All these hacks are tested on PR1.2(!!), but the cmdlines here are just off top of my head, so maybe typos or sth can be found. Lots of it will work on PR1.3 as well, but I haven't tested anything for PR1.3 yet. "Tested" on CSSU-Tmaemo5.1 Please report on http://wiki.maemo.org/index.php?title=User_talk:Joerg_rw/tools&action=edit . Thanks!

PRIOR TO FLASHING

Remove any SIM from phone!

see below for "cherry" compulsory SMS

increase size of /home - if you like that

If you feel like those 2GB /home (and /opt) are not enough for your zillion of apps you want to install and all the files you are used to keep in your $HOME, then you may want to patch eMMC aka *VANILLA* image file for larger /home partition (/opt is a bindmount to /home/opt, so this is also a way to have more free space to install apps)

This is much easier than repartitioning the N900 *after* flashing. So if that's not obvious, this part is meant to be done on your linux desktop PC, prior to fresh full flash of N900:

NEW-HOME-SIZE=4096
# Size is in MB, tested up to 8192, changing number of chars known to 
# break things, so for 5digit values you might need more sophisticated edits.
# Theoretical limit ~28GB
sed -e "s/2048/$NEW-HOME-SIZE/" path/to/*VANILLA*.bin >patched-VANILLA.bin

the section in this image file is close to the head of file and looks like:

mmc {
        name = "internal";
        partition {
                fs_type = "vfat";
                prefix = "mydocs";
                no_create = true;
        }
        partition {
                size = 2048;
                fs_type = "ext3";
                prefix = "home";
        }
        partition {
                size = 768;
                fs_type = "swap";
        }
}

as this looks like a format free grammar, it's probably possible to "steal" whitespace from start of line to allow for 5 digit numbers . Something like:

sed -e "s/.size = 2048/size = 16192/" path/to/*VANILLA*.bin >patched-VANILLA.bin

The FLASHING

refer to http://wiki.maemo.org/Updating_the_tablet_firmware#The_Lazy_Approach

AFTER FLASHING

DO NOT install speedpatch, batterypatch, or auto-disconnect _ever_!! All three do not uninstall and do not work. AdBlock will slow down browser to a grinding halt. If you're concerned about your privacy, do not insert SIM before you read about cherry below!

Replace Nokia core repos

Nokia's repo servers are down, so the very first "update" I suggest is clicking

http://maemo.cloud-7.de/maemo5/et_al/HAM-catalogs/recommended.install

CSSU

~~Actually recent switching to PR1.3 + Community-SSU resulted in a quite similar set of system properties. So most of the things below are not needed anymore,~~ except of course the gnu sanitizing of busybox crap.

So first install CSSU! http://wiki.maemo.org/Community_SSU

You did that? Fine, let's go on...

"root" your device

open Hildon Application Manager also known as "Applications", and install rootsh - or click this link

Additional Repositories

To make the plastic case melt and burn your fingers and your cat, click http://maemo.cloud-7.de/repositories.install (includes the catalogs aka repositories test, devel, and tools. Attention, will create dups, so check your catalog list in HAM anyway. You should keep all three catalogs usually disabled in HAM! Actually test and devel are mutually exclusive when you think about it, since test is a strict subset of devel)

NEVER do an apt-get upgrade or apt-get dist-upgrade, or in HAM never click "update all" when any of these repos is enabled! - it will ruin your system

On Device

The text below in the white boxes is intended to c&p to N900 xterm, or to a ssh session to N900 on your PC (all in a root account where not mentioned otherwise - first snippet takes care of this by the first line "root"). You should highlight a whole white box or at least a whole § beginning with ####line and insert the whole text as one chunk to your N900 or ssh remote terminal.

I took care about long lines by continuation\

marks\

so don't break up a block that consists of lines ending with \

Miniwrapper for apt-get logs.

tweaks (not only) for CSSU

I currently updated to ~~16.5~~CSSU-Tmaemo5.1.

fix a bug that re-appears with each new CSSU upgrade:

apt-get install rtcom-accounts-voip-support

get rid of the time&date dialog after battery swap

sudo mv /etc/X11/Xsession.d/30osso_startup_wizard /root/

mediaplayer forgot how to play .ogg/.flac

tracker fixing index for .ogg:

sudo /var/lib/dpkg/info/decoders-support.postinst

no autorotating

To get rid of the ubiquitous autorotating while still allowing dialer to switch to portrait mode (doesn't lock microB, for now I will live with it):

gconftool-2 --set /apps/osso/hildon-desktop/ui_can_rotate -t bool false
reboot

adjust drag&drop threshold

changing the drag&drop threshold, here to "100" (makes context menus disappear on stylus-up when too small):

sed -i "s/gtk-dnd-drag-threshold = [0-9]*/gtk-dnd-drag-threshold = 100/" \
/opt/usr/share/themes/*/gtk-2.0/gtkrc && /usr/bin/hildon-theme-recache-all

If you want to highlight single chars with stylus: pen-down and move >100 pixel (to avoid popup-menu), then reduce highlighted area again by moving tip of stylus towards point where you did pen-down.

replace shaking-hands video

/etc/X11/Xsession.d/10hildon_welcome = starter for video /opt/usr/share/hildon-welcome/media/Hands-v32-h264.avi = shaking-hands-video http://maemo.cloud-7.de/maemo5/bootvideo-DONTPANIC/ (the original author please holler - I forgot your name :-/ )

#replace Hands by DONT_PANIC! bootmovie
cd /opt/usr/share/hildon-welcome/media
wget http://maemo.cloud-7.de/maemo5/bootvideo-DONTPANIC/dontpanic.avi
#cp /etc/hildon-welcome.d/default.conf \
# /etc/hildon-welcome.d/default.conf_backup #makes BOTH videos play at boot :)
## to "uninstall" simply edit the file below 
## to read  "filename=Hands-v32-h264.avi"
echo -e "[hildon-welcome]\nfilename=dontpanic.avi" >/etc/hildon-welcome.d/default.conf

backup

A job I start on my PC every day, via cron, like 'N900-rsync IroN900' (IroN900 is resolving to my N900's local IP in WLAN, via /etc/hosts. You as well can use a numerical IP). It automatically creates and keeps up-to-date a backup of N900's / (root) and /home/ (user data and opt). If my N900 is "not at home", the job will sleep until it becomes available again (I probably could handle better the rare case where I'm away for >24h, but it doesn't create too much trouble, just a bit of useless wlan traffic) For this job to work you need a working ssh-key setup that allows establishing ssh session without entering password! I.E. your PC user must have a private key in ~/.ssh/ and the matching public key must be in N900 ~root/.ssh/authorized_keys

#!/bin/sh
## call with parameter <IP of maemo device to sync>
## NB this has a path relative to $HOME of user calling the job

while ! rsync -vaRzx --fake-super root@$1:/ ~/Documents/N900/backup/$1; do 
  echo "$1 not available via ssh, retrying in 30 minutes"; 
  sleep 1800; 
done
echo "########## rootfs synced, now syncing /home"

while ! rsync -vaRzx --fake-super root@$1:/home ~/Documents/N900/backup/$1/home; do 
  echo "$1 not available via ssh, retrying in 30 minutes"; 
  sleep 1800; 
done
