okay, first thing is: mind your language! If you have no respect for the others, you won't get any respect!
To make skins, you have to know your choice of graphics program. It can be Photoshop, Paint Shop Pro, Gimp, or heck... Even paint as well, but that's crappy.
Then, download the Resource Editor from this website at:
M6/M3 resource editor v1.22
Use it to open a firmware resource file (resource.bin) that you've downloaded with the firmware version you're wish to skin. Extract all of the pictures it contains by right clicking the pictures folder and selecting save. It'll extract all pictures into a directory where you can directly edit them with your drawing program. You may also use Skin Viewer Reloaded at:
[V1.3]Skinviewer Reloaded
to view the extracted pictures how it would look like on the M6.
When done editing, go back to the resource editor, right click the pictures folder and import all previously extracted then modified pictures. Voilá, you have a skin. (Only the resource.bin is needed and it only works with the m6(sl).ebn it was bundled with when you've downloaded the firmware.)
There is no simpler way than this.
P.S.: Also, do not expect such guides be made for only holy you normally, you're supposed to look for sollutions to what you want yourself, you're not the king of the world himself you know.
