Semi broken Xperia 1 III

[piero]

For your information, this phone have no RECOVERY /partition, recovery software is part of a boot partition.

You need to fastboot flash dtbo, vbmeta and vendor_boot prior to temporary fastboot boot recovery…

Flashing Stock Firmware on Sony Devices

If you are using a Windows PC, and you have not unlocked the boot-loader on your device, you can use Sony’s flash tool EMMA to flash the latest stock firmware on your device. Full documentation and download are available on the Sony Developer World website.

Flash tool | Developer World

If you are using a MacOS or Linux PC, or if you have already unlocked the boot-loader, then you will need to use Flashtool

• Downloads for Windows, Linux and MacOS available at http://www.flashtool.net/downloads.php
• Good instructions for use on xperiafirmware.com

Finding the stock firmware

Before you can flash it, you need to find the correct firmware to flash. The EMMA tool - if it works for you - will find and download the latest official Sony firmware for your device automatically.

Otherwise, if you are using a Windows or Linux PC, you can use the XperiFirm ~ Xperia Firmware Downloader to find and download the latest official Sony firmware for your device. (The program is written in .NET and ships as a Windows .exe file, so Linux users will need to install Mono).

If you need access to an older version of the firmware, if you are running a MacOS PC, or if Xperifirm does not find the firmware for your device, then you will need to find the firmware elsewhere on the internet. Places to look include
