Hi guys

I have a z550i r6CA009 and I have a couple of questions about what is possible:

1) external display; what modifications are possible to it?

2).vkp patches how do you apply them to this phone; do you have to use FAR manager ,
or is XSS enough?

3)how do you load diffrent open phone sounds?

the biggest modification that I want to make is that the radio works without the headset
but from what I have found out this is not possible.

finally I also want to find out if there is a backup of the phones filesystem
(managed to nearly brick the phone a couple of times so far) :)
