Android 4.3, also known as Jelly Bean, launched in the second half of 2012, hitting almost all of the Nexus devices, the Samsung Galaxy S3 and S4, and most recent HTC phones. For people with some mobile carriers, or those using older (but still very capable) hardware like the Galaxy S2, waiting for Jelly Bean has been a 'sit and hope' affair. Luckily, S2 owners looking for Jelly Bean don’t need to wait any longer. The Android custom developer community has a version of Jelly Bean ready to go on your device, and all you need to do is follow the steps below.
Edit Before Updating to Jelly Bean, Make Sure:
- Your Galaxy S2 has been rooted.

How do I update my Samsung Galaxy S2?
I would like to update my galaxy S2 4.1.2 to 4.2.2, Jelly Bean.
You can update your Samsung Galaxy S2 from 4.1.2 to 4.2.2 by choosing any of the following update procedures:
- Download and install Samsung Kies on your computer. Once the download is complete, connect your Galaxy S2 to your computer via USB cable. Open Kies and wait for it to detect your phone. Once detected, Kies will search for the latest update available and will give you the option to download to the latest update. Download the update and automatic updating should follow.
- You can update through your phone's over-the-air (OTA) update. Download updates by going to Home Screen > Apps icon > Settings > About Phone > Software update > Update. Galaxy S2 will now search for available updates and will ask you if you will proceed with the download.
For a third option for updating your Samsung Galaxy S2 to 4.2.2, please do the following.

What do I need to install after installing 4.3?
Do I need to reinstall all Apps that I have currently downloaded? Also, when there is a new version of android, do I need to manually install that or will it be taken care of automatically in the same way that I check for Android updates right now?
You do not have to reinstall applications when you upgrade your phone's OS version. For future updates, you can opt to manually update through Samsung Kies, or wirelessly through Over-the-Air (OTA) updates. These are very easy and convenient ways, so there is a very small chance that these update options will change in the future.
Understand that this update may not come standard for your device depending on the time that you asked this question but you can find this update in your update phone option.

It seems that you have rooted your phone to another update of this device instead of having the required update for the phone. Uninstall and reinstall Cyanogen mode to see if you can get your Google Play Store to show up to download applications.
The CyanogenMod roms are just the basic Android OS and do not offer the Google apps package. You will need to flash the package zip file using a custom recovery like Clockwork mod or TWRP.
You can find the 10.2 CyanogenMod Google apps package download here:

A download link is not all you are going to need for this process. You will need to follow the steps in the article above, and root your device so that you can get the jelly bean update. The update to Android 4.3 Jelly Bean does not come standard for the S2.
You can, however, install an open source 4.3 update without the Samsung touchwiz UI for your phone. You would not need to use Odin, but instead use the built in recovery of your phone. You can find the download for the S2 device here:
You`ll also need to Google apps package, which includes the Play Store, Gmail, etc, here:
You can flash both zip files from your phone`s recovery mode menu.

I updated my Galaxy S2 to Jelly Bean with odin and it is no longer working.
I Update Jelly Bean Version with odin My Phone Galaxy S2 SHW-M250S is no longer working. How do I solve my problem?
Was the update completely flashed on the phone? If it was, the phone would have rebooted into the new OS. Connect the phone to the computer and run Odin again. Make sure the com port is lit up, which will indicate that the phone is connected correctly, and with the drivers installed.
Check out a screenshot here: http://screencast.com/t/VHycqecGKxXN
You`ll need to put phone in download mode when connected to the computer. To do so, press and hold the “power” and “volume down” buttons at the same time. Load up the jelly bean firmware file and flash again with odin. Make sure this time the file is fully flashed and you see the pass sign:

