Install Jelly Bean 4.3 CyanogenMod 10.2 Nightly Build on Galaxy S2 GT-I9100

For the guide today we will use Galaxy S2 GT-I9100 to illustrate the following idea: how to update the phone to Android 4.3 Jelly Bean using the CyanogenMod 10.2 Nightly Build. The firmware we found best for this model was made by CyanogenMod developers.

So, even if Samsung themselves have yet to offer official Android 4.3 Jelly Bean firmware to be flashed on the S2 I9100, the team that created today’s tool has been kind enough to develop one instead. So that it can be used by consumers who can’t wait to test out their new and vastly enhanced handset.

With this guide you will get to know and use the steps that will upgrade your smartphone. Which means that the tutorial will help you achieve new heights from the Galaxy S2 I9100.

Some of them include customization features and options, stability, better performance as well as an improved battery unit, new applications, excellent speed when it comes to performing various tasks and other enhancements. From what we were able to see, there were no bugs or other problems to be dealt with this Android 4.3 Jelly Bean firmware.

Requirements

To avoid issues arising in the guide later on, you must consider these crucial requirements:

  • root the Galaxy S2 GT-I9100;
  • look for a custom recovery to install on your smartphone (there are two options: CWM Recovery and TWRP; either one is great, but the more popular one of the two is the CWM Recovery one);
  • turn on USB Debugging by opening Settings, then choosing Applications, tapping Development and after that opting for the USB Debugging box;
  • create a backup so that your data does not get lost after the update has been achieved;
  • download Google Apps and then the Jelly Bean 4.3 CM10.2 on your laptop;
  • charge the battery of your handset;
  • flash USB drivers for the Galaxy S2 I9100 on your notebook.

After you have followed these pre-requisites, you should follow some other much-needed things. Like the steps below. If you do that, the update will go on without hiccups; if you miss one of these steps, your smartphone will not feature the upgrade firmware on it at the end of the day. So take things very seriously if you want to get a good result.Galaxy-S2-I9100

How to flash CM10.2 on Galaxy S2

  1. For step number one, the tasks you must complete look like this: after both (file name: cm-10.2-20130814-NIGHTLY-i9100.zip) and the (file name: gapps-jb43-20130726-signed.zip) are on your PC, you should plug these two devices you’re using to one another (tip: the USB cord is the tool that helps with the connection).
  2. Then do as follows: move the downloaded packages from the comp to the phone’s SD card root and, after the transfer has been realized, you can unplug the handset from the laptop.
  3. Now launch ROM Manager app on the smartphone. This is a task whose role is the following: it helps the handset reach Recovery Mode. But what if the Recovery Mode is not reached? The answer to that goes like this: power the phone off, then press Volume Up and Power at the same time; or you can always flash a custom recovery image from the ROM Manager instead.
  4. Now that the Galaxy S2 GT-I9100 is in Recovery Mode, you have to do this task: choose Install zip from SD card. Next move to do: opt for the CyanogenMod 10.2 archive to flash it on the phone; tap “START” to make sure the flashing starts at once.
  5. Then choose the Google Apps and repeat the process you performed when you flashed the other package. In both cases, the flashing process should end after about 4 minutes of waiting.
  6. After the installation has come to a successful end, you have to reboot the Galaxy S2 I9100; for this action, look for “reboot system now” and then choose it. The handset is going to enter the restarting phase in a matter of mere seconds. At the end of this, the smartphone shall quickly boot into the new CyanogenMod 10.2 Nightly Build firmware. And so, your Galaxy S2 I9100 will receive the upgrade it’s been missing for all this time.

NOTE: The smartphone has the update tool in its About Phone setting (which you can open if you tap Settings). The presence of the Jelly Bean 4.3 operating system there indicates the fact that you can do a whole lot of new things with your handset. Just like we said you would.

To see what we meant, go back to the beginning of our guide. And, once you’ve read that paragraph, you should launch your browser and look for all sorts of custom ROMs and the like to improve the performance of your handset; and to make it react and look like you’ve always wanted it to but couldn’t!

The phone can get in a boot loop. Fix this problem by doing the following: power the handset off, take its battery out and put it back. Then repeat the guide.
