As I've already told and explained in other places this software has been advertised: using this will lead to a ban, in almost all cases.
It is known that Nintendo checks for mismatching erpt and prepo save data, and bans in consequence. Using this on your console will get you banned.
The only case where this would be considered 100% safe would be if you absolutely never connected to Nintendo's servers using your console.
of course it is a real possibility
but at the moment those who have used the cleaning method through hack disk mount have not been banned
I had my console more than 4 months without ban only blocked the url of posts that use nintendo
I could not continue the test because I was banned while trying to use the certificate of a cartridge in an nsp I was banned in 5m so don't do that ever.
but the proxy I closed it a few days ago because emunand appeared in the atmosphere
at that time it was used by many people and they were not ban
the proxy start on 03-22-2019 and end at 1? -09-2019
if you have a backup of your nand or have never connected with nintendo much better, and I recommend that, than using Haku33
but for the moment one thing is for sure, going online doing nothing is ban and
If you never go online, you are banning yourself
and for those who don't have a clean copy, they don't have many alternatives
but of course I only propose a method that is working, it is each one's decision whether to use it or expect something better
