My basic setup of CyanogenMod-6.0 on HTC Desire

Since I bought my HTC Desire I want to put on it CyanogenMod. This ROM is quite popular, but only version 6.0 released last week supports HTC Desire.

I'm going to put there few notes how I did "post installation" changes like removing some programs, ssh key config, OpenVPN setup and few more.

I don't want to describe here how to install this ROM to the HTC Desire, because there is nice how-to on their pages: http://wiki.cyanogenmod.com/index.php?title=Full_Update_Guide_-_HTC_Desire

Just one remark - If you suffer with signal lost please look at this page: http://forum.cyanogenmod.com/topic/5437-signal-drops-after-rc2-final/

Put ssh keys to the phone and start dropbear (SSH server):
(taken from http://wiki.cyanogenmod.com/index.php?title=Howto:_Connect_to_Device_with_SSH)

Copy your ssh public key from your linux box to the phone:
adb push /home/ruzickap/.ssh/id_rsa.pub /sdcard/authorized_keys

Prepare dropbear on the phone:
adb shell

mkdir -p /data/dropbear/.ssh/

dropbearkey -t rsa -f /data/dropbear/dropbear_rsa_host_key
dropbearkey -t dss -f /data/dropbear/dropbear_dss_host_key

cp /sdcard/authorized_keys /data/dropbear/.ssh/

chmod 755 /data/dropbear /data/dropbear/.ssh
chmod 644 /data/dropbear/dropbear*host_key /data/dropbear/.ssh/authorized_keys

echo "export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/system/sbin:/system/bin:/system/xbin:/system/xbin/bb:/data/local/bin" >>/data/dropbear/.profile

dropbear

Remove some useless applications:
(check this page http://wiki.cyanogenmod.com/index.php?title=Barebones to see what can be removed)

Reboot to "ClockworkMod recovery" using these steps: http://android.modaco.com/content/htc-desire-desire-modaco-com/310794/fake-flash-by-koush-launching-recovery-on-your-device-without-a-pc/

Mount /system partition:
adb shell
mount -o nodev,noatime,nodiratime -t yaffs2 /dev/block/mtdblock3 /system
mount /data

Backup directories under /data:
BACKUP_DESTINATION="/sdcard/mybackup"
cd /data
mkdir -p $BACKUP_DESTINATION/data/ && \
cp -R `ls /data | egrep -v "dalvik-cache|lost\+found"` $BACKUP_DESTINATION/data/

Move applications to sdcard:
for APK in ApplicationsProvider.apk CarHomeGoogle.apk CarHomeLauncher.apk com.amazon.mp3.apk Development.apk Email.apk Facebook.apk GenieWidget.apk googlevoice.apk Maps.apk PicoTts.apk Protips.apk RomManager.apk SetupWizard.apk SpeechRecorder.apk Stk.apk Street.apk Talk.apk TtsService.apk Twitter.apk VoiceDialer.apk YouTube.apk; do
echo "*** $APK"
mkdir $BACKUP_DESTINATION/$APK && \
mv /system/app/$APK $BACKUP_DESTINATION/$APK/ && \
mv /data/data/`awk -F \" '/'$APK'/ { print $2 }' /data/system/packages.xml` $BACKUP_DESTINATION/$APK/
#/system/bin/pm uninstall `awk -F \" '/'package.apk'/ { print $2 }' /data/system/packages.xml`
done

Remove unused audio files:
for AUDIO in `find /system/media/audio -type f|egrep -v "ui|Alarm_Buzzer.ogg|SpaceSeed.ogg|Doink.ogg|SpaceSeed.ogg|CrayonRock.ogg"`; do
for AUDIO in `find /system/media/audio -type f|egrep -v "ui|pixiedust.ogg"`; do
    echo "*** Removing $AUDIO"
    rm $AUDIO
done

Unmount all used filesystems:
cd /
umount /data /sdcard /system

It's all for now... I'm sure I will do more sooner or later, but it's just a few notes for now.

Enjoy :-)
