I have tried to install via Suite and within the phone. But the installation task ended after the 'Uncompatible' warning message. The phone will even become very slow if connecting to USB cable.

Try resetting ur phone using *#7370#. (THIS WILL REMOVE ALL UR DATA ON THE PHONE MEMORY, so take a backup first)
I have reset my phone after upgrade from V11 to V21 but face this problem afterwards. Do I still need to reset again?
It worths a try.
