Install CM 10.2 Nightly ROM for the Samsung Galaxy

Now you can install an Android 4.3 custom ROM for the first gen Galaxy S device using an Unofficial Build of CM 10.2. Read this entire post and you should be able to flash all required files at your first attempt.

The Android 4.3 update has been released officially for Nexus 4, 7, 10 and for the Google Play Editions of the HTC One and Samsung Galaxy S4, while the Galaxy S I9000 model won’t receive it. However, an XDA member and developer managed to compile a custom build of CM 10.2 and allow Galaxy S users to flash a custom Android 4.3 for their devices. Use the tutorial only if you’re an advanced user.

This build of CM 10.2 contains new features and multiple improvements that should allow you to experience the latest Jelly Bean 4.3 functions right on your Galaxy S. In order to successfully install it on your device, you will need to take a look at the guidelines below first. Here’s what you need to know:

  • This is a tutorial that works only with the Samsung Galaxy S model number I9000.
  • Do not attempt to update any other device using the files listed in this post.
  • The Galaxy S that you are about to updat has to be factory unlocked, it should be rooted and running a custom Recovery image such as CWM or TWRP.
  • In the tutorial you will find a step that asks you to ‘wipe data’ and ‘factory reset’ the device. This will delete the contents stored on your phone’s system partition. Files such as installed apps data, SMS and similar ones will be deleted.
  • The internal storage won’t be deleted by the Factory Reset.
  • If you want to backup SMS, call logs info and APN Internet Settings, then you can use this utilities for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access will be required for some of them.
  • Sync Contacts info with your Gmail account with this tutorial here.
  • USB Debugging should be enabled in Developer Options menu.
  • Make sure that your phone’s battery has enough power left before switching off completely. If the device powers off in the middle of the updating process, then you will be forced to repeat the entire tutorial once again.
  • Read this entire post and make sure not to skip any steps.
  • Note that this is a tutorial that should be applied by an advanced user. Do not blame us in case your lose any important data or you brick the smartphone.
  • If you cannot complete the update, then you can always use the comments field to ask for extra guidance.

Now that you know all that, continue to the tutorial and learn how to update your device. Note that this custom ROM might pack some bugs as not all functions will work properly. That is why you should only install it if you want to test CyanogenMod latest build based on the latest Jelly Bean ROM update.

How to flash CM 10.2 Unofficial ROM based on Android 4.3 for Samsung Galaxy S I9000:

  1. Download the CM 10.2 Unofficial build from here.
  2. Download Gapps for this custom ROM from here.
  3. Connect the smartphone with your PC via USB Cable.
  4. Now move both files to your Galaxy S internal storage. Don’t unzip the files.
  5. After the transfer is complete, disconnect the device from computer.
  6. Power off the device and boot it into CWM / TWRP Recovery.
  7. First you need to create a full NANDROID backup of your currently installed ROM:
    > CWM Recovery: select ‘backup and restore’ option, then confirm the process.
    > TWRP Recovery: press Backup, select the system files you wish to backup and then confirm.
  8. Now you can apply ‘factory reset':
    > CWM Recovery: select the ‘wipe data/ factory reset’ option. Confirm.
    > TWRP Recovery: press Wipe, then Factory Reset. Confirm this process.
    – when the data is wiped successfully you can continue to the next step.
  9. Install the custom ROM:
    > CWM Recovery: select ‘install zip from sdcard’, then ‘choose zip from sdcard’. Browse the phone and load the CM 10.2 unofficial zip. Confirm the installation.
    > TWRP Recovery: press Install, then find the CM 10.2 Unofficial zip file. Confirm that you wish to install it by sliding to the right the blue button shown at the bottom of the Recovery screen.
    – wait several minutes for the installation to complete without pressing any buttons.
  10. Now that the ROM has been installed, repeat step 9 and flash the Gapps zip. Confirm.
  11. After both the CM 10.2 ROM and Gapps files are successfully installed, you should return to the main Custom Recovery menu.
  12. Reboot your smartphone by selecting ‘reboot system now’ option for CWM, while for TWRP you need to press ‘Reboot’, then ‘System’.
  13. Wait until the ROM completes the first boot process. Take control over your device when the home screen of the CM 10.2 ROM appears.
  14. Test the ROM and try to compare it with your previous OS.

I think that these were all the steps you had to follow and that now you’re free to test the new CyanogenMod 10.2 Unofficial ROM. Note that the battery life of your device might suffer after the installation, as this new Jelly Bean 4.3 custom build will require lots of memory.

If didn’t manage to complete the tutorial and you got stuck, then you can ask for more help in comments or you can try to repeat the entire tutorial once again.

If you don’t like how the CM 10.2 Jelly Bean 4.3 Unofficial ROM works with your Galaxy S I9000, then you can use the backup file created in step 7 to restore it to its previous OS. Use the same Custom Recovery mode to apply the ‘restore process’.

    well, I’m waiting for my mobile to re-start.. after doing everything like it’s written here, I think it’s stuck on the part where it has a little circle with cyanogenMod written on the middle of it and that little circular line spinning.. It’s been like this for at least 10 minutes.. Is it normal?
