Touch Screen stopped working after Firmware update

Recently i updated my Android device, from KIT KAT (4.4) to LOLLIPOP(5.0). All features where really good  i liked it, but the irony is that, the new firmware totally betrayed me from  using touch wizard. The touch screen totaly stopped working, I tried all the options and solutions given in various discussion forums like 

1. Restart as many times as possible
2. Reboot your system  three times 
3. Hard Factory Reset
4. Remove the battery and replace it after some time
5. Due to dust accumulation it may not work so remove the scratch card
6. The connection of the touch screen with the motherboard may be  loose so tap the screen at the corners 

I tried all these things but nothing happened, it was still in same condition. But the fortunately  except touch screen everything else worked fine, so i connected mouse or keyboard to the device to perform all tasks

Then i started thinking how the problem might have occurred, when i  bought it as a new device it had jelly bean in it, then i updated with the new versions when ever firmware is available for  my device. But this problem never occurred, only lollipop had made this problem, so i thought there should be some problem in software side that is firmware, so for this only two options either i have to DOWNGRADE the system firmware or UPGRADE it, so that there could be bug free version in either of these

I choose to upgrade it further, i checked for any updates fortunately there was an update for the firmware, i went on with my decision. I was right this time, with the new upgrade the problem is fixed. 

The touch screen wizard started working successfully. 

Thus, the chances of bugs in firmware could be common issue, so do not panic go ahead with the best bug-free updates.
