Restoring factory ROM

  • 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

Sources:

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

  • host: fastboot oem unlock

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

On the host, example how to solve permissions:
Create /etc/udev/rules.d/99-android.rules for Nexus phones: 

SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bb4", ATTRS{idProduct}=="0fff", MODE="0666", OWNER="<your_account>" # Nexus One Fastboot
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e11", MODE="0666", OWNER="<your_account>" # Nexus One Normal
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e12", MODE="0666", OWNER="<your_account>" # Nexus One Debug/Recovery
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e20", MODE="0666", OWNER="<your_account>" # Nexus S Fastboot
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e21", MODE="0666", OWNER="<your_account>" # Nexus S Normal
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e22", MODE="0666", OWNER="<your_account>" # Nexus S Debug/Recovery
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e23", MODE="0666", OWNER="<your_account>" # ???
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4e24", MODE="0666", OWNER="<your_account>" # Nexus S USB tethering

Then execute /etc/init.d/udev reload

Some examples:

  • adb devices
  • adb shell
  • adb logcat

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

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.
