Unfortunately that doesn't seem to be how the computer industry works. Think of all the game, software, hardware companies that don't exist any more. How many of them have released their source code, hardware specifications or given any help for previous customers. Generally the companies got "more important" things to worry about if they're going bankrupt. Sorry to answer your question, yes it's actually quite easy to flash the firmware. You don't actually need any hardware for it (unless you brick your device somehow). The only issue (as you stated) is it must be signed by Intel to work.
