Thank you again!
Well yesterday i wasted 3 hours with getting the emunand autoboot done, but rxtools came up with Native_firm: 4 Errors.... somehow the latest pasta-cfw didn't wanted to work and so on...
Only thing which i got running was menuhax on sysnand (so emunand shouldn't have menuhax since the emunand is before i installed menuhax on sysnand).
Since RXtools took 3 hours of my life and the 1.3beta7 of pasta-cfw also wanted to troll me with not loading - i decided to switch to cake-fw since it hast nand autoboot as a feature and i got it running (after the first boot blackscreened and i almost went enrage - the second boot showed me the cake-fw bootscreen yay!)
And now i can finally come back to the emunand topic which had cost me nerves :-)
I've read the Topic which you linked already (which gave me the first questions).
According all the stuff we have been talking now and the progress i currently have, this would be my next steps:
1. Use Cake-FW to boot into emunand (emunand partition has been made with ninjhax-gateway while doing the tutorial)
2. While in Emunand, i'm going to format system data to unlink both nands so that sysnand and emunand are thinking they are different consoles (I should backup the files on the sd-card since this will delete all files like homebrew and stuff right?)
---quick Midquestion - to disable Signaturechecks (start homebrew and install cia-files on emunand) i have to check "Disable Signature Checks" in Cake-FW configuration right?
3. Check if FBI is installed there if not inject it somehow (i think gateway can do this?)
4. get sysupdate cia installed into emunand (with FBI from step 3)
5. use 3dnus to get 9.5 Update and install it with sysupdate
6. Emunand is now up to date and can be used "normally"
7. Profit!
