Do not update past 9.60. If a new exploit is found, it will target lower firmwares first.

You must solder wires to the NOR and Syscon chips to read (dump) their data to a computer.

Reverting the Syscon chip and matching the NOR flash data cannot be done via a USB flash drive or a simple software menu. It requires hardware modification, micro-soldering, and specialized chips. Required Hardware

A fine-tip soldering iron, soldering wire, flux, and wires.
