Sony firmware(issue?)

[dymex0]

Hey. Can it be modified to extract Sony action cam firmware? I tried extract HDR AZ1 firmware (.dat), but it gives me error

>fwtool.exe FirmwareData_Update_HDRAZ1V101.dat fwtool2
=== Extract encrypted FDAT record to 'fwtool2/FDAT_enc.bin' ===
Write chunk FDAT to 'fwtool2/FDAT_enc.bin' ... Done
=== Decrypt FDAT record to 'fwtool2/FDAT_dec.bin' ===
Reading FDAT input file: 'fwtool2/FDAT_enc.bin' ... cipher method = 2, block length = 1024
Writing FDAT output to 'fwtool2/FDAT_dec.bin' ... decrypt_fdat_image(blocknum=0): block checksum mismatch (expected: 948d, calculated: f847)!
fdat_decrypt_file() returned error!

This is the wrong place for your question. You're talking about nex-hack's fwtool.exe. This repository contains a rewrite in python (a completely different program). Ask your question at the personal-view forum.

Note that for 3rd generation firmware, you have to recompile fwtool.exe with my patch.
