Dumping firmware from JieLi chips

JieLi chips are fairly common in Bluetooth audio devices, but they are also becoming more common in miscellaneous devices. Fortunately, retrieving the firmware is mostly straightforward.

We heard you needed some more time, so we wanted to let you cook.

We decided to push the Phrack 72 CFP deadline back until June 15th.

Stay tuned for upcoming Phrack events.

Print this flyer out and give it to someone IRL!!
