ok - so I found out that indeed in the telefony.apk the folder is called: drawable-xxhdpi-v4
So if I rename the folder in your zip under telefony as well with drawable-xxhdpi-v4 - Hendrix should appear as well as a caller picture.
So far so good
- but I don't think I can solve the big caller photo issue just by resizing Jimi with paint as all of my contact pictures are small again after flashing your zip.
I agues it is somehow undoing th big caller photo mod of the lyapoya pack - so I have to decide what I like more - or may be I could flash the lyapoya mod after you zip again?
