Make sure you reset it with BOOT0 pulled high in order to enter bootloader mode. You don't say how you "invoked the bootloader".

yes that is exactly what i did to enter the bootloader mode. The application code in flash stopped after reset with BOOT0 pin high. But the STM32 flasher couldn't communicate with it .
