If you need to tweak, troubleshoot or perform optimization and customization operations on your Samsung Galaxy S2 Plus, then you have to consider in installing a custom recovery image, in our case the CWM recovery tool, on your device. By using the CWM recovery image you will then be able to root your smartphone, a suitable step by step guide being also available here, on Android.gs. But until rooting the system you first have to complete the present tutorial and learn how to flash CWM recovery on your Galaxy S2 Plus I9105.
CWM recovery is a custom recovery image designed for the Android platform, the tool being extremely popular among worldwide Android users as it is compatible with almost all the smartphones and tablets available on the market. Actually, when you buy a new device it is featuring a stock recovery that can be anytime used for performing usual and casual operations. But in order to spice things up and for taking your handset to a new level you need to replace the stock recovery with a custom one. Well, by performing this guide you will be able to do so.
By using CWM recovery on your Samsung Galaxy S2 Plus, you will be able to gain root access, perform maintenance, customization and optimization procedures, install .zip files and a lot more. Also, wiping the system and making Nandroid backups will be possible so as you can see flashing CWM recovery on your S2 Plus isn’t an option for you, especially if you are looking forward in powering up the performances of your handset. I am saying that because updating your Galaxy S2 Plus with a custom ROM firmware is being possible only if you have previously applied a custom recovery image (CWM recovery in our case).
For completing the present step by step guide we will use Odin, so you don’t have to root your device first; as you might know usually, when trying to install CWM recovery root access must be granted. Actually, now we will first flash the recovery image on your Galaxy S2 Plus and only after that we will root your phone.
Anyway, what you do have to perform before starting the installation procedure is a backup. There are few chances to lose your data while using Odin, but if something bad happens, in the end in order to fix things out, you will have to wipe the system of your S2 Plus. Therefore, in order to avoid the unpleasant situations that might occur, I recommend you to save your contacts, market apps, the EFS folder, and everything else you need to.
Of course as you will have to run Odin and flash CWM recovery on your Galaxy S2 Plus by using the same, you will need to have access to a Windows running computer, to your smartphone and to its USB cable. Then, enable the USB debugging option on your device, charge its battery if there is less than 60% power left and deactivate all the security tools that are running on your computer and phone. Without taking care of the mentioned aspects you will have problems in flashing the recovery image and also you will risk in bricking your S2 Plus (in case the phone will get turned off in the middle of the installation procedure).
This step by step guide is compatible only with the Samsung Galaxy S2 Plus model number GT-I9105. The S2 Plus is an improved version of the original Galaxy S2, which means that we are not dealing with the same handset. Therefore, make sure that the steps from below are being completed only for the S2 Plus and not for a similar device because else you can end up in bricking your beloved Android based phone.
