Hacking Amazon's Eero 6 (part 2)

In the blog post "Hacking Amazon's eero 6 (part 2)" by Naz Markuta, the author details the process of extracting firmware data from an eMMC flash chip of an Amazon eero 6 device. After attempting non-destructive methods without success, the author had the chip desoldered and proceeded to extract the firmware. Various techniques and tools were used, including a BGA153 adapter purchased from Aliexpress. The author encountered challenges such as failed attempts with different adapters and soldering issues. By identifying the pinout and soldering jumper wires to the eMMC module, the author successfully read the chip in 4-bit transfer mode. The firmware was dumped using the dd utility, resulting in a raw dump copy. The extracted firmware contained 23 logical partitions, which were then extracted and mounted for further analysis. The process involved using commands like 7z to extract files and mounting them individually. The successful extraction and analysis of the firmware demonstrate the author's persistence and technical skills in hacking the eero 6 device.
