S2 owners are more than likely feeling the urge to switch over to a newer build since their handsets are now beginning to age. If you don’t buy a younger model such as the S3, there is very little left to play with because you already know it all. This update happened over the air for certain areas. If you were not in the regions, then you can update manually by following this guide.
When thinking about what this has in store for you, you have to take a look at what device it is running on because they can vary even if it is the same version number. In this case, it’s something to keep an eye on because the older the machine is it will lose some of the key features when being compared to the latest type of handsets instead. For for the most though, you can expect a very similar experience, especially when it comes to checking out the smoothness of the software. That’s an important factor too, because it was the performance that was the main thing worth noting when we think about steps up from the original Jelly Bean.
Get used to backing things up if you can just to make your life that much easier. Because it’s a Galaxy we are using here, it has a Miro SD card. All of this range has them, even the older ones. Technology will continue to change and in time we can expect the word Micro becoming extinct for something smaller and with a slightly different name. For now, it seems we have at least a few more years of enjoying this one. If you own more than one handset, then it is useful because you can use the same card and insert it into the other devices and use the same saved contents from it. It will include contacts, calendars, applications, settings and anything else you may have changed since you began with the stock experience.
You can buy a Sandisk SD card reader, and this will let you copy all files on the hard drive of your Windows or Mac. Now you can create your own folder and have everything stored in here for safe keeping.
The Galaxy S2 will be plugged into the Windows-based computer when you are using ODIN. There is no reason to have a lot of battery charge left before starting for this reason. You should finish the guide with more battery power than when you started.
If you are only trying to update manually because you don’t think it has arrived OTA for you yet, then head over to Settings > About Phone > Software Update and double-check before you start. Sometimes it can be there, and you didn’t realize. If it is there, simply confirm the automatic installation instead!
The Samsung Galaxy USB drivers need downloading if you don’t already have them.
The USB debugging mode will also need to enable. To do this go to Settings > About Phone > Tap build number 7 times until the develop option appears.
How To Flash XWLSS Android 4.1.2 Jelly Bean On The Samsung Galaxy S2 I9100
1. Download the Android 4.1.2 I9100XWLSS for the Galaxy S2 and extract the file. We recommend the desktop for easy access. Download ODIN 3.07 also.
2. Press the power button to switch it off. Now press it again, along with the other keys to make it enter download mode.
Before we get stuck in the computer, after you boot it up be sure to put the security programs such as anti-virus on hold for now. You can achieve this by temporarily disabling the one you have now. If you are worrisome, by all means, you can do a complete uninstallation, but note that it is not necessary to do such a thing just for this. Whatever you did choose to do, it’s a good idea to not forget what has happened because it will need to be turned back on again as soon as you finish to prevent any nasty elements entering your computer or indeed the handset itself.
3. Now from the Windows PC, open up ODIN, which you downloaded. Your phone should come with a USB cable in the box it came with when you bought it. Get the wire and plug the Galaxy S2 into the PC. You should see a message confirming the device has been recognized by ODIN.
It is the last chance you have to get a good backup in. There are other ways of doing this other than the way that I mentioned above here. Many people have their own preferences about what they prefer to do, so feel free to go ahead and do that instead.
4.From the extracted contents in step 1, look for the code file. Upload a file inside the PDA area.
5. Put the pit file where it says pit. (Only use the pit file if you found it in this extracted file from this guide. If it isn’t there, don’t touch it. Do not use another one in its place.
6. Do not make any other changes that are I haven’t already mentioned here. All of the other settings will be sitting the way they should be and are the default setting’s for the Odin application. To save us from writing an unnecessary list and making people confused we will just use our own knowledge because we already know how the rest of the settings are inside Odin.
7. Once you have thoroughly read through the guide, and you are confident everything is how we want it to be then you can press the start button.
8. Remember to always right-click the USB symbol in the Windows taskbar and click on the green arrow that says ‘safely remove hardware’ when you hover the cursor over it. Now right-click > select the gray area >USB Mass Storage Device > stop button > select the flash drive in the ‘stop a hardware device’ section and click OK. It will now say ‘safe to remove hardware’ in a bubble that’s popped up on the taskbar.
