Its true that a lack of standardization on phones makes things a bit harder but its as you said, still the key point is that they need to make the firmwares opened up. If manufacturers want to keep it all locked down then they deserve and should expect these type of attacks all the time. If they don't want these to happen, they should make their firmwares available and upstreamed or at least not cause roadblocks toward reverse engineering of the device by means of cryptographic locks or otherwise.
