How to change notification pane image [solved]

I've just installed an ICS Rom (HTC Nameless) which has background images in both the notification pane and app drawer. These images don't appear to be well planned, because I can't read anything very well on top of them.

I'd like to either change or remove both images, but don't have the faintest clue of where to start looking. I have tried a few apps that have utilities for this, but none of them seem to work. I know my way around the filesystem alright, so I would like to change them manually.

My device details are as such: Phone: HTC Desire C Rom: Nameless (ICS 4.0.3) v7.3 build 4 Rooted: yes

If anyone can point me in the right direction, I'd be very glad :)

======== SOLVED ========

I can't answer my own question yet, but won't be around to do so when I'm allowed. This is what I did to fix it (without touching a pc)

I used ES File Explorer, and "Photo Editor" from the play store to accomplish this.

  1. Copy the original apk (systemui.apk and Rosie.apk) to a writable folder
  2. Using ES File explorer, long press on the apk and choose 'extract'
  3. once the extraction is complete, find the image you want to change, under "res/drawable-mdpi"
  4. Edit the image using Photo Editor (I just made it black), and overwrite the original.
  5. Using ES file explorer, recompress all of the files you got from the extraction, using the ZIP extension
  6. Keep the original apk, renaming it to something like "systemui.apk.old
  7. Rename the new zip file to "SystemUI.apk", being sure to match the original apk filename in spelling and case.
  8. move your new SystemUI.apk to /system/app, overwriting the default
  9. Reboot, and enjoy.

Caution: this may not be the generally accepted method, and therefore could potentially cause damage to your filesystem. Be sure to perform a nandroid backup, and back up your original apks, JUST IN CASE.
