There are many hackers who produce modified versions of the original firmware. In general they distribute the original firmware patched in several places, mainly to customize framerates, exposure parameters, etc. | There are many hackers who produce modified versions of the original firmware.

Generally there is **no access to the source code**, so **patching the firmware binary** is a rather delicate task, requiring to know the exact offset of the data into that **specific version of the firmware**, the structure and the lenght of the data and eventually how to **update the embedded checksums**. SJCAM does not facilitate the task, because it distribute different versions of the firmares marked with the same version number. | Generally there is **no access to the source code**, so **patching the firmware binary** is a rather delicate task, requiring to know the exact offset of the data into that **specific version of the firmware**, the structure and the lenght of the data and eventually how to **update the embedded checksums**.
