620 touchscreen unresponsive after recent nokia update?

having the same problem as you suffer in your windows phone . how can we fix it DAAAAN please help us . can you specify it for us . thanks .
 
Phone successfully flashing now =) Will post results of it afterwards.

Thanks DAAAAN :D

Edit:
Yep, working perfectly now. Definitely not a hardware problem. Thanks everyone


how do you do it ? i did what DAAAAN posted but it was not able to work . :(
 
There is any word about what's gonna happen with OEM touchscreens when Lumia Black update arrives? Will it solve this problem with OEM touchscreens?
 
same problem here, broked my phone screen a little, few months ago, from then touch doesn't work like before...also after running phone updates over wifi automatically (though i haven't got any updates notification) it reboot and the entire screen is locked (not accessible) any suggesstions today???
 
Just a quick question. If you update the OS (say using the developer preview app) but not the firmware from Nokia, will the touchscreen work?
 
Updated the official update given by you on my broken lumia but still unresponsive.. please help.. Do we have windows 8.1 update?
