OK, I really HATE the boot screen from Bouygues, so I did my own boot screen.
I found an Huawei boot screen from the u8100. I croped the files to the u8350 screen format, and here it is!
A nice boot screen for my boulder.
For the quickstart I read that the file size must be small, so I reduced the color ammount, took only key frames, and I got a quickstart boot screen.
Now to install it... To allow operator customisation these files are in /cust/ partition. For Bouygues Telecom it is in /cust/bytel/fr/media/
1- a functional devkit. If you used SuperOneclick to root your phone it is fully functional.
2- a rooted boulder
For windows users:
- Make sure you activated the USB debug mode,
- connect the boulder to the PC, activate the USB drive, copy the 2 files (bootanimation.zip and bootanimationex.zip) to the sdcard.
- desactivate the USBdrive,
- launch a cmd window,
- type "adb devices", you should see your device on the list
- type "adb shell", the shell starts,
- type "su", the # prompt appears,
- type "mount -o rw,remount -t yaffs2 /dev/block/mtdblock8 /cust", the /cust partition is now writable,
- on the boulder, use a file explorer (I use ES File Explorer and activate the root mode in the prefs) and copy bootanimation.zip and bootanimationex.zip to the place where your original files are (make a backup perhaps, in case you hate my work),
- if you want, as long as it is writable, delete the operator apk that you don't use (by me they were in /cust/bytel/fr/app/).
Done! you can reboot the phone and enjoy!
