This repository contains a set of tools that can be used to flash some manufacturing information, recovery firmware, etc. to Core Devices watches.

It is recommended to use a Python virtual environment to install dependencies, which can be installed by running:

pip install -r requirements.txt

Device needs to be running the PRF (recovery) firmware.

This tool is used to flash unique information to each device such as serial numbers.

A device can be flashed by running:

python mfginfo-tool.py -p path/to/serial/port -s $SERIAL -v $HWVER

where $SERIAL is a 12-character serial number and $HWVER is the hardware version, e.g. asterix.

NOTE: You can also pass --no-lock if you want to skip locking OTP. It can be useful while testing, so you can retry as many times as you want.

Example of a successful run:

Erasing OTP                             OK
Writing S/N             S101220A0009    OK
Writing HWVER           asterix         OK
Writing PCBA S/N        S101220A0009    OK
Locking OTP                             OK

This tool is used to flash the PRF (recovery) firmware into the external flash.

PRF can be flashed by running:

python mfgrecovery-flash.py -t path/to/serial/port -p firmware path/to/prf.bin

Example of a successful run:

Erasing... done.
...............RRR................R.R.R..............RR.R..............R...R..............R.RR................RR..R.............R...R..............R.RR................RR................RR...............R..R................RR...............RRR................RR.......R..........R......R..........R.......R.........R....R.R.
Success!

This tool allows to access the PULSE console available on the serial port.

It can be used like this:

python pulse_console.py --tty path/to/serial/port

If using a firmware with log hashing, you can provide a dictionary file:

python pulse_console.py --tty path/to/serial/port --log-dict path/to/loghash_dict.json
