Here is a list of commands, taken from below, that should install CyanogenMod? and Debian and set some things up. This page is a less verbose version of some of the instructions on the page g1_debian_cyanogenMod.
Most explanation, acknowledgments, choices, and instructions for making backups, have been omitted from the quick instructions, so if you are unsure, or encounter problems, or want to see the acknowledgements/hyperlinks, then you may want to refer to the more verbose instructions. If you want Debian without CyanogenMod?, refer to the verbose instructions.
These instructions may or may not work for other Android phones. I'm not sure but I'm guessing that they will only have to be modified a little bit for other Android phones which have a USB cable, for instance, maybe /dev/block/mmcblk0p2 and /mnt/dev/block/\/vold/179\:1 have to be replaced by something else. If your phone isn't yet rooted, I don't know much about how to/if you can root it, but see here: http://forum.xda-developers.com/showthread.php?t=442480 (I think links that page may be G1 specific; but presumably there are other such guides for other devices; search Google for the word "root" plus the name of your phone).
Most of these instructions were written down after the fact, so they may not be correct or complete. I'd recommend reading through a given section before you follow the instructions in that section, to make sure you understand, and to make sure I didn't make a mistake and tell you to do something obviously wrong. Please tell me if you discover any errors or omissions in this document, so that I can fix it (my email is at ).
We assume your PC is running Debian GNU/Linux.
Install the android SDK from http://developer.android.com/sdk/.
The "adb" command, which interfaces with the phone over the USB cable, is in the SDK, in the "tools" subdirectory -- you might want to put it in your PATH first.
If adb ever says the device is not found, then it may be because you are running the adb daemon on your PC without root permissions (here I'm talking about root permissions with respect to your PC's operating system; not root permissions with respect to your phone). As root, do "adb kill-server" and then "adb shell". If you get into the shell, just exit. The adb daemon will stay running on your PC, but now with root permissions.
Attach the phone to the PC via the usb cable, and put the the phone into USB mass storage mode.
On the PC, as root:
aptitude install gparted gparted
Resize the first partition (it is either FAT16 or FAT32) and create a new, second partition that is ext3. I gave my ext partition about 75% of total space.
To upgrade from ext3 to ext4 (this is optional), on your PC, as root, assuming that the phone is at /dev/sdc, and that your PC currently has ext4 support:
tune2fs -O sparse_super,filetype,dir_index,has_journal,extents,uninit_bg /dev/sdc2 e2fsck -pDf /dev/sdc2 # you'll get some errors being fixed but that's apparently normal. i got some checksum invalids.
See http://forum.xda-developers.com/showthread.php?p=3915123 . Don't reboot yet.
Download the latest CyanogenMod? stable build onto your PC from http://forum.xda-developers.com/showthread.php?t=537204 . On your PC, do:
adb push update-cm-*-signed.zip /sdcard/update.zip
Rebooted the phone while holding down the Home key and the Power key until it goes into Cyanogen's recovery. From the menu, select the option to flash /sdcard/update.zip. Reboot (I think it reboots automatically).
Put the phone into USB mass storage mode.
On the PC, assuming the phone is at /dev/sdc:
mkdir /media/android-linux mount /dev/sdc2 /media/android-linux aptitude install debootstrap debootstrap --verbose --arch armel --foreign lenny /media/android-linux http://ftp.us.debian.org/debian umount /media/android-linux adb root adb shell su # now you're in the adb root shell: export mnt=/system/sd export PATH=/usr/bin:/usr/sbin:/bin:$PATH export TERM=linux export HOME=/root busybox chroot $mnt /debootstrap/debootstrap --second-stage # takes about 15 minutes echo 'deb http://ftp.us.debian.org/debian lenny main' >$mnt/etc/apt/sources.list echo 'nameserver 22.214.171.124' >$mnt/etc/resolv.conf busybox chroot $mnt /bin/bash # now you're in the chroot jail, i.e. in Debian! mount -t devpts devpts /dev/pts mount -t proc proc /proc mount -t sysfs sysfs /sys rm -f /etc/mtab ln -s /proc/mounts /etc/mtab mkdir -p /mnt/sdcard mkdir -p /mnt/system mkdir -p /mnt/data mkdir -p /mnt/dev # set the root password with: passwd root # At this point I installed the following Debian packages, also: aptitude install less emacs openssh-server openssh-client mutt offlineimap unison python awesome screen tightvncserver qiv aptitude clean
Exit out of adb shell, and (still on your PC):
