Then execute /etc/init.d/udev reload
Restoring factory ROM
Warning, it will destroy everything, make your backups first!!
- Get firmware here for a European Nexus S i9023, mine needs the I9023XXKB3 one.
- Rename tar.md5 as tar
- Get Odin sw from here, choose i9023
- e.g. I9003_Odin3_v1.82.rar & SAMSUNG_USB.rar
- Run Odin (works in a virtualbox if needed), load the 4 files:
- bootloader: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/Bootloader_I9023XXKA3.tar
- PDA: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar
- Phone: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/MODEM_I9023XXKB3_REV_00_CL912571_SIGNED.tar
- CSC: I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/DGS_I9023_EUR.tar
- Turn phone off
- Plug USB
- Just before battery icon showing, enter download mode by pressing middle of volume up / volume down button for long, you'll get a big yellow warning triangle
- If using virtualbox, bring USB device (Samsung serial) to virtualbox
- Now Odin should show a yellow rectangle with COM0
- Press "start" in Odin

Restoring (most of) factory ROM with fastboot
Ok previous section was about restoring *everything* as genuine but it requires Windows and most of the time all you screwed up was the boot image, the recovery image or the system image so here is how to restore them or part of them provided that you can still enter fastboot:
fastboot oem unlock # if needed fastboot flash recovery recovery.img # from Samsung PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar fastboot flash system system.img # from Samsung PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar fastboot flash boot boot.img # from Samsung PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar
Warning: I got /sdcard content erased, maybe because I tried to enter the native recovery, but anyway, make backups first before trying anything you risk regretting!!!
E.g. to make a backup with clockwordmod:
- Put phone into fastboot mode
- Enter recovery
- Choose backup & restore / backup
- Choose mount / mount USB storage
- From host: copy clockwordmod/backup/*
Entering fastboot mode
- Power off phone
- Press Volume up and power button together for long
- You've entered fastboot
- Alternatively, fastboot can be triggererd from adb: adb reboot-bootloader
For getting fastboot on the host, see further below
Rooting
- copy su-2.3.6.1-ef-signed.zip (from http://forum.xda-developers.com/showthread.php?t=682828) on USB storage
- enter fastboot mode (see above)
- host: fastboot oem unlock
- fastboot flash recovery 3025-i9023.img
!! Don't touch boot image or try CW 3.0.0.0, one of them caused the phone to not start android anymore, I had to perform the full factory restore with Odin !!
- enter recovery mode from fastboot
- You can make a backup now
- install zip from sdcard -> choose -> su-2.3.6.1-ef-signed.zip
- reboot

