It seems some clones arround there can only load the blue profile, for me was stucked on that until I dumbly format the drive and copy a new set of files but the RCM loader never works again, even I did try to reflash the firmware but no luck, it never come back, contacted the seller and refused to change, amazon refund me. when I manage to contact RCMLoader support team, they inform me what my RCM was a cloned one and have no support.
I only was able to get a R4s which also only can inject a payload but in a extrange format, so I did opted to use ArgonNX,
https://github.com/Guillem96/argon-nx/releases. Is a payload which load any file named SD:/argon/payload.bin on your SD card, or can show a menu to select and load any .bin files on your SD:/argon/payloads/ folder. so you don't need to update your paylad on the injector only a file on your SD Card.
For me was:
Injector: ArgonNX
ArgonNX: auto load Hekate
Hekate: load atmosphere/package3
and only add 1 second of delay if I inject Atmosphére directly. with the plus of having Hekate & Nyx and for the next updates do not need to touch my injector.
