I tried several times to apply the ssb update I deleted my save data as I kept getting the unnecessary data pop up and I couldnt find any update for ssb to delete so it I dont know what to do as the game wont launch or give me an option to start it without updating. I am on 5.4U spoofed to 5.5.1U I tried reinstalling it with the modified wupinstaller thats suppose to allow bigger updates that still didnt apply the update I let it sit for 45mins and another time for 2 hours still nothing after restart. I have tried using the update remover that still didnt do anything still get the pop up when I go into data management and yes I hit delete I let it sit for several hours so I hard rebooted it and its still asking to delete something thats not there so I am guessing I have a broken install and its not showing up. I dont know so what should I do at this point ill probably junk it I am going to wait see if anyone has any suggestions if not im going to do the wipe system option and if that dont work oh well im just going to junk it and save myself the headaches the preinstalled games still work but I cant get ssb to update or even play it so im done with it for now.

 

USA region update is 1.71GB.

When you go into your file manager, is there any SSBU entry at all?
You should also try redownloading SSBU, when you use NUSGrabber, put "192" for the version at the end of the command line options.
And if you have a different SD card you can use, also try that.

Your WiiU is not broken, don't worry. Worst comes to worst, just update to 5.5.1 and install the update normally. 5.5.1 is going to be exploited soon anyways because of Hykem's IOSU work.

 

Try launching SSBU once before doing the install as well, it might help success.

 

Try the update once more now after doing that, that is what you should get when tubehax is on, no worries.

Also, on your SD card, there are no folders inside of SD:/install/, correct? You only put the update files themselves, not another folder?

 

Yes after getting the 192 update and having tried launching like you just did.

 

Glad to hear! You can use this website to check:
