How to unlock the device

Enter Developer options on Android and enable OEM Unlock

Unlock your bootloader by following instructions here: https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/

How to enter flash mode

While USB is plugged in, hold Power + Volume Up until the LED becomes blue.

Installation

WARNING: DO NOT NEVER EVER EVER TRY TO ENABLE UFS ON NON-VENDOR/NON-SODP KERNELS! IT WILL ERASE THE CHIP CLEAN (INCLUDING THE BOOTLOADER!) CONSIDER YOURSELF WARNED

Because UFS doesn't work, you'll want to flash the rootfs to an sdcard. Use pmbootstrap install --sdcard=/dev/path-to-sdcard-device. Take a look at partitioning to understand what's going on here.

You'll need to flash some empty bytes to the dtbo due to a bootloader bug. Create a file with two empty bytes with truncate -s 2 emptystuff.img and then flash it with fastboot flash dtbo emptystuff.img

Then flash the kernel as usual, by putting the device into flash mode (fastboot) and then running pmbootstrap flasher flash-kernel.
