ok the internet version so. I supposed you will have 4.4.0-10 if not it may be doesnt work.
*****THIS IS NOT THE NEWEST/best METHODE BUT ********************
for all this steps you dont need a gateway-card!
- Get the launcher.dat from the gateway (can't link it sry); get
rxtools;
- put your sd-card into a pc and copy the hole stuff to your computer as backup
- put the launcher.dat into your sd-card
- put the sd-card back into your 3ds
- start the 3ds and open the browser and go to the url go.gateway.com
- inside the gatewaymenu you can select format emunand.
- if you are there and done your formate, select backup sysnand (only for have it)
- hold d-pad down and b (it will shut down your 3ds)
- put the sd-card into your pc.
- move your nand.bin on a save place rename it well like nand_o3ds_<name>_<sn_of_your_3ds>.bin
- copy all the stuff you backuped in stell two back to your sd card
Congratulation big step one is done you have emunand.
big step two is following the first installation for rxtools.
- that means installing python2.7 if not allready installed
- execute the ../tools/o3ds_cdn_firm.py
- find the slot0x25KeyX.bin (google it or use the one from Plailect)
- copy the files to your 3ds sd-card
last big step
get mset install from this tut *credits to @
DjoeN
- Get rxinstaller.bin out of the rxTools package and place it in the root of your 3DS SD
- Choose URL and type in:
http://dukesrg.no-ip.org/3ds/cakes/?rxinstaller.bin
- Bottom screen should give a slicht flicker after that clsoe your browser, this will give you an error, ignore
- Now go to your "settings" "General settings" "Profile" then "Nintendo DS-profile"
- It should boot rxTools now
and done.
Next question will be ... linked nands or seperate them ... maybe search a bit.
for linked nands you are ready.
otherwise check first if you get into rxtools and then restart. go to settings and search for format. drop out your sd-card and confirm. this means you will have to install mset oncemore but has now seperated nands.
both has pro and cons so have a look by yourselfe
