As you know, Google and Samsung announced last October in Hong Kong what was already an open secret: the launch of the new Galaxy Nexus , the first handset to feature the new version of Android, Ice Cream Sandwich .
A few days later, Google released an update to the Android SDK beta including Android 4.0 to developers to gradually adapt their applications to the new system because it includes some improvements to unify the development of the interface for smartphones and tablets. Well, as we discussed in the article where you said that, sadly, the Nexus One will run out of Ice Cream Sandwich officially , the Nexus S is already getting its share, in this case as a port of the beta included in Development Kit released by Google.
The "guilty" of such a feat are releasing new versions every day more and more of the existing port, and although I must say that at first it was hard to think of this as a version for everyday use, it is true that the improvements that have been incorporated, and which will continue to work, have made it a viable option for the impatient who do not we can wait until the new version of Android is officially released for the Nexus S, presumably a few weeks after the launch of Galaxy nexu s-available starting November 17.
Installing the ICS port on Nexus S
Look at the last pages of this thread of XDA the latest version and download it
Follow this tutorial to teach you from scratch, step by step what you must do (no need to perform step 4.
Before the tutorial:
Copy everything you have in the SD as unlocking the phone will delete everything you have into it.
The steps of the tutorial has been tested on a Nexus S i9023 (SC-LCD) with Android 2.3.4 (original).
To determine the version of your Nexus S go to Settings / About phone and watch the first 4 characters that appear in the baseband information. In my case: I9023 XXKD1.
1. Install drivers for Windows Nexus S
The first thing you have to do is install the Android SDK that you can lose http://developer.android.com/sdk/index.html
When iniciéis first, if you will not have to install all the packages of all versions of Android (not required for this tutorial) click Cancel in the first message I will. Then, go to Available packages> Third party Add-ons> Google Inc. Select USB Driver Google package and make click Install Selected.
[NEXT STEPS ONLY TO HOLDERS OF NEXUS S i9023]
Inside the folder where you installed the Android SDK, go to the directory extrasgoogleusb_driver
Open the file android_winusb.inf and both in the [Google.NTx86] as in [Google.NTamd64] add the following:
;
;Google Nexus S GT-i9023
%SingleAdbInterface% = USB_Install, USBVID_18D1&PID_4E20
[CONTINUES THE TUTORIAL FOR ALL VERSIONS]
Now turn the Nexus S. Connect the USB cable from your phone to your PC and turning it on down the keys left and the Volume Up button, this will start in Bootloader mode Interface.
If you do the first time that the Nexus S ROOT and have never played anything like this on the phone, in paragraph LOCK LOCKED STATE will tell.
Now, without touching anything on the phone Make sure that Windows has not made a mistake when installing the drivers from the Nexus S, in any case id to Device Manager, you give it to you choose Update Driver, and NOT find the driver on Windows Update, to install it from a specific location on the next screen that you will Marcais the Search for the best driver in these locations (be sure to only checked the Include this location in the search) and search directory you choose as the folder extrasgoogleusb_driver.
Click Next and if you install it as Android ADB Interface all be gone, if not, go back and choose the option will choose the driver from a list, if you Android ADB Interface appears as an option to choose, go on and install it, if not, click on Have Disk and seek him in the above directory (extrasgoogleusb_driver).
2. Unlock the Nexus S
From Windows Open a terminal prompt (Start / Run: cmd) and go to the tools directory in the directory where you may have installed the Android SDK, in my case the command would be:
cd "C:Archivos de programaAndroidandroid-sdktools"
Once there, execute the following command:
fastboot oem unlock
I see a screen with a number of conditions and two options to choose Yes wiggle with the volume keys and selected with the button. NOTE: This will erase all information from your phone and SD card, so be careful with the data loss.
When done you should show in paragraph LOCK UNLOCK STATE.
3. Flashing a recovery
Once the tedious steps of the tutorial, we turn to the fun part. The good news here is that the Nexus S eliminates the recovery on every restart of the terminal, making it very difficult to accidentally bricking.
