Hacking [Help] update rxtools 3.0

[mitros]

Hi everyone.
This is my problem; I have my emunand on rxtools V2.6, and I want to update to rx 3.0; My sysnan firm is 6.x; I did everything in the tutorials, but it just won't work!
Maybe the problen is the firmware on my sysnand?
Any suggestion, besides the option to update my sys firmware to a 9.2?

I added all the files from the tutorial, and I did all steps, but when I have to read the QR code that send me to the internet browser, it kicks me back to the home menu; and the rxtools it never updates

I tried to do it many times, and i can't update it
