Huh. Good to know, will fix the package/wiki ASAP, AFAIR this is the first time someone reported this for the K4 (until now, we were only aware that it was needed for most Touch released since the EU release/5.1.x).
EDIT: Or not, there's a very decent chance I messed up when rewriting the instructions (... last february...), so thank you for the detailed report & investigation
