I was unable to install the fastboot driver under Windows 10.

First, I tried the driver suggested in Sony's unlocking-instructions but run into a hash value error.

Then, I tried the driver linked to in Jolla's intructions found in the "Xperix X Driver" folder, closly following Jolla's instructions - but no luck.

I also tried to disable driver signature enforcement to thus instal the driver suggested by Sony but that was impossible due to the secure start guidelines

EDIT: GOOD NEWS! Here is the solution that finaly worked for me:

Should you have this problem, this is what helped me eventually:

try to follow Jolla's instructions but if that doesn't work try instead of steps 2.9 to 2.12 of Jolla's instructions:

look where the "S1Boot Fastboot" device shows up in you device manager. For me, it initially showed up in "other devices" with a warning sign because of a missing driver. Some attempts later, I found "S1Boot fastboot" under "USB devices" - I don't know why.

A right click on "S1Boot Fastboot" will open the menu for driver installation. I had no luck following Jolla's instructions or Sony's instructions. I already loaded the "android_winusb.inf" as suggested by Sony and the "sa0114adb.inf" file following the link in Jolla's instructions. I was not able to use the "sa0114adb.inf" file the way suggested by Jolla in steps 2.9 to 2.12.

However, after opening the menu for driver installation for the "S1Boot Fastboot" device, I chose "Let me pick from a list of available drives on my computer" and instead of "have a disk ..." (Datenträger) (which I initially tried without success) I tried the options in the table shown (I am not shure if that table was there at my first attempts). The table had two columns, a first column with two entries and a second column with three entries. From the first column I chose "WinUsb-device" and from the second column of the table I chose "ADB-device". I got a warning but decided to have the driver installed anyway and it worked, driver was installed and I could proceed after hours of trying!

What does "no luck" mean? Did you follow Jolla's instructions point by point? Do you have an error message at some point?

When trying to update the fastboot driver as instructed by Sony or Jolla, I only run into errors - either "drive not fouond" although I went to the right directory were "sa0114adb.inf" is found or the hash value error when using sony's "android_winusb.inf"

I run into the following errors:

  • when following the sony-way and using the "android_winusb.inf" file in the right dirctory ../Appdta/Android/sdk/extras/google/usb-driver I had an hash value error when trying to update the "S1Boot Fastboot" driver

  • when following the Jolla-way I had a "driver not found" error when trying to update the "S1Boot Fastboot" driver although I linked to the directory were the "sa0114adb.inf" file was found

O.k. I might have found an answer myself: somehow I managed to install an ADB driver found in the Windows 10 device manager under "USB-device" (as opposed to "other devices" where the fastboot device showed up automatically and asked for a driver) after clicking "Let me pick from a list of available drives on my computer" and chosing "WinUsb-device" and "ADB-device" instead of steps 2.9 to 2.12 of Jolla's instructions that did not work for me

They did not work for me either - that is why I posted this question. Since five minutes I know have an Xperia X with sailfish - despite the instructions. May I suggest that driver installation under Windows 10 is illustrated in more detail?

I followed the guide step-by-step on Windows 10 Pro with UAC at its maximum, and the steps were correct. As it states, you have to (rather laborously) manually install the non-signed driver.

We just want to find the favorites toolbar in windows 10.
