N9 Developer Mode

First thing you wanna do after getting the N9 is enable developer mode (found under Settings > Security menu). Once activated, the phone downloads a 1.2MB developer mode bundle package, and restarts. After reboot, you'll now have a Terminal app and an SDK Connectivity app.

It's a bit difficult to type on the Terminal's on-screen keyboard. Good thing the SDK Connectivity app comes with a VNC server for you to remote access in.

You can also download more developer tools. For me, all I need are Networking (tcpdump) and Utilities (wget, nano, and x11-utils).

Getting root
Run the Terminal app.
Type devel-su
Default password is rootme

Enabling VNC
Can be enabled on the SDK Connectivity app.
Or download Nokia's NetView app. Does the same thing.

Enabling ssh/scp
Log in to root account
passwd user
Give a new password to user user
ssh user@localhost
Enter password
Run SDK Connectivity to get the WLAN IP address
Connect to phone via WinSCP/putty

Installation files have the *.deb file extension.

Generic install instructions:
 - copy deb file to N9
 - install using "dpkg -i *.deb" command
 - most often than not, you'll get some warnings
 - to fix, run the ff. commands:
apt-get update
apt-get -f install
 - if it specifically mentions some missing package(s), download using apt-get and install:
apt-get install
apt-get -f install

Built-in video player is very picky about the files it plays. For the record, the phone came with these video files:

Dolby Soundscapes
2:35 71.3MB
864x486 h264 @3486k
E-AC3 @ 384k

Nokia Pure
2:53 76.8M
854x480 h264 @ 3349k
E-AC3 @ 384k

Couple of alternative players out there are VLC and the kmplayer/mplayer combo.

Get the VLC installer here:

A few website will mention http://www.irunvlc.me/, but that domain's already obsolete.
An older version of the VLC packages can be found here:

If the installation process spews out some error messages, run these additional commands:
apt-get update
apt-get -f install
Running the VLC app gave me a desktop UI. Hangs a lot and didn't play any of the videos.

A little bit better than VLC, but not much.

Browser doesn't work at all (for me). 20MB download, too.

Awesome little phone, but the lack of proper working apps is killing it. Personally, I doubt if Sailfish or a fully-working Android port will ever come and save Lankku.
