How To Make a Notification Pulldown Background ON YOUR PHONE...

1. Apps I use: Root Explorer Photo Editor Ultimate (Free can do most of the modification. But I recommend using the Paid Version because it also has more options like Transparency and other useful tools.)

2. Download a Large JPEG or PNG picture/background you want to use. Save it onto your sdcard. 3. I personally use a BLANK Black background set to slightly larger than our screen size. This will be in the downloads below. This will be used to OVERLAY your picture to it.

4. Now open Root Explorer to where the BLANK Black background is located. Now choose to open it with Photo Editor Ultimate (free or paid)

5. Now when the Menu comes up Choose: Combine, Overlay, Browse, and navigate to SDCARD, navigate to where you saved the BACKGROUND PIC you want to use and choose it.

6. Move the pic around until you have it positioned where you want it. I move it close to where I am going to crop the picture at. Hit Close. Hit Yes.

7. Choose Resize/Crop

8. Choose Crop

9.Touch on the screen close to where you want to crop the pictures together. (THIS IS A LEARNING CURVE TO GET IT RIGHT.) You WANT to crop it so you can draw a rectangle that leaves SOME of the BLACK BACKGROUND at the top.

10. Now hit the button on the top to draw the rectangle.

11. Click the Top Button to CROP

12. If you like the crop choose CLICK TO CLOSE

13. At CHOICE hit Yes.

14. Now Choose RESIZE /CROP and THIS TIME choose RESIZE

15. Hit the SETTINGS button

16. Now choose FIT SCREEN SIZE

17. It should be CLOSE to 720x1280 for our phones but slightly More/LESS height will still work. (Again a learning curve with practice...)

18. Hit the back button and choose YES

19. Now choose PREVIEW to see how it looks full screen. I start to pull down my notification bar to see where the NEW pic is going to line up.

20. If it looks like it will be at one of the Notification pulldown bars and looks good then your golden.

21. Hit the back button again and choose YES.

22. Now choose SAVE, OVERWRITE OPENED IMAGE, Hit Yes, Hit OKAY

23. Hit the back button and choose YES TO CLOSE.

24.Now it will go back to where the Blank Background was located in Root Explorer. Hit the menu button and choose refresh. Now you will see the newly made back.PNG of your background YOU created.

25. With Root Explorer go to where you downloaded the CWM FLASHABLE ZIP FILE. Long press on it and choose EXTRACT ALL. Now choose GO TO EXTRACTED.

26. Navigate in root explorer to where you have your NEW background back.png file. Now LONG PRESS on the back.PNG and choose COPY. Now navigate to where the extracted CWM FLASHABLE ZIP is located.

27. Now navigate to the CWM ZIP FILE (also on the downloads section in this post). And PASTE (CHOOSE OVERWRITE IF NEEDED). Navigate by clicking like so: CWM-FLASHABLE-ZIP, MORPH, SYSTEM, APP, SYSTEMUI.apk, RES, DRAWABLE-XHDPI, and PASTE

28. Now I use 3 different file names so these morphs can be used on different ROMs. So next I use root explorer and copy and paste the back.PNG 3 times by long pressing and choose copy, then hit paste. Now I name the three .png files: back.png, notification_panel.png, and pulldown.png

29. Hit the back button until you back at the extracted CWM-FLASHABLE-ZIP and LONG PRESS and choose ZIP THIS FILE

30. When it is done Choose GO TO ZIP and move it to your SDCARD.

31. NOW YOU ARE READY TO FLASH THE NOTIFICATION BACKGROUND MOD YOU CREATED IN CWM RECOVERY... HURRAY FOR YOU... YOU JUST LEARNED SOMETHING I HOPE...
