The Android experience VII

Hey guys,

thank you so far for the great feedback in the comments of this blog I appreciate this very much.

Well, it’s been a while since the “end” of the experience. I’ve done a lot with my mobile, played with some apps, widgets, but removed most of them. One position was left open (even if I forgot it to mention it in the prior parts):

• The T-Mobile welcome and shutdown Animation

I forgot this by myself. During a reboot today (having some trouble with my operator) I saw this bootup animation again. My pulse raised to the sky

I’ve played a little with my LTE (Linux Terminal Emulator) and hacked this into the prompt (as root of course):

# ls -R | less

this lists the current working directory with all it’s subdirectories and returns them. I piped the output to the pager (less) and saw the result. Guess what I found:

./system/media: bootani.qmg TTS samsungani.qmg video audio   [...]   ./system/media/video/shutdown: shutdown.qmg

 

I think this is what I need. The startup (bootani.qmg) and the shutdown (shutdown.qmg) animation. One other cool “discovery” was the directory:

./system/media/audio/ringtones

I think this could be the path where the ringtones are stored

So, I did a little

# busybox -o rw,remount /system

followed by (This will create a backup of the startup animation and the shutdown animation):

# mv /system/media/bootani.qmg /system/media/bootani.qmg.bak # mv /system/media/video/shutdown/shutdown.qmg /system/media/video/shutdown/shutdown.qmg.bak

and rebooted my device. During the shutdown, no animation was displayed. During the powerup a sound was played, but no animation was displayed. I did the following:

# mv /system/media/samsungani.qmg /system/media/samsungani.qmg.bak

without effect and reverted the change. I’ll dive a little deeper to find the powerup jingle in the filesystem and I’ll update this page if I found the file.

*** Update ***

I’ve just found the soundfile in /system/etc!

Do the following to remove the sound during the powerup sequence:

# mv /system/etc/poweron.snd /system/etc/poweron.snd.bak

A reboot confirms this

Find below a short shellscript which will do all the stuff for you:

#/bin/sh # this will remove the startup and shutdown animation on # tmobile branded devices (tested only with Samsung 551)   echo 'remounting the /system filesystem rw' busybox mount -o rw,remount /system   echo 'backing up the files in /system/media' mv /system/media/bootani.qmg /system/media/bootani.qmg.bak mv /system/media/video/shutdown/shutdown.qmg /system/media/video/shutdown/shutdown.qmg.bak   echo 'backing up the files in /system/etc' mv /system/etc/poweron.snd /system/etc/poweron.snd.bak   echo 'rebooting the device' reboot
