WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) pmaports#599 has been considering dropping it. The processor of the device may support the armv7 architecture. If so, you can modify the device package and change the architecture accordingly. |

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.
Downstream kernels
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 manage to initialize the display backlight and then crash pretty late in the initialization process with error:
BUG: Bad page state in process swapper/0 pfn:5dcba

Mainline kernel
No peripherals supported yet, but `/dev/last_kmsg` can be extracted with a binary kernel (e.g. TWRP). Sadly the boot process appears to hang after executing `/init`: https://paste.ubuntu.com/p/zdJ9TbyJxX/

How to enter flash mode
Power off the device. Hold Volume Up as you plug the USB cable into the device.
Alternatively, perform a hard reset by holding Power and Volume Up buttons. When the device vibrates, release the Power button *first*, and it will boot into fastboot loader.
Installation
Follow Sony's instructions to unlock the bootloader.
