How to enter flash mode

Before you can flash PostmarketOS, you'll need to unlock your bootloader as described on Sony's open devices portal. This may potentially void your warranty, be warned, and read the warnings that Sony provide also.

Once you've finished these steps, your device will have been wiped. Set up android if you want, you won't have any reason to get rid of it because UFS doesn't work at the moment (see below). Then, either:

  • Power off the device. Holding up on the volume rocker, plug the device into a computer.
  • (or, on android) get an adb shell and run adb reboot bootloader.

Status

This device belongs to the Sony Sagami platform, which is the Xperia 1 III (this one, pdx215) and Xperia 5 III (pdx214).

Work has been done on the device trees in the mainline kernel by the folks over at somainline.

For now installing on the phone memory and sdcard both fail booting, but usb ssh works at least with the sdcard install.

UFS

The phone's internal storage is UFS. Sony's past devices have had a bug that will erase the phone's entire internal storage if you try to start up UFS on mainline, because one of the UFS commands is misimplemented. This includes wiping the bootloader, bricking the device FOR EVER.

We currently have UFS disabled in the device tree, which renders the device's internal storage unusable but means there is no chance of anything getting bricked. It should be possible to patch out this command and reenable UFS in dts on a device-specific kernel eventually.
