I used this guide's (https://github.com/Plailect/Guide/wiki) instructions to update my 2DS from 6.0 to 10.3 via the cart update instructions. But even though I changed the date and time as instructed in Part 1, I can't use the browser at all, I can't proceed to install A9LH. Attempts to open the browser go immediately to an update nag. What do I do now?
