Looks like the locked bootloader of the HTC Sensation was only the beginning of a trend that will continue with the company’s other major handset launches. It was discovered that the HTC Evo 3D will also feature an uncrackable bootloader along with secure kernel images and locked recovery mode. The signed bootloader ensures that the EVO 3D only boots with approved software builds, making the implementation of custom ROMs all the more difficult. Instead of attempting to crack the bootloader (a task that is nearly impossible due to 256 bit encryption, the best bet to gaining access to development on the handset is via a workaround that could include locating a leaked development ROM or finding a way to trick the EVO 3D’s bootloader. We’ll leave that up to the more than capable development and rooting community. They’ve faced hurdles before, but rarely have they failed at cracking whatever handset they choose.
