When i try to do an update with Nrfutils Under android i get a REMOTE_DFU_OPERATION_FAILED since i added signing.
I created my pem file key with nrfutil.exe keys i copied Qx and Qy in my dfu_init_template_signing.c i modified Makefile to use dfu_init_template_signing.c instead of dfu_init_template.c i signed my update with my pem file key
