What is salting a Nook?

TornNook3.jpg

Salting refers to a destructive teardown of a device. It involves unsoldering every chip, removing every shield and then using a tone device to trace the connections in the board from one point to another. Once this has been done, the device is as dead as a slug you poured salt on.

The Photos of the process and comments about results can be followed at the Novaports Gallery.

Why?

The Nook Color has a radio chip which can do Bluetooth, Wifi and FM Radio, but only the wifi was enabled by B&N. It is possible that the Bluetooth radio may, or may not have power. The only way to tell for sure is to open the Nook up, and see if the power pin for the BT radio has +5v. There is no other way. Same thing for FM. Similarly, there are questions about the power connector, the microphone, usb, etc etc. We need this.

How?

After basic disassembly, the board will be heated in an oven to melt all the solder connections on the board.

All chips and other circuit elements will be removed and identified.

High resolution photos will be taken.

Then, the board will be x-rayed using a high resolution X-ray source and a Kodak RVG6100 high resolution dental x-ray imaging system.

Finally, a tone generator will be used to verify traces and connections from one place to another on the board.
