I wonder if Bionic Droid cannot have a boot manager with a key. From what I can say, boot loader closed in Droid X, Droid 2, Droid pro, etc. is a tie in the hardware directly to the function of eFUSE Texas Instruments OMAP processors. The Motorola droid bionic is dissimilar from the above, however, which is powered by an NVIDIA Tegra 2. I have to be inquisitive if the Tegra has analogous operations to lock the boot loader, or Motorola can have to do incredible extra like HTC and obstruct memory, which is an easier way of being hacked.
