K770 Customer Pack = Buttons don't do the right thing?

My problem is exactly the same..
I unbranded from Vodafone to generic using these files:
K770_R8BC004_FS_MEDITERR_RED53.fbn
K770_R8BC004_MAIN_GENERIC_VI_RED53.mbn
HB1-06_Gen_CDA102568_4_R8A_GENERIC_MEDITERR

all of which i downloaded from here...
The process went fine, the phone is fully debranded (and faster I may add) but I have 2 issues:
I cannot assign a shortcut to the up button, as it is greyed out in the menu saying "Cannot set as shortcut" when i press it. It is defaulted to the photo viewer

Plus the answer and end call buttons do not work as expected..
the answer button opens up the web browser and the end call button opens up the shortcuts pop up menu...

What can I do? Rebranding is not really an option as i hate the vodafone stuff.. can i edit some file in the tpa folder or something like that so i can change these?

You don't know differents unbranded and branded software.
Unbranded haven't answer and end call buttons !!!
Only branded have answer and end call buttons!


Unbranded have:
internet button
Activity menu button

Branded have:
Answer call
End call

If you will back to Vodafone software must use these files:

K770_R8BC004_MAIN_VODAFONE_VI_RED53
K770_R8BC004_FS_VFE_LIVE_2_RED53
K770i_1205-3162_R2A_Vodafone_United_Kingdom

Ok, ok now I get it.., but still is there some way to find the files responsible for the functions of the buttons inside the FS and change them only? and what about the up button shortcut? I didn't find patches for any of these..
