The ones that come with Xperia Companion, or, if you install Flashtool (http://www.flashtool.net/downloads.php), the ones you can find in the Flashtool\drivers folder. Launch the EXE that's in there, select the first 2 drivers, and make sure driver signing is not enforced if you're using Windows 10.
Strange, also using Windows 10 v2004, and my drivers still work... Using the ones bundled with Flashtool, as explained just above!
i've install the Flashtool/driver/driver.exe with disabled signing enforcement and successfully installed, but it does not triggered by my H4113 phone.
