Hello,You can start by making a customized version of system.img. As I said in another thread, it is pretty straighforward to extract the system.img. You'll need a debian based system or find the commands yourself.Read the guide in whole before starting !# This will create a new directorymkdir -p /mnt/system# Install cramfs toolssudo aptitude install cramfsprogs# mount the system.imgsudo mount -o loop system.img /mnt/system# copy the readonly system to an editable locationcp -rp /mnt/system /path_to_a_valid_directorycd /path_to_a_valid_directory and start cutstomizing. I suggest removing/Adding some apps in app directory.# Repack the systemsudo mkfs.cramfs /path_to_a_valid_directory my_system.imgFlash only system.img with the Flasher tools.WARNING : as I don't have received my aPad yet, I haven't tested it so YOU DO THIS AT YOUR OWN RISK.Maybe someone else can confirm/add details to it. Also be carefull that there is a size limit for the system.img. See HWDEF file, maybe there is some changes to do there.
