Hi, I’ve hacked initfs of my n800 to show my name and email as you can see in this picture. I know that it is not a big deal, but it can be useful to avoid undesired changes/mistakes when you work in a team that has more than 1 n800.This post is not only to show, but to describe how to do this hack.
- Download the image and flasher. (You can use the 0xffff if you prefer)
- Unpack the image:
flasher -F <image name> -u
- Mount the initfs.jffs2:
sudo modprobe mtdblock
sudo modprobe mtdram total_size=65536 erase_size=256
sudo modprobe jffs2
sudo modprobe loop
sudo dd if=/pathtoimage/initfs.jffs2 of=/dev/mtdblock0
mkdir /mnt/jffs2
sudo mount -t jffs2 /dev/mtdblock0 /mnt/jffs2
- The /mnt/jfss2 directory is read only, so you need to create another dir and copy everything preserving the files:
mkdir $HOME/myinitfs
sudo tar pcf – -C /mnt/jffs2 . | tar xvf – -C $HOME/myinitfs
- edit the $HOME/myinitfs/linuxrc using your preffered text editor. Look for “want_menu=0″ and add something like the text below just before it.
text2screen -t “Your Name” -H left -y 12 -s 3 -B 0xffff
text2screen -t “your_email@server” -H left -y 50 -s 2 -B 0xffff
- Create your new initfs image:
sudo mkfs.jffs2 -r $HOME/myinitfs/ -o $HOME/myinitfs.jffs2 -e 128KiB -l -n
- Flash it:
sudo flasher -n $HOME/myinitfs.jffs2 -f
That’s all. Enjoy it.
Another thing that I want to talk about is that I’m using the OS 2007 entire in a memory card (MMC) leaving free the main flash memory where I’m going to put Mamona. But this is a topic for another post…
You can do it also directly on the device without having linux PC with mtd modules and without downloading and extracting firmware, see initfs_flash script inside http://fanoush.wz.cz/maemo/#initfs
Excellent!
Isso foi bruto mermo!
[...] thing that I did was to add the code below in the begin of boot() function in linuxrc of initfs (My last post explains how to edit and flash the initfs in your pc). load_mmc_modules root_dev=mmcblk0p2 [...]
