STEP 3

The red line is covering the A17 trace. In order to trick the chip
into thinking the flash is erased in the correct section, you will
need to pull this high. Scrape away at the trace with something
like a multimeter probe. Then solder a very thin wire to it. Be
very careful. Only scrape away at that solder mask above that
one trace. YOU DO NOT WANT TO BREAK THE TRACE. This is the
hardest step in the whole process; the rest is cake. Also solder
a wire to the 1.8v line. Connect to wire coming from the trace
and the wire coming from the 1.8v to your unlock switch. Be
careful, you only get one chance to do this right.
