R4 Strange message

I hope this is allowed to ask, i read the comm rules and didn't see anything being i wasn't asking about anything illegal which usually comes with this device. but if i am please delete and excuse.

So i have been having a little bit of trouble with my R4. I have been trying to update to kernel V1.18, from my previous version (please don't ask what that previous version was i really have no idea, it may well have been the original version which was loaded upon it when i got it). upon reading the instructions on how to update, i have got something wrong being whenever now when i try to boot it up it comes up with the following message

(excuse crappy picture, taken from 2 megapixel cell camera obviously hard to read but maybe someone will recognize it and know the problem.

I think i may have deleted an important file. (i couldn't see anything, all the Ds_menu and Ds_mshel files are still there)

Also does anyone know if its possible to switch the language from Japanese to English?
