Philipych is correct however it depends on what lengths to which you're prepared to go in future to use this device. It's shown that reading from card to dump regions is possible maybe we can at least update firmware with txt commands and you can download maps to a media card and use them from the card too. It's messy and tedious but it can be done. It you want to try updating the fw let me know and i'll make a kit to flash. If it won't even allow the fw regions to be written to then it really is pointless... plus the device will likely die at some point anyway, refusing to even turn on or boot.

Replacing the chip requires it to then be properly reprogrammed. Not for anyone, only for one with advanced skills and the correct equipment.
