This repo allows you to extract, modify, and rebuild an 83_IMAGE to flash to the HK Invoke.
A lot of knowledge came from: HKHacking, so thank you to coggy9, Ryan, and others who have contributed to the research on how the Invoke works!
The marvell_flash_tool comes from the Harman.Kardon.INVOKE.Flashing.zip tool provided by Harman-Kardon support to flash the last OTA update
