I posted this for the guys in the UD section under my theme. I put some thought into it. Maybe it can help some guys out. Here is my order of operations on porting my theme from rom to rom. 1.) Download new UD release, or other new rom 2.) Extract UD release to somethere. I will call it c:/somewhere/UDNew/ (I use winrar) 3.) Take one of my existing theme update.zip's 4.) Extract my update.zip to somethere like c:/somewhere/ECLThemeOld/ 5.) Download theme-porter (by Daneshm90) 6.) Extract theme-porter to somewhere like c:/somewhere/Theme-Porter/ 7.) Copy the app and framework folders from c:/somewhere/ECLThemeOld/ into c:/somewhere/Theme-Porter/old 8.) Copy the needed files from c:/somewhere/UDNew/ to c:/somewhere/Theme-Porter/new (ie copy UD's newest versions of the apk's from his rom that match with what I have already themed) 9.) Phone.apk and contacts.apk rarely change, so I now copy my themed versions right over UD's versions under c:/somewhere/Theme-Porter/new. I do the same if UD has the apk's missing like gmail.apk and launcherpro.apk. 10.) Now I run the Script.bat in the c:/somewhere/Theme-Porter/ folder. It will do it's thing which is replace all of UD's png images with the ones from the apk's from my theme. 11.) Once done all images should be moved over into the apk's located in c:/somewhere/Theme-Porter/new. This is 90% of the battle. 12.) Now for the xml's. These don't transfer with the images during theme porter. The framework-res.apk now located in the c:/somewhere/Theme-Porter/new needs the xml's moved over. Go to c:/somewhere/ECLThemeOld/framework/ and change the name of my framework-res.apk to framework-res.zip. Now extract framework-res.zip to c:/somewhere/ECLThemeOld/framework/framework-res/. 13.) you can use 7zip for the next step but I have always liked winrar. Go to c:/somewhere/Theme-Porter/new/framework/ rename framework-res.apk to framework-res.zip. Open framework-res.zip in winrar. Navigate to /res/drawable/. Click add Select files to add: for example progress_horizontal.xml from c:/somewhere/ECLThemeOld/framework/framework-res/res/drawable/ will make your progress bars the blue color like my theme has. Likewise you can use some of the following colors from haxzamatic: Green = GSProgress.zip Sense = SenseProgress.zip Dark blue = DarkBlueProgress.zip Orange = Orange Progress.zip Once done selecting files click OK. Then click OK again at "archive name and parameters" dialog. Now the new progress_horizontal.xml is in your framework-res.zip. If you want the fancy animation by RedmanX do the same thing with all the xml's in the c:/somewhere/ECLThemeOld/framework/framework-res/res/anim/ folder. Finally rename c:/somewhere/Theme-Porter/new/framework/framework-res.zip back to framework-res.apk Now to package it all up. 14.) Download Update.zip 2.0 Modifier/Creator [Script] (by Daneshm90) 15.) Extract Update.zip 2.0 Modifier/Creator to c:/somewhere/Update-Zip-Packager/ 16.) Copy the contents of c:/somewhere/Theme-Porter/new/ to c:/somewhere/Update-Zip-Packager/placehere/ 17.) If you want the thicker fonts and boot animation I usually use copy fonts and media folders from c:/somewhere/ECLThemeOld/ to c:/somewhere/Update-Zip-Packager/placehere/ 18.) Now its time to make the update.zip. Run Script.bat in c:/somewhere/Update-Zip-Packager/ 18a.) clean our previous update-script data 18b.) select 1 to create new update-script 18c.) select 1 to tell it to copy directories 18d.) tell it to save the directory to SYSTEM 18e.) tell it where to copy to app or fonts or media etc. 18f.) tell it what to copy from placehere folder app or fonts or media etc. 18g.) repeat for as many folders as you have. then type 8 and hit enter for done creating update-script. 18h.) type 2 and hit enter and it will create your update.zip and save it in the c:/somewhere/Update-Zip-Packager/ folder as update.zip Now you all know what I know.
