Well.. You could say I'm totally n00b with Elf XD !!

but, when I'm learnt, I'll help another people too..
Here I tell what I've done in order to gain Elf...
1) I crossflashed my Z610i to W660
2) Repairing camera stuff's, OLED display, and patched the quick access patch
3) I created ZBin, config, ini, and daemons folder inside other folder in both phone memory and card memory
4) Put DYN_CONST.bin on phone's other/config/
5) Patched elfpack.vkp and elf.lib.vkp for R8BB001
6) I put bookmanager.elf , masterelf.elf , and screenshooter.elf on phone's other/zbin/
7) I could run masterelf.elf for display battery temperature and modified clock appearance, but when I started screenshooter.elf then pressed my musicplayer button, my phone wap crashed...
Now, what should I do?? I totally confuse about the next step because I read in so many tutorials, and all of their guide is what I have done!! (Don't you know what I mean?! I mean, I've done the tutorial's steps untill I got stuck because the elf doesn't work)
So, I want to ask few questions
a) Is there any incomplete steps due to the working screenshooter.elf?? If there is, so what?!
b) If you said I must apply another strange file, could you post the direct link?! So far, I've browsed and only found these kind of files: .vkp, .lib.vkp, .bin, .elf
So if I must apply another file type, I confuse...
c) I found screenshooter.eww, errr what is this??
Thanks for your attention
Any ideas are appreciated!!
