Hello,
Could you please provide instructions to rebuild the  /data partition (in case accidentally deleted).
That also erases the SKU number, which has the specifics of the on board hardware.  There are several options for Modem and Transmitter, and I dont know which ones are on my drone.
I'm reinstalling the VOXL SDK, but  voxl-configure-mpa fails since the SKU number is incorrect.
Please advise on how to proceed.  Thanks.

@Moderator , thanks for the prompt response.  I've followed those instructions. The problem is that there are some specific choices that are not clear based on the hardware or software that was used for my drone during production.  For instance, Transmitter options. I know that I have ELRS 915 MHz transmitter, but that corresponds to three transmitter options (7, 8, 10) and similarly for the modem: I have no way to know if my modem is M0193 or M0184.
I have tried different combinations of these options to create a SKU number. In each case I run  voxl-configure-mpa  with the new SKU number and the process fails (hangs app showing; communication ERROR:)
It Seems the problem is from not having the correct SKU number, but it may be that other file(s) are needed to complete successful  voxl-configure-mpa ?  Please let me know your suggestions.
Thanks.
