Hi. heres what I did.. I installed palantine CFW and playing .cia games without problems.. but then I tried installing RXEMUNAND to play legit games.. the installation went well. launch RX emunand. make sure that im on RX.x.X firmware. went to settings. update with the latest firmware. at 99% my pocket wifi suddenly went down due to low battery. The update had an error saying update failed. Then it resets. But after resetting I was kicked, but what seems to be an updated interface, im guesssing its the 9.7 interface. because it has themes and everything.. then what I want to do is go back to my 4.2 SYSNAND. tried powering off. but when I power on my 3ds. I'm on that latest 9.7 interface. tried reformatting my 3ds but still on that 9.7 interface. tried accessing my settings. Im still on 4.2.0 system version. but on a 9.7 interface what happened? how to go back to my 4.2 interface?
