Thank you, cerial killer
Thing is, I've followed the instructions, in that I've copied the **.bin file to a folder marked 'firmware' in the root folder, and restarted with the power cable plugged in, but it still won't boot or update. I think the problem is that I formatted the entire drive (in FAT32), which may have wiped some essential services from the drive, which aren't included in the firmware 'updates' found online. Anychance of anyone having a clone of the original root files...?
Best
