After installing drivers plug the phone and wait for drivers to install and note the com ports

sol) install VC++ 2005 redistributeble SP1 ATL security upgrade
Prob) receive incorrect parameter error.
sol) you are using Chinese flash tool so make sure your copy of windows supports Chinese change local settings in control panel or use English version
Prob) error in gnqc bp_image file doesn't exist
sol) make sure your stock rom is Indian version and does not have Chinese characters
Prob) open com port failure
sol) check if your com ports are used by any other app if not it means com port drivers are not installed for your phone all you have to do is to reboot the phone while still plugged in and it will install another set of drivers
