Hello, I have an O3DS XL with an NNID that isn't mine, it was the previous owner's and I do not know the password and have no way of getting it. I am on 11.3 and have installed a9lh and everything works fine. I want to remove the NNID and even format without losing a9lh, I understand I'll have to reinstall the CIAs I need, presumably through injecting FBI into the H&S in hourglass again? Will formatting remove the NNID? Will my a9lh stay? I've updated to 11.3, so I'm a bit paranoid. I do have nand backups if needed. Thanks!
