I was a htc hd2 user before. And probably you already know, it has 2 super second bootloader's (sbl) which are based on windows ce kernel and can run android kernel and windows phone 7 efi.
At the moment, we (nokia x2 users) have several stock and cm11 based roms, maybe we will have a bug-free cm12 rom too. So i enhanced twrp recovery and created a multibootloader kernel which boots up to 2 unlimited kernel and already has a fully working twrp 188.8.131.52 recovery features.
With this tool, we can use multiple roms (a nand and a sd-ext based roms) simulatansly. We can select which rom to use at start up process.
When you installed it to your phone, it replaces your kernel (boot partition). So when you boot up to device, it will ask to which kernel is executed. When you select a kernel, multibootloader flashes it to recovery partition and immediatly reboot to recovery to execute kernel.
I also added flash img file and dump rom features. Flash img feature is enhanced for flash system, custom and data images directly from bootloader. This is for flashing roms which havent a flashable zip properly. Dump rom feature is a utility to back up your current rom (nand or nativesd) for sharing it other users. It creates system, custom and data partitions images.
