hello, thanks in advance, my problem is that my btt gtr does not receive the firmware, when connecting it for the first time (I just received it), pronterface stayed "connecting..." (if the VCP controller appeared in the list of devices), try to update the firmware but the green led never blinked (tried with 3 SD), then I tried swd, with a stlink2, but the VCP controller no longer appeared in the list, and still does not receive the firmware
