MobileJaw reader Tisha, asked about how to remove the AT&T animation that takes place on startup and shutdown of your device. This is the same animation used on any of the Windows Mobile 3G smartphones that AT&T carries – the one where 3G clouds fly by and leaving a trail that transforms into the cellular reception bars. On other carriers this a different animation or sometimes just an image that shows the carriers logo or something simple like that.
The steps below will walk you through removing this animation and there’s even details about what you need to do to display your own graphic. One special note – If you have a Samsung Jack or Propel Pro, you can not remove the startup animation. If you do this, the screen driver fails to load and you can no longer see anything on the device. You can, however, connect to the device using Pocket Controller Pro and reinstate the startup animation and all will be fine again. Again, this is only a problem on the Propel Pro and the Jack. All other devices have not displayed this behaviour.
1) The first thing you need to do is remove the application lock from your device (Windows Mobile Standard or non-touch devices only). To do this, check out my other post about Removing Application Lock.
2) Install some sort of registry editing tool. For on device editing, which is all that would be required in this case, I would recommend PHM’s free registry editor.
3) Run the registry editor and browse to HKLM / System / Startup / 1
4) Here you should find a value by the name of DLL. Highlight the value DLL and press the Menu / Delete to completely remove it. (Samsung Jack and Propel Pro users – do not delete this value!)
5) Browse to HKLM / System /Shutdown / 1 and you should find another value with the name DLL. Highlight and remove this one as well.
At this point, you should no longer have the startup or shutdown animations. You can reboot your phone and test it out. But I’m not done with this hack. Instead of the carriers animation, why not add your own image? Here’s the steps to add your own graphic on startup and shutdown.
6) In the registry editor under HKLM / System / Shutdown or HKLM / System / Startup create a new Value and set the type to be String.
7) Name this new value “Splash” without the quote,s and set the value to be the complete path to your picture. I recommend against putting this picture on the storage card. It should be on the main memory of the device.
Save your new value and back out of the registry editor. Reboot your phone and enjoy the new graphics!
In case your looking for something to replace that image with, here’s a very fancy Mobile Jaw logo in 320×320, 320×240, and 240×320. I just placed the size I need in the My Documents folder and then set the Splash value to “\My Documents\MobileJawSplash320240.png” – without the quotes. Enjoy!
If you have any problems, let me know. Or if you just feel like sharing your success, I would love to hear about it.