To begin recovery of ClockworkMod download from this link http://forum.xda-developers.com/showthread.php?t=988686 (serves both i9020 and i9023 i9020A to) once downloaded to the Tools directory copiadlo your Android SDK installation (in my case "C: programaAndroidandroid-sdktools Files") and as recovery.img renombradlo.
We will again use the terminal commands, so you had Open it if not already open (Start / Run: cmd).
We are located in the corresponding directory:
cd "C:Archivos de programaAndroidandroid-sdktools"
And flash the recovery with:
fastboot flash recovery recovery.img
Once finished choose from the Nexus S Bootloader Reboot option (no dry pulséis Reboot to restart in Android because you crush the recovery and you have just put the factory).
NOTE: If instead of telling you that gives you complete successfully an error is that the file is corrupted, so download the file. Img again.
Now we have to decide what we do with our Nexus S, if we simply have access to features that require ROOT or if, on the contrary, we want to install a custom ROM. In both cases the procedure is the same, but changed files to use, so I will detail in two separate sections.
4. [OPTION 1] ROOT Access
After restarting the phone Bootloader Reboot option, you go down with the volume keys until the option You select Recovery and the power button. This will start the recovery you have just installed.
To access ROOT file should be placed in the external storage of the phone, so first of all you must download the following file your-2.3.6.1-ef-signed.zip .
Once downloaded, accessed from the storage and recovery at Mounts and from there you choose the storage option USB Mount, which will mount the device on the PC as if it were a USB memory.
Then copy the downloaded file (unpacked) directly into the root of the SD, when copying is complete, eject the storage from the icon next to the clock and you choose Unmount from the recovery. This last step (the recovery) will be returned to the screen Mounts and storage, where it is important to remove all partitions appear, ie, all bearing the Mount option (which indicates that they are removed).
Once this check you return back to main menu Go back and you choose the option Install from sdcard zip, within this zip Choose from sdcard you choose and you sail with the volume keys to the file your-2.3.6.1-ef- signed.zip, you must install by clicking on the button and choosing, then the Yes option.
When you complete your installation will display the message Install from sdcard complete. Now you can click Go back to the main menu and reboot to reboot system.
When iniciéis Android and will have access and superuser ROOT installed.
NOTE: You can check if you are ROOT in several ways:
ADB.
Installing Terminal Emulator on the phone.
Checking if applications get access ROOT.
5. [OPTION 2] Install custom ROM
After restarting the phone Bootloader Reboot option, you go down with the volume keys until the option You select Recovery and the power button. This will start the recovery you have just installed.
Now you will have to choose which ROM you are going to install on your Nexus S, my main recommendations are CyanogenMod and MIUI (the latter remember to download the language pack unless you want it come out in Chinese and the first download the Google Apps).
After downloading the file for the ROM you want to install, accessible from the storage and recovery at Mounts and from there you choose the storage option USB Mount, which will mount the device on the PC as if it were a USB memory.
Then copy the downloaded file (unpacked) directly into the root of the SD, when copying is complete, eject the storage from the icon next to the clock and you choose Unmount from the recovery.
Once you turn removed the storage back to the main menu Go back and do a Wipe both the Dalvik cache partition as / data and / cache (if any) for it, from the main menu you choose Wipe recovery and You select this option within each of the options mentioned for the wipes. This step is done to avoid incompatibilities between data ROMs having a ROM system to another.
This done you return to the main screen you choose Go back and zip Install option from sdcard, within this zip Choose from sdcard you choose and you sail with the volume keys to the file that you have previously downloaded, you must install where clicking on the button and choosing, then the Yes option.
When you complete your installation will display the message Install from sdcard complete. If any other zip ROM includes secondary (as a language pack MIUI, or Google Apps CyanogenMod necessary, you can install it by repeating the previous step).
Now you can click Go back to the main menu and reboot to reboot system.
When reiniciate and will have your favorite custom ROM installed.
