m Intgr moved page Sony Xperia acro S (semc-hikari) to Sony Xperia acro S (sony-hikari) over redirect: The device is more commonly known as "Sony" instead of "SEMC". There's no mention on Ericsson on the device, only the logo remains on the back.

Warning 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.
This device is marked as not booting.
Status: Uses unusual ELF-format boot.img that is not supported by pmOS

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: (see dmesg)

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: (see dmesg)

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.
