Now you have the new Eclair in your Spica, but wait, firmare EXXJCE is french firmware, so you’ll get your Spica language in French, to change the language, enter paramètres menu at bottom corner then choose Paramètres de langue then Langue et règion and select your language.
Rooting Your New Eclair
In some cases, you may need your Spica to be rooted in order to install some applications like shootme, my favourite screen capture application. This is just optional, you don’t have to follow this step. I use LkMod v2.5.1 by Leshak that based on EXXJCE firmware to get my Spica rooted and get some additional features like live wallpaper and custom logo while booting my Spica.
LkMod 2.5.1 features:
- New phone.apk (from xdadev)
- Helixlauncher as default home (can be switched with default Pantheon)
- Live wallpaper
- Root (su)
- Busybox
- Remount
- fdump for backup
- Custom logo
What you need:
Create your custom logo (Optional)
Default logo comes with LkMod can be replaced with your own logo, you can replace the logo with your own using Photoshop or other image manipulating software.
How to change the logo:
- Install the GNU tar for windows, default location is on C:\Program Files\GnuWin32
- Extract LkMod-2_5_1-PDA.7z and you’ll get LkMod-2_5_1-PDA.tar
- Extract LkMod-2_5_1-PDA.tar and you’ll get four files: cache.rfs, datafs.rfs, logo.png and zImage.
- Create your own logo with 320×480 size and PNG file type. Warning: The size of logo file must be between 30-40 kb or the phone will never be able to boot!!.
- Save as logo.png and replace the default logo.png
- Package the four files using GNU tar command line program
>C:\Program Files\GnuWin32\tar -cvf LkMod-2_5_1-PDA.tar cache.rfs datafs.rfs logo.png zImage
- You’ll get your own LkMod with your own custom logo (LkMod-2_5_1-PDA.tar)
How to flash
- Select spica_jc3.ops in Select OPS field.
- Click Reset Files to clean the fields.
- In Select Images to download panel, Select LkMod-2_5_1-PDA.tar into PDA field.
- Don’t select One Package option and Debug Option.
