Bold 9900 died after OS 7.1 upgrade


I am new on here - so greeting to all.


I tried to upgrade my 9900 to OS7.1 after reading on this forum that it will enhance the battery life.


I managed to download the upgrade and tried to run it. When it ran - it said it was backing up my contacts etc and then it hung. Now I am trying to switch it on and it wont budge. It has been on charge for 4 hours now - but still nothing.


Any advice would be greatly appreciated as I didnt keep the warranty :-(
