[One (M7) Android Development] DeathAngel66669:
For those of you worried that these will brick your phone, I have tested this on my own personal phone and the files were hex edited by me. The screenshots below are from my phone's bootloader screen, and before+after hex editing. Thank you herwegan for providing the hboot hex editing tutorial. All the darkboot firmwares now include the latest Google bootloader. See the last attachment.
