@ -81,15 +81,15 @@ Checksum
A user called "tidy" has found out what the header bytes are meaning and how checksum is compiled:
> bytes 0-3: file magic `UMDA`
> byte 4: Platform *
> byte 5+7: Customer * * (whatever that means its extracted from decompiling the header parse code)
> byte 6: Model *
> byte 8-10: Version number
> byte 11-12: build number (little endian)
> byte 13: flags seem to have impact on the update process but I'm not sure in which function

> The checksum is calculated by interpreting the file as a little endian int16 stream, adding up its
> values, truncating the 16LSBs after every addition and calculating the value that is missing to
> sum up to 0x10000. I.e. if one calculates the checksum as described over the whole file including
