I have the tutorial bookmarked on my home computer. I will post a link later tonight after work. It looks like it gives step by step instructions on each part of building a theme for those of us that are new to it.
@jdmstar
Thanks! I will check that one out tonight.
Yea they give you step by step but most of it is redundant.
Like all you do is create a folder under whatever you want to name your tehem.
Lets call it Matrix.
From there to lock it to a certain wall paper you create the image in the size of the bg and lets say 420x380 (this is hypothetical number im not sure the actual size since all my themeing stuff is on my laptop)
and you create a wallpaper in that scale and SAVE AS > Wallpaper.PNG and leave it in that folder. You can do the same for the dock, and it has a certain size it should be and certain name as well.
For all icons on your phone lets say you have all the stock icons, plus custome ones, create a folder named: Icons , within the MATRIX theme folder, and put all your icons there, lets say you want to change the original YOUTUBE.PNG pcuiture to your custom one of an emblem from a car, just create a PNG file in the scalre that it should be and name it Youtube.PNG and put that in the Icons folder.
After you are finished making it, upload your new theme to winterboard,
1. SSH into phone.
2. go to root.
3. Find applications > Themes.xxxxxx
4. Create new folder or just drag and drop your matrix folder.
Go back to iphone, open Winterboard, your theme should be in thre, uncheck all other themes check yorus, and VIOILA!
let it load and you got yoru enw custom theme.
Like i said best to learn is download a theme to your phone from CYDIA and then play with the file struture learn where all the files are placed, and how they are named, and simply create a new folder and follow the same naming and file strutcure upload via SSH and your done!
