E fuses require a lot of power to burn in the fuse. So find the pin in the chip with high voltage, and suppress it to prevent e fuses from burning in.

- koala_man 8y agoI would assume that the firmware also verifies that the fuses have been burnt before continuing booting.
- dpiers 8y agoIt does, but this prevents your system from being irreversibly updated by accident. I remember removing R6T3[1] on my Xbox 360 so that it wouldn't accidentally be updated to a non-homebrew/exploitable version. Without the resistor present, the voltage wasn't high enough to burn the eFuses. An update could run, fail to boot, and I could reflash it to the old version. 1: http://www.free60.org/wiki/R6T3 http://www.free60.org/wiki/R6T3
