I am unable to install the fastboot driver under Windows 10. I tried the driver suggest in Sony's intruction but run into a hash value error

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

I tried to disable driver signature enforcement but that is impossible due to the secure start guidelines

So I guess I simpy need the driver. But were to find?

PLEASE NOTE: I am aware that this problem already was addressed in various other threads on TJC relating to bootloader unlock. But none of them helped me and no thread was specific to the fastoot driver needed

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

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

error.

Then, I tried the driver linked to in Jolla's intructions found in the "Xperix X Driver" folder 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 is was impossible due to the secure start guidelines

So I guess I simpy need the driver. But were to find?

PLEASE NOTE: I am aware EDIT: GOOD NEWS! Here is the solution that this problem already was addressed in various other threads on TJC relating to bootloader unlock. But none of them helped me and no thread was specific to the fastoot driver needed

EDIT 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 shoed 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 as 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!
