How to flash genuine HM-10 firmware on CC2541 (make genuine HM-10 from CC41)

Hello,

Thanks Hexor for this tutorial and for sending me the firmware!

But sadly i can´t get it to work. I did everything like in your tutorial but when i start flashing the firmware it´s not responding....but when i press ctrl & c and startover again sometimes it´s starting. but only 1 apears than it´s over.
Do you got me an idea what is wrong? The connections on the cc2541 are soldered correctly and i got 2 modules which act the same way.

Thank you!

regards Ed
