Firmware update issue

I recently tried to update my board (v3.5 24v) to the new firmware (v4.7 from 4.6). I tried to use the dfu tool and got an error. After this the board would not show up in the Zadig utility in run mode. I power cycled and switched to DFU mode on the board. It then showed up in zadig as STM32 BOOTLOADER. I then went into the anaconda prompt and this is what went down…

I then ran it again and got ValueError: The device has no langid

at this point I am very lost…

I got very same error when trying to update to “input-filter” fork of latest firmware. I’m running OSX.

I’m quite lost too…

Unfortunately this is a known issue that we haven’t fixed yet. In the mean-time please try using DfUse or dfu-util as described here.
