In an attempt to sharpen my hardware hacking skills, I took on the challenge of extracting firmware off a flip phone π±.
But... I kind of underestimated my opponent:
- No trace of the firmware online
- No OTA updates
- Debug interface nowhere to be found
- The chip holding the firmware has no legs
Quite the challenge.
I ended up dead-bugging the chip and wiring it to the Xgecu T48 Flash programmer.
Enjoy!
