Hardware modifications

/* TODO: USB pre-broken fix */

Initial setup

Everything about Firmware Flashing


Download flasher from the repositories

/* TODO: Use open source flasher */

Download the firmware flasher: Flasher & SDK Downloads

Download the latest official Nokia Firmware Images for your N900: Firmware Image Downloads 

 RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin
 md5sum: 488809ff96a0a05479d692e9f77aeb4f
 RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin
 md5sum: b9f8690318a3be61767826d15b8c1784

Flashing the device

The following flashing procedure has proven the most stable to me:

File:warning.pngAlways use a fully charged battery!

  • Turn your device off, disconnect USB
  • (As root) flash the FIASCO firmware image: 
 flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f
  • When you get "No suitable USB device found" connect your N900 through USB.
  • Wait for the flashing to finish.

File:warning.png Don't reboot

  • Flash original eMMC image: 
 flasher-3.5 -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f
  • Wait for the flashing to finish.
  • Reboot the device by _reinserting_ the battery

Upon first login, enter your locale settings (Timezone, local time, etc.).

Run latest official Nokia SSU (upgrades your device firmware to V1.3.1) by launching App manager / Update from the applications menu.

Getting root access

1001 ways of becoming root

  • Add the Extras-Testing repository to the Hildon Application Managers catalog 
 name: Maemo extras-testing
 uri: deb http://skeiron.org/repo/repository.maemo.org/extras-testing/ fremantle free non-free
 dist: fremantle
 components: free non-free
  • Add the Extras-Devel repository as well 
 name: Maemo extras-development
 uri: http://extras-devel.merlin1991.at/ fremantle free non-free
 dist: fremantle
 components: free non-free
  • Disable OVI repository (conflicts with CSSU)
  • Wait for repository update to finish (Hildon Application Manager is slooow) and install 'rootsh' from the system section.
  • To get remote access over the network (way more comfy) install SSH server by launching XTerminal from the application menu and running: 
 sudo gainroot
 apt-get install openssh

You will be asked for your new root password. /*TODO: Change PW hash to enable passwords > 8 chars */

  • Finally launch xterm and run 
 ifconfig wlan0
  • Write down the IP address - from now on you can use the SSH client of your choice to connect to your favorite pocket computer - enjoy!

Upgrade to CSSU-thumb

What's CSSU?

What's thumb2 ISA?

File:info.png cssu-thumb contains a kernel based on kp51r1, therefore you automatically benefit from all kernel-power features (undervolting, overclocking, framebuffer, ...). See Kernel Power Wiki and Kernel Power 51r1 on tmo

Repositories

Disable extras-testing - it will be replaced by its thump-compiled counterpart from the CSSU repository. Make sure Nokia and Maemo Extras repositories are enabled though.

To avoid thumb-compiled binaries being overwritten by upgrades from non-thumb repositories use the following /etc/apt/preferences file 

 Package: *
 Pin: release a=community-thumb
 Pin-Priority: 700             
                
 Package: *       
 Pin: release a=Extras-devel-light
 Pin-Priority: 500                
                
 Package: *       
 Pin: release l=Extras
 Pin-Priority: 550    
                
 Package: *       
 Pin: release l=community-testing
 Pin-Priority: 600

Installing CSSU-Thumb

  • Launch community SSU from applications menu.
  • Install the proposed updates.

Essential software packages

The following is a list of applications which (IMHO) constitute a reasonable base set 

apt-get install backupmenu busybox-power cryptsetup tracker-extractor-vorbis rawcam gstreamer0.10-plugins-good-extra-formats xournal filebox fm-boost fmradio recaller swappolube tracker-cfg flashlight-extra-gtk vim flashlight-applet cal-home-widget adflashblock-css kernel-power-settings cssufeatures catoriseplus ttf-nokiapure mce-ledpattern

Install non-optified cryptsetup 

 wget http://maemo.merlin1991.at/apt-mirror/extras-devel/pool/fremantle/free/c/cryptsetup/cryptsetup_1.0.4%2bsvn26-3_armel.deb
 dpkg -i cryptsetup_1.0.4%2bsvn26-3_armel.deb
 echo "cryptsetup hold" | dpkg --set-selections

Install & configure bootloader 

 apt-get install u-boot-flasher kernel-cssu-bootimg
 ln -s /etc/bootmenu.d/20-Maemo5-kernel-cssu-2.6.28.10-cssu3.item /etc/default/bootmenu.item
 u-boot-update-bootmenu

USB Host mode

Host mode announcement 

 wget http://atrey.karlin.mff.cuni.cz/~pali/usbmode/usbmode_1.0-3_armel.deb
 dpkg -i usbmode_1.0-3_armel.deb
  • USB mode can be set through the status menu
  • To connect USB peripherals use a USB A-to-A adapter

Configure openmediaplayer

OMP Wiki 

dpkg -i openmediaplayer_20121220-1+thumb0_armel.deb
  • As root, edit file:
/usr/share/dbus-1/services/com.nokia.mediaplayer.service

so the line: 

Exec=/usr/bin/mediaplayer

...becomes: 

Exec=/usr/bin/openmediaplayer

This will replace execution of MP binary with OMP one - without physically replacing files, so you can revert back to MP by reverting changes.

