It installed a generic Android driver and in the list of devices it does not say 'SONY' But Android under 'Universal Serial Bus Controllers'. NB! It did not install the Sony driver as specified by Jolla.

Zadig installed the driver and then it worked. I chose WinUSB.sys in the automatic driver list. Zadig recognizes that the connection to the phone is broken. I installed Zadig and started it up with the phone connected in fastboot mode (fastboot mode is reached on an Xperia XA2 Ultra if you turn it on while gently pressing volume down as it is connected with USB to the computer - this information is in the installation 'manual' that you read when installing Sailfish X). I cannot be sure that it will work for you, but I did this: I was able to use Zadig to install a USB-driver that made it possible for me to subsequently install Sailfish X on my XA2 Ultra. If you don't follow this step, you will have to repeat the install.Disclaimer: I do not take any responsibility if you follow what I write below. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. After typing fastboot reboot, hold the key combo and boot to TWRP. To prevent this, use Google to find the proper key combo to enter recovery.

Note many devices will replace your custom recovery automatically during first boot. From your computer, open a command prompt and type:ĭownload the correct image file and copy the file into the same folder as your adb and fastboot binaries. Press back and go into Developer Options and enable USB debugging. Download the latest ADB and Fastboot SDK Platform-Tools and extract the zip file to your desktop. On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. To set up universal ADB and Fastboot on your Windows PC, just follow the easy steps described below. You can try the Naked ADB drivers or the Universal ADB drivers if you don't already have a working driver installed Windows users will need proper drivers installed on their computer. From the SDK Manager, download only the platform-tools to get adb and fastboot binaries. Find the Android command line tools section on the page linked and install the SDK tools package. You will need the platform-tools from the Android SDK on your computer.
