With such good specs and features, it could easily handle the newly launched Android L update.

Steps to Install CWM recovery on Galaxy Core 2:
Download the CWM recovery package file to a specific folder on your computer. Extract it and you’ll see a recovery.tar.md5 file. Also, download and extract the Odin3-v1.85 on your computer. You need to boot your Galaxy Core 2 into downloading mode. For that firstly switch off your phone completely till it vibrates. Then press and hold the Volume down key + Home button (middle button) + Power button simultaneously till you see a warning message. You may leave all the three keys now. Just press the Volume up button to enter the downloading mode.
Using a USB cable connect your phone to your PC. Now launch Odin3-v1.85 software on your PC. As you open it, the ID: COM section in it will turn yellow. Also, an ‘Added‘ message will appear in the message box window. This will confirm that your Galaxy Core 2 has been successfully connected to your PC. If such a thing doesn’t happen then try using different USB ports or different USB cables or just re-install the device-specific drivers from the links given in the Prerequisite section.
Now tick the Auto-Reboot and F.Resest Time options present on the Odin window.
On the Odin window, to the right-hand side, you’ll see a tab named PDA tab. Select that and locate the ‘recovery.tar.md5‘ file which you have downloaded before & select it.
After completing everything as mentioned above, simply press the Start button located on the Odin window to initiate the CWM recovery flashing process. Your phone will automatically reboot itself while going through the process. It is recommended not to touch or remove the USB cable until the process is complete.
Be patient until the installation of CWM recovery completes. It will hardly take a minute. As soon as it completes, you’ll see the Pass message on the Odin window. You can safely remove the phone from your PC now. If due to any reason the process fails or if Odin gets stuck or in case your device gets boot loops, then don’t panic. Just close the Odin window, remove and re-insert the battery from your device. Again go into downloading mode and repeat the whole procedure as given above. For confirming whether CWM recovery has been successfully installed or not, boot your Galaxy Core 2 into recovery mode. For that, firstly switch off your phone completely. Now press and hold Volume up + Home button + Power button simultaneously until the recovery mode appears. You’ll notice that Clockworkmod recovery is properly installed on your Galaxy Core 2. You can restart your phone by selecting the ‘reboot system now’ option present on the recovery mode itself.