adb root adb remount # remember, you may have to run this command a few times before it works cat /dev/tty > userinit.sh # or you can use a text editor #!/system/bin/sh busybox mount -t devpts devpts /system/sd/dev/pts busybox mount -t proc proc /system/sd/proc busybox mount -t sysfs sysfs /system/sd/sys busybox mount --bind /sdcard /system/sd/mnt/sdcard # for some reason /sdcard isn't working when i mount it # at boot, although i can do it later. i wonder why? # mb it isn't mounted yet at boot? busybox mount --bind /system /system/sd/mnt/system busybox mount --bind /data /system/sd/mnt/data busybox mount --bind /dev /system/sd/mnt/dev # busybox mount --bind / /system/sd/mnt/root # doesn't work busybox mount -t tmpfs tmpfs /system/sd/tmp -o noatime,mode=1777 # why burn out your sdcard with frequently updated log files, and # things that don't need to persist across boots busybox mount -t tmpfs tmpfs /system/sd/var/log -o noatime,mode=1777 busybox mount -t tmpfs tmpfs /system/sd/var/run -o noatime,mode=1777 busybox mount -t tmpfs tmpfs /system/sd/var/spool -o noatime,mode=1777 busybox mount -t tmpfs tmpfs /system/sd/var/tmp -o noatime,mode=1777 busybox chroot /system/sd /etc/init.d/ssh start busybox chroot /system/sd /etc/init.d/cron start busybox chroot /system/sd /etc/init.d/exim4 start ^D adb push userinit.sh /system/sd/userinit.sh adb shell chmod 755 /system/sd/userinit.sh cat /dev/tty > d #!/system/bin/sh export PATH=/usr/bin:/usr/sbin:/bin:$PATH export TERM=linux export HOME=/root export SHELL=/bin/bash su -c 'busybox chroot /system/sd /bin/bash' ^D adb root adb remount # remember, you may have to run this command a few times before it works adb push d /system/bin/d adb shell chmod 755 /system/bin/d
NOTE: in CyanogenMod? 4.2.14 there's a bug so you have to copy a version of busybox that has chroot, say from http://www.mwyann.com/busybox.cyanogen.chroot , move it onto your android at /data/chroot (either d/l it onto the sdcard and then move it from the shell, or use adb push. You have to chmod 775 it, too), and then change the above script to use /data/chroot rather than just chroot.
To test everything so far, reboot the phone, and then on your PC, do:
adb forward tcp:1622 tcp:22 && ssh -p 1622 root@localhost
If everything is working, you should be ssh'd into your phone (over the USB cable). For future use, You may want to put that last line in a shell script or alias on your PC.
And, to further test, on the phone, run the Terminal Emulator app. You get a prompt; enter "d"; a window will popup labeled "SU Request". You can select "Allow" or "Always Allow". Then you're back in the terminal, in Debian (you can tell you're in Debian because of the "localhost:/#" prompt).
Next, put the following at the end of your .bashrc on the phone:
And then create a file at ~/.bashrc-local on the phone containing:
mount -t vfat /mnt/dev/block//vold/179\:1 /mnt/sdcard/
To prevent man-db from making a cache, on the phone, in Debian, edit /etc/manpath.config, and uncomment the NOCACHE directive at the bottom of the file.
For passwordless logins between phone and PC, On your phone, in Debian, do the following, and enter an empty password when prompted:
ssh-keygen -t dsa
Do the same thing on your PC. Append the contents of ~/.ssh/id_dsa.pub (from your PC) to the file ~/.ssh/authorized_keys (on your phone). Append the contents of ~/.ssh/id_dsa.pub (from your phone) to the file ~/.ssh/authorized_keys (on your PC).
To create a desktop shortcut to the Debian commandline on the phone, login to root@localhost using Connectbot. Press the Home key. Long click on the desktop. Click Shortcuts. Click Connectbot. Click root@localhost.
In Debian, on the phone:
aptitude install tightvncserver
You probably also want a window manager. In Debian, on the phone:
aptitude install awesome
On the phone, in Android, install the app AndroidVNC?.
On the phone, in Debian, do the following to setup tightvncserver:
export USER=root vncserver -geometry 480x320 # (enter a password, but after that just enter "n" to decline to set a view only password) vncserver -kill :1 nano ~root/.vnc/xstartup # or use your favorite text editor
and in the text editor, comment out the line for xsession: # #/etc/X11/xsession
and add two lines to the bottom: awesome& xterm
Save and quit it.
Put the following in a script file (I put mine at "/usr/local/bin/x"):
!#/bin/sh export USER=root vncserver -geometry 480x320
To start the VNC server, run "x", on the phone, in Debian.
On the Android side, open androidVNC app, address localhost, port 5901.
On your PC, do:
aptitude install x11vnc x11vnc -storepasswd # and enter a password x11vnc -ncache 10 -rfbauth ~/.vnc/passwd
then on the phone, use Android VNC Viewer to connect to your PC, port 5900
