I’ve been fiddling around the file system of the Nokia N9 lately. It’s not hard to do and actually quite fun to have shell on a linux device that fits in the palm of your hand.
First enable developer mode:
Settings > Security > Developer Mode
The phone will install an SSH server and also a Terminal to the home screen. Open the Terminal and you will be in BusyBox v1.19.0 shell.
Second, change the root password. Enter the following command to su to root:
devel-su
It will prompt for a password. The default is “rootme”. The prompt should change from “~ $” to “~ #”. Enter the following command to change the root password:
passwd
You will have to enter it twice. Then type “exit” to return to the user prompt.
If you type “gconftool-2 –help” at the prompt you should see a long list including a “s” option to set and sync a value and a “t” option with the values “int|bool|float|string|list|pair”
For example, use the following to install an image to the screen_lock screen.
gconftool-2 -t string -s /desktop/meego/screen_lock/low_power_mode/operator_logo /home/user/MyDocs/Pictures/filename.png
The image (filename.png) should be no more than 120×120 pixels and 1-bit (black and white). Space invaders comes to mind…
Or a flyingpenguin:
Maybe white is a little bright. The screen lock color can be modified by editing the following file:
/usr/share/themes/base/meegotouch/libsysuid-screenlock-nokia/style/libsysuid-screenlock-nokia.css
Easiest way to modify it is remotely over ssh. Open the SDK Connection app on the home screen. Select WLAN from the two buttons. It will show you the IP of the N9 and the password.
Once you’ve made a backup of the file, change the hex setting just below the line that reads LockScreen MLabelStyle#LockScreenLowPowerModeClockLabel. Red is #FF0000.
