How to enter flash mode

Start powered off. From there, hold the volume down button, home button, and power button. Once the phone buzzes, release the power button.

Installation

  • Unlock the bootloader if it hasn't been unlocked before. (My memory is hazy, but I think I did it a sketchy way. I downloaded KingoRoot and rooted my device. I then installed ClockWorkMod from here although I think TWRP by jt works fine as well. Then get a ROM to overwrite the original. Compiled a recent one here)
  • Enter Flash Mode
  • Flash pmOS using pmbootstrap flasher flash_rootfs
  • Flash kernel using pmbootstrap flasher flash_kernel

Current Known Problems

  • Red Tint
  • Power button boot loops (Seems like this had to do with pmOS itself. It's fine now, but doesn't do anything)
  • Screen on 24/7
  • Only works on Weston
