I decided to detail and share how I used 7zip to Theme my favorite ROM. Im doing this because I found it a bit tough to find a detailed guide that contained all the steps. Hope this will help some people who would just simply like to change a battery or signal icon, or whatever.

Have you ever seen a ROM that you really liked the icons but it was not for your phone. Well I did so heres what I did.

1. Download 7zip.

2. Download your current ROM, and the ROM which contains icons you like.

3. Right Click on your current ROM, choose 7zip and choose" extract to "what ever your rom is called"". This will create a folder with contents of your ROM.

4. Do the same for the ROM that you may want to take icons from.

5. Now start opening up the folders. I like to keep one ROM on one side of the screen and the other on the other side. Depending on whether the two roms are for the same phone will determine whether similar files will be in the same location. For the most part you will be opening framework_res.apk and systemui.apk.

6. Opening these apk's is as simple as following step 3 again. Right click apk, choose 7zip, extract to whatever apk is called.

7. Go into the folder of the apk, go to res, go to different hdpi folders, there may be a few. I found it helpful to have both roms open at the same time. Looking for icons of the same name.

8. So you've found the icons you want to change. Once you are ready to copy them from one rom to the other, you must be certain they have the same name, if they dont, then you must change the name of your new icons to match the ones you plan on replacing. Do this before copying them. When you copy them over its important that your computer ask you if you want to replace the file of the same name. That means it does in fact have the correct name.

9.This is where I got confused, putting it back together again. So here is what you do. Back out of the folder that you just changed all the pngs in. Lets say its drawable hdpi. Keep this drawable hdpi folder handy cause you will need it in a moment. Now open up the folder which contains your ROM in a seperate window. Lets say we are changing stuff in the systemui.apk. Navigate to the original apk for systemui, not the new folder of the same name.

10. Right click it, Choose 7zip. But this time select open archive. Now in archive navigate into the res folder and you will see drawable hdpi.

11. Right click it. and delete it. Now remember I said to keep the other drawable hdpi folder handy....drag and drop it into the archive to replace the one you just deleted. Now close the window. Do this for as many system apks you choose, most common are like I mentioned earlier framework-res and systemui, but you may want to change things in settings, dialertabactivity, contacts....etc.

12. Now you want to put these newly themed apks back into the original rom. Its easy. Keep the newly themed apks handy.

13. Right click on the original rom zip, choose 7zip, choose open archive. Navigate to the apk you want to replace. Delete it. Now drag and drop the newly themed one into the archive. Repeat this process for all the apks you may have changed.

14. Close the archive window and install the newly themed zip in cwm. You may want to add something like a V1 onto the end of the newly themed rom, that way when you copy it onto your sd, you can keep the original on there as well.

Hope this will help someone get there rom exactly how the like it...and if it did...hit thanks.
