What works

This device uses a non-standard ELF format boot.img file that is not supported by postmarketOS (yet):

% file boot.img
boot.img: ELF 32-bit LSB executable, ARM, version 1 (ARM), statically linked, corrupted section header size

intgr has a working hacked postmarketOS toolchain for building compatible boot.img files.

What does not work

Booting.

After trying out tens of different combinations of kernel sources from the web, I couldn't find any that get as far as initramfs.

The best sources found crash pretty late in the initialization process with error:

BUG: Bad page state in process swapper/0  pfn:5dcba

How to enter flash mode

Power off the device. Hold Volume Up as you plug the USB cable into the device.

Installation

Follow Sony's instructions to unlock the bootloader.
