Hacking R4 3ds delux card questions

[Chris G]

hi everyone

iv been reading for days since i got my R4 delux and some things i can't figure out

how can i back up my NAND?

how can i update firmware via the delux card itself. iv been trying to see if there is a firmware version similar to the gateway 1.0 where you can update via the cart itself but so far no answers just more questions

if someone can answer these i would appreciate it

1. you will need to use the gateway launcher.dat(or the old 3.0 R4 firmware ....dont use 3.1/3.2/3.3 they can brick your console), R4 disabled the gateway menu on their newest FW
2. you cant, r4's earliest release was a copy of gateway 1.2/1.1 so updates where already blocked
