I was on a customized firmware, downgraded to 1.5 again and then tried to upgrade to the current legit, but it doesn't let me. From what I understand my registry keys or something are off when you used custom firmware. Is there any solution to this? If you know, please explain slow because I'm not super-great at this stuff and had to use really good guides(found em on here) to get the custom firmware in the first place.
Thanks in advance.
