This update brings all the AOSP Android 4.2.1 functions and features, such as the new Lockscreen layout, 360 degrees panorama for the Camera app, new Swype-like keyboard, improved Google Now service, Quick Settings notifications panel and many many others. You can test all these features by using your own Galaxy S I9000 device.
Note that before you can move to the tutorial, you should know that this is currently the first build of CyanogenMod 10.1 Nightlies and it might have some bugs and errors while running it. I’ve tested this very first build and it seems like some Google applications aren’t fully supported by the new ROM. That’s is why you should read the preparation guidelines to learn how to successfully flash this update and create a full NANDROID backup of the currently installed ROM.
Install this CM10.1 Nightly ROM only on the Samsung Galaxy S I9000 smartphone. Do not attempt to flash these files on any other variants of Galaxy S.
It would be better if you’d use these updating files on a secondary smartphone and not on your day-to-day device. Also, to successfully complete the installation, it would be better if an advanced Android user would use this post. Do not try to update your phone if you’re a novice as you might end up bricking the phone.
Create a full NANDROID backup of the currently installed ROM. Remember that this new CM 10.1 update has some bugs and not all functions of Android 4.2.1 will work. That is why you should set a restore point for your phone.
Your Galaxy S I9000 should be rooted and running the CWM Recovery image.
This is a guide for advanced Android users and you should only use the new ROM for testing of the new Android 4.2.1 Jelly Bean.
Enable USB debugging option from your device’s Development Menu. NOTE: When you update to Android 4.2.x, you will notice that the ‘Developer options’ menu is not shown and you will have to open Settings, then ‘About phone’ and then scroll down until you reach the ‘Build number’ section and, you have to tap on it 7 times to re-enable the Developer Options. Return to the first menu of Settings and you should find that option listed there.
Charge the phone’s battery installing the new ROM. You have to prevent it from powering off during the installation of CM 10.1 Nightly build.
Read the entire tutorial and if you cannot complete the update, then you should ask for more help in comments.
These were all the guidelines you had to read and now you should move to the next part of this post.
How to install Official CM 10.1 Nightlies on Samsung Galaxy S I9000:
Download the latest CM10.1 Nightly build from HERE. Save the ROM zip file on your Desktop screen.
Get the latest Google Apps zip for CM 10.1 and Android 4.2.1 from HERE. Don’t download any old file as that won’t work with this Jelly Bean-based ROM. Don’t extract the contents of the zip and leave the file where you’ve placed the ROM zip.
Now, connect your smartphone to your PC using the USB cable. Move both zip files on its internal SD card and don’t extract their contents. Unplug the phone from PC when the transfer is complete.
Power off the Galaxy S device. Boot it into CWM Recovery mode by pressing at the same time ‘volume up’, ‘home’ and ‘power’ buttons at the same time. Release the buttons when the screen flickers.
When you’re at the main ClockworkMod selection menu you can choose to create a ‘backup’ of the ROM. If you already created such backup before moving to this tutorial, then you should skip this step.
First thing that you need to select is ‘wipe data/ factory reset’. Confirm this process. This won’t delete the contents stored on the internal SD card. NOTE: all applications, SMS and other data on the /system partition will be deleted. When the data wiping process is complete you should return to the main recovery menu.
Select ‘install zip from sdcard’ and then ‘choose zip from sdcard’. Find the CM 10.1 Nightly ROM zip and confirm that you wish to install it.
When the ROM is installed you need to select again ‘choose zip from sdcard’ option again. Find the Gapps zip file and confirm its installation.
After all the zip files files have been installed, you can return to the main menu of CWM Recovery.
Select ‘reboot system now’.
The Galaxy S will now perform its first boot process with this new CM10.1 Nightly ROM. This shouldn’t take more than 5 minutes.
Enter the Google Account for your phone and then you’re free to start testing its new ROM.
Use this ROM and tell us in comments if you find any errors. Also tell us which new functions you like the most.
NOTE: In case the CM 10.1 Nightly doesn’t install at your first attempt, then you should repeat the entire tutorial once again. Eventually you should be able to complete the install.
To keep your device updated with the latest version of CM10.1 Nightlies build, you will have to return to this post or you can choose to update from the ‘About phone’ section, where you will find the CyanogenMod Updates option. I think that these are all the instructions that you had to follow and now you should begin testing it.
