Hi,
I had issues to flash with my FTDI cable as well, because it wouldn't provide enough power to the module.
What I did to have it running flawlessly was to power it via EXT_VCC & GND with 3v3 from an arduino uno board AND connecting all pins from FDTI to UART. Then BOOT0 & RESET put the STM32 into "ready to be fed" mode.
As Seth said, I hope you didn't burn anything by applying 5V to EXT pins...
