this info help?

I generated the .zip file from the .hex (that is the .zip I sent you). You told me the binary image is not good. What happens then? Does the nRF5 goes back to the previous application? (that is what is happening to me, it is like if I had uploaded the same firmware)

Could you try to generate the .zip file from the .hex file ? How did you generate .bin file.

I tested your .zip here the DFU process finished normally (no CRC issue) but the binary image is not good, the application didn't run.

I also use nrfutil v0.3.0 it's for the legacy DFU. The newer version is for the secure DFU from SDK v12

Could you provide me with nrfutil.exe last version? The version I am using is 0.3.0 (.exe that comes with Master Control Panel). I tried to install newer versions but it is not working well, maybe using the .exe is easier.

I edited the question including the .zip file. I hope it helps.

Yes, it's a CRC error. Could you post how you generate the .zip file? Or maybe post the .zip file here. If you don't want to post your application hex, you can test with one of our example project.

I checked the log in the smartphone, and the error is REMOTE DFU INVALID CRC ERROR

I have also followed your advice and put --sd-req 0xFFFE and generate directly from .hex with no success

I edited my question with the log you asked. I only copied the last part of the log, because it is extremely long (I think I include the error). If you need more parts of the log, please ask me.

Please provide the log when you do DFU with Master Control Panel (File -> Log File)

You can use --sd-req 0xfffe to avoid softdevice check. You don't have to convert hex to bin, please simply use the .hex file you got after compiling when you call nrfjprog.
