Vendor extras

Sony's Developer World pages are aimed at developers who unlock and flash Xperia devices. Nothing in the recovery workflow requires unlocking a bootloader, and unlocking wipes user data, so do not do it for recovery.

Windows USB driver

Sony publishes Xperia drivers for developers: https://developer.sony.com/develop/drivers/ (a per-model download list, for example the Xperia 5 V driver entry).

Link rot note: Google's OEM driver table still lists https://developer.sonymobile.com/downloads/drivers/, and that host no longer resolves (DNS failure, checked 2026-10-12). Use the developer.sony.com page above.