  • tracker-cfg

/* TODO */

Faking Flash Player 12

Flash Player on tmo 

apt-get remove --purge adobe-flashplayer
apt-get install hexedit
dpkg -i adobe-flashplayer-10.deb
hexedit /usr/lib/browser/plugins/libflashplayer.so
  • Once in Hexedit, press CTRL+S and type in 31302e31 and press enter, the string you've just found need to be changed to 31322e31
  • Now, press CTRL+S, type "y" and search for 31302c31 and change it to 31322c31
  • Press CTRL+S then "y" again.
  • Close terminal and enjoy new faked v12.1.98.88 flash player

Tweaks

Kernel Power Settings

To enable overclocking (more horsepower) and undervolting (less power consumption) run the following commands 

kernel-config save stock
kernel-config load ideal
kernel-config default ideal

To revert to stock settings run 

kernel-config load stock
kernel-config default stock

swappolube

Config details

cssu-features

  • Launch cssu-features from the applications menu
  • On first run choose "Fix config"
  • Launch cssu-features again
  • Configure to your taste

Theme customizer

  • Set nokia-pure as default font

Disable Nokia Hands

  • Edit the file
/etc/hildon-welcome.d/default.conf 
[hildon-welcome]
filename=Hands-v32-h264.avi
  • Comment out the last line or specify gstreamer compatible movie file

Backup your device

  • Reboot with keyboard open
  • Select default kernel
  • In backupmenu press 'b' to start backup
  • Press 'q' to backup both rootfs and optfs
  • Select 'p' twice to store backup on /home/user/MyDocs
  • Wait for backup to finish
  • Connect USB to Linux box
  • Press 'w' to export eMMC as mass storage device
  • On your Linux box check 'dmesg' to identify device names (e.g. /dev/sdX), mount /dev/sdX1, switch to the mount point (e.g. /media/usb) and run 
tar -cf /home/user/MyDocs_backup.tar

Adjust eMMC partitioning

/* TODO: Evaluate better filesystems and possibly alignment */

  • With eMMC still exported as mass storage device using backupmenu point your favorite partition manager to /dev/sdX
  • Adjust partitions to your needs (align to MiB, not cylinders), for example 
 dev         size       fs    mountpoint
 mmcblk0p1   24576MiB   vfat  /home/user/MyDocs
 mmcblk0p2    5120MiB   ext2  /home
 mmcblk0p3     835MiB   swap

It's recommended to leave /dev/mmcblk0p1 as vfat for /home/user/MyDocs as it needs less tweaks to maemos mmc-scripts. For other options visit repartitioning the flash

Disk Encryption

/* TODO: Verify that HW accel is being used */ /* TODO: Use initrd in NAND and encrypt rootfs */

Preparing userland

File:warning.png Don't reboot your device before having performed all steps described in this chapter or else you'll have to reflash your phone!

  • Make sure cryptsetup and busybox-power packages are installed to rootfs 
dpkg -L <pkgname>

scp rcS root@<n900-ip-addr>:/etc/init.d/
scp rcS-late root@<n900-ip-addr>:/etc/event.d/
  • Edit the file
/sbin/preinit

and insert the command modprobe fbcon as the last line in function init_system() (just above the })

  • Get an n900 keymap and convert it (on your Linux box): 
loadkeys -b nokia-n900.map > nokia-n900.kmap
  • Copy the keymap to your phone's root directory 
scp nokia-n900.kmap root@<n900-ip-addr>:/
  • Create /etc/default/osso-mmc-blacklist.sh and corresponding /etc/default/osso-mmc-blacklist containing devices which should not be mounted to MyDocs - /dev/dm-0 and /dev/dm-1)

Edit the files

/usr/sbin/osso-usb-mass-storage-enable.sh and :/usr/sbin/osso-usb-mass-storage-disable.sh

and add the following lines at the beginning 

case $1 in
  /dev/dm-*)
    set /dev/mmcblk0p1
    ;;
esac

Move optfs to encrypted partition

  • On your Linux box extract the :optfs.tar file from the previously created MyDocs backup 
 cd /tmp
 tar -xf ~/backups/MyDocs_backup.tar
  • Boot your phone into boot manager and export eMMC to USB. On your linux box run the following commands to create an encrypted ext3 filesystem on mmcblk0p2 
cryptsetup luksFormat /dev/sdX2      # Confirm by typing YES, specify a looong passphrase
cryptsetup luksOpen /dev/sdX2 n900
mkfs.ext3 /dev/mapper/n900
  • Now you can restore your optfs backup to the encrypted partition 
mount /dev/mapper/n900 /mnt
