I've tried uninstalling and reinstalling Flashtool as well as the drivers.
The fastboot mode works fine. Flashmode worked too its only this time it aint working.
Any idea what's wrong?
P.S I read threads where people had exactly the same issue but unfortunately none of them led to a solution. Any help is much appreciated.
After installing flashtool re-install the drivers from flashtool drivers folder windows will give you plenty of warning but go past all that ,install it and reboot your desktop and handset too...
