This is based on the P89LPC935 controller, your details may differ, check details with your particular processor's user manual.
1. When the application is running in the device, you have to enable the
UART Break Reset bit, this is in the AUXR1 register on the 935.
2. Set the Boot Vector.
Set the boot vector to 0x1F (this is its state from manufacturer so you may not have to do this)
3. In flash magic select "ISP/start bootloader"
4. Ensure the "send break" button is checked
5. Press "start bootloader"
6. From the main screen press "start" to update the code.
Good luck,
ian
