first I like to thank you all for helping me out (I am really in a bad mood because of the errors).
I use reinand/menuhax (sysnand 9.2 out of the box, never downgraded) on EMUnand 10.7 and until today every install worked flawlessly. I just wanted to update a game (zelda hyrule legends warriors) on 1.3 and noticed that neither the .cia nor the eshop update would work. so I deleted the game completely and now I am trying to reinstall it.
I can write and read from the SD no problem. I have around 10GB free (should be enough) and I just installed the newest FBI 2.2.1 correctly. So I guess the card is OK. I will give the new FBI installer a try but socketpunch seems to not install via network on the new FBI. so I am copying the 2GB game to the SD card from card reader now and try to install it using the latest FBI version.
The network install feature on FBI 2.2.1 works fine for me with SocketPunch, if that's not working for you then there is a problem there already.
You installed FBI 2.2.1using the version injected into the Health & Safety app? If yes, then this proves that your SD card is fine and that CIA installation on your console is fine. So this means that the problem is either with the Hyrule Warriors Legends CIA you are trying to install, or the previous installation (bad ticket?).
What you can try:
• Try to install another (preferably small) game and see if that works (optional since you probably installed the FBI 2.2.1 CIA, it should be enough)
• If the above works, redownload the Hyrule Warriors Legends CIA and retry
• If it still does not works, delete the Hyrule Warriors Legends ticket using FBI (be
extra careful that you are deleting the right ticket), then reinstall
Sorry if you already did some (or all) of those steps, just making sure here.
(and you are welcome, I hope it will get sorted out eventually!)
