The tutorial should also be used by the S2 Plus owners who have a rooted device. As you probably know that, on a rooted device the OTA updates cannot be received and automatically installed.

This tutorial also works in both S2 Plus device, rooted and non-rooted devices.

For applying the latest update, we will use the ODIN software which is a flashing tool developed by Samsung, which means that to install the firmware the root rights or the CWM recovery image in the S2 Plus device is not required.

Applying the latest official Android 4.2.2 JB XXUBMH4 firmware, you will restore the warranty for the rooted devices and also the root rights will be revoked.

The Samsung Galaxy S2 Plus device will be restored to its default state, and the new official Android 4.2.2 Jelly Bean firmware will be running on it.

Pre-requisites and Guidelines:

  • Back-up all your personal data stored into device’ internal memory, also back-up the store applications and custom settings from the device. This is a manual method, and you can never be too careful when it comes to your personal data and information from your device, so a full back-up is recommended.
  • The ODIN application is compatible only with the Windows operating system, so we will use Windows based PC for installing the new update.
  • Disable or deactivate all the security protection from both device and the PC, programs as Firewall and Antivirus can interfere with the flashing process and to interrupt the same in the middle of the update operation.
  •  The S2 Plus device must be charged enough, so make sure the device’ battery has more than 70 % power left in it.
  • Enable the USB Debugging mode from the following path: “Settings>Applications>Development >USB debugging”
  • Note that the actual guide works only with the Samsung Galaxy S2 Plus model number I9105. Don’t apply this manual guide and the latest Official JB 4.2.2 OS with XXUBMH4 Firmware on different variants otherwise this may damage your device.
