Okay, as people have been having trouble with the CUST here are the .DMF files and the instructions of where to inject them:
Before starting this,
MAKE A BACKUP OF YOUR ORIGINAL CUST! as if you want to revert to the standard theme you will only be able to do this with the original CUST (spare flashing which will wipe your phone of data)
Okay, onto the injecting of files:
Firstly open your original CUST using WinImage and select the
'LGAPP' folder. Then open the
'DMF' folder.
First we will start with musicplayer.dmf : Open the folder named 'Common' that is found in the 'DMF' folder. Now inject this into the folder and overwrite the original file.
Repeat this process (injecting into the '
Common' folder) with
Popup_HR, Popup_VR, PopupAniConfirm, PopupAniConfirmHR, PopupAniConfirmVR, PopupAniWarningHR and PopupAniWarningVRNow open the 'TopMenu' folder which is found in the 'DMF' folder. Take the new TopMenu and inject it, replacing the original.
Finally, go to the 'DMF' folder and inject the file Screen.dmf.
This does not go into any subfolder (just LGAPP>DMF) and should replace the existing Screen.dmf in the 'DMF' folder.
Browser:
If you also want a new browser theme, select the folder LGAPP > 'Obigo'. This should contain two folders called ids and ref. Take the ref folder from the .zip I uploaded which is found under 'New Browser' and inject it into the CUST. When asked to overwrite the existing folder select 'Yes'
Now save your CUST image and close WinImage. Send the new CUST to your phone using KP500-Utils and see what you think.

Note elements of this theme:
Whereas with normal Cookie or italian firmware you have to change the font by a method using your computer you can now change it by going to the main menu > Settings > Screen Settings > Font
Also the volume control on the widget screen has a mute button for music playing (press volume up or down side buttons to see this)
Elements of prada theme are used such as music player (so no more cookie pink colours

)
Now hopefully you should all be able to use this and there should be no more problems with CUST incompatibility.
Please tell me what you think about the general combination and also the browser theme.
Enjoy
