Install Android 4.2.2 CM 10.1 M2 for the Samsung Galaxy S Captivate

Samsung Galaxy S Captivate can now be upgraded to the latest CyanogenMod 10.1 M2 ROM using the instructions that I have posted in this article. Read the entire tutorial and make sure that you won’t skip any steps in the process so that you will be able to flash the new custom ROM at your first attempt.

This new update will bring the latest AOSP Android 4.2.2 Jelly Bean features along with all the CyanogenMod 10.1 elements. The CM 10.1 has reached its M2 build which is a more stable release than the Nightlies. In order to make sure that you successfully flash this new CM 10.1 M2 Jelly Bean 4.2.2 ROM on your Galaxy S Captivate, read the guidelines below:

  • this guide will work only with the Samsung Galaxy S Captivate. Do not try to flash this custom ROM on any other Android device.
  • the Captivate has to be rooted and running a custom Recovery image such as TWRP or CWM Recovery. We’ve used CWM recovery for this tutorial but you can use TWRP, as the instructions are very similar.
  • The tutorial will be asking you to wipe data and factory reset the device, but you can choose to skip that if your device is already on a CM10.1 build. However, if you want to be sure that the ROM won’t have any bugs then you will have to apply the ‘factory reset’ option. That will wipe the /system partition and you will lose installed apps, SMS, Call Logs and other similar data. You can choose to backup such data using the following tools: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. Root access has to be granted for some of these tools.
  • Sync your Contacts with your Gmail account so that you won’t lose any phone numbers in the process.
  • This guide is for advanced Android users and you shouldn’t blame us in case something goes wrong and you lose data or you brick the phone. There are very slim chances to brick the phone, but, still you should backup important data before installing the new CM 10.1 M2 ROM.
  • Read the entire post and make sure that you won’t skip any steps that I’ve listed below.

In case you cannot complete the installation then you should ask for help in our comments field.

How to install CM 10.1 M2 Custom ROM for the Samsung Galaxy S Captivate:

  1. Download the custom ROM zip file from HERE.
  2. Download the Gapps for Android 4.2.2 ROMs from HERE.
  3. Connect your smartphone to your PC and then move the downloaded files to your phone’s internal SDcard. Disconnect the Captivate device from PC when the files are copied successfully.
  4. Power Off the Galaxy S Captivate.
  5. Boot your device into CWM Recovery mode by pressing at the same time Volume Up, Volume Down and Power buttons. Release the buttons when the Recovery mode loads.
  6. Select the ‘backup and restore’ option to create a NANDROID backup of your current ROM. This will set a restore point for your smartphone in case something goes wrong and you can’t boot it after installing CM 10.1 M2.
  7. Select ‘wipe data/ factory reset’ option. Confirm. NOTE: If your phone is already running on a CM 10.1 build then you can skip this step and flash the new one over it.
  8. Select ‘install zip from sdcard’ and then ‘choose zip from sdcard’. Find the CM 10.1 M2 zip file and confirm the installation.
  9. When the ROM is installed then you should select ‘choose zip from sdcard’ again. Now you need to install the Gapps zip file. Confirm.
  10. Return to the main menu of the CWM Recovery mode and then select ‘reboot system now’.
  11. Wait for the first boot process to complete and then you can enter your Google Account details.
  12. Test the new CM10.1 M2 OS and tell us in comments if your device works better with it installed.

In case the first boot process takes too long to complete, then you should power off the device completely. After that you need to repeat the entire tutorial and this time you have to make sure that the step 7 actions are applied, as that might be why the new OS wasn’t installed at your first attempt. In case you have any other questions, use the comments field.

If you don’t like the new ROM then you can easily restore the previous NANDROID ROM backup using CWM Recovery mode.
