There are a handful of possible causes to an ARM9 error. These are generally related to a select few essential nand files that are either missing, replaced with garbage/corrupt/dummy versions, or contain wrong flag values.No problem, here's a picture of the error screen, I followed the 3ds hacks guide.
Running that script's Bypass Profile Setup might have set wrong flag values to the config savegame. Try this initial litmus test.
In GodMode9, go in the [1:] SYSNAND CTRNAND directory and press (X) on the data folder to delete it. This action will (more or less) do a Format System Memory. On the next boot to HOME Menu, your o2DS should bring up the new user setup [assuming of course nothing else is wrong with the 3DS firmware].
