OR replace files in this OTA to make it more suitable to our needs, such as adding supersu. It could especially be helpful if anyone has an MDK update package laying around. Maybe we could modify the MDK software update to make the phone think its installing VRUDMI7?
Just something I was thinking about. Hopefully its useful to the right minds and they figure out a way to get us unlocked again. I had an MDK that had a hardware malfunction and had to replace. My replacement happened to be vraum7

Unfortunately the current bootloader requires a flash of new software that is signed with an encrypted key as a signature.
You can't flash anything that is not signed correctly.
The keys are secret and the only information you have is probably a hash code in the current bootloader that tells if the new one is valid or not.
Unless there is something, a bug, if you will, that will allow the flashing of a unsigned bootloader; forget it.
