Hi guys, I need your help. Im trying to install rxtools 3.0 8b (to could make coldboot) but Im in rxtools 2.6. The thing is that I followed every step of some tutorials there in the net but, when Im in the part where the QR do the exploit thing, I cannot do it because Im in 4.4 sysnand. I tried to put the http dukesrg bla bla bla and it loads, but never work. Can anyone help me with this? Remember: Im on olds 3ds sysnand 4.4 and the QR feature its not on there. Thanks.
