Reverse Engineering SCT Flash Products

#Open SCT Flash Reverse engineering SCT Flash products mainly the X4.

Done

• [Pull file system off device.](sdcard/NO NAME)
• Document important integrated circuits and JTAG connectors.

To Do / Goals

• Figure out what the pin hole button does on the button.
• This prevents the device from being able to communicate over USB. Theorized to be a service mode for repair services at SCT.
• Fully reverse engineer update server API and document.
• Flash custom firmware to the X4 handheld.
• SCT Updater software will flash anything it is given from a HTTP server it contacts assuming the response is correct.
• Removing all pairing restrictions.
• Initial discovery shows this can be done with JTAG and some soldering. However, the preferable way would be through a custom firmware update since there would be no evidence of tampering by way of a broken "WARRANTY VOID" sticker.
• Load unlimited custom tunes(strategies) onto the device.
• This already seems possible software wise. It just looks it is functionality limited possibly due to hardware limitations.
