So I know DSiware injection can be used to install B9S. My main 3ds has B9S 1.2 installed. My coworker got a 3ds off craigslist and has 11.4. I told her that I can put the same thing on hers like mine but she is not near tech savvy at all. So it got me thinking that maybe if I was to do the old way of using menuhax. But I can't think of how that would be done. Is there any way possible to get to a lower FW 11.3 without having B9S in the firm installed? Any input is welcomed. And before I get answers that say why not B9S, its that she won't be by me everytime. Our job transfers to other locations and I wouldn't want to leave her with a non-working 3ds. She would most likely mess up updating B9S if a later FW requires updating the payload.