Android 2.3
Getting fastboot & Android sources
There are several binaries around but I wanted to build my own.
Maybe not the shortest way... I downloaded all android sources...
cf http://source.android.com/source/downloading.html
Some missing deps on my 64-but debian when I tried to compile everything: gperf, libc6-dev-i386, lib32ncurses5-dev ia32-libs g++-multilib lib32z1-dev lib32readline6-dev
. build/envsetup.sh lunch crespo-eng make -j2
Maybe we can just compile adb & fastboot:
make adb make fastboot
cf http://www.cduce.org/~abate/build-android-adb-debian-sid-amd64
Getting adb & Android SDK
Get it from http://developer.android.com/sdk/index.html
Run tools/android -> get Android SDK Platform-tools, revision 3
It brings also adb but not fastboot
If you want to update SDK: tools/android update sdk
adb
You need to activate USB debugging:
- Settings > Applications > Development > USB debugging
Some examples:
- adb devices
- adb shell
- adb logcat
adb as root
Once the phone is rooted, you can, from a shell with e.g. adb shell invoke "su" & get root.
But to get immediately into root, the file /default.prop needs to contain ro.secure=0
But that file is restored from boot.img at each boot so you need to modify that one
See http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack%2C_Edit%2C_and_Re-Pack_Boot_Images#Alternative_Method
but there is also abootimg in debian:
- Taking the boot.img from Samsung (see above in I9023_EUR_GRI54_XXKB3/I9023_EUR_GRI54_XXKB3/PDA_SOJU_GRI54_TMO_EUR_MR1_SIGNED.tar). I tried also with a boot.img taken by CW backup but the modified version was apparently too big to be flashed back. Anyway CW backup version is orig boot.img extended to the physical partition size (8M)
abootimg -x boot.img mkdir ramdisk cd ramdisk gzip -dc ../initrd.img | cpio -i sed -i default.prop 's/ro.secure=1/ro.secure=0/' find . -print|cpio -o -Hnewc|gzip > ../initrd.img2 cd .. abootimg -u boot.img -r initrd.img2 fastboot flash boot boot.img
For the last command, the phone needs of course to be in fastboot mode
Reboot phone
I had to re-enable USB debugging but now adb shell brings me immediately a root shell :)
Without this setup, it's a bit cumbersome to automate root commands from host, it looks like
adb shell su -c "netcfg usb0 dhcp"
and the SuperUser app prompts you for confirmation on the phone for each new command
Screenshots
Run ddms (from SDK) -> Tools / Device / Screen capture
USB tethering
Plug phone & PC via USB
Activate USB tethering (Settings / Wireless & networks / Tethering / USB Tethering)
It works OOB on Debian, nothing to do
Getting busybox
Need rooted phone, see above
Google's stripped busybox, called toolbox, is far from enough once you get a shell on the phone
- Get Busybox Installer from Market
Examples to use busybox versions instead of toolbox versions when the command exists twice:
# busybox mount -o remount,rw /system # /system/xbin/mount -o remount,rw /system
Wi-Fi & client certs
To be able to authenticate to a Wi-Fi network using client certificates via TLS:
If needed, export certificate from IE in Pkcs#12 PFX, *with* private key, *with* all certs, *without* strong enc, *without* deletion of private key.
Rename .pfx file as .p12
(source: http://www.google.com/support/mobile/bin/answer.py?answer=168466&topic=27214#1086573)
Copy pkcs#12 certificate to root of USB storage.
File must end with .p12, not .pfx!
One single file with key+cert+cacerts is ok
Wi-Fi params: 802.1x EAP / TLS / phase2: None / CA cert: cf previous import / user cert: idem / Identity: DOMAIN\user... / Anonymous id: empty / password:...
Importing CA certs
I could only manage it via a webserver & crafted headers:
<?php header("Content-Type: application/x-x509-ca-cert"); ?> -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----
You may try this free service: http://www.realmb.com/droidCert/ which seems to do the same.
But even if imported they seem not to be used e.g. for IMAP TLS.
There is a heavier procedure to include CA certs in the phone root list, see CACert wiki, not tried yet.

From this post:
Create your own maps with Mobile Atlas Creator (Java-based) & use them e.g. with RMaps, AndNav, Maverick, TrekBuddy,... (bitmaps so ok only for small areas such as cities)
- Get e.g. RMaps from Android Market
- Get latest release of Mobile Atlas Creator & unzip it
- Get latest SqliteJDBC library and copy it inside th eMobile Atlas Creator directory
- Run it (start.sh)
- Choose your source, e.g. OpenStreetMaps, Google Maps,...
- Select area: Right click to Drag, Scroll to zoom In/Out, Left click to select downloadable area
- Select one or more zoom levels, e.g. from 12 to 18 for all levels of details of a city
- Do “add selection” with a name of your choice
- Select “BigPlanet SQLite” from “Atlas Settings” (for RMaps, otherwise Maverick Atlas Format for Maverick etc)
- "Create Atlas"
- Download the .sqlitedb map into the phone SDcard/rmaps/maps
- Disconnect the phone
- Open RMaps and Menu > More > Settings > User defined maps > BigPlanet_maps.sqlitedb > Enabled Maps
- Return to main maps screen and then Menu > Maps > BigPlanet_maps.sqlitedb.
