Changed the metadata of the dictionary and the three guides (named *_new.* in the zips) and added the corresponding thumbnails which can be sideloaded to
/system/thumbnails
The metadata is per
post #64 with fake but new and unique ASINs.
The thumbnails were generated by
quiris program per
post#74.
YMMV: I am doing this blind/untested on a K3, hope it works for you
Grab them
from the OP.
