How to enter download/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.
There is also a way to enter Odin download mode without the 3 button combo (link). Instead of the resistor in this schematic being 150k or 619k, make it around 300k (which you could easily do with two 150k or 619k resistors). Will be useful if accidentally soft bricking device.
Installation
- Enter Flash Mode
- Flash pmOS using pmbootstrap flasher flash_rootfs
- Flash kernel using pmbootstrap flasher flash_kernel
