Update AT&T Samsung Captivate I897 to Android 4.3 with CM10.2 custom ROM

As you know Samsung Captivate is stuck on Ice Cream Sandwich OS since Samsung declared that due to hardware limitations, the smartphone will no longer receive any OTA updates. Well, while the Captivate will no longer receive official updates, its users can still enjoy the latest features that are being included on the Android 4.3 firmware and all thanks to the CyanogenMod team. Therefore, during the following lines we will be checking on how to update the AT&T Samsung Captivate to Android 4.3 with CM10.2 custom ROM software.

CyanogenMod is a free aftermarket distribution of the Android system; the platform is not coming with stock looks and features as the devs are creating their own version of Android. That’s why, on CyanogenMod you can experience stock and extra features, apps and capabilities that are usually used for improving the speeds, optimize the performances, customize the looks, upgrade the battery life and so on. CyanogenMod is one of the most used custom ROM as the firmware is suitable with almost all the Android based handsets out there.

In our case, the Samsung Captivate will be installed with CM10.2. CM10.2 is the latest version of CyanogenMod, the update being based on Android 4.3 Jelly Bean OS. So, if you choose to apply this step by step guide you will finally be able to test the latest Android firmware on your own Captivate I897. Also, the performances of your smartphone will be improved as the new software will smoothly run on your device. CM10.2 comes without bugs, issues or problems as the firmware is extremely stable.

As already stated, with CM10.2, the Captivate will run faster, will provide a better Android experience, improved web browsing capabilities, new looks, themes, apps, settings and more power. You will have access to the internal system and you will be able to change almost everything from the default settings. Your phone will become your new playground.

But for being able to do so you will first have to root your AT&T Samsung Captivate. Gaining root access is not an option for you as CM10.2 can be installed only on unchained systems. As you might know, root access means access to the internal system because the factory and default restrictions will be removed. That’s why when rooting the warranty gets void; in fact when gaining root access the binary flash counter of your device gets increased. Therefore, for restoring the warranty, for revoking the root access and for reinstalling the stock restrictions you will have to reset the flash counter – you can do that only by downgrading your Captivate to stock Android OS.

Then, after gaining root access you will have to do another thing: installing a custom recovery image. The stock recovery which is pre installed on all the Android based handsets can’t be used when trying to apply custom ROMs like the Android 4.3 based CM10.2. So, in order to safely complete the guidelines from below you will have to install CWM recovery or any other custom recovery on your AT&T Samsung Captivate. Do note that CWM recovery can be flashed only on rooted systems.

You have everything you need for succeeding with this operation. But, as a recommendation (it is optional you decide whether to apply it or not) you should save the data which is there on the internal storage memory of your phone. Why? Basically because a wipe will be required and when wiping the system all of your data will be erased; and I am talking about contacts, text messages, call logs, internet settings, EFS, current ROM, market apps and everything else that’s important to you.

On the other hand we do have the general pre requisites that must be applied each time you are about to complete an unofficial operation. First, start with your phone; you need to charge its battery and then you need to enable USB debugging option (by going to “settings -> applications -> development”). The charger must be plugged in only if the battery level is lower than 60% because else your Captivate might get turned off in the middle of the installation procedure. Also the USB debugging option must be checked because you need to connect your handset with the computer.

Then, you will have to make sure that you can use a computer, your smartphone and its USB cord. On both computer and phone you will have to uninstall or temporarily deactivate the antivirus, antimalware and Firewall protection because these programs might interfere with the update operation. Finally, it should be clear for you that this tutorial is compatible only with the AT&T variant of the Samsung Captivate which has the model number of I897. So, install CM10.2 Android 4.3 custom ROM only on the mentioned Android based device.

How to Update AT&T Samsung Captivate I897 to Android 4.3 with CM10.2 custom ROM firmware

  1. First of all you have to download CM10.2 Android 4.3 JB on your computer. Do that by going to this page.
  2. Then, you have to get Google apps package (from here) as the same is not included on the update file.
  3. Place the files on the computer and don’t unzip the same.
  4. Connect your Captivate with the computer via USB cable.
  5. Copy-paste or just drag and drop the CM10.2 file and the Google Apps package from computer to your phone’s SD card.
  6. Good, now unplug the USB cord.
  7. Turn off your smartphone – wait a few second before applying the next step.
  8. Reboot in recovery mode.
  9. The first thing to do from recovery is to select the following: “wipe data factory reset” and “wipe cache partition”.
  10. Then return to main menu or CWM recovery.
  11. Select “advance” and choose “wipe dalvick cache”.
  12. Once more return to recovery.
  13. Now select “install zip from SD card” followed by “choose zip from SD card”.
  14. Pick the Android 4.3 based CM10.2 update file and flash the same on your Samsung Captivate.
  15. Return and repeat the procedure for picking up the Google Apps package.
  16. Wait while the process is running and don’t change anything else.
  17. In the end, return to recovery and select “reboot system now”.

The first boot will take longer than you are used to. Anyway, don’t panic because that’s normal. Instead, if your phone gets stuck in a boot loop, you will have to return to recovery and repeat the wipe by selecting “wipe data factory reset” and “wipe cache partition”. Of course, in the end select “reboot system now”.

That’s it; you are done. Now your AT&T Samsung Captivate I897 is running on a custom version of Android 4.3 Jelly Bean firmware.
