Thanks to whoever sent me the LTC, it's much appreciated 
gvsrusa I would suggest downloading and writing the firmware to a microSD card as per the innosilicon manual.
Then boot it up using the microSD card in the slot and leave it a couple of hours to flash (not sure exactly how long it takes but the img was several GB).
Then if you can ping it on 192.168.1.254, pop out the card, and reboot the A5.
Assuming you can now access the web interface, download the other firmware (smaller one) and flash that .bin file via the web admin interface.
If that works then after the reboot, re-configure your network and re-enter your mining pool details.
Good luck! I've had no replies at all from Inno via their web support form yet ...