From the recovery screen, I cannot see "install zip from SD card." Could you tell me where it is?
In the step: "From the recovery screen, choose 'install zip from SD card' and then choose the .zip file that you saved on the root of your SD card." From the recovery screen, I cannot see "install zip from SD card", could tell me where it is?
If you don`t have the "install zip from SD card" option on your system recovery, this just means that you are not using a custom recovery. Please install CWM on your phone first before proceeding with the update. To install CWM on your phone, please do the following.
NOTE: Make sure your phone is rooted before proceeding.
- Download CWM for your Galaxy S2 from here: http://clockworkmod.com/rommanager.
See this image http://screencast.com/t/zXuGbQtiXmi
- Copy the previously downloaded CWM file onto your SD card.
- Copy the Android 4.3 Rom you have downloaded onto your SD card.
- Boot into your stock recovery and select "apply update from external storage".
- Select the CWM file you have copied in the previous step.
- You will now boot into CWM recovery interface (this custom recovery is temporary and will be gone after reboot.)
- You will now have the option to "install zip from SD card".
- You can now start on step 5 of "Steps to Update Galaxy S2 to Jelly Bean 4.3".

Problem with installing Jelly bean and google apps?
After selecting "apply update from sdcard" and then the jellybean 4.3, it says E: failed to verify whole-file signature and E: signature verification failed.
Are you using a custom recovery to install the jelly bean update? If you are, there should be an option to turn off signature verification. Look for the option called Toggle Signature Verification and turn it OFF. Reinstall the update zip and it should go through.

Intermittent signal issue on s2-GTi9100?
Intermittent signal issue. replaced sim card but still have same issue. on jellybean 4.1.2
The Samsung Galaxy S2 has a lot of issues, not only with the device itself, but with the software that is on the device. Contact your mobile carrier so that they can help diagnose the problem remotely to your device.
My phone isn't starting. It stops on the Samsung logo. What can I do to resolve this?
There are several ways for you to try to resolve this issue. Try the suggestions below and see if this solves anything. It may be that your power button has gotten stuck, which would be why you are experiencing this problem during the reboot sequence. Try fiddling with that and see if it is stuck, and if so, whether or not you can unstuck it. If that does not resolve your issue, turn off the phone and take the battery out, then insert it back in. If it is still stuck in the boot loop, your phone likely needs to have a general cleaning. You’ll need to take all the parts apart to clean (in this case, specially the power button), and remove any dirt or grime lurking in your phone. Before taking the phone apart, try to press and hold the power button only for about a minute with extra effort, then after one minute shake the phone. It may sound ridiculous but it can resolve the problem. It’s also possible that a battery issue is keeping your phone stuck in a boot loop or stuck on the Samsung Logo. What you need to do is check to see if the battery works fine. If you own another of the same battery, you can also try swapping it in and checking to see if you have the same issue. If you have the same issue, you need to take your own battery out of the phone and you can use a pick or toothpick or an emery board (Nail File). To fix a potential battery cleanliness issue, look for the three little bronze terminals in the place where you place your battery in your phone and clean them up. Next, gently scrape the three terminals on the battery then insert it back on the battery dock, then turn on the phone and see if the problem persists.

Is the official Samsung JB available for download?
I would like to install the original Samsung OS. I currently have CM 10, which doesn't have the Sim Tool Kit app. I know the Official Samsung OS does.
All you have to do is go into your phone`s settings, tap “About phone” and then tap on the “System update” option. This will download the latest available firmware for your phone from your carrier. Just let it finish download and complete the installation and you should have the original Samsung OS back on your phone.
Note: This will erase your user settings, as well as your Cyanogenmod rom and root access, if you had it previously.

It’s loading for 15 minutes and still loading what am I supposed to do?
If you have installed the ROM on your phone and it just keeps on loading, boot into recovery mode by pressing the “Volume Up,” “Home,” and “Power” buttons. Once you have access to the Android recovery, you just need to select “Reboot” for the phone to reboot and use it once again.
If you have tried that and it did not work, follow the same steps to install the stock ROM and start flashing it again. Make sure also that your phone is properly plugged into the computer so that it will not be interrupted during ROM installation.
