To install this firmware:
In Scream!’s main window, right-click on the unit’s icon and select Terminal from the pop-up menu:
Check that there is two-way communication with the unit by pressing Enter. It should reply with ok on a new line.
Type re-boot to reinitialize the unit, and confirm with y. As it is restarting, the unit will report its status over the terminal connection. After a short while, it will pause. If you do not enter a command in the next 13 seconds, it will continue booting up normally.

To update the firmware, type h8upload during the pause and press Enter. If the unit replies 8upload undefined (or similar), it has failed to receive one of your keypresses. Type h8upload and press Enter again.
You should see a message like
Erasing page 15 ....done Ready to upload H8 code...
Once the message Ready to upload has appeared, right click anywhere in the terminal window and select Send file from the pop-up menu:
Navigate through the directories on your computer and select the file to be uploaded, or type in its full path and file name. Click Open.
Whilst the file is loading, a progress window will be displayed. Depending on the speed of the link, it may take up to 20 minutes to transfer the firmware.
Once the file is fully transferred, the old installation will be backed up and the new one put in place. This will take a couple of minutes. When you see the READY ok> prompt, wait for about 30 seconds, then hit Enter a few times to verify that the unit is awaiting your input. Finally, type re-boot to restart the unit with the new firmware, and close the terminal window to resume data transmission.
