Modify firmware GPS Tracker TK103B model and Flash/Update Device

I have a GPS tracer device TK103B for tracking vehicle and with different features.

The device is controllable via SMS commands and uses AT Command set.

I would like to rewrite the firmware to add new commands to device for more information.

For instance user send custom command to device via SMS.

1. GCP*00029* (Get Current Position) - *00029* is the password to authorize response

2. Device will process GCP command by executing corresponding AT command to get position

3. Device sends response to sender phone number with current GPS position.

The project consist essentially of adding commands. Not more than 5 Total.

Will need source code and instructions on how to flash the device.
