If you're perm rooted you could do this and remove the apks via adb. Are you familiar with adb?

Sounds like both issues are due to dalvik cache.

If you touch my name and look.for threads created by me, look for one called "how to easily remove system apps".

Whilst doing this, when you are still in adb shell;

Type exit and press enter.

Type adb push "c:\android_audio.mp3 /system/customize/resource/android_audio.mp3" and press enter. Thus will push android_audio.mp3 to the directory. Assuming it is on your c drive

 

I'm using LeeDroid and have a somewhat different issue with android_audio.mp3. I've used ES File Explorer under root to rename /system/customize/resource/android_audio.mp3 to ...mp3.bak, but the (sorry) horrible boot sound in LeeDroid doesn't go away. Looking at the file using ES File Explorer after a reboot it shows the .bak extension as I would expect. What I also find odd is that file is 0 (zero) bytes long, I thought it contained the boot-up sound. What's the secret?

Ooops! Found out myself. There is an android_audio.mp3 file in /data/local that I hadn't seen before because ES File Explorer didn't have root authority at the time. Renaming this file cured the problem and the sound is now gone.
