Yes, I understand this, but actually I have a bit different case, because my touchscreen won't work with KK at all, but works absolutely fine with JB. So for some reason, the firmware of my new touchscreen won't update when flashing the KK rom - and wondering if someone has any idea what to do about it.

Well, there's definitely something "defective" because the firmware of the touchscreen won't update from JB -> KK. But function-wise, it's working ok - but only with JB. With KK it's completely dead.
