The Mariko bootrom is cryptographically locked. The only theoretical exploit is a new CPU cache timing attack, but the volunteer teams (Team Atlas, SciresM) have stated that the heat generated by such an attack would damage the V2’s battery controller.
, while the original V1 came in a box with a gray background. 2. Required Hardware (Modchips)
: This is not a beginner-friendly project. It requires microsoldering to tiny capacitors on the CPU.
